Pope's Essay on Man and Moral Epistles were designed to be the parts of a system of ethics which he wanted to express in poetry. Moral Epistles have been known under various other names including Ethic Epistles and Moral Essays.
On its publication, An Essay on Man met with great admiration throughout Europe. Voltaire called it "the most beautiful, the most useful, the most sublime didactic poem ever written in any language".[citation needed] In 1756 Rousseau wrote to Voltaire admiring the poem and saying that it "softens my ills and brings me patience". Kant was fond of the poem and would recite long passages of the poem to his students.[2]
Later however, Voltaire renounced his admiration for Pope and Leibniz's optimism and even wrote a novel, Candide, as a satire on Pope and Leibniz's philosophy of ethics. Rousseau also critiqued the work. He questioned "Pope's uncritical assumption that there must be an unbroken chain of being all the way from inanimate matter up to God."[3]
The essay, written in heroic couplets, comprises four epistles. Pope began work on it in 1729, and had finished the first three by 1731. They appeared in early 1733, with the fourth epistle published the following year. The poem was originally published anonymously; Pope did not admit authorship until 1735.
