In looking over the catalogue of human actions (says a partizan of this principle) in order to determine which of them are to be marked with the seal of disapprobation, you need but to take counsel of your own feelings: whatever you find in yourself a propensity to condemn, is wrong for that very reason. For the same reason it is also meet for punishment: in what proportion it is adverse to utility, or whether it be adverse to utility at all, is a matter that makes no difference. In that same proportion also is it meet for punishment: if you hate much, punish much: if you hate little, punish little: punish as you hate. If you hate not at all, punish not at all: the fine feelings of the soul are not to be overborne and tyrannized by the harsh and rugged dictates of political utility.
