All truths are erroneous. This is the very essence of the dialectical process: today's truths become errors tomorrow; there is no final number. This truth (the only one) is for the strong alone. Weak-nerved minds insist on a finite universe, a last number; they need, in Nietzsche's words, "the crutches of certainty". The weak-nerved lack the strength to include themselves in the dialectic syllogism.

It is an error to divide people into the living and the dead: there are people who are dead-alive, and people who are alive-alive. The dead-alive also write, walk, speak, act. But they make no mistakes; only machines make no mistakes, and they produce only dead things. The alive-alive are constantly in error, in search, in questions, in torment.
