 A thinker is now that being in whom the impulse for truth and those life-preserving errors now clash for their first fight, after the impulse for truth has proved to be also a life-preserving power. Compared to the significance of this fight, everything else is a matter of indifference: the ultimate question about the conditions of life has been posed here, and we confront the first attempt to answer the question by experiment. To what extent can truth endure incorporation? That is the question; that is the experiment. (GS 110)
