Jeremy Bentham, The Greatest Happiness of the Greatest Number: Section II. First Principles Enumerated — The Proper End of Government
The right and proper end of government in every political community, is the greatest happiness of all the individuals of which it is composed, say, in other words, the greatest happiness of the greatest number.
In speaking of the correspondent first principle, call it the greatest-happiness principle.
In speaking of this end of government, call it the right and proper end of government.
The actual end of government is, in every political community, the greatest happiness of those, whether one or many, by whom the powers of government are exercised.
