Philosophy Exam 2 Q1 - The Greatest Happiness Principle

Mill argues that morality needs a criterion of right and wrong and identifies that criterion with the Greatest Happiness Principle.

John Stuart Mill argues that morality needs an ultimate standard for determining whether actions are right or wrong. He identifies this standard with the Greatest Happiness Principle, also called the Principle of Utility.

First, explain what Mill means by saying that actions are right insofar as they tend to promote happiness and wrong insofar as they tend to produce the reverse of happiness.

According to this principle, actions are right insofar as they tend to promote happiness and wrong insofar as they tend to produce the reverse of happiness. Mill does not mean that every individual action must happen to produce a good result in every unusual case. Instead, he is concerned with the predictable tendency of an action or type of action. Kicking a ball through a room full of delicate glassware, for example, generally tends to cause damage and unhappiness, even if an unusual instance of doing so happened to reveal something valuable hidden behind a vase. Moral evaluation should therefore be based on the normal and foreseeable consequences of actions rather than on accidental results.

What does Mill mean by “happiness”?

Mill defines happiness as pleasure and the absence of pain, while unhappiness consists in pain and the lack of pleasure. Critics sometimes interpret this view as reducing human life to basic bodily enjoyment, but Mill rejects that interpretation. Human beings possess intellectual, emotional, imaginative, and moral capacities that allow them to experience pleasures of a higher quality than simple physical gratification. Someone who has experienced both kinds of pleasure will generally prefer activities that exercise these higher capacities, even when those activities involve difficulty or dissatisfaction. This is why Mill claims that it is better to be “Socrates dissatisfied than a fool satisfied.” A thoughtful, intellectually engaged life may not always be easier or more pleasant in a simple quantitative sense, but it is better because it involves higher forms of human enjoyment.

Why do consequences matter in his view, and why must each person’s happiness count equally?

Consequences matter because Mill believes that happiness is the only ultimate end that is desirable for its own sake. Other things, such as money, health, friendship, or virtue, may be valuable, but they are valuable because they contribute to happiness or become part of what a person understands a happy life to include. Since happiness and freedom from pain are the ultimate ends of human action, the moral value of an action depends on whether its expected consequences increase or decrease overall happiness. For example, if a doctor has five doses of a life-saving medicine and must choose between giving all five doses to one patient or distributing one dose to each of five patients, utilitarianism supports saving the five patients. That choice prevents more suffering and preserves more happiness than saving only one person. Each person’s happiness must count equally because no individual’s welfare is inherently more important than anyone else’s. As Bentham puts the point, “Everybody [is] to count for one, nobody for more than one.” A person cannot simply give special weight to their own preferences because they are their own. If a family is choosing dinner and Chinese food would make everyone else much happier than Thai food, a utilitarian should choose Chinese food even if Thai is their personal favorite. The same principle applies on a broader scale. A stranger’s suffering matters just as much as the suffering of someone nearby or someone we know personally. This is the force of the drowning-child example: if someone can save a child from drowning at the small cost of ruining expensive shoes, they ought to do so because the child’s life and suffering carry far greater moral weight than the loss of property.

Then explain why Mill does not think that people must calculate the consequences of every individual action from scratch at every moment.

A common objection to utilitarianism is that it seems impossible to calculate all the consequences of every action before acting. Mill does not believe that people must begin a completely new calculation at every moment. Human beings can rely on accumulated experience about the ordinary effects of actions. Across generations, people have learned that actions such as murder, theft, assault, deception, and broken promises usually cause suffering, undermine trust, and make social life worse. This knowledge gives rise to moral rules and secondary principles, such as “do not lie,” “do not steal,” “do not harm others,” and “keep promises.”

What role do moral rules and secondary principles play in utilitarian moral reasoning?

These secondary principles make utilitarianism practical. They act as rules of thumb that normally guide conduct without requiring someone to calculate every possible consequence from the beginning. Mill compares them to signposts that help a traveler reach a destination. The Greatest Happiness Principle is the ultimate destination, while ordinary moral rules are the reliable guides people use in daily life. Following these rules usually promotes happiness because they protect trust, safety, and cooperation. People are therefore generally right to rely on moral rules rather than constantly performing detailed calculations about utility.

Finally, explain the tension between the Greatest Happiness Principle and moral rules. If breaking a rule such as “do not steal” would produce the greatest overall happiness in a particular case, is the action right?

However, secondary rules are not the final standard of morality. They are justified because they usually promote overall happiness, and they can be overridden when following them would clearly lead to a much worse outcome. This creates a tension between the Greatest Happiness Principle and ordinary moral rules. Rules against theft, for example, are important because property rights and social trust usually contribute to security and well-being. Similarly, utilitarianism normally rejects the idea of a surgeon secretly taking organs from one healthy person to save five others or a sheriff framing an innocent person to stop a riot. Even if these actions might seem beneficial in a single isolated case, allowing institutions to violate rights in this way would destroy public trust in hospitals and courts. The long-term fear, insecurity, and suffering produced by such practices would outweigh the short-term benefit.

Still, Mill recognizes that extraordinary circumstances can justify setting aside an ordinary rule. If stealing food or medicine is necessary to prevent an innocent person from starving or dying, then the person may be morally justified in stealing it. Likewise, forcibly bringing the only qualified doctor to an emergency could be justified if doing so is necessary to save someone’s life. In these cases, blindly following the rule against theft or coercion would produce a catastrophic loss of happiness. Mill’s point is not that the action is merely a “pardonable injustice.” Rather, what would ordinarily count as unjust can cease to be unjust when the consequences are sufficiently different.

Therefore, if breaking a rule such as “do not steal” would truly produce the greatest overall happiness in a particular case, the action is right. In an extreme emergency, it may even be morally required. Nevertheless, this does not make moral rules unimportant. They remain essential because they reflect the accumulated human knowledge that certain forms of conduct generally promote happiness and reduce suffering. The Greatest Happiness Principle is the ultimate standard, while moral rules are the practical and usually reliable guides that help people achieve it.
