An Essay Concerning Human Understanding (1689)
Variant: The actions of men are the best interpreters of their thoughts.

As quoted in "Hand Book : Caution and Counsels" in The Common School Journal Vol. 5, No. 24 (15 December 1843) by Horace Mann, p. 371
Context: This is that which I think great readers are apt to be mistaken in; those who have read of everything, are thought to understand everything too; but it is not always so. Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours. We are of the ruminating kind, and it is not enough to cram ourselves with a great load of collections; unless we chew them over again, they will not give us strength and nourishment.

Some Thoughts Concerning Education (1693)
Context: The Indians, whom we call barbarous, observe much more decency and civility in their discourses and conversation, giving one another a fair silent hearing till they have quite done; and then answering them calmly, and without noise or passion. And if it be not so in this civiliz'd part of the world, we must impute it to a neglect in education, which has not yet reform'd this antient piece of barbarity amongst us.

Sec. 102
Some Thoughts Concerning Education (1693)
Context: Begin therefore betimes nicely to observe your son's temper; and that, when he is under least restraint, in his play, and as he thinks out of your sight. See what are his predominate passions and prevailing inclinations; whether he be fierce or mild, bold or bashful, compassionate or cruel open or reserv'd, &c. For as these are different in him, so are your methods to be different, and your authority must hence take measures to apply itself different ways to him. These native propensities, these prevalencies of constitution, are not to be cur'd by rules, or a direct contest, especially those of them that are the humbler or meaner sort, which proceed from fear, and lowness of spirit: though with art they may be much mended, and turn'd to good purposes. But this be sure, after all is done, the bypass will always hang on that side that nature first plac'd it: And if you carefully observe the characters of his mind, now in the first scenes of his life, you will ever after be able to judge which way his thoughts lean, and what he aims at even hereafter, when, as he grows up, the plot thickens, and he puts on several shapes to act it.

Sec. 94
Some Thoughts Concerning Education (1693)
Context: The scene should be gently open'd, and his entrance made step by step, and the dangers pointed out that attend him from several degrees, tempers, designs, and clubs of men. He should be prepared to be shocked by some, and caress'd by others; warned who are like to oppose, who to mislead, who to undermine him, and who to serve him. He should be instructed how to know and distinguish them; where he should let them see, and when dissemble the knowledge of them and their aims and workings.

Context: To this I answer: That force is to be opposed to nothing, but to unjust and unlawful force. Whoever makes any opposition in any other case, draws on himself a just condemnation, both from God and man…

Book IV, Ch. 19 : Of Enthusiasm (Chapter added in the fourth edition).
Variant paraphrase, sometimes cited as a direct quote: One unerring mark of the love of truth is not entertaining any proposition with greater assurance than the proofs it is built upon will warrant.
As paraphrased in Peter's Quotations : Ideas for our Time (1979) by Laurence J. Peter, p. 500; also in The Demon-Haunted World : Science as a Candle in the Dark (1994) by Carl Sagan, p. 64
An Essay Concerning Human Understanding (1689)
Context: He that would seriously set upon the search of truth, ought in the first place to prepare his mind with a love of it. For he that loves it not, will not take much pains to get it; nor be much concerned when he misses it. There is nobody in the commonwealth of learning who does not profess himself a lover of truth: and there is not a rational creature that would not take it amiss to be thought otherwise of. And yet, for all this, one may truly say, that there are very few lovers of truth, for truth's sake, even amongst those who persuade themselves that they are so. How a man may know whether he be so in earnest, is worth inquiry: and I think there is one unerring mark of it, viz. The not entertaining any proposition with greater assurance than the proofs it is built upon will warrant. Whoever goes beyond this measure of assent, it is plain receives not the truth in the love of it; loves not truth for truth's sake, but for some other bye-end.

Sec. 71; Note: Here Locke quotes Juvenal
Some Thoughts Concerning Education (1693)
Context: He that will have his son have a respect for him and his orders, must himself have a great reverence for his son. Maxima debetur pueris reverentia [The greatest respect is owed to the children].

Sec. 73
Some Thoughts Concerning Education (1693)
Context: None of the things they learn, should ever be made a burthen to them, or impos's on them as a task. Whatever is so proposed, presently becomes irksome; the mind takes an aversion to it, though before it were a thing of delight or indifferency. Let a child but be ordered to whip his top at a certain time every day, whether he has or has not a mind to it; let this be but requir'd of him as a duty, wherein he must spend so many hours morning and afternoon, and see whether he will not soon be weary of any play at this rate. Is it not so with grown men?

Sec. 84
Some Thoughts Concerning Education (1693)
Context: Beating is the worst, and therefore the last means to be us'd in the correction of children, and that only in the cases of extremity, after all gently ways have been try'd, and proved unsuccessful; which, if well observ'd, there will very seldom be any need of blows.

Sec. 116
Some Thoughts Concerning Education (1693)
Context: All the entertainment and talk of history is nothing almost but fighting and killing: and the honour and renown that is bestowed on conquerers (who for the most part are but the great butchers of mankind) farther mislead growing youth, who by this means come to think slaughter the laudible business of mankind, and the most heroick of virtues. By these steps unnatural cruelty is planted in us; and what humanity abhors, custom reconciles and recommends to us, by laying it in the way to honour. Thus, by fashioning and opinion, that comes to be a pleasure, which in itself neither is, nor can be any.

First Treatise of Government
Two Treatises of Government (1689)
Context: The imagination is always restless and suggests a variety of thoughts, and the will, reason being laid aside, is ready for every extravagant project; and in this State, he that goes farthest out of the way, is thought fittest to lead, and is sure of most followers: And when Fashion hath once Established, what Folly or craft began, Custom makes it Sacred, and 'twill be thought impudence or madness, to contradict or question it. He that will impartially survey the Nations of the World, will find so much of the Governments, Religion, and Manners brought in and continued amongst them by these means, that they will have but little Reverence for the Practices which are in use and credit amongst Men.

Sec. 141
Some Thoughts Concerning Education (1693)
Context: The next good quality belonging to a gentleman, is good breeding [manners]. There are two sorts of ill-breeding: the one a sheepish bashfulness, and the other a mis-becoming negligence and disrespect in our carriage; both of which are avoided by duly observing this one rule, not to think meanly of ourselves, and not to think meanly of others.

Sec. 81
Some Thoughts Concerning Education (1693)
Context: The foundations on which several duties are built, and the foundations of right and wrong from which they spring, are not perhaps easily to be let into the minds of grown men, not us'd to abstract their thoughts from common received opinions. Much less are children capable of reasonings from remote principles. They cannot conceive the force of long deductions. The reasons that move them must be obvious, and level to their thoughts, and such as may be felt and touched. But yet, if their age, temper, and inclination be consider'd, they will never want such motives as may be sufficient to convince them.

Sec. 98
Some Thoughts Concerning Education (1693)
Context: He will better comprehend the foundations and measures of decency and justice, and have livelier, and more lasting impressions of what he ought to do, by giving his opinion on cases propos'd, and reasoning with his tutor on fit instances, than by giving a silent, negligent, sleepy audience to his tutor's lectures; and much more than by captious logical disputes, or set declamations of his own, upon any question. The one sets the thoughts upon wit and false colours, and not upon truth; the other teaches fallacy, wrangling, and opiniatry; and they are both of them things that spoil the judgment, and put a man out of the way of right and fair reasoning; and therefore carefully to be avoided by one who would improve himself, and be acceptable to others.

Sec. 105
Some Thoughts Concerning Education (1693)
Context: Another thing wherein they shew their love of dominion, is, their desire to have things to be theirs: They would have propriety and possession, pleasing themselves with the power which that seems to give, and the right that they thereby have, to dispose of them as they please. He that has not observ's these two humours working very betimes in children, has taken little notice of their actions: And he who thinks that these two roots of almost all the injustice and contention that so disturb human life, are not early to be weeded out, and contrary habits introduc'd, neglects the proper season to lay the foundations of a good and worthy man.

§ 243
The Reasonableness of Christianity (1695)
Context: The greatest part of mankind want leisure or capacity for demonstration, nor can carry a train of proofs, which in that way they must always depend upon for conviction, and cannot be required to assent to till they see the demonstration. Wherever they stick, the teachers are always put upon proof, and must clear the doubt by a thread of coherent deductions from the first principle, how long or how intricate soever that be. And you may as soon hope to leave all the day labourers and tradesmen, the spinsters and dairy-maids, perfect mathematicians, as to have them perfect in ethics this way: having plain commands is the sure and only course to bring them to obedience and practice: the greatest part cannot know, and therefore they must believe. And I ask, whether one coming from heaven in the power of God, in full and clear evidence and demonstration of miracles, giving plain and direct rules of morality and obedience, be not likelier to enlighten the bulk of mankind, and set them right in their duties, and bring them to do them, than by reasoning with them from general notions and principles of human reason?

Sec. 95
Some Thoughts Concerning Education (1693)
Context: A father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in. For it is easy to observe, that many young men continue longer in thought and conversation of school-boys than otherwise they would, because their parents keep them at that distance, and in that low rank, by all their carriage to them.

Sec. 73
Some Thoughts Concerning Education (1693)
Context: Children have as much mind to shew that they are free, that their own good actions come from themselves, that they are absolute and independent, as any of the proudest of you grown men, think of them as you please.

Sec. 117
Some Thoughts Concerning Education (1693)
Context: Children should not be suffer'd to lose the consideration of human nature in the shufflings of outward conditions. The more they have, the better humor'd they should be taught to be, and the more compassionate and gentle to those of their brethren who are placed lower, and have scantier portions. If they are suffer'd from their cradles to treat men ill and rudely, because, by their father's title, they think they have a little power over them, at best it is ill-bred; and if care be not taken, will by degrees nurse up their natural pride into an habitual contempt of those beneath them. And where will that probably end but in oppression and cruelty?

Sec. 145
Some Thoughts Concerning Education (1693)
Context: Though the managing ourselves well in this part of our behavior has the name good-breeding, as if a peculiar effect of education; yet... young children should not be much perplexed about it... Teach them humility, and to be good-natur'd, if you can, and this sort of manners will not be wanting; civility being in truth nothing but a care not to shew any slighting or contempt of any one in conversation.

Sec. 131
Some Thoughts Concerning Education (1693)
Context: Lying... is so ill a quality, and the mother of so many ill ones that spawn from it, and take shelter under it, that a child should be brought up in the greatest abhorrence of it imaginable. It should be always spoke of before him with the utmost detestation, as a quality so wholly inconsistent with the name and character of a gentleman, that no body of any credit can bear the imputation of a lie; a mark that is judg'd in utmost disgrace, which debases a man to the lowest degree of a shameful meanness, and ranks him with the most contemptible part of mankind and the abhorred rascality; and is not to be endured in any one who would converse with people of condition, or have any esteem or reputation in the world.

Epitaph, as translated from the Latin.
Context: Stop Traveller! Near this place lieth John Locke. If you ask what kind of a man he was, he answers that he lived content with his own small fortune. Bred a scholar he made his learning subservient only to the cause of truth. This thou will learn from his writings, which will show thee everything else concerning him, with greater truth, than the suspect praises of an epitaph. His virtues, indeed, if he had any, were too little for him to propose as matter of praise to himself, or as an example to thee. Let his vices be buried together. As to an example of manners, if you seek that, you have it in the Gospels; of vices, to wish you have one nowhere; if mortality, certainly, (and may it profit thee), thou hast one here and everywhere.

Context: You must do nothing before him, which you would not have him imitate. If any thing escape you, which you would have pass as a fault in him, he will be sure to shelter himself under your example, and shelter himself so as that it will not be easy to come at him, to correct it in him the right way.

Sec. 82
Some Thoughts Concerning Education (1693)
Context: Of all the ways whereby children are to be instructed, and their manners formed, the plainest, easiest, and most efficacious, is, to set before their eyes the examples of those things you would have them do, or avoid; which, when they are pointed out to them, in the practice of persons within their knowledge, with some reflections on their beauty and unbecomingness, are of more force to draw or deter their imitation, than any discourses which can be made to them.

Sec. 81

Book IV, Ch. 16, sec. 4
An Essay Concerning Human Understanding (1689)
Context: For where is the man that has incontestable evidence of the truth of all that he holds, or of the falsehood of all he condemns; or can say that he has examined to the bottom all his own, or other men's opinions? The necessity of believing without knowledge, nay often upon very slight grounds, in this fleeting state of action and blindness we are in, should make us more busy and careful to inform ourselves than constrain others. At least, those who have not thoroughly examined to the bottom all their own tenets, must confess they are unfit to prescribe to others; and are unreasonable in imposing that as truth on other men's belief, which they themselves have not searched into, nor weighed the arguments of probability, on which they should receive or reject it. Those who have fairly and truly examined, and are thereby got past doubt in all the doctrines they profess and govern themselves by, would have a juster pretence to require others to follow them: but these are so few in number, and find so little reason to be magisterial in their opinions, that nothing insolent and imperious is to be expected from them: and there is reason to think, that, if men were better instructed themselves, they would be less imposing on others.

Context: A criminal who, having renounced reason … hath, by the unjust violence and slaughter he hath committed upon one, declared war against all mankind, and therefore may be destroyed as a lion or tyger, one of those wild savage beasts with whom men can have no society nor security. And upon this is grounded the great law of Nature, "Whoso sheddeth man's blood, by man shall his blood be shed."

Some Thoughts Concerning Education (1693)
Context: They should always be heard, and fairly and kindly answer'd, when they ask after any thing they would know, and desire to be informed about. Curiosity should be as carefully cherish'd in children, as other appetites suppress'd.
