Einstein obsessively searched for unity in the universe, believing that science could reveal its immutable laws and describe them in the simplest possible way? Bergson, in contrast, claimed that the ultimate mark of the universe was just the opposite: never-ending change. Philosophies that did not stress the fluctuating, contingent, and unpredictable nature of the universe--as well as the essential place of human consciousness in it and its central role in our knowledge of it--were, according to him, retrograde and unlearned. While Einstein searched for consistency and simplicity, Bergson focused on inconsistencies and complexities.
