poetic practice of attributing human emotion or responses to nature, inanimate objects, or animals. The practice is a form of personification that is as old as poetry, in which it has always been common to find smiling or dancing flowers, angry or cruel winds, brooding mountains, moping owls, or happy larks. The term was coined by John Ruskin in Modern Painters (1843–60). In some classical poetic forms such as the pastoral (pastoral literature) elegy, the pathetic fallacy is actually a required convention. In Milton's (Milton, John) “On The Morning of Christ's Nativity,” all aspects of nature react affectively to the event of Christ's birth.

Ruskin considered the excessive use of the fallacy the mark of an inferior poet. Later poets, however—especially the Imagists of the early 20th century, as well as T.S. Eliot and Ezra Pound—used the pathetic fallacy freely and effectively.
