Did the “smile” of Tasso at the close of this extraordinary scene, and the words which he omitted to add, signify that his friend had seen and heard more, perhaps, than the poet would have liked to explain? Did he mean that he himself alone had been seen and heard, and was author of the whole dialogue? Perhaps he did; for credulity itself can impose;—can take pleasure in seeing others as credulous as itself. On the other hand, enough has become known in our days of the phenomena of morbid perception, to render Tasso’s actual belief in such visions not at all surprising. It is not uncommon for the sanest people of delicate organisation to see faces before them while going to sleep, sometimes in fantastical succession. A stronger exercise of this disposition in temperaments more delicate will enlarge the face to figure; and there can be no question that an imagination so heated as Tasso’s, so full of the speculations of the later Platonists, and accompanied by a state of body so “nervous,” and a will so bent on its fancies, might embody whatever he chose to behold. The dialogue he could as easily read in the vision’s looks, whether he heard it or not with ears. If Nicholay, the Prussian bookseller, who saw crowds of spiritual people go through his rooms, had been a poet, and possessed of as wilful an imagination as Tasso, he might have gifted them all with speaking countenances as easily as with coats and waistcoats. Swedenborg founded a religion on this morbid faculty; and the Catholics worship a hundred stories of the like sort in the Lives of the Saints, many of which are equally true and false; false in reality, though true in supposition. Luther himself wrote and studied till he saw the Devil; only the great reformer retained enough of his naturally sturdy health and judgment to throw an inkstand at Satan’s head,—a thing that philosophy has been doing ever since.
