Man is nothing else but what he makes of himself.
What is life but an unpleasant interruption to a peaceful nonexistence.
The consciousness that says 'I am' is not the consciousness that thinks.
We make our own hell out of the people around us.
Existence is not something which lets itself be thought of form a distance; it must invade you suddenly, master you, weigh heavily on your heart like a great motionless beast - or else there is nothing at all.
The individual's duty is to do what he wants to do, to think whatever he likes, to be accountable to no one but himself, to challenge every idea and every person.
