“He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit.”
Restraint in speech is presented as evidence of understanding rather than lack of confidence.
Proverbs 17:27 in the King James Version.
“He that answereth a matter before he heareth it, it is folly and shame unto him.”
Answering before listening mistakes speed for competence; understanding requires enough restraint to hear the matter before judging it.
Proverbs 18:13 in the King James Version.
“Hear counsel, and receive instruction, that thou mayest be wise in thy latter end.”
Listening to correction and counsel is presented as an investment whose value becomes clearer over the course of a life.
Proverbs 19:20, King James Version.
“A word fitly spoken is like apples of gold in pictures of silver.”
The right words gain value from timing and fit, not merely from sounding impressive in isolation.
Proverbs 25:11, King James Version.
“Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.”
Good relationships can improve judgment and character through challenge, conversation, and mutual influence.
Proverbs 27:17 in the King James Version; the proverb uses sharpening as an image for the way one person can strengthen or refine another.
“A fool uttereth all his mind: but a wise man keepeth it in till afterwards.”
Immediate expression is not always honesty or wisdom; restraint can protect judgment from being replaced by whatever emotion arrives first.
Proverbs 29:11 in the King James Version.
“Trust in the LORD with all thine heart, and lean not unto thine own understanding.”
Within Proverbs’ religious framework, trust is directed toward God rather than treated as unlimited confidence in one’s own judgment, pairing faith with humility about the limits of personal understanding.
King James Version, Proverbs 3:5. This is explicitly religious wisdom literature; this collection keeps its theological trust context visible instead of converting it into generic self-help advice.
“Our intellectual and active powers increase with our affection.”
Affection can call forth capacities that remain dormant in isolation; Emerson illustrates the claim with a writer who suddenly finds thoughts and words when writing to a friend.
Essays: First Series, “Friendship” (1841), verified against Project Gutenberg #2944 and the page-numbered 1907 Merrill/Turpin Essays witness in Project Gutenberg #16643, printed page 117. Emerson says “Our intellectual and active powers increase with our affection” before illustrating the claim with a scholar who finds thoughts and language when writing to a friend; it remains literary-philosophical observation rather than a quantified psychological law.
“There is then creative reading as well as creative writing.”
Reading can be an active intellectual act when the reader interprets, connects, questions, and produces new understanding rather than merely receiving words passively.
The American Scholar; Emerson argues that books should awaken independent thought rather than replace it.
“The optimist has the power of seeing things in their entirety and in their right relations.”
Optimism is defined here as a broader way of interpreting circumstances: the positive outlook is linked to seeing relationships and the whole situation rather than only one discouraging part.
In Tune with the Infinite, Prelude; Project Gutenberg #23559. The sentence belongs to Trine’s philosophical New Thought contrast between optimist and pessimist and should not be treated as a clinical definition.
“The present state of things is the consequence of the former.”
Understanding present conditions requires tracing the earlier choices and causes that produced them rather than treating the present as isolated.
Rasselas, Chapter XXX; Imlac argues that studying history helps people understand the sources of present benefits and harms.
“A sensible polite person does not assume to be better or wiser or richer than his neighbour.”
Smiles connects humility with ordinary social behavior: modest conduct resists turning differences in knowledge, wealth, rank or achievement into claims of personal superiority over other people.
Character, Chapter IX, “Manner—Art,” Project Gutenberg #2541. Smiles places the sentence in his discussion of politeness as respect for the personality and circumstances of others, then describes the well-mannered person as modest, unpretentious and more interested in doing than boasting.
“All useful and beautiful thoughts, in like manner, are the issue of labour, of study, of observation, of research, of diligent elaboration.”
Smiles describes developed ideas as products of study, observation, research and revision, making intellectual creativity a process of deliberate elaboration.
Thrift, Chapter I, “Industry,” Project Gutenberg #14418. Smiles applies the chapter’s labour argument to intellectual and creative production, listing study, observation, research and diligent elaboration as the work behind useful and beautiful thought.
“Regard him as loyal, and you will make him loyal.”
Seneca suggests that suspicion can become self-reinforcing: treating a chosen friend as trustworthy helps create the conditions for candid, reciprocal friendship rather than teaching defensiveness from the outset.
Moral Letters to Lucilius, Letter 3, Richard M. Gummere translation. Seneca immediately contrasts this with people who fear deception so strongly that their suspicions help teach others to deceive them.
“When friendship is settled, you must trust; before friendship is formed, you must pass judgment.”
Seneca separates two stages that are often confused: evaluate carefully before admitting someone into close friendship, then stop treating an accepted friend as though the relationship were still permanently on trial.
Moral Letters to Lucilius, Letter 3, “On True and False Friendship,” Richard M. Gummere translation.
“The fool who knows his foolishness, is wise at least so far. But a fool who thinks himself wise, he is called a fool indeed.”
The verse treats recognition of one’s own foolishness as the beginning of wisdom, while self-certainty without understanding becomes a deeper form of ignorance.
Dhammapada 63, Chapter V, “The Fool,” F. Max Müller translation, Project Gutenberg #2017. The verse belongs to a Buddhist canonical collection and remains a textual source voice rather than a modern individual-author quotation.
“The men with the muck-rakes are often indispensable to the well-being of society.”
Investigative criticism can serve society, Roosevelt argues, but its usefulness depends on truth, proportion and retaining the ability to distinguish genuine wrongdoing from indiscriminate condemnation.
The Man with the Muck-Rake, April 14, 1906. This sentence begins a qualification that such critics remain useful only if they know when to stop; the speech is not a blanket rejection of investigative journalism.
“When angry, count ten, before you speak; if very angry, an hundred.”
Jefferson’s practical rule inserts a deliberate delay between anger and speech, giving judgment time to return before emotion becomes an irreversible response.
Thomas Jefferson to Thomas Jefferson Smith, February 21, 1825, Founders Online / National Archives. The sentence is item 10 in a short list of “canons of conduct” sent to his namesake relative; the archive currently labels the transcription an Early Access document rather than a final authoritative edition.
“Time makes more converts than reason.”
Ideas that initially provoke resistance can become easier to accept as experience changes what people consider normal or possible.
Common Sense (1776), Introduction. The represented wording is verified in Project Gutenberg #147 and the validated scan-backed Wikisource 1776 sixth-edition transcription; Paine follows his warning that custom can make an error look right by observing that time often changes opinion where argument initially does not.
“The ideal of human brotherhood has become a practical possibility.”
Human solidarity is treated not merely as abstract sentiment but as an achievable political and social aim requiring organized effort and mutual recognition.
The Conservation of Races, closing programmatic resolutions. The sentence belongs to Du Bois’s 1897 argument about race organization and human brotherhood; period racial concepts remain historical context rather than modern science.
“You shall listen to all sides and filter them from yourself.”
Whitman urges the reader not to borrow even his own viewpoint wholesale: other voices can be heard, but judgment still has to be worked through personally rather than accepted second-hand.
Leaves of Grass (1855), untitled first-edition poem later known as “Song of Myself,” printed page 14 (Wikisource scan page 20). The sentence follows Whitman’s warning against taking things at second or third hand and against looking only through another person’s eyes; the reviewed locator is edition-specific.
“all progress of mind consists for the most part in differentiation, in the resolution of an obscure and complex object into its component aspects”
Pater describes intellectual progress as learning to distinguish parts within what initially seems confused, a method that makes clearer categories and more exact judgment possible.
Appreciations, with an Essay on Style, essay “Style,” printed page 5 in the standard Macmillan 1910 Library Edition pagination reproduced by Project Gutenberg #4037. “all progress of mind consists for the most part in differentiation...” opens Pater’s argument by distinguishing prose, verse and poetry. This is literary-aesthetic criticism, not a modern experimental claim about cognition or learning.
“He will remember always that beauty exists in many forms.”
The sentence resists a single narrow standard of beauty and asks the critic to remain open to excellence appearing through different periods, types and schools.
The Renaissance, Preface; Project Gutenberg #2398. The following sentences extend the point across periods and schools of taste.
“The service of philosophy, of speculative culture, towards the human spirit is to rouse, to startle it into sharp and eager observation.”
Pater values philosophy for sharpening attention: its practical intellectual service is to make perception more alert rather than allowing experience to pass unnoticed through habit.
The Renaissance, Conclusion; Project Gutenberg #2398. The line belongs to Pater’s historically controversial conclusion on experience and culture.
“the first step towards seeing one's object as it really is, is to know one's own impression as it really is, to discriminate it, to realise it distinctly.”
Critical judgment begins with accurately noticing one’s own response before turning that response into a claim about the work, making self-observation part of disciplined interpretation.
The Renaissance, Preface; Project Gutenberg #2398. Pater is describing aesthetic criticism, not claiming that personal impression alone settles every factual question.
“The best men are not consistent in good—why should the worst men be consistent in evil?”
Walter Hartright rejects a simple moral picture in which people behave with perfect consistency, allowing that even deeply flawed characters can act in mixed or unexpected ways.
The Woman in White, Third Epoch, ‘The Story Continued by Walter Hartright,’ section II, Project Gutenberg #583. Walter tells Marian ‘The best men are not consistent in good—why should the worst men be consistent in evil?’ while they assess Count Fosco after Marian reports his warning. It remains fictional moral reasoning about a particular antagonist rather than an empirical rule about human behavior.
“There is a vital difference between error and untruthfulness.”
Being mistaken is separated from intentional falsehood, which allows honest uncertainty and correction without confusing every factual error with deceit.
The Power of Truth, opening chapter, Project Gutenberg #56020; Jordan distinguishes sincere error from deliberate untruthfulness.
“Theories thus become instruments, not answers to enigmas, in which we can rest.”
James describes theories as tools for moving inquiry and experience forward rather than final intellectual resting places that eliminate the need for further testing or revision.
Pragmatism, Lecture II, “What Pragmatism Means”; Project Gutenberg #5116. Capitalization has been normalized from the represented all-caps sentence while the wording is otherwise preserved.
“Our errors are surely not such awfully solemn things.”
James resists treating every possible intellectual mistake as catastrophic, because an excessive fear of error can itself prevent inquiry, experience and the possibility of gaining truth.
The Will to Believe, essay “The Will to Believe”; Project Gutenberg #26659. James is contrasting the risk of being mistaken with the cost of refusing every uncertain intellectual venture.
“The fool doth think he is wise, but the wise man knows himself to be a fool.”
Recognizing the limits of one’s knowledge is presented as a mark of wisdom, while certainty about one’s own wisdom can be evidence of the opposite.
As You Like It, Act V, Scene 1, Touchstone; 1919 Yale Shakespeare edition edited by Jack R. Crawford, printed page 89 / Wikisource scan leaf 101. Touchstone says, “The fool doth think he is wise, but the wise man knows himself to be a fool,” while verbally outmaneuvering William in a comic exchange over Audrey. The maxim remains fictional comic dialogue rather than a direct Shakespearean self-help proposition.
“Give every man thy ear, but few thy voice.”
Listening broadly while speaking selectively is presented as a practical discipline for judgment, relationships, and self-control.
Act 1, Scene 3; Polonius advises Laertes before his departure.
“There is nothing either good or bad, but thinking makes it so.”
The line separates events from the judgments people place on them, a useful distinction for thinking about perception and response.
Hamlet, Act 2, Scene 2; Hamlet says this to Rosencrantz and Guildenstern while explaining that Denmark feels like a prison to him. The line is dramatic dialogue, not a detached psychological proposition by Shakespeare.
“All that glisters is not gold.”
Appearance can imitate value without possessing it, so the line encourages evidence and discernment before admiration or trust.
Act 2, Scene 7; the inscription warns against judging by outward appearance.
“The devil can cite Scripture for his purpose.”
Even respected language can be quoted selectively, so a citation should be judged by context and purpose rather than authority alone.
The Merchant of Venice, Act 1, Scene 3.
“One touch of nature makes the whole world kin.”
Shared human tendencies can connect people across status and difference, even when the behavior being shared is imperfect.
Troilus and Cressida, Act III, Scene 3, Project Gutenberg #1528; Ulysses speaks to Achilles. ‘One touch of nature makes the whole world kin’ is immediately defined by the following lines: people ‘with one consent praise new-born gauds’ and the present eye praises the present object. The retained line therefore belongs to Ulysses’s argument about novelty, reputation and forgotten past merit, not an uncomplicated statement of sentimental universal fellowship or Shakespearean autobiography.
“Use the active voice.”
The rule favors direct sentence construction when it makes agency clearer, while the surrounding discussion still allows passive voice when context requires it.
The Elements of Style, Chapter III, Rule 10, Project Gutenberg #37134; Strunk immediately qualifies the rule by noting legitimate uses of passive construction.
“Put statements in positive form.”
Strunk recommends stating what is true or intended directly when possible instead of making the reader reconstruct the point from repeated negation.
The Elements of Style, Chapter III, Rule 11, Project Gutenberg #37134; the rule concerns sentence construction, not positive-thinking philosophy.
“Make the paragraph the unit of composition: one paragraph to each topic.”
Paragraphing is treated as an organizational decision: grouping one developed topic at a time helps readers follow the structure and movement of an argument.
The Elements of Style, Chapter III, Rule 8, Project Gutenberg #37134; the book discusses exceptions for very short subjects and rapid narrative.
