Reid thinks that the Aristotelians make the same mistake as the Lockeans and Berkeleians: they all think that the phenomenal qualities or “ideas” (in the Lockean sense) in our minds are similar to the properties of physical objects. Thus, the sensation of hardness when I press my hand on the table is supposed to be similar to the physical hardness of the table. But Reid thinks that a bit of reflection shows that the mental entity is quite different from the physical entity.
Presumably, the reason the Aristotelian is accused of this mistake is that the Aristotelian is supposed by Reid to think that a single objectual quality, such as hardness, is found in the table and in the mind (presumably in different ways).
However, I think the criticism of the Aristotelian fails. Let’s take the Aristotelian theory to be as Reid seems to think of it. We still have a choice as to what item in the Aristotelian view we identify with the phenomenal qualities. There is
- the hardness itself
and
- the sort-of-but-not-quite-inherence relation between the mind and the hardness.
Which one of these is the phenomenal quality or “idea”? The difficulty here is that Reid seems to accept two claims about Lockean “ideas”:
- we always have immediate awareness of “ideas”
and
- “ideas” are the states of awareness.
On the Aristotelian view in question, (1) satisfies (3) and (2) satisfies (4). But (1) does not satisfy (4), and I don’t think the Aristotelian should allow that (2) satisfies (3).
The Aristotelian can now give this story in response to Reid. If we identify (1) as the phenomenal quality, the “what I feel”, then there is nothing absurd about saying that what I feel—namely, hardness—is what is in the extramental table. If we identify (2) as the phenomenal quality, on the other hand, then the Aristotelian will agree with Reid that the phenomenal quality is not found in the extramental object, because the inherencish relation is only found in the mind.
In fact, the Aristotelian’s refusal to accept that there is a single sense of “ideas” that satisfies (3) and (4) is a very good thing. For if we accept both (3) and (4), then for anything we are aware of, our state of awareness will itself be something we are aware of, and any awareness will immediately imply infinitely many levels of higher-order awareness, which is empirically false.
I am not a Reid scholar, however. I might be badly misreading Reid.
