A man, to be greatly good, must imagine intensely and comprehensively; he must put himself in the place of another and of many others; the pains and pleasure of his species must become his own. The great instrument of moral good is the imagination; and poetry administers to the effect by acting upon the cause.

Percy Bysshe Shelley (1792–1822) English poet

“A Defence of Poetry” (1821-03, pub. 1840)
