Time, instant and duration / Le Temps, instant et duree

For a long time, scientists and philosophers spoke in unison about one and the same time. Human time was integrated into the time of nature. Modern science has considerably modified this perspective. It now evokes a possible divorce of the time of physics and the time of psychology. Something has been broken. In this masterful book, Pierre Buser and Claude Debru return to the evolution of our conception of time, through the ages, but also the disciplines. While today's physics discusses a lot about the reversibility of time, psychology and neuroscience willingly turn to two other facets: the present moment and the perception of the immediate future, this ""sense of the future"" that can be identified with scientific rigor. It is therefore no longer a question of a single time. By creating his own time, man has ended up understanding its singularity in relation to a physical time itself multiplied and diversified. Is a reconciliation between these different, increasingly antagonistic times still possible today? Pierre Buser is professor emeritus of neuroscience at the Pierre-et-Marie-Curie University in Paris. He is notably the author of Cerveau de soi, Cerveau de l'autre and L'Inconscient aux mille visages. Claude Debru is professor of philosophy of science at the École normale supérieure. Both belong to the Academy of Sciences.
