It is often difficult to know about one's own era which philosophers in it will be remembered as the most important ones, but I think it is already clear that John Rawls is the greatest moral philosopher of the twentieth century.

We are generally forced to choose one way or the other of distancing ourselves from Kant. I suppose I tend to choose the irreligious way. But I regret that Kant's path has not been followed.

If being "iron headed" is to be lacking such feelings, then Kant's position is that an ironheaded person could not be a moral agent because such a person would not be rational.

Not only our moral life, but even our use of theoretical reason - on which we rely in rationally inquiring into nature - presupposes that we are free.

Kant thinks that a free will is a will under moral laws and that freedom and the moral law are distinct thoughts that reciprocally imply each other. Fichte thinks they are the same thought.

Kant considers belief in God and immortality to be items of "faith" because he relates faith to the pursuit of ends - in this case, the highest good.

My own view is that Kant's conception of the duality of the good (morality and happiness, the good of our person and the good of our state or condition) is a distinctively modern view.
