less intimate is the connection of psychology with the science of life. The physician finds in the practice of his profession, that in order to success, the laws of the human mind must constitute an important part of his study—how to avoid, and how to touch, the secret springs of human action. A word rightly spoken is often better than a medicine. In order to comprehend the nature of disease he must understand the effect on the bodily organization of the due, and also of the undue, exertion of each of the mental faculties; in fine, the whole relation of the mind to the bodily functions, and its influence over them—a field of inquiry as yet but imperfectly understood, if indeed adequately appreciated by the medical profession.

      As related to Oratory.—To the public speaker, whether at the bar, in the public assembly, in the halls of legislation, or in the pulpit, it need hardly be said that a knowledge of this science, and the ability to make practical use of it, is indispensable. Success in oratory depends, doubtless, in a measure, upon other things; but he who best understands the laws and operations of the human mind, how to touch the sensibilities, how to awaken the passions, how to excite the fears and the hopes, how to rouse the resentment of his hearers, how to soothe the troubled spirits, and allay the excitement of feeling, and disarm prejudice, and call into play the sober reason and calm judgment of man, will best be able to accomplish his purpose. He will be able to turn to his own account the circumstances of the occasion, and like a skillful organist, touch with ease, yet with precision and effect, what key he will. No man can do this who does not well understand the instrument.

      As related to the Art of Education.—Especially is this science of use to the teacher in the knowledge which it gives him of the mind of his pupil, and the skill in dealing with that mind. The mind of the pupil is to him the instrument on which he is required to play—a curious instrument of many and strange keys and stops—capable of being touched to wonderful harmony, and to fearful discord;—and to handle this instrument well is no ordinary acquirement. What shall we say of the man who knows nothing of the instrument, but only the music to be performed, nothing of the mind to be taught, but only the knowledge to be communicated? To know the mind that is to be taught, how to stimulate, how to control, how to encourage, how to restrain, how to guide and direct its every movement and impulse, is not this the very first and chief thing to be known?

      Connection of this Science with our own personal Interests.—The importance of mental science is evident not only from its relation to other sciences, but from the relation it sustains to man and his higher interests. Some sciences interest us as abstractions—merely speculative systems of truth; others as realities, but of such a nature, and so remote from the personal interests and wants of the race to which we belong, that they make little appeal to our sensibilities. Thus it is with mathematical and astronomical truth. The heavenly bodies, whose movements we observe, hold on their swift silent way, in the calmness of their own eternity, regardless of man and his destiny, even as they rolled ages ago, and as they will ages hence. What have we to do with them or they with us? We watch them as they hold their course through the deep firmament, as children, standing on the sea-side, watch the distant snowy sail that glides silently along the horizon, afar off, beautiful, unknown. So sail those swift ships of the firmament, and only he who made them knows their history.

      Psychology in contrast with other Sciences in this respect.—But when we come to the study of ourselves, and the laws of our own intelligence, our inquiries assume a practical importance which attaches to no other departments of truth. It is no longer the sail dimly visible on the far horizon, but our own conscious being that is the object of thought. The question no longer is, Whence comes that swift ship, and whither goes it, but, What am I, and whither going; what my history, and my destiny? This mysterious soul which animates me, and is the presiding divinity over all my actions, what is it, with all its wondrous faculties—sense, imagination, reason, will—those powers of my being? What is that change which passes upon me, which men call sleep, and that more mysterious and fearful change that must soon pass upon me, and that men call death? How is it that events of former years come back to mind, with all the freshness and reality of passing scenes? What is that principle of my nature that ever assumes to itself the right of command, saying to all my inclinations and passions, thou shalt, and thou shalt not, and when I disobey that mandate, filling my whole soul with misery, my whole future existence with remorse? And what and whence that word ought, that has so much to do with me and my pursuits: ought what, and why ought, and to whom?—Am I free, or am I subject to inevitable necessity; if free, then how are all my actions controlled, and predetermined by a divine Providence? If not free, then how am I responsible? Who shall solve this problem; who shall read me this strange inexplicable riddle of human life? Such are the questions and themes which mental philosophy discusses, and we perceive at a glance their intimate connection with the highest interests and personal wants of man as an individual.

      Connection of this Science with mental Discipline.—The importance of mental science may be further apparent in its effect on the culture and discipline of the mind. It is the peculiar effect of this science to sharpen and quicken the mental powers, to teach precision and exactness of thought and expression, to train the mind to habits of close attention and concentration of thought, to lead it to inquire into the causes and relations of things; in a word, to render it familiar with the great art of distinguishing things that differ. It would hardly be possible to name another branch of study that tends so directly to produce these results in the cultivation of the mind.

      ANALYSIS AND CLASSIFICATION OF THE MENTAL POWERS.

      Importance of such a preliminary Investigation.—It is of the highest importance, as we approach a science like the one before us, to obtain, if possible, at the outset, a clear and comprehensive view of the field about to be explored. It is desirable that the traveller, before entering a new country, should learn something respecting its extent, its political and geographical divisions, its manners, its laws, its history. Even more necessary is it, in entering upon a new science, to know its boundaries and divisions, to obtain a clear idea, at the very commencement of our inquiries, of the number, nature, extent, and arrangement of the subject we are about to investigate. Otherwise we shall be liable to confusion and error, shall not know where, at any moment, in the wide field of investigation, we may chance to be, or what relation the topic of our immediate inquiry holds to the whole science before us; as a ship on the ocean, without observation and reckoning, loses her latitude and longitude. We shall be liable to confound those distinctions which are of less, with those which are of more importance, and to mistake the relation which the several topics of inquiry bear to each other. Especially is this previous survey and comprehension of the subject essential in a science like this, where so much depends on the clearness and accuracy with which we distinguish differences often minute, and on the definiteness with which we mark off and lay out the several divisions of our work. A thorough analysis and classification of the various faculties of the mind is necessary, in the first place, before we enter upon the special investigation of any one of them. Such a classification must serve as our guide-book and chart in all further inquiries.

      Difficulty of such an Investigation.—The importance of such a preliminary investigation is scarcely greater than its difficulty. It would be easy, indeed, to mention, almost at random, a considerable number of mental operations, with whose names we are familiar; and a little thought would enable us to enlarge the list almost indefinitely. But such a list, even though it might chance to be complete, would be neither an analysis nor a classification of these several powers. It would neither teach us their relations to each other and to the whole, nor enable us to understand the precise nature and office of each faculty. We could not be sure that we had not included under a common name operations essentially different, or assigned distinct places and offices to powers essentially the same. Much depends, moreover, on the order in which we take up the several faculties.

      It is evident at a glance that to form a clear, correct, and comprehensive arrangement of the powers of the mind, is no slight undertaking. A complete understanding of the whole science of the mind is requisite. It is one of the last things which the student is prepared to undertake, yet one of the first which he requires to know. Unfortunately for the science, perhaps no topic in the whole circle of intellectual investigation has been more
