The monograph is devoted to the study of marginal phenomena of human existence. The main attention is paid to the analysis of the ontic-ontological aspects of marginality: the experience of the limit, extremes, being on the border, being in the center and on the periphery, as well as methods of transition, more broadly, interaction with the border. The monograph is addressed to philosophers, literary scholars, cultural scholars and everyone interested in philosophy. In format PDF A4 saved publishing layout of the book.
