In Hegel's view hypnotic phenomena produce a kind of temporary and artificial atavism. Mechanical or chemical means, or morbid conditions of body, may cause even for the intelligent adult a relapse into states of mind closely resembling those exhibited by the primitive or the infantile sensibility. The intelligent personality, where powers are bound up with limitations and operate through a chain of means and ends, is reduced to its primitively undifferentiated condition. Not that it is restored to its infantile simplicity; but that all subsequent acquirements operate only as a concentrated individuality, or mass of will and character, released from the control of the self-possessed mind, and invested (by the latter's withdrawal) with a new quasi-personality of their own. With the loss of the world of outward things, there may go, it is supposed, a clearer perception of the inward and particularly of the organic life. The Soul contains the form of unity which other experiences had impressed upon it: but this form avails in its subterranean existence where it creates a sort of inner self. And this inner self is no longer, like the embodied self of ordinary consciousness, an intelligence served by organs, and proceeding by induction and inference. Its knowledge is not mediated or carried along specific channels: it does not build up, piecemeal, by successive steps of synthesis and analysis, by gradual idealisation, the organised totality of its intellectual world. The somnambulist and the clairvoyant see without eyes, and carry their vision directly into regions where the waking consciousness of orderly intelligence cannot enter. But that region is not the world of our higher ideas,--of art, religion, and philosophy. It is still the sensitivity--that realm of sensitivity which is ordinarily covered by unconsciousness. Such sensitive clairvoyants may, as it were, hear themselves growing; they may discern the hidden quivers and pulses of blood and tissue, the seats of secret pain and all the unrevealed workings in the dark chambers of the flesh. But always their vision seems confined to that region, and will fall short of the world of light and ideal truth. It is towards the nature-bond of sensitive solidarity with earth, and flowers, and trees, the life that "rolls through all things," not towards the spiritual unity which broods over the world and "impels all thinking things," that these immersions in the selfless universe lead us.
