This paper returns to J. S. Mill to draw out democratic conceptions of education and equality that challenge still-current conceptions of intractable human inequalities. Mill acknowledges that individuals differ in abilities. Nonetheless, he develops a broad conception of ‘education for freedom’ and insists that only ‘wretched social arrangements’ prevent virtually all people from exercising capacities for self-government in citizenship, marriage, and industry. In the same breath, he qualifies his democratic egalitarianism with reference to a sub-class of working people whose ‘low moral qualities’ leave them unfit for such self-government. Modern liberal states largely dismiss Mill's more radical democratic impulse. Meanwhile, they reiterate and refine his exclusionary one through new practices for constructing and managing inequalities – for example, IQ tests, educational ‘tracking’, and social science categories like the ‘underclass’. I reconsider this divided legacy of Mill's egalitarianism as a basis for rethinking the limits of today's ‘meritocratic’ egalitarianism.
