Funny, I picked up an A.J. Ayer text just yesterday.

I agree with Bubba that you need to elaborate more fully on what you mean by terms like 'perception'. Do you mean to say that 'sense-data' are the only knowable reality?

Also, what is the nature of the association between perceptions and reality? It's unclear if you mean that reality is unknowable but still exists (kind of like believing in a god), or if you mean that we cannot know if reality exists. If you ascribe to the former, then aren't you accepting a form of realism?

And how do you distinguish between 'real' perceptions, and illusions, hallucinations and other 'unreal' perceptions?
