All social inequalities which have ceased to be considered expedient, assume the character not of simple inexpediency, but of injustice, and appear so tyrannical, that people are apt to wonder how they ever could have. been tolerated; forgetful that they themselves perhaps tolerate other inequalities under an equally mistaken notion of expediency, the correction of which would make that which they approve seem quite as monstrous as what they have at last learnt to condemn.
John Stuart MillAs long as justice and injustice have not terminated their ever renewing fight for ascendancy in the affairs of mankind, human beings must be willing, when need is, to do battle for the one against the other.
John Stuart Mill... All ideas need to be heard, because each idea contains one aspect of the truth. By examining that aspect, we add to our own idea of the truth. Even ideas that have no truth in them whatsoever are useful because by disproving them, we add support to our own ideas.
John Stuart MillThe industrial economy which divides society absolutely into two portions, the payers of wages and the receivers of them, the first counted by thousands and the last by millions, is neither fit for, nor capable of, indefinite duration: and the possibility of changing this system for one of combination without dependence, and unity of interest instead of organized hostility, depends altogether upon the future developments of the Partnership principle.
