41. Artificial things of distinct species.
I must be excused here if I think artificial things are of distinct species as
well as natural: since I find they are as plainly and orderly ranked into sorts, by different abstract ideas, with
general names annexed to them, as distinct one from another as those of natural substances. For why should we
not think a watch and pistol as distinct species one from another, as a horse and a dog; they being expressed in our
minds by distinct ideas, and to others by distinct appellations?
