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.

From a historical viewpoint, religion is just a kind of superstition, and from a political viewpoint it is a tool of social control.

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

Contemporary philosophers are facing problems that were unthinkable only one century ago, such as whether space and time are mutually Independent, whether there is objective chance or only uncertainty, whether physics can explain chemical change, whether our behavior is fully determined by our genomes, whether ideation can change the brain, or whether either the economy or ideas are the ultimate roots of the social.

Few if any political philosophers have had the courage of tackling the Cold War. Even the best of them have kept silent or have stated some bromides glossing over the serious shortcomings of "our" side, such as racism, social injustice, extreme income disparities, the exploitation of the Third World, and environmental degradation.

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

One should believe only what can be chosen to be true or just. Irrational (or unjustified) beliefs should be avoided because they can have disastrous practical consequences.
