'Palgrave Macmillan is to be congratulated for reissuing these classic Bergson texts. This is a timely decision since Bergson was the great thinker of life and it seems, nearly one hundred years later, that we find ourselves once again required to conceive life. Keith Ansell Pearson and John Mullarkey have been at the forefront of the new conception of life, therefore no better editors for these volumes could be selected.' - Professor Leonard Lawlor, Department of Philosophy, University of Memphis, USA

'Long absent from the center of discussion in Western philosophy, Bergson has recently made a reappearance. The Centennial Series of his works undertaken by Palgrave Macmillan thus comes at an opportune time, making it possible for those interested in Bergson's ideas t have access to newly annotated versions of several of his chief writings, freshly introduced and discussed. It is particularly good to see the republication of Mind-Energy, a treasure trove of Bergsonian insights long out of print.' - Professor Pete A.Y. Gunter, Department of Philosophy and Religious Studies, University of North Texas, USA
