1903, from German Einfühlung (from ein "in" + Fühlung "feeling"), coined 1858 by German philosopher Rudolf Lotze (1817-1881) as a translation of Greek empatheia "passion, state of emotion," from en "in" (see en- (2)) + pathos "feeling" (see pathos). 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.
