Physis

Physis (φύσις) is an ancient Greek term encompassing the concept of nature, encompassing the inherent qualities and processes of the natural world. It refers to the intrinsic source of development and change within living beings and inanimate objects, distinguishing them from artificial creations. physis implies a self-regulating, dynamic force or principle of growth, generation, and decay. It signifies not just the observable physical world but also the underlying principles governing its existence and transformation. Understanding physis was central to early Greek philosophical inquiries into the fundamental nature of reality and the origins of the cosmos, including the origin and development of life and the universe. It contrasted sharply with the concept of *nomos*, which represented human-made laws, conventions, and customs.
