The usual activity of our mind is limited to the perception of the world around us, and its life, as far as the power of our senses reaches; it must, therefore, necessarily be confined within the limits of space and time. There are, however, specially favored men among us who profess an additional power, or even ordinary men may be thus endowed under peculiar circumstances, as when they are under the influence of nervous affections, trances, or even merely in an unusual state of excitement. Then they are no longer subject to the usual laws of distance in space, or remoteness in time; they perceive as immediately present what lies beyond the reach of others, and the magic power by which this is accomplished is called Divination. This vision is never quite clear, nor always complete or correct, for even such exceptionable powers are in all cases more or less subject to the imperfections of our nature; habitual notions, an ill-executed imagination, and often a disordered state of the system, all interfere with its perfect success. These imperfections, moreover, not only affect the value of such magic perceptions, but obscure the genuine features by a number of false statements and of erroneous impressions, which quite legitimately excite a strong prejudice against the whole subject. Hence, especially, the rigor of the Church against divination in every form; it has ever ascribed the errors mixed up with the true parts of such revelations to the direct influence of the Evil One. The difficulty, however, arises that such magic powers have nothing at all to do with the question of morality; the saint and the criminal may possess them alike, since they are elements of our common nature, hidden in the vast majority of cases, and coming into view and into life only in rare exceptional instances.
