Physis (Greek: φύσις phusis) is a Greek theological, philosophical, and scientific term usually translated into English as "nature".

The term is central to Greek philosophy, and as a consequence to Western philosophy as a whole. In pre-Socratic usage, phusis was contrasted with νόμος, nomos, "law, human convention." Since Aristotle, however, the physical (the subject matter of physics, properly τὰ φυσικά "natural things") has more typically been juxtaposed to the metaphysical.[1]

Pre-socratic usage[edit]

The word φύσις is a verbal noun based on φύω "to grow, to appear" (cognate with English "to be"). In Homeric Greek it is used quite literally, of the manner of growth of a particular species of plant.[2]

In pre-Socratic philosophy, beginning with Heraclitus, phusis in keeping with its etymology of "growing, becoming" is always used in the sense of the "natural" development, although the focus might lie either with the origin, or the process, or the end result of the process. There is some evidence that by the 6th century BC, beginning with the Ionian School, the word could also be used in the comprehensive sense, as referring to "all things", as it were "Nature" in the sense of "Universe".[3]

In the Sophist tradition, the term stood in opposition to nomos (νόμος), "law" or "custom", in the debate on which parts of human existence are natural, and which are due to convention.[4] The contrast of phisis vs. nomos could be applied to any subject, much like the modern contrast of "nature vs. nurture".

In Plato's Laws[edit]

In book 10 of Laws, Plato criticizes those who write works peri phuseōs. The criticism is that such authors tend to focus on a purely "naturalistic" explanation of the world, ignoring the role of "intention" or technē, and thus becoming prone to the error of naive atheism. Plato accuses even Hesiod of this, for the reason that the gods in Hesiod "grow" out of primordial entities after the physical universe had been established.[5]

"Because those who use the term mean to say that nature is the first creative power; but if the soul turns out to be the primeval element, and not fire or air, then in the truest sense and beyond other things the soul may be said to exist by nature; and this would be true if you proved that the soul is older than the body, but not otherwise."

— Plato's Laws, Book 10(892c) – translation by Benjamin Jowett

Aristotle[edit]

Aristotle sought out the definition of "physis" to prove that there was more than one definition of "physis", and more than one way to interpret nature. "Though Aristotle retains the ancient sense of "physis" as growth, he insists that an adequate definition of "physis" requires the different perspectives of the four causes (aitia): material, efficient, formal, and final."[6] Aristotle believed that nature itself contained its own source of matter (material), power/motion (efficiency), form, and end (final). A unique feature about Aristotle's definition of "physis" was his relationship between art and nature. Aristotle said that "physis" (nature) is dependent on techne (art). "The critical distinction between art and nature concerns their different efficient causes: nature is its own source of motion, whereas techne always requires a source of motion outside itself."[6] What Aristotle was trying to bring to light, was that art does not contain within itself its form or source of motion. Consider the process of an acorn becoming an oak tree. This is a natural process that has its own driving force behind it. There is no external force pushing this acorn to its final state, rather it is progressively developing towards one specific end (telos).

Biblical usage[edit]

Though φύσις was often used in Hellenistic philosophy, it is used only 14 times in the New Testament (10 of those in the writings of Paul).[7] Its meaning varies throughout Paul's writings.[8] One usage refers to the established or natural order of things, as in Romans 2:14 where Paul writes "For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law."[9][10] Another use of φύσις in the sense of "natural order" is Romans 1:26 where he writes "the men likewise gave up natural relations with women and were consumed with passion for one another".[11][12] In 1 Corinthians 11:14, Paul asks "Does not nature itself teach you that if a man wears long hair it is a disgrace for him?"[13][14]

This use of φύσις as referring to a "natural order" in Romans 1:26 and 1 Corinthians 11:14 may have been influenced by Stoicism.[14] The Greek philosophers, including Aristotle and the Stoics are credited with distinguishing between man-made laws and a natural law of universal validity,[15] but Gerhard Kittel states that the Stoic philosophers were not able to combine the concepts of νόμος (law) and φύσις (nature) to produce the concept of "natural law" in the sense that was made possible by Judeo-Christian theology.[16]

As part of the Pauline theology of salvation by grace, Paul writes in Ephesians 2:3 that "we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. In the next verse he writes, "by grace you have been saved." [17][18]

Usage in patristic theology[edit]

Theologians of the early Christian period differed in the usage of this term. In Antiochene circles, it connoted the humanity or divinity of Christ conceived as a concrete set of characteristics or attributes. In Alexandrine thinking, it meant a concrete individual or independent existent and approximated to hypostasis without being a synonym.[19] While it refers to much the same thing as ousia it is more empirical and descriptive focussing on function while ousia is metaphysical and focuses more on reality.[20] Although found in the context of the Trinitarian debate, it is chiefly important in the Christology of Cyril of Alexandria.[20]

Modern usage[edit]

The Greek adjective phusikos is represented in various forms in modern English: As physics "the study of nature", as physical (via Middle Latin physicalis) referring both to physics (the study of nature, the material universe) and to the human body.[21] The term physiology (physiologia) is of 16th-century coinage (Jean Fernel). The term physique, for "the bodily constitution of a person", is a 19th-century loan from French.

In medicine the suffix -physis occurs in such compounds as symphysis, epiphysis, and a few others, in the sense of "a growth". The physis also refers to the "growth plate", or site of growth at the end of long bones.
