But what has been the Utility of those Schools? what Science is there at this day acquired by their Readings and Disputings? That wee have of Geometry, which is the Mother of all Naturall Science, wee are not indebted for it to the Schools. Plato that was the best Philosopher of the Greeks, forbad entrance into his Schoole, to all that were not already in some measure Geometricians. There were many that studied that Science to the great advantage of mankind: but there is no mention of their Schools; nor was there any Sect of Geometricians; nor did they then passe under the name of Philosophers. The naturall Philosophy of those Schools, was rather a Dream than Science, and set forth in senselesse and insignificant Language; which cannot be avoided by those that will teach Philosophy, without having first attained great knowledge in Geometry: For Nature worketh by Motion; the Wayes, and Degrees whereof cannot be known, without the knowledge of the Proportions and Properties of Lines, and Figures. Their Morall Philosophy is but a description of their own Passions. For the rule of Manners, without Civill Government, is the Law of Nature; and in it, the Law Civill; that determineth what is Honest, and Dishonest; what is Just, and Unjust; and generally what is Good, and Evill: whereas they make the Rules of Good, and Bad, by their own Liking, and Disliking: By which means, in so great diversity of taste, there is nothing generally agreed on; but every one doth (as far as he dares) whatsoever seemeth good in his own eyes, to the subversion of Common-wealth. Their Logique which should bee the Method of Reasoning, is nothing else but Captions of Words, and Inventions how to puzzle such as should goe about to pose them. To conclude there is nothing so absurd, that the old Philosophers (as Cicero saith, who was one of them) have not some of them maintained. And I beleeve that scarce any thing can be more absurdly said in naturall Philosophy, than that which now is called Aristotles Metaphysiques, nor more repugnant to Government, than much of that hee hath said in his Politiques; nor more ignorantly, than a great part of his Ethiques.
