In 1763, while not yet sixteen, he took the degree of A.B. Shortly after this he began his course of Law in Lincoln's Inn, and journeyed back and forth to Oxford to hear Blackstone's Lectures. These lectures were published and read throughout the realm of England and particularly in the American Colonies. These were criticised by the whole school of Cromwell, Milton and such followers as Priestly and others in England and many in the Colonies in America. Young Bentham returned to London and attended as a student the Court of the King's Bench, then presided over by Mansfield, of whom he continued for some years a great admirer. Among the advocates, Dunning's clearness, directness and precision most impressed him. He took the degree of A.M. at the age of 18, the youngest graduate that had been known at the Universities; and in 1772 he was admitted to the Bar. Young Bentham had breathed from infancy, at home, at school, at college and in the Courts, an atmosphere conservative and submissive to authority, yet in the progress of his law studies, he found a striking contrast between the structural imperialism of the British Empire as expounded by Blackstone and others of his day, and the philosophical social state discussed by Aristotle, Plato, Aurelius, the struggling patriots of France, and the new brotherhood, then agitating the colonies of America. His father had hoped to see him Lord-Chancellor, and took great pains to push him forward. But having perceived a shocking contrast between the law as it was under the Church imperial structure and such as he conceived it ought to be, he gradually abandoned the position of a submissive and admiring student and assumed a position among the school of reformers and afterwards the role of sharp critic and indignant denouncer. He heroically suffered privations for several years in Lincoln's Inn garrett, but persevered in study. He devoted some of his time to the study of science. The writings of Hume, Helvetius and others led him to adopt utility as the basis of Morals and Legislation. There had developed two distinct parties in England: The Radicals and Imperialists. The Radicals contended that the foundation of Legislation was that utility which produced the greatest happiness to the greatest number. Blackstone and the Ecclesiastics had adopted the theory of Locke, that the foundation of Legislation was a kind of covenant of mankind to conform to the laws of God and Nature, as interpreted by hereditarily self-constituted rulers. Bentham contended that this was only a vague and uncertain collection of words well adapted to the promotion of rule by dogmatic opinions of the Lords and King and Ecclesiastics in combination well calculated to deprive the people of the benefits of popular government. He conceived the idea of codifying the laws so as to define them in terms of the greatest good to the greatest number, and devoted a large share of the balance of his life to this work.
