Blake was wrong, too, in his efforts to shut off Memory. Of course he could not succeed. Every page of _Jerusalem_ shows that Memory was at work though shackled. Memory alone could have made it coherent and a luminous whole, as it had made _Paradise Lost_; but it was not free enough to keep its different scenes, often very beautiful, from flying far apart, and the imagination grows weary in trying to capture the complete picture. The one thing in these poems that we can positively affirm to be new is their symbolism, and that cannot be defended. Symbolism is beautiful only as it is universal, or can become so. It should be one language against many tongues. But Blake's is not even the tongue of a nation or a tribe. It is his own private invention, and, incidentally, uncouth, forbidding, unintelligible, and in actual fact a little insane. It is true that we can learn his symbolism after much labour; but a beautiful and catholic symbolism is the one thing that we have a right to understand, without learning, through the imagination, which Blake always affirmed to be divine. Blake could not afford to indulge these idiosyncrasies. Like all mystics, he found it difficult to adjust the inner things that were real to him to the outer that were but a shadow. Since most people find the outer things are the substantial reality, they are not only moving in a different world from that of the mystic, but they are puzzled to know when the letter of his statements is to be taken. Ezekiel says that he ate his meat baked with cow's dung; Blake, that Hayley, when he could not act upon his wife, hired a villain to bereave his life. We know sufficient of Blake's relation to Hayley to understand that Hayley's murderous purpose was towards Blake's spiritual life, not his corporeal, and that he tried to prevail on Blake through his wife. We may hope also that Ezekiel did not really eat "abominable flesh," or lie for a preposterously long time on his left side. We mention the mystic's hazy treatment of external actions, to explain Blake; but we hope the mystic of the future will be more considerate of what his words are likely to convey to others, and then clear them of all ambiguity. Blake should have guarded himself perpetually here, but was too proud or wilful to do so. Hence with his merging of inward and outward things, and using the same language for both, added to his private symbolism, what should have been his greatest poems have become submerged continents in which you may discover endless treasures only if you dare to dive, and can hold your breath under water. Let us dive for the sake of understanding the growth of Blake's mind. I will take _Milton_ separately, and _The Four Zoas_ and _Jerusalem_ together.
