Physis
Physis (/ˈfaɪˈsɪs/; Ancient Greek: φύσις [pʰýsis]; pl. physeis, φύσεις) is a Greek philosophical, theological, and scientific term, usually translated into English—according to its Latin translation "natura"—as "nature". The term originated in ancient Greek philosophy, and was later used in Christian theology and Western philosophy. In pre-Socratic usage, physis was contrasted with νόμος, nomos, "law, human convention". Another opposition, particularly well-known from the works of Aristotle, is that of physis and techne – in this case, what is produced and what is artificial are distinguished from beings that arise spontaneously from their own essence, as do agents such as humans. Further, since Aristotle the physical (the subject matter of physics, properly τὰ φυσικά "natural things") has been juxtaposed to the metaphysical.
The Greek word physis can be considered the equivalent of the Latin natura. The abstract term physis is derived from the verb phyesthai/phynai, which means “to grow”, “to develop”, “to become” (Frisk 2006: 1052; Caspers 2010b: 1068). In ancient philosophy one also finds the noun "physis" referring to the growth expressed in the verb phyesthai/phynai and to the origin of development (Plato, Menexenos 237a; Aristotle, Metaphysics 1014b16–17). In terms of linguistic history, this verb is related to forms such as the English “be”, German sein or Latin esse (Lohmann 1960: 174; Pfeifer 1993: 1273; Beekes 2010: 1598). In Greek itself, the aorist (a verbal aspect) of “to be” can be expressed with forms of phynai. With regard to its kinship with “being” and the basic meaning of the verb stem phy- or bhu- (“growing”), there has long been criticism of the conventional translation of the word "physis" with “nature”. With the Latin natura, which for its part goes back to the verb nasci (“to be born”), one transfers the basic word "physis" into a different sphere of association. In this way, the emerging growth (of plants, for instance) is transferred into the realm of being born.
The word φύσις is a verbal noun based on φύειν "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.
In pre-Socratic philosophy, beginning with Heraclitus, physis 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".
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. The contrast of physis vs. nomos could be applied to any subject, much like the modern contrast of "nature vs. nurture".
In book 10 of Laws, Plato criticizes those who write works peri physeōs. 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.
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.
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." 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." 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).
