In-itself

In-itself is the self-contained mode of being that simply is what it is, independent of consciousness and without an internal relation to anything else. Yet it is not merely a remote metaphysical category: it is the being encountered in the world, the fixed reality into which the past sinks, and the resistance upon which action depends. Sartre’s account makes the In-itself both radically distinct from consciousness and indispensable to its existence and freedom.

Definition and Contrast with Consciousness

The In-itself is not a substance that must be perceived or represented in order to exist. A past event, for example, does not come into being because someone later recalls it. A person’s past enters the world because that person was it; psychological representation is a way of apprehending an already existing past, not the source of its being. In this respect the past, once fixed, resembles things in the world: it is what it is and refers only to itself.

This self-identity differs from the For-itself, which exists through a relation to being and through its own internal negation. The being of phenomena as In-itself needs only itself; it does not depend on a consciousness to sustain it. The For-itself, by contrast, is not a self-contained substance. It exists in an ontological relation to the In-itself, and its being is bound up with its relation to what is other than itself. The relation is constitutive of the For-itself, not of the In-itself: consciousness is responsible for its own relation to being, while the being it encounters is not made dependent on consciousness by that encounter.

The contrast is not a division between two independent substances that are later joined. Sartre rejects both the idea that external being acts upon an isolated consciousness and the idea that consciousness constructs external being out of its own subjective materials. The concrete is a synthetic totality whose articulations include consciousness and phenomena. Within that totality, however, the In-itself retains its independence: it does not need the For-itself in order to be.

The Past as In-itself

The past makes the In-itself’s fixity especially clear. A person has to be their past, but cannot undo or add to its content. What happened has exhausted its possibilities; unlike a future possibility, it cannot still be achieved or abandoned. The person assumes responsibility for this past as their own, yet cannot cease to have been it. Its meaning may be changed through a later relation to it, but its content remains unalterable.

This fixed past is not simply value. It can resemble value because a former For-itself is preserved together with the meaning it once had as consciousness, but in value the For-itself surpasses and founds its being. The past reverses that movement: the For-itself is reapprehended and fixed by the In-itself. A former grief, for instance, no longer exists through the living self-witness of present consciousness; it remains as a quality of what has been, as fixed as the grief of another or of a statue. The past is thus a contingent fact that must be acknowledged, not an imperative from which a present course of action can simply be deduced.

The passage of a present into the past is not the preservation of the vanished present as an image. The former present becomes In-itself, while the appearance of a new present involves the nihilation of that In-itself. What is past has become what it was, and the past is the being of the present. A past sadness, for example, is no longer sustained as the person’s present act of experiencing it; it has become a fixed feature of what that person was. The past therefore functions as a kind of reversed fatality: the For-itself remains free to make itself, yet cannot escape being, for a new For-itself, what it has made of itself.

Presence, Body, and Situation

The present is not a reciprocal relation between self-contained things. An In-itself cannot be present to another In-itself; it simply is. Presence is an internal ontological relation in which the For-itself is present to being-in-itself. In being present to a table, a room, a city, or the world, consciousness is not merely adjacent to these things. Its presence involves being related to them while not being them. This presence to being is an essential structure of the For-itself, not an accidental connection added after consciousness already exists.

The For-itself’s presence extends to the totality of being-in-itself. Its facticity means it is situated here rather than elsewhere, but that location determines only the perspective from which its presence to the whole is realized. The things of the world appear together as co-present because the For-itself relates them within a world. The In-itself does not itself supply this unity as a conscious act; rather, its independent being is disclosed within the For-itself’s mode of presence.

The body articulates the same entanglement of independence and relation. Human reality necessarily exists as an engaged, contingent being among other contingent beings; the body is not an arbitrarily attached object or the result of combining two radically distinct substances. It is the contingent form assumed by the necessity of the For-itself’s contingency, and it is inseparable from its situation in the world. The body is not an In-itself lodged inside consciousness. It is the For-itself’s fact of not being its own foundation, lived as engagement among things.

The body is also continually surpassed. In perceiving a glass, a table, or a distant tree, a person is immediately present where the object is perceived, while the body functions as the point of reference from which distances appear. It is likewise the point of departure that a project leaves behind as it moves toward a new arrangement of things. In this sense the body is the immediate past that still touches the present: a necessary given that is continually surpassed, but never grasped as a fully detached object by the For-itself. The In-itself reapprehends the For-itself in the very act by which the latter escapes it.

Independence, Resistance, and Freedom

The In-itself is necessary to action precisely because it is independent of the person acting on it. An action can reveal the existence of things but does not create their existence or make them dependent on that action. To be free is to be free to change something: there must be obstacles to overcome, tools to use, and a world that does not require the agent’s action in order to continue existing. If the world were only an extension of the agent’s will, action and resistance would lose their meaning.

Freedom discloses things as obstacles, tools, and resistances by interpreting their significance in light of a chosen end. It does not make their brute existence depend on that interpretation. A project gives the environment a practical meaning, but it works upon realities whose existence is indifferent to the project. The very idea of doing therefore implies a resisting world: freedom is not freedom outside the In-itself but freedom exercised among beings that can withstand or frustrate it.

The world’s order likewise involves both necessity and contingency. It is necessary that the world appear in ordered relations to the For-itself, while it is contingent that the order should take precisely this form. Sartre describes this order as the body at the level of the For-itself: an expression of the agent’s situation, not an In-itself contained within consciousness. The For-itself is at once responsible for how a situation is organized and unable to justify the brute fact that it exists in that situation.

The In-itself and the World

Things are not first received as fully available presences and then given meaning by an additional mental operation. They disclose what they can be for a project through a gesture or act directed toward the future. The For-itself’s nihilation establishes the relations through which things appear as a world, including space, time, possibilities, and practical connections. Its freedom makes things appear as indifferent, unpredictable, adverse, and usable, while leaving their being independent of consciousness.

This dependence of disclosure on freedom does not make the In-itself a product of freedom. Freedom is separated from things by nothingness, yet the things remain out of reach and independent. The For-itself’s project organizes them into a situation and encounters their resistance there; it does not supply their existence. Sartre can therefore maintain both that freedom causes there to be things as disclosed within a world and that those things exist as brute reality, without being conditioned by the consciousness or action that reveals them.

The In-itself is thus the ungrounded plenitude that consciousness can neither absorb nor abolish. It fixes what has been, provides the independent terms toward which consciousness is present, and gives action a resistant field in which choices can take effect. Its contrast with the For-itself is not a route away from the world but the condition for having a world at all: without the In-itself, there would be no independent being to encounter, no past to assume, and no resistance against which freedom could act.
