Utilitarianism
Utilitarianism is a union of hedonism and Christianity. The first teaches man to love pleasure; the second, to love his neighbor. The union consists in teaching man to love his neighbor’s pleasure. To be exact, the Utilitarians teach that an action is moral if its result is to maximize pleasure among men in general. This theory holds that man’s duty is to serve—according to a purely quantitative standard of value. He is to serve not the well-being of the nation or of the economic class, but “the greatest happiness of the greatest number,” regardless of who comprise it in any given issue. As to one’s own happiness, says [John Stuart] Mill, the individual must be “disinterested” and “strictly impartial”; he must remember that he is only one unit out of the dozens, or millions, of men affected by his actions. “All honor to those who can abnegate for themselves the personal enjoyment of life,” says Mill, “when by such renunciation they contribute worthily to increase the amount of happiness in the world.”
“The greatest good for the greatest number” is one of the most vicious slogans ever foisted on humanity.
This slogan has no concrete, specific meaning. There is no way to interpret it benevolently, but a great many ways in which it can be used to justify the most vicious actions.
What is the definition of “the good” in this slogan? None, except: whatever is good for the greatest number. Who, in any particular issue, decides what is good for the greatest number? Why, the greatest number.
If you consider this moral, you would have to approve of the following examples, which are exact applications of this slogan in practice: fifty-one percent of humanity enslaving the other forty-nine; nine hungry cannibals eating the tenth one; a lynching mob murdering a man whom they consider dangerous to the community.
There were seventy million Germans in Germany and six hundred thousand Jews. The greatest number (the Germans) supported the Nazi government which told them that their greatest good would be served by exterminating the smaller number (the Jews) and grabbing their property. This was the horror achieved in practice by a vicious slogan accepted in theory.
But, you might say, the majority in all these examples did not achieve any real good for itself either? No. It didn’t. Because “the good” is not determined by counting numbers and is not achieved by the sacrifice of anyone to anyone.
