Utilitarianism: What It Is and Its Role in Ethics

Understanding utilitarianism: definition, explanation, and its role in ethics

What is Utilitarianism?

Utilitarianism is a philosophical theory that suggests the morally right course of action is the one that maximizes overall happiness or ‘utility’. This theory, which is a form of consequentialism, holds that the moral worth of an action is determined solely by its contribution to overall utility, that is, its contribution to happiness or pleasure as summed among all individuals. The term utilitarianism was first coined by the philosopher John Stuart Mill, who expanded on the ideas of Jeremy Bentham, the founder of the theory.

The Principles of Utilitarianism

Utilitarianism operates on two basic principles: the principle of utility and the principle of impartiality. The principle of utility states that actions or behaviors are right in so far as they promote happiness or pleasure, and wrong as they tend to produce unhappiness or pain. The principle of impartiality suggests that everyone’s happiness counts equally. In other words, the happiness of one individual is not considered more important than the happiness of another.

Types of Utilitarianism

There are two main types of utilitarianism: act utilitarianism and rule utilitarianism.

Act Utilitarianism

Act utilitarianism asserts that the morality of an action is to be judged solely by its consequences. This means that the most ethical choice is the one that will produce the greatest good for the greatest number. It requires us to weigh the consequences of our actions before deciding on a course of action.

Rule Utilitarianism

Rule utilitarianism, on the other hand, suggests that the moral correctness of an action depends on the correctness of the rules that allows it to achieve the greatest good. It emphasizes the value of following rules that have been designed to promote the greater good.

Utilitarianism in Ethics

Utilitarianism plays a significant role in ethics, particularly in making decisions that affect large groups of people. It provides a useful framework for lawmakers, business leaders, and individuals to make decisions that consider the overall happiness or well-being of a community or society. By focusing on the greatest good for the greatest number, utilitarianism encourages decisions that are fair and impartial.

Criticisms of Utilitarianism

Despite its widespread use, utilitarianism is not without its critics. Some argue that it is too demanding, requiring people to always act in the interest of the greatest number, even if it goes against their own personal interests. Others argue that it fails to respect individual rights and can justify harmful actions if they result in a greater overall good. Despite these criticisms, utilitarianism remains a powerful tool for ethical decision-making and a cornerstone of modern ethical theory.
