lessons rescued the academy of Lausanne from Calvinistic prejudice; and he had the rare merit of diffusing a more liberal spirit among the clergy and people of the Pays de Vaud. His system of logic, which in the last editions has swelled to six tedious and prolix volumes, may be praised as a clear and methodical abridgment of the art of reasoning, from our simple ideas to the most complex operations of the human understanding. This system I studied, and meditated, and abstracted, till I have obtained the free command of an universal instrument, which I soon presumed to exercise on my catholic opinions. Pavilliard was not unmindful that his first task, his most important duty, was to reclaim me from the errors of popery. The intermixture of sects has rendered the Swiss clergy acute and learned on the topics of controversy; and I have some of his letters in which he celebrates the dexterity of his attack, and my gradual concessions after a firm and well-managed defence. I was willing, and I am now willing, to allow him a handsome share of the honour of my conversion: yet I must observe, that it was principally effected by my private reflections; and I still remember my solitary transport at the discovery of a philosophical argument against the doctrine of transubstantiation: that the text of scripture, which seems to inculcate the real presence, is attested only by a single sense--our sight; while the real presence itself is disproved by three of our senses--the sight, the touch, and the taste. The various articles of the Romish creed disappeared like a dream; and after a full conviction, on Christmas-day, 1754, I received the sacrament in the church of Lausanne. It was here that I suspended my religious inquiries, acquiescing with implicit belief in the tenets and mysteries, which are adopted by the general consent of catholics and protestants.
