The object of research is the ontological constructs of good and evil in modern European philosophy. The aim of the study is the specifics of determining the planes of ontology of good and evil in anthropological, theological, ethical, axiological, epistemological constructs of Western European existential and postmodern philosophy Research methods were determined by the specifics of interdisciplinary problems that corresponded to the objectives of the study. The study of conceptual parallels of historical and philosophical aspects of the ontology of good and evil in Western European modern philosophy required the use of not only general scientific methods such as analysis and synthesis, abstraction, concretization, generalization, modeling, induction, and special methods of scientific and philosophical, cultural, historical and philosophical direction. Developed models of ontology of good and evil in Western European existential and postmodern philosophy is developed, which have a somewhat complex structure and illuminate the mechanisms of unity and equality of good and evil, are formed according to classical epistemological constructions of the tree of knowledge of good and evil under the influence of opportunities for human knowledge of the fundamental factors of existence and nothing, where the external filter (body, Other, death) has a polychrome echo in fears, anxieties, experiences, naming, values, etc.; ontological models are constantly changing under the influence of philosophical processes of understanding axiological, religious, ethical and other approaches. The practical significance of the dissertation is based on the clarification of scientific approaches that are important for further study of the problem of ontology of good and evil and its expansion beyond the study of a limited historical period and philosophical currents. The ontological aspects of the violation of dialogue and the limitation of cognition in determining the ontology of the body, Other, being, Nothing were clarified, being the filters of cognitive capabilities, as well as the main philosophical approaches to the study of ontology of good and evil by philosophers of the twentieth century were brought to light and which cannot be used as an algorithm to study this problem in the future.The sphere of application is education.
