The fourth chapter completes the account of bodily valuing by treating its second dimension: how we value in our “affects.” In these we feel the world’s impacts upon us and evaluate, in this feeling, how they strengthen or weaken us. Here we value not by steering toward goods (as in our drives), but reactively and retrospectively. These feelings serve as signs in a different way: as signs of how we have been growing—or declining. This backward turn in our affects opens up a great problem for Nietzsche, here called his “problem of the past.” We humans are unhealthily preoccupied with our past, as he argues in his critiques of memory, history, ressentiment, and guilt. Our affectivity also raises the problem of suffering, whose felt judgment against life Schopenhauer uses to ground pessimism—a conclusion that Nietzsche denies and reverses: we are to embrace life even in its tragic aspect.
