The embarrassment that qualifies M. Bergson’s attainments in mathematics and physics has another and more personal source.  He understands, but he trembles.  Non-human immensities frighten him, as they did Pascal.  He suffers from cosmic agoraphobia.  We might think empty space an innocent harmless thing, a mere opportunity to move, which ought to be highly prized by all devotees of motion.  But M. Bergson is instinctively a mystic, and his philosophy deliberately discredits the existence of anything except in immediacy, that is, as an experience of the heart.  What he dreads in space is that the heart should be possessed by it, and transformed into it.  He dreads that the imagination should be fascinated by the homogeneous and static, hypnotised by geometry, and actually lost in Auseinandersein.  This would be a real death and petrifaction of consciousness, frozen into contemplation of a monotonous infinite void.  What is warm and desirable is rather the sense of variety and succession, as if all visions radiated from the occupied focus or hearth of the self.  The more concentration at this habitable point, with the more mental perspectives opening backwards and forwards through time, in a word, the more personal and historical the apparition, the better it would be.  Things must be reduced again to what they seem; it is vain and terrible to take them for what we find they are.  M. Bergson is at bottom an apologist for very old human prejudices, an apologist for animal illusion.  His whole labour is a plea for some vague but comfortable faith which he dreads to have stolen from him by the progress of art and knowledge.  There is a certain trepidation, a certain suppressed instinct to snap at and sting the hated oppressor, as if some desperate small being were at bay before a horrible monster.  M. Bergson is afraid of space, of mathematics, of necessity, and of eternity; he is afraid of the intellect and the possible discoveries of science; he is afraid of nothingness and death.  These fears may prevent him from being a philosopher in the old and noble sense of the word; but they sharpen his sense for many a psychological problem, and make him the spokesman of many an inarticulate soul.  Animal timidity and animal illusion are deep in the heart of all of us.  Practice may compel us to bow to the conventions of the intellect, as to those of polite society; but secretly, in our moments of immersion in ourselves, we may find them a great nuisance, even a vain nightmare.  Could we only listen undisturbed to the beat of protoplasm in our hearts, would not that oracle solve all the riddles of the universe, or at least avoid them?
