“The image teaches nothing”

“The image teaches nothing” names Jean-Paul Sartre’s principle of quasi-observation: an image cannot disclose new knowledge about its object, because the consciousness that forms the image already supplies what the image contains. The principle distinguishes imagining from learning by observation. An imagined object may be present to consciousness, but it does not stand before consciousness as an independent source of information; its apparent presence is constituted by the very act that means to apprehend it.

The Principle and Its Method

The claim belongs to Sartre’s phenomenological description of image-consciousness. To describe an image as image, he argues, consciousness must reflect on its own act: while imagining Pierre, consciousness is directed at Pierre, not at an inner picture as a separate thing. Only a second-order reflective act turns attention toward how Pierre is given and makes possible the judgement that an image is present. Sartre treats this reflective description as distinct from hypotheses about the image’s psychological nature: the former aims at certain data, while explanatory theories remain matters of probability.

That distinction matters to the principle’s force. Sartre is not asking whether an image can be vivid, elaborate, or useful in thought. He is asking what kind of consciousness it is and whether its object can inform consciousness in the way an independently encountered object or an externally articulated sign can. His answer rejects the picture of consciousness as a container holding miniature copies. The image is itself a complete consciousness directed toward an object, not a little object inside consciousness that can be inspected for additional facts.

Knowledge, Images, and Indeterminate Content

Sartre’s discussion of experimental introspection shows why the image cannot simply be equated with a clear sensory representation. A subject asked to consider the word mountain reported a wordless direction toward something determined that could be climbed. Sartre reads this not as an intuitive mountain encountered in miniature, but as a rule-like or relational awareness. In Karl Bühler’s classification, such pure knowledge can consist in consciousness of rules, relations, or intentions; for example, the blue in a painting may be thought of as the fourth primary colour without its sensible quality being the focus.

Other experimental reports blur the boundary between thought and image. In material discussed through Schwiete, one subject reported an indeterminate image of an opening, while another reported two indeterminate, dissimilar objects. The opening had no determinate form, and the two objects had no intuitive spatial features that could explain their difference. Yet the subjects described them as imaged. Sartre uses such cases to argue that knowledge entering into image-consciousness has already changed: there can be an empty awareness that is nevertheless oriented toward the sensible and capable of giving rise to a visual impression. These reports do not show that an image teaches its subject what the object is; they show that image-consciousness can be present even where its sensible content is sparse or indeterminate.

The distinction also qualifies the account of images as fulfilments of signification associated with Edmund Husserl. Sartre resists treating the image as an added intuitive element that fills an otherwise empty meaning. An image is itself a consciousness, and knowledge does not pass into it without alteration. The reported opening and dissimilar objects make the problem vivid: if an image can be affirmed where determinate intuitive qualities are missing, its contribution cannot be described simply as supplying a fuller sensory presentation to a prior piece of knowledge.

Quasi-Observation and the Contrast with Language

The principle’s clearest contrast is between an imagined phrase and a phrase expressed in language. Speaking or writing can prolong, complete, and specify thought. Language may return a proposition more clearly defined than the thought that was given to it, and can thereby teach the thinker something. Sartre attributes this effect to language’s externality: sounds and phrases have arrangements partly independent of consciousness, so their structure can resist an initially vague thought and make its implications available for inspection.

An imagined phrase lacks that resistance. It changes to suit the knowledge that constitutes it, rather than standing apart as an independently observable structure. For this reason, an imaged phrase is never a complete phrase in the same way an external verbal expression can be. Inner language must also be distinguished from image-consciousness: words experienced as written or heard in the mind may be accompanying visual or auditory images, but Sartre argues that inner language itself is motor rather than an image. The distinction is not between meaningful and meaningless experience; it is between a sign whose external structure can return thought in a more determinate form and an image whose content does not exceed the consciousness that forms it.

Comprehension and Symbolic Schemas

Sartre applies the principle to symbolic schemas, the spatial or moving forms that may arise during difficult acts of comprehension. Drawing on Flach’s observations, he notes that such representations can appear together with understanding and bring the solution or comprehension of a phrase. They are not produced simply by trying to summon an illustration: when a subject aims directly at an image, the result may be only what Flach calls an illustration of thought. A schema arises when the effort is directed toward understanding, and Flach’s reports associate schemas with work that is neither too easy nor resolved by memory alone.

Messer’s experiments further distinguish comprehension with an image from comprehension without one. Some understanding proceeds through words; some may be direct and wordless; and the same phrase can, at different times, be understood with or without schemas. Sartre therefore locates the difference not in the object being understood but in the antecedent structure and attitude of consciousness. When comprehension takes an imaging form, the schema presents the result of the effort in spatial form. It does not subsequently perform the work of understanding: comprehension is realized in and through the construction of the schema, and once that construction is complete, the image has no further lesson to impart.

This account also explains why an image may seem to assist understanding without being an independent instrument of discovery. To comprehend a word such as proletariat in an unreflective, object-directed mode is to constitute the corresponding thing before consciousness, as if it were present. The object appears spatially and as imaged, but is given as absent; the resulting relation is quasi-observation, not inspection of a real object. The image-object is the intentional correlate of the act of comprehension. Later thoughts may then appear to be reactions to a transcendent object observed before consciousness, although Sartre says they arise from the original act of comprehension and are altered by having been motivated by thought in its imaged form.

Scope and Significance

The principle does not deny that images are involved in thought or that symbolic schemas can present the outcome of an intellectual effort. It denies that the image, once constituted, adds an independent body of knowledge or clarifies its own basis. What may appear to be information delivered by the image belongs instead to the consciousness that forms it, or to the knowledge and effort that preceded its appearance. The image’s presence is therefore not evidence that consciousness has encountered a new, fully observable object.

By setting reflective description apart from explanatory hypothesis, and image-consciousness apart from the external resistance of language, Sartre makes “The image teaches nothing” a methodological as well as a psychological claim. It cautions against treating an image as a mental picture that can be read for facts, while accounting for the real role imagery can play in comprehension: consciousness may adopt an imaging structure, but the image does not do the understanding on its behalf.
