former is the space of the intellect, the latter is physical space? Sometimes they found it reconstructing the past, either by the power of retrospective vision, or by the mystery of a palingenesis not unlike the power a man might have of detecting in the form, integument, and embryo in a seed, the flowers of the past, and the numberless variations of their color, scent, and shape; and sometimes, again, it could be seen vaguely foreseeing the future, either by its apprehension of final causes, or by some phenomenon of physical presentiment. Other men, less poetically religious, cold, and argumentative--quacks perhaps, but enthusiasts in brain at least, if not in heart --recognizing some isolated examples of such phenomena, admitted their truth while refusing to consider them as radiating from a common centre. Each of these was, then, bent on constructing a science out of a simple fact. Hence arose demonology, judicial astrology, the black arts, in short, every form of divination founded on circumstances that were essentially transient, because they varied according to men's temperament, and to conditions that are still completely unknown. But from these errors of the learned, and from the ecclesiastical trials under which fell so many martyrs to their own powers, startling evidence was derived of the prodigious faculties at the command of the Being of Action, which, according to Lambert, can abstract itself completely from the Being of Reaction, bursting its envelope, and piercing walls by its potent vision; a phenomenon known to the Hindoos, as missionaries tell us, by the name of _Tokeiad_; or again, by another faculty, can grasp in the brain, in spite of its closest convolutions, the ideas which are formed or forming there, and the whole of past consciousness. "If apparitions are not impossible," said Lambert, "they must be due to a faculty of discerning the ideas which represent man in his purest essence, whose life, imperishable perhaps, escapes our grosser senses, though they may become perceptible to the inner being when it has reached a high degree of ecstasy, or a great perfection of vision." I know--though my remembrance is now vague--that Lambert, by following the results of Mind and Will step by step, after he had established their laws, accounted for a multitude of phenomena which, till then, had been regarded with reason as incomprehensible. Thus wizards, men possessed with second sight, and demoniacs of every degree--the victims of the Middle Ages--became the subject of explanations so natural, that their very simplicity often seemed to me the seal of their truth. The marvelous gifts which the Church of Rome, jealous of all mysteries, punished with the stake, were, in Louis' opinion, the result of certain affinities between the constituent elements of matter and those of mind, which proceed from the same source. The man holding a hazel rod when he found a spring of water was guided by some antipathy or sympathy of which he was unconscious; nothing but the eccentricity of these phenomena could have availed to give some of
