Würzburg school

The Würzburg school enters Jean-Paul Sartre’s account as an experimental tradition for investigating thought through carefully directed introspection. Its importance lies less in a formal history or institutional description—the text supplies neither—than in the kinds of reports it makes available: fleeting, difficult-to-classify experiences through which thought can show its relation to images before a clear image has formed. These observations let Sartre challenge the assumption that thinking is either pure knowledge or a finished mental picture.

Identity and Method

Jean-Paul Sartre places the Würzburg school among the practitioners of experimental introspection, alongside Alfred Binet and other researchers. He treats its method as introspection conducted with a degree of rigour: subjects are asked to attend to what occurs in consciousness and to report it, rather than having the investigator infer an image merely from the task performed. The reports matter because mental imagery is difficult to observe directly. A fully formed image can be elusive, while the stages through which knowledge takes on sensible or quasi-sensible character may be brief and obscure.

The school’s evidence therefore serves as more than a catalogue of inner experiences. It gives Jean-Paul Sartre material for distinguishing kinds and degrees of consciousness. In the terminology discussed in the book, reports of pure knowledge can be described as consciousness of relations, rules, or intentions. But the experimental accounts also reveal states that are empty of determinate visual content while already directed toward sensible representation. Such cases trouble any simple division between an abstract thought and an image that arrives afterward as its illustration.

Reports on Knowledge and Emerging Images

The reports attributed to Würzburg psychologists include two different kinds of empty consciousness. In one, the stimulus is CIRCLE, and the subject reports a general consciousness corresponding to the concept of a geometrical figure, without the word itself being present. In the other, PATIENCE–FORBEARANCE gives rise to a particular consciousness situated in a biblical environment. The contrast suggests that what occurs in thought cannot be reduced to a verbal item: a subject may grasp a general conceptual direction or a contextually particular one without reporting a complete, perceptually detailed image.

Elsewhere, Jean-Paul Sartre considers experimental reports that sharpen the problem of how knowledge becomes image. A subject given the word open reports an indeterminate image of an opening; another, responding to dissimilar, reports two indeterminate objects that are nevertheless grasped as unlike. These examples are cited through Schwiete, not identified as reports from the Würzburg school alone. Their relevance to the school’s broader experimental setting is that they expose a middle ground: the subjects affirm an image, yet cannot specify a determinate shape or spatial feature that would explain the distinction through ordinary visual representation.

Jean-Paul Sartre uses this evidence to argue that knowledge entering into the constitution of an image is altered, rather than simply completed by an intuitive picture. There can be a preliminary state that remains empty but is already intimately related to the sensible and capable of developing toward visual representation. In his account, the reports thus support a graded passage from pure signification through imaging knowledge toward a more fully formed image, while also warning that subjects’ own uncertainty makes these states hard to classify decisively.

Bodily and Motor Reports

The experimental material also includes reports of movements and bodily attitudes accompanying intellectual and emotional activity. As relayed through Burloud, subjects describe attention moving from side to side, a symbolic sensation of nodding in assent, pressure in the jaw while turning away from a thought, and uncertainty registered in the hands or posture. The reports are notable precisely because subjects may not know whether they are describing an image, a sensation of movement, or an attitude of consciousness.

For Jean-Paul Sartre, that uncertainty is theoretically significant. It suggests that thinking need not be accompanied only by clear visual representations: obscure motor apprehensions may belong to the same unfolding process. He describes this region as a zone of semi-darkness, in which poorly differentiated pieces of imaging knowledge and symbolic apprehensions of movement pass quickly and resist inspection. When one such piece of knowledge becomes fixed on a movement, imaging consciousness can emerge. The bodily reports therefore help connect intellectual activity to the subtle movements and attitudes through which a thought is organized, without requiring that those movements already constitute a definite picture.

Place in Sartre’s Account of Thought

The school’s findings contribute to Jean-Paul Sartre’s rejection of the view that images are inert mental materials which thought later selects and arranges. The experimental reports instead make it possible to consider imaging knowledge, bodily tendencies, and image formation as related phases or structures within conscious activity. The image is not simply an illustration attached from outside to an otherwise complete thought; knowledge and intention may already be involved as an image develops.

The book also sets limits on what can be concluded from introspection. Subjects sometimes hesitate over whether an experience is an image or a thought, or whether a bodily occurrence belongs to consciousness of an attitude or to an attitude of consciousness. For Jean-Paul Sartre, this indeterminacy does not make the reports useless; it identifies the phenomenon that an overly sharp distinction would conceal. The Würzburg school’s importance in his argument is consequently evidential and methodological: its reported cases illuminate transitional and mixed forms of thought, helping him describe how consciousness can move toward imagery without treating the image as either a passive trace or a finished object supplied all at once.
