Distinction of Consciousness and Self-Consciousness.—Others again distinguish between consciousness and self-consciousness; but all consciousness, properly so called, involves the idea of self or the subjective element. To know that I have a sensation is virtually to know myself as having it.
Cases of abnormal or suspended Consciousness.—In certain disordered and abnormal states of the nervous organism, the knowledge of what has transpired previously to that state seems to be lost; and then again, on passing out of that condition into the normal one, all knowledge of what took place while in the abnormal state is wanting. Instances are on record where persons have alternated in this manner from one to the other condition, carrying on, as it were, by turns, two separate and independent lines of mental activity. An instance of this nature is related by Dr. Wayland. It has been usual to speak of these as instances of disordered or suspended consciousness. Strictly speaking, however, it is not consciousness but memory that is in such cases disordered. It is not the knowledge of the present, but of the past, that is disturbed and deficient. While the abnormal state continues, the individual is conscious of what transpires in that state. When it ceases, the patient wakes as from a reverie or dream, and retains no recollection of any thing that took place during its continuance. It is the memory that fails, and not the consciousness. We are never conscious of the past.
Objects of Consciousness.—1. Consciousness deals only with reality. We are conscious only of that which is, not of that which may be. The poet is conscious indeed of his fiction, the builder of air-castles is conscious of his reverie, but the fiction and the reverie, regarded as mental acts, are realities, and it is only as mental acts that they are objects of consciousness.
2. Not every thing real is an object of consciousness, but only that which is present and in immediate relation to us. The destruction of Pompeii, and the existence of an Antarctic continent are realities, but not objects of my consciousness.
3. Primarily and directly we are conscious of our own mental states and operations; of whatever passes over the field of our mental vision, our thoughts, feelings, actions, physical sensations, moral sentiments and purposes: mediately and indirectly we are conscious of whatever, through the medium of sense, comes into direct relation to us. For instance, when I put forth my hand and it strikes this table, I am conscious not only of the movement, and the effort to move, but of the sensation of resistance also, and indirectly I may be said to be conscious not of the resistance only, but of something—to wit, the table—as resisting. This something I know, as really as I know the sensation and the fact of resistance. To this immediate perception of the external world in direct relation to our physical organism, Sir W. Hamilton would extend the sphere of consciousness. Usually, however, the term has been employed in a more restricted sense—to denote the knowledge of what passes within, rather than of what lies without the mind itself.
CHAPTER II.
ATTENTION.
General Character of this Power.—It has not been usual to treat of Attention as one of the distinct faculties of the mind. It is doubtless a power which the mind possesses, but like the power of conception, or more generally the power of thought and mental apprehension, it is involved in and underlies the exercise of all the specific mental faculties. Nor is it, like consciousness, confined to a distinct department of knowledge, viz., the knowledge of our own mental states. It is subsidiary to the other mental powers, rather than a faculty of original and independent knowledge. It originates nothing—teaches nothing—puts us in possession of no new truth—has no distinct field and province of its own. And yet without it other faculties would be of little avail.
Definitions.—If it were necessary to define a term so well understood, we might describe it as the power which the mind has of directing its thoughts, purposely and voluntarily, to some one object, to the exclusion of others. It is described by Dr. Wayland as a sort of voluntary consciousness, a condition of mind in which our consciousness is excited and directed by an act of the will. He speaks also of an involuntary attention, a state of mind in which our thoughts, without effort or purpose of our own, are engrossed by objects of an exciting nature. It may be questioned, perhaps, whether this is properly attention. Only in so far as attention is a voluntary act is it properly a power of the mind, and only in so far does it differ from the simple activity of thought, or of consciousness. The latter is always involuntary, and in this it differs from attention.
Instances in Illustration.—It can hardly be necessary to illustrate by example the nature of a faculty so constantly in exercise. Every one perceives, for instance, the difference between the careless perusal of an author—the eye passing listlessly over the pages, and the mind receiving little or no impression from its statements—and the reading of the same volume with fixed and careful attention, every word observed, every sentiment weighed, and the whole mental energy directed to the subject in hand. We pass, in the streets of a crowded and busy city, many persons whom we do not stop to observe, and of whose appearance we could afterward give no account whatever. Presently, some one in the crowd attracts our notice. We observe his appearance, we watch his movements, we notice his peculiarities of dress, gait, manners, etc., and are able afterward to describe them with some degree of minuteness. In the former case we perceive, but do not attend. In the latter, we attend, in order to perceive.
Sometimes the sole Occupation.—Attention seems to be at times the sole occupation of the mind for the moment, as when we have heard some sound that attracts our notice, and are listening for its repetition. In this case the other faculties are for the time held in suspense, and we are, as we say, all attention. The posture naturally assumed in such a case is that indicated by the etymology of the word, and may have suggested its use to designate this faculty, viz., attention—ad-tendo—a bending to, a stretching toward, the object of interest.
Analysis of the mental Process in Attention.—If we closely analyze the process of our minds in the exercise of this power, we shall find, I think, that it consists chiefly in this—the arresting and detaining the thoughts, excluding thus the exercise of other forms of mental activity, in consequence of which the mind is left free to direct its whole energy to the one object in view. The process may be compared to the operation of the detent in machinery, which checks the wheels that are in rapid motion, and gives opportunity for any desired change; while it may be compared, as regards the result of its action, to the helm that directs the motion of the ship, now this way, now that, as the helmsman wills.
Objects of Attention.—The objects of attention are of course as various as the objects of thought. Like consciousness, it may confine itself to our own mental states; and, unlike consciousness, it may comprehend also the entire range of objective reality. In the former case it is more commonly designated by the term reflection, in the latter, observation.
Importance of Habits of Attention.—The importance of habits of attention, of the due exercise and development of this faculty of the mind, is too obvious to require special comment. The power of controlling one's own mental activity, of directing it at will into whatever channels the occasion may demand, of excluding for this purpose all other and irrelevant ideas, and concentrating the energies of the mind on the one object of thought before it, is a power of the highest value, an attainment worth any effort, and which, in the different degrees in which it is possessed, goes far to make the difference between one mind and another in the realm of thought and intellectual greatness. While the attention is divided and the mind distracted among a variety of objects, it can apprehend nothing clearly and definitely; the rays are not brought to a focus, and the mental eye, instead of a clear and well-defined image, perceives nothing but a shadowy and confused outline. The mind while in this state acts to little purpose. It is shorn of its strength.
The power of commanding the attention and concentrating the mental energy upon a given object, is, however, a power not easily acquired nor always possessed. The difficulty of the attainment is hardly less than its importance. It can be made only by earnest effort, resolute purpose,
