Introduction to the Science of Sociology Part 50

Here is one of the cases in which the temporal order of events presents a marked a.n.a.logy with the spatial order. Out of individuals existing side by side, that is, apart from each other, a social unity is formed.

The inevitable separation which s.p.a.ce places between men is nevertheless overcome by the spiritual bond between them, so that there arises an appearance of unified interexistence. In like manner the temporal separation of individuals and of generations presents their union in our conceptions as a coherent, uninterrupted whole. In the case of persons spatially separated, this unity is effected by the reciprocity maintained between them across the dividing distance. The unity of complex being means nothing else than the cohesion of elements which is produced by the reciprocal exercise of forces. In the case of temporally separated persons, however, unity cannot be effected in this manner, because reciprocity is lacking. The earlier may influence the later, but the later cannot influence the earlier. Hence the persistence of the social unity in spite of shifting membership presents a peculiar problem which is not solved by explaining how the group came to exist at a given moment.

a) _Continuity by continuance of locality._--The first and most obvious element of the continuity of group unity is the continuance of the locality, of the place and soil on which the group lives. The state, still more the city, and also countless other a.s.sociations, owe their unity first of all to the territory which const.i.tutes the abiding substratum for all change of their contents. To be sure, the continuance of the locality does not of itself alone mean the continuance of the social unity, since, for instance, if the whole population of a state is driven out or enslaved by a conquering group, we speak of a changed civic group in spite of the continuance of the territory. Moreover, the unity of whose character we are speaking is psychical, and it is this psychical factor itself which makes the territorial substratum a unity.

After this has once taken place, however, the locality const.i.tutes an essential point of attachment for the further persistence of the group.

But it is only one such element, for there are groups that get along without a local substratum. On the one hand, there are the very small groups, like the family, which continue precisely the same after the residence is changed. On the other hand, there are the very large groups, like that ideal community of the "republic of letters," or the other international a.s.sociations in the interest of culture, or the groups conducting international commerce. Their peculiar character comes from entire independence of all attachment to a definite locality.

b) _Continuity through blood relationship._--In contrast with this more formal condition for the maintenance of the group is the physiological connection of the generations. Community of stock is not always enough to insure unity of coherence for a long time. In many cases the local unity must be added. The social unity of the Jews has been weakened to a marked degree since the dispersion, in spite of their physiological and confessional unity. It has become more compact in cases where a group of Jews have lived for a time in the same territory, and the efforts of the modern "Zionism" to restore Jewish unity on a larger scale calculate upon concentration in one locality. On the other hand, when other bonds of union fail, the physiological is the last recourse to which the self-maintenance of the group resorts. The more the German guilds declined, the weaker their inherent power of cohesion became, the more energetically did each guild attempt to make itself exclusive, that is, it insisted that no persons should be admitted as guildmasters except sons or sons-in-law of masters or the husbands of masters' widows.

The physiological coherence of successive generations is of incomparable significance for the maintenance of the unitary self of the group, for the special reason that the displacement of one generation by the following _does not take place all at once_. By virtue of this fact it comes about that a continuity is maintained which conducts the vast majority of the individuals who live in a given moment into the life of the next moment. The change, the disappearance and entrance of persons, affects in two contiguous moments a number relatively small compared with the number of those who remain constant. Another element of influence in this connection is the fact that human beings are not bound to a definite mating season, but that children are begotten at any time.

It can never properly be a.s.serted of a group, therefore, that at any given moment a new generation begins. The departure of the older and the entrance of the younger elements proceed so gradually and continuously that the group seems as much like a unified self as an organic body in spite of the change of its atoms.

If the change were instantaneous, it is doubtful if we should be justified in calling the group "the same" after the critical moment as before. The circ.u.mstance alone that the transition affected in a given moment only a minimum of the total life of the group makes it possible for the group to retain its selfhood through the change. We may express this schematically as follows: If the totality of individuals or other conditions of the life of the group be represented by a, b, c, d, e; in a later moment by m, n, o, p, q; we may nevertheless speak of the persistence of identical selfhood if the development takes the following course: a, b, c, d, e--m, b, c, d, e--m, n, c, d, e--m, n, o, d, e--m, n, o, p, e--m, n, o, p, q. In this case each stage is differentiated from the contiguous stage by only one member, and at each moment it shares the same chief elements with its neighboring moments.

c) _Continuity through membership in the group._--This continuity in change of the individuals who are the vehicles of the group unity is most immediately and thoroughly visible when it rests upon procreation.

The same form is found, however, in cases where this physical agency is excluded, as, for example, within the Catholic clerus. Here the continuity is secured by provision that enough persons always remain in office to initiate the neophytes. This is an extremely important sociological fact. It makes bureaucracies tenacious, and causes their character and spirit to endure in spite of all shifting of individuals.

The physiological basis of self-maintenance here gives place to a psychological one. To speak exactly, the preservation of group ident.i.ty in this case depends, of course, upon the amount of invariability in the vehicles of this unity, but, at all events, the whole body of members belonging in the group at any given moment only separate from the group after they have been a.s.sociated with their successors long enough to a.s.similate the latter fully to themselves, i.e., to the spirit, the form, the tendency of the group. The immortality of the group depends upon the fact that the change is sufficiently slow and gradual.

The fact referred to by the phrase "immortality of the group" is of the greatest importance. The preservation of the identical selfhood of the group through a practically unlimited period gives to the group a significance which, _ceteris paribus_, is far superior to that of the individual. The life of the individual, with its purposes, its valuations, its force, is destined to terminate within a limited time, and to a certain extent each individual must start at the beginning.

Since the life of the group has no such a priori fixed time limit, and its forms are really arranged as though they were to last forever, the group accomplishes a summation of the achievements, powers, experiences, through which it makes itself far superior to the fragmentary individual lives. Since the early Middle Ages this has been the source of the power of munic.i.p.al corporations in England. Each had from the beginning the right, as Stubbs expresses it, "of perpetuating its existence by filling up vacancies as they occur." The ancient privileges were given expressly only to the burghers and their heirs. As a matter of fact, they were exercised as a right to add new members so that, whatever fate befell the members and their physical descendants, the corporation, as such, was held intact. This had to be paid for, to be sure, by the disappearance of the individual importance of the units behind their role as vehicles of the maintenance of the group, for the group security must suffer, the closer it is bound up with the perishable individuality of the units. On the other hand, the more anonymous and unpersonal the unit is, the more fit is he to step into the place of another, and so to insure to the group uninterrupted self-maintenance. This was the enormous advantage through which during the Wars of the Roses the Commons repulsed the previously superior power of the upper house. A battle that destroyed half the n.o.bility of the country took also from the House of Lords one-half its force, because this is attached to the personalities. The House of Commons is in principle a.s.sured against such weakening. That estate at last got predominance which, through the equalizing of its members, demonstrated the most persistent power of group existence. This circ.u.mstance gives every group an advantage in compet.i.tion with an individual.

d) _Continuity through leadership._--On this account special arrangements are necessary so soon as the life of the group is intimately bound up with that of a leading, commanding individual. What dangers to the integrity of the group are concealed in this sociological form may be learned from the history of all interregnums--dangers which, of course, increase in the same ratio in which the ruler actually forms the central point of the functions through which the group preserves its unity, or, more correctly, at each moment creates its unity anew.

Consequently a break between rulers may be a matter of indifference where the prince only exercises a nominal sway--"reigns, but does not govern"--while, on the other hand, we observe even in the swarm of bees that anarchy results so soon as the queen is removed. Although it is entirely false to explain this latter phenomenon by a.n.a.logy of a human ruler, since the queen bee gives no orders, yet the queen occupies the middle point of the activity of the hive. By means of her antennae she is in constant communication with the workers, and so all the signals coursing through the hive pa.s.s through her. By virtue of this very fact the hive feels itself a unity, and this unity dissolves with the disappearance of the functional center.

e) _Continuity through the hereditary principle._--In political groups the attempt is made to guard against all the dangers of personality, particularly those of possible intervals between the important persons, by the principle: "The king never dies." While in the early Middle Ages the tradition prevailed that when the king dies his peace dies with him, this newer principle contains provision for the self-preservation of the group. It involves an extraordinarily significant sociological conception, viz., the king is no longer king as a person, but the reverse is the case, that is, his person is only the in itself irrelevant vehicle of the abstract kingship, which is as unalterable as the group itself, of which the kingship is the apex. The group reflects its immortality upon the kingship, and the sovereign in return brings that immortality to visible expression in his own person, and by so doing reciprocally strengthens the vitality of the group. That mighty factor of social coherence which consists of loyalty of sentiment toward the reigning power might appear in very small groups in the relation of fidelity toward the person of the ruler. For large groups the definition that Stubbs once gave must certainly apply, viz.: "Loyalty is a habit of strong and faithful attachment to a person, not so much by reason of his personal character as of his official position." By becoming objectified in the deathless office, the princely principle gains a new psychological power for concentration and cohesion within the group, while the old princely principle that rested on the mere personality of the prince necessarily lost power as the size of the group increased.

f) _Continuity through a material symbol._--The objectification of the coherence of the group may also do away with the personal form to such an extent that it attaches itself to a material symbol. Thus in the German lands in the Middle Ages the imperial jewels were looked upon as the visible realization of the idea of the realm and of its continuity, so that the possession of them gave to a pretender a decided advantage over all other aspirants, and this was one of the influences which evidently a.s.sisted the heir of the body of the deceased emperor in securing the succession.

In view of the destructibility of a material object, since too this disadvantage cannot be offset, as in the case of a person, by the continuity of heredity, it is very dangerous for the group to seek such a support for its self-preservation. Many a regiment has lost its coherence with the loss of its standard. Many kinds of a.s.sociations have dissolved after their palladium, their storehouse, their grail, was destroyed. When, however, the social coherence is lost in this way, it is safe to say that it must have suffered serious internal disorder before, and that in this case the loss of the external symbol representing the unity of the group is itself only the symbol that the social elements have lost their coherence. When this last is not the case, the loss of the group symbol not only has no disintegrating effect but it exerts a direct integrating influence. While the symbol loses its corporeal reality, it may, as mere thought, longing, ideal, work much more powerfully, profoundly, indestructibly. We may get a good view of these two opposite influences of the forms of destruction of the group symbol upon the solidity of the group by reference to the consequences of the destruction of the Jewish temple by t.i.tus. The hierarchal Jewish state was a thorn in the flesh of the Roman statecraft that aimed at the unity of the empire. The purpose of dissolving this state was accomplished, so far as a certain number of the Jews were concerned, by the destruction of the temple. Such was the effect with those who cared little, anyway, about this centralization. Thus the alienation of the Pauline Christians from Judaism was powerfully promoted by this event.

For the Palestinian Jews, on the other hand, the breach between Judaism and the rest of the world was deepened. By this destruction of its symbol their national religious exclusiveness was heightened to desperation.

g) _Continuity through group honor._--The sociological significance of honor as a form of cohesion is extraordinarily great. Through the appeal to honor, society secures from its members the kind of conduct conducive to its own preservation, particularly within the spheres of conduct intermediate between the purview of the criminal code, on the one hand, and the field of purely personal morality, on the other. By the demands upon its members contained in the group standard of honor the group preserves its unified character and its distinctness from the other groups within the same inclusive a.s.sociation. The essential thing is the specific idea of honor in narrow groups--family honor, officers' honor, mercantile honor, yes, even the "honor among thieves." Since the individual belongs to various groups, the individual may, at the same time, be under the demands of several sorts of honor which are independent of each other. One may preserve his mercantile honor, or his scientific honor as an investigator, who has forfeited his family honor, and vice versa; the robber may strictly observe the requirements of thieves' honor after he has violated every other; a woman may have lost her womanly honor and in every other respect be most honorable, etc.

Thus honor consists in the relation of the individual to a particular circle, which in this respect manifests its separateness, its sociological distinctness, from other groups.

h) _Continuity through specialized organs._--From such recourse of social self-preservation to individual persons, to a material substance, to an ideal conception, we pa.s.s now to the cases in which social persistence takes advantage of an organ composed of a number of persons.

Thus a religious community embodies its coherence and its life principle in its priesthood; a political community its inner principle of union in its administrative organization, its union against foreign power in its military system; this latter in its corps of officers; every permanent union in its official head; transitory a.s.sociations in their committees; political parties in their parliamentary representatives.

B. THE NATURAL FORMS OF COMMUNICATION

1. Sociology of the Senses: Visual Interaction[138]

It is through the medium of the senses that we perceive our fellow-men.

This fact has two aspects of fundamental sociological significance: (a) that of appreciation, and (b) that of comprehension.

a) _Appreciation._--Sense-impressions may induce in us affective responses of pleasure or pain, of excitement or calm, of tension or relaxation, produced by the features of a person, or by the tone of his voice, or by his mere physical presence in the same room. These affective responses, however, do not enable us to understand or to define the other person. Our emotional response to the sense-image of the other leaves his real self outside.

b) _Comprehension._--The sense-impression of the other person may develop in the opposite direction when it becomes the medium for understanding the other. What I see, hear, feel of him is only the bridge over which I reach his real self. The sound of the voice and its meaning, perhaps, present the clearest ill.u.s.tration. The speech, quite as much as the appearance, of a person, may be immediately either attractive or repulsive. On the other hand, what he says enables us to understand not only his momentary thoughts but also his inner self. The same principle applies to all sense-impressions.

The sense-impressions of any object produce in us not only emotional and aesthetic att.i.tudes toward it but also an understanding of it. In the case of reaction to non-human objects, these two responses are, in general, widely separated. We may appreciate the emotional value of any sense-impression of an object. The fragrance of a rose, the charm of a tone, the grace of a bough swaying in the wind, is experienced as a joy engendered within the soul. On the other hand, we may desire to understand and to comprehend the rose, or the tone, or the bough. In the latter case we respond in an entirely different way, often with conscious endeavor. These two diverse reactions which are independent of each other are with human beings generally integrated into a unified response. Theoretically, our sense-impressions of a person may be directed on the one hand to an appreciation of his emotional value, or on the other to an impulsive or deliberate understanding of him.

Actually, these two reactions are coexistent and inextricably interwoven as the basis of our relation to him. Of course, appreciation and comprehension develop in quite different degrees. These two diverse responses--to the tone of voice and to the meaning of the utterance; to the appearance of a person and to his individuality; to the attraction or repulsion of his personality and to the impulsive judgment upon his character as well as many times upon his grade of culture--are present in any perception in very different degrees and combinations.

Of the special sense-organs, the eye has a uniquely sociological function. The union and interaction of individuals is based upon mutual glances. This is perhaps the most direct and purest reciprocity which exists anywhere. This highest psychic reaction, however, in which the glances of eye to eye unite men, crystallizes into no objective structure; the unity which momentarily arises between two persons is present in the occasion and is dissolved in the function. So tenacious and subtle is this union that it can only be maintained by the shortest and straightest line between the eyes, and the smallest deviation from it, the slightest glance aside, completely destroys the unique character of this union. No objective trace of this relationship is left behind, as is universally found, directly or indirectly, in all other types of a.s.sociations between men, as, for example, in interchange of words. The interaction of eye and eye dies in the moment in which the directness of the function is lost. But the totality of social relations of human beings, their self-a.s.sertion and self-abnegation, their intimacies and estrangements, would be changed in unpredictable ways if there occurred no glance of eye to eye. This mutual glance between persons, in distinction from the simple sight or observation of the other, signifies a wholly new and unique union between them.

The limits of this relation are to be determined by the significant fact that the glance by which the one seeks to perceive the other is itself expressive. By the glance which reveals the other, one discloses himself. By the same act in which the observer seeks to know the observed, he surrenders himself to be understood by the observer. The eye cannot take unless at the same time it gives. The eye of a person discloses his own soul when he seeks to uncover that of another. What occurs in this direct mutual glance represents the most perfect reciprocity in the entire field of human relationships.

Shame causes a person to look at the ground to avoid the glance of the other. The reason for this is certainly not only because he is thus spared the visible evidence of the way in which the other regards his painful situation, but the deeper reason is that the lowering of his glance to a certain degree prevents the other from comprehending the extent of his confusion. The glance in the eye of the other serves not only for me to know the other but also enables him to know me. Upon the line which unites the two eyes, it conveys to the other the real personality, the real att.i.tude, and the real impulse. The "ostrich policy" has in this explanation a real justification: who does not see the other actually conceals himself in part from the observer. A person is not at all completely present to another, when the latter sees him, but only when he also sees the other.

The sociological significance of the eye has special reference to the expression of the face as the first object of vision between man and man. It is seldom clearly understood to what an extent even our practical relations depend upon mutual recognition, not only in the sense of all external characteristics, as the momentary appearance and att.i.tude of the other, but what we know or intuitively perceive of his life, of his inner nature, of the immutability of his being, all of which colors unavoidably both our transient and our permanent relations with him. The face is the geometric chart of all these experiences. It is the symbol of all that which the individual has brought with him as the pre-condition of his life. In the face is deposited what has been precipitated from past experience as the substratum of his life, which has become crystallized into the permanent features of his face. To the extent to which we thus perceive the face of a person, there enters into social relations, in so far as it serves practical purposes, a super-practical element. It follows that a man is first known by his countenance, not by his acts. The face as a medium of expression is entirely a theoretical organ; it does not act, as the hand, the foot, the whole body; it transacts none of the internal or practical relations of the man, it only tells about him. The peculiar and important sociological art of "knowing" transmitted by the eye is determined by the fact that the countenance is the essential object of the interindividual sight. This knowing is still somewhat different from understanding. To a certain extent, and in a highly variable degree, we know at first glance with whom we have to do. Our unconsciousness of this knowledge and its fundamental significance lies in the fact that we direct our attention from this self-evident intuition to an understanding of special features which determine our practical relations to a particular individual. But if we become conscious of this self-evident fact, then we are amazed how much we know about a person in the first glance at him. We do not obtain meaning from his expression, susceptible to a.n.a.lysis into individual traits. We cannot unqualifiedly say whether he is clever or stupid, good- or ill-natured, temperamental or phlegmatic. All these traits are general characteristics which he shares with unnumbered others. But what this first glance at him transmits to us cannot be a.n.a.lyzed or appraised into any such conceptual and expressive elements. Yet our initial impression remains ever the keynote of all later knowledge of him; it is the direct perception of his individuality which his appearance, and especially his face, discloses to our glance.

The sociological att.i.tude of the blind is entirely different from that of the deaf-mute. For the blind, the other person is actually present only in the alternating periods of his utterance. The expression of the anxiety and unrest, the traces of all past events, exposed to view in the faces of men, escape the blind, and that may be the reason for the peaceful and calm disposition, and the unconcern toward their surroundings, which is so often observed in the blind. Indeed, the majority of the stimuli which the face presents are often puzzling; in general, what we see of a man will be interpreted by what we hear from him, while the opposite is more unusual. Therefore the one who sees, without hearing, is much more perplexed, puzzled, and worried, than the one who hears without seeing. This principle is of great importance in understanding the sociology of the modern city.

Social life in the large city as compared with the towns shows a great preponderance of occasions to _see_ rather than to _hear_ people. One explanation lies in the fact that the person in the town is acquainted with nearly all the people he meets. With these he exchanges a word or a glance, and their countenance represents to him not merely the visible but indeed the entire personality. Another reason of especial significance is the development of public means of transportation.

Before the appearance of omnibuses, railroads, and street cars in the nineteenth century, men were not in a situation where for periods of minutes or hours they could or must look at each other without talking to one another. Modern social life increases in ever growing degree the role of mere visual impression which always characterizes the preponderant part of all sense relationship between man and man, and must place social att.i.tudes and feelings upon an entirely changed basis.

The greater perplexity which characterizes the person who only sees, as contrasted with the one who only hears, brings us to the problems of the emotions of modern life: the lack of orientation in the collective life, the sense of utter lonesomeness, and the feeling that the individual is surrounded on all sides by closed doors.

2. The Expression of the Emotions[139]

Actions of all kinds, if regularly accompanying any state of the mind, are at once recognized as expressive. These may consist of movements of any part of the body, as the wagging of a dog's tail, the shrugging of a man's shoulders, the erection of the hair, the exudation of perspiration, the state of the capillary circulation, labored breathing, and the use of the vocal or other sound-producing instruments. Even insects express anger, terror, jealousy, and love by their stridulation.

With man the respiratory organs are of especial importance in expression, not only in a direct, but to a still higher degree in an indirect, manner.

Few points are more interesting in our present subject than the extraordinarily complex chain of events which lead to certain expressive movements. Take, for instance, the oblique eyebrows of a man suffering from grief or anxiety. When infants scream loudly from hunger or pain, the circulation is affected, and the eyes tend to become gorged with blood; consequently the muscles surrounding the eyes are strongly contracted as a protection. This action, in the course of many generations, has become firmly fixed and inherited; but when, with advancing years and culture, the habit of screaming is partially repressed, the muscles round the eyes still tend to contract, whenever even slight distress is felt. Of these muscles, the pyramidals of the nose are less under the control of the will than are the others, and their contraction can be checked only by that of the central fasciae of the frontal muscle; these latter fasciae draw up the inner ends of the eyebrows and wrinkle the forehead in a peculiar manner, which we instantly recognize as the expression of grief or anxiety. Slight movements, such as these just described, or the scarcely perceptible drawing down of the corners of the mouth, are the last remnants or rudiments of strongly marked and intelligible movements. They are as full of significance to us in regard to expression as are ordinary rudiments to the naturalist in the cla.s.sification and genealogy of organic beings.

That the chief expressive actions exhibited by man and by the lower animals are now innate or inherited--that is, have not been learned by the individual--is admitted by everyone. So little has learning or imitation to do with several of them that they are from the earliest days and throughout life quite beyond our control; for instance, the relaxation of the arteries of the skin in blushing, and the increased action of the heart in anger. We may see children only two or three years old, and even those born blind, blushing from shame; and the naked scalp of a very young infant reddens from pa.s.sion. Infants scream from pain directly after birth, and all their features then a.s.sume the same form as during subsequent years. These facts alone suffice to show that many of our most important expressions have not been learned; but it is remarkable that some, which are certainly innate, require practice in the individual before they are performed in a full and perfect manner; for instance, weeping and laughing. The inheritance of most of our expressive actions explains the fact that those born blind display them, as I hear from the Rev. R. H. Blair, equally well with those gifted with eyesight. We can thus also understand the fact that the young and the old of widely different races, both with man and animals, express the same state of mind by the same movement.

We are so familiar with the fact of young and old animals displaying their feelings in the same manner that we hardly perceive how remarkable it is that a young puppy should wag its tail when pleased, depress its ears and uncover its canine teeth when pretending to be savage, just like an old dog; or that a kitten should arch its little back and erect its hair when frightened and angry, like an old cat. When, however, we turn to less common gestures in ourselves, which we are accustomed to look at as artificial or conventional--such as shrugging the shoulders as a sign of impotence, or the raising the arms with open hands and extended fingers as a sign of wonder--we feel perhaps too much surprise at finding that they are innate. That these and some other gestures are inherited we may infer from their being performed by very young children, by those born blind, and by the most widely distinct races of man. We should also bear in mind that new and highly peculiar tricks, in a.s.sociation with certain states of the mind, are known to have arisen in certain individuals and to have been afterward transmitted to their offspring, in some cases for more than one generation.

Certain other gestures, which seem to us so natural that we might easily imagine that they were innate, apparently have been learned like the words of a language. This seems to be the case with the joining of the uplifted hands and the turning up of the eyes in prayer. So it is with kissing as a mark of affection; but this is innate, in so far as it depends on the pleasure derived from contact with a beloved person. The evidence with respect to the inheritance of nodding and shaking the head as signs of affirmation and negation is doubtful, for they are not universal, yet seem too general to have been independently acquired by all the individuals of so many races.

We will now consider how far the will and consciousness have come into play in the development of the various movements of expression. As far as we can judge, only a few expressive movements, such as those just referred to, are learned by each individual; that is, were consciously and voluntarily performed during the early years of life for some definite object, or in imitation of others, and then became habitual.

The far greater number of the movements of expression, and all the more important ones, are, as we have seen, innate or inherited; and such cannot be said to depend on the will of the individual. Nevertheless, all those included under our first principle were at first voluntarily performed for a definite object, namely, to escape some danger, to relieve some distress, or to gratify some desire. For instance, there can hardly be a doubt that the animals which fight with their teeth have acquired the habit of drawing back their ears closely to their heads when feeling savage from their progenitors having voluntarily acted in this manner in order to protect their ears from being torn by their antagonists; for those animals which do not fight with their teeth do not thus express a savage state of mind. We may infer as highly probable that we ourselves have acquired the habit of contracting the muscles round the eyes whilst crying gently, that is, without the utterance of any loud sound, from our progenitors, especially during infancy, having experienced during the act of screaming an uncomfortable sensation in their eyeb.a.l.l.s. Again, some highly expressive movements result from the endeavor to check or prevent other expressive movements; thus the obliquity of the eyebrows and the drawing down of the corners of the mouth follow from the endeavor to prevent a screaming-fit from coming on or to check it after it has come on. Here it is obvious that the consciousness and will must at first have come into play; not that we are conscious in these or in other such cases what muscles are brought into action, any more than when we perform the most ordinary voluntary movements.

The power of communication between the members of the same tribe by means of language has been of paramount importance in the development of man; and the force of language is much aided by the expressive movements of the face and body. We perceive this at once when we converse on an important subject with any person whose face is concealed. Nevertheless there are no grounds, as far as I can discover, for believing that any muscle has been developed or even modified exclusively for the sake of expression. The vocal and other sound-producing organs by which various expressive noises are produced seem to form a partial exception; but I have elsewhere attempted to show that these organs were first developed for s.e.xual purposes, in order that one s.e.x might call or charm the other. Nor can I discover grounds for believing that any inherited movement which now serves as a means of expression was at first voluntarily and consciously performed for this special purpose--like some of the gestures and the finger-language used by the deaf and dumb.

On the contrary, every true or inherited movement of expression seems to have had some natural and independent origin. But when once acquired, such movements may be voluntarily and consciously employed as a means of communication. Even infants, if carefully attended to, find out at a very early age that their screaming brings relief, and they soon voluntarily practice it. We may frequently see a person voluntarily raising his eyebrows to express surprise, or smiling to express pretended satisfaction and acquiescence. A man often wishes to make certain gestures conspicuous or demonstrative, and will raise his extended arms with widely opened fingers above his head to show astonishment or lift his shoulders to his ears to show that he cannot or will not do something.

We have seen that the study of the theory of expression confirms to a certain limited extent the conclusion that man is derived from some lower animal form, and supports the belief of the specific or subspecific unity of the several races; but as far as my judgment serves, such confirmation was hardly needed. We have also seen that expression in itself, or the language of the emotions, as it has sometimes been called, is certainly of importance for the welfare of mankind. To understand, as far as is possible, the source or origin of the various expressions which may be hourly seen on the faces of the men around us, not to mention our domesticated animals, ought to possess much interest for us. From these several causes we may conclude that the philosophy of our subject has well deserved that attention which it has already received from several excellent observers, and that it deserves still further attention, especially from any able physiologist.

3. Blushing[140]

Blushing is the most peculiar and the most human of all expressions.

Monkeys redden from pa.s.sion, but it would require an overwhelming amount of evidence to make us believe that any animal could blush. The reddening of the face from a blush is due to the relaxation of the muscular coats of the small arteries, by which the capillaries become filled with blood; and this depends on the proper vasomotor center being affected. No doubt if there be at the same time much mental agitation, the general circulation will be affected; but it is not due to the action of the heart that the network of minute vessels covering the face becomes under a sense of shame gorged with blood. We can cause laughing by tickling the skin, weeping or frowning by a blow, trembling from the fear of pain, and so forth; but we cannot cause a blush by any physical means--that is, by any action on the body. It is the mind which must be affected. Blushing is not only involuntary, but the wish to restrain it, by leading to self-attention, actually increases the tendency.

The young blush much more freely than the old, but not during infancy, which is remarkable, as we know that infants at a very early age redden from pa.s.sion. I have received authentic accounts of two little girls blushing at the ages of between two and three years; and of another sensitive child, a year older, blushing when reproved for a fault. Many children at a somewhat more advanced age blush in a strongly marked manner. It appears that the mental powers of infants are not as yet sufficiently developed to allow of their blushing. Hence, also, it is that idiots rarely blush. Dr. Crichton Browne observed for me those under his care, but never saw a genuine blush, though he has seen their faces flush, apparently from joy, when food was placed before them, and from anger. Nevertheless some, if not utterly degraded, are capable of blushing. A microcephalous idiot, for instance, thirteen years old, whose eyes brightened a little when he was pleased or amused, has been described by Dr. Behn as blushing and turning to one side when undressed for medical examination.

Women blush much more than men. It is rare to see an old man, but not nearly so rare to see an old woman, blushing. The blind do not escape.

Laura Bridgman, born in this condition, as well as completely deaf, blushes. The Rev. R. H. Blair, princ.i.p.al of the Worcester College, informs me that three children born blind, out of seven or eight then in the asylum, are great blushers. The blind are not at first conscious that they are observed, and it is a most important part of their education, as Mr. Blair informs me, to impress this knowledge on their minds; and the impression thus gained would greatly strengthen the tendency to blush, by increasing the habit of self-attention.
