O DIAGRAMA COMO PERFORMANCE: INSCRIÇÃO, MÉTODO E RACIONALIDADE

Abstract

A diagram consists of a set of lines and other geometric shapes. From their particular entanglement on a planispheric surface comes a graphic inscription. It is therefore an image. It consists of a unique category of visual transcription, manual operation and intellectual agency; therefore, a visual artifact of unequivocal cognitive, pedagogical and epistemic appeal. By combining different languages and different types of knowledge in a mestizo and transdisciplinary figuration, the diagram establishes other ways of apprehending and interacting with the data of reality. It thus contributes both to the systematization of an abstract judgment and to its assimilation and understanding. The diagram, therefore, is a fabric. Mobile, dynamic, flexible. Just like thought. It is activity, adjustment and recording. It condenses in itself the empirical concreteness of an action, the creation of an object - the image, the scheme - with the immateriality of a projective, suppositional, prognostic reasoning. In our paper - based on the considerations of John Bender and Michael Marrinan, in "The Culture of Diagram" (2010) - we provide some of the definitions of the diagram, usually situated between art and science, emphasizing its multidimensional character, that is, not only as a) individual visual annotation but as b) methodological procedure, supported and guided by a c) particular model of rationality.

Keywords: diagrams, images, epistemic representations.
