Utilitarianism is an ethical theory holding that the proper course of action is the one that maximizes the overall "happiness". It is thus a form of consequentialism, meaning that the moral worth of an action is determined only by its resulting outcome, and that one can only weigh the morality of an action after knowing all its consequences. Two influential contributors to this theory are Jeremy Bentham and John Stuart Mill. Utilitarianism was described by Mill as "the greatest happiness principle" and by Bentham as the "pleasure principle".

Utilitarianism can be characterised as a quantitative and reductionist approach to ethics. It is a type of naturalism. It can be contrasted with deontological ethics (which do not regard the consequences of an act as a determinant of its moral worth), pragmatic ethics, virtue ethics (which focuses on character) and deontological varieties of libertarianism, as well as with ethical egoism and other varieties of consequentialism.

Although modern utilitarianism is usually thought to start with Jeremy Bentham there were earlier writers who presented theories that were strikingly similar. In An Enquiry Concerning the Principles of Morals David Hume writes:

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
