Definition

Conscience, in law, carries two distinct but related meanings depending on context.

1. EQUITY AND MORAL OBLIGATION: The internal moral faculty that courts of equity historically invoked as the foundation of their jurisdiction. Equity acted upon the conscience of a defendant — compelling performance, restraining wrongful conduct, or imposing constructive obligations — where strict common law rules would produce unjust results. In this sense, conscience is not merely an individual's subjective moral feeling but an objective legal standard: what a person of good faith and honest dealing ought to recognize as binding. A party who holds property obtained by fraud, undue influence, or breach of fiduciary duty holds it subject to a claim on their conscience, making equitable relief available.

2. CONSCIENTIOUS BELIEF OR SCRUPLE: A sincere, deeply held moral or religious conviction that compels or forbids a course of action. In this sense, conscience appears most prominently in constitutional and statutory law governing religious freedom, military conscientious objector claims, and exemptions from generally applicable legal requirements. This usage asks whether a belief is genuinely held and fundamental to the claimant's moral identity, not whether it is theologically orthodox or externally verifiable.

Common Language

Modern common usage (Wiktionary): The ethical or moral sense of right and wrong, chiefly as it affects a person's own behavior and forms their attitude to past actions.

Historical common usage (Webster's 1913): The faculty, power, or inward principle which decides as to the character of one's own actions, purposes, and affections, warning against and condemning that which is wrong, and approving and prompting to that which is right.

The gap between common and legal meaning is real but subtle. In common speech, conscience is purely subjective — a private, interior experience. In law, conscience functions as an external standard against which conduct is measured (equity) or as a legally cognizable category of belief that can trigger rights and exemptions (constitutional and statutory law). A researcher who reads equity sources expecting to find discussions of individual psychology will instead find a formalized doctrine: conscience is the hook on which equitable jurisdiction hangs, not a description of what any particular defendant actually felt.

Common Confusion

CONSCIENCE vs. PRINCIPLE: Black's Law Dictionary (1st Ed.) expressly distinguishes these terms, noting that an "objection on principle" is not equivalent to a "conscientious scruple." The distinction matters in historical sources governing exemptions and in equity pleading: a preference, opinion, or philosophical stance does not rise to a legal conscience claim. Researchers encountering these terms in nineteenth-century cases should not treat them as interchangeable.

CONSCIENCE (EQUITABLE) vs. CONSCIOUSNESS (PSYCHOLOGICAL): The archaic English sense of conscience as awareness or consciousness — flagged in Webster's 1913 as obsolete — occasionally surfaces in pre-nineteenth-century legal texts. The two concepts are distinct; equitable conscience is a normative standard, not a cognitive state.

Recognized Forms

/SUBTYPES

Courts of Conscience: Equity courts, and later small claims or local civil courts with equitable-style discretion, were historically called courts of conscience. The term signals a court authorized to depart from strict legal rules in favor of fair dealing. See Black's Law Dictionary definitions under CONSCIENCE, COURTS OF.

Conscientious Objection: The application of conscience in the sense of sincere moral or religious belief to resist a legal obligation — most classically, military service. This category has its own developed constitutional and statutory framework entirely separate from equity doctrine.

Why It Matters in Research

The dual life of this term creates a navigation problem across the Law Mind corpus. Equity sources from the seventeenth through nineteenth centuries use conscience as a term of art meaning the jurisdictional and moral foundation of equitable relief — it explains why a chancellor could intervene when a common law court could not. Researchers reading early treatises on trusts, fraud, or specific performance will encounter conscience used this way constantly, and misreading it as mere rhetorical flourish causes serious analytical errors.

The constitutional and statutory usage of conscience is almost entirely a twentieth-century development in American law. The two bodies of doctrine rarely cite each other, yet both appear in the Law Mind corpus under this single headword. A search for conscience in equity materials will surface different cases, different conceptual frameworks, and different remedies than a search in constitutional or religious liberty materials.

Trap for researchers in historical sources: Anderson's Dictionary notes that many cases against natural justice are "left wholly to the conscience of the party, and are without redress, equitable or legal." This is not a statement of modern law. It reflects the older understanding that equity could not reach every moral wrong — conscience as law's outer boundary, marking what lies beyond judicial cognizance. Do not read this as a general proposition that conscience claims are non-justiciable; that conclusion does not carry forward to modern First Amendment doctrine.

Jurisdictional variation in the equity sense is pronounced in the pre-merger era: states with separate equity courts treated conscience-based jurisdiction formally; states without equity courts absorbed the concept into merged civil procedure with varying degrees of fidelity to the original doctrine.

Historical Dictionary Support

The three source dictionaries converge on the moral-faculty definition but illuminate it differently. Anderson's Dictionary provides the clearest statement of the equitable limit: conscience marks the zone where law concedes to morality without providing a remedy, distinguishing perfect legal duties from imperfect moral ones. This is a foundational concept in the relationship between law and equity that later dictionaries compress or omit.

Black's (2nd Ed.) extends the definition beyond self-regarding morality to include applying moral standards to the conduct of others — a significant expansion that supports the use of conscience as an external legal standard, not merely a subjective one. This framing grounds the chancellor's power to examine a defendant's conduct against objective norms of probity and justice.

Black's (1st Ed.) is notable for what it does not do: rather than defining conscience substantively at length, it immediately draws the distinction from principle, signaling that the operative legal question in its era was the threshold between a cognizable conscience claim and a mere opinion. This reflects a period when conscientious scruple was litigated as a category — in juror exemptions, oath requirements, and early exemption claims — and courts needed a workable line.

What the historical dictionaries miss: none of them anticipates the constitutional dimension that dominates modern conscience doctrine. The First Amendment framework, selective service conscientious objector categories, and statutory conscience clauses in healthcare and other contexts are entirely post-dictionary developments requiring the researcher to move from these sources to constitutional and statutory materials.

Jurisdictional Note

In the equity sense, conscience as a term of art reflects the English Chancery tradition and was received into American law unevenly. States that merged law and equity early sometimes obscured the doctrinal heritage. In the constitutional sense, conscience claims are governed by federal First Amendment doctrine, but some states provide broader statutory or state constitutional protections — particularly in healthcare refusal and educational exemption contexts.

Anderson's Dictionary of Law • 1890

The moral sense; the sense of right and justice. There are many cases against natural justice which are left wholly to the conscience of the party, and are without redress, equitable or legal.4 Human laws are not so perfect as the dictates of conscience, and the sphere of morality is more enlarged than the limits of civil jurisdiction. There are many duties, belonging to the class called "imperfect obligations," which are binding on conscience, but which human laws do not and cannot undertake directly to enforce. But when the aid of a court of equity is sought to carry into execution such a contract, then the principles of ethics have a more extensive sway. See RIGHT, 1; FAITH. Conscionable. In accord with strict honesty and justice: as, a conscionable appraisement or inventory of the articles of a decedent's estate. Unconscionable. Contrary to probity, fair-dealing, or what a fair-minded man would do or refrain from doing: as, an unconscionable contract or bargain, q. υ. Conscionable is an ill-contrived word: from conscience-able, or conscible (not now in use).. 1 [2 Bl. Com. 203-4; 45 Pa. 432. 2 Bl.

Black's Law Dictionary (2nd Ed.) • 1910

The moral sense; the faculty of judging the moral qualities of actions, or of discriminating between right and wrong; particularly applied to one’s perception and Judgment of the moral qualities of his own conduct, but in a wider sense, de . CONSCIENCE noting a similar application of the standards of morality to the acts of others. In law, especially the moral rule which requires probity, justice, and honest dealing between man and man, as when we say that a bar gain is “against conscience” or “unconscionable,” or that the price paid for property at a forced sale was so inadequate as to “shock the conscience.” This is also the meaning of the term as applied to the jurisdiction and principles of decision of courts of chancery, aS in saying that such a court is a “court of conscience,” that it proceeds “according to conscience,” or that it has cognizance of “matters of conscience.” See 3 Bl. Comm. 47-56; People v. Stewart, 7 Cal. 143; Miller v. Miller, 187 Pa. 572, 41 Atl. 277. —Conscientious scruple. <A scruple against taking an oath, serving as a juror in a capital case, doing military duty, or the like, is an objection or repugnance growing out of the fact that the person believes the thing demanded of him to be morally wrong, his conscience being the sole guide to his decision; it is thus distinguished from an “objection on principle,” which is dictated by the reason and judgment, rather than the moral sense, and may relate only to the propriety or enpeuiency of the thing in question. People v. Stewart, 7 Cal. 143.—“Conscience of the court.” When an issue is sent out of chancery to be tried at law, to “inform the conscience of the court,” the meaning is that the court is to be supplied with exact and dependable information as to the unsettled or disputed questions of fact in the case, in order that it may proceed to decide it in accordance with the BP tag of equity and good conscience in the light of the facts thus determined. See Watt v. Starke, 101 U. S. 252, 25 L. Ed. 826.—Conscience, courts -of. Courts, not of record, constituted by act of parliament in the city of London, and other towns, for the recovery of small debts; otherwise and more commonly called “Courts of Requests.” 3 Steph. Comm. 451.—Conscience, ht of. As used in some constitutional provisions, this phrase is equivalent to religious liberty or freedom of conscience. Com. vy. Lesher, 17 Serg. & R. (Pa.) 155; State v. Cummings, 36 Mo. 263. Conscientia dicitur a con et scio, quasi scire cum Deo. 1 Coke, 100. Conscience is called from con and scio, to know, as it were, with God.
