Is the right thing to do simply whatever creates the most happiness right now?

In short: Act utilitarianism argues that your moral duty is to maximize pleasure and minimize pain in every specific situation. By focusing solely on the consequences of individual actions, this theory challenges traditional moral rules, forcing us to weigh the immediate outcome of our choices against the happiness of everyone involved.

At its core, utilitarianism is a consequentialist framework, meaning the morality of an action is determined entirely by its results. Act utilitarianism, specifically, evaluates each individual act based on whether it produces the best possible outcome in that exact moment. Proponents like Jeremy Bentham and John Stuart Mill argued that happiness—defined as the presence of pleasure and the absence of pain—is the only intrinsic good. Consequently, they believed that we ought to act to maximize this balance for everyone affected by our choices.

Bentham famously proposed that a 'hedonic calculus' could theoretically measure these outcomes by summing units of pleasure and pain. While modern thinkers acknowledge that such precise calculation is difficult, the theory remains a powerful tool for evaluating social practices. It stands in direct opposition to deontological ethics, which judges actions based on rules or duties regardless of their consequences, and to egoism, which prioritizes personal self-interest over the collective good.

The theory faces significant criticism, particularly regarding its potential to justify acts that violate common moral intuitions. Critics point out that if an act of theft or lying could produce a net gain in happiness in a specific instance, act utilitarianism might label it as morally required. More extreme objections suggest that even acts like torture could be permissible if they generated enough happiness. These concerns led some philosophers to develop 'rule utilitarianism,' which evaluates actions based on whether they follow a general rule that, if universally practiced, would maximize overall happiness, thereby attempting to avoid the inconsistencies of judging every act in isolation.
