(2) _The organization of experience._ After experience comes its organization. This point has already been fully explained. It was pointed out that organization consists in thinking our experience over again in helpful relations. Here parents and teachers can be of very great service to children. (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.
