The son of a country curate, Paley began his career as tutor in an academy in Greenwich. He had entered Christ’s College, Cambridge, as “sizar.” Being senior wrangler of his year, he was afterwards elected a Fellow of his college. His lectures on moral philosophy at the University contained the germs of his most useful writing. After the usual previous stages, finally he received the preferment of the Archdeaconry of Carlisle. The failure of the most eminent of the modern apologists of dogmatic Christianity to attain the highest rewards of ecclesiastical ambition, and the refusal of George III. to promote “pigeon” Paley when it was proposed to that reactionary prince to make so skilful a controversialist a bishop--a refusal founded on the famous apology for monarchy in the _Moral and Political Philosophy_--is well known. The most important, by far, of his writings, is the _Elements of Moral and Political Philosophy_ (1785). He founds moral obligation upon principles of utility. In politics he asserts the grounds of the duties of rulers and ruled to be based upon the same far-reaching consideration, and upon this principle he maintains that as soon as any Government has proved itself corrupt or negligent of the public good, whatever may have been the alleged legitimacy of its original authority, the right of the governed to put an end to it is established. “The final view of all national politics,” he affirms, “is [ought to be] to produce the greatest quantity of happiness.” The comparative boldness, indeed, of certain of his disquisitions on Government alarmed not a little the political and ecclesiastical dignitaries of the time. His adhesion to the programme of Clarkson and the anti-slavery “fanatics” (as that numerically insignificant band of reformers was styled) did not tend, it may be presumed, to counteract the damaging effects of his political philosophy. In his _Natural Theology_ (1802), his best theological production, he labours to establish the fact of benevolent design from observation of the various phenomena of nature and life. Whatever estimate may be formed of the success of this undertaking, there can be no question of the ability and eloquence of the accomplished pleader; and the book proves him, at least, to have acquired a surprising amount of physiological and anatomical knowledge. It is justly described by Sir J. Mackintosh as “the wonderful work of a man who, after sixty, had studied anatomy in order to write it.” Of the _Evidences_ (1790-94)--the most popularly known of his writings--the considerable literary merit is in somewhat striking contrast, in regard to clearness and simplicity of style, with the ordinary productions of the evidential school.
