‘Divination,’ saith Bacon, ‘is of two kinds—primitive, and by influxion.’ The former is founded on the belief that the soul, when by abstinence and observances it has been purified and concentrated, has ‘a certain extent and latitude of pre-notion.’ The latter is grounded on the persuasion that the foreknowledge of God and of spirits may be infused into the soul when rendered duly passive and mirror-like. Of these two kinds of divining the former is characterized by repose and quiet, the latter by a fervency and elevation such as the ancients styled _furor_. Now our mystical divines have this in common with the diviners, that they chiefly aim to withdraw the soul within itself. They may be divided most appropriately after a like manner. A cursory inspection will satisfy any one that theopathetic mysticism branches into two distinct, and often contrasted, species. There is the serene and contemplative mysticism; and over against it, the tempestuous and the active. The former is comparatively self-contained and intransitive; the latter, emphatically transitive. Its subject conceives himself mastered by a divine seizure. Emotions well-nigh past the strain of humanity, make the chest to heave, the frame to tremble; cast the man down, convulsed, upon the earth. Or visions that will not pass away, burn into his soul their glories and their terrors. Or words that will not be kept down, force an articulation, with quaking and with spasms, from organs no longer under his control. The contemplative mystic has most commonly loved best that side of Christian truth which is nearest to Platonism; the enthusiastic or practical mystic, that which connects it with Judaism. The former hopes to realize within himself the highest ascents of faith and hope—nay, haply, to surpass them, even while here below. The latter comes forth from his solitude, with warning, apocalyptic voice, to shake a sleeping Church. He has a word from the Lord that burns as a fire in his bones till it be spoken. He lifts up his voice, and cries, exhorting, commanding, or foretelling, with the authority of inspiration.
