Bergson distinguished between time as we actually experience it, lived time, that he called ‘real duration’ (durée réelle) and the mechanistic time of science: it consists of superimposing
spatial concepts into time. In addition, mechanistic time becomes a distorted version of the real thing. So time is perceived as a succession of separate, discrete, spatial constructs. We think we’re seeing a continuous flow of movement, but in reality what we’re seeing is a succession of fixed frames or stills.
