Abstrakt:
The subject of the thesis revolves around the research concerning the motifs of good and evil in Tolkien's works and their comparison and applicability to established systems of philosophy. Each individual element of the motifs is analyzed according to three prevailing theories of ethics identifiable in the writings: Manichaeism, Augustinian and Boethian approach to morality, and Aristotle's virtue ethics. Based on the results, the implementation of moral themes is evaluated in regards to the complementarity of its elements.
