"It is possible to suppose," says James, "that a God could, without impairing his activity, simultaneously behold all the minutest portions of the world. But if our human attention should be thus dissipated, we should merely contemplate all things vacuously, without ever finding occasion to do any particular act."
It is one of the marvelous phenomena of life that it is impossible to realize anything, without determining limits; that mysterious law which ordains that every living being has its "form" and "stature," unlike the minerals, which are indefinite in form and dimensions, is repeated in the psychical life. Its development, its auto-creation, is nothing but a determination even more precise, a progressive "concentration"; it is thus that from the primitive chaos our internal characteristic form is gradually shaped and chiselled.
The capacity for forming a conception of a thing, for judging and reasoning, has always this foundation. When, after having noted the usual qualities of a column, we abstract the general truth that the column is a support, this synthetic idea is based upon a selected quality. Thus in the judgment we may pronounce: columns are cylindrical, we have abstracted one quality from among the many others we could have adduced, as, columns are cold, they are hard, they are a composition of carbonate of lime, etc. It is only the capacity for such a selection which makes reasoning possible. When, for example, in the demonstration of the theorem of Pythagoras, children handle the various pieces of the metal insets, they should start from the point at which they become aware that a rectangle is equal to the rhomb, and a square is equal to the same rhomb. It is the perception of this truth which makes it possible to go on to the following reasoning: therefore the square and the rectangle are equal to each other. If it had not been possible to determine this attribute, the mind could not have arrived at any conclusion. The mind has succeeded in discovering an attribute common to two dissimilar figures; and it is this discovery which may lead to a series of conclusions by means of which the theorem of Pythagoras will be finally demonstrated.
Now, as in the case of will, decision presupposes a methodical exercise of the impulsive and inhibitory forces, only to be performed by the individual himself, until habits have been established, so in case of the intelligence, the individual must exercise himself in his activities of association and selection, guided and aided by external means, until he has developed, by the definitive elimination of certain ideas and the choice of others, "mental habits" characteristic of the individual, characteristic of the "type." Because, underlying all the internal activities the mind can construct, there is, as the phenomena of attention show us, the individual tendency, the "nature."
There is, undoubtedly, a fundamental difference between understanding and learning the reasoning of others, and being able "to reason," between learning how an artist may see the external world according to his prevailing interest in color, harmony, and form, and actually seeing the external world about a fulcrum which sustains one's own æsthetical creation. In the mind of one who "learns the things of others" we may find, as in a sack of old clothes hanging over the shoulders of a hawker, solutions of the problems of Euclid, together with the images of Raphael's works, ideas of history and geography, and rules of style, huddled together with a like indifference and a like sensation of "weight." While, on the other hand, he who uses all these things for his own life, is like the person who is assisted in attaining his own welfare, his own relief, his own comfort by those same objects which are merely burdens when in the sack of the hawker. Such objects are, however, no longer huddled together without order and without purpose in a closed bag, but set out in the spacious rooms of a well-ordered house. The mind which constructs may contain a great deal more than that mind in which pieces of knowledge are heaped up as in the bag; and in that mind, as in the house, the objects are clearly divided one from another, harmoniously arranged, and distinctive in their uses.
Between "understanding" because another person seeks to impress upon us the explanation of a thing by speech, and "understanding" the thing of ourselves, there is an immeasurable distance; the two are comparable to the impression made in soft wax, which will subsequently be effaced and replaced by other impressions, and the form chiselled in the marble by an artist, as his creation. He who understands of himself has an unforeseen impression; he feels that his consciousness has been liberated, and something luminous shines forth within him. Understanding, then, is not a matter of indifference; it is the beginning of something; sometimes it is the beginning of a life which renews itself within us. Perhaps no emotion is more fruitful for man than the intellectual emotion. He who makes a discovery rich in results certainly enjoys the greatest of human felicities; but even he who merely "understands" gets a lofty enjoyment which will rise superior to and overcome the most acute suffering. Indeed, he who is oppressed by a misfortune, if he can be brought to differentiate his own case from that of another, or to see a reason for his affliction, experiences relief, and a "sense of salvation." Amidst the confused darkness in which he was plunged, a consoling ray of intellectual light has reached him. The difficult matter, indeed, is to find the way of escape in the hour of darkness. When we reflect that a dog may die of grief on the grave of his master, and that a mother can survive on the grave of her only son, we see at once that it is the light of reason which makes the difference between the two. The dog cannot reason on the matter; it may die because no light can penetrate the darkness of its intelligence to overcome the depression of its grief.
But the thought of a universal justice, the living memory of the lost one which remains to us, saves the human being. And by degrees, not forgetfulness, which alone can save the animal, but the connection which the intelligence establishes with the universe, restores calm to the suffering soul. Such comfort could never be derived from the dry lesson of a professor, from memorizing the theory of a savant who is not in sympathy with the state of our soul. When we say, "to give ourselves a reason," "to derive strength from a principle," we imply that the ever-inquiring intelligence should be left at liberty to perform its work of reconstruction and salvation.
Now if intelligence in "comprehending" may actually prove our salvation when in danger of death, what a source of enjoyment it should prove to man!
