Means and Instruments which Religion it self makes use of in the Defence and Explication of its Boctrines; as we shall see in the Close of this Discourse.
These are the Reflections that may be made upon the Use of Philosophy in General. Let us proceed to take a View of its Parts as they stand distinctly from each other.

This pure and uncorrupted Light was soon vitiated and obscur'd; and Human Reason which had submitted to its Guidance, was led astray by its Abuse. Thus Logick, which was invented to fix and rectifie the Understanding, help'd to seduce and pervert it; and the first
Pro Precepts that were given to lead Men to Knowledge, were but so many Snares to betray them into Error. For as nothing is more Secret than Thought, so Logick was at first nothing else but an Art of variously disguising our Thoughts; as appears from the History of its Rise and For. tune in the World.
II. The first Philosophers, who praais'd Reason more than Argument, were so entirely bent on the Study of Nature, as to have little regard to Logical Speculations: They reason'd upon their own Experience, and yet were Strangers to the Art and Method of Reasoning. In Pythagoras's Platonem School, there was no Logick but Authority ; no à PhytbaAppeal from what he pleas'd to dictate. In-goricis indeed Apuleius pretends, that Plato borrow'd telle&uahis first Draught of Logick from the Pythago - Sophie

This was his Way; he explain'd himself only in Dialogue, and Introduc'd two or more Persons, who by their Course of Questions and Answers, reason'd methodically upon all Subjects: And 'twas from this method of Dialogue, that he gave his new invented Art the Name of Dialeštica ; and this put a Period to the more ancient

From the same Euclid, Demosthenes learnt his Art of Dilemma, and those presling ways of Address, which rendred him fo forcible in his Character of Eloquence. Plato's Logick, which is the same with that of Socrates, consists more in Examples than in Precepts: It has nothing peculiar as to the difputative Part, of which Socrates had but a very mean Opinion: Tho’ both the one and the
