are threatened with being transported out of the conventional world of Heaven, Hell, Chaos, and Paradise, to which we had well adapted ourselves, into the real world in which we know that such beings could not breathe and move. For the world of _Paradise Lost_ is an ideal, conventional world, quite as much as the world of the _Arabian Nights_, or the world of the chivalrous romance, or that of the pastoral novel. Not only dramatic, but all, poetry is founded on illusion. We must, though it be but for the moment, suppose it true. We must be transported out of the actual world into that world in which the given scene is laid. It is chiefly the business of the poet to effect this transportation, but the reader (or hearer) must aid. "Willst du Dichter ganz verstehen, musst in Dichter's Lande gehen." If the reader's imagination is not active enough to assist the poet, he must at least not resist him. When we are once inside the poet's heaven, our critical faculty may justly require that what takes place there shall be consistent with itself, with the laws of that fantastic world. But we may not begin by objecting that it is impossible that such a world should exist. If, in any age, the power of imagination is enfeebled, the reader becomes more unable to make this effort; he ceases to co-operate with the poet. Much of the criticism on _Paradise Lost_ which we meet with resolves itself into a refusal on the part of the critic, to make that initial abondonment to the conditions which the poet demands; a determination to insist that his heaven, peopled with deities, dominations, principalities, and powers, shall have the same material laws which govern our planetary system. It is not, as we often hear it said, that the critical faculty is unduly developed in the nineteenth century. It is that the imaginative faculty fails us; and when that is the case, criticism is powerless--it has no fundamental assumption upon which its judgments can proceed,
