Ce texte aborde la question de l’accès cognitif à la réalité phénoménologique à partir de la reconnaissance du jeu de trois invariants (l’incomplétude, l’autoréférence et l’indétermination) qui conditionnent notre rapport conscient au monde. La lecture ternaire ainsi proposée du processus d’observation consciente qu’engage la perception conduit à poser que toute perception est à la fois partielle, partiale et parcellaire. L’intelligibilité de la réalité s’inscrit alors dans un référentiel qui articule domaine de validité, champ d’intelligibilité et degré de résolution. En même temps, elle confronte la réflexion à la Relativité générale, à l’Humain et à l’Organisation comme constituants de la réalité phénoménologique et du regard pluri, inter et spécifiquement transdisciplinaire.

Perception as the founding component of knowledgeThis article deals with the issue of accessing phenomenological reality. “Accessing” is a founding concept of the paradigm of complexity and constructivism. Here, the perception phenomenon throws a new light on the issue of accessing. The first step is to recognize the presence of three constants at the heart of our conscious relationship to our environment at large : incompleteness, self-reference and indeterminacy. The proposition here is to approach the concept of perception under the ternary guideline of transdisciplinarity. This leads us to the observation that perception is definable within three forms of the concept of Limit : These are partial (in deficit), partial (biased) and partial (fragmented). The challenge is then to be able to launch a combination process of antagonistic relationships between the three binary pairs of poles consisting of partial (in deficit) with partial (biased), partial (biased) with partial (fragmented) and partial (fragmented) with partial (in deficit). This analysis bearing on ternary relations is called “trialectic”. It is by no means esoteric and we believe that it opens up a fruitful understanding for a pluri or trans disciplinary thinking. This approach allows for contradictions and antagonisms which are intrinsically part of a dynamic comprehension of reality. À trialectic analysis of perception reveals a close relationship to the development of knowledge and the phenomenology of reality as such. The intelligibility of reality emerges from a system of references combining dynamically three entities namely a sphere of validity, a field of intelligibility and a degree of resolution. Simultaneously, the trialectic approach will involve general relativity, the human entity and the principle of organization as basic constituents of the phenomenon of reality and of the transdisciplinary approach.
