John Stuart Mill (180673)
If it were felt that the free development of individuality is one of the leading essentials of well-being; that it is not only a coordinate element with all that is designated by the terms civilisation, instruction, education, culture, but is itself a necessary part and condition of all those things; there would be no danger that liberty should be undervalued.
JOHN STUART MILL, On Liberty, ed. David Spitz, chapter 3, p. 54 (1975). Originally published in 1859.
