Sources

Every figure and quotation on this site traces to the materials below. Statistics were checked against the originals in August 2026; where a number has since been revised, the original remains the cited source. Read the originals — an argument you cannot audit is just another letterhead.

Documents

Diogenes Laertius, Lives of Eminent Philosophers, Book VI (3rd c. CE). The life of Diogenes of Sinope, including the reply “I am a citizen of the world” (kosmopolitês), VI.63.

Baruch Spinoza, Letter to J. Louis Fabritius (1673). Declining the Heidelberg chair: “I do not know the limits, within which the freedom of my philosophical teaching would be confined…” Elwes translation, via the Internet Sacred Text Archive.

George Washington, Farewell Address (1796). The departing president’s warning “in the most solemn manner against the baneful effects of the spirit of party generally” — party spirit which “agitates the community with ill-founded jealousies and false alarms, kindles the animosity of one part against another.” Text via the Avalon Project, Yale Law School.

Ralph Waldo Emerson, Self-Reliance (1841). “Whoso would be a man, must be a nonconformist,” and “Nothing is at last sacred but the integrity of your own mind.” Via Project Gutenberg (Essays, First Series).

Walt Whitman, Song of Myself (1855/1892), §51. “Do I contradict myself? / Very well then I contradict myself, / (I am large, I contain multitudes.)” Via the Walt Whitman Archive.

Henrik Ibsen, An Enemy of the People (1882). Dr. Stockmann, the compact majority, and “the strongest man in the world is he who stands most alone” — with the play’s own warning about where standing alone can curdle. Via Project Gutenberg.

Simone Weil, On the Abolition of All Political Parties (written 1943; first published in La Table ronde, 1950; English translation by Simon Leys, NYRB Classics, 2013). The party as “a machine to generate collective passions,” designed “to exert collective pressure upon the minds of all its individual members,” whose “first objective and also the ultimate goal … is its own growth, without limit.”

Václav Havel, “The Power of the Powerless” (1978). The greengrocer, his sign, and its real message: “I am obedient and therefore I have the right to be left in peace.”

George Orwell, Notes on Nationalism (1945). Nationalism defined as “the habit of identifying oneself with a single nation or other unit, placing it beyond good and evil and recognising no other duty than that of advancing its interests” — with Orwell’s insistence that the unit need not be a nation at all. Via the Orwell Foundation.

Eric Hoffer, The True Believer: Thoughts on the Nature of Mass Movements (Harper & Brothers, 1951), §9. “The less justified a man is in claiming excellence for his own self, the more ready is he to claim all excellence for his nation, his religion, his race or his holy cause.”

Groucho Marx, Groucho and Me (Bernard Geis, 1959). The resignation telegram: “Please accept my resignation. I don’t want to belong to any club that will accept me as a member.” Wording per Marx’s own memoir, which leaves the club discreetly unnamed; tradition identifies it as the Friars Club, and earlier newspaper variants exist (Quote Investigator traces the history).

Ray Oldenburg, The Great Good Place (Paragon House, 1989). The sociology of “third places” — the cafés, taverns, and halls where community happens without enrollment. Behind the repair proposed in The Empty Lodge.

Robert D. Putnam, “Bowling Alone: America’s Declining Social Capital,” Journal of Democracy 6, no. 1 (1995), expanded as Bowling Alone (Simon & Schuster, 2000). Source of the civic-membership declines cited on the Evidence page. Putnam reads the decline as loss, not liberation — a reading this site engages rather than hides.

The laboratory

Solomon E. Asch, “Effects of Group Pressure Upon the Modification and Distortion of Judgments” (1951); “Opinions and Social Pressure,” Scientific American 193, no. 5 (1955). The line-judgment experiments: 32 percent of critical-trial answers conformed to a unanimous wrong majority; about 75 percent of subjects conformed at least once; a single truthful ally cut conformity to roughly 5 percent. Summary figures via SimplyPsychology’s review of the original studies.

Rod Bond & Peter B. Smith, “Culture and Conformity: A Meta-Analysis of Studies Using Asch’s Line Judgment Task,” Psychological Bulletin 119, no. 1 (1996). 133 Asch-type studies across 17 countries: the conformity pull is universal, stronger in collectivist cultures.

Henri Tajfel, “Experiments in Intergroup Discrimination,” Scientific American 223, no. 5 (1970). The minimal-group experiments: boys sorted by ostensible painting preference favored their arbitrary in-group and frequently preferred maximizing the difference between groups over maximizing their own group’s absolute gain.

Dan M. Kahan, Ellen Peters, Erica Cantrell Dawson & Paul Slovic, “Motivated Numeracy and Enlightened Self-Government,” Behavioural Public Policy 1 (2017). Identical data interpreted correctly as a skin-cream trial and tribally as a gun-control study; the most numerate partisans diverged most. SSRN working paper linked.

Cass R. Sunstein, “The Law of Group Polarization,” Journal of Political Philosophy 10, no. 2 (2002). Deliberation among the like-minded predictably moves the group toward a more extreme point than the members’ pre-deliberation median. (Linked text is the 1999 working-paper version; the published article is behind Wiley’s paywall.)

More in Common, The Perception Gap (2019). United States study: partisans imagine roughly twice as many “extreme” opponents as exist; the politically disengaged are about three times more accurate than the highly engaged; heavy news consumers are nearly three times more distorted; frequent political posters more distorted than the silent.

The ledgers

Gallup, “New High of 45% in U.S. Identify as Political Independents” (January 2026). 45 percent independent in 2025 — a record — against 27 percent for each party; trend series from 33 percent in 1988. Basis of the first chart.

Pew Research Center, “As Partisan Hostility Grows, Signs of Frustration With the Two-Party System” (2022). Very-unfavorable views of the opposing party: under 25 percent of each party in 1994; 62 percent of Republicans and 54 percent of Democrats by 2022. Majorities of each party call the other immoral and dishonest; 48 percent of independents say they often wish for more parties to choose from.

Ingrid van Biezen, Peter Mair & Thomas Poguntke, “Going, going, … gone? The decline of party membership in contemporary Europe,” European Journal of Political Research 51 (2012). Party membership averages 4.7 percent of European electorates; absolute membership nearly halved since 1980; UK, France, and Italy each lost 1–1.5 million members over three decades; declines of at least 25 percent in every established democracy. Summary at the LSE EUROPP blog.

Pew Research Center, “How the Global Religious Landscape Changed From 2010 to 2020” (2025). The religiously unaffiliated grew by 270 million to 1.9 billion — 24.2 percent of world population — driven principally by switching out of religion, against demographic headwinds.

Pew Research Center, Religious Landscape Study (2023–24). Religiously unaffiliated Americans: 29 percent, up from 23 percent (2014) and 16 percent (2007); Christians 62 percent, down from 78 percent (2007).

Gallup, “U.S. Church Membership Falls Below Majority for First Time” (2021). Formal congregation membership 47 percent in 2020 — below half for the first time since measurement began in 1937 — versus 70 percent as recently as 1999.

U.S. Bureau of Labor Statistics, “Union Members — 2025” (February 2026). Union membership rate 10.0 percent of wage and salary workers, versus 20.1 percent in 1983, the first year of comparable data.

Unite America Institute, “Not Invited to the Party Primary”. Fifteen U.S. states hold closed congressional and state primaries, excluding 15.7 million registered independents (17.6 million voters including minor parties); 22 states close their presidential contests, excluding 23.5 million independents. Figures restated at Unite America’s explainer.

Office of the U.S. Surgeon General, Our Epidemic of Loneliness and Isolation (2023). The advisory documenting that about half of American adults report measurable loneliness — the ledger behind this site’s references to a loneliness epidemic, and the sober half of The Empty Lodge.

For the twelve questions

The empirical references invoked in Twelve Questions, Answered in Grey:

National Academies of Sciences, Engineering, and Medicine, The Economic and Fiscal Consequences of Immigration (2016). The consensus review behind “aggregate gains and contested local wage effects.”

Shanshan Li, Meir Stampfer, David Williams & Tyler VanderWeele, “Religious Service Attendance and Mortality Among Women,” JAMA Internal Medicine 176, no. 6 (2016). Among the studies behind “congregational life correlating with longevity.”

Caitlin Hughes & Alex Stevens, “What Can We Learn From the Portuguese Decriminalization of Illicit Drugs?” British Journal of Criminology 50, no. 6 (2010). The standard scholarly assessment of Portugal’s 2001 reform; an accessible overview is at Transform.

A note on method: single studies wobble; this site therefore leans on findings that have been replicated (Asch, via 133 studies), meta-analyzed, or measured independently by unrelated institutions (the membership declines). Where an authority cited here disagrees with this site’s conclusions — Putnam most of all — the disagreement is stated in the text rather than trimmed from it.
