 Richard Price (1723–1791) was a prominent dissenting minister and a leading figure in philosophical and political thought in the second half of the eighteenth century. As well as publishing on a wide range of subjects, including ethics, politics, theology, and probability theory, he also greatly advanced work on actuarial tables, which enabled insurers to predict more accurately the life-expectancy of people in their differing circumstances. His passionate commitment to the cause of liberty led him to take a prominent public role in various campaigns, including a remission of the penalties on non-conformists, and in support of both the American and the French revolutions. His defense of the latter prompted a famous reply by Burke, as well as defenses by his friends Paine and Wollstonecraft.
