I explore Leon Chwistek’s views on ontology and aesthetics through a philosophical analysis of his texts. I present and briefly discuss two main interpretations of Chwistek’s ontology, i.e. logical and epistemological, before analyzing Chwistek’s aesthetics to show how it may be based on his ontology. Furthermore, I link both interpretations to the problem of whether or not Chwistek’s four realities share a common domain; a problem which is associated with his aesthetics. Finally, I make suggestions regarding further research on his notion of transitional types of art and the corresponding realities.
