for without law man is the worst of animals, and law depends, for its existence, on the State.

Context

“The implication is that a hand is to be defined by its purpose—that of grasping—which it can only perform when joined to a living body. In like manner, an individual cannot fulfil his purpose unless he is part of a State. He who founded the State, Aristotle says, was the greatest of benefactors; for without law man is the worst of animals, and law depends, for its existence, on the State. The State is not a mere society for exchange and the prevention of crime: “The end of the State is the good life. . . . And the State is the union of families and villages in a perfect and self-sufficing life, by which we mean a happy and honourable life”” source
