[[File:Aristotle_Altemps_Inv8575.jpg|Aristotle Altemps Inv8575|thumb]] '''Physis''' ([[Greek language|Greek]]: φύσις phusis) is a term used in [[philosophy]], especially in [[Ancient Greek philosophy|ancient Greek philosophy]], which refers to the natural order, the inherent characteristics of an entity, or the universe itself. The concept of physis plays a central role in the works of pre-Socratic philosophers, as well as in the philosophies of [[Plato]] and [[Aristotle]]. It is often contrasted with [[nomos]] (νόμος), meaning law, custom, or convention. The exploration of physis involves understanding the principles or the essence of beings and the natural world, seeking to explain their origin, growth, and change in a manner that is independent of human conventions.

==Etymology and Historical Background==
The word 'physis' originates from the Greek verb φύω (phuō), meaning "to grow", "to produce", or "to bring forth". In ancient Greek thought, physis referred to the innate nature of something, the way it grows and evolves by itself. This concept was integral to the philosophical inquiries of the [[Pre-Socratic philosophy|Pre-Socratics]], who sought to explain the cosmos and the nature of being without resorting to mythological explanations. For these thinkers, understanding physis was key to understanding the world.

==Physis in Pre-Socratic Philosophy==
In Pre-Socratic philosophy, physis was a central theme as philosophers sought to identify the fundamental substance or principle (archê) that constitutes the essence of the natural world. For example, [[Thales]] proposed that water is the physis of all things, while [[Anaximander]] suggested the apeiron (the boundless or the indefinite) as the underlying principle. [[Heraclitus]] emphasized change and conflict within the physis, famously stating that "everything flows" (panta rhei) and highlighting fire as the fundamental element.

==Physis in Classical Philosophy==
[[Plato]] and [[Aristotle]] further developed the concept of physis, integrating it into their philosophical systems. Plato, in his dialogues, often contrasts physis with techne (τέχνη), or art/craft, to explore the ideas of naturalness versus artificiality. Aristotle provided a more systematic treatment of physis in his works, particularly in "Physics" and "Metaphysics". He defined physis as the principle of motion and rest in that to which it belongs primarily, in virtue of itself and not accidentally. Aristotle's analysis of physis includes his theory of four causes (material, formal, efficient, and final) and his distinction between potentiality (dunamis) and actuality (energeia).

==Physis and Nomos==
The distinction between physis and nomos is a significant theme in ancient Greek thought, especially in the context of ethics and political philosophy. This dichotomy addresses the question of what is natural and inherent versus what is conventional or constructed by human society. The Sophists, such as [[Protagoras]] and [[Gorgias]], often argued that laws and moral values are not natural but are agreements made by societies. In contrast, philosophers like [[Socrates]], Plato, and Aristotle contended that there is a natural basis for ethics and political organization, which can be understood through rational inquiry.

==Legacy==
The concept of physis has had a lasting impact on the development of Western philosophy, influencing not only ancient philosophical thought but also modern and contemporary discussions in metaphysics, ethics, and political philosophy. The exploration of natural principles, the essence of beings, and the distinction between the natural and the artificial continue to be relevant in philosophical debates.
