To allow only the kind of art that the average man understands is the worst small-mindedness and the murder of mind and spirit. It is my conviction that the intellect can be certain that in doing what most disconcerts the crowd, in pursuing the most daring, unconventional advances and explorations, it will in some highly indirect fashion serve man - and in the long run, all men.

I tell them that if they will occupy themselves with the study of mathematics they will find in it the best remedy against the lusts of the flesh.

We do not fear being called meticulous, inclining as we do to the view that only the exhaustive can be truly interesting.

Even in a personal sense, after all, art is an intensified life. By art one is more deeply satisfied and more rapidly used up. It engraves on the countenance of its servant the traces of imaginary and intellectual adventures, and even if he has outwardly existed in cloistral tranquility, it leads in the long term to overfastidiousness, over-refinement, nervous fatigue and overstimulation, such as can seldom result from a life of the most extravagant passions and pleasures.

Time cools, time clarifies; no mood can be maintained quite unaltered through the course of hours.

Only love, and not reason, yields kind thoughts.
