Three squares that changed the world. Russian Suprematism by K. Malevich in the intersection with the philosophy of ideas of Russian cosmism by N. Fedorov: Historical and philosophical analysis.

The purpose of this study is to analyse the relationship between the two leading movements in the art of the early twentieth century, known as the "Russian avant-garde", and the philosophical trend known as "Russian cosmism". These two currents epitomise cutting-edge ideas and are of interest to the modern world. Special attention is paid to the relevance of early twentieth-century Russian philosophical thought, with its cutting-edge ideas that are still relevant and important to modern society.
