For example:

MIND -
Middle English, from Old English gemynd; akin to Old High German gimunt memory, Latin ment-, mens mind, monēre to remind, warn, Greek menos spirit, mnasthai, mimnēskesthai to remember

Apparently, originally, the word mind was not seen as a sort of substance. It was used as a metaphor for some of the processes of the brain.

power
1297, from Anglo-Fr. pouair, O.Fr. povoir, noun use of the infinitive in O.Fr., “to be able,” earlier [i]podir /i, from V.L. *potere, from L. potis “powerful” (see potent). Meaning “a state or nation with regard to international authority or influence” is from 1726. The verb meaning “to supply with power” is recorded from 1898. Powerful is c.1400. Powerhouse “building where power is generated” is from 1881; fig. sense attested from 1915. Power-broker (1961) said to have been coined by T.H. White in ref. to the 1960 U.S. presidential election. Phrase the powers that be is from Rom. xiii.1. As a statement wishing good luck, more power to (someone) is recorded from 1842.

metaphysics
1387, “branch of speculation which deals with the first causes of things,” from M.L. metaphysica, neut. pl. of Medieval Gk. (ta) metaphysika, from Gk. ta meta ta physika “the (works) after the Physics,” title of the 13 treatises which traditionally were arranged after those on physics and natural sciences in Aristotle’s writings. The name was given c.70 B.C.E. by Andronicus of Rhodes, and was a ref. to the customary ordering of the books, but it was misinterpreted by L. writers as meaning “the science of what is beyond the physical.” Hence, metaphysical came to be used in the sense of “abstract, speculative” (e.g. by Johnson, who applied it to certain 17c. poets, notably Donne and Cowley, who used “witty conceits” and abstruse imagery). The word originally was used in Eng. in the singular; plural form predominated after 17c., but singular made a comeback late 19c. in certain usages under Ger. influence.

This reflects the Dutch proverb, “The wish is the father of the thought.”
