Course description This seminar is concerned with redefining the relationship of the future within the domains of philosophy, arts, and sciences. We will study how the future is not only a temporal lapse, supposed to occur after the past and the present, but above all a modality capable of intervening in the present. If the perspective of our future no longer depends on forthcoming developments of the present, then we will acquire a more intimate knowledge of the unknown that will introduce changes in our present. Invention is implicitly motivated by the call of the future. But this is an imagined future, inchoative, with snatches and sketches of images, time and places; a general idea that motivates invention. These fragments of the future, partly unknown and never completely given, are what allows one to inhabit space and time, and to find its individuation among others: The future that often gives rise to apocalyptic or science-fiction narratives is one already determined and received from the outside. However, the kind of future that stimulates invention is not engaged with existing narratives, but with the diversity of modes of invention of the disciplines themselves, as well as of the imagination and fiction peculiar to them. Invention cannot be separated from the future, but this is a future that resists narration, and which, from this point of view, contains a driving charge of silence. The seminar is both a review of existing literature regarding the connections between philosophy, arts, sciences, the future, and fiction: a forum for generating new associations between the realms. Throughout the seminar, students will work individually and collaboratively to work on practical exercises concerning the following: Consideration of the future does not depend on any discipline and it can be apprehended by each. We propose exercises of philosophical invention, of which we will give elements of methods, from future developed by the students according to their discipline of origin and/or their activity.
