Über sich selber lachen, wie man lachen müßte, um aus der ganzen Wahrheit heraus zu lachen, dazu hatten bisher die Besten nicht genug Wahrheitssinn und die Begabtesten viel zu weing Genie!  Es gibt vielleicht auch für das Lachen noch eine Zukunft! Dann, wenn der Satz "die Art ist alles, einer ist immer keiner"--sich der Menschheit einverleibt hat und jedem jederzeit der Zugang zu dieser letzten Befreiung und Unverantwortlichkeit offensteht. Vielleicht wird sich dann das Lachen mit der Weisheit verbündet haben, viellecht gibt es dann nur noch "fröhliche Wissenschaft."

To laugh at oneself as one would have to laugh in order to laugh out of the whole truth--to do that even the best so far lacked sufficient sense for the truth, and the most gifted had too little genius for that.  Even laughter may yet have a future.  I mean, when the proposition "the species is everything, one is always none" has become part of humanity, and this ultimate liberation and irresponsibility has become accessible to all at all times. Perhaps laughter will then have formed an alliance with wisdom, perhaps only "gay science" will then be left. 

To laugh at oneself as one would have to laugh in order to laugh from the whole truth--for that, not even the best have had enough sense of truth, and the most gifted have had far too little genius! Perhaps even laughter still has a future--when the proposition 'the species is everything, an individual is always nothing' has become part of humanity and this ultimate liberation and irresponsibility is accessible to everyone at all times. Perhaps laughter will then have formed an alliance with wisdom; perhaps only 'gay science' will remain.
