    Between urban and digital spaces, or the material unfolding of practice

    Distance is a form of the achievable.2

    J. L. Borges

    The idea of digital spaces and cities an apparently invisible network of interactions and

    information overlapping the historically concrete and durable space of our cities, until recently the

    sensory condition of our experience has captured contemporary imagination. These terms evoke a

    somewhat unusual encounter between apparently separate phenomena distinct materialities.

    Scholars from different areas have been attracted by this new materiality, which in itself contains

    the potential for connection between events and situations, people and places in a disruption of the

    contiguity of geographical space. Taking the form of networks of hypertexts and informational

    exchange and possibilities for interaction on unprecedented levels it is a web that can connect us

    extensively all the time, beyond the need for presence.

    Indeed this intriguing fabric of materiality and its omnipresent aspect even begins to mean

    endless connectivity. Digital networks are still considered as a new space-time experience in which

    the properties of multiplicity and simultaneity of world events become increasingly clear and

    attainable as never before. If distance communication is not a new phenomenon (remembering that

    it dates from the end of the 19thcentury) it has certainly acquired new forms and enormous scope,

    involving our everyday actions and often giving the impression that we live in a kind of brave new

    world3 a hypermodernity creating experiences of a nature and a speed never previously

    experienced.

    Understanding the unveiling of this world based on new material foundations and a culture

    experiencing rapid technological acceleration means understanding how the coexistence of urbanspaces and digital networks arises and affects our lives our ways of acting, experiencing and

    socialising in material conditions that are also new. It is interesting to note that until recently the

    relationship between the concrete nature of the urban space and the elusiveness of the digital in our

    actions even seemed to be a contradiction an impossible synthesis, as if the digital put a check on

    the concrete, in an electronic overpowering of the old space, making it obsolete. A destructive and

    apparently inexorable dualism seemed to be suggested.4

    As we shall see, this dualism was overcome. We know that the rift feared by apocalyptic

    zeal has not occurred. But if there has been no rift between concrete spaces and digital networks,can we say that there instead been an interweaving? Confirmation that there is no contradiction does

    not suspend the fundamental problem that digital networks and urban networks have entirely

    different natures: the volatility, elusiveness, invisibility of one; the tangibility, rigidity and constant

    presence of the other. Where are the connections, the points of support between the digital and

    the concrete? How do these planes of different materiality involve action?

    This work aims to answer these questions beginning with an investigation of the nature of

    urban and digital networks and their roles in the production of social practice or association. We

    shall then move on to see how practice emerges and bifurcates between these two networks, the

    urban and the digital. This paper addresses the coexistence of these materialities, apparently now

    resolved and naturalised in practice. It is theory which now needs to make efforts towards

    understanding the conditions and modes of this coexistence. Three points of interconnection and the

    return of practice to the concrete are suggested: meaning, the body and the centrality of the subject

    acting in the place. It involves exploring a role of urban space that is potentially renewed by what

    we shall see as a growing complexity of the social world. Finally, I shall argue that in the current

    development of practice in diverse communication networks urban space is becoming increasingly

    removed from its original role as a material environment that is highly central in social reproduction

    for one among many environments but with the incorporation of a new ontological role: as a

    fundamental counterpoint to the elusiveness and partiality of digital communication networks.

    In different spaces

    These questions central to the understanding of the place of cities and digital networks in

    contemporary life address the way in which the two supposed forms of space relate to each other;

    and also where their contact touches on human practice and how it affects our form of life, the

    capacity and possibility of associating our acts and testing their continuities. These issues arouse so

    much interest because they relate to the nature of these different material networks and to their own

    possibility of relation.

    We certainly need something more than descriptions of informational action produced

    through digital media; instead, descriptions of the actual entanglements of acts bifurcating into

    different materialities, or how those acts form and unfold in urban networks and electronic and

    telematic networks: the concrete and electronic places they arise and emanate from; the points of

    passage between them and the trajectories taken; where they occur and eventually their return to

    their places of origin, in the form of responses, reactions, and continued interaction. Practice is

    defined as acts of human doing, therefore involving objects, signs and meanings produced bygestures or speech, in texts and in hypertexts objects, signs and meanings that are transmittable

    and understandable by other people, involving agreement or disagreement, omission or reflection

    leading to new acts.5Social practice involves effects produced in the mutual nature of acting, and

    acting in a socialised world.

    The challenge here is to understand how social practice develops in apparently separate

    spaces, with points of convergence and divergence between them. The first problem in terms of

    reading cyberspace as part of a socio-technical reality of growing penetration and scope is to

    grasp the complexity of the framework of practices unfolding in two types of networks. In other

    words we have to understand how our practices unfold in interactions and exchange, effects and

    results that connect and spread, partly through urban space and partly in electronic networks and

    mobile communications.

    The second problem is to understand the practical and cognitive bases of the connections

    and the material and ontological foundations that make them possible and give them substance. If

    description of the frameworks of social practice in these material conditions initially seems trivial

    (in view of the naturalisation of our experience) or impossible (faced with its huge complexity and

    elusiveness), description of what maintains the integrated frameworks as networks coupled together

    touches on the counterintuitive. It involves understanding the conditions of the possibility of

    producing communicative and technical networks that shape social and material reality, which are

    perhaps asymmetrical in scope, presence and expression in practice. Understanding these two

    problems means finding new descriptions. The first description relates to how we act immersed in

    spatial and temporal dynamics that increasingly break down the profound association between

    distance and time inherent to the historical constitution of practice and demand constant updating

    and changes in our understanding of the world that is presented. A second description would touch

    on the conditions that ensure integration of these frameworks and their potentially infinite

    ramifications.

    5 I use this definition based on the concepts of social action in Weber (1978), communicative action in Habermas

    (1984) and communication in Luhmann (1995).

    The nature of concrete spaces and digital networks

    An infinite number of terms has been employed in attempts to describe the intriguing materiality of

    so-called digital spaces: cyberspace, A graphic representation of data abstracted from the banks of

    every computer in the human system (Gibson); the new information network or grid of computers,a huge megalopolis without a center, the cybercity(Boyer); the information city and the space of

    flows (Castells); the post-metropolis (Soja), the unwired cities (Townsend) of post-mass

    communication networks generated by mobile technology and ubiquitous and intrusive computing;

    the infobahn, the City of Bitsor theNet (Mitchell):6

    The Net negates geometry. While it does have a definite topology of computational nodes and

    radiating boulevards for bits [] it is fundamentally and profoundly antispatial [] the Net is

    ambient nowhere in particular and everywhere at once.

    Cyberspace and its theoretical variants even raised the idea of dissolution of the city as we know it,

    a movement known as the end of geography by the economist Richard OBrien, and the death of

    distance by another economist, Frances Cairncross. Bill Mitchell summarises the process:

    The bonding agent that has held this whole intricate structure together [] is the need for face-to-

    face contact [] proximity to expensive information-processing equipment, and for access to

    information held at the central location and available only there. But the development of inexpensive,

    widely distributed computational capacity and pervasive, increasingly sophisticated

    telecommunications systems has greatly weakened the adhesive power of these former imperatives,

    so that chunks of the old structure have begun to break away and then to stick together again in new

    sorts of aggregations.7

    Naturally, apocalyptic statements like these were firmly countered:

    What is remarkable is how very little criticism depictions like this and other similar readings

    around notions like cyberspace have received. [] even though the account offered is chock full of

    cardinal errors: riven by a technological determinism that constantly transposes the characteristics of

    machines on to human subjects [] indifferent to the constant backup work that is needed by

    mediaries and intermediaries to keep telecommunications instantaneous [] Most serious of all such

    &

    accounts fail to sense the continual process of slow adjustment in practices [] the addition of new

    cultural layers which negate the idea of a simple transmission from technology onto space.8

    Crang and Thrift refer to questions that still resonate today: is space changing under the impact ofnew technologies? Could these technologies change the relationship between society and space?

    With the passing of time, theorists like Saskia Sassen have shown that there is no need to fear for

    our cities: technology will not lead to their apparent end at least not in the foreseeable future9.

    This understanding has even led to an enthusiastic reversion in defence of concrete spaces, from

    Peter Halls city of the coming golden age to Edward Glaesers recent and frankly optimistic

    Triumph of the City.

    But we shall see that despite overcoming the dualistic conflict of space versus technologies,

    questions about the ways in which practice unfolds between the possibilities offered by an

    information economy and the historical material means of the city itself remain open. These

    questions are still largely answered by reifications, now about the supposed impact of technologies

    on the actual configuration of the urban space and on our experience. So although I do not intend to

    expound a genealogy of the worn debate about new technologies making concrete spaces obsolete, I

    would suggest that the way in which the new digital networks impact on the possibilities of human

    practice and its relationship with space lies at the root of these issues.

    Space in practice

    Unlike the so-called cyberspace of information and communication technologies, space is defined

    by its comprehensive rigidity, which gives the artificial space of architecture and the city its

    particular perception to the senses, and a place in language a name. Indeed, space can be defined

    as the opposite of an abstract space or ether. Or rather, space can be defined by coexistence of

    rigidity and ether, given that we act in empty spaces structured by the rigidity of tangible,

    visible spaces; an ether that, although penetrable, is resistant to change precisely through being

    defined by rigidity. In contrast to an apparent ubiquity of telematics and electronic networks that are

    elusive in themselves but which depend on physical nodes and network devices for their existence,

    urban space is a constant presence in social practice10

    .

    But if its rigidity forms the physical extent that separates in distance, on the other hand it

    links and connects as structure networks of space connected as channels of movement (streets)

    linking active nodes (buildings) and forming systems of access and activities that allow our

    I am referring to the fact that world population is intensifying. Recent data about this can be found at State of the

    World's Cities 2010/2011, UN Habitat (http://www.unhabitat.org/documents/SOWC10/R7.pdf).

    practices to interrelate. As networks of spaces and places, cities have a topology that more than

    echoes the one of webpages and electronic placesin the multidirectional traffic of bits.

    11

    Wherever there is collective social life there is a structuring of the physical space actions of

    producing space in the form of artificial structures on the natural geography. The city is one suchform, so far the one most adapted to societies of complex division of labour and intense

    interactivity, involving spaces laden in relation to practice. The structuring of space is an expression

    of social dynamics: the power of the search for integration in the life of social groups, the power of

    association of practice shaping spaces. This structure or inner differentiation12

    can be seen as the

    visible trace of social emergences in a rigid material form, but even so and probably because of

    this capable of providing support both to practices and to particular social interactions.

    An unusual question might help us to see more of the place of space in practice. What

    spatialities other than the urban could have the effect of stimulating high levels of co-presence and

    potentials for interaction? Spatialities spread through the landscape; a concentrated spatiality but

    without any internal differentiation or structure; a labyrinthine spatiality? These spatialities would

    be obstructions to the flow of association. Someone might point out the possibility of our

    interaction without needing to be co-present precisely through distance-communication

    technologies. But could those technologies be attained without the density of co-presence and

    communication historically provided by the densities and structures of the city?

    The city means the possibility of performing acts not through a shapeless world or

    fragmented or labyrinthine spatialities, which would render the emergence of communication

    practices mediated by the body and co-presence highly problematic,13

    but instead through material

    forms that are in themselves means for our communication. The production of urban structures

    increases the potential of space in putting actors in conditions of communication. The effects of

    these spatial structures echo through all the spheres of practice mediated by the body. Putting it

    another way, the effects related to urban space mediate and articulate every form of action and

    interaction. Urban spaces contain the potential for effects on the mutual and relational nature of our

    acts and can intensify the passagefromindividual tosocial acts.

    So the potential for the emergence of communication mediated by the body is deeply

    embedded in the actual materiality of the urban. Space has the role of stimulating (or controlling,

    depending on the society, group and urban area in question) the possibilities of communication in

    11 Removing the extent of the information and communication network infrastructure that support it, the topology of

    places and flows in cyberspace closely resembles that of the city.12

    It is hard to imagine how acts of production of space can generate spatialities that can evade any structure. However, we

    need to distinguish between structure and order and incorporate contingency and play in the concept of structure

    see Derrida, 2001).13This is an argument easily used by those who reify the digital space of communication as a reason for the obsolescenceof urban spaces forgetting that it was precisely that density of presential communicative processes in the urban that

    provided the vector of technological development that brought us distance-communication technologies.

    (

    the form of: (a) supporting the randomness and contingency of interactions and exchanges in the

    social system, based on a kaleidoscope of encounters in public spaces and access to places of

    activity; (b) increasing the potential for complementary actions finding continuity or for desired

    interactions to occur let us say, in urban centres where certain complementary activities seek tolocate themselves close to one another. This effect of urban space allows elements of causality to be

    established in the connections between certain types of practice, when space helps to bring together

    potentially interactive actors; and (c) asserting conditions for what Giddens addressed as recursivity

    of encounters, thus ensuring the continuity of interactions and their passage to a wide range of

    actual relationships, which in turn will perform the role of establishing continuities in the symbolic

    and material reproduction of groups and social systems.

    But how does social practice emerge through concrete space? How can space be part of the

    communication exchanges that constitute association? An act is not an isolated phenomenon with

    an independent existence, without connections to its surroundings. Its intrinsic connections as an act

    in the world immediately relate it to its effects and outputs, its context (acts arise through spaces

    and places) and other acts, their outputs and places (the association between people involves

    connections between their acts in time and in space).Neither can urban space be experienced in

    isolation, or find an independent existence or have effects only upon itself. While our practices

    continue to be related (that is to say produced through continuities and references to previous

    practices, those in process or in the future, their contexts and their effects), their spaces will take

    part in those referential connections. These connections are fundamentally shared meanings

    produced in practices14

    and conveyed in urban spaces. In other words, a substantial part of the

    inherent relationality15

    that would make up our social and material reality is achieved by

    meanings produced through references between our practices and space such as accessing the

    workplace to carry out activities cooperatively, looking for a particular service in a certain street

    and there engaging in activities in progress or meeting friends in a bar. The practice of association

    requires actors to test relations as they act: a construction that includes physical presence and

    communicative exchange; connections that include a dimension that is as informational as it is

    material; connections that take the form of the spatial contexts in which we act.

    However, this description of practice and space as linked together is somewhat general.

    How do such connections materialise in reality, in everyday life? Urban space has different

    presences in the association of practice.

    14The idea of the signified as an effect of practice derives from Wittgenstein (2001).

    15See recent debates in human geography, performative approaches and actor-network theory, such as Thrift (2008).

    )

    (i) Space is appropriated as a source of information16

    for practice. Urban space is a form of

    knowledge about the social fabric and the way in which it is structured and reproduced. Space is a

    way of the social world presenting itself to itself. We are participating in a social situation if we

    know that it occurs, or possibly occurs in a particular place. We are guided to that place by itsmeaning, that is to say by understanding its social content as a context of certain acts that interest

    us. As we know the city and its material and semantic structures we can anticipate the possibilities

    for interaction and encounter. The city here provides a reference system for our actions.

    (ii) Then there is appropriation of space at the moment of interactionwith others present in

    the place. The spatiality of the place makes way for interaction, but considerably beyond being a

    mere physical support and visual or semiotic setting. Space can be seen as an ambiguous

    environment both material and informational that supports the emergence of communication.

    Such space laden with meanings produced by practice, a semanticized space, is the result of our

    practice. But it is semanticized when an otheractor perceives it as such, by interpreting the practice

    that takes place in it. Moreover, the space is only fully semanticized when it is enacted jointly, and

    jointly recognised as such. That space of socially recognisable meanings is the result of the actual

    association that it supports. Prior to that, space (even if intended for a particular purpose) cannot

    acquire enough meaning to inform practice. A semanticized space is the sign that space has been

    appropriated and recognised as a reference for acts.

    (iii) Finally, this semanticized space becomes part of the practical and informational

    connections between acts or eventsin progress or to be produced at other times and places. This is

    the formation of communication networks beyond the temporal and spatial boundaries of the event,

    when actors interact with absent actors through distance communication (through the exchange of

    objects, accessing texts, hypertexts or with mobile devices). This third moment leads to the

    formation of complexes of social interaction, and includes space as mediation and articulation in the

    production of a highly ephemeral form of social structure: the emergence of social systems as

    recursive communicative achievements in the here and now.17

    We relate to spatial contexts so

    that the effects of our practices can relate to each other through them: so that our practice is felt by

    and can touch other actors.

    A large part of the connections between our practices and their effects (and until recently all

    practice) takes place through spaces shaped artificially in the form of cities. That relationship is

    essential for social reproduction. Urbanisation was historically the pathway to the intensification of

    communicative practice, and the contemporary urban space continues to exercise precisely that role.

    16For examples of the view of space as information, see Haken and Portugali (2003), Portugali and Casakin (2003), andNetto (2005).17

    This idea of volatile social structures as communicative effects derives from Luhmann (1995).

    That is the central idea of association through a referential space, the inseparable relationship

    between practice and space and the place occupied by space in the production of channels of

    references that connect our acts and their results to their contexts of realisation.

    Digital networks, hypermodernity and the materialisation of practice

    Notions of cyberspace and digital spaces have acquired considerable popularity, but what

    exactly do they involve? One of the key elements of the change we are experiencing is the growing

    use of computers in carrying out our practices and in putting them into operation, associating our

    progressive involvement with semantic signs and content in the continuous production of

    information, and our immersion in the communications allowed by new technologies. From a

    functional point of view these technologies have led to increased speed and precision of actions and

    the control of their results.

    Practices previously carried out in the physical world of presential interaction and planned

    in the analogue register of the physically printed sign are now realised in the technical interface of

    electronic media. Their products lose tangibility and are re-codified in the apparent immateriality of

    the electron, represented in shapes and symbols as machine code; re-materialised in the invisible

    and impalpable world of the bit.The use of computers involves and absorbs our practices making

    its projection of the digital world of the bit inside computers the means for the materialisation of

    results. It launches our practices into a kind of third nature beyondboth the ecosystemic and the

    artificial urban system that we produce.

    The sense of partial invisibility of the operations and effects and results of practice

    mediated by digital technologies is further expanded by another particular aspect. Texts and images

    acquire the possibility of moving and replicating themselves infinitely, instantaneously re-

    materialising in any other place that is connected. The effects of our acts are able to travel without

    the material support of the physical artefact, and can affect people we have never seen and never

    will see.

    This environment is formed by the apparent omnipresence of the bit, and takes the

    historical form of an inexorability of the immersion and conversion of practice to the digital; an

    immersion in the unbearable lightness of the bit, to ironically paraphrase Kundera, exponentiated

    by the possibility of emitting the effects of our acts, now converted into the imponderable flow of

    electronic bits to anywhere with a device capable of decoding the flow and re-materialising it on the

    screen or machine. This environment finds physical form and certainly a physical connotationin

    our imagination, since we can no longer imagine all its ramifications, or where its nodes really

    come together: the electronic webthat connects computers and everyone with the conditions to use

    "+

    them. The web becomes another place (every and no place, as Bill Mitchell would put it), another

    possible environment. Socialities are apparently available at the click of a mouse. Practices of

    interaction across distances begin to form in the paths of this virtually infinite maze. Computer

    screens, tablets and mobile telephones provide their users with entries into cognitive worlds. Themoment of looking at the screen means entering into an informational space. This would be no

    different from reading a book or any tangible work, apart from the fact that these technological

    artefacts are able to access a practically infinite number of pages and relate to each other, and apart

    from the fact that looking inside them means looking at things made in distant places. It means the

    possibility of immersing oneself in the communicative flow between absent actors, in exchanges

    that are as synchronic as they are diachronic, in messages and content waiting to be accessed

    through the screen and this cognitive space.

    Informational space is certainly created in the relationship between the presence of the body

    and the electronic artefact in a physical place, but the bodily subject is no longer just there in the

    physically circumscribed space. We of course know there is no digital space hovering in the web

    of cables supporting the circulation of an electronic flow, but there are personal cognitive spaces

    connected and stimulated digitally. There is a space of topological connections between machines

    and minds genuinely integrated into information flows when in contact a topology with no

    relevant dimension in a concrete sense: the connection between the screens and digital passages

    supported by devices that intermittently receive our attention and become bridges to interaction

    across space18

    . Our attention in the here and now alternates between our surroundings and our

    connected screens of many shapes and sizes .

    This environment re-signifies, through pure contrast, our presence in the concrete, in the

    second and first types a re-signification induced by the possibility of immersion in texts and

    images that are in fact nowhere but which seem accessible everywhere in this third environment in

    which practice seems immersed. That immersion, which takes the form of a dematerialisation of the

    effects of our actions and their re-materialisation in the form of the bit, requires our cognitive

    repositioningin relation to the concrete portion of our spatial practices within reach of the body. It

    demands a repositioning of the subject towards the partial dematerialisation of the results of her acts

    and increased transpatiality the break with the extent and contiguity of space as a fabric

    adhering to action and the movement of the body and communication in co-presence.

    The relation between space and body and the status of practice in this new ontological

    condition is still tensioned by an acceleration of the historical rupture with the dependence of

    tangibility and presence.Such ruptures require the subjects (conscious or otherwise) redefinition of

    18See the notion of topology in Mitchell (1995).

    ""

    her action and possibilities in the face of the increasing means of conversion of actions and their

    effects into such virtual, invisible maze of connectivity.

    The convergence between practice and the technologies and flows of the bit appear to the

    subject, in their extent and consequences, as a growing virtualisation of the world. Action does notbecome virtual in the sense of being less real but instead in the sense of becoming partially

    invisible, imponderable, since a large part of the world within my reach19

    is substantially

    produced, associated and experienced in a world whose frameworks are becoming increasingly

    digitised. This new status of practices spatiality and temporality and its new, apparently endless

    connectivity is part of the difficulty in understanding the changes being experienced by our culture.

    Epistemologically, this complexity was foreshadowed in the idea of postmodernity, the

    crisis of modernity and the break with the modern, technological and evolutionary view of the

    world from the 1960s onwards a period of relativizing the centrality of reason, in which a sense of

    order was replaced by acceptance of instability, by an idea of absence of centres and a questioning

    of the existence of dualisms and structures20

    . But many people also believe that modernity was not

    really overcome and that rather than entering truly postmodern times we are in fact experiencing an

    acceleration of the modern experience via technology: a hypermodernity.21

    In this view, modern

    principles are not exhausted but instead acquire more profound form in certain aspects, even

    absorbing the problem of instability and flexibility in social structures and relations, and in relation

    to growing reflexivity on the level of the subject.

    Hypermodernity absorbs this reading of instabilities not as an epistemological necessity but

    instead as process and events shouting in the world outside: in the globalised economy

    synchronised in real-time by computerised production technologies in networks of flexible

    geometry (as geopolitics); in the regime of speculative financial accumulation and the casino of

    The electronic web that became popular with the introduction of the Internet is being

    progressively associated with another: telematic webs of mobile communication are popular and

    evolving in new technologies, exponentiating communication with the mobility of transmissions. A

    new period of communicative explosion came into being in the convergence of these two websthrough mobile technologies, with mobile phones practically everywhere and connected to the

    World Wide Web, together with other portable devices like Palms and laptops, Wi-Fi wireless

    internet networks and short-range webs.24

    These networks and devices form the new media of

    post-mass function with growing connections, allowing actual bilateral exchange of information,

    as effective communication: the passage from the static interface of computers or fixed digital-web

    nodes to the interfaces or mobile nodes of cell phones and other portable devices with internet

    access. Cyberspace relates intimately to traffic in the streets, enveloping actors in a generally

    connected environment. The anthropomorphism of mobile devices and communication networks

    has penetrated virtually all fields of practice, creating new ontological conditions deeply associated

    with the mobility of the body itself.25

    Mobility and its relationship with other means of practices transpatial association and the

    dematerialisation and re-materialisation of the effects of practice transmissible and replicable

    transpatially form impressive ontological properties of access to the multiplicity and simultaneityof

    acts and events. We are experiencing a materialisation of Henri Bergsons simultaneity of events

    and simultaneity of flows, the apparent possibility of events entering within a single,

    instantaneous perception26

    in a connection almost filled with places, socialities and subjects on a

    global scale.

    In hypermodernitys compression of time and space27

    we also experience the impression of

    the ubiquity of another property, connectivity beyond contiguity.The ontological place occupied by

    23 The localisation of centres of hardware that support the electronic places of websites is becoming increasingly less

    relevant when the information is progressively maintained and stored inconstant circulation.24

    The presence of cyberspace: at the end of 2010, 2 billion people had internet access, 1.6 billion of whom connected in

    their homes amounting to 30% of the world population; 71% of the population of developed countries, 9.6% in Africa

    (source: UN International Telecommunications Union, http://bit.ly/cAqMbS). Digital sources are replacing TV, radio and

    newspapers as the man source of information for 61% of the online population in the countries investigated (source: BBC

    Brasil, http://bbc.in/co2hFM); 350 million people send messages everyday via Facebook (source: TechCrunch,

    http://tcrn.ch/c2FHS3); 82% of children in 10 western countries surveyed have a digital footprint before the age of two

    (source AVG Internet, http://bit.ly/bihFYw). The presence of mobile communication: there were an estimated 5.3 billion

    mobile phone subscribers worldwide at the end of 2010. Almost 200,000 mobile phone messages are sent every second.

    Access to mobile networks is available for nine out of ten inhabitants and for eight out of ten rural inhabitants (source:

    /UN/ITU, http://bit.ly/cAqMbS). In Brazil in 2009, there were 173.9 million accesses to the Personal Mobile Service

    (PMS) (source: Anatel, http://bit.ly/fOk5fW). Data accessed in November/2010.25

    See Silva (2006) and Santaella (2010), respectively. Another potentially powerful aspect of the convergence of

    technologies and spaces in an effective hybridisation in terms of perception is the introduction of augmented-reality

    technologies. Devices can add virtual layers to perception (with the use of devices like lenses, which are still in

    experimental phase). During use, these can create layers of different information and a tensioning of commonly perceived

    reality.26

    contiguity in our readings of social and material reality is somehow destabilised by the assertion of

    a topology beyond concreteness,possible only through a break with the absolute continuity of space

    and able to align globally distributed events in a single temporality in our cognition. Channelling

    practice in this topology of connections and shortcuts of the concrete materiality of urban andgeographic spaces leads to the definitive establishment of what we might term a topological

    understanding of the world,in which socialities, places and subjects suddenly seem attainable. The

    ontology of a social and geographic world becomes penetrable and intelligible in its apparent

    totality through the concept of network, popularised and turned into a paradigm, as if the diagram

    representing the huge planetary social world were becoming flatter and flatter. An ontology in

    which historicity either collapses or becomes invisible through the impression of an eternal present,

    introduced by access to the simultaneity of agencies and situations appearing globally, all the time

    visible and recordable as never before by cameras and communication devices carried on the body.

    Nonetheless, and precisely because of this, we are affected by the exponentiation of an

    overwhelming property: complexity in terms of information in volumes that are impossible to be

    processed (pages and hypertexts that will never be known; actors suddenly becoming closer and

    closer through electronics in webs that are increasingly connected but which cannot be sufficiently

    known). Contemporary complexity is even felt in the problem of choice in this infinite option of

    signs, meanings, acts, actors this second aspect visible in Niklas Luhmanns concept of

    complexity. I shall move on to explore a role of urban space potentially renewed paradoxically

    by this growing complexity of the social world.

    We have discussed the nature and role of digital and mobile networks of trans-spatial

    communication, the webs of urban spaces as reference systems for the presential emergence of

    practice as social practice, and the social as a system of practices. We shall see how human

    practice unfolds in these two entirely different networks of materialities.

    Unfolding practice into urban and digital networks

    What is the connection between the practices we perform in the form of urban processes and in

    cyberspace? Both networks become part of the connections between acts and are fundamental

    means of communication as frameworks of recognisable and interactive acts. We naturalise these

    relationships. But thinking again counterfactually for a moment, we can see the real as

    improbable as Luhmann would say the conditions of this naturalisation. Given that human

    practice has become more complex as it has bifurcated into two distinct, albeit interconnected,

    planes, one problem is to know how these interconnections are produced and structured the way

  • 8/13/2019 Between urban and digital spaces, or the material unfolding of practice

    14/22

    "%

    in which these different networks link together in practice; a practice that is quickly adapted to

    these passages: the possibility of unfolding into multiple places and material networks.

    A second question is to understand what prevents such a system of practices becoming so

    complex as to be partially disconnected, in possible gaps in its frameworks, through loss ordifficulty in the search and selection of information and cooperating actors. I would like to suggest

    five aspects of the passage of practice between different, possibly asymmetrical material networks

    of communication, and the complex interweaving of these networks.

    (1) In cognitiveterms, these interweavings involve the form in which circulating meanings

    and messages connect with the concrete. I would suggest that the passage between acts materialised

    in urban and digital networks occurs according to mutual referencesbetween meanings with which

    connection or communication is established. The sign can travel wherever the references take it

    and momentarily connect it; where its meanings make sense; that is to say where meanings

    produced in the urban place complement the meanings of signs circulating in cyberspace, and vice-

    versa. Acting while plugged in to the transpatial web means bifurcating our acts and merging their

    meanings and effects (previously fixed to their spatial context) with meanings produced and

    circulating in other places, which connect us to actors who are not present. Urban space is more

    than mere physical structure: it is a system of references whose places contain embedded meanings

    that suggest latent connections to simultaneous, past and potential acts. Connections between

    meanings do not end there.

    If the references make sense, meanings enacted in places produce potential connections

    with those in other places, connected by the digital web. Meanings enacted in urban spaces form

    referential bridges between frameworks of acts produced in these different planes of materiality.

    Urban and digital networks are therefore tied together kaleidoscopically and changeably, in a kind

    of constantly changing tangle. Meanings are a medium of connectivity and provide direction in the

    unfolding of practice in different spaces, therefore asserting continuity between acts performed in

    urban space and those performed in the fabric of cyberspace. In our cognition this connection

    happens in flashes, such as when we take part in an activity or social situation defined by the

    borders of architecture or urban places. The contextual meanings produced there by our actions and

    communications define the scope of attention to meanings and messages and social events accessed

    digitally or telematically. But how does that connection occur in the passage from cognition to

    practice?

    (2) In practical terms, the interweaving involves forms in which we convert this cognitive

    continuity, constructed by references shared between actors, and urban and electronic places, into

    sequences of acts performed on different planes of materiality. These flows of acts unfold into

  • 8/13/2019 Between urban and digital spaces, or the material unfolding of practice

    15/22

    "&

    different materialities, to then converge and return to the concreteness of the place and the body that

    form the nodes and frameworks for our acts. Practice converts signs and images using mouse,

    keyboard or screen into codes, invisible bits, emitted and infinitely replicable. The products or

    effects of our acts converted into bit flow (or electromagnetic wave) and transmitted via digital ormobile networks are then reconverted into words and images in (an)other place(s) where, their

    meanings recognised, they can intervene in and affect the actions of other actors. Once related to

    the meanings of this new place or places and their physical acts, and transformed by such acts, they

    can once again be electronically conveyed to other places and actors. The power of the references

    contained in the meaning structures and opens out these connections and allows practice to unfold

    coherently in multiple places and agencies (Figure 1).

    Figure 1 Passages and division between digital networks (partially dematerialised, mobile and trans-

    spatial) and the urban space (concrete, extensive and physical) through referential connections between act,

    context, message and flow.

    (3) New information technologies have the effect of generating an increasing complexity of

    the social world: information in volumes that are impossible to process (Castells definition of

    complexity), and the problem of selecting from an unlimited choice of signs and meanings, acts and

    interacting subjects (Luhmann)28

    . In other words, the increased possibilities for action and

    interaction and the progressive break with the extent of the physical space have created a problem

    in reproduction of practice: how to find particular information or actor, object or artefact in

    conditions of apparently endless choice. We are forced to filter and discriminate between an

    enormous number of options. Commerce offers a notable example.29

    In the traditional retail system

    28Castells (1996); Luhmann (1995).29

    Recent research has emphasised face-to-face contact and dissemination of information between producers and

    consumers. See Florida et al. (2010).

    "'

    of clients purchasing products in physical stores, the level of choice is restricted by the amount of

    space on the available shelves. Electronic-commerce websites, however, offer selections that can

    never be fully known. Search tools and websites are one way of converting limitless choice into a

    manageable set of recommendations. In this context, choice limited to a local scale makes thedecision-making process easier.

    I would like to suggest that, perhaps paradoxically, the role of the urban space is potentially

    renewed by this exponentiation of complexity. We may see the city as a form of projection of

    possible practices or those in progress, which stimulate interactions and therefore the production of

    meanings (in objects, speech, texts and hypertexts), thus increasing social complexity.30

    At the same

    time, urban space is a mode of social information that enables actors capacity for knowing and

    engaging in acts that make up the social world. The production of space as the location of actors

    and possibilities for materialisation of their relations consists of an arrangement and pre-selection

    of situations of action. The urbanisation of space is a form of connecting acts which is produced to

    converge material and immaterial flows. Cities express social practice as a constellation of agencies

    arranged spatially through urban structures. Their concrete materialisation, in the form of

    production and occupation of spaces, and fierce competition for localisation and proximity to actors

    in potential interaction, arises as patterns of distribution of more easily recognisable and reachable

    activities. I suggest that at this moment the moment of urban structuring cities form a powerful

    everyday form (cognitive, practical) of reduction of social complexity.

    Ultimately, cites are a fundamental part of the cycle of societal continuity: a form of

    projecting, increasing and reducing social complexity at the same time, paradoxically. This cycle

    which culminates in the reduction of social complexity by the production and appropriation of

    urban space takes on a self-referential form that defines the city as an active material counterpart

    in social reproduction. Space becomes a way of making the relationship between acts, actors and

    their production possible in Luhmanns sense of rendering social reproduction sufficiently

    unproblematic.

    (4) Hugely complex, substantially invisible, never entirely knowable, the flows of

    referential connections between acts and their effects even digitalised can be penetrated and

    referenced by means of urban space. They are substantially produced and structured through

    meanings and structures latent in human spatialities. Networks of communicative actions are

    actualised through cognitive references say, when we are able to mentally anticipate our

    participation in a certain social situation, and when we actually act within these situations. Urban

    30In this section I explore the particular relationship between information, complexity, selection and social structuration

    in Niklas Luhmann (1995) as a way of exploring the place of urban space in processes of social reproduction in the face ofthe challenge of selection, between growing possibilities of action and communication, during the performance of the

    action itself and in face of the mobility of people, information and objects (Urry, 2007).

  • 8/13/2019 Between urban and digital spaces, or the material unfolding of practice

    "(

    spaces and digital networks become mutually referential systems of communication and connection

    to a diversity of socialities and experiences, capable of relating meanings, information and artefacts

    produced or encountered within them.

    (5) We come finally to the role of new electronic spaces in the practice of socialinteraction. William Gibson, the author of Neuromancer, recently said, I was never interested in

    Facebook or MySpace because the environment seemed too top-down mediated. They feel like

    malls to me. But Twitter actually feels like the street. You can bump into anybody on Twitter.31

    The parallel between urban and digital networks in Gibsons observation about which electronic

    place or tool for social interaction most resembles the properties of the street illustrates both the

    paradigmatic position of the public space and the difference and limitations of different electronic

    spaces. The street is the space where distinct identities can be co-present in a non-programmedway.

    The chances of effective communication are slight, but this fortuitous and volatile encounter is

    where the possibility is constructed of recognising the Other in its idiosyncrasies, along with the

    knowledge of the social as a complex fabric of identities.32

    Structurally social systems need both the randomness of contactin the generation of social

    relations and the recursiveness of the encounterbetween acquaintances and practices for preserving

    social ties as the basis for their own reproduction. Electronic social and mobile communication

    networks seem so far to offer less space for the randomness of co-presence. By tending to be used

    in the interaction and reproduction of ties between members of pre-identified and selected groups of

    individuals, they act as forces for affirming social fields rather than transversal integration of fields.

    These risks of dissociation and tendencies for the partial breakdown of social fields need to be

    compensated forgiven that their elimination is impossible through their composition by other

    processes of recognising the Other and possible interaction. Interaction is focused on the most

    fundamental aspect of proximity: face-to-face communication. And the city is a rich melting pot of

    interactions, information and unforeseeable exchanges, which cannot easily be replicated in

    electronic or technological spaces of distance communication. On the other hand the convergence

    of transpatial communication technologies has provided a more intense connection with urban

    space.33

    31See http://brooksreview.net/2010/11/gibson-qotd/32

    Facebook is certainly not like the street, considering that social networks are formed by recursive contact outside the

    electronic space or through considerably controlled shared affinities and interests. The fascinating Twitter is certainly

    more open and has another role apart from a social network: it is a network of exchange of information among peers,

    Nonetheless, the message-exchange relations occur through affinities, possibly with less condition for recognising

    identities.33Mobile communication technologies and GPS positioning-system interfaces allow marking of geographical position tobe transmitted in real time to web servers, and the listing of nearby participants enables points for meeting and social

    interaction. Group actions are thus fed by mobile connection (Santaella, 2010).

    ")

    Conclusions: the materialities of practice and the ontological structure of the social world

    We shall now try to take this exploratory reflection to the starting points of the passages and

    interconnections between actions performed in situations of co-presence and those performed across

    space, i.e. from their bifurcation between different material networks, their re-materialisation inelectronic networks to their recursive return to the place of presence, and the urban networks of

    face-to-face communication. I argue that even the frameworks of actions of elusive materialities

    have their origins in the concrete spaces of the city and return to it. This return is assured by the

    ontological primacy of three nodalities through which such flows must pass three conditions

    which have been jettisoned too quickly in current ontologies, influenced by the postmodernist

    critique of metaphysics: meaning as ontological connection, the inescapable physicality of the act,

    and the centrality of the acting subject and her place

    i. The referentiality of the meaning. We have seen that the cognitive connections that make

    up human interaction take in the form of meanings, in different forms, materials and means.

    Communication is a volatile fabric of meanings transmitted, interpreted, and transformed in

    perpetual circulation. These meanings have a property of establishing endless connectivity between

    things, even of different materialities. This concept allows us to find the material traces of the

    relations between our everyday acts traces active at the precise moment of association and which

    form the possibility of any association.

    ii. The return to the body and to presence. Far from reifications of bodies transforming into

    cyborgs or extended interconnection systems, the ultimate materiality of the experienced world is

    related to the body and to presence. In a time when different material systems and spaces overlap

    and interpenetrate, it is the presence of the body with its driving, perceptive and cognitive force that

    rules.34

    Even when immersed in cognitive spaces, we still inhabit the indivisible body.

    iii. The inescapable centrality of the subject and her place. We can see that cyberspace

    offers new conditions for practice and its connectivity. So we return to one of the initial questions:

    how does cyberspace affect urban space? New forms of appropriation of space have been observed

    such as locative functions, introducing new dimensions of the use and creation of meaning in

    urban spaces.35

    Digital networks and informational practices would redefine and reconfigure urban

    spaces. Nevertheless, we should avoid such reifications. Meanings produced in the informational

    territory are not inscribed in space. These re-significations are either volatile,active in the place

    during the limited time of our practices and access to information circulating in digital networks,

    34Santaella (2010). Santaella suggests that the continuity between the digital and the concrete takes place through

    perception and proprioception; but this explanation, like any other deriving from the phenomenological tradition, only

    displays the continuity of the subjects field of experience. Our problem lies in understanding how the relationships

    between acting subjects are constructed in the divisions of these different networks between players, outside theirminds.35

    Lemos (2010, p. 160).

  • 8/13/2019 Between urban and digital spaces, or the material unfolding of practice

    19/22

    "*

    and may remain while emission persists, or exist as a somewhat enclosed system,accessible only by

    those with the digital technologies or who are part of the electronic networks that share them.

    Unlike meanings imprinted by practice in urban spaces, recognisable by people in a social

    situation, meanings in the informational territory contain an inherent fragility. Actions performeddigitally and telematically do not really change the configuration of urban spaces but they can

    empower the social role of places by conferring meanings in momentary experiences. They end up

    implying a return to place as a central nodality of our practice. Besides, there is still an ontological

    primacy of subjects. However existing objectively just as tools do, and seemingly sharing a

    phenomenal symmetry in that sense, subjects have a creational role. There is no symmetry when we

    consider the role of creativity. So despite Heideggers assertion of the ontological place of tools and

    current assertions of the importance of technologies as social actors, we cannot ignore their

    ontological condition as non-autonomous tools.36

    Until the invention of artificial intelligence the

    acting subject will retain primacy in the production of information and technologies and the social

    world as it is presented.

    I have argued that the digital networks connected to virtually every computer allow

    genuinely bilateral transmission, and this fact breaks with the historical dependence on the presence

    of the body and on spatial proximity for the production of communication. This double rupture

    introduces an exponential expansion of possibilities for the connectivity of actions, together with the

    complexity and scope of action networks. The fabric of the social is structured, manifest, and it

    expands and reproduces through these networks, since the introduction of distance communication

    in the 19th century to its re-materialisation through technologies, when complex pieces of

    information become transmittable while retaining their structure intact and reproducible. We could

    also see that the end of the city is a discussion that has been surpassed, recognising the city as a

    living basis for technological production and the phenomenological centrality of the subject, the

    body and spatiality in human experience. Finally, we could see the centrality of communication in

    social reproduction. Our acts are associated by means of communication. Furthermore, face-to-face

    communication cannot be fully replaced by interaction mediated technologically: the randomness of

    the interaction of different actors and diversity of exchange of information something that the city

    historically provides are not easily replicable in digital networks just yet.37

    These introductory descriptions refer to the fundamental issue of what it is that maintains

    the integration of social reality namely, in the form of frameworks of material and informational

    connections. These frameworks include language and what the sociologist Talcott Parsons called

    steering media, the structuring means of social reproduction, such as money and power. These

    36See Heidegger (1962; 2000); cf. Harman (2010) and his theory of equipment; cf. Thrift (2008).

    different subsystems provide the ontological infrastructure that connects acts; the infrastructure

    through which the products and effects of acts are exchanged, transmitted and disseminated to other

    actors and places, and absorbed and synthesised into new acts. Electronic and telematic networks

    and their progressive convergence are considerable additions to the possibilities of integration ofsocial systems as shortcuts in the extent of concrete space. They shift urban space from its

    historical role as the sole physical means of societal integration a shift which can hardly be

    overestimated.

    When the material means of integration multiplies, the historically privileged role of the

    urban space in practice is reduced. Technological networks are dependent on subsystems of energy

    and extensive hardware, however; a dependency that makes these networks relatively fragile in

    material terms. We can add to this dependency the infrastructural and communicative conditions for

    the production of information, found typically in the spatial hardware and the informational

    software of the city. A system of nodes and connections from which the highly fluid system of

    cyberspace and its hubs is created. These are the locations where each personal computer enters the

    Web. So the fleeting materiality of these flows depends on the constant presence of spatial

    conditions.

    Considering the ontological condition of cyberspace, a counterpoint to its extraordinary

    properties is needed: a counterpoint able to (1) complement and compensate for the pervasive but

    largely invisible presence of information technologies; (2) constitute a material and informational

    resource in managing the growing complexity of the social; (3) constitute a means of introducing

    both randomness and recursivity in the generation of social relations and encounters, which will

    allow stability of interactions. Urban spatialities therefore retain their centrality as the locus of

    subjects, of communication mediated by the body, the situated production of meanings and

    information, as a melting pot of interactions a way of providing support to practice in times of

    growing social complexity and abstraction. There is in short a shift in the ontological role of

    urbanised space as a material system with a central task of integrating the social system into one

    among other means but with the incorporation of a new ontological role: as a fundamental

    counterpoint to the elusiveness of transpatial communication networks. Digital networks are

    certainly going to extend and penetrate more and more into the concrete, with the multiplication of

    types of networks, technologies and media increasingly based on the materiality of electrons and the

    electronic wave but it seems that they will do so in constant dialogue with urban space, in its

    unique position in the ontological structure of our reality.
