Laws are the terms under which independent and isolated men come together in society. Wearied by living in an unending state of war and by a freedom rendered useless by the uncertainty of retaining it, they sacrifice a part of that freedom in order to enjoy what remains in security and calm. The sum of these portions of freedom sacrificed to the good of all makes up the sovereignty of the nation, and the sovereign is the legitimate repository and administrator of these freedoms. But it was insufficient to create this repository; it was also necessary to protect it from the private usurpations of each individual, who is always seeking to extract from the repository not only his own due but also the portions which are owing to others. What were wanted were sufficiently tangible motives to prevent the despotic spirit of every man from resubmerging society's laws into the ancient chaos. These tangible motives are the punishments enacted against law-breakers. I say tangible motives because experience shows that the common run of men do not accept stable principles of conduct. Nor will they depart from the universal principle of anarchy which we see in the physical as well as in the moral realm, unless they are given motives which impress themselves directly on the senses and which, by dint of repetition, are constantly present in the mind as a counter-balance to the strong impressions of those self-interested passions which are ranged against the universal good.
