It is the Nature almost of every Corporal Thing, being often moved in one and the same Manner, to receive continually a greater and greater Easiness and Aptitude to the same Motion, insomuch as in Time the same becometh so habitual, that, to beget it, there needs no more than to begin it. The Passions of Man, as they are the Beginning of voluntary Motions; so are they the Beginning of Speech, which is the Motion of the Tongue. And Men desiring to shew others the Knowledge, Opinions, Conceptions and Passions which are in themselves, and to that End having invented Language, have by that Means transferred all that Discursion of their Mind mentioned in the former Chapter, by the Motion of their Tongues, into Discourse of Words: And Ratio now is but Oratio, for the most part, wherein Custom hath so great a Power, that the Mind suggesteth only the first Word; the rest follow habitually, and are not followed by the Mind; as it is with Beggars, when they saw their Pater noster, putting together such Words, and in such manner, as in their Education they have learned from their Nurses, from their Companies, or from their Teachers, having no Images or Conceptions in their Mind, answering to the Words they speak: and as they have learned themselves, so they teach Posterity. Now if we consider the Power of those Deceptions of the Sense, mentioned Chap 2. Sect. 10 and also how unconstantly Names have been setled, and how subject they are to Æquivocation, and how diversified by Passion, (scarce two Men agreeing what is to be called Good, and what Evil; what Liberality, what Prodigality; what Valour, what Temerity) and how subject Men are to Paralogism or Fallacy in Reasoning, I may in a Manner conclude, that it is impossible to rectifie so many Errours of any one Man, as must needs proceed from those Causes, without beginning a-new from the very first Grounds of all our Knowledge and Sense; and instead of Books, reading over orderly ones own Conceptions: In which Meaning, I take Noste teipsum for a Precept worthy the Reputation it hath gotten.
