1866, reintroduced by English anthropologist Sir Edward Burnett Taylor (1832-1917), who defined it (1871) as the "theory of the universal animation of nature," from Latin anima "life, breath, soul" (see animus) + -ism.
Earlier sense was of "doctrine that animal life is produced by an immaterial soul" (1832), from German Animismus, coined c.1720 by physicist/chemist Georg Ernst Stahl (1660-1734) based on the concept of the anima mundi. Animist is attested from 1819, in Stahl's sense; animisic is first recorded 1871.
