A man can be himself only so long as he is alone, and if he does not love solitude, he will not love freedom, for it is only when he is alone that he is really free.
It is only a man's own fundamental thoughts that have truth and life in them. For it is these that he really and completely understands. To read the thoughts of others is like taking the remains of someone else's meal, like putting on the discarded clothes of a stranger.
Men are by nature merely indifferent to one another; but women are by nature enemies.
The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.
