“Their [philosophers] thinking is, in fact, far less a discovery than a re-recognizing, a remembering, a return and a home-coming to a far-off, ancient common-household of the soul, out of which those ideas formerly grew: philosophizing is so far a kind of atavism of the highest order.”

“I leaf through the ancient philosophers and find my newest discoveries there.”

“the greater the number of owners, the less the respect for common property. People are much more careful of their personal possessions than of those owned communally; they exercise care over common property only in so far as they are personally affected.”

“We should come home from far, from adventures, and perils, and discoveries every day, with new experience and character.”

“I am to cover the philosophical side of the debate and so far my only thought is that reading keeps you from going gaga.”

“Man is so complicated a machine that it is impossible to get a clear idea of the machine beforehand, and hence impossible to define it. For this reason, all the investigations have been vain, which the greatest philosophers have made à priori, that is to to say, in so far as they use, as it were, the wings of the spirit. Thus it is only à posteriori or by trying to disentangle the soul from the organs of the body, so to speak, that one can reach the highest probability concerning man's own nature, even though one can not discover with certainty what his nature is.”
