The first design of the Essay on Man arranged it into four books, each consisting of a distinct group of Epistles. The First Book, in four Epistles, was to treat of man in the abstract, and of his relation to the Universe. That is the whole work as we have it now. The Second Book was to treat of Man Intellectual; the Third Book, of Man Social, including ties to Church and State; the Fourth Book, of Man Moral, was to illustrate abstract truth by sketches of character. This part of the design is represented by the Moral Essays, of which four were written, to which was added, as a fifth, the Epistle to Addison which had been written much earlier, in 1715, and first published in 1720. The four Moral essays are two pairs. One pair is upon the Characters of Men and on the Characters of Women, which would have formed the opening of the subject of the Fourth Book of the Essay: the other pair shows character expressed through a right or a wrong use of Riches: in fact, Money and Morals. The four Epistles were published separately. The fourth (to the Earl of Burlington) was first published in 1731, its title then being "Of Taste;" the third (to Lord Bathurst) followed in 1732, the year of the publication of the first two Epistles on the "Essay on Man." In 1733, the year of publication of the Third Epistle of the "Essay on Man," Pope published his Moral Essay of the "Characters of Men." In 1734 followed the Fourth Epistle of the "Essay on Man;" and in 1735 the "Characters of Women," addressed to Martha Blount, the woman whom Pope loved, though he was withheld by a frail body from marriage. Thus the two works were, in fact, produced together, parts of one design.
