...by saying that the former was only concerned with quality, the latter only with quantity, mistook cause for effect. - Immanuel Kant

All false art, all vain wisdom, lasts its time but finally destroys itself, and its highest culture is also the epoch of its decay.

Since the human race's natural end is to make steady cultural progress, its moral end is to be conceived as progressing toward the better. And this progress may well be occasionally interrupted, but it will never be broken off.

The more one presupposes that his own power will suffice him to realize what he desires the more practical is that desire. When I treat a man contemptuously, I can inspire him with no practical desire to appreciate my grounds of truth. When I treat any one as worthless, I can inspire him with no desire to do right.
