Context

“He should not repudiate them once he has performed them. Pangs of conscience are indecent. 11 Can a donkey be tragic?—To perish beneath a load that one can neither bear nor throw off? This is the case of the Philosopher. 12 If a man knows the wherefore of his existence, then the manner of it can take care of itself. Man does not aspire to happiness; only the Englishman does that. 13 Man created woman—out of what? Out of a rib of his god,—of his "ideal." 14 What? Art thou looking for something? Thou [Pg 3] wouldst fain multiply thyself tenfold, a hundredfold?” source
