All men by nature desire to know.

“All men by nature desire to know.”

Aristotle treats the desire for knowledge as a basic human tendency, giving curiosity a foundational place in the movement from perception toward understanding.

Source details

Aristotle, Metaphysics, Book I, Chapter I, W. D. Ross translation (1908), validated Wikisource scan leaf 21. 'All men by nature desire to know' opens the work before the discussion of sensation, memory, experience, art and knowledge. This remains ancient philosophy mediated by translation, not a modern empirical finding about cognition.

“Law is reason without desire.”

Good law is idealized as judgment governed by reason rather than by the changing appetites or personal passions of an individual ruler.

Source details

Politics: A Treatise on Government, Book III, Chapter XVI, William Ellis translation; represented through the 1912 Dent witness / Project Gutenberg #6762. In comparing rule by a person with rule by law, Aristotle says that passion can affect even the best rulers and concludes that law is reason without desire.

“You can control nothing but your own mind.”

Bennett redirects the desire to manage other people or circumstances toward the sphere he treats as directly governable: one’s own response and attention.

Source details

The Human Machine, discussion of mental control. The maxim belongs to Bennett’s period self-discipline philosophy and should not be read as a clinical claim that thoughts or symptoms are always voluntarily controllable.

It is a capital mistake to theorize before one has data.

“It is a capital mistake to theorize before one has data.”

Holmes argues that explanations should follow evidence because an early theory can tempt a person to force later facts into a preferred story.

Source details

“A Scandal in Bohemia,” The Adventures of Sherlock Holmes (1891), Project Gutenberg #1661. Holmes immediately warns that premature theorizing leads people to twist facts to suit theories; it is fictional detective dialogue.

Claude presents knowledge as difficult to obtain and live with, yet still capable of giving a kind of clarity or satisfaction once it is possessed.

Source details

Amours de Voyage, Letter X, “Claude to Eustace,—from Rome,” Project Gutenberg #1393. Claude’s two sentences about knowledge appear in the fictional verse-letter sequence after he turns from Roman politics toward study. This is Clough’s fictional epistolary voice, not direct autobiography or an empirical claim about happiness.

Source identified74
The world is my idea.

“The world is my idea.”

Faith, therefore, allows the greatest latitude in philosophic speculation, allowing us without blame to think what we like about anything.

“Faith, therefore, allows the greatest latitude in philosophic speculation, allowing us without blame to think what we like about anything.”

Spinoza separates faithful conduct from enforced uniformity of speculation: people can differ widely in philosophical belief while still being judged by whether their teaching leads toward justice and charity rather than hatred.

Source details

A Theologico-Political Treatise — Part III, Chapter XIV, paragraph 77, Project Gutenberg #991. The frozen catalog preserves the opening of Spinoza’s longer sentence; the paragraph continues by condemning teachings tending toward obstinacy, hatred, strife and anger and praising justice and charity. This is seventeenth-century theological / political philosophy, not a modern empirical claim.

Source identified76
The value of philosophy is, in fact, to be sought largely in its very uncertainty.

“The value of philosophy is, in fact, to be sought largely in its very uncertainty.”

Russell argues that uncertainty can be intellectually valuable because it loosens inherited assumptions and makes room for examined alternatives.

Source details

The Problems of Philosophy, Chapter XV, “The Value of Philosophy,” printed page 242 / scan leaf 246 in the 1912 Williams & Norgate edition on Wikisource, cross-checked against Project Gutenberg #5827. “The value of philosophy is, in fact, to be sought largely in its very uncertainty” begins Russell’s concluding account of how philosophical doubt can loosen unexamined certainty; this is philosophical argument, not an empirical psychological finding.

Source identified77
These questions enlarge our conception of what is possible, enrich our intellectual imagination and diminish the dogmatic assurance which closes the mind against speculation.

“These questions enlarge our conception of what is possible, enrich our intellectual imagination and diminish the dogmatic assurance which closes the mind against speculation.”

Questions matter even without final answers because sustained inquiry expands intellectual possibility and weakens premature certainty about what can be true.

Source details

The Problems of Philosophy, Chapter XV, “The Value of Philosophy,” closing paragraph, beginning on printed page 249 / scan leaf 253 in the fully validated 1912 Williams & Norgate Wikisource scan, cross-checked against Project Gutenberg #5827. “These questions enlarge our conception of what is possible...” explains why Russell values philosophical questions even when definite answers cannot usually be established; it remains an epistemological and educational-philosophical claim rather than a measured outcome guarantee.

The heart has its reasons, which reason knows not.

“The heart has its reasons, which reason knows not.”

Human judgment includes forms of intuition, feeling, and commitment that cannot always be reduced to explicit logical argument.

Source details

Diversity repels; likeness attracts.

“Diversity repels; likeness attracts.”

The concise axiom is one premise in Boethius’s metaphysical argument: things are described as tending toward what is like them, not as a modern empirical rule about human attraction or relationships.

Source details

How Substances Can Be Good in Virtue of Their Existence Without Being Absolute Goods (De Hebdomadibus), preliminary proposition IX, H. F. Stewart / E. K. Rand 1918 edition, Project Gutenberg #13316. Kept as a historical metaphysical premise, not social-science evidence.

All things, then, seek the good.

“All things, then, seek the good.”

Boethius frames action as movement toward some perceived good, making the nature of genuine goodness central to understanding desire, purpose, and happiness.

Source details

The Consolation of Philosophy, Book III, Chapter XI, H. R. James translation (Elliot Stock, 1897), printed page 149 in Project Gutenberg #14328. Lady Philosophy reaches ‘All things, then, seek the good’ after arguing that things naturally seek continued existence and unity, and that unity and goodness are the same. This remains late-antique metaphysical/philosophical argument mediated by translation, not an empirical description of every human motive or modern behavioral science.

Source identified81
I may be wrong.

“I may be wrong.”

The admission places a limit on Washington’s own policy claims and models intellectual uncertainty rather than presenting judgment as infallible.

Source details

The Future of the American Negro, Chapter VIII; Project Gutenberg #26507. The sentence appears in Washington’s closing policy discussion immediately after his summary of dangers and immediately before his qualification that he may also be in some degree right.

Source identified82

Voice: Fictional character · Mr. Jaggers

Appearances are weak evidence; better judgment comes from examining what can actually be supported.

Mr. Jaggers tells Pip “Take nothing on its looks; take everything on evidence. There’s no better rule” while insisting that he has stayed to the strict line of fact about Pip’s benefactor. Verified against the scan-backed Wikisource Volume III Chapter I transcription and cross-checked with Project Gutenberg #1400. This remains fictional legal dialogue and character method rather than a modern legal or scientific standard.

“Simplicity is a state of mind.”

Simplicity is defined first as an inward orientation rather than a particular income, occupation, costume or social class.

Learning without thought is labour lost; thought without learning is perilous.

“Learning without thought is labour lost; thought without learning is perilous.”

Study and reflection are treated as partners: information without examination is shallow, while speculation without learning can drift away from reality.

But nobody can account for the possession of fear when it takes hold of the mind.

“But nobody can account for the possession of fear when it takes hold of the mind.”

Defoe’s narrator observes how fear can persist and spread beyond what the immediate facts justify, especially during collective crisis and rumor.

Reason is, and ought only to be, the slave of the passions,

“Reason is, and ought only to be, the slave of the passions,”

Hume argues that reasoning can inform means and consequences but does not by itself supply the motivating ends that move a person to act.

Source details

A Treatise of Human Nature, Book II, Part III, Section III, “Of the Influencing Motives of the Will,” Project Gutenberg #4705. The frozen catalog retains the opening clause “Reason is, and ought only to be, the slave of the passions,” from a longer sentence. It remains Hume’s historical philosophical thesis rather than contemporary empirical psychology.

Source identified88
A wise man, therefore, proportions his belief to the evidence.

“A wise man, therefore, proportions his belief to the evidence.”

Hume argues that confidence should rise or fall with the strength and consistency of the available evidence rather than remain fixed regardless of what experience supports.

Source details

An Enquiry Concerning Human Understanding, Section X, ‘Of Miracles,’ Part I, paragraph 87 in the represented Selby-Bigge text, Project Gutenberg #9662. ‘A wise man, therefore, proportions his belief to the evidence’ follows Hume's discussion of varying degrees of assurance from experience. It is eighteenth-century epistemological argument and preserves the connective ‘therefore’; it is not a complete modern statistical or scientific decision rule.

Source identified89
Life is easy to chronicle, but bewildering to practice.

“Life is easy to chronicle, but bewildering to practice.”

Forster’s narrator contrasts the clarity of describing another person’s life from outside with the confusion of recognizing one’s own desires while actually living them.

Source details

A Room with a View, Chapter XIV, Project Gutenberg #2641. The frozen catalog wording is a clause extract from the narrator’s longer sentence: “Life is easy to chronicle, but bewildering to practice, and we welcome ‘nerves’ or any other shibboleth that will cloak our personal desire.” The passage concerns Lucy Honeychurch’s self-deception in fiction, not modern psychological evidence.

“It’s better by far to hunt for a star, than the spots on the sun abiding.”

Wilcox contrasts constructive attention with habitual fault-finding, recommending a perspective that actively looks for what remains promising without claiming flaws do not exist.

Poems of Cheer, “As You Go Through Life,” represented 1914 edition; Project Gutenberg #3238. The poem explicitly acknowledges that things go wrong, so the line is about chosen attention rather than denial.

Source identified91
But nature is a stranger yet; The ones that cite her most Have never passed her haunted house, Nor simplified her ghost.

“But nature is a stranger yet; The ones that cite her most Have never passed her haunted house, Nor simplified her ghost.”

Even close observers do not fully explain nature in this ending; familiarity with natural objects leaves room for strangeness, uncertainty and intellectual humility.

Source details

“A Well,” Poems: Third Series (1896), Project Gutenberg #12242. The ghost and haunted-house language is metaphorical, emphasizing nature's unresolved mystery.

“Certainly, it is heaven upon earth, to have a man's mind move in charity, rest in providence, and turn upon the poles of truth.”

Bacon joins truth with charity and steadiness, presenting intellectual honesty as part of a well-ordered mind rather than a weapon for pride.

Source details

Francis Bacon, 'Of Truth,' essay I in the 1625 Essays; independently checked against the validated 1884 Works of Francis Bacon, Volume I scan leaf 139. The retained sentence closes Bacon's theological/philosophical truth discussion by linking charity, providence and truth; it is explicitly early-modern Christian-philosophical rhetoric, not clinical or scientific evidence.

Partial knowledge is more triumphant than complete knowledge; it takes things to be simpler than they are.
