Plotinus's Absolute, the First or One, might not be grasped by reason. Yet to approach and contemplate it was the best for man. Life's crown was the ecstasy of the supra-rational and supra-intelligible vision of it. This Plotinean irrationality was lofty; but it was too transcendent, too difficult, and too unrelated to the human heart, to satisfy other men. ...his followers would bring it down to the level of their irrational tendencies. ...There was a tendency to contrast the spiritual and real with the manifold of material nonentity, and a cognate tendency to emphasize the opposition between the spiritual and good, and the material and evil, or between opposing spiritual principles. With less metaphysical people such opposition would take more entrancing shapes in the battles of gods and demons. Probably it would cause ascetic repression of the physical passions. ...within the schools of Neo-Platonism, in the generations after Plotinus... these tendencies flourished, beneath the shelter of his elastic principles. Here three kindred currents made a resistless stream: a transcendental, fact-repelling dialectic; unveiled recognition of the supreme virtue of supra-rational convictions and experiences; and an asceticism which condemned matter and abhorred the things of sense. What more was needed to close the faculties of observation, befool the reason, and destroy knowledge in the end?
