Nobody can claim himself to be practically proficient in a science and yet disdain its theory without revealing himself to be an ignoramus in his are… - Immanuel Kant

Man's greatest concern is to know how he shall properly fill his place in the universe and correctly understand what he must be in order to be a man.

Wer sich aber zum Wurm macht, kann nachher nicht klagen, dass er mit Füßen getreten wird.

The master is himself an animal, and needs a master. Let him begin it as he will, it is not to be seen how he can procure a magistracy which can maintain public justice and which is itself just, whether it be a single person or a group of several elected persons. For each of them will always abuse his freedom if he has none above him to exercise force in accord with the laws. The highest master should be just in himself, and yet a man. This task is therefore the hardest of all; indeed, its complete solution is impossible, for from such crooked wood as man is made of, nothing perfectly straight can be built. That it is the last problem to be solved follows also from this: it requires that there be a correct conception of a possible constitution, great experience gained in many paths of life, and — far beyond these — a good will ready to accept such a constitution. Three such things are very hard, and if they are ever to be found together, it will be very late and after many vain attempts.
