living things or animals, including of course the angler among them. The hunters of animals are distinguished into hunters of walking animals, and hunters of swimming animals. Of the swimming animals some are in air, others in water:[11] hence we get two classes, Bird-Hunters and Fish-Hunters; to the last of whom the angler belongs. The fish-hunters (or fishermen) again are bisected into two classes, according as they employ nets, or striking instruments of one kind or another, such as tridents, &c. Of the striking fishermen there are two sorts: those who do their work at night by torch-light, and those who work by day. All these day-fishermen, including among them the angler, use instruments with hooks at the end. But we must still make one bisection more. Some of them employ tridents, with which they strike from above downwards at the fishes, upon any part of the body which may present itself: others use hooks, rods, and lines, which they contrive to attach to the jaws of the fish, and thereby draw him from below upward.[12] This is the special characteristic of the angler. We have now a class comprehending the anglers alone, so that no farther sub-division is required. We have obtained not merely the name of the angler, but also the rational explanation of the function to which the name is attached.[13] [Footnote 10: Plato, Sophist. p. 218 E.] [Footnote 11: Plato, Sophist. p. 220 B.
