First Published in 1972, presents Ervin Laszlo’s first comprehensive volume on the subject. It argues for a systematic and constructive inquiry into natural phenomenon on the assumption of general order in nature. Laszlo says systems philosophy reintegrates the concept of enduring universals with transient processes within a non-bifurcated, hierarchically differentiated realm of invariant systems, as the ultimate actualities of self-structuring nature. He brings themes like the promise of systems philosophy; theory of natural systems; empirical interpretations of physical, biological, and social systems; frameworks for philosophy of mind, philosophy of nature, ontology, epistemology, metaphysics and normative ethics, to showcase the timeliness and necessity of a return from analytic to synthetic philosophy. This book is an essential read for any scholar and researcher of philosophy, philosophy of science and systems theory.
