Freedom is the fundamental character of the will, as weight is of matter... That which is free is the will. Will without freedom is an empty word.

Children are potentially free and their life directly embodies nothing save potential freedom. Consequently they are not things and cannot be the property either of their parents or others.

Public opinion contains all kinds of falsity and truth, but it takes a great man to find the truth in it. The great man of the age is the one who can put into words the will of his age, tell his age what its will is, and accomplish it. What he does is the heart and the essence of his age, he actualizes his age. The man who lacks sense enough to despise public opinion expressed in gossip will never do anything great.

The valor that struggles is better than the weakness that endures.

Philosophy is by its nature something esoteric, neither made for the mob nor capable of being prepared for the mob.

It is because the method of physics does not satisfy the comprehension that we have to go on further.

Philosophy is the history of philosophy.
