Ideas, as distinguished from events, are never unprecedented.

Predictions of the future are never anything but projections of present automatic processes and procedures, that is, of occurrences that are likely to come to pass if men do not act and if nothing unexpected happens; every action, for better or worse, and every accident necessarily destroys the whole pattern in whose frame the prediction moves and where it finds its evidence.

The history of humanity is not a hotel where someone can rent a room whenever it suits him; nor is it a vehicle which we board or get out of at random. Our past will be for us a burden beneath which we can only collapse for as long as we refuse to understand the present and fight for a better future. Only then — but from that moment on — will the burden become a blessing, that is, a weapon in the battle for freedom.

The sad truth is that most evil is done by people who never make up their minds to be good or evil.

In order to go on living one must try to escape the death involved in perfectionism.

The human condition is such that pain and effort are not just symptoms which can be removed without changing life itself; they are the modes in which life itself, together with the necessity to which it is bound, makes itself felt. For mortals, the easy life of the gods would be a lifeless life.

Ideas, as distinguished from events, are never unprecedented.
