It is at its best when explaining its own thesis regarding the multiple rhythms of duration that are part of the material world, as Bergson sees it. It also excels when it is updating Bergsonian ideas with clearly cognate positions in ‘contemporary’ physics, biology, neurology, etc: it is then that it performs its objective optimally, namely to show that Bergson’s intuition of duration ‘can form the basis of new sciences or the rejuvenation of old ones.’
