Innovation in science, innovation in psychoanalysis

The paper examines the category of innovation in the light of its relations to scientific procedures. It then observes the consequences of the current use of innovation for the conception of a speaking subject and the act he/she performs. It takes the complex course of the history of science using wide time units to demonstrate the important traces left by the progress of science in the past centuries. It then shows that despite seeming far from our day to day life, operations carried on with mathematics, and especially geometry, constitutes the intellectual structure in which we are involved. It concludes that innovation having become mandatory paradoxically wards off the very novelty responsible for bringing around the speaking subject.
