Purpose or function of law
From Textop Wiki
Civil laws aim at peace and self-preservation—it is easy but also dangerous to break them.
But as men, for the attaining of peace and conservation of themselves thereby, have made an artificial man, which we call a Commonwealth; so also have they made artificial chains, called civil laws, which they themselves, by mutual covenants, have fastened at one end to the lips of that man, or assembly, to whom they have given the sovereign power, and at the other to their own ears. These bonds, in their own nature but weak, may nevertheless be made to hold, by the danger, though not by the difficulty of breaking them.
Hobbes, Lev XXI 5
