Jeremy Bentham (1748-1832) was an English philosopher and political radical. He is primarily known today for his moral philosophy, especially his principle of utilitarianism, which evaluates action based upon their consequences. The relevant consequences, in particular, are the overall happiness created for everyone affected by the action. Influenced by many Enlightenment thinkers, especially empiricists such as John Locke and David Hume, Bentham developed an ethical theory grounded in a largely empiricist account of both motivation and value according to which what is fundamentally valuable and what ultimately motivates us is pleasure and pain. Happiness, according to Bentham, is thus a matter of experiencing pleasure and lack of pain.
Although he never practiced law, Betham did write a great deal of philosophy of law, spending most of his life critiquing the existing law and strongly advocating legal reform. Throughout his work, he critiques various natural accounts of law that claim, for example, that liberty, rights, and so on exist independent of government. In this way, Bentham arguably developed an early form of what is now often called “legal positivism.” Beyond such critiques, he ultimately maintained that putting his moral theory into consistent practice would yield result in legal theory by providing justification for social, political, and legal institutions.
