In my article, I briefly present the axioms of Leon Chwistek’s theory of manifold reality (TMR). This theory is the basis of his theory of art (TMRA). The aim of my article is to present and discuss psychological foundations of Chwistek’s theory of art. In particular, I present and discuss: (1) two meanings of the notion “work of art” derived on the basis of two relations: work – experience of enthusiasm, and work – aesthetic experience; (2) two meanings of the notion “content of the work of art”; (3) relations between the axioms (beliefs) of TMR and means of every type of art contained in TMRA.
