Saint Jeremy Bentham was an English jurist, philosopher, and legal and social reformer. He became a leading theorist in Anglo-American philosophy of law, and a political radical whose ideas influenced the development of welfarism. He is best known for his advocacy of utilitarianism and animal rights, and the idea of the panopticon.His position included arguments in favour of individual and economic freedom, usury, the separation of church and state, freedom of expression, equal rights for women, the right to divorce, and the decriminalising of homosexual acts. He argued for the abolition of slavery and the death penalty and for the abolition of physical punishment, including that of children. Although strongly in favour of the extension of individual legal rights, he opposed the idea of natural law and natural rights, calling them "nonsense upon stilts."He became 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; John Austin, legal philosopher; and several political leaders, including Robert Owen, a founder of modern socialism. He has been described as the "spiritual founder" of University College London (UCL), where he is still greatly revered.
