History

Etymology

A modern translation of Latin, virtus dormitiva, coined by Molière in The Imaginary Invalid (1673). In the play, he lampoons a group of physicians providing an explanation in macaronic Latin of the sleep-inducing properties of opium as stemming from its "virtus dormitiva". The currency of this phrase as a critique of scientific claims is due to Gregory Bateson (1976, Steps to an Ecology of Mind p. 5), as is the translation of virtus as 'principle'.
