"All that has been said of the importance of individuality of character, and diversity in opinions and modes of conduct, involves, as of the same unspeakable importance, diversity of education. A general State education is a mere contrivance for moulding people to be exactly like one another; and as the mould in which it casts them is that which pleases the predominant power in the government . . . in proportion as it is efficient and successful, it establishes a despotism over the mind, leading by natural tendency to one over the body."
-John Stuart Mill, 1859, quoted here
