Dark reflections from below all life

Habitually to dream magnificently, a man must have a constitutional determination to reverie. This in the first place; and even this, where it exists strongly, is too much liable to disturbance from the gathering agitation of our present English life. Already, what by the procession through fifty years of mighty revolutions amongst the kingdoms of the earth, what by the continual development of vast physical agencies,—steam in all its applications, light getting under harness as a slave for man, powers from heaven upon education and accelerations of the press, powers from hell (as it might seem, but these also celestial) coming round upon artillery and the forces of destruction,—the eye of the calmest observer is troubled; the brain is haunted as if by some jealousy of ghostly beings moving amongst us; and it becomes too evident that, unless this colossal pace of advance can be retarded (a thing not to be expected) [...] left to itself, the natural tendency of so chaotic a tumult must be to evil; for some minds to lunacy, for others a reagency of fleshly torpor. How much this fierce condition of eternal hurry upon an arena too exclusively human in its interests is likely to defeat the grandeur which is latent in all men, may be seen in the ordinary effect from living too constantly in varied company. The word dissipation, in one of its uses, expresses that effect; the action of thought and feeling is consciously dissipated and squandered. [...]

 

Among the powers in man which suffer by this too intense life of the social instincts, none suffers more than the power of dreaming. Let no man think this a trifle. The machinery for dreaming planted in the human brain was not planted for nothing. That faculty, in alliance with the mystery of darkness, is the one great tube through which man communicates with the shadowy. And the dreaming organ, in connexion with the heart, the eye, and the ear, compose the magnificent apparatus which forces the infinite into the chambers of the human brain, and throws dark reflections from eternities below all life upon the mirrors of the sleeping mind.
