On the accession of George I. to the British throne in 1714, Sir Isaac Newton became an object of interest at court. His high situation under government, his splendid reputation, his spotless character, and, above all, his unaffected piety attracted the attention of the Princess of Wales, afterward queen-consort to George II. This lady, who possessed a highly cultivated mind, derived the greatest pleasure from conversing with Newton and corresponding with Leibnitz. In all her difficulties, she received from Sir Isaac that information and assistance which she had elsewhere sought in vain, and she was often heard to declare in public that she thought herself fortunate in living at a time which enabled her to enjoy the conversation of so great a genius. But while Newton was thus esteemed by the house of Hanover, Leibnitz, his great rival, endeavoured to weaken and undermine his influence. In his correspondence with the princess, he represented the Newtonian philosophy, not only as physically false, but as injurious to the interests of religion. He asserted that natural religion was rapidly declining in England, and he supported this position by referring to the works of Locke, and to the beautiful and pious sentiments contained in the 28th query at the end of the Optics. He represented the principles of these great men as precisely the same with those of the materialists, and thus endeavoured to degrade the character of English philosophers. These attacks of Leibnitz became subjects of conversation at court, and when they reached the ear of the king, his majesty expressed his expectation that Sir Isaac Newton would draw up a reply. He accordingly entered the lists on the mathematical part of the controversy, and left the philosophical part of it to Dr. Clarke, who was a full match for the German philosopher. The correspondence which thus took place was carefully perused by the princess, and from the estimation in which Sir Isaac continued to be held, we may infer that the views of the English philosopher were not very remote from her own.
