Take materialism to be the claim that only the physical world exists; that everything that exists is material (i.e. has a given spatio-temporal location, etc.).
If materialism is true, then thoughts are just neurons firing in x-manner and neurons firing in x-manner are just an interaction of atoms thought-wise.
Now, consider a thought. A thought is inevitably "about" something. I may think, for example, about the post I'm writing right now on the Religion Education Forum. If I am thirsty, I may be thinking about getting a cup of water. If I am hungry I may be thinking about hunger, or about the steak I left in the refrigerator. Call this "aboutness" intentionality. When I say that thoughts feature "intentionality," I am not saying that a thought must entail that a person thinking a thought must intend to do some thing or other; I am merely saying that a thought is inevitably "about" something.
Matter, however, is not "about" anything. An atom of hydrogen, for example, is not "about" anything. Seven billion atoms are not "about" anything. And so forth. Merely increasing the number of atoms does nothing to change the fact that atoms are not "about" anything. But if atoms are not "about" anything, and thoughts on this view (that is, materialism) are nothing more than a sequence of atoms interacting thought-wise, then it follows that our thoughts are not "about" anything either.
But our thoughts clearly are "about" something. Even the thought "our thoughts are not about anything" is about something, namely, that our thoughts are not about anything. So materialism must be false (or, say, some form of dualism or something similar must be true).
This can be formalized into a syllogism:
Argument From Intentionality Contra Materialism:
P1. If materialism is true, then thoughts are just a sequence of atoms interacting thought-wise.
P2. Atoms have no intentional states (i.e. atoms are not "about" anything).
P3. Therefore, (from P1 and P2) if materialism is true, then thoughts have no intentional states.
P4. Thoughts do have intentional states.
C: Therefore, (from P3 and P4) materialism is false.
Let me know what you think
