It occurred to me that I had the duty to give society something in exchange for the free education I was getting.

Philosophy can help laymen spot and reject the numerous pseudoscientific beliefs that survive in the media, such as the fantasies of psychoanalysts, evolutionary psychologists, and economic equilibrium theorists.

It is scandalous the way some scientists accept uncritically some of the most ridiculous speculations, such as the plurality of worlds, the opinion that spacetime has more than 4 dimensions, that particles can move faster than light, or that human life can be prolonged indefinitely.

I believe that modern science supports free will, in showing that the brain can act spontaneously, not only in response to external stimuli.

In any event, I don't believe in instant philosophy, because interesting problems take a long time to understand and work out. Just think of the problems of truth and justice.

Some of the big philosophical problems have been solved by science, at least to a 1st approximation. Examples: the problems of matter, and mind. Only philosophical reactionaries, like Noam Chomsky, claim that they are and will remain mysteries.
