Context

“that something was lacking, that a tremendous void encircled man—he did not know how to justify himself, to explain himself, to affirm himself, he suffered from the problem of his own meaning. He suffered also in other ways, he was in the main a diseased animal; but his problem was not suffering itself, but the lack of an answer to that crying question, "To what purpose do we suffer?" Man, the bravest animal and the one most inured to suffering, does not repudiate suffering in itself: he wills it, he even seeks it out, provided that he is shown a meaning for it, a purpose of suffering. Not suffering, but the senselessness of suffering was the curse which till then lay spread over humanity—and the ascetic ideal gave it a meaning!” source
