Abstract

On April 22, 1922, the Societé française de Philosophie hosted Albert Einstein for a discussion of the theory of relativity. In the course of this discussion, Henri Bergson, who was at that time writing Duration and Simultaneity, which explored some of the philosophical implications of Einstein's theory, was asked to share his thoughts. The resulting remarks offer a glimpse into Bergson's analysis of the concept of simultaneity, and Einstein's brief reply reveals his insistence that time itself, not just "the physicist's time," is relative.
