ABSTRACT Perfectionism, the view according to which the good for an x is constituted by flourishing as an x, is a venerable account of the good, the popularity of which has only grown in recent decades. In this paper, I assess the merits of perfectionism in its traditional form, and argue in favor of a refinement. Specifically, I focus on traditional perfectionism’s account of the Central Axiological Category (CAC)---the kind ("x") that subjects fall into for the purposes of determining their (...) good. I argue that shifting our understanding of the CAC from the traditional human category to the category of valuer is faithful to the most significant perfectionist insights, and does not succumb to the numerous and substantial challenges for the traditional understanding.
