Pronunciation

  • 5th-century BC Attic: /pʰy.si.kós/[1]
  • 4th-century AD Koine: /ɸy.siˈkos/[1]
  • 10th-century Byzantine: /fy.siˈkos/[1]

Forms

φῠσῐκός (phusikós) m (feminine φῠσῐκή, neuter φῠσῐκόν); first/second declension[1]

Etymology

It is formed from Ancient Greek φύσις (phúsis, “nature”) + -ικός (-ikós), an adjective of the noun for “nature”.[1][2][3] The noun itself comes from φύω (phúō, “to grow, bring forth”).[4]

Earliest recorded meaning

LSJ notes that the word occurs only once in Xenophon and not at all in Plato.[5] In Xenophon's Memorabilia Socrates is asked whether courage can be taught or is “natural”, inborn.[5][6]

Semantic evolution

Aristotle made it a common word: “natural” as opposed to taught or conventional (natural justice against legal justice), “physical”, and “concerned with nature”, as in the phrase for natural science.[5][2] He calls the inquirers into nature, above all the Presocratic philosophers, simply hoi phusikoí, and the name τὰ φυσικά (tà phusiká) was given to his treatises on nature.[5][2] The Stoics, from Zeno on, divided philosophy into the physical, the ethical and the logical parts.[5]

Hellenistic prose used it of a simple, unaffected style (Dionysius of Halicarnassus) and of natural fortifications (Polybius).[5][2] In the New Testament, Paul sets the “natural” use of the body against what is contrary to nature, and Second Peter calls certain men creatures of instinct, born to be caught.[4][5] Late Greek used it for what works by the hidden laws of nature, that is, magic: Alexander of Tralles calls amulets “natural remedies”.[5]

Latin borrowed it as physicus.[7] English physics goes back through Latin to τὰ φυσικά, the title of Aristotle's work.[8] The word passed into Coptic, first recorded about 350.[9] Modern Greek φυσικός (fysikós) is learned and has taken senses from French naturel and English natural; the noun for a physicist follows French physicien, and φυσική (fysikí) “physics” follows French physique.[10]
