Surely such a body was not merely natural, any more than any other nation, society, or scientific school, made up of men and of the spirits, thoughts, affections of men. It, like them, was surely spiritual; and could be only living and healthy, in as far as it was in harmony with certain spiritual, unseen, and everlasting laws of God; perhaps, as certain Alexandrian philosophers would have held, in as far as it was a pattern of that ideal constitution and polity after which man was created, the city of God which is eternal in the Heavens. If so, may we not suspect of this Alexandria that it was its own fault if it became a merely physical phenomenon; and that it stooped to become a part of nature, and took its place among the things which are born to die, only by breaking the law which God had appointed for it; so fulfilling, in its own case, St. Paul’s great words, that death entered into the world by sin, and that sin is the transgression of the law? Be that as it may, there must have been metaphysic enough to be learnt in that, or any city of three hundred thousand inhabitants, even though it had never contained lecture-room or philosopher’s chair, and had never heard the names of Aristotle and Plato. Metaphysic enough, indeed, to be learnt there, could we but enter into the heart of even the most brutish negro slave who ever was brought down the Nile out of the desert by Nubian merchants, to build piers and docks in whose commerce he did not share, temples whose worship he did not comprehend, libraries and theatres whose learning and civilisation were to him as much a sealed book as they were to his countryman, and fellow-slave, and only friend, the ape. There was metaphysic enough in him truly, and things eternal and immutable, though his dark-skinned descendants were three hundred years in discovering the fact, and in proving it satisfactorily to all mankind for ever. You must pardon me if I seem obscure; I cannot help looking at the question with a somewhat Alexandrian eye, and talking of the poor negro dock-worker as certain Alexandrian philosophers would have talked, of whom I shall have to speak hereafter. I should have been glad, therefore, had time permitted me, instead of confining myself strictly to what are now called “the physic and metaphysic schools” of Alexandria, to have tried as well as I could to make you understand how the whole vast phenomenon grew up, and supported a peculiar life of its own, for fifteen hundred years and more, and was felt to be the third, perhaps the second city of the known world, and one so important to the great world-tyrant, the Cæsar of Rome, that no Roman of distinction was ever sent there as prefect, but the Alexandrian national vanity and pride of race was allowed to the last to pet itself by having its tyrant chosen from its own people.
