mauvaise foi
The phrase “mauvaise foi” is French: “mauvaise” from Old French “mauveis/malveis,” from Latin “malus” (bad, evil); “foi” from Old French “fei/foi,” from Latin “fides” (faith, trust, fidelity, reliability, good faith). In legal, theological, and everyday French, “bonne foi” (good faith) and “mauvaise foi” form an evaluative pair, originally tied to honesty, contractual reliability, and sincerity. Existentialist philosophers (especially Jean-Paul Sartre) resemanticized “mauvaise foi” into a technical term describing a particular, structurally complex mode of self-deception about one’s own freedom and responsibility.

- Latin “fides” (faith, trust, pledge); French “foi” (faith, belief), “bonne foi” (good faith, honesty), “mauvaise foi” (dishonesty, tendentious interpretation), “fidélité” (faithfulness), “confiance” (trust), “sincérité” (sincerity); English legal and moral terms such as “good faith,” “bad faith,” “honesty,” “integrity,” “deceit,” and theological “faith/unbelief.” The existentialist sense also overlaps with “self-deception,” “inauthenticity,” “denial,” “disavowal,” “double-mindedness,” and “evasion of responsibility.”
Rendering “mauvaise foi” simply as “bad faith” risks importing theological or legal connotations (lack of belief in God; acting dishonestly in a contract) that are too narrow, moralistic, or external. Sartrean bad faith is an internal, phenomenological structure of consciousness: one simultaneously knows and does not know what one is, and flees one’s own freedom through self-interpretation, not merely through lying to others or insincerity in the ordinary sense. Many languages have a ready equivalent for legal ‘bad faith’ but lack a compact phrase capturing self-deception about one’s existential freedom that is neither simple hypocrisy nor straightforward error. Translators must also navigate whether to retain the French phrase to signal its technical status, and how to convey that for Sartre it is not a stable character flaw but a dynamic project of avoiding anguish, with both cognitive and affective dimensions.
Before its philosophical crystallization, ‘mauvaise foi’ in French referred primarily to dishonesty, bad intent, or lack of sincerity in social and legal contexts, contrasted with ‘bonne foi’ (good faith). In medieval and early modern law and theology, cognates of Latin ‘mala fides’ and ‘fides’ were used to distinguish those who acted honorably and sincerely in contracts, oaths, and promises from those who intended deceit or acted with hidden reservations. In everyday speech, accusing someone of ‘mauvaise foi’ meant that they were arguing tendentiously, interpreting facts in a deliberately unfair way, or pretending not to understand in order to win a dispute—focused on interpersonal dishonesty rather than the inner, structural self-deception central to later existentialist usage.
The term acquires its technical, existential-phenomenological meaning with Jean-Paul Sartre, especially in *L’Être et le néant* (1943). Sartre reinterprets ‘mauvaise foi’ as a fundamental project of self-deception by which consciousness attempts to escape the anguish and responsibility that come with its ontological freedom. Classic illustrations—the café waiter who exaggerates his role to be ‘nothing but’ a waiter, the woman on a date who leaves her hand in a man’s without acknowledging the situation, or the homosexual who denies his homosexuality by appealing to pure facts or pure intentions—show bad faith as a flight from the ambiguity of human reality, which is simultaneously facticity (what one is, given circumstances) and transcendence (the freedom to surpass these conditions. Sartre’s account shifts the focus from moralistic labels of dishonesty to a structural, non-psychologistic analysis of consciousness, arguing that bad faith is pervasive and, in some sense, a nearly inescapable temptation of human existence.
In contemporary philosophy, ‘bad faith’ is used both narrowly, to mean Sartrean mauvaise foi, and more broadly, to denote various forms of culpable self-deception, ideological blindness, and motivated denial in moral, political, and social life. Feminist theorists (e.g., de Beauvoir, later second-wave feminists) analyze bad faith as complicity in patriarchy, where individuals internalize and reproduce oppressive norms while disavowing their agency. Critical race theorists use ‘racial bad faith’ to describe how dominant groups maintain self-images of fairness while ignoring or rationalizing systemic injustice. In analytic moral psychology, the notion informs debates on self-deception, weakness of will, and moral responsibility, though some prefer more neutral terms. Outside academic philosophy, ‘bad faith’ has entered public discourse—journalism, activism, online debate—to label disingenuous argumentation or rhetorical strategies that pretend openness or fairness while actually pursuing a hidden agenda, somewhat reverting to the pre-philosophical sense but with a lingering connotation of self-deception about one’s motives and commitments.
1. Introduction
Mauvaise foi (“bad faith”) is a philosophical term most closely associated with 20th‑century existentialism, especially the work of Jean‑Paul Sartre and Simone de Beauvoir. In this context it names a distinctive mode of self-deception or evasion of freedom, rather than simple dishonesty or lying to others. The concept has since been taken up and reworked in ethics, feminist theory, critical race theory, and analytic moral psychology.
At its core, mauvaise foi addresses a recurring tension in human life: people appear both aware of their capacity to choose and reshape their lives and yet often speak and act as though their identities, values, or social roles were fixed, dictated, or inevitable. Philosophers use “bad faith” to describe this complex stance of knowing and not knowing one’s own freedom and responsibility.
Historically, the expression derives from legal and moral contrasts between “good faith” and “bad faith” conduct in Latin and French traditions. Existentialist usage transforms this everyday and juridical vocabulary into a technical notion within a phenomenology of consciousness. Later thinkers extend it to phenomena such as ideological blindness, complicity in oppression, and disingenuous public rhetoric.
Because of its dual life as both a technical term and a common expression, “bad faith” sits at the intersection of several debates:
- how language about faith, trust, and honesty migrated from theology and law into existential philosophy;
- how freedom, facticity, and responsibility are understood in different philosophical systems;
- how patterns of denial and self-justification operate in individuals and groups.
The sections that follow trace the term’s linguistic and historical development, outline major philosophical treatments from Sartre and his influences to contemporary theorists, and map its connections to related notions such as authenticity, ideology, and inauthenticity.
2. Etymology and Linguistic Origins
2.1 Latin Roots: Fides, Bona fides, Mala fides
The genealogy of mauvaise foi begins with the Latin fides, meaning faith, trust, reliability, loyalty, and creditworthiness. From this noun, Roman legal and moral discourse developed the contrast between bona fides (good faith) and mala fides (bad faith).
“In omnibus obligationibus… id sequimur quod in bona fide gestum est.”
— Digest of Justinian, Digesta 50.17.145
Here “good faith” refers to honest intention in contracts and dealings; “bad faith” denotes deceptive or opportunistic behavior. These Latin expressions underwrite later Romance-language terms in law and ordinary speech.
2.2 Old French and Classical French: Foi and Mauvaise foi
In Old French, fei/foi inherits the semantic range of fides: religious belief (“faith”), personal trust, and contractual reliability. The adjective mauveis/malveis (from Latin malus, bad) yields mauvaise foi, literally “bad faith.”
By the early modern period, bonne foi and mauvaise foi are established as a pair in legal and literary French:
| Expression | Core Sense (Pre-philosophical) |
|---|---|
| bonne foi | honesty, candor, fair dealing, sincerity |
| mauvaise foi | dishonesty, tendentiousness, unfair argument |
The phrase is applied to litigants, witnesses, negotiators, and sometimes to disputants who argue in a deliberately one‑sided way.
2.3 Path into Modern Philosophical Vocabulary
In 19th‑ and early 20th‑century French, mauvaise foi continues to be used in moral, legal, and everyday contexts without a systematic philosophical definition. It denotes an agent’s interpretive dishonesty or obstinate refusal to acknowledge evident facts. This ordinary usage forms the linguistic backdrop against which Sartre’s resemanticization takes place.
When Sartre adopts mauvaise foi in L’Être et le néant (1943), he preserves the evaluative contrast with bonne foi but shifts the focus from external sincerity in social transactions to an internal structure of consciousness. Later translations and receptions of Sartre’s work often retain the French phrase to signal this technical sense, even when a close vernacular equivalent exists for juridical “bad faith.”
3. Pre-Philosophical and Legal-Theological Usage
Before its existentialist transformation, mauvaise foi and its cognates function primarily within legal, commercial, and theological discourses that emphasize honesty and trustworthiness.
3.1 Roman and Canon Law
Roman jurists use bona fides / mala fides to assess intent and fairness in contracts, property disputes, and fiduciary relations. The good‑faith possessor or contractor is treated differently from one who acts with fraudulent intent or knowingly exploits others. Medieval canon law extends these categories to questions of vows, oaths, and ecclesiastical obligations, where faithfulness and sincerity are morally charged.
3.2 Civil Law Traditions and Early Modern Usage
With the reception of Roman law on the European continent, good faith and bad faith become pervasive standards in civil law codes. In French legal writing, bonne foi expresses a presumption of honesty; mauvaise foi marks cases of wilful deceit, concealment, or opportunistic interpretation of agreements.
“La mauvaise foi se présume rarement; la bonne foi se présume toujours.”
— Traditional French legal maxim (variously formulated in early-modern treatises)
Here “bad faith” is typically an external attribution grounded in observable behavior and presumed intentions, not an introspective structure of self-relation.
3.3 Theological and Moral Contexts
Christian theology, drawing on fides as both trust in God and doctrinal belief, connects “bad faith” to hypocrisy, heresy, or insincere conversion. Moralists sometimes describe the person who swears fidelity while secretly intending betrayal as acting “in mauvaise foi.” The emphasis falls on duplicity before God or others, rather than paradoxical self-deception.
3.4 Everyday French Usage
In non-technical everyday speech up to the early 20th century, accusing someone of mauvaise foi usually implies that they:
- argue in a tendentious or disingenuous manner;
- pretend not to understand obvious points;
- selectively interpret facts to win a dispute.
The phrase thus connotes a strategic unfairness in interpretation or discussion. This pre-philosophical pattern—external, interpersonal, and focused on argumentative or contractual honesty—provides the background contrast for the later existentialist reworking of the term.
4. From ‘Mala Fides’ to ‘Mauvaise Foi’
The shift from mala fides to existentialist mauvaise foi involves both a linguistic continuity and a semantic transformation.
4.1 Continuities: Trust, Sincerity, and Evaluation
Across Latin, medieval, and modern French, “good faith/bad faith” retains an evaluative function. It distinguishes:
| Domain | “Good faith” | “Bad faith” |
|---|---|---|
| Roman law | fair dealing, honest intention | fraud, concealed opportunism |
| Canon law | sincere vows, genuine belief | hypocrisy, insincere profession |
| Civil law | loyal execution of contracts | violation of spirit of agreement |
| Everyday use | openness, willingness to acknowledge facts | tendentious denial, argumentative dishonesty |
This continuity means that when Sartre coins a technical sense, readers already associate the phrase with integrity versus duplicity.
4.2 Early Philosophical Appropriations
Before Sartre, French philosophers do occasionally use mauvaise foi descriptively, but generally in the ordinary moral sense—e.g., to describe dogmatism, sophistry, or religious hypocrisy. It does not yet function as a carefully elaborated concept of self-relation.
4.3 Sartre’s Semantic Reorientation
Sartre’s innovation lies in shifting the focus from interpersonal dishonesty to an inner, phenomenological dynamic in which the same consciousness is both deceiver and deceived. He retains the normative disapproval implied by “bad faith” but:
- decouples it from specific religious or legal frameworks;
- makes it a structural possibility of any consciousness rather than a rare moral vice;
- ties it to the tension between facticity (what one is) and freedom (what one can become).
Thus the movement from mala fides to mauvaise foi can be seen as a transition from external judgments about intent to an analysis of how a subject can flee its own freedom while partially recognizing that it is doing so.
4.4 Later Theoretical Extensions
Subsequent thinkers keep Sartre’s technical sense in view while reintroducing elements closer to the older legal-theological tradition, such as culpable ignorance, ideological rationalization, and public disingenuousness. The historical trajectory therefore loops back: the term that had migrated inward to describe the structure of consciousness is later reapplied to social and political practices, now informed by its existentialist background.
5. Sartre’s Phenomenology of Bad Faith
In L’Être et le néant (Being and Nothingness, 1943), Jean‑Paul Sartre offers the most influential and systematic account of mauvaise foi. It appears within his broader ontology of the en-soi (in‑itself) and pour-soi (for‑itself).
5.1 Structural Definition
For Sartre, bad faith is a paradoxical self-deception in which consciousness both:
- knows itself as freedom (pour‑soi, capable of negation and transcendence), and
- treats itself as a fixed thing (en‑soi) or, conversely, as pure freedom without constraints,
while in some sense being aware that this reduction is false.
“La mauvaise foi est foi. Elle pose comme vrai un certain état de fait, tout en sachant bien qu’il n’en est rien.”
— Jean‑Paul Sartre, L’Être et le néant, Part I, ch. 2
Bad faith is not a simple lie, because there is no distinct deceiver and victim; it is one and the same consciousness.
5.2 Classic Examples
Sartre illustrates this structure through everyday scenarios:
| Example | Bad-Faith Pattern (schematic) |
|---|---|
| Café waiter | Overplays his role, acting “nothing but” a waiter, denying freedom beyond his function. |
| Woman on a date | Leaves her hand in a man’s, neither accepting nor rejecting advances, refusing to interpret the situation. |
| Homosexual man | Denies his homosexuality by appealing either to isolated acts (facticity) or to pure intentions (freedom). |
These examples are meant not as moral condemnations of particular identities but as illustrations of how one oscillates between being a fact and being a project to avoid fully assuming both.
5.3 Conditions and Motives
Sartre links bad faith to anguish (angoisse) arising from the realization of radical freedom. To flee this anguish, consciousness:
- identifies completely with a role, character, or social label (“I am essentially this”);
- or treats itself as pure interior freedom, disowning the weight of its past and situation.
Bad faith is thus a project: a continual interpretive stance toward one’s own being.
5.4 Pervasiveness and Critique
Sartre presents mauvaise foi as a ubiquitous temptation, not a rare pathology. He also rejects standard psychoanalytic explanations of self-deception that posit an unconscious deceiver, arguing instead that bad faith can be analyzed entirely at the level of conscious intentionality, with its shifting attentional focus, half-avowed beliefs, and selective interpretations.
6. Heidegger, Kierkegaard, and Background Influences
Sartre’s account of mauvaise foi emerges against a backdrop of earlier existential and phenomenological analyses, particularly those of Martin Heidegger and Søren Kierkegaard. Although neither uses the term “bad faith,” many scholars view their concepts of falling and despair as important antecedents.
6.1 Heidegger: Falling and Inauthenticity
In Sein und Zeit (Being and Time, 1927), Heidegger analyzes Dasein’s tendency to “fall” (Verfallen) into everydayness and the anonymous “they” (das Man).
Key notions include:
| Heideggerian Term | Brief Characterization |
|---|---|
| Verfallen | Dispersal in distractions, routines, and public norms |
| Gerede | “Idle talk,” unreflective repetition of public discourse |
| Uneigentlichkeit (inauthenticity) | Evasion of owning up to one’s finite possibilities |
“In falling, Dasein is proximally and for the most part along with the ‘world’ of its concern.”
— Martin Heidegger, Sein und Zeit, §38
Commentators often see an affinity between Heidegger’s analysis of how individuals lose themselves in the “they” and Sartre’s description of taking refuge in social roles in bad faith, though Heidegger does not frame this as self-deception in Sartre’s sense.
6.2 Kierkegaard: Despair and Self-Relation
Kierkegaard, especially in The Sickness unto Death (1849), treats despair as a misrelation in the self, which is “a relation that relates itself to itself.” He distinguishes forms of despair:
- Not willing to be oneself (losing oneself in social or finite identities);
- Willing in defiance to be oneself (isolated self-assertion).
“The despairing man is in despair of himself; or he is in despair over his self.”
— Anti‑Climacus (S. Kierkegaard), The Sickness unto Death, Part I
This “double-mindedness” of both knowing and not wanting to know who one is bears strong structural resemblance to Sartrean bad faith, though Kierkegaard’s framework is explicitly theological and oriented toward one’s relation to God.
6.3 Convergences and Divergences with Sartre
Scholars highlight convergences:
- all three diagnose a flight from selfhood or from the burden of existence;
- each analyzes ambiguity in self-relation (knowing yet evading one’s condition);
- social norms and public roles figure as sites of evasion.
They also stress divergences:
- Sartre’s ontology of en-soi/pour-soi differs from Heidegger’s analysis of Being and Dasein;
- Kierkegaard’s despair is inseparable from sin and faith, whereas Sartre secularizes the issue;
- Heidegger and Kierkegaard do not describe the self as a deceiver of itself in exactly Sartre’s manner, nor do they use the language of bad faith.
These background influences thus provide conceptual resources that Sartre adapts and recasts within his own phenomenological vocabulary.
7. Simone de Beauvoir and Ethical Dimensions
Simone de Beauvoir extends the notion of mauvaise foi into the realms of ethics, gender, and social oppression, developing themes only briefly treated in Sartre.
7.1 Bad Faith and Ethical Ambiguity
In Pour une morale de l’ambiguïté (The Ethics of Ambiguity, 1947), de Beauvoir emphasizes that human existence is intrinsically ambiguous: individuals are both subject and object, freedom and facticity. Bad faith arises when one denies this ambiguity:
- by treating oneself as pure object (mere thing, victim, or function), or
- as pure subject (sovereign ego unbound by situation or others).
“L’homme en mauvaise foi cherche à fuir l’angoisse de cette double vérité de son être: il est liberté et il est chose.”
— Simone de Beauvoir, Pour une morale de l’ambiguïté, Part II
Ethically, bad faith manifests as refusal to assume responsibility for this dual aspect of existence and its implications for others.
7.2 Gendered Forms of Bad Faith
In Le Deuxième Sexe (The Second Sex, 1949), de Beauvoir applies this framework to the situation of women. She argues that social myths and institutions encourage women to internalize roles—such as the “eternal feminine,” the mother, the muse—which can be embraced in bad faith when they are taken as absolute destinies rather than historically contingent possibilities.
“On ne naît pas femme: on le devient.”
— Simone de Beauvoir, Le Deuxième Sexe, Introduction
Bad faith here involves both:
- acceptance of oppressive roles as natural or inevitable; and
- denial of one’s own transcendence and the freedom of others.
7.3 Complicity and Oppression
De Beauvoir analyzes how dominated groups and individuals can be complicit in their own oppression through bad faith, for example by:
- clinging to the security of prescribed roles;
- disavowing their capacity for revolt or transformation;
- projecting responsibility exclusively onto external forces.
At the same time, she stresses that this complicity occurs within asymmetrical power relations, making the evaluation of responsibility complex and context-dependent.
7.4 Ethical Responsibility
For de Beauvoir, recognizing and overcoming bad faith is not simply a matter of individual authenticity; it is tied to an ethics of reciprocity. One must acknowledge others as freedoms whose projects interweave with one’s own. Bad faith is thus ethically significant because it undercuts possibilities for mutual recognition, solidarity, and liberation, especially in gendered and other structured contexts of inequality.
8. Conceptual Analysis: Structure of Self-Deception
Philosophers use mauvaise foi to illuminate a distinctive structure of self-deception that differs from ordinary lying or simple error.
8.1 The Paradox of Knowing and Not Knowing
A central puzzle is how one and the same subject can both know and not know some truth about themselves. In bad faith:
- there is enough awareness of the truth (e.g., one’s freedom, motives, or situation) to guide behavior;
- yet the subject averts attention, reinterprets, or compartmentalizes this awareness to avoid its implications.
Different interpretations offer accounts of this paradox:
| Interpretation Type | Characterization of the Structure |
|---|---|
| Phenomenological (Sartrean) | Shifts in attention and perspective, without positing unconscious deception |
| Psychological (inspired) | Motivated biases, selective memory, and rationalization |
| Cognitive-analytic | Conflicting attitudes at different “levels” (occurrent vs. dispositional beliefs) |
8.2 Roles of Attention and Interpretation
Analyses influenced by Sartre emphasize attention management. Bad faith does not require false factual beliefs; rather, it often involves:
- focusing on some aspects of one’s situation (e.g., social definitions) while ignoring others (e.g., one’s capacity to revise them);
- oscillating between different self-descriptions depending on what is convenient to acknowledge.
This dynamic makes bad faith unstable and “slippery,” as the subject constantly adjusts their interpretive stance.
8.3 Self-Identification and Role-Playing
Another structural feature is how individuals identify with social roles, labels, or narratives. In bad faith, a person may:
- reduce themselves to a role (“I am nothing but a parent/employee/official”); or
- disown their role as if it were purely external, denying responsibility for how they inhabit it.
These identifications allow individuals to evade the challenge of integrating their facticity and freedom into a coherent self-understanding.
8.4 Distinguishing Bad Faith from Related Phenomena
Philosophers contrast mauvaise foi with:
- simple mistake: lacks the motivated evasive element;
- hypocrisy: involves conscious deception of others, not necessarily self-deception;
- akrasia (weakness of will): one may act against one’s better judgment without misrepresenting oneself.
Bad faith thus occupies a specific conceptual niche: a motivated, internally divided stance where self-understanding is shaped to shield the agent from anxiety or responsibility.
9. Bad Faith, Facticity, and Freedom
Within existentialist frameworks, especially Sartre’s, facticity and freedom are the twin poles around which bad faith is organized.
9.1 Facticity: What Is Given
Facticity refers to the ensemble of facts about one’s situation that are not immediately chosen:
- bodily characteristics, past actions, social position;
- historical, cultural, and economic conditions.
For Sartre, these are aspects of the en-soi that the pour-soi encounters as limits and conditions.
9.2 Freedom: Transcendence of the Given
Freedom, in this context, is not mere absence of constraint but the capacity of consciousness to negate, reinterpret, and project possibilities beyond its given situation. Even when options are severely limited, Sartre argues that one remains free in the way one takes up those limits.
“Jamais nous n’avons été aussi libres que sous l’Occupation allemande.”
— Jean‑Paul Sartre, “Paris sous l’Occupation” (1944)
This provocative claim underscores his view that even oppressive conditions do not abolish freedom, though philosophers differ on how far this can be sustained.
9.3 Patterns of Bad Faith
Bad faith typically takes two complementary forms:
| Mode of Evasion | Description |
|---|---|
| Facticity-as-essence | One identifies wholly with given facts (“That’s just who I am”), denying freedom. |
| Freedom-as-pure | One disowns past and situation (“I am not responsible; I am only my intentions”), denying facticity. |
In both cases, the ambiguous unity of facticity and freedom is split, allowing the subject to avoid the anguish associated with acknowledging both.
9.4 Philosophical Disputes
Debates center on:
- whether Sartre overstates the absoluteness of freedom, underestimating structural constraints;
- how to conceptualize responsibility when choices are shaped by socialization and power relations;
- whether bad faith is always a moral failing, or sometimes an understandable, even necessary coping mechanism in harsh conditions.
Alternative existential and phenomenological accounts sometimes soften Sartre’s emphasis on radical freedom, proposing more nuanced models in which bad faith involves distorted responses to real constraints, rather than sheer denial of boundless choice.
10. Contrast with Authenticity and Good Faith
The notion of mauvaise foi gains much of its meaning from contrast with both authenticity (in existentialist ethics) and good faith (in legal and everyday senses).
10.1 Authenticity as Existential Counterpart
In existential thought, authenticity is an ideal of living in lucid acknowledgment of one’s freedom, facticity, and relations to others. While definitions vary, authenticity generally involves:
- owning one’s past choices and situation without fatalistic resignation;
- assuming one’s freedom to project new possibilities;
- avoiding self-deceptive reductions of self to a role or pure intention.
Bad faith, by contrast, is characterized by denial, evasion, or splitting of these dimensions. Where authenticity emphasizes clarity and assumption, bad faith emphasizes obscurity and flight.
10.2 Good Faith in Law and Ordinary Morality
Outside existentialism, good faith (bonne foi, bona fides) traditionally refers to:
- honesty in contractual and commercial dealings;
- sincerity and fair-mindedness in social interactions;
- absence of hidden malice or deceitful intent.
Here, bad faith is the straightforward opposite: dishonest, manipulative, or opportunistic behavior. This contrast is primarily external and behavioral, judged by observable conduct and presumed intentions.
10.3 Intersections and Tensions
Sartrean bad faith overlaps but does not coincide with these traditional notions:
| Dimension | Authenticity / Good Faith | Bad Faith (Sartrean) |
|---|---|---|
| Focus | Lucid self- and other-relation; honesty | Evasive self-relation; structured self-deception |
| Level | Ethical ideal or legal norm | Phenomenological structure of consciousness |
| Evaluation | Positive (admired, legally protected) | Negative (but often pervasive or “normal”) |
An individual may act in legal good faith while still in existential bad faith, for example by sincerely fulfilling a role they uncritically accept as their essence. Conversely, someone striving for authenticity might be judged in legal bad faith if they challenge unjust contracts or social norms in ways that breach formal expectations.
Philosophers and legal theorists debate whether and how these senses should be related, with some arguing for a clear separation and others exploring how existential self-deception might manifest in institutional practices labeled “good faith.”
11. Related Concepts: Self-Deception, Ideology, Inauthenticity
“Mauvaise foi” is conceptually linked to several broader philosophical categories. Clarifying these connections helps delineate its specific role.
11.1 Self-Deception
Self-deception generally refers to cases where individuals hold or maintain beliefs contrary to evidence accessible to them, often due to motivated biases. Major questions include:
- how a single agent can both cause and suffer deception;
- whether self-deception requires false beliefs or can involve selective attention to truths.
Sartrean bad faith is often treated as a paradigm of self-deception, but distinctive in its emphasis on:
- existential stakes (freedom, identity, responsibility);
- the dynamic stance of consciousness rather than static contradictory beliefs.
Analytic philosophers sometimes use “bad faith” when they want to retain these normative and existential dimensions within debates on self-deception.
11.2 Ideology and Ideological Blindness
Ideology refers to systems of beliefs and practices that shape how individuals perceive social reality, often stabilizing existing power relations. The link to bad faith appears when:
- individuals or groups ignore or rationalize evidence of injustice;
- they maintain self-exonerating narratives about their roles in oppressive systems.
Thinkers in critical theory and critical race theory describe such stances as forms of collective bad faith, where agents have access to counterevidence yet, through motivated interpretation, preserve comforting self-images.
11.3 Inauthenticity
Inauthenticity broadly designates modes of existence in which individuals do not fully own their possibilities, often conforming unreflectively to social norms. In Heidegger this is analyzed as falling; in Sartre and de Beauvoir, as flight from freedom.
Bad faith is one specific mechanism underpinning inauthenticity: it explains how individuals can actively collude in their own inauthentic self-understanding through selective identification and denial. However:
- one can be inauthentic through heedlessness or habit without explicit self-deceptive projects;
- bad faith, as Sartre defines it, involves a more active and often more reflective distortion of self-relation.
11.4 Comparative Overview
| Concept | Scope | Role of Deception | Relation to Bad Faith |
|---|---|---|---|
| Self-deception | Psychological/moral | Central, often individual | Bad faith as a structurally complex instance |
| Ideology | Social, political, historical | Sometimes implicit or systemic | Bad faith as individual/collective uptake of ideology |
| Inauthenticity | Existential, ontological | May or may not involve deception | Bad faith as a common pathway to inauthenticity |
These relationships show how mauvaise foi operates at the intersection of individual psychology, social theory, and existential ontology.
12. Bad Faith in Feminist and Critical Race Theory
Feminist and critical race theorists have adapted the notion of bad faith to analyze complicity, denial, and ideological justification within systems of gender and racial domination.
12.1 Feminist Uses Beyond de Beauvoir
Building on de Beauvoir, later feminists examine how bad faith can structure:
- internalization of gender norms as natural or inevitable;
- denial of one’s own participation in patriarchal practices;
- rationalization of inequalities as expressions of “choice” or “nature.”
Some authors argue that bad faith helps explain why individuals may actively uphold institutions that disadvantage them, finding psychological security in familiar roles or ideologies.
Others caution that invoking bad faith risks over-moralizing complex survival strategies, especially when options are constrained; they propose distinguishing between strategic accommodation and genuine self-deceptive complicity.
12.2 Critical Race Theory: Racial Bad Faith and White Ignorance
Critical race theorists employ “bad faith” to describe forms of racial denial and selective ignorance. Charles W. Mills, for instance, links “white ignorance” to patterns where:
- members of dominant racial groups avoid acknowledging racial injustice;
- they maintain self-images of fairness by reframing evidence, emphasizing exceptions, or appealing to formal equality.
“White misunderstanding, misrepresentation, evasion, and self-deception… are among the most pervasive phenomena of the racial polity.”
— Charles W. Mills, The Racial Contract (1997)
Here, racial bad faith combines individual motivation with structural reinforcement: social institutions and epistemic practices support denials that are nonetheless, in some sense, culpable.
12.3 Intersections of Gender, Race, and Other Axes
Intersectional analyses note that bad faith can operate differently across intersecting identities. For example:
- a person may resist gender norms while accepting racial hierarchies, or vice versa;
- members of marginalized groups may adopt partial bad-faith narratives to navigate hostile environments, complicating evaluations of responsibility.
Some theorists emphasize how dominant-group bad faith (e.g., patriarchal or white bad faith) interacts with pressures on subordinated groups to conform, rendering the landscape of complicity and resistance highly nuanced.
12.4 Debates and Critiques
Within feminist and critical race theory, discussions focus on:
- whether “bad faith” adequately captures structural and unconscious aspects of oppression;
- to what extent intentionality and awareness are required for calling a stance “bad faith”;
- how to balance critical diagnosis with recognition of limited agency under domination.
These debates illustrate how the concept, originally framed in largely individual-existential terms, is reworked to interrogate collective and systemic forms of denial and justification.
13. Analytic Debates on Responsibility and Self-Deception
In Anglo-American analytic philosophy, “bad faith” features in discussions of self-deception, moral responsibility, and practical rationality, often with explicit reference to Sartre.
13.1 Self-Deception: Models and Puzzles
Analytic philosophers debate how self-deception is possible without violating basic principles of belief. Competing models include:
| Model Type | Key Idea |
|---|---|
| Intention-based | Agent intentionally brings about their own misleading belief |
| Motivational bias | Non-intentional processes (wishful thinking, confirmation bias) produce self-deception |
| Divided mind | Different belief-like states in distinct “centers” or levels of mind |
Proponents sometimes treat Sartrean bad faith as an early articulation of motivated self-interpretation, even though Sartre rejects unconscious mental agencies as explanatory.
13.2 Responsibility and Culpability
A central issue is whether agents are morally responsible for self-deception and bad faith. Views range from:
- those who hold that self-deception, by its motivated nature, entails some degree of responsibility; to
- those who argue that deep-seated socialization, trauma, or structural ideology may diminish culpability.
When “bad faith” is used, it often signals a more evaluatively loaded form of self-deception, where avoidance of truth is tied to moral or political stakes (e.g., complicity in injustice).
13.3 Bad Faith in Moral Psychology and Political Theory
Analytic moral psychologists and political philosophers employ bad faith to examine:
- how individuals maintain self-images as morally decent while acting in ways that harm others;
- processes of rationalization in contexts like racism, sexism, or environmental destruction;
- rhetorical and discursive practices that support collective self-deception.
Authors such as Iris Marion Young and Charles Mills connect Sartrean themes to analytic discussions of structural injustice, using “bad faith” to mark the intersection of epistemic, moral, and political failures.
13.4 Critiques of the Concept
Some analytic philosophers express reservations about “bad faith” as:
- too imprecise, mixing description with moral condemnation;
- overly tied to Sartre’s controversial claims about radical freedom;
- insufficiently attentive to cognitive science accounts of bias and heuristics.
Others defend the term’s usefulness for capturing qualitative differences between ordinary error and motivated, responsibility-laden self-misrepresentation, especially in ethically charged contexts.
14. Translation Challenges and Cross-Linguistic Issues
Rendering mauvaise foi into other languages raises both lexical and conceptual difficulties.
14.1 Legal vs. Existential Connotations
The straightforward translation “bad faith” exists in many legal and everyday vocabularies (e.g., English, Spanish mala fe, Italian mala fede). However, these terms commonly evoke:
- contractual dishonesty;
- overt insincerity in bargaining or testimony.
Translating Sartre’s technical usage with the same phrase risks conflation with these narrower connotations. Some translators retain the French expression to highlight its specialized sense.
14.2 Semantic Gaps and Workarounds
In languages lacking a compact equivalent, translators may employ phrases emphasizing:
- self-deception;
- inauthenticity;
- bad conscience.
Each option captures only part of Sartre’s concept:
| Candidate Term | Captures | Misses |
|---|---|---|
| “self-deception” | knowing-and-not-knowing dynamic | legal/moral resonance of “faith” |
| “inauthenticity” | existential evasion | structural, self-deceptive specificity |
| “dishonesty with oneself” | evaluative tone | ontological background (en-soi/pour-soi) |
Consequently, scholarly literature often introduces explanatory glosses alongside whatever term is chosen.
14.3 Retaining the French Term
Many academic works in English, German, and other languages keep “mauvaise foi” untranslated when discussing Sartre, sometimes alongside “bad faith.” This strategy:
- signals the term’s status as technical jargon;
- avoids premature assimilation to native legal-theological notions;
- but may limit accessibility for readers unfamiliar with French.
14.4 Cross-Linguistic Resonances
Comparative work notes that certain languages have terms partially analogous to existential bad faith—for example:
- German discussions may relate it to “Selbsttäuschung” (self-deception) and “Uneigentlichkeit” (inauthenticity);
- Scandinavian languages sometimes draw on theological vocabulary linked to despair or double-mindedness, echoing Kierkegaard more than Sartre.
Nevertheless, no widely used term fully replicates the cluster of meanings—faith, trust, sincerity, self-deception, and existential evasion—condensed in mauvaise foi, making contextual explanation a recurring necessity in translation and cross-cultural reception.
15. Applications in Politics, Law, and Public Discourse
Beyond philosophy, “bad faith” has become a widely used label in political analysis, legal contexts, and everyday commentary, drawing variably on its legal and existential resonances.
15.1 Political Rhetoric and Negotiation
In politics, accusations of acting in bad faith typically target:
- negotiators who participate in talks without serious intent to compromise;
- officials who publicly endorse principles they privately undermine;
- propagandists who disseminate information they know to be misleading.
Analysts sometimes invoke Sartrean themes to argue that political actors may also deceive themselves, not only others, about their motives or the justice of their causes, blurring the line between strategic hypocrisy and ideological bad faith.
15.2 Law and International Relations
In law, “bad faith” retains a largely technical meaning, associated with:
- breach of the duty of good faith in contract performance and insurance;
- abuse of rights and procedural manipulation;
- lack of genuine intent in treaty-making and diplomatic commitments.
International law, for instance, prohibits entering treaties in bad faith (e.g., with the covert intention not to comply). Some legal scholars draw on existentialist discussions to explore how institutionalized patterns of denial might constitute forms of collective bad faith even when formal conditions of good faith are met.
15.3 Media, Activism, and Online Discourse
In journalism, activism, and online debate, “bad faith” is often used to criticize:
- disingenuous arguments (e.g., “bad-faith questions,” “bad-faith criticism”);
- tactics such as sealioning, moving goalposts, or selective outrage;
- public figures who feign openness to dialogue while remaining impervious to evidence.
Here, the term oscillates between its pre-philosophical sense (dishonest engagement) and a looser adaptation of Sartrean ideas about motivated refusal to confront inconvenient truths.
15.4 Risks of Overextension
Commentators note potential issues with the term’s broad public use:
- frequent accusations of “bad faith” can short-circuit dialogue, by presuming hidden motives;
- the line between genuine misunderstanding and self-serving denial can be hard to draw;
- political polarization may encourage treating opponents’ positions as inherently bad-faith, regardless of evidence.
These concerns raise questions about how to apply a concept originally crafted for phenomenological and ethical analysis to complex real-world disputes while maintaining fairness and nuance.
16. Legacy and Historical Significance
The concept of mauvaise foi has had a lasting impact on 20th‑ and 21st‑century thought, influencing discussions across existentialism, ethics, social theory, and public discourse.
16.1 Position within Existentialism
Within existential philosophy, bad faith serves as a key tool for:
- articulating the tension between freedom and constraint;
- analyzing everyday forms of inauthentic life;
- framing projects of authenticity, responsibility, and ethical commitment.
Sartre’s treatment in Being and Nothingness becomes a canonical reference point for later existential and phenomenological work, even among those who revise his ontology or moderate his claims about freedom.
16.2 Influence on Ethics and Political Theory
The idea that individuals and groups can knowingly evade recognition of their own freedom or complicity has shaped:
- theories of moral responsibility, especially in contexts of systemic injustice;
- feminist and critical race analyses of complicity and denial;
- debates about ideological belief and the psychology of oppression.
These applications extend the notion of bad faith from an individual-existential phenomenon to a framework for understanding collective and institutional behavior.
16.3 Interdisciplinary Reach
Beyond philosophy and political theory, “bad faith” informs:
- literary criticism, in readings of characters and narrators who misrepresent themselves;
- psychoanalytic and psychotherapeutic reflections, despite Sartre’s critique of Freudian models;
- cultural studies, where it is used to analyze media representations and identity performances.
Its resonance across fields stems from its capacity to capture complex patterns of ambivalence, denial, and role-playing in modern life.
16.4 Shifts in Usage Over Time
Historically, the term has undergone multiple shifts:
| Period | Dominant Sense of “Bad Faith” |
|---|---|
| Roman/medieval | Legal-moral: dishonest intent, fraud |
| Early modern to 19th c. | Legal and everyday: insincerity, unfairness |
| Mid-20th c. existentialism | Technical: paradoxical self-deception about freedom |
| Late 20th c. to present | Hybrid: existential, critical-theoretical, and popular uses |
These layers coexist today, so that “bad faith” can simultaneously evoke legal, moral, existential, and political meanings, depending on context.
16.5 Ongoing Relevance
Current debates about identity, responsibility, and structural injustice continue to draw on the vocabulary of bad faith. Some theorists see it as indispensable for capturing forms of motivated moral blindness that are neither mere error nor straightforward malice. Others question whether its evaluative and existential baggage is always appropriate.
Despite such disagreements, the enduring presence of mauvaise foi in scholarly and public discussions indicates its significance as a conceptual lens for examining how individuals and societies handle uncomfortable truths about themselves.
Study Guide
mauvaise foi (bad faith)
In existentialism, a structurally paradoxical form of self-deception in which consciousness flees the anguish of its own freedom and responsibility by reducing itself either to fixed facticity or to pure freedom, while in some sense knowing this reduction is false.
pour-soi and en-soi
Sartre’s ontological distinction between the ‘for-itself’ (pour‑soi)—conscious, self-transcending, negating freedom—and the ‘in-itself’ (en‑soi)—the opaque, fact-like being of things.
facticity and freedom
Facticity is the given, unchosen aspects of one’s situation (past, body, social position); freedom is consciousness’s capacity to negate, reinterpret, and project possibilities beyond the given.
authenticity
An existential ideal of lucidly acknowledging and assuming both one’s facticity and one’s freedom, as well as one’s relations to others, without self-deceptive reduction to roles or pure intention.
self-deception and double-mindedness
Patterns in which a subject both knows and does not know some truth about themselves, often through selective attention, reinterpretation, or compartmentalization (Kierkegaard’s ‘double-mindedness’ is a key precursor).
inauthenticity and falling (Verfallen)
Heidegger’s analysis of Dasein’s tendency to lose itself in everydayness, public norms, and ‘the they’ (das Man), leading to an inauthentic existence characterized by distraction and evasion.
ideology and collective bad faith
Socially embedded systems of belief and practice that structure perception and can sustain motivated denial, ‘white ignorance,’ or complicity in oppression while preserving a self-image of decency.
bonne foi / bona fides vs. mauvaise foi / mala fides
The traditional legal-moral contrast between good faith (honest, sincere, fair dealing) and bad faith (dishonest, fraudulent, opportunistic conduct).
In what ways does Sartre’s concept of mauvaise foi go beyond ordinary notions of dishonesty or hypocrisy? Can you think of an example where someone is in existential bad faith but appears honest and sincere to others?
How does the tension between facticity and freedom structure Sartre’s account of bad faith, and why does he think splitting or denying this tension is so psychologically tempting?
Compare Heidegger’s notion of falling (Verfallen) and inauthenticity with Sartre’s mauvaise foi. To what extent are they diagnosing the same phenomenon, and where do their analyses diverge?
Simone de Beauvoir argues that women can be complicit in their own oppression through bad faith. How does this complicate simple blame, given that oppressive structures also restrict women’s options?
Can collective agents (e.g., states, dominant racial groups) meaningfully be said to act in bad faith, or is mauvaise foi strictly an individual, phenomenological concept?
Is it ever reasonable or even necessary to remain in bad faith to cope with extreme hardship or oppression, or should authenticity always be pursued regardless of cost?
How do translation choices (e.g., leaving ‘mauvaise foi’ in French vs. using ‘bad faith’ or ‘self-deception’) influence how readers understand the concept in different languages and legal cultures?
