The One cannot, properly speaking, be an object of knowledge, but is apprehended by something higher than knowledge. This is why Plato calls it ineffable and indescribable. What we can describe is the way to the view, not the view itself. The soul which has never been irradiated with the light of that supreme splendour, nor filled with the passionate joy of a lover finding rest in the contemplation of his beloved, cannot be given that experience in words. But the beatific vision is open to all. He from whom it is hidden has only himself to blame. Let him break away from the restraints of sense and place himself under the guidance of philosophy, that philosophy which leads from matter to spirit, from soul to Nous, from Nous to the One. Plotinus himself, we are told, reached the climax of complete unification several times in his life, Porphyry only once, in the sixty-eighth year of his age. Probably the condition so denominated was a species of hypnotic trance. Its importance in the Neo-Platonic system has been considerably exaggerated, and on the strength of this single point some critics have summarily disposed of Plotinus and his whole school as unreasoning mystics. Mysticism is a vague word capable of very various applications. In the present instance, we presume that it is used to express a belief in the existence of some method for the discovery of truth apart from tradition; observation, and reasoning. And, taken in this sense, the Neo-Platonic method of arriving at a full apprehension of the One would be considered an extreme instance of mysticism. We must bear in mind, however, that Plotinus arrives at an intellectual conception of absolute unity by the most strictly logical process. It makes no difference that his reasoning is unsound, for the same criticism applies to other philosophers who have never been accused of mysticism. It may be said that after leading us up to a certain point, reason is replaced by intuition. Rather, what the ultimate intuition does is not to take the place of logic, but to substitute a living realisation for an abstract and negative conception. Moreover, the intuition is won not by forsaking logic, but by straining its resources to the very utmost. Again, one great characteristic of mysticism, as ordinarily understood, is to deny the truth of common observation and reasoning. Now Plotinus never goes this length. As we have already remarked, he does not even share Plato’s distrust of sensible impressions, but rather follows the example of Aristotle in recognising their validity within a certain sphere. Nor does he mention having received any revelations of divine truth during his intercourse with the absolute One. This alone marks an immense difference between his ecstasies—if such they can be called—and those of the Christian mystics with whom he is associated by M. Barthélemy Saint-Hilaire.[464]
