El Lissitsky Quote

The path of the PROUN does not lie within the narrowly limited, fragmented, and isolated scientific disciplines — the builder consolidates them all together in his own experimental investigation. The path of the PROUN is not the incoherent approach of separate scientific disciplines, theories, and systems, but is rather the straightforward path of learned influence over reality.
