Your Mind and How to Use It

Chapter VI


It is a common mistake that we _perceive_ everything that is reported to the mind by the senses. As a matter of fact we perceive but a very small portion of the reports of the senses. There are thousands of sights reported by our eyes, sounds reported by our ears, smells reported by our nostrils, and contacts reported by our nerves of touch, every day of our lives, but which are not _perceived_ or _observed_ by the mind. We perceive and observe only when the attention, reflex or voluntary, is directed to the report of the senses, and when the mind interprets the report. While perception depends upon the reports of the senses for its raw material, it depends entirely upon the application of the mind for its complete manifestation.

The student usually experiences great difficulty in distinguishing between _sensation_ and _perception_. A sensation is a simple report of the senses, which is received in consciousness. Perception is the _thought_ arising from the _feeling_ of the sensation. Perception usually combines several sensations into one thought or percept. By sensation the mind _feels_; by perception it _knows_ that it feels, and recognizes the object causing the sensation. Sensation merely brings a report from outside objects, while perception identifies the report with the object which caused it. Perception _interprets_ the reports of sensation. Sensation reports a flash of light from above; perception interprets the light as starlight, or moonlight, or sunlight, or as the flash of a meteor. Sensation reports a sharp, pricking, painful contact; perception interprets it as the prick of a pin. Sensation reports a red spot on a green background; perception interprets it as a berry on a bush.

Moreover, while we may perceive a simple single sensation, our perceptions are usually of a group of sensations. Perception is usually employed in grouping sensations and identifying them with the object or objects causing them. In its identification it draws upon whatever memory of past experiences the mind may possess. Memory, imagination, feeling, and thought are called into play, to some extent, in every clear perception. The infant has but feeble perception, but as it gains experience it begins to manifest perceptions and form percepts. Sensations resemble the letters of the alphabet, and perception the forming of words and sentences from the letters. Thus _c_, _a_, and _t_ symbolize sensations, while the word “cat,” formed from them, symbolizes the perception of the object.

It is held that all knowledge begins with sensation; that the mental history of the race or individual begins with its first sensation. But, while this is admitted, it must be remembered that sensation simply provides the simple, elementary, raw material of thought. The first process of _actual thought_, or knowledge, begins with perception. From our percepts all of our higher concepts and ideas are formed. Perception depends upon association of the sensation with other sensations previously experienced; it is based upon experience. The greater the experience, the greater is the possibility of perception, all else being equal.

When perception begins, the mind loses sight of the sensation in itself, for it identifies it as a quality of the thing producing it. The sensation of light is thought of as a quality of the star; the pricking sensation is thought of as a quality of the pin or chestnut bur; the sensation of odor is thought of as a quality of the rose. In the case of the rose, the several sensations of sight, touch, and smell, in their impression of the qualities of color, shape, softness, and perfume, are grouped together in the percept of the complete object of the flower.

A _percept_ is “that which is perceived; the object of the act of perception.” The percept, of course, is a mental state corresponding with its outside object. It is a combination of several sensations which are regarded as the qualities of the outside object, to which are combined the memories of past experiences, ideas, feelings, and thoughts. A percept, then, while the simplest form of thought, is seen to be a mental state. The formation of a percept consists of three gradual stages, viz.: (1) The attention forms definite conscious sensations from indefinite nervous reports; (2) the mind interprets these definite conscious sensations and attributes them to the outside object causing them; (3) the related sensations are grouped together, their unity perceived, and they are regarded as qualities of the outside object.

The plain distinction between a sensation and a percept may be fixed in the mind by remembering the following: _A sensation is a feeling_; _a percept is a simple thought identifying one or more sensations_. A sensation is merely the conscious recognition of an excitation of a nerve end; a percept results from a distinct mental process regarding the sensation.


It is of the utmost importance that we develop and train our powers of perception. For our education depends very materially upon our perceptive power. What matters it to us if the outside world be filled with manifold objects, if we do not perceive them to exist? Upon perception depends the material of our mental world. Many persons go through the world without perceiving even the most obvious facts. Their eyes and ears are perfect instruments, their nerves convey accurate reports, but the perceptive faculties of the mind fail to observe and interpret the report of the senses. They see and hear distinctly, but the reports of the senses are not observed or noted by them; they mean nothing to them. One may see many things, and yet _observe_ but few. It is not upon what we see or hear that our stock of knowledge depends, so much as it does upon what we perceive, notice, or observe.

Not only is one’s stock of practical knowledge largely based upon developed perception, but one’s success also depends materially upon the same faculties. In business and professional life the successful man is usually he who has developed perceptive powers; he who has learned to perceive, observe, and note. The man who perceives and takes mental notes of what occurs in his world is the man who is apt to know things when such knowledge is needed. In this age of “book education” we find that the young people are not nearly so observant as are those children who had to depend upon the powers of perception for their knowledge. The young Arab or Indian will observe more in an hour than the civilized child will in a day. To live in a world of books tends, in many cases, to weaken the powers of observation and perception.

Perception may be developed by practice. Begin by taking notice of the things seen and heard in your usual walks. Keep wide open the eyes of the mind. Notice the faces of people, their walk, their characteristics. Look for interesting and odd things, and you will see them. Do not go through life in a daydream, but keep a sharp lookout for things of interest and value. The most familiar things will repay you for the time and work of examining them in detail, and the practice gained by such tasks will prove valuable in your development of perception.

An authority remarks that very few persons, even those living in the country, know whether a cow’s ears are above, below, behind, or in front of her horns; nor whether cats descend trees head first or tail first. Very few persons can distinguish between the leaves of the various kinds of familiar trees in their neighborhood. Comparatively few persons are able to describe the house in which they live, at least beyond the most general features–the details are unknown.

Houdin, the French conjurer, was able to pass by a shop window and perceive every article in it, and then repeat what he had seen. But he acquired this skill only by constant and gradual practice. He himself decried his skill and claimed that it was as nothing compared to that of the fashionable woman who can pass another woman on the street and “take in” her entire attire, from head to foot, at one glance, and “be able to describe not only the fashion and quality of the stuffs, but also say if the lace be real or only machine made.” A former president of Yale is said to have been able to glance at a book and read a quarter of a page at one time.

Any study or occupation which requires _analysis_ will develop the power of perception. Consequently, if we will analyze the things we see, resolving them into their parts or elements, we will likewise develop the perceptive faculties. It is a good exercise to examine some small object and endeavor to discover as many separate points of perception as possible, noting them on a sheet of paper. The most familiar object, if carefully examined, will yield rich returns.

If two persons will enter into a contest of this kind, the spirit of rivalry and competition will quicken the powers of observation. Those who have had the patience and perseverance to systematically practice exercises of this kind, report that they notice a steady improvement from the very start. But even if one does not feel inclined to practice in this way, it will be found possible _to begin to take notice_ of the details of things one sees, the expression of persons’ faces, the details of their dress, their tone of voice, the quality of the goods we handle, and _the little things especially_. Perception, like attention, follows interest; but, likewise, interest may be created in things by observing their details, peculiarities, and characteristics.

The best knowledge gained by one is that resulting from his own personal perception. There is a nearness and trueness about that which one _knows_ in this way which is lacking in that which he merely _believes_ because he has read or heard it. One can make such knowledge a part of himself. Not only is one’s knowledge dependent upon what he perceives, but his very character also results from the character of his percepts. The influence of environment is great–and what is environment but things perceived about one? It is not so much what lies outside of one, as what part of it gets _inside_ of one by perception. By directing his attention to desirable objects, and perceiving as much of them as is possible, one really builds his own character at will.

The world needs good “perceivers” in all the walks of life. It finds a shortage of them, and is demanding them loudly, being willing to pay a good price for their services. The person who can voluntarily perceive and observe the details of any profession, business, or trade will go far in that vocation. The education of children should take the faculty of perception into active consideration. The kindergarten has taken some steps in this direction, but there is much more to be done.
