Bad faith (mauvaise foi) is Jean-Paul Sartre’s term for the ways human beings deceive themselves about their own freedom. Introduced in Being and Nothingness (1943), the concept describes a structure deeper than ordinary lying: bad faith is what happens when a person — while relying on their freedom to function at all — simultaneously denies that they are free. This can mean collapsing into the identity given by a role, a diagnosis, or a social position, as though those circumstances fully determine who one is. It can also mean the opposite: pretending to be pure spirit untouched by circumstances, evading the real constraints of one’s situation. Both moves falsify the human condition, which is always both. For medicine, bad faith names a risk that appears on both sides of the clinical encounter: in how patients understand their illness, and in how clinicians understand their role.
The Problem Bad Faith Solves
Sartre’s for-itself is defined by self-presence rather than self-coincidence, involving an infinitesimal internal distance between consciousness and itself.(Sartre, Jean-Paul, 1943) This internal distance, a nothingness at its core, makes self-awareness possible without consciousness becoming an object to itself.(Sartre, Jean-Paul, 1943)
Anxiety (angoisse) is the specific mood in which freedom reveals itself: in anxiety, a person apprehends themselves as the groundless source of their own choices, with no prior determination settling what they will do.(Sartre, Jean-Paul, 1943) Nothing compels the choice from outside; nothing compels it from inside either, because the “inside” is itself constituted by the choice. This is not a pleasant discovery. The permanent possibility of flight from anxiety is what makes bad faith pervasive: it is the default mode of human existence, not a deviation from it.
Sartre’s Analysis
Bad faith is a self-deceptive mode of existence in which a person denies their freedom by pretending to be a fixed object (être-en-soi) rather than a free consciousness (être-pour-soi), often through contradictory self-interpretations.(Sartre, Jean-Paul, 1943)
Sartre identifies two main forms. In the first, a person absolutizes their facticity: they treat the role, the past, the diagnosis, the social position as their essence, as though it fully determines what they are and can do. In this form, the person says in effect: “I have no choice, because this is what I am.” But this pretends that the for-itself can coincide with itself the way a thing does — and it cannot, because it is always already beyond its facticity toward new possibilities.(Sartre, Jean-Paul, 1943)
In the second form, a person absolutizes their transcendence: they deny their facticity entirely, treating themselves as pure freedom unencumbered by circumstance, past, or social position. This is equally bad faith, because freedom is never freedom from a situation — it is always freedom within one. The situation is the material that freedom must surpass; without it, the concept of freedom has no content.(Sartre, Jean-Paul, 1943)
Both moves deny the fundamental ambiguity of the for-itself, which is always both facticity and transcendence at once — neither a thing nor a pure spirit, but a being that is what it is in the mode of not being it. Sartre closes his treatment of bad faith in Part One with a note on authenticity: the escape from bad faith requires what he calls a radical conversion, in which corrupted being reclaims itself — but its full description belongs elsewhere, in a work on ethics he did not complete.(Sartre, Jean-Paul, 1943)
Bad Faith vs. The Freudian Unconscious
Sartre’s analysis of bad faith includes a pointed critique of Freudian psychoanalysis. The Freudian model tries to explain self-deception by positing an unconscious that hides things from consciousness. But this creates its own paradox: the censor that represses must know what it is repressing, in order to repress it rather than allow it through, and must therefore be conscious of the very thing it is preventing from entering consciousness.(Sartre, Jean-Paul, 1943) The Freudian topology of id, ego, and superego does not dissolve the paradox of bad faith; it restates it at a different level.
For Sartre, bad faith is not something that happens to consciousness from a mechanism outside it. It is something consciousness does — a spontaneous and paradoxical denial of its own freedom, simultaneously requiring and concealing that freedom. The person in bad faith is not deceived by something else; they are the deceiver and the deceived at once. This is what makes bad faith philosophically interesting and therapeutically relevant: it cannot be removed simply by revealing the hidden content, because the person knows, at some level, what they are concealing.
Ordinary introspection is not immune. Sartre’s account of impure reflection describes how standard self-examination distorts what it examines: by positing emotions, desires, and moods as psychic objects — things with stable properties — impure reflection hypostatizes the fluid activity of consciousness into a false interior substance, producing the illusion of a fixed character or personality.(Sartre, Jean-Paul, 1943) Even identifying with one’s own ego — treating the self as a known entity with predictable traits — is a form of bad faith, because the Ego is constituted by reflection after the fact, not the living subject of experience.(Sartre, Jean-Paul, 1943)
The Waiter Example
Sartre’s most famous illustration of bad faith is the Parisian waiter who “plays at being a waiter” — performing his role with an excessive, slightly mechanical precision, as though waitering were not something he freely chooses each morning but his very essence, a nature he could not abandon.(Sartre, Jean-Paul, 1943) The waiter is not lying; he may not be aware of what he is doing. He is simply inhabiting the being-in-itself of a social object while being (as consciousness) always already beyond it.
Clinical Relevance
Bad faith is not a clinical diagnosis, but it describes recognizable configurations in both patients and practitioners.
A patient who responds to a chronic illness diagnosis by collapsing entirely into the sick role — “I am a diabetic, I cannot do otherwise” — is in bad faith to the degree that this response closes off possibilities that remain genuinely open. The diagnosis is a fact of facticity; it enters the situation as something given. But how that facticity is taken up — whether as a closed determination or as a constraint within which freedom still moves — is not settled by the diagnosis itself.(Sartre, Jean-Paul, 1943)
Equally, a patient who denies that their illness places any real constraints on their life — refusing to acknowledge facticity at all — is in the opposite form of bad faith. Freedom is not freedom from the body’s limits; it is freedom within them.
Clinicians are not exempt. A practitioner who identifies entirely with their professional role — “I am simply doing what my training requires, following the protocol” — has made their function into their essence, treating the role as determining what they do and thereby evading the responsibility that their freedom continues to entail.(Sartre, Jean-Paul, 1943) The Look is relevant here too: the medical examination places the patient’s body in the second ontological dimension, as an object for the clinician’s perception.(Sartre, Jean-Paul, 1943) How this objectification is managed — whether the person remains visible within the patient — is a question bad faith can help to frame, even if it cannot by itself answer it.
Bad Faith and the Sick Role
The sociologist Talcott Parsons’s concept of the sick role — where illness legitimizes withdrawal from normal responsibilities, conditional on seeking treatment and wanting to recover — can be read through Sartre as a socially organized form of bad faith. The sick role grants facticity (the illness) an authority over the person’s choices that Sartre would not allow. This is not simply a criticism of patients: the sick role is also a product of how clinical institutions structure the encounter, and of how medicine has historically treated patients as objects for diagnosis and management rather than as free subjects in a situation.(Sartre, Jean-Paul, 1943)
Sartre’s own account does not easily map onto therapeutic recommendations. He did not offer a technique for moving from bad faith to authenticity — the promised work on ethics was never completed.(Sartre, Jean-Paul, 1943) What he offered was a description of what is happening when a person denies their freedom, and an insistence that the denial is always already available to be seen through — not because there is a hidden healthy self waiting to emerge, but because the for-itself is always already beyond what it currently tells itself it is.
Criticism
Sartre’s account of bad faith has been criticized on several grounds. The most persistent objection is that his account of radical freedom is implausible: people in conditions of severe poverty, trauma, or illness may face constraints that are not merely “facticity to be surpassed” but genuine limitations on the range of choices available.(Sartre, Jean-Paul, 1943) Sartre’s own response — that freedom is always the freedom to interpret and take up one’s situation, not freedom from it — can seem to place an impossible burden of responsibility on people whose situations are genuinely constrained.
A second objection, developed within existential psychiatry, is that Sartre’s ontology of irreducible conflict between consciousnesses may be too pessimistic about the clinical relationship. R.D. Laing’s concept of ontological security drew on Sartre but modified his account: some forms of encounter may confirm rather than threaten the patient’s sense of their own reality.(Laing, R. D., 1960) Sartre’s structural claim that all encounters with others involve conflict was a starting point for Laing, not a conclusion.
Human Notes
Sartre wrote the analysis of bad faith in 1941–43, in occupied Paris, while himself making daily choices about how to live under conditions of extreme political constraint. The question of whether one has “no choice” — because the circumstances are overwhelming, because one is only following orders, because this is simply how things are — was not abstract for the people reading Being and Nothingness when it appeared. Whatever one makes of the philosophical arguments, they emerged from a specific historical situation in which bad faith had taken on a face.
