"Be aware of this truth that the people on this earth could be joyous, if only they would live rationally and if they would contribute mutually to each others' welfare.This world is not a vale of sorrows if you will recognize discriminatingly what is truly excellent in it; and if you will avail yourself of it for mutual happiness and well-being.

"From this time on, the universe is built up into an aggregate of permanent objects connected by causal relations that are independent of the subject and are placed in objective space and time."
"The current state of knowledge is a moment in history, changing just as rapidly as the state of knowledge in the past has ever changed and, in many instances, more rapidly."
"To express the same idea in still another way, I think that human knowledge is essentially active."
"During the earliest stages the child perceives things like a solipsist who is unaware of himself as subject and is familiar only with his own actions."
