Reason looks at necessity as the basis of the world; reason is able to turn chance in your favor and use it. Only by having reasonremain strong and unshakable can we be called a god of the earth.

Only law can give us freedom.

Who is the wisest man? He who neither knows or wishes for anything else than what happens.

If we take people only as they are, then we make them worse; if we treat them as if they were what they should be, then we bring them to where they can be brought.

The useful may be trusted to further itself, for many produce it and no one can do without it; but the beautiful must be specially encouraged, for few can present it, while yet all have need of it.

Someday someone will write a pathology of experimental physics and bring to light all those swindles which subvert our reason, beguile our judgement and, what is worse, stand in the way of any practical progress. The phenomena must be freed once and for all from their grim torture chamber of empiricism, mechanism, and dogmatism; they must be brought before the jury of man's common sense.

What a torment it is to see so much loveliness passing and repassing before us, and yet not dare to lay hold of it!
