Ethics class is moving fast, and utilitarianism can feel slippery — is it just "do whatever makes people happy"? Is it always right to sacrifice one person to save five? If your teacher assigned Bentham or Mill and you're not sure where to start, this guide cuts straight to what you need to know.

**Utilitarianism: The Greatest Good for the Greatest Number** is a focused, no-filler primer covering the core ideas of classical utilitarianism in plain language. It walks you through Bentham's hedonic calculus and Mill's distinction between higher and lower pleasures, then explains the difference between act and rule utilitarianism with worked examples that show exactly how the two versions can point in opposite directions. You'll see utilitarian reasoning applied to the trolley problem, the transplant surgeon case, and a real-world policy scenario — so the logic isn't just abstract.

The guide also takes the objections seriously. Justice, demandingness, moral integrity, and the practical limits of calculating consequences are all laid out clearly, along with how utilitarians push back. A final section places the theory alongside deontology and virtue ethics and connects it to contemporary movements like effective altruism.

This is a **bentham and mill ethics study guide** in the TLDR tradition: 10–20 pages, written for high school and early college students who need to understand the material, not just memorize it. Whether you're prepping for an exam, writing a paper, or trying to follow along in class, this primer gives you a solid footing fast.

If you need a clear, honest introduction to one of the most influential moral theories ever developed, pick this up.

• Explain the core principle of utility and what 'greatest good for the greatest number' actually means
• Distinguish Bentham's quantitative hedonism from Mill's qualitative version, and act from rule utilitarianism
• Apply utilitarian reasoning to concrete moral dilemmas like the trolley problem
• Identify and articulate the major objections to utilitarianism (justice, demandingness, calculation problems)
• Compare utilitarianism to deontology and virtue ethics at an introductory level

1. 1. What Utilitarianism Actually Says
   Introduces the principle of utility, the idea of consequences as the basis of morality, and clears up common misreadings of 'greatest good for the greatest number.'
2. 2. Bentham, Mill, and the Hedonic Calculus
   Traces the theory from Jeremy Bentham's quantitative calculation of pleasure and pain to John Stuart Mill's distinction between higher and lower pleasures.
3. 3. Act vs. Rule Utilitarianism
   Explains the split between evaluating individual actions and evaluating rules, with worked examples showing how the two versions can give different answers.
4. 4. Applying Utilitarianism: Trolley Problems and Real Cases
   Walks through the trolley problem, transplant surgeon case, and one real-world policy example to show utilitarian reasoning in action.
5. 5. The Strongest Objections
   Presents the major critiques: the justice objection, the demandingness objection, the calculation problem, and the integrity objection — with how utilitarians try to respond.
6. 6. Where Utilitarianism Fits in Ethics
   Places utilitarianism alongside deontology and virtue ethics, notes its influence on modern movements like effective altruism, and points to what to study next.
