The Science of Human Nature: A Psychology for Beginners

by William Henry Pyle

(3) Habits of thought. There are certain habits of procedure in reasoning, apart from the association of the ideas. One can form the habit of putting certain questions to oneself when a problem is presented, so that certain types of relations are called up. If one is a scientist, one looks for causes. If one is a lawyer, one looks up the court decisions. If one is a physician, one looks for symptoms, etc.

One of the most important habits in connection with reasoning is the habit of caution. Reasoning is waiting, waiting for ideas to come that will be adequate for the situation. One must form the habit of waiting a reasonable length of time for associations to run their course. If one act too soon, before his organized experience has had time to pass in review, he may act improperly. Therefore one must be trained to a proper degree of caution. Of course, caution may be overdone. One must act sometime, one cannot wait always.

Another habit is that of testing out a conclusion before it is finally put into practice. It is often possible to put a conclusion to some sort of test before it is put to the real test, just as one makes a model and tries out an invention on a small scale. One should not have full confidence in a conclusion that is the result of reasoning, till the conclusion has been put to the final test of experiment, of trial.

This last statement leads us to the real function of reasoning. Reason points the way to action in a new situation. After the situation is repeated for a sufficient number of times, action passes into the realm of habit.

Language and Thinking. The fact that man has spoken and written language is of the greatest significance. It has already been pointed out that language is a means through which we can get experience secondhand. This proves to be a great advantage to man. But language gives us still another advantage. Without language, thinking is limited to the passing of sensory images that arise in accordance with the laws of association. But man can name things and the attributes of things, and these names become associated, so that thinking comes to be, in part at least, a matter of words. Thinking is talking to oneself. One cannot talk without language.

The importance that attaches to language can hardly be overestimated. When the child acquires the use of language, he has acquired the use of a tool, the importance of which to thinking is greater than that of any other tool. Now, one can think without language, in the sense that memory images come and go,—we have defined thinking as the flow of imagery, the passing or succession of ideas. But after we have named things, thinking, particularly reasoning, becomes largely verbal, or as we said above, talking to oneself.

Not only do we give names to concrete things but we give names to specific attributes and to relations. As we organize and analyze our experiences, there appear uniformities, principles, laws. To these we give names, such as white, black, red, weight, length, thickness, justice, truth, sin, crime, heat, cold, mortal, immortal, evolution, disintegration, love, hate, envy, jealousy, possible, impossible, probable, etc. We spoke above of meanings. To meanings we give names, so that a single word comes to stand for meanings broad and significant, the result of much experience. Such words as “evolution” and “gravitation,” single words though they are, represent a wide range of experiences and bring these experiences together and crystallize them into a single expression, which we use as a unit in our thought.

Language, therefore, makes thought easier and its accomplishment greater. After we have studied Cæsar for some years, the name comes to represent the epitome, the bird’s-eye view of a great man. A similar thing is true of our study of other men and movements and things. Single words come to represent a multitude of experiences. Then these words become associated and organized in accordance with the principles of association discussed above, so that it comes about that the older we are, the more we come to think in words, and the more these words represent. The older we are, the more abstract our thinking becomes, the more do our words come to stand for meanings and attributes and laws that have come out of the organization of our experience.

It is evident that the accuracy of our thinking depends upon these words standing for the truth, depends upon whether we have organized our experience in accordance with facts. If our word “Cæsar” does not stand for the real Cæsar, then all our thinking in which Cæsar enters will be incorrect. If our word “justice” does not stand for the real justice, then all our thinking in which justice enters will be incorrect.

This discussion points to the tremendous importance of the organization of experience. Truth is the agreement of our thought with the thing, with reality. We must therefore help the young to see the world clearly and to organize what they see in accordance with the facts and with a view to future use. Then the units of this organized experience are to be tagged, labeled, by means of words, and these words or labels become the vehicles of thought, and the outcome of the thinking depends on the validity of the organization of our experience.
