37. The manner of sorting particular beings the work of fallible men, though nature makes things alike.
I do not
deny but nature, in the constant production of particular beings, makes them not always new and various, but very
much alike and of kin one to another: but I think it nevertheless true, that the boundaries of the species, whereby
men sort them, are made by men; since the essences of the species, distinguished by different names, are, as has
been proved, of man's making, and seldom adequate to the internal nature of the things they are taken from. So
that we may truly say, such a manner of sorting of things is the workmanship of men.
