People often talk as though their thoughts were a constant stream of an inner voice speaking aloud in their heads. I find this strange, because unless I am rehearsing what I want to say or write, or am trying to imagine a debate between two or more people, there aren't ever any voices in my head. When I think about things, the thoughts aren't verbal; they're just there, both like weighted, kinetic mechanisms and like colors at once. I don't think: "Today I have to feed the cat, read Wittgenstein and do the dishes, and I would like to find the time to watch a movie with my girlfriend." That would be bizarre. The thoughts are just there, maybe flashes of cats and the word "Wittgenstein" and some vague notions of duty and cleaning and my girlfriend's name. I know them, without hearing them or seeing them written. So why do people talk as though there were a voice in their heads? I thought only schizophrenics heard voices.
