This article discusses the concept of boredom - an essential problem in philosophy, psychology and the history of literature - derived from the work of G. Flaubert, T. Mann and J. Brodsky. In the work of G. Flaubert (Madame Bovary), boredom is associated with aversion to the sensual dimension of life. The writer also establishes a close relationship between boredom, triviality and despair. T. Mann (Der Zauberberg) regards boredom as a pathological condition which, however, is a necessary stage in the individual development process leading to a fully independent personality. According to J. Brodsky, boredom is both a sickness of an existential nature and a specific state of sorrow embedded in the ontological order of the world, a state perceived from the perspective of infinite time.
