On Liberty is a defence of individual freedom against unnecessary interference by governments and society. Mill argues that power should normally be used against an adult only to prevent harm to other people. This principle does not mean that every action is acceptable; conduct that injures others may be regulated. However, personal choices, beliefs and ways of living should remain free when they primarily concern the individual. Mill strongly defends freedom of speech because an unpopular opinion may be true, partly true or useful in exposing weaknesses in accepted beliefs. He also warns against the “tyranny of the majority,” through which social pressure can silence individuality without formal laws. Human progress, in Mill’s view, depends upon open discussion, experimentation and diverse ways of life.
- The harm principle: Coercion is normally justified only to prevent harm to other people, not merely because society dislikes someone’s behaviour.
- Self-regarding actions: Adults should generally control decisions concerning their own lives, provided they do not violate the rights of others.
- Freedom of thought: People must be free to form beliefs without punishment or enforced intellectual conformity.
- Freedom of expression: Even offensive or unpopular opinions deserve protection unless their expression directly produces serious harm.
- An unpopular view may be true: Silencing an opinion assumes that the majority cannot be mistaken.
- A false opinion may contain partial truth: Debate may combine different parts of truth that are divided between opposing positions.
- Unchallenged truth becomes a dead belief: Even a correct idea loses meaning when people repeat it without understanding the arguments behind it.
- Individuality supports progress: Original people and unusual lifestyles can discover better ways of living.
- Social tyranny is dangerous: Customs, public shame and majority pressure may control individuals more deeply than government laws.
- Famous quotation: “If all mankind minus one were of one opinion…” the one dissenter should not be silenced.
