A pupil from whom nothing is ever demanded which he cannot do, never does all he can.

Source identified6
Where there is no inducement to exceed a certain minimum, the minimum comes to be the maximum.

“Where there is no inducement to exceed a certain minimum, the minimum comes to be the maximum.”

Mill warns that systems which reward only a minimum standard tend to normalize that floor as the practical ceiling, reducing incentives for greater effort or attainment.

Source details

Considerations on Representative Government (1861), Chapter XIV, “Of the Executive in a Representative Government,” Project Gutenberg #5669. During Mill’s discussion of first appointments to the permanent public service and competitive examinations, he warns that where only a minimum is required, that minimum tends to become the practical maximum. The sentence remains institutional analysis of public-service selection and education, not generic employee-management advice.

Source identified7
valuable acquisitions are only to be retained by the continuation of the same energies which gained them.

“valuable acquisitions are only to be retained by the continuation of the same energies which gained them.”

Mill argues that gains decay when the habits of care, thought and exertion that produced them are abandoned, making preservation itself an active form of progress.

Source details

Considerations on Representative Government (1861), Chapter II, “The Criterion of a Good Form of Government,” Project Gutenberg #5669. Mill argues that preserving valuable social acquisitions requires continued energy, care and thoughtfulness rather than assuming gains maintain themselves. This is nineteenth-century political and institutional argument, not an empirical productivity or self-help guarantee.

There is no act which more imperatively requires to be performed under a strong sense of individual responsibility than the nomination to employments.

“There is no act which more imperatively requires to be performed under a strong sense of individual responsibility than the nomination to employments.”

Source details

Considerations on Representative Government (1861), Chapter V, “Of the Proper Functions of Representative Bodies,” Project Gutenberg #5669. This is historical constitutional and administrative theory rather than a current hiring standard.

Source identified9
Genius can only breathe freely in an atmosphere of freedom.

“Genius can only breathe freely in an atmosphere of freedom.”

Original thought needs enough freedom to resist social moulds; creativity weakens when unusual minds are compressed into approved patterns.

Source details

Source identified10
He who chooses his plan for himself, employs all his faculties.

“He who chooses his plan for himself, employs all his faculties.”

Choosing for oneself exercises observation, reasoning, discrimination, and self-command in ways that passive imitation does not.

Source details

On Liberty, Chapter III, in Mill’s discussion of individuality and self-directed choice.

Source identified11
He who does anything because it is the custom, makes no choice.

“He who does anything because it is the custom, makes no choice.”

Mill argues that genuine individuality requires active judgment rather than automatic conformity: a person develops the faculties of choice only by deciding for reasons he has actually examined.

Source details

On Liberty, Chapter III, “Of Individuality, as One of the Elements of Well-Being”; Project Gutenberg #34901. The sentence follows Mill's list of perception, judgment, discriminative feeling, mental activity and moral preference as faculties exercised through making a choice.

Source identified12
He who knows only his own side of the case, knows little of that.

“He who knows only his own side of the case, knows little of that.”

Understanding a position requires serious contact with competing arguments; familiarity with only one side can produce confidence without real comprehension.

Source details

Source identified13
Over himself, over his own body and mind, the individual is sovereign.

“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 details

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.

Source identified14
The despotism of custom is everywhere the standing hindrance to human advancement.

“The despotism of custom is everywhere the standing hindrance to human advancement.”

Custom can become an obstacle when conformity is treated as an answer in itself; improvement requires room to question inherited patterns and try better ones.

Source details

On Liberty, Chapter III; Mill describes custom as an enduring opponent of the spirit of liberty, progress and improvement.

Source identified16
He who lets the world, or his own portion of it, choose his plan of life for him, has no need of any other faculty than the ape-like one of imitation.

“He who lets the world, or his own portion of it, choose his plan of life for him, has no need of any other faculty than the ape-like one of imitation.”

A life copied from convention leaves important human faculties unused; choosing deliberately requires observation, judgment and firmness.

Source details

On Liberty, Chapter III; Mill contrasts imitation with actively choosing one’s own plan of life.

Source identified17
A person whose desires and impulses are his own—are the expression of his own nature, as it has been developed and modified by his own culture—is said to have a character.

“A person whose desires and impulses are his own—are the expression of his own nature, as it has been developed and modified by his own culture—is said to have a character.”

Character is connected with developed individuality rather than passive conformity: a person’s motives should reflect cultivated judgment rather than borrowed scripts.

Source details

Source identified18
The only freedom which deserves the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it.

“The only freedom which deserves the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it.”

Source identified19
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.

“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 details

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.

Source identified20

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

“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 details

The Subjection of Women (1869), Chapter I, printed page 48, Project Gutenberg #27083. Mill argues that if an activity were truly contrary to women’s nature, legal or social prohibition would be superfluous; the sentence belongs to his case for free development and open competition.

Source identified23
The question rests with women themselves—to be decided by their own experience, and by the use of their own faculties.

“The question rests with women themselves—to be decided by their own experience, and by the use of their own faculties.”

Mill argues that women themselves must test capacities and choices through experience rather than having those possibilities defined in advance by others.

Source details

“Human beings are no longer born to their place in life, and chained down by an inexorable bond to the place they are born to.”

Source details

The Subjection of Women (1869), Chapter II, printed page 78, Project Gutenberg #27083. Mill argues that equality of married persons before the law is required for justice to both sides and for marriage to become a school of moral cultivation rather than legal subordination.

Source identified26
He who would rightly appreciate the worth of personal independence as an element of happiness, should consider the value he himself puts upon it as an ingredient of his own.

“He who would rightly appreciate the worth of personal independence as an element of happiness, should consider the value he himself puts upon it as an ingredient of his own.”

It is better to be a human being dissatisfied than a pig satisfied.

Source details
