Abstract
The author's unified system concept" evolves as a result of a new approach to the unification of physics and biology. Phenomena can be regarded either as cyclical and recurrent or as unique and structural, but from a wider perspective, every event can be taken as a phase in a recurrent process. Such a relativity allows us to consider the universe as constituted by nothing but recurrent, self-maintaining processes, some being the objects of physics and others of biology but both united as processes in a totality. Of particular interest are the author's discussions of the dependence and independence of the organism on its surroundings and of the relation of the cyclical and the unique to time.--M. F.
