Thus grows up a world of men, women, children, with their various hungers and needs. The Eternals try to provide for these needs by science and religion; but as they can build their science and religion only from their experience and observation of the contracted universe, the science is sand, and religion a web, and earth's wretched children remain under the cruel rule and curse of Urizen and his sons, calling his laws of Prudence the Eternal Laws of God.
_The Song of Los_ (engraved 1795) adds many interesting particulars of the process by which the world, with its philosophies and religions, has become what it is.
Los, the Eternal Prophet, is the father of all systems of thought, but it does not follow that all are equally true. For Los is out of the divine order, and therefore the systems inspired by him and his many sons, while containing streaks of the eternal truths, are all out of focus.
Thus Rintrah gave Abstract Philosophy to Brahma in the East, and it is defective because it is abstract. The same applies to all modern theosophical revivals of Hindoo religion. An abstraction for Blake was a falling away from concrete reality, and he found his deliverance in the Christian doctrine of God.
Palamabron, another son of Los, gave abstract Law to Trismegistus, Pythagoras, Socrates, and Plato. Abstract Law is also negative, and therefore Orc (passion) finds himself chained down with the chain of Jealousy, and howls in impotent rage.
Sotho teaches Odin a Code of War which at any time may become the philosophy of a nation.
All these, abstract philosophy, abstract law, the Mahometan Bible, Codes of War, with the Churches, Hospitals, Castles, Palaces, which they involve, while seeking to catch the joys of eternity, serve in reality to obliterate and erase eternity altogether, and the children of men schooled in these philosophies behold the vast of Nature shrunk before their shrunken eyes. After the shrinkage there can only arise a philosophy of the five senses, and then Newton and Locke, especially Locke, Rousseau and Voltaire, have it all their own way.
From all this Blake looked for deliverance to the thought-creating fires of Orc, which had flared up in France, and might be expected to spread over Europe, and set even Asia in a conflagration. The Kings of Asia, snug in their ancient woven dens, are startled into self-exertion, and emerging uneasily from their dens, call on kings, priests, counsellors and privy admonishers of men to use their immemorial rights to teach the Mortal Worms, and keep them in the paths of slavery. Happily, Orc's fires are insatiable. Raging in European darkness, he arose like a pillar of fire above the Alps, and, while "milk and blood and glandous wine in rivers rush," led the wild dance on mountain, dale, and plain, till the sullen earth shrunk away, and there dawned the eternal day.
