Science and Inten&onal Ac&on
Libet’s (1985, pp. 529-‐530) defini&on of [voluntary] ac&on: (a) it arises endogenously, not in direct response to an external s&mulus or cue; (b) there are no externally imposed restric&ons or compulsions that directly or immediately control subjects’ ini&a&on and performance of the act; and (c) most important, subjects feel introspec&vely that they are performing the act on their own ini&a&ve and that they are free to start or not to start the act as they wish. 3

Common ideas about inten&onal ac&ons in scien&fic research
• Inten&onal ac&ons have to be caused by conscious inten&ons

• Inten&onal ac&ons have to be caused by conscious inten&ons
Mele (1997, p. 243): Given that he intends to walk to work at the +me, is a reasonably pro-‐ ficient walker, encounters no special obstacles requiring an altera+on in his gait, and so on, his inten+on to walk to work can play its causal role without his having a specific, dis+nct inten+on for each step he takes.

• Inten&onal ac&ons have to be caused by conscious inten&ons, but only intended ac&ons are caused by a specific, dis&nct inten&on

• Inten&onal ac&ons have to be caused by conscious inten&ons, but only intended ac&ons are caused by a specific, dis&nct inten&on
1. The researcher is in a posi&on to determine what inten&on the subject has, or should have 2. Inten&ons are only conscious if the agent is conscious of the inten&on as a state

What the intended ac&on is depends on the inten&on of the agent
a. The descrip(on under which the events are inten1onal

What the intended ac&on is depends on the inten&on of the agent
a. The descrip(on under which the events are inten1onal
b. On what level the agent performs the intended ac1on
14
1. Can scien&sts determine what the intended ac&on and inten&on is?
What is the intended ac&on that is performed?
Depends on context and the skills of the agent (Papineau, 2015)
16
2. When is an inten&on a conscious inten&on?
Pacherie (2006, p. 160): Second-‐order consciousness: the creature has a representa+on of that state as a specific aGtude of hers toward a certain content
First-‐order consciousness: the creature whose state it is is conscious of the object, property, or state of affairs the state represents or is about
18
Repor&ng Conscious Inten&ons
Haggard 2008 Libet (1983, p. 627): ‘the subject was asked to note and later report the +me of appearance of his conscious awareness of 'wan&ng' [or having an ‘urge’ or ‘inten+on’ or ‘decision’ to move] to perform a given self-‐ini+ated movement.’

Haggard 2008
Push the buPon whenever I feel the urge to do so
What is the intended ac&on in Libet-‐style experiments?
21
Haggard 2008
Mele (2009): compare real Libet experiment with an imaginary experiment
Push the buPon whenever I feel the urge to do so
What is the intended ac&on in Libet-‐style experiments?
22
What is the intended ac&on in the rudeness experiment?
24
I am going to ask the researcher what to do next
At what point is the inten&on conscious?
Haggard 2008
Push the buPon whenever I feel the urge to do so
Second-‐order consciousness versus first-‐order conscious (Pacherie, 2006)
25
Start readiness poten&al
Conscious inten&on Movement
Haggard (2008)
The inten(on occurs too late…
Troublesome conclusions?
26
…or conscious inten(ons play no role in what agents do
Sugges&on for improvement
Ask subjects about their inten&ons, but:
1) Do not assume knowing what the inten&on with which they act is
2) Allow for different ways in which subjects can have a conscious inten&on
E.g.: What are you [inten+onally] doing?
