3.4 The Utility Monster and the Principle of Diminishing Marginal Utility

Introduction to Utilitarianism

  • Discusses the philosophical concept of utilitarianism, particularly through Bentham's perspective.

  • Introduces the idea of a "utility monster" to visualize the implications of utilitarianism.

Utility Monster Concept

  • Definition: A hypothetical individual with a disproportionately high capacity to enjoy goods or services.

  • Hypothetical Scenario:

    • If a utility monster can derive more happiness from resources than normal people, utilitarianism suggests giving all resources to the monster to maximize overall happiness.

    • This raises ethical questions about resource distribution among individuals with varying capacities for pleasure.

Comparisons with Depressed Individuals

  • Example: Two individuals are offered $5.

    • One is depressed and dismisses the amount.

    • The other is grateful for it.

  • Conclusion drawn: To maximize societal utility, the $5 should go to the person likely to appreciate it more.

Critiques of Utilitarianism

  • Concerns: Resource Allocation

    • Criticism argues that resources spent on helping handicapped individuals might lead to less overall happiness than spending those on able-bodied individuals who would derive more utility from them.

  • Implication: In a strict utilitarian framework, it might seem justifiable to neglect or even harm disadvantaged individuals for the sake of overall happiness.

Connection to Historical Issues

  • Makes connections to historical events, like the Holocaust.

  • Eichmann Problem: Argues that if the act of extermination brings more perceived utility to a group than the suffering it inflicts, it may not seem wrong from a utilitarian view.

Diminishing Marginal Utility

  • Concept Explanation: As consumption increases, the additional satisfaction (utility) gained from each additional unit decreases.

  • Example In Action:

    • Giving a newly car-less person one Porsche makes them much happier, while several more Porsches yield increasingly less additional satisfaction.

  • Utility Curve: Utility increases but flattens as more goods are acquired, suggesting a limit to pleasure.

Economic Principles

  • Diminishing marginal utility is a key concept in economics. It informs how goods are valued and consumed.

  • Indifference Curves: The shape of indifference curves reflects the principle of diminishing marginal utility.

Reflection on Real-life Scenarios

  • Discusses the diminishing utility of common experiences (e.g., drinking beer).

    • After a certain intake, negative consequences (e.g., inebriation, health risks) outweigh the pleasure, illustrating diminishing returns.

  • Considers occasional exceptions to this principle but emphasizes its overall reliability.

Implications for Government and Society

  • Questions the necessity of government in a deterministic utilitarian framework.

  • If individuals are driven purely by pleasure and pain avoidance with no choice, what role would government serve?

  • Poses this question for further discussion and exploration in future lessons.
