John Stuart Mill Quotes About Justice

“Over himself, over his own body and mind, the individual is sovereign.”

Mill draws a boundary around mature individual self-government: social power requires justification when it coerces a person in matters that principally concern that person rather than preventing harm to others.

Source note: On Liberty, Chapter I, Project Gutenberg #34901. This sentence follows Mill’s harm-principle formulation and belongs to a political-philosophical argument about the legitimate limits of social and legal interference. It is not a claim that every private action has no effects or obligations toward other people.

“If all mankind minus one, were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind.”

Mill makes the number of people holding an opinion irrelevant to their right to silence dissent: minority speech remains worth protecting even when nearly everyone else believes it wrong.

Source note: On Liberty, Chapter II, Project Gutenberg #34901. Mill’s next argument is epistemic as well as political: suppressing an opinion can deprive everyone of truth or of the clearer understanding created when truth is tested against error.

“Society in equality is its normal state.”

Mill contrasts relations organized around command and obedience with equal association, presenting equality as the normal direction of an improving society.

Source note: The Subjection of Women, discussion of marriage and moral cultivation; the sentence follows Mill’s contrast between older command-and-obedience relations and society among equals.

“The a priori presumption is in favour of freedom and impartiality.”

Mill places the burden of proof on restrictions and unequal privilege rather than treating inherited inequality as self-justifying.

Source note: The Subjection of Women, Chapter I; the line appears in Mill’s argument about where the burden of proof should fall when liberty or equal treatment is restricted.

“What women by nature cannot do, it is quite superfluous to forbid them from doing.”

The argument exposes a contradiction in claims about natural incapacity: if an activity were truly impossible by nature, legal prohibition would be unnecessary.

Source note: The Subjection of Women, Chapter I; Mill argues against using custom and prohibition as evidence of women’s supposed natural limitations.

“The equality of married persons before the law, is not only the sole mode in which that particular relation can be made consistent with justice to both sides.”

Mill applies equal legal standing to marriage, arguing that a just relationship cannot rest on one adult possessing a superior legal status over the other.

Source note: The Subjection of Women, later discussion of marriage; this is a legal and ethical argument about equality within the marital relation.
