Origin and meaning of value
c. 1300, "price equal to the intrinsic worth of a thing;" late 14c., "degree to which something is useful or estimable," from Old French value "worth, price, moral worth; standing, reputation" (13c.), noun use of fem. past participle of valoir "be worth," from Latin valere "be strong, be well; be of value, be worth" (from PIE root *wal- "to be strong"). The meaning "social principle" is attested from 1918, supposedly borrowed from the language of painting. Value judgment (1889) is a loan-translation of German Werturteil.

provincialism (n.)

1820 in the political sense, "local attachment as opposed to national unity," from provincial + -ism. Meaning "a certain narrowness of localism of thought or interest; lack of polish or enlightenment," reflecting manners or modes of a certain province or of provinces generally (as opposed to the big city or the capital) is by 1836. Sense of "a local word or usage or expression" is from 1770.

To me provincialism stood, and stands, for the sum-total of all false values; it is the estimation of people for what they have, or pretend to have, and not for what they are. Artificial classifications, rigid lines of demarkation that bear no relation whatsoever to intrinsic merit, seem to belong to its very essence, while contempt for intelligence, suspicion and fear of independent thought, appear to be necessary passports to provincial popularity.

proper (adj.)

c. 1300, propre, "adapted to some purpose, fit, apt; commendable, excellent" (sometimes ironic), from Old French propre "own, particular; exact, neat, fitting, appropriate" (11c.) and directly from Latin proprius "one's own, particular to itself," from pro privo "for the individual, in particular," from ablative of privus "one's own, individual" (see private (adj.)) + pro "for" (see pro-). Related: Properly; properness. As an adverb, "very exceedingly," from mid-15c., but since 19c. the use is considered vulgar.

From early 14c. as "belonging or pertaining to oneself; individual; intrinsic;" also as "pertaining to a person or thing in particular, special, specific; distinctive, characteristic;" also "what is by the rules, correct, appropriate, acceptable." From early 15c. as "separate, distinct; itself." Meaning "socially appropriate, decent, respectable" is recorded by 1704.

Proper name "name belonging to or relating to the person or thing in question, name given to an individual of a class for distinction from others of the same class" is from c. 1300, a sense also preserved in astronomical proper motion "change in the apparent places of a celestial object in the sky relative to other stars or planets" (c. 1300). Proper noun is from mid-15c.
