 On Liberty, the essay in which the above quotation appears, is not, writes Mill, the occasion for developing this idea as it relates to “parts of national education.” But in Mill’s view the development of the person can and should be undertaken in concert with an education for citizens. The “mental education” he describes is “in truth, the peculiar training of a citizen, the practical part of the political education of a free people, taking them out of the narrow circle of personal and family selfishness, and accustoming them to the comprehension of joint interests, the management of joint concerns—habituating them to act from public or semi-public motives, and guide their conduct by aims which unite instead of isolating them from one another” (Idem).
