As society cannot subsist unless the laws of justice are tolerably observed, as no social intercourse can take place among men who do not generally abstain from injuring one another

Context

“Upon a superficial view, this cause seems sufficient to produce the effects which are ascribed to it; and the system of human nature seems to be more simple and agreeable when all its different operations are in this manner deduced from a single principle. As society cannot subsist unless the laws of justice are tolerably observed, as no social intercourse can take place among men who do not generally abstain from injuring one another; the consideration of this necessity, it has been thought, was the ground upon which we approved of the enforcement of the laws of justice by the punishment of those who violated them. Man, it has been said, has a natural love for society, and desires that the union of mankind should be preserved for its own sake, and though he himself was to derive no benefit from it.” source
