No one again need be misled by the artist's eager incursions into grounds of faith or principle; his design being merely to readjust all questions of such a kind by the light of art and law of imagination—to reduce all outlying provinces, and bring them under government of his own central empire—the "fourfold spiritual city" of his vision. Power of imaginative work and insight—"the Poetic Genius, as you now call it—"was in his mind, we shall soon have to see,"the first principle" of all things moral or material, "and all the others merely derivative;" a hazardous theory in its results and corollaries, but one which Blake at all events was always ready to push to its utmost consequences and defend at its extreme outworks. Against all pretensions on the part of science or experimental reasoning to assume this post he was especially given to rebel and recalcitrate. Whether or no he were actually prepared to fight science in earnest on its own pitched field—to dispute seriously the conquest of facts achieved by it—may be questionable; I for one am inclined to disbelieve this, and to refer much of his verbal pugnacity on such matters to the strong irregular humour, rough and loose as that of children, and the half simple half scornful love of paradox, which were ingrained in the man.
