Certain characteristics of Mr Bergson's manner will be remarked throughout: his provisional effort of forgetfulness to recreate a new and untrammelled mind; his mixture of positive inquiry and bold invention; his stupendous reading; his vast pioneer work carried on with indefatigable patience; his constant correction by criticism, informed of the minutest details and swift to follow up each of them at every turn. With a problem which would at first have seemed secondary and incomplete, but which reappears as the subject deepens and is thereby metamorphosed, he connects his entire philosophy; and so well does he blend the whole and breathe upon it the breath of life that the final statement leaves the reader with an impression of sovereign ease.
