Understanding Utilitarianism: Act and Rule Variations

Utilitarianism is a philosophical approach to ethics that emphasizes the consequences of actions. It has two distinct types: Act Utilitarianism and Rule Utilitarianism. Understanding these variations helps clarify the moral principles behind utilitarian decision-making. This article will explore the differences between these two forms of utilitarianism and their implications.

Introduction to Utilitarianism

Utilitarianism is a form of consequentialism, which evaluates the morality of an action based on its outcomes. The primary goal of utilitarianism is to maximize overall happiness or utility. It is often articulated in terms of pleasure and pain, but this is not always the case.

Act Utilitarianism

Act Utilitarianism, also known as individual act utilitarianism, focuses on the consequences of individual actions. According to this theory, one should choose an action that maximizes overall happiness or utility in the given circumstances. This means that the ethical assessment of each action is based on the specific outcomes produced.

Key Characteristics:

Concentrates on the utility of individual actions Evaluates the consequences of each specific act Can lead to different conclusions for similar situations based on varying outcomes

For example, if someone is faced with a choice to either help a friend in need or pursue their own pleasure, act utilitarianism would require them to evaluate the specific consequences of each choice. They might conclude that helping a friend would lead to a greater overall utility if the friend's happiness substantially outweighs the personal pleasure they could derive from another action.

Rule Utilitarianism

In contrast, Rule Utilitarianism focuses on the utility of following general rules or principles. According to this theory, one should follow rules that, if universally applied, would maximize overall happiness or utility.

Key Characteristics:

Based on the utility of general rules or principles Considers the long-term effects of following such rules Can lead to consistent moral judgments even in similar situations

A common rule utilitarian example is the prohibition against lying. Rule utilitarianism would argue that lying, as a general rule, should be avoided because its frequent occurrence would lead to less overall utility. In this view, the rule is not about the utility of lying in specific instances but about the overall consequences of a rule that forbids lying.

Historical Context and Criticisms

Historically, philosopher J.J. Smart argued in his 1956 article "Extreme and Restricted Utilitarianism" that Rule Utilitarianism either collapses into Act Utilitarianism or becomes a form of rule-worship. His argument revolves around the practical implications of following strict rules.

Smart's Argument:

Imagine you are a ship captain with a navigation book that covers all known scenarios. Suddenly, a situation arises where the book's advice is incorrect. According to Rule Utilitarianism, you should follow the book because it has proven correct in a vast majority of cases. However, in this specific instance, the book is wrong. Following the book in this situation would be irrational because it prioritizes the reliability of a rule over the current circumstances.

In response to this, one might argue that this inconsistency suggests a deviation from strict rule-following. Smart suggests that allowing exceptions based on specific circumstances reintroduces the flexibility of act utilitarianism, where actions are judged on their immediate outcomes. This validates the idea that the rule can be updated based on the current situation, implying that rigid adherence to a rule is actually not a true rule in the sense of utilitarianism.

Conclusion

Both Act Utilitarianism and Rule Utilitarianism offer distinct paths to ethical decision-making. While Act Utilitarianism focuses on the specific outcomes of individual actions, Rule Utilitarianism seeks to create a set of broadly beneficial rules. Understanding the nuances between these approaches can provide valuable insights into the complex interplay between ethics and practical decision-making.
