The influential philosopher associated with utilitarianism is John Stuart Mill. Mill, an English philosopher and political economist, expanded the utilitarian concepts originally advanced by Jeremy Bentham, advocating for actions that maximize happiness and reduce suffering. His work, particularly "Utilitarianism" published in 1863, argued that ethical decisions should consider the consequences of actions, focusing on the greatest good for the greatest number. Mill also emphasized qualitative differences in pleasures, advocating for higher intellectual and moral pursuits over mere hedonism. His ideas have had a lasting impact on moral philosophy, ethics, and political theory.
