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.

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.

My Third-World roots remind me that the vast majority of our fellow human beings live hungry, sick, and uneducated, and that most social scientists, even in that world, ignore that ugly reality. This is why my papers in mathematical sociology deal not with free choice among 30 flavors of ice-cream, but with social structure, social cohesion, and social marginality.

A democratic state will protect the freedom to hold any beliefs other than those that harm others, such as racism. In particular, it will see to it that no one is harmed just because of her beliefs.

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.

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

Original philosophy is always "deviant" or even subversive.
