The word „morals”, although frequently employed both in colloquial and scientific language, lacks
clear and definite meaning. The ambiguity and incoherence o f the concept present difficulties for both
scholars who attempt to precisely delineate the subject o f their investigation and normative ethicists who
aim at demonstrating what is good in the moral sense. The author of the paper discusses various modes o f
comprehending morals and presents attempts at definining the concept. After introducing various
definitions o f morals (in respect o f form as well as content, and also analytical, synthetic and regulating
ones) she points to the usefulness o f the definitions o f morals and methodological knowledge in both
research and moral choices.
