Introduction to Utilitarianism

Welcome to one of the most famous and influential theories in the history of ethics! If you have ever thought that the right thing to do is whatever makes the most people happy, then you are already thinking like a Utilitarian. Utilitarianism is a normative ethical theory, which means it provides a "norm" or a standard for how we should act.

In this chapter, we are exploring the idea that morality isn't about following ancient rules or religious laws, but about the consequences of our actions. It is a teleological theory (from the Greek word telos, meaning 'end' or 'purpose'), because it focuses on the end result: happiness.

Quick Context: In your OCR course, this theory sits alongside Natural Law, Situation Ethics, and Kantian Ethics. While those theories might focus on God's laws or duty, Utilitarianism focuses on Utility.

1. The Principle of Utility

The "heart" of Utilitarianism is the Principle of Utility. In simple terms, utility means "usefulness." For Utilitarians, an action is useful if it brings about the maximum amount of happiness and the minimum amount of pain.

This is often called the Greatest Happiness Principle: "The greatest good for the greatest number."

  • Happiness is the only thing that is "good" in itself.
  • Pain is the only thing that is "bad" in itself.
  • Therefore, our moral goal is a simple calculation: \( \text{Utility} = \text{Pleasure} - \text{Pain} \).

Did you know? Utilitarianism is secular (non-religious) in its origins, though some religious people use it to figure out how to best "love their neighbor."

2. Act Utilitarianism

Act Utilitarianism is the "purest" form of the theory. It argues that in every single situation, you should look at the specific act you are about to perform and calculate which option will produce the most happiness.

Key Features:
1. Relative: There are no fixed rules. Stealing might be wrong in one case but right in another if it saves a life and creates more happiness.
2. Consequentialist: Only the outcome matters, not your intentions or the "goodness" of the act itself.
3. Democratic: Everyone’s happiness counts the same. Your own happiness is no more important than a stranger's.

The Hedonic Calculus

How do we actually measure happiness? Act Utilitarians use a tool called the Hedonic Calculus. This is a list of seven criteria used to weigh up the pleasure or pain caused by an action. Don't worry if this seems like a lot to remember; just think of them as "measuring sticks" for a happy life.

  1. Intensity: How strong is the pleasure?
  2. Duration: How long will the pleasure last?
  3. Certainty: How likely is it that the pleasure will actually happen?
  4. Propinquity (Remoteness): How soon will the pleasure happen? (Is it close or far away?)
  5. Fecundity: Will this pleasure lead to other pleasures later on?
  6. Purity: How free from pain is the pleasure? (Does it have nasty side effects?)
  7. Extent: How many people will be affected by the pleasure?

Memory Aid: Use the mnemonic PRICED EF (Purity, Remoteness, Intensity, Certainty, Extent, Duration, Fecundity).

Key Takeaway: Act Utilitarianism is flexible and treats every situation as unique, using the Hedonic Calculus to find the best result.

3. Rule Utilitarianism

Some people found Act Utilitarianism a bit dangerous. For example, if ten people would be very happy to see one innocent person punished for a crime they didn't commit, the Hedonic Calculus might say that is "right."

Rule Utilitarianism was developed to fix this. Instead of looking at individual actions, it looks at general rules. We should follow rules that, if everyone followed them, would lead to the greatest happiness for the community over the long term.

How it works:
- Step 1: Think of a rule (e.g., "Do not lie").
- Step 2: Ask: "If everyone followed this rule, would it create more happiness than the alternative?"
- Step 3: If yes, it becomes a moral rule that we must follow.

Strong vs. Soft Rule Utilitarianism
  • Strong Rule Utilitarians believe we should never break the rules, even if breaking them in one specific case might cause more happiness. They believe the rules are there to protect the long-term good.
  • Soft (or Weak) Rule Utilitarians believe that we should generally follow the rules, but we can break them in extreme situations where a "greater good" is at stake.

Quick Review: Act Utilitarianism is bottom-up (looks at the situation first); Rule Utilitarianism is top-down (looks at the rule first).

4. Evaluation: Is Utilitarianism a Good Theory? (AO2)

To get the high marks in your exam, you need to evaluate. Here are the main strengths and weaknesses you should consider:

Strengths

  • Fairness and Equality: It treats everyone's happiness as equal. It doesn't matter if you are a king or a street sweeper; your "utility" counts for the same.
  • Common Sense: Most people naturally want to be happy and avoid pain. The theory matches our basic human instincts.
  • Flexibility: (Especially for Act Utilitarianism) It allows us to adapt to complex situations where "never lie" might be a bad rule (e.g., hiding someone from a murderer).
  • Objective: The Hedonic Calculus provides a clear, logical way to make decisions without relying on personal feelings or vague religious ideas.

Weaknesses

  • Predicting the Future: Utilitarianism relies on knowing the consequences. However, we can never be 100% sure what will happen in the future.
  • The "Tyranny of the Majority": If the majority of people find pleasure in something cruel (like public executions), Utilitarianism might justify it. It lacks "rights" for the minority.
  • Incommensurability: Is it really possible to "measure" happiness? Is the pleasure of eating an ice cream the same as the pleasure of passing an exam? How do we put a number on it?
  • Too Demanding: If we must always maximize happiness, we could never buy ourselves a treat (like a new phone) because that money would always produce more happiness if given to a charity saving lives.

Common Mistake to Avoid: Don't confuse Utilitarianism with "selfishness." It's not about your happiness; it's about the total happiness of everyone involved.

5. Summary and Comparison

To help you see where Utilitarianism fits in the "Ethics Map," here is a quick comparison:

  1. Natural Law: Rules come from God/Nature (Deontological). Utilitarianism: Rules come from results (Teleological).
  2. Situation Ethics: Focuses on the most loving thing (Agape). Utilitarianism: Focuses on the most happy thing (Utility).
  3. Kantian Ethics: Focuses on duty and logical rules. Utilitarianism: Focuses on pleasure and practical outcomes.

Key Takeaway: Utilitarianism is a practical, result-driven theory that seeks to maximize pleasure and minimize pain, either through individual acts (Act) or general guidelines (Rule).
