His political and economical pamphlets are almost unmatched as clear presentations of the views of their writer. For driving the nail home no one but Swift excels him, and Swift perhaps only in _The Drapier's Letters_. There is often a great deal to be said against the view presented in those pamphlets, but Defoe sees nothing of it. He was perfectly fair but perfectly one-sided, being generally happily ignorant of everything which told against his own view.
The same characteristics are curiously illustrated in his moral works. The morality of these is almost amusing in its downright positive character. With all the Puritan eagerness to push a clear, uncompromising, Scripture-based distinction of right and wrong into the affairs of every-day life, he has a thoroughly English horror of casuistry, and his clumsy canons consequently make wild work with the infinite intricacies of human nature. He is, in fact, an instance of the tendency, which has so often been remarked by other nations in the English, to drag in moral distinctions at every turn, and to confound everything which is novel to the experience, unpleasant to the taste, and incomprehensible to the understanding, under the general epithets of wrong, wicked and shocking. His works of this class therefore are now the least valuable, though not the least curious, of his books.
The earliest regular life and estimate of Defoe is that of Dr Towers in the _Biographia Britannica_. George Chalmers's _Life_, however (1786), added very considerable information. In 1830 Walter Wilson wrote the standard _Life_ (3 vols.); it is coloured by political prejudice, but is a model of painstaking care, and by its abundant citations from works both of Defoe and of others, which are practically inaccessible to the general reader, is invaluable. In 1859 appeared a life of Defoe by William Chadwick, an extraordinary rhapsody in a style which is half Cobbett and half Carlyle, but amusing, and by no means devoid of acuteness. In 1864 the discovery of the six letters stirred up William Lee to a new investigation, and the results of this were published (London, 1869) in three large volumes. The first of these (well illustrated) contains a new life and particulars of the author's discoveries. The second and third contain fugitive writings assigned by Lee to Defoe for the first time. For most of these, however, we have no authority but Lee's own impressions of style, &c.; and consequently, though the best qualified judges will in most cases agree that Defoe may very likely have written them, it cannot positively be stated that he did. There is also a _Life_ by Thomas Wright (1894). The _Earlier Life and Chief Earlier Works_ of Defoe (1890) was included by Henry Morley in the "Carisbrooke Library." Charles Lamb's criticisms were made in three short pieces, two of which were written for Wilson's book, and the third for _The Reflector_. The volume on _Defoe_ (1879) in the "English Men of Letters" series is by W. Minto.
