§ IV. As to the _Method_ of Thinking, if it be proper for me to say any thing of that, after those better Pens which have treated of it already, it falls in with the Subject I’me now come to, which is, that _Natural Logic_ I wou’d propose. I call it natural because I shall not send you further than your Own Minds to learn it, you may if you please take in the assistance of some well chosen Book, but a good Natural Reason after all, is the best Director, without this you will scarce Argue well, tho you had the Choicest Books and Tutors to Instruct you, but with it you may, tho’ you happen to be destitute of the other. For as a very Judicious Writer on this Subject (to whose Ingenious Remarks and Rules I am much obliged) well observes, “These Operations [of the Mind] proceed meerly from Nature, and that sometimes more perfectly from those who are altogether ignorant of Logic, than from others who have learn’d it.” That which we propose in all our Meditations and Reasonings is, either to deduce some Truth we are in search of, from such Principles as we’re already acquainted with; or else, to dispose our Thoughts and Reasonings in such a manner, as to be able to Convince others of those Truths which we our selves are Convinc’d of. Other Designs indeed Men may have, such as the Maintenance of their Own Opinions, Actions and Parties without regard to the Truth and Justice of ’em, or the Seduction of their unwary Neighbours, but these are Mean and Base ones, beneath a Man, much more a Christian, who is or Ought to be endow’d with greater Integrity and Ingenuity.
