social
(b) A higher stage of curiosity develops under the influence of social stimuli. When the child learns that he can appeal to others to eke out his store of experiences, so that, if objects fail to respond interestingly to his experiments, he may call upon persons to provide interesting material, a new epoch sets in. "What is that?" "Why?" become the unfailing signs of a child's presence. At first this questioning is hardly more than a projection into social relations of the physical overflow which earlier kept the child pushing and pulling, opening and shutting. He asks in succession what holds up the house, what holds up the soil that holds the house, what holds up the earth that holds the soil; but his questions are not evidence of any genuine consciousness of rational connections. His why is not a demand for scientific explanation; the motive behind it is simply eagerness for a larger acquaintance with the mysterious world in which he is placed. The search is not for a law or principle, but only for a bigger fact. Yet there is more than a desire to accumulate just information or heap up disconnected items, although sometimes the interrogating habit threatens to degenerate into a mere disease of language. In the feeling, however dim, that the facts which directly meet the senses are not the whole story, that there is more behind them and more to come from them, lies the germ of intellectual curiosity.
(c) intellectual
(c) Curiosity rises above the organic and the social planes and becomes intellectual in the degree in which it is transformed into interest in problems provoked by the observation of things and the accumulation of material. When the question is not discharged by being asked of another, when the child continues to entertain it in his own mind and to be alert for whatever will help answer it, curiosity has become a positive intellectual force. To the open mind, nature and social experience are full of varied and subtle challenges to look further. If germinating powers are not used and cultivated at the right moment, they tend to be transitory, to die out, or to wane in intensity. This general law is peculiarly true of sensitiveness to what is uncertain and questionable; in a few people, intellectual curiosity is so insatiable that nothing will discourage it, but in most its edge is easily dulled and blunted. Bacon's saying that we must become as little children in order to enter the kingdom of science is at once a reminder of the open-minded and flexible wonder of childhood and of the ease with which this endowment is lost. Some lose it in indifference or carelessness; others in a frivolous flippancy; many escape these evils only to become incased in a hard dogmatism which is equally fatal to the spirit of wonder. Some are so taken up with routine as to be inaccessible to new facts and problems. Others retain curiosity only with reference to what concerns their personal advantage in their chosen career. With many, curiosity is arrested on the plane of interest in local gossip and in the fortunes of their neighbors; indeed, so usual is this result that very often the first association with the word curiosity is a prying inquisitiveness into other people's business. With respect then to curiosity, the teacher has usually more to learn than to teach. Rarely can he aspire to the office of kindling or even increasing it. His task is rather to keep alive the sacred spark of wonder and to fan the flame that already glows. His problem is to protect the spirit of inquiry, to keep it from becoming blasé from overexcitement, wooden from routine, fossilized through dogmatic instruction, or dissipated by random exercise upon trivial things.
§ 2. Suggestion
Out of the subject-matter, whether rich or scanty, important or trivial, of present experience issue suggestions, ideas, beliefs as to what is not yet given. The function of suggestion is not one that can be produced by teaching; while it may be modified for better or worse by conditions, it cannot be destroyed. Many a child has tried his best to see if he could not "stop thinking," but the flow of suggestions goes on in spite of our will, quite as surely as "our bodies feel, where'er they be, against or with our will." Primarily, naturally, it is not we who think, in any actively responsible sense; thinking is rather something that happens in us. Only so far as one has acquired control of the method in which the function of suggestion occurs and has accepted responsibility for its consequences, can one truthfully say, "I think so and so."
The dimensions of suggestion:
(a) ease
The function of suggestion has a variety of aspects (or dimensions as we may term them), varying in different persons, both in themselves and in their mode of combination. These dimensions are ease or promptness, extent or variety, and depth or persistence. (a) The common classification of persons into the dull and the bright is made primarily on the basis of the readiness or facility with which suggestions follow upon the presentation of objects and upon the happening of events. As the metaphor of dull and bright implies, some minds are impervious, or else they absorb passively. Everything presented is lost in a drab monotony that gives nothing back. But others reflect, or give back in varied lights, all that strikes upon them. The dull make no response; the bright flash back the fact with a changed quality. An inert or stupid mind requires a heavy jolt or an intense shock to move it to suggestion; the bright mind is quick, is alert to react with interpretation and suggestion of consequences to follow.
Yet the teacher is not entitled to assume stupidity or even dullness merely because of irresponsiveness to school subjects or to a lesson as presented by text-book or teacher. The pupil labeled hopeless may react in quick and lively fashion when the thing-in-hand seems to him worth while, as some out-of-school sport or social affair. Indeed, the school subject might move him, were it set in a different context and treated by a different method. A boy dull in geometry may prove quick enough when he takes up the subject in connection with manual training; the girl who seems inaccessible to historical facts may respond promptly when it is a question of judging the character and deeds of people of her acquaintance or of fiction. Barring physical defect or disease, slowness and dullness in all directions are comparatively rare.
(b) range
(b) Irrespective of the difference in persons as to the ease and promptness with which ideas respond to facts, there is a difference in the number or range of the suggestions that occur. We speak truly, in some cases, of the flood of suggestions; in others, there is but a slender trickle. Occasionally, slowness of outward response is due to a great variety of suggestions which check one another and lead to hesitation and suspense; while a lively and prompt suggestion may take such possession of the mind as to preclude the development of others. Too few suggestions indicate a dry and meager mental habit; when this is joined to great learning, there results a pedant or a Gradgrind. Such a person's mind rings hard; he is likely to bore others with mere bulk of information. He contrasts with the person whom we call ripe, juicy, and mellow.
A conclusion reached after consideration of a few alternatives may be formally correct, but it will not possess the fullness and richness of meaning of one arrived at after comparison of a greater variety of alternative suggestions. On the other hand, suggestions may be too numerous and too varied for the best interests of mental habit. So many suggestions may rise that the person is at a loss to select among them. He finds it difficult to reach any definite conclusion and wanders more or less helplessly among them. So much suggests itself pro and con, one thing leads on to another so naturally, that he finds it difficult to decide in practical affairs or to conclude in matters of theory. There is such a thing as too much thinking, as when action is paralyzed by the multiplicity of views suggested by a situation. Or again, the very number of suggestions may be hostile to tracing logical sequences among them, for it may tempt the mind away from the necessary but trying task of search for real connections, into the more congenial occupation of embroidering upon the given facts a tissue of agreeable fancies. The best mental habit involves a balance between paucity and redundancy of suggestions.
(c) profundity
(c) Depth. We distinguish between people not only upon the basis of their quickness and fertility of intellectual response, but also with respect to the plane upon which it occurs—the intrinsic quality of the response.
One man's thought is profound while another's is superficial; one goes to the roots of the matter, and another touches lightly its most external aspects. This phase of thinking is perhaps the most untaught of all, and the least amenable to external influence whether for improvement or harm. Nevertheless, the conditions of the pupil's contact with subject-matter
