Inkblots as a cultural phenomenon: On the centenary of the Rorschach test

Approved or not, the Hermann Rorschach test can be considered more than just a test to a clinical trial. Reflection on it as a broader phenomenon may yield what is the most valuable: better knowledge of human nature. Objective This article aims to present the dual nature of Rorschach's inkblots: as a test of “guessing” the meaning of signs and as a test of perception. Method Narrative literature review on the meaning and interpretation of the Rorschach test. Results The nature and reception of inkblots. The inkblots have a dual nature: they require visual perception, and at the same time they are signs, whose meanings are extracted in the process of interpretation. This process is largely subject to cultural determinants; it also depends on the structure of stimuli and on their artistic expression. Charles Sanders Peirce's theory of signs and the sign nature of inkblots. According to Peirce, the interpretation of a sign, as a triadic structure, belongs to the ontic order and is a continuous process, taking place perpetually. Mental interpretation, as it were, follows the ontic dimension and constitutes a kind of reflection of this dimension. The phenomenology of perception and the interpretation of inkblots. Perception as viewed by Rorschach found its unintended, though strikingly consistent, complement in the philosophy of Maurice Merleau-Ponty. This is particularly clear in the acknowledgment of the role of the body in perception and in emphasis placed on the active and dynamic nature of the subject–object relationship. Rorschach and Merleau-Ponty vs. Peirce: similarities and differences. The seemingly completely different ways of understanding interpretation in Peirce's semiotics (indirect cognition) and in Merleau-Ponty's phenomenology (direct cognition), actually show important similarities. I draw attention to the ontic dimension of interpretation and its systemic character, which both philosophers stress, and to the view of interpretation as a perpetual process that is never completed, both in Peirce's semiotics and in Merleau-Ponty's phenomenology. Conclusion The semiotic and perceptual nature of the inkblots created by the Swiss psychiatrist reflects two basic and mutually complementary ways in which humans experience the world. This experience has both a psychological and an ontic nature, which makes it possible for an examination using the Rorschach test to become an encounter with an existential dimension.
