“Judgment is given to men that they may use it. Because it may be used erroneously, are men to be told that they ought not to use it at all? To prohibit what they think pernicious is not claiming exemption from error, but fulfilling the duty incumbent on them, although fallible, of acting on their conscientious conviction. If we were never to act on our opinions, because those opinions ‘lay be wrong, we should leave all our interests uncared for, and all our duties unperformed. An objection which applies to all conduct can be no valid objection to any conduct in particular.”

English philosopher, political economist, and politician

John Stuart Mill was an English philosopher, political economist, and politician. A major figure in nineteenth-century liberal thought, he is known for shaping modern ideas about individual freedom and limits on state and social control. He argued for liberty as a protection for the individual, and is closely associated with the Harm principle. Mill also supported proportional representation, the emancipation of women, and the growth of labour organisations and farm cooperatives. His work is often placed within both classical liberal and social liberal traditions.
