Indeed, to a man that knows the signification of the word metal, and not of the word lead, it is a shorter way to explain the signification of the word lead, by saying it is a metal, which at once expresses several of its simple ideas, than to enumerate them one by one, telling him it is a body very heavy, fusible, and malleable.
Benetan ere, metal hitzaren esanahia ezagutzen duen baina berun hitzarena ezagutzen ez duen batek berun hitzak zer esan nahi duen uler dezan, bide laburragoa da metal bat dela esatea, horrek haren ideietako batzuk batera adierazten baititu, ideia horiek banan-bana esatea baino, gorputz oso astuna, fundigarria eta xaflakorra dela esanez.
