The ethical schools of his day were already two; the one advocating dependent, the other independent morality; the one grounding obligation on self-love, the other on natural right. Shaftesbury, though a disciple of Locke, belonged to the latter school. His works mark the moment when this ethical school was passing from the objective inquiry into the immutability of right, as seen in Clarke, to the subjective inquiry into the reflex sense which constitutes our obligation to do what is right, as seen in Butler. The depreciation accordingly of the motives of reward, as distinct from the supreme motive of loving duty for duty’s sake, was to be expected in his system. The motives of reward and punishment which form the sanctions of religious obligation, would seem to him to be analogous to the employment of expedience as the foundation of moral. His statements however appear to be an exaggeration even in an ethical view, as well as calculated to insinuate erroneous ideas in a theological. It is possible that his motive was not polemical; but the unchristian character of his tone renders the hypothesis improbable, and explains the reason why his essays called the “Characteristics” have been ranked among deist writings. We have seen, in Toland and Shaftesbury respectively, a discussion on the metaphysical and ethical basis of religion, together with a few traces of the rise of criticism in reference to the canon. In their successors the inquiry becomes less psychological and more critical, and therefore less elevated by the abstract nature of the speculative above the struggle of theological polemic. Two branches of criticism were at this time commencing, which were destined to suggest difficulties alike to the deist and to the Christian; the one the discovery of variety of readings in the sacred text, the other the doubts thrown upon the genuineness and authenticity of the books. It was the large collection of various readings on the New Testament, first begun by Mills,(409) which gave the impulse to the former, which has been called the lower criticism, and which so distressed the mind of Bengel, that he spent his life in allaying the alarm of those who like himself felt alarmed at its effect on the question of verbal inspiration. And it was the disproof of the genuineness of the Epistles of Phalaris by the learned Bentley,(410) which first threw solid doubts on the value attaching to traditional titles of books, and showed the irrefragable character belonging to an appeal to internal evidence; a department which has been called the higher criticism. This latter branch, so abundantly developed in German speculation, is only hinted at by the English deists of the eighteenth age, as by Hobbes and Spinoza earlier; but we shall soon see the use which Collins and others made of the former inquiry.
