It seems that the academic community is not interested in any branch of philosophy more than in ethics, the philosophy of morality. With the more pronounced questions of 21st century culture, the question of human action precisely in the context of the creation of “good or evil” is now becoming a burning issue, leading to contradictory scientific analyses and interpretations. We constantly discuss the ethics or lack of ethics in the world around us, too often only superficially understanding or experiencing this concept. In art and literature, it is the development of contemporary literary theories that contributes to the more intensive development of ethical criticism and to interdisciplinary links between philosophy and literary science. This paper, through various critical approaches, discusses the role of ethics and ethical criticism, aesthetics and ideology in children’s literature and critically analyses the positive and negative aspects of these phenomena.
