Lecture VI
You see, over against the so-called categorical imperative, as it comes down from former times out of old moral impulses, there stands the summons to mankind, out of the depths of his soul, evermore to unfold love for what is to become action and deed. For however often in future there may resound: “Submit to duty, to what brings you nothing that will please”—it will be of no avail. Just as little as a man of sixty can behave like a baby can we live at a later age in a way suitable to an earlier epoch. Perhaps that would please people better. But that is of no account. The important thing is what is necessary and possible for the evolution of humanity. We can simply not discuss whether what Kant, as a descendant of very ancient times, has said should be carried on into the future. It cannot be carried on, because humanity has developed beyond it, developed in such a way that action out of love must give mankind the impulse for the future.
