Mill (1806-1873) began to learn Greek at three and Latin at eight. By the age of fourteen he had read most of the Greek and Latin classics, had made a wide survey of history, had done extensive work in logic and mathematics, and had mastered the basics of economic theory. This education was undertaken according to the principle of Bentham's associationist psychology, and aimed to make of the younger Mill a leader in views of the philosophical radicals...
At fifteen he undertook the study of Bentham's various fragments on the theory of legal evidence. These had an inspiring influence on him, fixing in him his life-long goal of reforming the world in the interest of human well-being. At eighteen he spent considerable time and effort at editing these manuscripts into the long coherent treatise that they became in his hands. Guided by his father he threw himself into the work of the philosophical radicals, and began an active literary career. Shortly thereafter, in 1823, his father secured him a junior position in the East India Company. He rose in the ranks, eventually to occupy his father's position of Chief Examiner. A visit to France in 1820 had made Mill thoroughly fluent in the language, and he became a life-long student of French thought and history.
In 1826, Mill suffered a sudden attack of intense depression. This lasted for many months. He continued his work, and indeed even his political activities, but internally he felt that his former goals were without worth. He came to believe that his capacity for emotion had been severely weakened by his father's rigorous training in analysis. His intellect had been educated but not his feelings. In the reading of Wordsworth's poetry he found something of the cure that he needed, and the depression gradually disappeared... SEP

Which finds no natural outlet or relief
In word, or sigh, or tear."
And hope without an object cannot live."
