Most of the errors of philosophers have arisen from considering the human being in a point of view too detailed and circumscribed. He is not a moral, and an intellectual,--but also, and pre-eminently, an imaginative being. His own mind is his law; his own mind is all things to him. If we would arrive at any knowledge which should be serviceable from the practical conclusions to which it leads, we ought to consider the mind of man and the universe as the great whole on which to exercise our speculations. Here, above all, verbal disputes ought to be laid aside, though this has long been their chosen field of battle. It imports little to inquire whether thought be distinct from the objects of thought. The use of the words _external_ and _internal_, as applied to the establishment of this distinction, has been the symbol and the source of much dispute. This is merely an affair of words, and as the dispute deserves, to say, that when speaking of the objects of thought, we indeed only describe one of the forms of thought--or that, speaking of thought, we only apprehend one of the operations of the universal system of beings. IV.--CATALOGUE OF THE PHENOMENA OF DREAMS, AS CONNECTING SLEEPING AND WAKING. I. Let us reflect on our infancy, and give as faithfully as possible a relation of the events of sleep. And first I am bound to present a faithful picture of my own peculiar nature relatively to sleep. I do not doubt that were every individual to imitate me, it would be found that among many circumstances peculiar to their individual nature, a sufficiently general resemblance would be found to prove the connexion existing between those peculiarities and the most universal phenomena. I shall employ caution, indeed, as to the facts which I state, that they contain nothing false or exaggerated. But they contain no more than certain elucidations of my own nature; concerning the degree in which it resembles, or differs from, that of others, I am by no means accurately aware. It is sufficient, however, to caution the reader against drawing general inferences from particular instances. I omit the general instances of delusion in fever or delirium, as well as mere dreams considered in themselves. A delineation of this subject, however inexhaustible and interesting, is to be passed over. What is the connexion of sleeping and of waking? II. I distinctly remember dreaming three several times, between intervals of two or more years, the same precise dream. It was not so much what is ordinarily called a dream; the single image, unconnected with all other images, of a youth who was educated at the same school with myself, presented itself in sleep. Even now, after the lapse of many years, I can never hear the name of this youth, without the three places where I dreamed of him presenting themselves distinctly to my mind.
