But as far as possible to elucidate the idea, I will endeavour to illustrate it by a still plainer example. Let us suppose the inquiry to be about some tree, whether it is cultivated or wild. If the former, we call it planted, if the latter, not planted. And such a term exactly hits the truth, for the tree must needs be after this manner or that. And yet the word does not indicate the peculiar nature of the plant. From the term “not-planted” we learn that it is of spontaneous growth; but whether what is thus signified is a plane, or a vine, or some other such plant, the name applied to it does not inform us.
