Brash, ballsy, brainy, take-no-prisoners philosophy from a guy who was in his mid-twenties.

Now I understand why logical positivism and its ilk got such an enthusiastic response.

Shorter Ayer: Much of what is marketed today as philosophy isn't philosophy. It's so mistaken that it isn't even coherent enough to be wrong. Metaphysics, ethics, aesthetics, theology, and their cousins are all hereby banished. All of the opinions that have been expressed on these topics are agglomerations of words that are impenetrable by meaningful philosophical investigation and are therefore meaningless linguistic artifacts that can be of no interest except to disciplines like psychology, sociology, & anthropology. I shall now go on to solve the mind/body and idealism vs. realism non-problems, the monist/pluralist debate, reveal the nature of the self, and abolish all "schools" of philosophy as superfluous, so that we can get on with business.
