• conscience •
Pronunciation: kahn-chêns • Hear it!
Part of Speech: Noun (Mass, uncountable)
Meaning: That faculty of the human mind that guides our sense of morality, our sense of right and wrong.
Notes: It sometimes seems that conscience is an optional faculty of the human mind and that some people lack one. The word comes with two adjectives, conscienced "having a conscience" and conscienceless "not having one". The former may also be negated, unconscienced.
In Play: Our conscience is our knowledge of right and wrong: "Les Booker thought of publishing false tales about Penny Wise in the social media after she dumped him, but his conscience prevailed and he didn't." But some people seem to have none: "Buck Shott is a hitman who is devoid of conscience, remorse and compassion."
Word History: English took this word from Old French conscience, which inherited from Latin conscientia "joint knowledge, common knowledge", comprising con- "(together) with" + scien(t)s "knowledge, intelligence". Scien(t)s is the present participle used as a noun of scire "to know". Conscientia may have been a loan (part-by-part) translation of Greek syneidesis, made up of syn "(together) with" + eidesis "knowledge". If so this would suggest it comes from PIE weid- "to see, to know" underlying Sanskrit vetti "knows", Latin videre "to see", Armenian egit "found", Welsh gwyddor "science", Dutch weten "to know", German wissen "to know", English wit and wisdom, Norwegian vite "to know", Polish widzieć "to see", Russian videt' "to see", and Serbian videti "to see". Otherwise, if it comes from Latin scire, that suggests it comes from PIE skei- "to cut", a path that provides major semantic problems.
