The subject of the analysis and interpretation in this article is Stanislaw Brzostowski's discourse, and his philosophical language as presented in his sketch entitled 'Epigenetic Theory of History' in particular. As seen in one of the many Brzozowski's treatises, the author shows the characteristic modes of the rhetorical organization of a text, the elements that affect argumentation, and the disquisition line. The scientific style of the sketch is also carefully analyzed since it proves to stem from taking a specific point of view in reality at the intersection of various languages in various epochs, peculiar to philosophy, criticism, sociology, or a manifesto. The analysis shows that significant and characteristic of the shaping of Brzozowski's language became not only factors connected with his outlook on life, but also a wide range of reading experience that influenced his thinking 'from the bottom' and generated the flow of his thoughts.
