Organic

Origin

1350–1400; ME: pertaining to an organ of the body < L organicus by or employing a mechanical device, instrumental < Gk organikós equiv. to órgan(on) organ + -ikos -ic 

"Its source is the Greek organon, which comes from the same root as erg, “work”, and which had the linked meaning of “implement, instrument, tool”, that is, something one works with. It could also refer to a part of the body in the restricted sense of one that’s an instrument to do something with. It’s the name given to Aristotle’s treatise on logic (in the sense of the instrument of all reasoning). The word was used in its Latin form by Francis Bacon in 1620 as the title of his philosophical treatise Novum Organun, “new instrument”, which set out a new set of principles for scientific investigation" http://www.worldwidewords.org/topicalwords/tw-org1.htm
