Jeremy Bentham was an English jurist, philosopher, and legal and social reformer. He was a political radical, and a leading theorist in Anglo-American philosophy of law. He is best known for his advocacy of utilitarianism, for the concept of animal rights, and his opposition to the idea of natural rights, with his oft-quoted statement that the idea of such rights is "nonsense upon stilts." He also influenced the development of welfarism.
He became known as one of the most influential of the utilitarians, through his own work and that of his students. These included his secretary and collaborator on the utilitarian school of philosophy, James Mill; James Mill's son John Stuart Mill; and several political leaders including Robert Owen, who later became a founder of socialism. He is also considered the godfather of University College London.
