How did James Mill educate John Stuart Mill during his childhood?

John Stuart Mill was educated exclusively by his father, James Mill, a strict disciplinarian who fostered a close intellectual association with his son. From his earliest days, the younger Mill spent significant time in his father’s study and accompanied him on walks, where he absorbed his father’s speculative opinions and methods of argumentation.1

His education was rigorous and accelerated:
* Languages and Literature: By age eight, he had read Aesop’s Fables, Xenophon’s Anabasis, and the works of Herodotus in the original Greek. By age 10, he could read Plato and Demosthenes with ease.1
* Mathematics and Sciences: He began Latin, geometry, and algebra at age eight.1
* Advanced Studies: By age 12, he studied Scholastic logic and Aristotle, followed by political economy and the works of Adam Smith and David Ricardo.1

While this training was effective, it placed a significant strain on his constitution and lacked natural, unforced development.1
