rative sense-experience, is barren. It displays a world concealed under an adventitious show, a show of our own bodily production. The latter type is heavy with the contact of the things gone by, which lay their grip on our immediate selves. This latter type, the mode of causal efficacy, is the experience dominating the primitive living organisms, which have a sense for the fate from which they have emerged, and for the fate towards which they go—the organisms which advance and retreat but hardly differentiate any immediate display. It is a heavy, primitive experience. The former type, the presentational immediacy, is the superficial product of complexity, of subtlety; it halts at the present, and indulges in a manageable self-enjoyment derived from the immediacy of the show of things. Those periods in our lives—when the perception of the pressure from a world of things with characters in their own right, characters mysteriously moulding our own natures, become strongest—those periods are the product of a reversion to some primitive state. Such a reversion occurs when either some primitive functioning of the human organism is unusually heightened, or some considerable part of our habitual sense-perception is unusually enfeebled.
