Summary of Utilitarianism by John Stuart Mill

John Stuart Mill's Utilitarianism presents and defends the ethical theory that the rightness or wrongness of actions is determined by their tendency to promote happiness or prevent pain, a principle known as the Greatest Happiness Principle. Mill clarifies common misconceptions about utilitarianism, emphasizing that it values not just any pleasure but distinguishes higher (intellectual and moral) pleasures as superior to lower (bodily) ones. He argues that the quality of pleasures must be considered alongside quantity, and that those acquainted with both types of pleasure consistently prefer the higher. Mill acknowledges objections to utilitarianism, such as the claim that happiness is unattainable or that virtue requires renunciation of happiness, but counters that happiness, understood as a balance of pleasures and absence of pain, is both a rational and achievable goal for human life.

Mill further explains that utilitarianism is impartial, requiring individuals to consider the happiness of all affected, not just their own, aligning with the ethical ideals of universal benevolence and the Golden Rule. He stresses that morality is about rules guiding conduct to maximize overall happiness, not about the motives behind actions, which may vary. While some criticize utilitarianism for being too demanding or cold, Mill argues that it recognizes the value of self-sacrifice only insofar as it increases general happiness and that moral evaluation concerns actions rather than personal qualities. Ultimately, Mill presents utilitarianism as a comprehensive and practical moral framework aimed at promoting the greatest good for the greatest number.
