People who enjoy the privileges of success must use these privileges to benefit those who do not have them. These privileges constitute a deep hole they need to climb out of if they are to prevent its being the case that the world would have been better off if they had never been born.

Kant did think he had a moral route back to rational faith in God, for those who need it, and he thought that at some level, we all do need something like it.

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

Kant certainly was sympathetic with the metaphysical tradition of rational theology that he criticized.

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.

Kant thinks we can show that there is no contradiction in supposing we are free.

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.
