The Penny Knights: Civic Oaths as Working Infrastructure
Every enduring civic institution in the Anglo-American tradition has, at its core, an act of speech: a promise, made publicly, that binds the person who makes it to an obligation. The physician's Hippocratic oath, the knight's promise of fealty and protection, the US constitutional officer's oath "to support this Constitution," the military enlistment oath, the oath of naturalization — these are not ceremonial flourishes. They are the pre-legal mechanism by which a person transforms themselves, in public and on the record, from someone who happens to be doing a role into someone who is committed to that role's obligations.
The Penny Knights is a civic practice designed to bring that mechanism — the oath — into the daily life of ordinary Americans who want to take civic responsibility seriously but are not office-holders, service members, or naturalized citizens at a ceremony. The program has three chapters: Shiny (Justice), Rusty (Bravery), and PennyWell (Protection). Each chapter articulates a commitment. The penny is a deliberate choice of token: the smallest coin in the US currency, carried by almost everyone, and overlooked by almost everyone. A commitment worth its weight in pennies is also, if taken seriously, worth a great deal more than that. This is a chapter of the LongHouse Civic Library because the program makes no sense without the traditions it descends from.
Why oaths are civic infrastructure
The scholarly literature on oaths treats them as speech acts in the sense J. L. Austin described in How to Do Things with Words: utterances that, correctly made in the right context, bring about the state of affairs they describe. An oath is not a report about an already-existing commitment; it is the act that creates the commitment. This is why the US constitutional officer's oath (Article VI, Clause 3) matters: before the oath, a person elected or appointed to federal office is a person with a title. After the oath, they are "bound by oath or affirmation to support this Constitution." The binding is the oath itself.
Thomas Hobbes and John Locke, writing a century apart in the seventeenth century, both grounded their accounts of legitimate political authority on covenants — oaths of a sort — that members of a political community make with one another and with their government. Neither writer thought the formal oath was strictly necessary for political obligation; both thought that describing the obligation as if it were sworn made it intelligible in a way other framings did not. American civic practice has largely followed that intuition. The officers who take the oath are taken to be specifically bound; the rest of us are generally bound, in a way that invites specification whenever someone wants to make their commitment concrete.
That is what the Penny Knights do. They invite a person who is not otherwise required to swear anything to specify their civic commitment in the same grammar the law uses.
The oath traditions the Penny Knights draw on
The Hippocratic oath (c. 400 BCE)
The oldest continuously influential professional oath in the Western tradition. Attributed to the Greek physician Hippocrates, its surviving Greek text opens with a declaration of witnesses ("I swear by Apollo the healer, by Asclepius...") and proceeds to a series of specific prohibitions and positive commitments: not to administer a fatal drug, not to perform abortions, to teach the art freely to those who are bound by oath to it. The Hippocratic oath is important because it is specific — it lists acts the physician will and will not do — and because it is made to other physicians, not to a government. The oath-taker joins a community of practice that polices itself.
Modern medical schools generally administer a modernized form of the oath (the Declaration of Geneva is one such revision, adopted by the World Medical Association in 1948). Secondary scholarship on the text is extensive; the Library of Congress and most university classics libraries carry the Loeb Classical Library edition with parallel Greek–English text, which is the standard citation.
The knight's oath (12th–15th c.)
European chivalric orders codified a knight's commitments in formal oaths that varied by order and period but shared a consistent structure: fealty to a lord, defense of the Christian faith, protection of the weak (women, orphans, pilgrims, the poor), honesty, courage in battle, refusal of unworthy gain. The best-known surviving example is the oath of the Order of the Temple, though the tradition is represented in many orders from the Teutonic Knights to the Order of Santiago. The Rule of Saint Benedict (6th c.), technically a monastic rather than a knightly oath, supplied the formal vocabulary of vow-taking that later orders adopted.
The knight's oath is important for the Penny Knights because it articulates the commitment to protection of the weak as a positive duty rather than a voluntary charity. The knight is not someone who happens to protect the weak; the knight is someone who has sworn to do so, and has been publicly accepted into a community that enforces the commitment.
The US constitutional officer oath (1787)
Article VI, Clause 3 of the US Constitution: "The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution." Article II, Section 1, Clause 8 specifies the Presidential oath in its exact form: "I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."
Two features of the constitutional oath are worth noting. First, the option of "affirmation" rather than "oath" was a deliberate accommodation to religious communities (notably Quakers) whose traditions prohibited sworn oaths. The Framers treated the substantive commitment as central; the religious form as negotiable. Second, the oath's object is the Constitution itself, not any office-holder or government. The officer swears loyalty to a document — which is to say, to a set of rules that binds the officer and the rest of the government alike.
The military enlistment oath (10 U.S.C. § 502)
The oath of enlistment has descended, with revisions, from the First Continental Congress's 1775 oath for the Continental Army. Its current form: "I, _____, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God." The officer's oath (10 U.S.C. § 3331) is identical except for the final clause about obedience to orders, which does not appear in the officer version.
Notice the ordering: support and defend the Constitution first; allegiance to the Constitution second; obedience to orders third, and only "according to regulations and the Uniform Code of Military Justice." This structure is not accidental. The enlistment oath is drafted to make clear that an unlawful order from a superior is not within the scope of the enlisted soldier's commitment.
The oath of allegiance for naturalization (8 U.S.C. § 1448)
Taken by every person admitted to US citizenship at the end of the naturalization process: "I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same..." Ten more clauses follow, covering the specific obligations of citizenship.
The naturalization oath is interesting for the Penny Knights because every other oath in this list is taken by someone who has accepted a specific role (physician, knight, officer, enlisted service member). The naturalization oath is taken by someone who is accepting the general role of citizen. Native-born Americans never take it. One of the small injustices of American civic life is that a large share of the country has never sworn the oath its immigrant neighbors have had to swear.
The three Penny Knights chapters
Shiny — Justice
The Shiny chapter articulates a commitment to the rule of law as a personal practice. Its vocabulary draws on the constitutional officer oath: the Penny Knight commits to support the Constitution in the concrete sense of not taking actions, in private or public life, that substitute personal preference for due process when due process applies. The source of the language is Magna Carta clause 39, as transmitted through Coke's Institutes, the 1689 Bill of Rights, and the Fifth and Fourteenth Amendments (see the Magna Carta primer for the transmission arc). The practical content of the commitment: before taking an action that affects another person's rights or standing, ask whether the process you are using is one that person would recognize as fair.
Rusty — Bravery
Bravery in the Penny Knights sense is civic, not martial. The vocabulary comes closer to Aristotle's Nicomachean Ethics Book II than to any military tradition: courage is a virtue (a settled disposition) located between the vices of cowardice and recklessness. Chester Barnard, the early-twentieth-century organizational theorist, articulated a useful modern version in The Functions of the Executive (1938): organizational courage is the willingness to make a correct decision that will cost you personally, when the cost of the correct decision is predictable in advance. The Rusty chapter commits the Penny Knight to that form of courage in civic settings — speaking accurately at a public meeting when it would be easier to stay silent, declining to sign a petition whose contents the Penny Knight has not read, reporting a procedural irregularity at a polling place.
PennyWell — Protection
Protection, in the Penny Knights sense, is care-taking as a civic practice. The vocabulary draws on the chivalric tradition's commitment to protecting the weak, but without the martial framing that tradition accumulated. Mahatma Gandhi's account of satyagraha (soul-force) in his 1908 Hind Swaraj articulates a form of protection that is neither violent nor passive: the protector interposes their presence between a stronger party and a weaker one without returning harm for harm. The PennyWell chapter commits the Penny Knight to that form of protection — not as dramatic intervention but as the daily practice of noticing who in a civic setting is being overlooked, undervoiced, or procedurally disadvantaged, and doing what is within the Penny Knight's capacity to correct the asymmetry.
The penny motif
Why a penny. The penny is the smallest denomination in US currency. Its face value is below the cost of producing it; by most economic measures it should have been retired decades ago. It persists because it is useful as a marker for things that are small individually but accumulate: the tip jar, the wishing-well fountain, the coin in the shoe on a wedding day. A commitment represented by a penny is a commitment worth paying attention to precisely because it is easy to lose track of. The Penny Knight carries the penny not as magical protection but as a daily reminder: when the coin comes to hand — in a pocket, on a sidewalk, in a tip jar — the reminder is there.
There is a second, more specific reason. The US penny (technically, the one-cent coin) features Abraham Lincoln on the obverse, designed by Victor David Brenner in 1909. Lincoln was an office-holder who took the constitutional officer oath on March 4, 1861, at the outset of the only war fought on American soil in which the federal government fought to preserve, not dismantle, constitutional continuity. The penny carries his image; the Penny Knight carries the penny; the chain of commitment is specific, not vague.
How this fits the civic library
The primers and case briefs in this library answer the question What does the law say? They document how constitutional doctrine arrived at its current state, what the landmark cases held, and how the traditions of due process and equal protection work in practice. The Penny Knights answer a complementary question: What do I personally commit to, in light of what the law says? The first question is academic. The second is operational. The library is complete only when both are present.
The three Penny Knights chapters (Shiny, Rusty, PennyWell) each correspond to one of the constitutional virtues the other library chapters document. Shiny corresponds to the due-process tradition running from Magna Carta through Marbury and Miranda. Rusty corresponds to the courage required to apply that tradition in the face of cost — Cooper v. Aaron (1958) is the canonical case study; the Penny Knight equivalent is civic rather than judicial. PennyWell corresponds to the equal-protection tradition running through Brown v. Board and its civil-rights successors. Taking a Penny Knights oath without reading the primers is empty; reading the primers without making a personal commitment is incomplete.
