Plotinus’s scheme is thus indeed prompted by some of the deepest Mystical aspirations. But whilst in its one deliberate movement--that of man up to God--it starts from convictions and requirements that are deeply ethical, libertarian, spiritual, theistic: it will be shown, in its conception of the nature of the One and of this One’s relations down into the world, to be curiously naturalistic and determinist, and subtly materialistic. Thus does Greek Philosophy end in an impressively all-devouring Abstraction, in an intense Realism destructive, step by step, of precisely all that concrete, individual, personal Beauty, Truth, and Goodness, of all the spiritual, hence organic, interior, self-conscious reality, which had given occasion to this system. We have now but so many hypostatized abstractions, each more pale and empty than the other, each ever more simply a mere category of the human mind, indeed, but a category appropriate to Things and to Mathematico-Physical Laws, not to Spirit and to Ethico-Personal Organisms. The system, in its ultimate upshot and trend, is thus profoundly anti-Immanental, anti-Incarnational: a succession of increasingly exalted and increasingly empty Transcendences, each of which is, as it were, open upwards but closed downwards, takes the place of all deliberate operations and self-expressions of the Higher in and through the Lower, hence of all preveniences and condescensions of God. And in Proclus, practically the last non-Christian Greek Philosopher, all these intensely abstractive, naturalistic features get finally and fully systematized, whilst but intermittent traces remain of Plato’s richly manifold, organized activities and his at times strikingly incarnational conceptions; and only skeleton-schemes persist of those rapt recollective experiences of Plotinus which, derived in his case from direct experience, constitute him, among all Philosophers, as Dr. Edward Caird most aptly calls him, the “Mystic par excellence.” II. THE SECOND OF THE THREE FORCES: CHRISTIANITY, THE REVELATION OF PERSONALITY AND DEPTH. Now the whole of this clear, conceptual, abstractive Greek method, in as far as it identified abstractions with realities, and names with things, and reasoning with doing, suffering, and experience; and sought for Unity outside of Multiplicity, for Rest outside of Energizing, for the Highest outside of Personality and Character as these are developed and manifested in the permeation and elevation of the lower; has in so far been succeeded and superseded by two other great world-moving experiences of the human race, experiences apparently even more antagonistic to each other than either appears to be to the Greek view: Christianity and Scientific Method. 1. _The unique fulness and closeness of unity in multiplicity of our Lord’s life._
