The Vertigo of Freedom: Confronting Nothingness in Human Existence
Have you ever stood at the edge of a precipice and felt a strange urge to jump? This unsettling impulse-what Sartre calls "anguish"-reveals something profound about human existence. In "Being and Nothingness," Jean-Paul Sartre's monumental 1943 philosophical treatise, this experience becomes a gateway to understanding our fundamental condition: we are radically free beings condemned to create ourselves in a world without inherent meaning.
The book became the philosophical bible of post-war existentialism, influencing everyone from Albert Camus to Simone de Beauvoir (Sartre's lifelong companion). Its ideas permeated Western culture so thoroughly that even those who've never read Sartre often unknowingly echo his concepts. When celebrities like David Bowie or Lady Gaga speak of authentic self-creation or the burden of freedom, they're channeling Sartrean existentialism. The work's cultural impact was so significant that when Sartre declined the Nobel Prize in 1964, it only enhanced his reputation as someone who lived his philosophy of radical freedom and responsibility.

Consciousness as Nothingness: The For-itself and the In-itself
At the heart of Sartre's philosophy lies a fundamental distinction between two types of being: the "in-itself" (en-soi) and the "for-itself" (pour-soi). The in-itself represents non-conscious being-objects, rocks, trees-which simply are what they are, complete and self-identical. A rock is just a rock; it harbors no inner distance from itself, no self-reflection. It exists in absolute fullness and identity with itself.
Human consciousness, by contrast, is the for-itself-a type of being that is never identical with itself. When I'm aware of something, I'm simultaneously aware that I'm aware. This self-consciousness creates a gap, a nothingness at the core of our being. I am never simply what I am; I always stand at a distance from myself. When I say "I am sad," I'm not sad in the way a rock is a rock. My sadness is something I experience, something I have a relationship with, something I can question or affirm.
This inner distance-this nothingness-is what makes human freedom possible. Unlike objects that are determined by causal laws, consciousness can nihilate (negate) what is and imagine what is not. When I look at my current situation, I can envision alternatives and possibilities. I can say "no" to what is and project myself toward what could be.
Consider how you experience time. The past exists as what you were but no longer are. The future exists as possibilities you project but haven't yet realized. The present is this constant movement of transcending what you are toward what you will be. This temporal structure reveals consciousness as a perpetual surpassing of itself-never coinciding with itself, always "not being" what it is and "being" what it is not.
This nothingness isn't some mystical void but the very structure of human reality. It's what allows us to question, to imagine, to create. When you ask yourself, "Should I change careers?" or "Should I end this relationship?", you're experiencing this nothingness-this ability to step back from what is and envision alternatives.

The Look and Being-for-Others: The Third Dimension of Existence
Imagine you're peeping through a keyhole, completely absorbed in what you're watching. Suddenly, you hear footsteps behind you. In that moment, you experience yourself as seen-as an object for another consciousness. This is what Sartre calls "the Look." This visceral experience fundamentally alters your mode of being, shifting you from subject to object in an instant.
The Look reveals a third dimension of being beyond the for-itself and in-itself: being-for-others. Through the Other's gaze, I discover myself as having an outside that escapes me. I am suddenly aware of myself as having characteristics I cannot directly experience-being tall, awkward, intrusive. The Other holds a perspective on me that I can never fully access. This perspective is not just physical but encompasses social and moral dimensions as well. When someone sees me as "rude" or "kind," they're capturing aspects of my being that I cannot directly apprehend.
This creates a fundamental conflict. As a for-itself, I experience myself as freedom, as transcendence. But under the Other's Look, I become fixed as an object with definite properties. My freedom is threatened; I am "petrified" by the Other's gaze. I become what Sartre calls a "transcendence-transcended"-my freedom is captured and objectified. This objectification is not merely passive but actively shapes how I understand and experience myself.
Consider how you feel when giving a presentation and suddenly become self-conscious. Your fluid, spontaneous engagement with your material transforms into awkward awareness of how others might be judging you. Your freedom is alienated; you experience yourself as an object exposed to others' evaluations. This self-consciousness can manifest in physical symptoms: stumbling over words, sweating, or forgetting your prepared speech. The Other's gaze has transformed your natural flow into mechanical self-monitoring.
This creates an inescapable conflict at the heart of human relationships. Either I must transcend the Other's freedom by making them an object for me, or I must allow myself to be transcended and objectified by them. This dialectic plays out in all human relationships, from love to indifference to hatred. In love, for instance, we desire both to possess the Other's freedom while simultaneously wanting them to freely choose us - an impossible contradiction that Sartre argues dooms all relationships to conflict.
The Look doesn't require actual others to be present. Even alone, I can experience myself as potentially visible to absent others. This explains why I might feel embarrassed when alone-I've internalized how others might see me. The very structure of my being includes this dimension of being-for-others, whether or not others are physically present. This internalization manifests in everyday behaviors: adjusting our clothes before leaving home, rehearsing conversations in our heads, or feeling shame about private actions. The Other's gaze becomes part of our psychological structure, shaping our behavior even in solitude.
This perpetual tension between our freedom and our objectification by others creates what Sartre calls "bad faith" - attempts to escape this fundamental structure of human existence. We might try to deny either our freedom or our object-status for others, but both attempts are ultimately futile. We are condemned to exist simultaneously as both subject and object, free consciousness and thing-for-others.

Bad Faith: Fleeing from Freedom
If human beings are fundamentally free, why do we so often feel determined, constrained, or defined by our circumstances? Sartre's answer: bad faith (mauvaise foi)-a form of self-deception where we deny our freedom and responsibility.
Bad faith takes two primary forms. First, we can deny our transcendence by reducing ourselves to facticity-the given aspects of our situation we didn't choose (our past, our body, our social position). This is the waiter who plays at being "just a waiter," mechanically performing his role as if he were nothing more than his function. He pretends to be a thing, denying his freedom to transcend his role.
Second, we can deny our facticity by pretending to be pure transcendence-as if we had no concrete situation limiting our possibilities. This is the woman who, when a man takes her hand during a date, leaves her hand there "as a thing," pretending not to notice. She floats above the situation, refusing to acknowledge her body as part of her being.
Consider how often we say things like "I couldn't help it" or "That's just how I am." These are classic expressions of bad faith. When I say "I have a bad temper; that's just my nature," I'm pretending my anger is like a physical attribute I can't change, rather than something I choose and maintain. I'm treating my freedom as if it were a thing.
Bad faith isn't simple lying-it's more insidious because I'm both deceiver and deceived. I must know the truth to hide it from myself. This creates a fascinating paradox: I must be aware of my freedom precisely in order to flee from it. Bad faith thus contains its own contradiction-it's a belief that doesn't believe in itself.
Why engage in bad faith? Because freedom is terrifying. To acknowledge my radical freedom means accepting that nothing determines my choices-not my past, not social norms, not others' expectations. I alone am responsible for what I make of myself. This produces anguish-the vertigo of confronting unlimited possibilities with no external guidance.

The Body: Existing as Embodied Consciousness
Against Cartesian dualism, Sartre insists that consciousness is fundamentally embodied. I don't "have" a body; I am my body. My body isn't an external object I possess but the concrete form of my being-in-the-world. This embodiment is not optional or secondary but constitutes the very foundation of human existence and experience.
However, my body exists in three distinct dimensions, each revealing a different aspect of embodied consciousness. First, there's my body as I live it-my body-for-me. This isn't the body I observe or know objectively, but the body I am as I engage with the world. When I reach for a glass, I don't calculate distances or muscle movements; I simply reach. When I type on a keyboard, my fingers move naturally without conscious thought about their position. My body disappears into its actions. It's not something I have but something I live through, the invisible center from which I experience the world.
Second, there's my body-for-others-how my body appears to other people. This is my body as object, with characteristics I can't directly experience: how I look from behind, whether my voice sounds pleasant, whether my movements appear graceful. A dancer may feel fluid and light while performing, but cannot see their own performance as others do. A speaker may feel their voice resonating internally but cannot hear it as their audience does. This dimension of my body always escapes me; it belongs to others' perspectives.
Third, there's my alienated body-how I experience my body as others see it. When I become self-conscious about my appearance during a conversation, I'm experiencing my body as it exists for others. I feel "fat" or "awkward" not through direct experience but by adopting others' perspectives on my body. This dimension emerges particularly in moments of social anxiety or self-consciousness, when we become hyper-aware of our physical presence through imagined external perspectives.
These dimensions create a complex relationship with embodiment. My body is simultaneously the center of my world, an object for others, and something I experience as alienated from myself. This helps explain phenomena like shame, where I experience my body as exposed and objectified under others' gazes. Consider how a teenager might feel completely comfortable dancing alone in their room, but become paralyzed with self-consciousness on a dance floor.
The distinction between these dimensions becomes clear in everyday situations. Consider how differently you experience your body when alone versus in public. Alone, your body simply exists as your point of view on the world - you might stretch, slouch, or move without any self-consciousness. In public, you become aware of how others might see you-your posture, your clothing, your mannerisms. A simple act like eating becomes layered with social awareness: the private experience of taste and hunger meets the public performance of "proper" dining etiquette. This shift reveals the fundamental difference between the body-for-itself and the body-for-others, highlighting how our embodied existence is always negotiating between these different modes of being.

Human Relationships: The Fundamental Conflict
If the Look transforms me into an object, how can authentic relationships exist? Sartre's analysis is famously pessimistic: all relationships involve conflict because each consciousness seeks to preserve its freedom while capturing the other's.
Love illustrates this paradox perfectly. As a lover, I want the beloved to freely choose me-a mechanical puppet programmed to love me would not satisfy. Yet I also want to possess their freedom, to become the center and limit of their world. I want them to freely choose to make me their prison.
This creates an impossible situation. If the beloved maintains their freedom, they remain capable of choosing someone else. If they surrender their freedom to me, they're no longer the free being whose love I sought. Love thus contains a contradiction: I want the Other's freedom to freely surrender itself while remaining freedom.
Sexual desire similarly aims at an impossible goal: to possess the Other's consciousness through their body. In caressing the beloved's body, I seek to make their consciousness "incarnate" itself, to become pure flesh. Yet consciousness can never be reduced to flesh; it always transcends the body. The moment of orgasm provides a fleeting illusion of fusion that inevitably collapses back into separation.
Other relationships follow similar patterns. In masochism, I try to escape my subjectivity by becoming a pure object for the Other. In sadism, I try to capture the Other's freedom by reducing them to a mechanical body. In indifference, I pretend others are mere objects with predictable functions. All these strategies ultimately fail because they cannot resolve the fundamental contradiction: two freedoms cannot simultaneously capture each other without destroying what they seek to possess.
This doesn't mean all relationships are doomed, but it does mean they contain inherent tensions that cannot be permanently resolved. Authentic relationships might involve recognizing and accepting this conflict rather than trying to escape it.

Freedom and Facticity: The Situation
If we're radically free, why do we feel constrained by our circumstances? Sartre's answer: freedom always exists in situation. Freedom isn't abstract but concrete-it's always freedom to do something specific in a particular context. This situatedness of freedom is fundamental to understanding how we experience and exercise our choices in the world.
My situation encompasses several key elements that shape my existence: my place (where I am physically and socially positioned), my past (the accumulation of choices, experiences, and circumstances that have brought me to this point), my environment (both natural and built surroundings that form the context of my actions), my fellow humans (the complex web of relationships and social structures I'm embedded in), and my death (the ultimate horizon that gives temporal structure to all my choices). These elements constitute my facticity-the given aspects of my existence I didn't choose but must confront.
However, facticity doesn't limit freedom; rather, it's the necessary condition for freedom to exist at all. Freedom without facticity would be empty and meaningless, like trying to write without paper or paint without canvas. I need something to transcend, something to say "no" to, something to transform. My facticity provides the raw material my freedom works with, creating the concrete situation within which meaningful choices become possible.
Consider a mountain climber facing a difficult cliff. The cliff's steepness is an objective fact, but whether it appears as "too steep" or "challenging but climbable" depends on the climber's project. If they're determined to reach the summit, the cliff appears as an obstacle to overcome, perhaps even as an exciting challenge. If they're just out for a pleasant hike, the same cliff might appear as a reason to turn back. If they're a geologist, it might appear as an interesting formation to study. The factual steepness acquires meaning only in relation to the climber's freely chosen project and their self-conceived identity.
Even extreme situations like imprisonment or torture don't eliminate freedom, though they severely constrain it. The prisoner remains free to resist, to accept, to attempt escape, to maintain dignity, or to commit suicide. A political prisoner might transform their confinement into a testament to their cause, while another might use it as time for self-reflection. Their freedom is situated-constrained by concrete limits-but not eliminated. The meaning of these constraints depends on how the prisoner's freedom engages with them and what project they pursue within these limitations.
This reveals a crucial paradox: I am wholly responsible for my situation, yet my situation includes elements I didn't create or choose. I didn't choose to be born in this time and place, with this body and this past, yet I'm responsible for what I make of these givens. A person born into poverty didn't choose their economic circumstances, but they are responsible for how they interpret and respond to that situation. My freedom doesn't create facticity, but it determines its meaning through the projects I choose to pursue and the values I choose to embrace.
The relationship between freedom and facticity is thus dialectical: each requires the other to be meaningful. Our freedom is always exercised within constraints, but these constraints only become meaningful through our free projects and choices. This understanding helps explain why different individuals can face similar circumstances yet respond to them in radically different ways.

The Fundamental Project: Understanding Human Choice
Why do people make the choices they do? Sartre rejects both deterministic explanations (which deny freedom) and purely rational explanations (which ignore the deeper unity of a person's choices). Instead, he proposes that each person has a fundamental project-an original choice of being that gives meaning to all their specific choices. This concept forms the cornerstone of Sartre's understanding of human behavior and motivation.
This fundamental project isn't chosen reflectively or deliberately. It's pre-reflective-more basic than conscious deliberation. It's the way I choose my being-in-the-world as a totality. All my specific choices-career, relationships, hobbies-express this more fundamental choice. Like a lens through which we view and interpret the world, it colors every decision we make, often without our conscious awareness.
For example, a person might fundamentally choose themselves as striving to overcome contingency through achievement. This fundamental project would give meaning to their specific choices: working long hours, prioritizing career over relationships, seeking recognition. Their choice of profession, their competitive nature in sports, even their approach to friendships would all reflect this core project. Another person might choose themselves as creating harmony and connection, leading them to prioritize relationships, seek collaborative work environments, and find fulfillment in community service.
The fundamental project isn't determined by my past or environment, but it's not arbitrary either. It represents my original response to the human condition-to the fact that I exist without having chosen to exist, that I must create meaning in a world that offers no predetermined meaning. This response shapes how we cope with anxiety, face challenges, and pursue goals. Some might respond by seeking control through knowledge, others through artistic expression, and still others through building lasting institutions.
Existential psychoanalysis aims to uncover this fundamental project. Unlike Freudian psychoanalysis, it doesn't reduce choices to unconscious drives or childhood traumas. Instead, it seeks to understand how specific behaviors express a person's original choice of being. Even seemingly trivial preferences-for slimy or solid foods, for mountains or oceans-can reveal aspects of this fundamental project. A preference for solid, unchanging landscapes might reflect a deeper desire for stability and control, while an attraction to the ever-changing sea might indicate a fundamental project oriented toward embracing change and uncertainty.
The ultimate goal of all fundamental projects is to become what Sartre calls the "in-itself-for-itself"-a being that would be both solid and self-aware, both complete and conscious. This impossible ideal corresponds to the traditional concept of God-a being that is its own cause, both perfect substance and perfect consciousness. Human desire ultimately aims at this impossible synthesis. We see this manifested in various ways: the scientist's quest for complete knowledge, the artist's attempt to capture perfect beauty, or the spiritual seeker's search for absolute truth. Each represents a different approach to this fundamental human aspiration, though Sartre maintains that its ultimate fulfillment remains impossible.
This tension between our aspirations and their ultimate impossibility creates the distinctive character of human existence - a perpetual striving that gives life its meaning while never reaching final completion. The recognition of this paradox is crucial for authentic self-understanding and acceptance of our human condition.
第 9 章
The Useless Passion: The Impossibility of Self-Coincidence
Sartre's conclusion is stark: the human project is fundamentally a "useless passion." We strive to become the impossible synthesis of in-itself and for-itself-to be both solid being and free consciousness, both determined and self-determining. This project must fail because it contains a contradiction.
Consider how we pursue this impossible goal. Through possession, we try to extend our being by incorporating objects into ourselves. Through knowledge, we try to capture the world without destroying its objectivity. Through artistic creation, we try to produce objects that embody our subjectivity. All these efforts aim at the same impossible goal: to be both subject and object, both freedom and thing.
This doesn't mean human life is meaningless or that our projects have no value. Rather, it means we must create meaning without the guarantee of any external validation. We must accept that our freedom is absolute but never complete-we can never coincide with ourselves or achieve final fulfillment.
The recognition of this "useless passion" might lead to despair, but it could also lead to authenticity-accepting our condition without illusions or evasions. If I acknowledge that I can never become the solid, self-identical being I desire to be, I might embrace my freedom more fully, creating meaning while accepting its contingency.
Sartre hints that an authentic ethics would involve abandoning the "spirit of seriousness"-the belief that values exist independently of human choice. It would mean recognizing that values exist only through our freedom, that we create meaning rather than discovering it. This doesn't make values arbitrary; it makes them human-expressions of our freedom rather than external commands.
The final paradox is that even this recognition-that the human project is a useless passion-doesn't free us from pursuing it. We continue to seek self-coincidence even while knowing it's impossible. This is the human condition: to be a being that can never be what it is and is always what it is not-a perpetual question mark in the heart of being.
