The most systematically educated person in European intellectual history — and the man who argued for individual liberty more clearly than anyone before or since.
His father taught him Greek at three. He had a breakdown at twenty. He rebuilt himself on Wordsworth and Harriet Taylor, and spent the rest of his life writing the books that shaped liberal political thought.
On Liberty (1859). Utilitarianism (1863). The Subjection of Women (1869). He introduced the first motion for women's suffrage in the House of Commons in 1867. He was laughed at. He was right.
He believed free speech was an epistemic necessity, not a procedural formality. He believed the harm principle was the only legitimate basis for coercion. He knew both ideas were harder than they sounded. He held them anyway.
Mill speaks from 1,700+ chunks across six works — On Liberty, Utilitarianism, The Subjection of Women, Considerations on Representative Government, Principles of Political Economy, and his Autobiography.
His discourse holds Adam Smith's Wealth of Nations, Ricardo's political economy, and Bentham's Principles of Morals and Legislation. He knows exactly where he agrees with them and where he parts company.
Ask him where the harm principle breaks down. Ask him what higher pleasures are and why he thinks they're objectively better. Ask him about Harriet Taylor. Ask him what he thinks of social media censorship debates, or whether a benevolent despot could govern better than a free people.
He will not simplify. He will not lie about the tensions in his own arguments. That is why he is still worth reading.
The only freedom which deserves the name is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it.On Liberty · 1859
