"The Greatest Happiness of the Greatest Number"
In An Introduction to the Principles of Morals and Legislation Bentham proposed that "nature has placed mankind under the governance of two sovereign masters, pain and pleasure… it is for them alone to point out what we ought to do," and that the moral value of all laws, institutions, and individual acts should be judged by the sole standard of whether they achieve "the greatest happiness of the greatest number" — this thoroughgoing utilitarian logic of calculation sought to provide an objective, quantifiable rational basis for ethical and legal judgment.
