No one is accountable for existing at all, or for being constituted as he is, or for living in the circumstances and surroundings in which he lives. The fatality of his nature cannot be disentangled from the fatality of all that which has been and will be.

We invented the concept 'purpose': in reality purpose is lacking...One is necessary, one is a piece of fate, one belongs to the whole, one is in the whole--there exists nothing which could judge, measure, compare, condemn our being, for that would be to judge, measure, condemn the whole...
