In this essay I discuss a passage from William Styron’s memoir of his long struggle with chronic severe depression, from the standpoint of a Spinozian understanding of agency and self-worth. In this passage Styron relates how in hearing a piece of music he was abruptly struck by a recollection of “all the joys [his] house had known” and how this brought a realization that it would be wrong for him to kill himself: wrong because it would be an abandonment of (...) those who had shared in those joys and a “desecration” of himself. He tells how this realization led him to admit himself to hospital for treatment and thereby to a slow and difficult recovery. This, I propose, illustrates the Spinozian idea that the value of an individual life is properly understood in terms of that individual’s participation in the actualization of a shared value and that individual agency is empowered by the knowledge of such value.
