These same ideas—the transcendence of God, the existence of mediary powers between God and the world, the ascetic life as a means of growth, the dependence of man on God’s grace for his salvation, the possibility of the Beatific Vision—all are common in varying degrees to all the mystic philosophies of the day. In the third century Neoplatonism became the most popular and influential. Through Origen and St. Augustine it passed into Christian theology. The real problem for Neoplatonism, as for the other religious philosophies of this time, was to set forth the way by which the soul of man could grasp the Divine directly and find its happiness and complete satisfaction in perfect unity with him. We have just seen how Philo had conceived of God as wholly transcendent, and had established the logos as the mediator who furnishes the necessary connection between the eternal, transcendent God and the created, temporal world. Plotinus outdid Philo in that he removed his God one stage still farther away. His definition of God is necessarily similar to that of Philo, but he endeavors to give a notion of an Absolute more remote, if possible, than that of his predecessors. God he says is neither reason itself nor can he be grasped by the use of reason, but is above all knowledge and reason.[249] We must conceive of him as absolute unity, as at once pure creative activity, the first cause, the power on which the world depends, and at the same time as the final cause toward which the world is tending. The acts of creation are constant; yet God does not create the visible world directly, but as the sun without effort or loss to itself sends out its rays, so God out of the fullness of his perfection emanates Intelligence (Νοῦς), in which are immanent the Ideas: these are the causes of all things which come into being. The second grade of emanation is that of the World-soul (Ψυχή), which pours itself out, so to speak, into the individual souls. The last stage of emanation is that of Matter, the material which in itself has no characteristics of being. The sensible world is produced by the action of the Ideas on Matter, forming and shaping it through Intelligence.[250] You will note here the four stages, God, Intelligence, Soul, and Matter, as compared with Philo’s three, God, the Logos, and Matter.
