The way also wherein the Names of mixed Modes are ordinarily learned, does not a little contribute to the doubtfulness of their signification. For if we will observe how Children learn Languages, we shall find, that to make them understand what the Names, of simple Ideas, or Substances, stand for, People ordinarily shew them the thing, whereof they would have them have the Idea; and then repeat to them the Name that stands for it, as White, Sweet, Milk, Sugar, Cat, Dog. But as for mixed Modes, especially the most material of them moral Words, the Sounds are usually learn'd first, and then to know what complex Ideas they stand for, they are either beholden to the explication of others, or (which happens for the most part) are lest to their own Observation and Industry; which being little laid out in the search of the true and precise meaning of Names, these moral Words are, in most Mens mouths, little more than bare Sounds; or when they have any, 'tis for the most part but a very obscure and confused signification. And even those themselves, who have with more attention setled their Notions, do yet hardly avoid the inconvenience, to have them stand for complex Ideas, different from those which other, even intelligent and studious Men, make them the signs of. Where shall one find any, either controversial Debate, or familiar Discourse, concerning Honour, Faith, Grace, Religion, Church, &c. wherein it is not easie to observe the different Notions Men have of them; which is nothing but this, that they are not agreed in the signification of those Words, have not the same complex Ideas they make them stand for: And so all the contests that follow thereupon, are only about the meaning of a Sound. And hence we see, that in the interpretation of Laws, whether Divine, or Humane, there is no end; Comments beget Comments, and Explications make new matter for Explications: And of limitting, distinguishing, varying the signification of these moral Words, there is no end. These Ideas of Mens making, are, by Men still having the same Power, multiplied in infinitum. Many a Man, who was pretty well satisfied of the meaning of a Text of Scripture, or Clause in the Code, at first reading, has, by consulting Commentators, quite lost the sense of it, and, by those Elucidations, given rise or increase to his Doubts, and drawn obscurity upon the place. I say not this, that I think Commentaries needless; but to shew how uncertain the Names of mixed Modes naturally are, even in the mouths of those, who had both the Intention and the Faculty of Speaking, as clearly as Language, was capable to express their Thoughts.
