AN ACCOUNT OF ABSTRACT IDEAS
Maria Jimenez
In Three Dialogues Between Hylas and Philonous, Berkeley argues
that there is no such thing as matter that is independent from
the mind (idealism). One way that Berkeley argues this is by showing
that abstract ideas are not possible. If no abstract ideas are
possible, then everything is a particular idea. Particular ideas
are perceptions are in the mind. If perceptions are in the mind,
and every idea is a perception, then every idea is in the mind.
If all of our ideas are in the mind and ideas are all we have,
then everything is in the mind.
In this paper I will argue that abstract ideas are possible. This
will not prove that matter exists. If I am right, however, then
Hylas can argue that our idea of matter is an abstract idea, and
therefore immune to Philonous' most convincing strategies. So,
if Hylas can avoid committing to a particular idea, which would
always be a sensation, he might be able to make some headway against
Philonous.
Hylas suggests that the nature of matter might be better understood
as an abstraction from the particular sensible qualities that
we attribute to matter. The reason that Hylas' maneuver is attractive
is that Philonous' argument to this point has been to show that
we only have access to our ideas. We do not have an immediate
impression of the cause of our ideas. If Hylas could show that
we have an idea of the abstract qualities of matter, then he would
not be forced by the particular sensible qualities. When Hylas
is challenged as to the source of this allegedly abstract idea,
he speculates that perhaps "pure reason" is capable of forming
abstractions (p. 29).
Philonous needs some way to address the possibility of an abstract
conception of matter. The following passages are the core of Philonous'
argument against abstract ideas:
Phil. ...Without a doubt you can tell, whether you are able to
frame this is or that idea. Now I am content to put our dispute
on this issue. If you can frame in your thoughts a distinct abstract
idea of motion or extension, divested of all those sensible modes,
as swift and slow, great and small, round and square, and the
like, which are acknowledged to exist only in the mind, I will
then yield the point you contend for. But if you cannot, it will
be unreasonable on your side to insist any longer upon what you
have no notion of (p. 28).
Later, Philonous says, "...try if you can frame the idea of any
figure, abstracted from all particularities of size, or even from
other sensible qualities" (p. 29; for further discussion, see
p. 56 ). If Hylas finds that he cannot, Philonous will conclude
that it is repugnant to believe that there should exist something
in nature that we cannot conceive. Philonous is challenging Hylas
to frame in his mind an idea of something without also framing
in mind particular sensible qualities such as shape, color or
texture. Any example of an abstract idea would be dangerous for
Philonous, as it would show that it is possible to imagine something
devoid of sensible qualities. Since Philonous' entire project
is based on showing that we have no sensible idea of matter, Hylas
is trying to show that we have some other kind of immediate idea
of matter. In order to see the kind of challenge Philonous is
presenting, take, for example, the idea of a person. We may ask
whether or not it is possible to bring to mind the abstract idea
of a person, without bringing to mind a person of a certain height,
a certain build, or a certain color.
There appears to be a way that we think about things without specifying
the exact sensible properties of that thing. We can think about
a car without thinking about a particular kind of car (Toyota
or Ford or Acura, etc.) and without thinking about a particular
shape or color. It seems that we do this when we say, are you
going to buy a car this year? In my question, I dont have a
particular kind of car in my mind since I dont know what kind
of car you would buy in the future (how could I have any idea
at all what kind of car you would buy, in terms of its specific
properties, when you havent bought it yet?) So, there must be
some way that the mind works to specify a core for particular
aspects of an idea like color, shape, texture etc. When I say
a car Im activating the core of the idea in my mind, without
activating particular properties that can be attached to the core.
Suppose we view an idea as having two components: the first component
is the core of the idea, while the second is the properties of
idea. Philonous might view this as begging the question. That
is, he might think that by supposing that ideas have cores, I
am simply assuming that the view that ideas are composed of sensible
particulars is false. It would appear that I need some evidence
for the supposing that ideas have two kinds of components.
There is some evidence for two kinds of components from a simple
game played by children. In the game "twenty questions," one player
(the imaginer) forms an idea in her mind usually of some noun
while another player (the questioner) is challenged to determine
what that idea is. The questioner is allowed to ask up to twenty
diagnostic 'yes or no' questions in order to arrive at the idea
that the imaginer has in mind. There are two strategies that the
questioner can follow. She might ask particular questions such
as, "Are you thinking of a platypus?" This is clearly not a good
plan, as the questioner will quickly reach twenty questions and
only has a small chance of correctly guessing what the imaginer
has in mind.
A much better strategy is to start with abstract questions such
as, "Is the thing you are thinking of an animal?" When the questioner
pursues this strategy, it does not seem plausible to think that
she, the questioner, has a particular idea in mind. That is, the
questioner does not have a particular animal in mind. She is using
the word animal as a place-holder for all animals. We can be certain
that the questioner has formed an idea in her mind. This is because
she able to refine the idea further and further based on the responses
that the imaginer gives. Suppose that the imaginer's answer is
'yes.' The questioner then has an idea in her mind of something
that is an animal, but not a particular animal. If it were a particular
animal, then the questioner would lapse into the particularist
strategy (by asking, for example, "Are you thinking of a wildebeest?")
The questioner might make this move after the first question,
but she need not. Again we can see that a better strategy would
be to remain at the level of the abstract by asking, for instance,
"Are you thinking of a mammal?" This point is that the idea is
guiding abstract questions, so it must itself be an abstract idea.
Is this a mere artifact of the words used in the game? Philonous
apparently thinks that we must "lay aside the words" in order
to "contemplate the bare ideas" (p. 29). It seems that Philonous
is worried that the ability of words to convey abstracts is misleading
with respect to the question of whether or not we can have ideas
of abstractions. But I do not think that the word the questioner
uses is central to issue. The moment before the questioner asks
whether or not the imaginer is thinking of an animal, the questioner
must have some idea of what she is going to ask. So animal, as
an idea, must be in her mind before she utters the words of the
question. It appears that we have demonstrated some evidence for
the claim that something can be an idea and be abstract at the
same time. |

The paper has been given a title. Notice that there is no pun,
no joke and no silliness. While it is true that some philosophers
write in a comedic style, the usual order of things is to get
famous first and cute later. |

The writer is now making a serious and careful attempt to articulate
her theory of abstract ideas. She has already established a rationale
for pursuing this topic. Now, it is her turn to advance a claim.
The student has changed the container theory to the 'core' theory.
This -- in her view -- allows her to state the theory more easily
without bringing to mind a potentially misleading analogy. What
she is worried about is that the abstract part of an idea should
not obscure the non-abstract parts. If sensory qualities were
in a container (in, say, a box), one might worry that they would
not be available to consciousness. Since sensory qualities are
available to consciousness, the abstract part must be more 'inside'
the idea. Thus, she begins to speak of the core of an idea.
Immediately after giving her account, the writer sets out to defend
it. She attempts to give evidence that her view is right. She
does not reference the dictionary or appeal to some authority.
She gives reasons to accept her view.
Specifically, she offers a thought experiment. The hope is that,
if the reader conducts the thought experiment himself, he will
come to appreciate the merit of the author's claims.
