If the "Gentlemen of Abilities" of the day found some of Morris's definitions obscure, modern readers will find them more precise than those of most of his predecessors. All who had gone before--Cowley, Barrow, Dryden, Locke, Addison, and Congreve (he does not mention Hobbes)--Morris felt had bungled the job. And although he apologizes for attempting what the great writers of the past had failed to do, he has no hesitation in setting forth exactly what he believes to be the proper distinctions in the meanings of such terms as wit, humour, judgment, invention, raillery, and ridicule. The mathematician and statistician in Morris made him strive for precise accuracy. It was all very clear to him, and by the use of numerous anecdotes and examples he hoped to make the distinctions obvious to the general reader. The _Essay_ shows what a man of some evident taste and perspicacity, with an analytical mind, can do in defining the subtle semantic distinctions in literary terms. Trying to fix immutably what is certain always to be shifting, Morris is noteworthy not only because of the nature of his attempt, but because he is relatively so successful. As Professor Edward Hooker has pointed out in an Introduction to an earlier _ARS_ issue (Series I, No. 2), his is "probably the best and clearest treatment of the subject in the first half of the eighteenth century." It may be regretted that political and economic concerns occupied so much of his later life, leaving him no time for further literary essays. In the present facsimile edition, for reasons of space, only the Introduction and the main body of the _Essay_ are reproduced. Although Morris once remarked to David Hume that he wrote all his books "for the sake of the Dedications" (_Letters of David Hume_ ed. Greig, I, 380), modern readers need not regret too much the omission of the fulsome 32 page dedication to Walpole (The Earl of Orford). Morris insists at the beginning that the book was inspired by a fervent desire of "attempting a Composition, independent of Politics, which might furnish an occasional Amusement" to his patron. The praise which follows, in which Walpole is said to lead "the _Empire_ of _Letters_," is so excessive as to produce only smiles in twentieth century readers. Walpole is praised for not curbing the press while necessarily curbing the theatre, his aid to commerce and industry, indeed almost every act of his administration, is lauded to the skies. The Church of England, in which "the _Exercise_ of _Reason_ in the solemn Worship of God, is the sacred _Right_, and indispensible _Duty_, of Man," receives its share of eulogy. In every connection the Tories are violently attacked. The Dedication ends in a peroration of praise for Walpole's public achievements which "shall adorn the History of _Britain_," and for his "_Private Virtues_ and all the _softer Features_" of his mind. His home of retirement is referred to in the lines of Milton:
