Transcript of The Problem of Universals
2
The problem of universals is a metaphysical problem. This means that the problem of
universals is dealing with a problem about the nature of reality. Specifically, the problem of
universals is a problem about commonality in our world. It asks how we understand the same
type of thing appearing in multiple instances. To better understand this idea, I would like to
provide an example. My friends and I like to play pool. I look down at the pool table and I see a
bunch of balls. I see things that these balls have in common. I see that all the balls have a similar
shape, roundness. I see some of the balls share a color, redness. I see that some balls share
patterns, being striped or solid. I see that one of the balls is green and it share its greenness with
the color of the felt on the table. I start thinking a little philosophically (maybe after a few
drinks) and I notice that not only do some balls and the table share colors, but that the table and
balls have the common feature of shape. Seeing commonality between distinct instances is the
motivation behind the problem of universals. The problem of universals asks: what explains this
commonality? The goal of this paper is to: explore the problem of universals, see how Plato
answers the problem of universals, look at some problems with Plato’s answer, and explain why
a theory of modes may be a better answer the problem of universals.
Plato puts the problem nicely in Parmenides when he says, “Whenever some many
things seem to you to be large, perhaps there seems to be some one character –the same-… and
from that you conclude that the large is one thing” (Cohen, 647 line 132). Plato is talking about
seeing different instances that share common properties. Since these common properties all
appear to be the same, he wants to call them by one name. Here we can also talk about types and
tokens. A type would be a property, like the property of red that is attached to the billiard ball.
We can talk about the tokens, the instances of the type, the redness we experience in both the
striped and solid billiard ball. Another helpful idea in understanding universals is looking at the
3
way we form sentences. When we form descriptive sentences (the billiard ball is red), these
sentences include a subject and a predicate. The subject of the sentence being the billiard ball,
and the predicate being “is red”. The predicate of the sentence, in this case, is pointing out a
common feature of reality. This means that the way we describe our world points out certain
commonalities in order to make the world more intelligible. If predicates kind of imply the
existence of universals, is our way of describing the world accurate, or is separating the subject
and predicate just a manner of speaking? This is not to say, however, that our way of talking
about the world gives us a direct vein to the way the world really is, just that we need examine
why we speak as we do in order to see if that manner of speaking is an accurate description of
reality.
In answering the problem of universals, there are two ways of going about it. The first is
the realist perspective. The realist holds that universals are indeed real. They believe that the
predicates in the subject-predicate distinction are in fact something distinct from that which they
are attached to. Then, there is anti-realism, the anti-realist denies the existence of universals.
There are two different types of anti-realism I will explain in this section, all with a different way
of explaining commonality.
First, let’s look at extreme realism. Extreme realism holds that the universals exist
independently from there instances. They believe that there is an individual, and there is a
quality. The quality is the universal. This universal is exactly the same in all of its instances.
There are the individual substances that are unique (or numerically distinct), and then there is the
universal along with that substance. Since the extreme realist believes the universal is one entity,
which attaches to multiple substances, the instances of this one universal are strictly identical.
4
Then there is the strong realist. The main difference between strong and extreme realism
is that the strong realist denies independently existing universals. “A universal on this view is
just the quality that is in this individual and any other qualitatively identical individuals”
(MacLeod and Rubenstein pg. 5). For the strong realist, if I were to remove all instances of the
universal, the universal would cease to exist. This would not be the case for the extreme realist,
however, since the universal exists separately from the substance. Now that we have looked into
the two realist views we can see some opposing anti-realist views.
The first anti-realist view we’ll be looking at is predicate nominalism. The predicate
nominalist completely denies universals. They say universals are just a manner of how we
describe the world. This makes commonality purely a function of how we describe the world. So,
the green in the billiard ball and on the table’s felt, are only both called green. We just call them
by the same name. For the predicate nominalist, there is no true way reality is that makes us
recognize this shared feature. In fact, the predicate nominalist takes our seeing commonality as
an unanalyzable brute fact. It is just that some ways of describing the commonality are okay
while others are not; they give no further analysis than that. (MacLeod and Rubenstein pg. 6)
A little less harsh, but still under the anti-realist umbrella is the resemblance nominalist.
“Resemblance Nominalists explain individuals shared qualities by talking only about
resemblance relations” (MacLeod and Rubenstein pg. 5). For the resemblance nominalist, then,
we only call things the same merely because they resemble each other. Since the word
resemblance is employed, this means there isn’t strict identity between two objects, just two
things that are similar enough that we recognize a resemblance, a similarity, and call them the
same. For the resemblance nominalist, resemblance is a brute unanalyzable fact. In other words,
we can’t understand why two things resemble each other, they just do.
5
Now we must examine the problem with saying things share commonality in virtue of
resembling each other. This is a problem for the nominalists. It will also become an apparent
problem for the theory I will posit later, modes. The resemblance nominalist talks about set
membership. Things are put into sets when they resemble each other more than they resemble
non-set members. Take for example the “set” game. We put football and soccer into the set,
game, because they resemble each other more than they resemble cooking or shoemaking. By
organizing sets by resemblance, however, you end up including members in the sets that are
completely dissimilar from other members. We have the red billiard ball, which is in the set (red)
with the stop sign and red apples. Since things resemble each other in various respects, the red
billiard ball is in the same set as the green billiard ball. The green billiard ball clearly has no
similarity to the stop sign, but they are stuck in the same set since they both resemble the red
billiard ball. I believe for someone who solely posits resemblance relations this problem is
overbearing. (MacLeod and Rubenstein pg. 5) Now we understand the problem of universals.
We understand some of the major ways to answer this problem. We now need to see if Plato’s
answer to this problem is better than nominalism. I will give an account of Plato’s theory of
forms, and then explain which of the categories listed above Plato falls into.
Plato’s Theory of Forms is one of the most famous theories in all of philosophy. It
can be found predominantly in The Republic, although it is brought up in many of his works. It is
used to answer the problem of universals, but for him it also answers ethical and epistemological
questions. The forms are qualities of a substance such as: roundness, triangularity, and
goodness. The forms are supposed to be perfections of qualities that exist independently from the
physical world we experience. The forms exist in a place that is sometimes called the platonic
heaven. Plato is an Extreme Realist. To better understand the forms and how Plato is an extreme
6
realist, it is important to be familiar with all of the forms important qualities. In an article entitled
Plato’s Theory of Forms, David Banach explains six important properties of the forms.
The first important property is that the forms are transcendent. Banach explains this as
meaning “the forms are not located in space and time”. Another way of putting this is that the
forms are non-physical. This is why people say that there is a “Platonic Heaven”. They are
saying that the forms do not exist in the physical world which we exist in. They are located
outside of time and space. The forms do not exist at one particular time. The forms also do not
exist in one particular space. By virtue of being transcendent, the forms are also immaterial.
Materiality is a characteristic of objects that are located in time and space. While material objects
are subject to alteration and destruction because they are made of physical stuff, the forms are
unchanging because change is a property of material substances.
The next important property of the forms is that they are pure. Banach explains this as
meaning that “The forms only exemplify one property”. This means the forms themselves do not
have multiple properties, they only exemplify one property. Let’s go back to the billiard balls.
The billiard balls have multiple properties: redness, sphereicity, hardness etc. For each of these
properties there is a corresponding form. There is no one form that contains both redness and
sphereicity. There is one pure form of redness and one pure form of sphereicity. These forms
themselves have no other quality except for the quality which they represent in the physical
world.
Another important property of the forms is that they are archetypes. To be an archetype
means to be a perfect instance of that which it is exemplifying. I often hear people talk about
archetypes in relation to people. For example; people often talk about the archetypical male, and
7
talk about someone like George Clooney as being that archetype. They say George Clooney
because they think of the qualities that represent a male, such as being handsome and suave.
They see him as being a perfect representation of these qualities. Now let’s take this example to
the forms. We have the billiard ball and one of its qualities, redness. The form, Redness, is a
perfection of the quality redness. It is perfectly red; it couldn’t be anything other than this
because the forms are pure. If the forms were not perfectly red, that would mean there is some
other quality at work.
Banach’s next important quality he ascribes to the forms is that they are Ultimately Real.
This quality is given to the forms because they are unchanging. The instances of the forms in the
physical world are subject to change and therefore, not ultimately real. Since the forms are
fundamental, they are not subject to destruction like that of the physical world. The material
objects we experience are mere copies of the forms.
Also important is that the forms are Causes. This quality is given to point out that the
forms are the causes of all things. The forms explain why anything is the way it is, this is
because the forms are the source of being for all things. According to Plato, if the forms did not
exist, no other things could exist. This means that the forms precede the physical world. The
instances in the physical world did not cause the creation of the forms. The existence of the
forms caused the existence of the physical world.
The last important property of the forms is that they are Systematically Interconnected.
This means that the forms are connected to each other as well as to the physical world. From
some forms other forms can be drawn. As I will show, I think this property of the forms is the
source for a major problem for the forms called the third man argument.
8
Using the properties of the Forms, and what we know about extreme-realism, we can see
how Plato was an extreme realist. The defining mark of the extreme realist is that he believes that
the universal exists independently of the instance. This is certainly what Plato believed and is
shown in the transcendence of the forms. The extreme realist also believes that the universal is
the same in all of its instances. By virtue of the forms being archetypal and pure, they are not
going to be different in their instances.
Problems with the Theory of Forms
I will be putting forth two problems with the theory of forms. The problem of divisibility
and the third man argument come by Plato’s own hand in Parmenides. I will describe these two
problems and I will provide a counter argument against the problem of divisibility. The first
problem that is presented in Plato’s Parmenides is what I will be calling the problem of
divisibility. In Parmenides, Plato uses Parmenides as the scrutinizer of the forms. Parmenides
asks “So does each thing that gets a share get a share of the form as a whole or a part of
it?”(Cohen, pg. 646 line 131a). In other words, does each billiard ball get a whole of the form of
sphereicity, or a part of sphereicity? Plato’s answer to this would be that the forms are wholly
present in each one of their instances. How can something be wholly present and be in more than
one place? Certainly, sphereicity is seen in both the cue ball and the eight ball. This, however,
means the form of Sphereicity is in more than one place at the same time. If the forms were not
wholly present in each of their instances, that would mean parts of the form exist in each
instance. If the forms were parts, and the parts existed in their instances, then once the instances
(the parts) go out of existence then the whole too would go out of existence. Plato’s aim is to
prove that the forms precede their instances. If the instances compose the forms, then this
certainly cannot be the case. I do not believe this is a true problem for Plato because of the
9
property of Transcendence. By virtue of the forms being transcendent, they are immaterial. “It
seems to be the mark of materiality that that things can only be in one place at one time”
(MacLeod, Rubenstein pg. 3). Since the forms are immaterial, they are not constrained to being
in one place at one time. The problem of divisibility is not a problem for the theory of forms
because they are transcendent. This does not mean, however, that the forms are unproblematic.
Let’s move on to the next problem, the Third Man Argument.
The Third Man Argument also comes from Parmenides. It is a very brief section of the
book (only from 132a-132b), but it is a very famous argument and a devastating blow to the
theory of forms. Vlastos argues that three important things must hold true for the Theory of
Forms to be refuted. The third man argument proves that Plato’s theory leads to vicious infinite
regress. It is called a vicious infinite regress because the forms are supposed to provide an
answer to how things are the way they are. A vicious infinite regress leads to no answer. From
the forms, other forms can be derived (because they are systematically interconnected). When
you try to explain the nature of a form, say Largness, you end up explaining Largness with
another form Largness. This process continues to infinity and you never get the explanation that
was originally sought. I will now explain the vicious infinite regress more in depth.
I’m walking around in New York City. I see a bunch of buildings and say “gee, these are
all rather large”. Plato would say “Of course you say they are all large! They all participate in the
form of Largness!” I will use F to represent the form of Largeness and a and b to represent the
buildings. So, a and b both participate in F. Since the forms are archetypes, F is itself large. Now,
we have 3 large things a, b and F. We now need a form to represent the largeness of these three
things known as, F2 (form of Largeness 2). Now we have a, b and F participating in F2. Again,
since the forms are archetypes F2 is itself large. So now we need F3 to explain the largeness of a,
10
b, F, and F2. Next there would be a Form F4 to explain a, b, F, F2, and F3. This vicious regress
would continue to infinity. You would end up with F100 ,F10000, an infinite number of forms of
largeness. This is vicious because we never get an explanation. Vlastos points out important parts
in the third man argument that must hold true for the vicious infinite regress to occur.
Firstly, is what is called One Over Many. This is referring to that from many we can
derive one. This is the problem of universals. The forms are posited precisely to take many
instances and provide a one that derives from these instances. In the mentioned example, there
were buildings; these buildings are large according to Plato because they all participate in the
form largeness. The one (Largeness) is derived from the many (buildings, large things). The next
important part of the criteria is self-predication. This means “any form can be predicated of
itself” (Vlastos 324). Self-predication must be true because the forms are archetypes, George
Clooney represents the archetypal male and himself is a male. The forms are perfect examples of
that which they represent. The last important part of Vlastos’s criteria is the Non-Identity
Assumption. Vlastos describes this as meaning “If anything has a certain character, it cannot be
identical with the form in virtue which we apprehend the character” This criteria is the hinge of
the forms. If the forms were identical with their instances, they would just be the instances. If the
forms were identical with their instances, there would be no forms. Since the forms themselves
have a property, they must themselves have a form over them to describe that property.
So let’s reword the argument in Parmenides using Vlastos’s terms. We have a and b
which are both large. Since One-Over-Many is the heart of the forms, from a and b we derive the
form of Largeness (F). Now Self-Predication , since the forms are archetypes, they have the
property of the instances which they represent. The Form of Largeness (F) is itself large, it must
be. Lastly, the Non-Identity Assumption. If something has a property, that property is not derived
11
from itself, but from another form. Since F has the property of largeness and, it needs another
form of Largeness (F2) in order to describe it .These same steps happen for F2, which leads to an
F3. This regress happens to infinity. We never get a description of the property. This is a fatal
blow to the theory of the forms.
The answer to the problem of universals I would now like to propose is called a theory of
modes. It comes from John Heil’s book entitled The Universe as We Find It. A mode is a
particular way a particular substance is. This is how Heil accounts for properties. He says
“properties are ways substances are” (Heil 4). Heil never comes out and says what he thinks the
substance(s) is (are), but some other philosophers who have posited modes have done so. Locke
suggested modes. His substance was called corpuscles. The corpuscles arranged in a particular
way gives rise to various properties to make the billiard ball. To better understand how properties
can arise from arrangement, think of a water molecule. A singular water molecule is not itself
wet, but when several water molecules come together the property of wetness arises. Heil holds
that properties and substances are inseparable. If you have a substance, it’s going to be a
particular way and thus have properties. It is important to note that for Heil things like tomatoes
are not substances that properties attach to. To treat the billiard ball as a substance is to treat it as
an indivisible unit. For Heil substances must be simple (indivisible). This is because the
substance must have an infinite number of potential properties, in order to account for all the
various properties. I believe this is because properties arise from arrangement. If a tomato (non-
simple) was a substance it could only give rise to certain properties (redness, sphereicity). If we
take something like the most basic constituents of atoms as basic (simple), we can account for all
of the objects and properties we encounter in the universe.
12
Now, we need to see how modes answer the problem of universals. In other
words, how do modes explain commonality? I would like to call a theory of modes, resemblance
nominalism analyzed. This means that we experience commonality in virtue of the two
properties resembling each other, but for someone who posits modes the story is deeper than
that. For the resemblance nominalist, resemblance was an unanalyzable fact of the world. The
mode theorist can analyze the resemblance. The mode theorist says resemblance occurs because
the two objects with resembling properties have similar or identical substance arrangements. Let
me give an example. We have a red billiard ball and a red tomato. Let’s just assume there is one
substance: atoms. The atoms are obviously arranged very differently in the billiard ball and the
tomato. The tomato is soft, juicy, and delicious, and the billiard ball is hard, dry, and would kill
me if I ate it. The atoms in both, however, are arranged in such a way that they both absorb
certain wave lengths and reflect the red wavelength. The arrangements of atoms in both the
tomato and the billiard ball make it so a particular wave-length is reflected. The structure of the
substance in similar enough ways gave rise to similar properties. Resembling structures is one
way that the mode theorist can explain commonality, but perhaps not a sufficient way to explain
commonality.
I mentioned earlier that at face, this theory encounters the same problem as the
resemblance nominalist. To reiterate, when you say things are in the same set by virtue of
resemblance you end up putting dissimilar things into the same class. The green billiard ball and
the red stop sign are in the same class because the green billiard ball resembles the red billiard
ball, and the red billiard ball resembles the red stop sign. This is an apparent problem for the
mode theorist as well because two dissimilar things could be in the same class. The structure of
the red billiard ball has a similar structure to the red stop sign, but the red billiard ball also has a
13
similar structure to the green billiard ball. This makes it so two dissimilar things ( the green
billiard ball, and the red stop sign) are in the same class. I believe Heil, however, gives a feature
of structure that allows this problem to be avoided.
In order for the mode theorist to avoid this problem they must reach beyond mere
resemblance. The mode theorist must posit something identical among instances to explain
commonality. Heil suggests that “properties are powerful qualities”(Heil 61). This allows a
change in the answer to the problem of universals from how the structure is to what these
structures do or would do. Back to billiard balls, a given structure makes a billiard ball look red,
and it makes the billiard ball roll. These words (look, roll) are referring to actions of the billiard
ball. Without the ability to act no commonality could be experienced. The experiencing of
commonality is what the problem of universals is all about. If the billiard balls’ structure did not
give the billiard ball the power of looking red, no red would be experienced, hence no
commonality would be experienced without powers. Using the model of powers we can see why
we place objects in the same sets. We can place objects in the same set if they have the same
power. Commonality is now based off of what these structures actually do, as opposed to how
these structures resemble each other. Resembling structures produce identical actions, therefore
have identical powers. We move from set placement based off resembling structures to set
placement based off identical powers. This allows the mode theorist to avoid having dissimilar
members in the same set. The green billiard ball is not in the same class as the stop sign and red
billiard ball because it’s structure doesn’t give it the power of looking red. Using powers on a
theory of modes to answer the problem of universals provides an unproblematic way to explain
commonality.
14
In this paper, we have explored the problem of universals. We have looked at it from
several viewpoints. We saw how Plato answered this problem and then saw problems with his
theory. This led us to a view I find particularly convincing, modes.
