Since Copernicus, man seems to have got himself on an inclined plane-now he is slipping faster and faster away from the center into-what? into nothingness? into a 'penetrating sense of his nothingness?' ... all science, natural as well as unnatural-which is what I call the self-critique of knowledge-has at present the object of dissuading man from his former respect for himself, as if this had been but a piece of bizarre conceit.

The secret of realizing the greatest fruitfulness and the greatest enjoyment of existence is: to live dangerously! Build your cities on the slopes of Vesuvius! Send your ships out into uncharted seas! Live in conflict with your equals and with yourselves! Be robbers and ravagers as soon as you ca not be rulers and owners, you men of knowledge! The time will soon past when you could be content to live concealed int he woods like timid deer!

Human, all too human.
