Executive Summary
John Stuart Mill's 'Utilitarianism' (1863) is a foundational text in ethical philosophy that defends the 'Greatest Happiness Principle.' Mill defines morality through a consequentialist lens, arguing that actions are right insofar as they promote happiness—defined as pleasure and the absence of pain—and wrong as they produce the reverse. Originally published as a series of articles in Fraser's Magazine in 1861 before being collected as a book in 1863, the work sought to refine the 'calculus of pleasure' established by his predecessor Jeremy Bentham by introducing qualitative distinctions between different types of pleasure.
Key Themes
The Greatest Happiness Principle
The core axiom that 'actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness' (Source: SparkNotes, Mill Ch. 2).
Higher vs. Lower Pleasures
Mill differentiates between 'higher' (intellectual, moral, and aesthetic) and 'lower' (sensory) pleasures, arguing that those who have experienced both will prefer the higher faculties even if they come with greater dissatisfaction (Source: Stanford Encyclopedia of Philosophy).
The Role of Justice
Mill argues that the sentiment of justice is not an independent moral standard but is actually rooted in utility, where 'rights' are simply rules that society must protect to ensure long-term collective happiness (Source: Internet Encyclopedia of Philosophy).
Rule vs. Act Utilitarianism
A major theme in scholarly review is whether Mill advocates for 'act utilitarianism' (judging each individual action) or 'rule utilitarianism' (following general rules that maximize utility) (Source: ResearchGate).
