"ascription of human feelings to divine beings," 1640s, from Greek anthrōpopatheia "humanity," literally "human feeling," from anthrōpos "man, human" (see anthropo-) + -patheia, combining form of pathos "suffering, disease, feeling" (from PIE root *kwent(h)- "to suffer"). Related: Anthropopathic; anthropopathite; anthropopathically.
c. 1600, "natural aversion, hostile feeling toward," from Latin antipathia, from Greek antipatheia, abstract noun from antipathes "opposed in feeling, having opposite feeling; in return for suffering;" also "felt mutually," from anti "opposite, against" (see anti-) + pathein "to suffer, feel" (from PIE root *kwent(h)- "to suffer").
An abuse has crept in upon the employment of the word Antipathy. ... Strictly it does not mean hate,—not the feelings of one man set against the person of another,—but that, in two natures, there is an opposition of feeling. With respect to the same object they feel oppositely. [Janus, or The Edinburgh Literary Almanack, 1826]
1908, modeled on German Einfühlung (from ein "in" + Fühlung "feeling"), which was coined 1858 by German philosopher Rudolf Lotze (1817-1881) as a translation of Greek empatheia "passion, state of emotion," from assimilated form of en "in" (see en- (2)) + pathos "feeling" (from PIE root *kwent(h)- "to suffer"). A term from a theory of art appreciation that maintains appreciation depends on the viewer's ability to project his personality into the viewed object.
Not only do I see gravity and modesty and pride and courtesy and stateliness, but I feel or act them in the mind's muscles. This is, I suppose, a simple case of empathy, if we may coin that term as a rendering of Einfühlung; there is nothing curious or idiosyncratic about it; but it is a fact that must be mentioned. [Edward Bradford Titchener, "Lectures on the Experimental Psychology of the Thought Processes," 1909]
... there is no doubt that the facts are new and that they justify their name: the art work is a thing of "empathy" (Titchener, Ward), of "fellow feeling" (Mitchell), of "inner sympathy" (Groos), of "sympathetic projection" (Urban), of "semblance of personality" (Baldwin), all terms suggested by different writers as renderings of the German Einfühlung. ["The American Yearbook," 1911]
1590s, earlier nepenthes (1570s), "a drug or magic potion of Egypt mentioned in the 'Odyssey' as capable of banishing grief or trouble from the mind," from Greek nēpenthēs, from nē- "no, not" (from PIE root *ne- "not") + penthos "pain, grief," from PIE root *kwent(h)- "to suffer." The -s is a proper part of the word, but likely was mistaken in English as a plural affix and dropped. In medical use, "a drug having sedative properties" (1680s).
1857, "disease of the bones," from Greek osteon "bone" (from PIE root *ost- "bone") + -pathy "disorder, disease," from Greek -patheia, combining form of pathos "suffering, disease, feeling" (from PIE root *kwent(h)- "to suffer"). As a system of treating ailments by the manipulation of bones, it dates from 1889.
1590s, "affecting the emotions or affections, moving, stirring" (now obsolete in this broad sense), from French pathétique "moving, stirring, affecting" (16c.), from Late Latin patheticus, from Greek pathetikos "subject to feeling, sensitive, capable of emotion," from pathetos "liable to suffer," verbal adjective of pathein "to suffer" (from PIE root *kwent(h)- "to suffer").
The specific meaning "arousing pity, sorrow, or grief" or other tender feelings is from 1737. The colloquial sense of "so miserable as to be ridiculous" is attested by 1937. Related: Pathetical (1570s); pathetically. The pathetic fallacy (1856, first used by Ruskin) is the attribution of human qualities to inanimate objects.
