The Only Genuine Ideas

Friedrich Nietzsche says we have burned our bridges and taken to ship (link). Evidently for this man, taking to ship is only the beginning:

And this is the simple truth—that to live is to feel oneself lost—he who accepts it has already begun to find himself, to be on firm ground. Instinctively, as do the shipwrecked, he will look around for something to which to cling, and that tragic, ruthless glance, absolutely sincere, because it is a questioning of his salvation, will cause him to bring order into the chaos of his life. These are the only genuine ideas; the ideas of the shipwrecked. All the rest is rhetoric, posturing, farce. He who does not really feel himself lost is lost without remission; that is to say, he never finds himself, never comes up against his own reality.
