Blake invented names for them. Of these--Urizen, Urthona-Los, Luvah, and Tharmas--Urizen and Los are by far the clearest conceived figures. Perfect unity is maintained so long as Los is supreme. Reason is important in its right place. It becomes an evil when it usurps the place of imagination and thinks it can see as far. The essence of the fall is disorder. Redemption restores order, which is unity. Science alone breaks down because it is built up on observation and induction. Its observation is insufficient, for it is the observation of a shrunk universe. It gathers its materials through the five senses. But there are other avenues in regenerated man. If science were built up on the observation or vision of the whole instead of a very small part, it would become divine science and coincident with religion. Religion breaks down whether built on nature or experience. If on nature, it is nature only as seen through limited vision; if on experience, it is the experience of fallen man, and therefore it is of vital force only when it transcends nature and becomes super-natural, and rests on a revelation not from man's experience, however deep, but from God. [Illustration: ALBION. _From Jerusalem._] Deism was the particular time-heresy of Blake's day. He came into direct contact with it through his friend Tom Paine. Deistic religion, to be adequate for man's need, must rest on perfect nature and perfect experience. Paine, Voltaire, and Rousseau, in order to provide these conditions which they saw to be necessary, were driven to make the wild statement, contrary to all experience, that man is naturally holy and good, and if he is not so as we know him, it is because he is everywhere perverted by artificial civilization. Having swallowed this baseless assumption, the rest was easy. They had only like Godwin to manufacture some scheme of political justice, or like Rousseau to arrange a social contract, and then the Millennium would come.
