Rooted in the fact–value dichotomy of the modern scientific outlook, psychology tends to render “ought” as distinguishable from and additional to “is.” The purpose of this article, however, is to disclose an “oughtness” at the center of human existence by which human beings inevitably live and suffer. In the first part, psychology’s neglect of oughtness is tracked down through significant albeit different theoretical strands. Second, through a threefold argument entailing (a) the other, (b) language, and (c) the self, it is revealed how people’s concrete lived lives as well as the very formation of a subject are incomprehensible without the oughtness of existence. Finally, the relation between suffering and oughtness is spelled out. Due to the oughtness of existence, guilt and inadequacy enter into the human life.
