Painting.... turned to the design of purely abstract volumetric forms... Since the leading exponent of the color theory was a painter (Malevich), he failed to recognize the objective reality of the world [in architecture!]. Because he always looked at it only through his own eyes, he remained trapped in a world devoid of real objects. The broader implications of this had to be developed by us, the architects.
