Deepens

"It is only great pain, that slow protracted pain which takes its time and in which we are, as it were, burned than with green wood, that compels us philosophers to descend into our ultimate depths and to put from us all trust, all that is good-hearted, palliated, gentle, average, wherein perhaps our humanity previously reposed. I doubt whether such pain "improves"-- but I do know it deepens us."  ~Friedrich Nietzsche
