On higher and lower pleasures:

It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied. And if the fool, or the pig, is of a different opinion, it is because they only know their own side of the question.

– John Stuart Mill, Utilitarianism, II

On desire:

The only proof capable of being given that an object is visible, is that people actually see it. The only proof that a sound is audible, is that people hear it: and so of the other sources of our experience. In like manner, I apprehend, the sole evidence it is possible to produce that anything is desirable, is that people do actually desire it.

– John Stuart Mill, Utilitarianism, IV

On pleasure and pain:

…desiring a thing and finding it pleasant, aversion to it and thinking of it as painful, are phenomena entirely inseparable, or rather two parts of the same phenomenon; in strictness of language, two different modes of naming the same psychological fact: that to think of an object as desirable (unless for the sake of its consequences), and to think of it as pleasant, are one and the same thing; and that to desire anything, except in proportion as the idea of it is pleasant, is a physical and metaphysical impossibility.

– John Stuart Mill, Utilitarianism, IV

On the ‘harm principle’:

The sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any of their number, is self-protection. … The only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant. He cannot rightfully be compelled to do or forbear because it will be better for him to do so, because it will make him happier, because, in the opinions of others, to do so would be wise, or even right. … The only part of the conduct of any one, for which he is amenable to society, is that which concerns others. In the part which merely concerns himself, his independence is, of right, absolute. Over himself, over his own body and mind, the individual is sovereign.

– John Stuart Mill, On Liberty, I

On the tyranny of majority opinion:

Protection … against the tyranny of the magistrate is not enough: there needs protection also against the tyranny of the prevailing opinion and feeling; against the tendency of society to impose, by other means than civil penalties, its own ideas and practices as rules of conduct on those who dissent from them.

– John Stuart Mill, On Liberty, I

On contradiction and truth:

Complete liberty of contradicting and disproving our opinion, is the very condition which justifies us in assuming its truth for purposes of action; and on no other terms can a being with human faculties have any rational assurance of being right.

– John Stuart Mill, On Liberty, II

On progress and truth:

The beliefs which we have most warrant for, have no safeguard to rest on, but a standing invitation to the whole world to prove them unfounded. If the challenge is not accepted, or is accepted and the attempt fails, we are far enough from certainty still; but we have done the best that the existing state of human reason admits of; we have neglected nothing that could give the truth a chance of reaching us: if the lists are kept open, we may hope that if there be a better truth, it will be found when the human mind is capable of receiving it; and in the meantime we may rely on having attained such approach to truth, as is possible in our own day. This is the amount of certainty attainable by a fallible being, and this the sole way of attaining it.

– John Stuart Mill, On Liberty, II

On diversity:

As it is useful that while mankind are imperfect there should be different opinions, so is it that there should be different experiments of living.

– John Stuart Mill, On Liberty, III

On individuality:

It is not by wearing down into uniformity all that is individual in themselves, but by cultivating it and calling it forth, within the limits imposed by the rights and interests of others, that human beings become a noble and beautiful object of contemplation.

– John Stuart Mill, On Liberty, III

On representative government:

Instead of the function of governing, for which it is radically unfit, the proper office of a representative assembly is to watch and control the government; to throw the light of publicity on its acts; to compel a full exposition and justification of all of them which any one considers questionable; to cinsure them if found condemnable, and, if the men who compose the government abuse their trust, or fulfill it in a manner which conflicts with the deliberate sense of the nation, to expel them from office, and either expressly or virtually appoint their successors.

– John Stuart Mill, Representative Government, V

On prejudice:

So long as an opinion is strongly rooted in the feelings, it gains rather than loses in stability by having a preponderating weight of argument against it. For if it were accepted as a result of argument, the refutation of the argument might shake the solidity of the conviction; but when it rests solely on feeling, the worse it fares in argumentative contest, the more persuaded its adherents are that their feeling must have some deeper ground, which the arguments do not reach.

– John Stuart Mill, The Subjection of Women, I

On the obedience of women:

Men do not want solely the obedience of women, they want their sentiments. … They have therefore put everything in practice to enslave their minds. The masters of all other slaves rely, for maintaining obedience, on fear; either fear of themselves, or religious fears. The masters of women wanted more than simple obedience, and they turned the whole force of education to effect their purpose. All women are brought up from the very earliest years in the belief that their ideal of character is the very opposite to that of men; not self-will, and government by self-control, but submission, and yielding to the control of others. … And, this great means of influence over the minds of women having been acquired, an instinct of selfishness made men avail themselves of it to the utmost as a means of holding women in subjection, by representing to them meekness, submissiveness, and resignation of all individual will into the hands of a man, as an essential part of sexual attractiveness. Can it be doubted that any of the other yokes which mankind have succeeded in breaking, would have subsisted till now if the same means had existed, and had been as sedulously used, to bow down their minds to it? … would not serfs and seigneurs, plebeians and patricians, have been as broadly distinguished at this day as men and women are? and would not all but a thinker here and there, have believed the distinction to be a fundamental and unalterable fact in human nature?

– John Stuart Mill, The Subjection of Women, I

On social institutions:

Whether the institution to be defended is slavery, political absolutism, or the absolutism of the head of a family, we are always expected to judge of it from its best instances; and we are presented with pictures of loving exercise of authority on one side, loving submission to it on the other—superior wisdom ordering all things for the greatest good of the dependents, and surrounded by their smiles and benedictions. All this would be very much to the purpose if any one pretended that there are no such things as good men. Who doubts that there may be great goodness, and great happiness, and great affection, under the absolute government of a good man? Meanwhile, laws and institutions require to be adapted, not to good men, but to bad.

– John Stuart Mill, The Subjection of Women, II

On philosophy:

…speculative philosophy, which to the superficial appears a thing so remote from the business of life and the outward interests of men, is in reality the thing on earth which most influences them, and in the long run overbears every other influence save those which it must itself obey.

– John Stuart Mill, ‘Bentham’
