be constant factors in guiding association and, consequently, action. We wish to build up permanent attitudes toward truth, honesty, industry, sympathy, zeal, persistence, etc. It is evident that attitude is merely an aspect of habit. It is an habitual way of reacting to a definite and typical situation. This habitual way is strengthened by repetition, so that set or attitude finally, after years of repetition, becomes a part of our nature. Our prejudices become as strong, seemingly, as our instinctive tendencies. After a man has thought in a particular groove for years, it is about as sure that he will come to certain definite conclusions on matters in the line of his thought as that he would give typical instinctive or even reflex reactions. We know the direction association will take for a Presbyterian in religious matters, for a Democrat in political matters, with about as much certainty as we know what their actions will be in situations that evoke instinctive reactions.

Thinking and Reasoning. Thinking is the passing of ideas in the mind. This flow of ideas is in accordance with the laws of association above discussed. The order in which the ideas come is the order fixed by experience, the order as determined by the various factors above enumerated.

In early life, one’s mind is chiefly perceptual, it is what we see and hear and taste and smell. As one grows older his mind grows more and more ideational. With increasing age, a larger and larger percentage of our mental life is made up of ideas, of memories. The child lives in the present, in a world of perceptions. A man is not so much tied down to the present; he lives in memory and anticipation. He thinks more than does the child. A man is content to sit down in his chair and think for hours at a time, a child is not. This thinking is the passing of ideas, now one, then another and another. These ideas are the survivals or revivals of our past experience. The order of their coming depends on our past experience.

As I sit here and write, there surge up out of my past, ideas of creeks and rivers and hills, horses and cows and dogs, boys and girls, men and women, work and play, school days, friends,—an endless chain of ideas. This “flow” of ideas is often started by a perception. For illustration, I see a letter on the table, a letter from my brother. I then have a visual image of my brother. I think of him as I saw him last. I think of what he said. I think of his children, of his home, of his boyhood, and our early life together. Then I think of our mother and the old home, and so on and on. Presently I glance at a history among my books, and immediately think of Greece and Athens and the Acropolis, Plato, Aristotle, and Socrates, schoolmates and teachers, and friends connected in one way or another with my college study of Greek.

In this description of the process of thinking, I have repeatedly used the words “think of.” I might have said instead, “there came to mind ideas of Athens, ideas of friends,” etc. Thinking, then, is a general term for our idea-life.

Reasoning is a form of thinking. Reasoning, too, is a flow of ideas. But while reasoning is thinking, it is a special form of thinking; it is thinking to a purpose. In thinking as above described and illustrated, no immediate ends of the person are served; while in reasoning some end is always sought. In reasoning, the flow of ideas must reach some particular idea that will serve the need of the moment, the need of the problem at hand. Reasoning, then, is controlled thinking, thinking centering about a problem, about a situation that one must meet.

The statement that reasoning is controlled thinking needs some explanation, for the reader at once is likely to want to know what does the controlling. There is not some special faculty or power that does the controlling. The control is exercised by the set into which one is thrown by the situation which confronts one. The set puts certain nerve-tracts into readiness to conduct, or in other words, makes certain groups of ideas come into mind, and makes one satisfied only if the right ideas come. As long as ideas come that do not satisfy, the flow keeps on, taking one direction and then another, in accordance with the way our ideas have become organized. An idea finally comes that satisfies. We are then said to have reached a conclusion, to have made up our mind, to have solved our problem.

But the fact that we are satisfied is no sure sign that the problem is correctly solved. It means only that our past experiences, available at the time through association, say that the conclusion is right. Or, in more scientific terms, that the conclusion is in harmony with our past experience, as it has been organized and made available through association. There is not within us a little being, a reasoner, that sits and watches ideas file by and passes judgment upon them. The real judge is our nervous system with its organized bonds or connections.

An illustration may make the matter clearer: A boy walking along in the woods comes to a stream too wide for him to jump across. He wishes to be on the other side, so here is a situation that must be met, a problem that must be solved. A flow of ideas is started centering about the problem. The flow is entirely determined and directed by past experience and the present situation. The boy pauses, looks about, and sees on the bank a pole and several large stones. He has walked on poles and on fences, he therefore sees himself putting the pole across the stream and walking on it. This may be in actual visual imagery, or it may be in words. He may merely say, “I will put the pole across and walk on it.” But, before having time to do it, he may recall walking on poles that turned. He is not then satisfied with the pole idea. The perception of stones may next become clear in his mind, and if no inhibiting or hindering idea comes up, the stone idea carries him into action. He piles the stones into the stream and walks across.

As was mentioned above, the flow of ideas may take different forms. The imagery may take any form but is usually visual, auditory, motor, or verbal.

Further discussion of the point that reasoning is determined by past experience may be necessary. Suppose the teacher ask the class a number of different questions, moral, religious, political. Many different answers to the questions will be received, in some cases as many answers to the questions as there are pupils. Ask whether it is ever right to steal, whether it is ever right to lie, whether it is ever right to fight, whether it is ever right to disobey a parent or teacher, whether oak is stronger than maple, whether iron expands more when heated than does copper, whether one should always feed beggars, etc. The answers received, in each case, depend on the previous experience of the pupils. The more nearly alike the experiences of the pupils, the more nearly alike will be the answers. The more divergent the experiences, the more different will be the answers.

The basis of reasoning is ultimately the same sort of thing as the basis of habit. We have repeated experiences of the same kind. The ideas of these experiences become welded together in a definite way. Association between certain groups of ideas becomes well fixed. Later situations involving these groups of ideas set up definite trains of association. We come always to definite conclusions from the same situations provided that we are in the same mental set and the factors involved are the same.

Throughout early life we have definite moral and religious ideas presented to us. We come to think in definite ways about them or with them. It therefore comes about that every day we live, we are determining the way we shall in the future reason about things. We are each day getting the material for the solution of the problems that will be presented to us by future situations. And the reason that one of us will solve those problems in a different way from another is because of having somewhat different experiences, and of organizing them in a different way.

Meaning and the Organization of Ideas. In the preceding paragraphs we have several times spoken of the organization of ideas. Let us now see just what is meant by this expression. Intimately connected with the organization of ideas is meaning. What is the meaning of an idea? The meaning of an idea is another idea or group of ideas that are very closely associated with it. When there comes to mind an idea that has arisen out of repeated experience, there come almost immediately with it other ideas, perhaps vivid images which have been connected with the same experience. Suppose the idea is of a horse. If one were asked, “What is a horse?” ideas of a horse in familiar situations would present themselves. One may see in imagination a horse being driven, ridden, etc., and he would then answer, “Why, a horse is to ride,” or “A horse is to drive,” or “A horse is a domestic animal,” etc.

Again, “What is a cloud? What is the sun? What is a river? What is justice? What is love?” One says, “A cloud is that from which rain falls,” or “A cloud is partially condensed vapor. The sun is a round thing in the sky that shines by day. A river is water flowing along in a low place through the land. Justice is giving to people what they deserve. Love is that feeling one has for a person which makes him be kind to that person.” The answer that one gives depends on age and experience.

But it is evident that when a person is asked what a thing is or what is the meaning of a thing, he has at once ideas that have been most closely associated with the idea in question. Now, since the most important aspect of a thing is what we can do with it, what use it can be to us, usually meaning centers about use. A chair is to sit in, bread is to eat, water is to drink, clothes are to wear, a hat is a thing to be worn on one’s head, a shovel is to dig with, a car is to ride in, etc.

Use is not quite so evident in such cases as the following: “Who was Cæsar? Who was Homer? Who is Edison? What was the Inquisition? What were the Crusades?” However, one has, in these cases, very closely associated ideas, and these ideas do center about what we have done with these men and events in our thinking. “Cæsar was a warrior. Homer was a writer of epics. Edison is an inventor,” etc. These men and events have been presented to us in various situations as standing for various things in the history of the world. And when we think of them, we at once think of what they did, the place they fill in the world. This constitutes their meaning.

It is evident that an idea may have many meanings. And the meaning that may come to us at any particular moment depends upon the situation. A chair, for example, in one situation, may come to mind as a thing to sit in; in another situation, as a thing to stand in the corner and look pretty; in another, a thing
