ABSTRACT
This sequel to "Man and the Biosphere" is an account of the origins and development of a cultural, social energetic and systems theoretical contribution to critical Marxism. It examines: the intellectual contributions of the Russian philosophers, A.A. Bogdanov and A.I. Bukharin; Bogdanov's and Bukharin's contributions as a search for a unity of scientific knowledge; and a paradigmatic change from a closed mechanical system to an open systems paradigm.
