A non-standard epistemology, relatively autonomous of the disciplines and of the present, is necessary to characterize a new logic of interdisciplinarity. This will show how the crisis of representation in science, contemporary changes in scientific object, heterogeneity and incompatibility of models (another narrative of the future in the sciences), leads us to practice an “interdiscipline” that cannot be characterized as a combination of different disciplinary knowledges. We will show how, within this heterogeneity, building “sites of interdiscipline” allows for new relations between the disciplines, including democratic relations between disciplines. This implies a translation or derivation from disciplines, and a concept of objects as “unknowns” and not represented at a “phenomenological distance”.
