Kant is not saying - about freedom or any other subject - anything of the form: "Not-p but we must assume that p." That's close to self-contradictory, like Moore's paradox: "p, but I don't believe that p".

In the mid-1960s, as hard to believe as it may be now, choosing to go into academic philosophy was not an imprudent career choice. There were lots of academic jobs in philosophy then.

I think the contribution people make is not proportionate to their fame or success. In fact, I think the relation is often inverse.

We usually can't know how, and we probably should not even ask, how our lives contribute to a better world.

Kantian ethical theory distinguishes three levels: First, that of a fundamental principle (the categorical imperative, formulated in three main ways in Kant's Groundwork); second, a set of duties, not deduced from but derived from this principle, by way of its interpretation or specification, its application to the general conditions of human life - which Kant does in the Doctrine of virtue, the second main part of the Metaphysics of Morals; and then finally an act of judgment, through which these duties are applied to particular cases.

I am a one-trick pony. But I have worked hard at something I would have liked to do even if I weren't paid a penny for it, and made a good living at it. You can't be luckier than that in this life, no matter who you are or what you do.

It is sad to witness the persistence in our society of the racism and xenophobia that seems to be a permanent part of our political culture. It is shameful to see politicians exploiting these human weaknesses in order to gain political power. It is most depressing of all to contemplate a future in which politicians who do this will continue to have influence over people's lives.
