“…it is the worst of all possible worlds. For possible means not what we may picture in our imagination, but what can actually exist and last. Now this world is arranged as it had to be if it were to be capable of continuing with great difficulty to exist; if it were a little worse, it would be no longer capable of continuing to exist. Consequently, since a worse world could no longer continue to exist, it is absolutely impossible; and so this world itself is the worst of all possible worlds.”

– Arthur Schopenhauer in On the vanity and suffering of life.
