Abstract

Karol Wojtyła understood that the turn to the subject had beneficially augmented traditional metaphysics by revealing the uniqueness of each person. Nevertheless, he also knew that for those investigations into personhood to resist devolving into mere relativism, the analysis had to be grounded in the metaphysical principles of Thomism. One contemporary illustration of an ungrounded subjectivism is the rise of identitarianism; that is, the idea that people can choose their own identity based on a peculiar property as distinct from our common human nature. In this paper, I will examine both the Thomistic metaphysical and phenomenological personalist bases for critiquing identitarianism. I will argue that the analogy of being, distinguishing substance from dependent modes of being, is the necessary metaphysical foundation for the personalist integration of actions in a subject who, while unique, must be recognized primarily as an instance of a common human nature.
