In my work I present a version of the semantics of relative preference for the logic of ought-to-be and for the logic of ought-to-do. I draw the philosophical inspirations for this semantics from Elzenberg’s axiological papers. In the semantics of relative preference I check which deontic principles are valid—especially those which Wolniewicz extracted from Elzenberg’s papers. I also check if it is possible in this semantics to fulfil the condition of the moral dilemma.
