humanism n.

1580s, "student of the classical humanities, one accomplished in literature and classical culture," from French humaniste (16c.), formed on model of Italian umanista "student of human affairs or human nature," coined by Italian poet Lodovicio Ariosto (1474-1533), from Latin humanus "human" (see human (adj.).

In this use, the original notion appears to be "human" as opposed to "divine," that is, a student of the human achievements of the pre-Christian authors and philosophers, as opposed to the theological studies of the divines. As "this new-old learning had, or was credited with, a tendency to loosen the hold of the Church upon men's beliefs," humanist also gradually came to mean "free-thinker" [Fowler]. Philosophical sense is from 1903, from Comte's Religion of Humanity (compare humanism), unconnected to the two earlier meanings, "though accidentally near one of them in effect" [Fowler].

mid-15c., humain, humaigne, "human," from Old French humain, umain (adj.) "of or belonging to man" (12c.), from Latin humanus "of man, human," also "humane, philanthropic, kind, gentle, polite; learned, refined, civilized." This is in part from PIE *(dh)ghomon-, literally "earthling, earthly being," as opposed to the gods (from root *dhghem- "earth"), but there is no settled explanation of the sound changes involved. Compare Hebrew adam "man," from adamah "ground." Cognate with Old Lithuanian žmuo (accusative žmuni) "man, male person."

Human interest is from 1824. Human rights attested by 1680s; human being by 1690s. Human relations is from 1916; human resources attested by 1907, American English, apparently originally among social Christians and based on natural resources. Human comedy "sum of human activities" translates French comédie humaine (Balzac); see comedy.
