so, from an immense reservoir of life, jets must be gushing out unceasingly, of which each, falling back, is a world. the evolution of living species within this world represents what subsists of the primitive direction of the original jet, and of an impulsion which continues itself in a direction the inverse of materiality. but let us not carry too far this comparison. it gives us but a feeble and even deceptive image of reality, for the crack, the jet of steam, the forming of the drops. are determined necessarily, whereas the creation of a world is a free act, and the life within the material world participates in this liberty.
