“A new species of philosophers is coming up: I venture to baptize them with a name that is not free of danger. As I unriddle them, insofar as they allow themselves to be unriddled — for it belongs to their nature to want to remain riddles at some point — , these philosophers of the future may have a right, it might also be a wrong, to be called experimenters [Versucher, i.e. attempters]. This name itself is in the end a mere attempt [Versuch] and, if you will, a temptation [Versuchung].” — Nietzsche, Beyond Good and Evil
