The paper presents the idea of perfectiorism in the philosophy of Karol Wojtyła – a man becomes morally better, but not perfect, by every good action. The article has three parts: 1) the outline of Wojtyła’s philosophical anthropology: a man is a morally subject, because every man is a acting being; every deed reveals not only person but also basic structure of the man (subjective structure – consciousness, causality, self-determination, responsibility and objective structure – soul, psyche, body, participation); 2) the possibility of perfectiorism in the classical philosophy of being (Aristotle and Thomas Aquinas): a good is identical with the aim of the striving of the being; the aim is adequate to the nature of the being and improves it; the perfection is definited by the way of being and the substancial form; the purpose of every being should be the actualization of the possibilities of the nature; 3) the impossibility of the perfectiorism in the philosophy of consciousness (I. Kant and M. Scheler): a mind has been separated from the whole being and a good has been reduced to the experience of the consciousness (Kant’s categorical imperative and Scheler’s experience of values); the consequence is the isolation the experience from the action.
