The issue of autonomy seems to play a very central and fundamental role in contemporary medical ethics. However, it should be emphasized, that there is no agreement on how the concept of autonomy ought to be understood. Although as the main intellectual framework to describe the meaning of "autonomy" is the use of philosophical system of John St. Mill or Immanuel Kant, one could identify the tendency to redefine the concept under study. The aim of this article was to find out if the philosophy of Karol Wojtyla could provide--interesting from the bioethical point of view--insights into understanding of the idea of autonomy. The Wojtyla's critique of Kant's and Mill's understanding of autonomy was shortly described and the main elements of Wojtyla's concept of autonomy were analyzed. On the basis of these considerations it was assumed that philosophical background of Wojtyla is so different from those which are used in the contemporary, especially so called Anglo-American, bioethics that introducing it "elements" of his thinking would lead to misunderstandings and indeed even serious errors. On the other hand, however, philosophical works of Wojtyla seems to be very influential in developing 'personalistic' bioethics. But this bioethics could be accepted only by people who share Wojtyla's ontological and probably also theological or religious assumptions.
