Practical will, I think, find that none of Bergson's explanations, burdened, as he says, with geo metry, and as we may say with matter, from the obsession of which he never seems to shake him self altogether free, are comparable in depth or lucidity with the present treatise. The spirit is described by Bergson as memory, and matter as a succession of images. How does the one communicate with the other? The formula of the self-creative life process seems hardly sufficient to explain this, for if with Bergson we conceive of life as a torrent, there must be some reason why it should ?ow rather in one channel than in another. But life is supposed to create and to absorb matter in its progress; and here we seem to have entered a vicious circle, for the intuition presupposes, it does not create its object. As regards the will, too, the Bergsonian theory of the Ego as rarely (sometimes never once in life) fully manifesting itself, and our minor actions as under the control of matter, seems to lead to a deterministic conception and to be at variance with the thesis of the self-creation of life.
