Principles of Legislation (1830), Ch. X : Analysis of Political Good and Evil; How they are spread in society
Context: It is with government, as with medicine. They have both but a choice of evils. Every law is an evil, for every law is an infraction of liberty: And I repeat that government has but a choice of evils: In making this choice, what ought to be the object of the legislator? He ought to assure himself of two things; 1st, that in every case, the incidents which he tries to prevent are really evils; and 2ndly, that if evils, they are greater than those which he employs to prevent them.
There are then two things to be regarded; the evil of the offence and the evil of the law; the evil of the malady and the evil of the remedy.
An evil comes rarely alone. A lot of evil cannot well fall upon an individual without spreading itself about him, as about a common centre. In the course of its progress we see it take different shapes: we see evil of one kind issue from evil of another kind; evil proceed from good and good from evil. All these changes, it is important to know and to distinguish; in this, in fact, consists the essence of legislation.
