Immanence illusion

The Immanence illusion is the idea that an image is a small likeness lodged inside consciousness and that the thing it represents is reached only indirectly, through that likeness. Jean-Paul Sartre names this error as a consequence of thinking about consciousness spatially, as though it were a container. His alternative is that an image is not an inner object: it is a way consciousness relates to an object. The distinction reshapes the account of mental imagery, perception, and aesthetic experience alike.

Definition and Method

The illusion begins when consciousness is pictured as a place populated by imitations, with the image inside and its object outside. On this model, having an image of a person seems to mean possessing a mental portrait, while the person represented is referred to only because the portrait stands for them. The image is thereby treated as if it were a material object embedded in a mental space.

Jean-Paul Sartre’s method for correcting this picture begins with reflection. When someone produces an image of Pierre, Pierre—not an inner portrait—is the object of the current consciousness. As long as that consciousness remains directed toward Pierre, it can describe him as he appears in the image, but it does not yet describe the image as an image. That requires a second act of consciousness, which turns attention from the represented object to the way it is given. Reflection makes possible the judgment that one has an image.

This reflective description is distinguished from explanatory hypotheses about how images work. A person who reflects and recognizes that they are having an image, the account argues, has certain data; theories about the image’s underlying nature remain probable rather than certain. Jean-Paul Sartre attributes the diversity of psychological doctrines in part to psychologists’ failure to make this immediate knowledge explicit. The proposed first task is therefore to describe and classify the image’s characteristics before explaining its nature.

The Inner Portrait and the Object Outside Consciousness

David Hume’s account illustrates the spatial model. Ideas are described as faint images of impressions, and the idea of an object is treated as the idea itself, with its reference to an external object added from outside. Applied to a chair, this makes the idea of a chair and the chair as an idea effectively one: the idea must possess determinate qualities just as the object does. What seems to follow is that having an idea of a chair means having a chair within consciousness.

The familiar example of a portrait of Pierre shows how readily this assumption takes hold. On the mistaken account, the portrait is what consciousness immediately contains; Pierre, the living person, is reached only indirectly as what the portrait represents. A viewer can also attend to the portrait as a picture without attending to the person it depicts. These different ways of looking make it tempting to identify the image with a material likeness and to treat the represented person as external to it.

The cost of that identification is a rupture in the unity of consciousness. A material portrait is opaque and heterogeneous to consciousness; inserting such objects into a unified stream would break its continuity and transparency. Even theories that make the image lively, or enrich it with feeling and knowledge, leave it as an alien object in the mind. Some thinkers consequently deny that mental images exist at all, in order to preserve the integrity of psychological synthesis. But the ability to imagine a horse, a tree, or a house at will, Jean-Paul Sartre argues, conflicts with that denial and directs inquiry back to what reflection discloses.

The alternative can be seen by comparing perception and imagination of the same straw-bottomed chair. When the chair is perceived, it is not inside the perception; when the eyes close and the chair is imagined, it does not enter consciousness as an imitation chair either. In both cases the object is that same concrete chair, outside consciousness in the room, in front of the desk. What changes is the relation of consciousness to it: in perception the chair is encountered, whereas in imaging it is not. The object remains outside consciousness in either case, and the image is the distinctive organization of consciousness that relates directly to it.

Schematic Images and the Organization of Seeing

Schematic drawings make the difference between an inner picture and an act of imaging especially clear. A few black lines can first be organized as simple geometrical features: three segments meet at a point, a second point lies below and to one side, and a curved line remains separate. Eye movements group the marks into forms against the white sheet; the lines need not yet be read as a face.

A change of intention can reorganize the same marks as a face. The segments become forehead, eyebrow, and nose; the isolated point becomes an eye, and the curved line a mouth and chin. That reading also alters the perceived space around the lines: the paper on one side functions as a filled, solid region, while the other side recedes as empty ground. The viewer’s eyes trace the features and supply a missing connection between separate groups of marks. Imaging therefore involves an active bodily and intentional synthesis, not the discovery of a tiny face already stored within consciousness.

This account also distinguishes a schematic image from perceptual figures that direct movement. In the Müller-Lyer illusion, the closed and open angles guide contrary eye movements, and those movements are projected onto the lines as properties: one segment seems to have greater power of extension. The lines become vectors, but the experience remains perceptual, not an image. In schematic imaging, by contrast, the figure does not itself impose a rule for movement. Knowledge directs the eye movements, which are experienced as spontaneous and projected onto the lines as imaged directions. If the image crystallizes, the viewer sees a running man in the marks while still recognizing the freely projected movements that make the figure legible.

Perception Without Mental Pictures

Rejecting the Immanence illusion also challenges the idea that images must be inserted into perception to explain why people perceive more than they strictly see. The real table and an imagined Pierre cannot simply combine as two contents within one consciousness: when the irreal Pierre surges up, the table leaves the scene, and the two objects belong to radically distinct acts. The image therefore cannot fill in perception by adding imagined qualities to sensory material.

A different explanation begins from the structure of perception itself. Edmund Husserl’s account describes perception as consciousness’s presence to a spatiotemporal object. That object is constituted not only by the aspect currently visible, but also by unformulated intentions concerning aspects that are absent—for instance, the unseen underside of an ashtray and its relation to the table. These intentions remain bound to the perceived object rather than becoming separate images. They enrich perception without turning its unseen aspects into inner pictures.

Research on formal structures offers another route for explaining why perception can exceed what is immediately visible. The persistence of forms through changes of position may account for certain stable features of perception. Such an explanation preserves the distinction between perceptual organization and imaging consciousness instead of treating an image as a hidden supplement inside the act of seeing.

Art and the Aesthetic Object

The distinction between a material support and an object given through imaging also clarifies Jean-Paul Sartre’s claim that the work of art is an irreality. In the portrait of Charles VIII, the canvas, frame, and layers of paint are real; the depicted Charles VIII, as the object of aesthetic appreciation, is not identical with those materials. He appears when consciousness takes an imaging attitude. Looking at the canvas as a real object and apprehending the depicted king are complete but exclusive acts, just as the same ambiguous drawing cannot be apprehended in two incompatible ways at once.

The painter does not transfer a private mental image into reality. The brushstrokes, the texture of the canvas, and the varnish are real, but they are not themselves the aesthetic object. They form a material Analogon through which a spectator can apprehend an image; they do not make its object real. A beam of light illuminates the canvas, not the depicted figure as an object of aesthetic appreciation. The painting is a material thing that is apprehended, in the imaging attitude, through the irreality it makes manifest.

This distinction separates sensory pleasure from aesthetic appreciation without denying that real colors can give pleasure. A red on a canvas may be sensually enjoyable, but in the painting it is apprehended as part of an irreal whole: for example, as the red of a wool rug beside a table. Its tactile and material character, and its relation to the colors and forms around it, contribute to the beauty of that represented whole. Even in cubist painting, the forms may be unfamiliar and need not imitate ordinary objects, yet they can be apprehended as things with density, matter, and depth. The painting still functions as an Analogon, manifesting an Irreal object rather than existing as the aesthetic object itself.

The same account extends to performance and fiction. An actor playing Hamlet uses the body, gestures, strength, and feelings as Analogons of the character’s conduct. The actor need not believe that he is Hamlet in the sense of taking the character as real; he may nevertheless be fully mobilized by the role. Even real tears can be apprehended by actor and audience as Hamlet’s tears. The character is not made real inside the actor; rather, the actor is irrealized in the character. Across portrait, stage, and other forms of art, the argument reverses the spatial picture behind the Immanence illusion: the aesthetic object is not a thing hidden inside its material support, but an object given through a distinctive act of consciousness.
