Pathetic Fallacy is the poetic practice whereby natural phenomena which cannot feel as humans do are described as if they could.
The pathetic fallacy usually involves the application of some METAPHOR which falls short of full-scale PERSONIFICATION in its treatment of the natural world.
The term was coined by the influential Victorian art critic John Ruskin in the third volume of his Modern Painters (1856).
