Arthur Schopenhauer
All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.
Each day is a little life: every waking and rising a little birth, every fresh morning a little youth, every going to rest and sleep a little death.
Opinion is like a pendulum and obeys the same law. If it goes past the centre of gravity on one side, it must go a like distance on the other; and it is only after a certain time that it finds the true point at which it can remain at rest.
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.
They tell us that suicide is the greatest piece of cowardice... that suicide is wrong; when it is quite obvious that there is nothing in the world to which every man has a more unassailable title than to his own life and person.
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.
The doctor sees all the weakness of mankind; the lawyer all the wickedness, the theologian all the stupidity.
