Jean-Paul Sartre–René Descartes intellectual relationship

The Jean-Paul Sartre–René Descartes intellectual relationship in The Imaginary is chiefly a methodological one. Jean-Paul Sartre takes the certainty associated with René Descartes’s cogito as a secure point of departure: reflective awareness that one is having an image cannot be mistaken. But he does not stop at establishing that certainty. He turns reflection into a procedure for describing what an image is as an act of consciousness, then uses that analysis to consider imagination’s role in consciousness and the irreality of aesthetic objects.

The Cartesian Starting Point

The account links Jean-Paul Sartre’s idea of the concrete to René Descartes’s cogito. For Descartes, doubt about the world does not undo the certainty that the thinker exists while thinking. In Sartre’s approach, the corresponding certainty concerns reflective awareness: someone who becomes conscious, in reflection, of having an image cannot be mistaken about that fact. This certainty makes reflection a starting point for inquiry into the image, rather than a conclusion about the nature of the external world.

That distinction shapes what Sartre takes from the Cartesian model. Reflection can establish that an image is present to consciousness; the next task is to describe the distinctive character of that experience. Sartre therefore asks what occurs when someone has an image and what marks it as an image. The connection to Descartes supplies an epistemic foothold, while the inquiry proceeds through phenomenological description rather than relying on that foothold alone to explain the image.

Reflection as a Method

Sartre illustrates the method with the image of Pierre. When someone produces an image of Pierre, Pierre—not a little replica enclosed within the mind—is the object of the current consciousness. While that consciousness remains unchanged, it can be described in terms of the object as imaged, but not in terms of the image as image. To describe the latter requires a second act of consciousness: reflection turns attention from the object to the way it is given. That shift makes the judgment that one has an image possible.

This reflective judgment is not treated as an ineffable revelation. The experience presents marks or characteristics that allow reflection to recognize it as imaging consciousness. Sartre calls the immediately available content of this reflective act the essence of the image and assigns psychology the task of making that essence explicit. The Cartesian claim of certainty thus becomes a disciplined descriptive program: identify what reflection can establish before proposing an explanation of how images arise or what they are made of.

This order of inquiry also explains Sartre’s distinction between description and theory. Psychologists, he argues, often leave immediate knowledge implicit and instead construct hypotheses about the image’s nature. Such hypotheses have only the probability of scientific explanation, whereas reflective data are certain. A study of images must therefore separate describing what is immediately given from making inductive claims about its underlying nature. Sartre’s proposed procedure is to produce images, reflect on them, and classify their distinctive characteristics before turning to broader explanations.

From Certainty to the Structure of Consciousness

The method challenges the assumption that an image is an item contained inside consciousness. Sartre identifies this spatial picture as an illusion: consciousness is not a place populated by miniature copies, and the object of an image is not itself tucked inside the image. The reflective examination prompted by the Cartesian starting point therefore redirects analysis away from imagined inner contents and toward the consciousness that intends an object in a particular way.

The inquiry eventually opens onto a metaphysical question. If consciousness is capable of imagining, is that capacity merely a contingent addition, or does it belong to consciousness’s constitutive structure? Sartre frames the issue as whether consciousness could be wholly absorbed in intuitions of the real and never imagine, or whether positing consciousness already entails its capacity to imagine. In the account’s conclusion, imaging consciousness and consciousness of the world are reciprocal: the imaginary appears against the world, while apprehending the real as a world involves a surpassing toward the imaginary. Imagination is consequently presented not as an accidental mental faculty but as an essential condition of consciousness.

The Extension to Aesthetic Objects

Sartre carries this analysis from the certainty of reflective experience into aesthetics. His account of the portrait of Charles VIII distinguishes the real canvas, frame, and layers of paint from the aesthetic object apprehended through them. The depicted figure is not identical to the material painting, nor is it simply a real object hidden behind the paint. It appears when consciousness adopts an imaging attitude; the canvas functions as a material analogon through which the irreal object can be grasped.

This distinction rules out a simple passage from a private mental image to a realized artwork. The real elements are the brushstrokes, the texture of the canvas, and the varnish, but these are not, by themselves, the object of aesthetic appreciation. The artist arranges material tones so that an irreal synthetic whole can appear to a spectator who takes up the imaging attitude. The work remains materially real while the aesthetic object disclosed through it remains irreal; it is not converted into an ordinary perceived thing.

The same account helps explain why aesthetic appreciation is not reducible to sensory pleasure. A red patch considered by itself may give a purely sensory enjoyment, but in a painting its value belongs to the irreal whole—for example, when it is grasped as the red of a rug in relation to a table or to the green of a wall. The depicted object and its relations give the color its aesthetic sense. Aesthetic enjoyment is real as an experience, yet it serves to constitute and apprehend the imaginary object through the canvas rather than treating the pigment alone as the beautiful object.

Sartre extends the principle beyond painting. Fictional writing, poetry, and drama present irreal objects through verbal analogons; an actor’s body and gestures can likewise serve as analogons for Hamlet. The actor need not posit that he is Hamlet in order to be fully mobilized in producing the character: the role’s feelings and actions are presented through the actor’s own resources as irreal. The discussion of music begins from a related distinction between a performance as a dated event and the symphony listeners seek to hear across different performances. In the example, the same symphony can be heard under different conductors and by different orchestras, while errors of tempo can seem to betray it. These extensions show how Sartre’s inquiry moves from the certainty of reflective consciousness toward a broader account of objects that are apprehended through consciousness without becoming ordinary real objects.
