Before proceeding, we may make a few admissions which will narrow the field of dispute; and we may as well leave behind a few prejudices, which intelligent opponents of Utilitarianism have by this time 'agreed to discard'. We admit that Utility is coextensive with right, and that no action can be right which does not tend to the happiness of mankind; we acknowledge that a large class of actions are made right or wrong by their consequences only; we say further that mankind are not too mindful, but that they are far too regardless of consequences, and that they need to have the doctrine of utility habitually inculcated on them. We recognize the value of a principle which can supply a connecting link between Ethics and Politics, and under which all human actions are or may be included. The desire to promote happiness is no mean preference of expediency to right, but one of the highest and noblest motives by which human nature can be animated. Neither in referring actions to the test of utility have we to make a laborious calculation, any more than in trying them by other standards of morals. For long ago they have been classified sufficiently for all practical purposes by the thinker, by the legislator, by the opinion of the world. Whatever may be the hypothesis on which they are explained, or which in doubtful cases may be applied to the regulation of them, we are very rarely, if ever, called upon at the moment of performing them to determine their effect upon the happiness of mankind.
