Neither is it necessary to reduce the most usual Sophisms to general Heads, since that’s already very well perform’d in a Book to which I’de rather refer you, than be at the trouble of Transcribing, having nothing to add but this, that if I be not mistaken, all the false Arguings enumerated there, and what others you may happen to meet with may be discover’d and avoided by the Rules already given, and do indeed proceed, so far as they relate to the Understanding, from the Non-observation of some of ’em. But it is to little purpose to guard our selves against the Sophisms of the Head, if we lie open to those of the Heart. One irregular Passion will put a greater Obstacle between us and Truth, than the brightest Understanding and clearest Reasonings can easily remove. This every one of us is apt to discern in others, but we’re blind to it in our selves. We can readily say that it is Pride or Obstinacy, Interest or Passion or in a word Self-love that keeps our Neighbour from Conviction, but all this while imagine our own Hearts are very clear of ’em, tho’ more Impartial Judges are of another Mind. I wish there were no Reason to think that there are some who attempt to maintain an Opinion which they know to be false, or at least which they have cause to suspect, and therefore industriously avoid what wou’d manifest their Error. ’Tis hop’d however that the greatest part of the Disputers of the World are not of this number, and that the reason why they offer their Neighbours Sophistical Arguments, is because they are not aware of it themselves; That what makes them so Positive is their firm persuasion that they are acted only by a Zeal for GOD, an honest Constancy and Stanch Integrity, tho at the very same time quite different Motives move them under these Appearances. And indeed he must be an extraordinary good Man, a Wonder scarce produc’d in an Age, who has no Irregular Passion stirring; Who receives no Manner of Tincture from Pride and Vitious Self-Love, to which all are so prone, and which hide themselves under so many disguises; Who is got above the World its Terrors and Allurements, has laid up his Treasure in Heaven, and is fully Contented with his Present Circumstances, let them be what they will, having made them the boundaries of his Desires; who knows how to live on a Little very happily and therefore receives no Bias from his own Conveniency, nor is weigh’d down by the dead Weight of his Appetites and Interests; which ought to be the Temper of every Person who wou’d find out Truth, and who desires to make a Right Judgment in all things.
