"Plato could not accept a philosophy destitute of spiritual aspirations; the two were at one with him. For the old Grecian sage there was a single object of attainment: real knowledge. He considered those only to be genuine philosophers, or students of truth, who possess the knowledge of the really-existing, in opposition to the mere seeming; of the always-existing, in opposition to the transitory; and of that which exists permanently, in opposition to that which waxes, wanes, and is developed and destroyed alternately. "Beyond all finite existences and secondary causes, all laws, ideas, and principles, there is an INTELLIGENCE or MIND [nou'", nou, the spirit], the first principle of all principles, the Supreme Idea on which all other ideas are grounded; the Monarch and Lawgiver of the universe; the ultimate substance from which all things derive their being and essence, the first and efficient Cause of all the order, and harmony, and beauty, and excellency, and goodness, which pervades the universe — who is called, by way of preëminence and excellence, the Supreme Good, the God (ὁ qeò") 'the God over all' (ὁ epi pasi qeò")." (Cocker: "Christianity and Greek Philosophy," xi., p. 377.) He is not the truth nor the intelligence, but "the father of it." Though this eternal essence of things may not be perceptible by our physical senses, it may be apprehended by the mind of those who are not willfully obtuse. (Before the Veil, xi/xii)"
