This article offers an epistemological reflection on the representation of concepts through the "circept” tool, an innovative semiological mapping approach. After tracing the historical evolution of the concept notion in Western thought and exploring various attempts at visual representations of thinking, the study presents the circept as an original synthesis between creativity techniques and structural analysis. This method, which organizes the dimensions of a concept according to a circular structure, overcomes the limitations of traditional binary approaches while preserving the complexity of semantic relationships. Through several case studies, the article demonstrates the relevance of the circept as a heuristic tool for conceptual exploration, opening new perspectives for research in humanities and social sciences.
