The paper discusses selected topics in moral philosophy of Professor Bogusław Wolniewicz. His overall approach is marked by intellectual independence and analytic treatment of moral issues. The theory of values that he has endorsed can be described as a moderate non-religious absolutism based on weak metaphysical principles. Although in general his normative position can be assimilated to the views of an enlightened liberal, it also clashes with that position insofar as he proclaimed the existence of ontological evil and supported legitimacy of death penalty.
