"Art is long, life is short, judgment difficult, opportunities fleeting. Action is easy, thinking is hard: acting after thinking, uncomfortable. Every beginning is joyous, every threshold a point of expectation. The boy stares in wonder, impressions condition him, he learns in playing, seriousness takes him by surprise. Imitation is natural to us all, but what to imitate is not easily ascertained. Rarely is the best discerned, still more rarely appreciated. Height attracts us, not the steps upwards; with the mountaintop in our eyes we linger lovingly on the plain. Only a part of art can be taught, an artist needs the whole. Those who know only half of it, are always confused and talk a lot; those who have the whole, act and talk little, or long afterwards. The former have no secrets and no strength, their teaching is like freshly baked bread, tasty and satisfying for one day; but flour cannot be sown and the fruits of the grain should not be ground. Words are good, but they are not the best. The best is not made clear by words. The spirit in which we act, is what is highest. Action can only be grasped by spirit and portrayed by spirit. No one knows what he is doing when he acts rightly, but we are always conscious of what is wrong. He who works only with signs, is a pedant, a hypocrite or a botcher. There are many such, and they get on well together. Their gossiping impedes the student, and their persistent mediocrity alarms those who are best. The teaching of a real artist opens up sense; for where words are lacking, action speaks. A true pupil learns how to unravel the unknown from the known, and thereby develops toward mastery."
