The sentence is witty fictional dialogue inside Trollope's satire, not a factual rule about love or happiness.

Aristotle, Metaphysics, Book I, Chapter I, W. D. Ross translation (1908), validated Wikisource scan leaf 21.

The Hound of the Baskervilles, Chapter III, “The Problem,” Project Gutenberg #2852. Sherlock Holmes says that the world is full of obvious things nobody observes after inferring from Watson’s clean clothes and boots that he spent the rainy day indoors, then asks Watson to infer where Holmes himself has been.

Volpone, Act I, Scene 1, Project Gutenberg #4039. Volpone opens the comedy by greeting his gold as a saint while Mosca reveals the hoard; the religious imagery establishes his avarice. It is fictional dramatic speech, not Ben Jonson autobiography, financial advice or a literal religious claim.

Elwes translation represented by Project Gutenberg #3800. ‘Blessedness is not the reward of virtue, but virtue itself’ introduces Spinoza's proposition linking blessedness, knowledge, virtue and control of the emotions. It remains translation-mediated seventeenth-century metaphysical ethics, not a universal psychological measurement or clinical prescription.

Spinoza says the terms good and evil are applied relatively while introducing his distinction between ordinary relative goods and the true/highest good sought by the unfinished treatise. It remains translation-mediated seventeenth-century methodological philosophy rather than a claim that all moral distinctions are meaningless.

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.

The Consolation of Philosophy, Book II, Chapter IV, H. R. James translation (Elliot Stock, 1897), printed page 60 in Project Gutenberg #14328. The retained catalog wording ‘Nothing is wretched, but thinking makes it so.’ is a frozen clause extract from James’s longer sentence beginning ‘So true is it that...’ in Lady Philosophy’s argument about Fortune, judgment and the instability of external circumstances.

On the Origin of Species, closing paragraph, first-edition wording represented by Project Gutenberg #1228. Later editions inserted “by the Creator” into this sentence; this record deliberately follows the 1859 form and keeps the quotation inside Darwin’s scientific argument about descent with modification.

The Descent of Man, and Selection in Relation to Sex, Introduction, represented by Project Gutenberg #2300. Darwin writes that 'ignorance more frequently begets confidence than does knowledge' while rejecting confident claims that human origins could never be solved by science. The frozen quotation capitalizes the clause as a standalone sentence although it appears after a colon in the witness; it remains a historical scientific argument, not a universal quantitative law about confidence.

Journal of Researches / The Voyage of the Beagle, concluding chapter, represented by the public-domain Project Gutenberg work. Darwin continues by describing novelty, comparison and self-reliance as benefits of travel; the recommendation reflects nineteenth-century natural-history practice and its historical colonial setting.

Great Expectations (1861), global Chapter XL / Volume III Chapter I in the Chapman & Hall three-volume first book edition. 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.

Martin Chuzzlewit, Chapter X, Project Gutenberg #968. Old Martin Chuzzlewit says that regrets are the natural property of grey hairs while speaking to Pecksniff during a deliberately strategic performance. The maxim remains fictional character speech shaped by manipulation and family conflict rather than direct Dickens autobiography or a clinical claim about aging.

The Pickwick Papers, near the closing chapter, Project Gutenberg #580. The narrator deliberately leaves Pickwick and his companions in a moment of happiness and contrasts life’s “dark shadows” with its stronger lights; this is literary narration, not a promise that suffering always ends well.

Hypatia — or New Foes with an Old Face, Chapter XXIV, “Lost Lambs,” Project Gutenberg #6308. Pelagia tells Philammon that men love women for their own sakes while women love “for love’s sake” during a distressed reflection on betrayal, dependence and the absent Amal. It is fictional dialogue in Kingsley’s historical novel, not a universal claim about men and women.

The Water-Babies, represented by Project Gutenberg #1018. Tom recalls the mysterious Irishwoman’s warning while half asleep. The cleanliness language participates in Kingsley’s Victorian Christian moral fantasy and is not a scientific claim about character or hygiene.

Herland, Chapter 12, “Expelled,” Project Gutenberg #32. Van Jennings narrates that after more than a year in Herland the visitors have become accustomed to seeing women “not as females but as people” across every kind of work. This is retrospective fictional narration inside Gilman’s feminist utopian novel, not a neutral sociological finding.

The Yellow Wallpaper, represented by Project Gutenberg #1952. The words are spoken by the unnamed narrator to John at the story’s disturbing climax; the scene depicts psychological breakdown inside fiction and is not presented as mental-health guidance.

Women and Economics, Chapter VIII, Project Gutenberg #57913. Gilman rejects the contemptuous category of a “female mind,” immediately adding that the brain is not an organ of sex and comparing “female mind” to “female liver.” It is a historical equality argument embedded in Gilman’s period-specific social/evolutionary framework, not a current neuroscience citation.

The Tragical History of Doctor Faustus, represented by Project Gutenberg #779. Faustus speaks to a supernatural apparition of Helen late in the tragedy; the line is fictional dramatic speech in a scene of temptation and damnation, not Marlowe’s autobiographical judgment.

Hero and Leander, posthumously published in 1598. The sentence is a narrator’s rhetorical claim inside mythological narrative poetry and should not be treated as psychological evidence about how real relationships develop.

Analects 2:15 in James Legge’s translation; the saying balances study with independent reflection.

The Analects of Confucius, Book VII, Chapter XXXVI, James Legge translation, Project Gutenberg #3330.

A Journal of the Plague Year, Project Gutenberg #376. The remark follows a false rumor that meat in Newgate Market was infected. It is historical-literary plague narration, not modern psychological or medical guidance.

Robinson Crusoe, represented by Project Gutenberg #38705. Crusoe says this while reflecting on what he interprets as secret intimations of Providence; the sentence is fictional first-person religious reflection, not evidence for supernatural guidance.

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.

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.

“Of the Standard of Taste,” first published in 1757 and represented by Fordham’s Modern History Sourcebook transcription. Hume subsequently qualifies this apparent subjectivism by discussing practiced judgment and durable critical standards, so the sentence is not the whole essay’s conclusion.

John Halifax, Gentleman, represented by Project Gutenberg #2351. The phrase belongs to the first-person narrator Phineas Fletcher while describing the river; it is a literary simile inside the novel, not direct autobiography by Craik.

Olive: A Novel, Chapter XI, Project Gutenberg #22121. Olive Rothesay tells Sara that if she loves Charles she should tell him so and give him her ‘whole life-long faith and affection’ while responding to Sara's first love-letter. This is fictional character counsel inside a nineteenth-century courtship plot rather than Craik autobiography or universally applicable relationship advice.

A Passage to India, Project Gutenberg #61221. The narrator explains Mrs. Moore’s more patient response to disappointment after an outing fails to materialize on cue; the sentence belongs to fictional narration.

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.

Howards End, Chapter XXII, Project Gutenberg #2946. The narrator summarizes Margaret’s hope of reconciling “the prose and the passion” in Henry with “Only connect! That was the whole of her sermon.” The sentence belongs to the novel’s thematic and character context rather than serving as a complete formula for every relationship.

Five Children and It, Chapter I, “Beautiful as the Day,” Project Gutenberg #17314. The narrator observes how quickly the children become accustomed to the astonishing after they begin conversing with the Psammead. This is playful children’s-fantasy narration rather than an empirical psychological claim about adaptation.
