The reality and subtlety of the influence of odors is further shown, by the cases in which very intense effects are produced even by the temporary inhalation of flowers or perfumes or other odors. Such cases of idiosyncrasy in which a person-frequently of somewhat neurotic temperament-becomes acutely sensitive to some odor or odors have been recorded in medical literature for many centuries. In these cases the obnoxious odor produces congestion of the respiratory pa.s.sages, sneezing, headache, fainting, etc., but occasionally, it has been recorded, even death. (Dr. J. N. Mackenzie, in his interesting and learned paper on "The Production of the so-called "Rose Cold," etc.," American Journal of Medical Sciences, January, 1886, quotes many cases, and gives a number of references to ancient medical authors; see also Layet, art. "Odeur," Dictionnaire Encyclopedique des Sciences Medicales.)
An interesting phenomenon of the group-though it is almost too common to be described as an idiosyncrasy-is the tendency of the odor of certain flowers to affect the voice and sometimes even to produce complete loss of voice. The mechanism of the process is not fully understood, but it would appear that congestion and paresis of the larynx is produced and spasm of the bronchial tube. Botallus in 1565 recorded cases in which the scent of flowers brought on difficulty of breathing, and the danger of flowers from this point of view is well recognized by professional singers. Joal has studied this question in an elaborate paper (summarized in the British Medical Journal, March 3, 1895), and Dr. Cabanes has brought together (Figaro, January 20, 1894) the experiences of a number of well-known singers, teachers of singing, and laryngologists. Thus, Madame Renee Richard, of the Paris Opera, has frequently found that when her pupils have arrived with a bunch of violets fastened to the bodice or even with a violet and iris sachet beneath the corset, the voice has been marked by weakness and, on using the laryngoscope, she has found the vocal cords congested. Madame Calve confirmed this opinion, and stated that she was specially sensitive to tuberose and mimosa, and that on one occasion a bouquet of white lilac has caused her, for a time, complete loss of voice. The flowers mentioned are equally dangerous to a number of other singers; the most injurious flower of all is found to be the violet. The rose is seldom mentioned, and artificial perfumes are comparatively harmless, though some singers consider it desirable to be cautious in using them.

Fere records the case of a neurasthenic lady whose s.e.xual coldness toward her husband only disappeared after the abandonment of a perfume (in which heliotrope was apparently the chief const.i.tuent) she had been accustomed to use in excessive amounts.

It is perhaps significant that many colors are especially liable to produce skin disorders, especially urticaria; a number of cases have been recorded by Joal, Journal de Medecine, July 10, 1899.

The Place of Smell in Human s.e.xual Selections-It has given Place to the Predominance of Vision largely because in Civilized Man it Fails to Act at a Distance-It still Plays a Part by Contributing to the Sympathies or the Antipathies of Intimate Contact.
When we survey comprehensively the extensive field we have here rapidly traversed, it seems not impossible to gain a fairly accurate view of the special place which olfactory sensations play in human s.e.xual selection. The special peculiarity of this group of sensations in man, and that which gives them an importance they would not otherwise possess, is due to the fact that we here witness the decadence of a sense which in man"s remote ancestors was the very chiefest avenue of s.e.xual allurement. In man, even the most primitive man,-to some degree even in the apes,-it has declined in importance to give place to the predominance of vision.[85] Yet, at that lower threshold of acuity at which it persists in man it still bathes us in a more or less constant atmosphere of odors, which perpetually move us to sympathy or to antipathy, and which in their finer manifestations we do not neglect, but even cultivate with the increase of our civilization.
It thus comes about that the grosser manifestations of s.e.xual allurement by smell belong, so far as man is concerned, to a remote animal past which we have outgrown and which, on account of the diminished acuity of our olfactory organs, we could not completely recall even if we desired to; the sense of sight inevitably comes into play long before it is possible for close contact to bring into action the sense of smell. But the latent possibilities of s.e.xual allurement by olfaction, which are inevitably embodied in the nervous structure we have inherited from our animal ancestors, still remain ready to be called into play. They emerge prominently from time to time in exceptional and abnormal persons. They tend to play an unusually larger part in the psychic lives of neurasthenic persons, with their sensitive and comparatively unbalanced nervous systems, and this is doubtless the reason why poets and men of letters have insisted on olfactory impressions so frequently and to so notable a degree; for the same reason s.e.xual inverts are peculiarly susceptible to odors. For a different reason, warmer climates, which heighten all odors and also favor the growth of powerfully odorous plants, lead to a heightened susceptibility to the s.e.xual and other attractions of smell even among normal persons; thus we find a general tendency to delight in odors throughout the East, notably in India, among the ancient Hebrews, and in Mohammedan lands.
Among the ordinary civilized population in Europe the s.e.xual influences of smell play a smaller and yet not altogether negligible part. The diminished prominence of odors only enables them to come into action, as s.e.xual influences, on close contact, when, in some persons at all events, personal odors may have a distinct influence in heightening sympathy or arousing antipathy. The range of variation among individuals is in this matter considerable. In a few persons olfactory sympathy or antipathy is so p.r.o.nounced that it exerts a decisive influence in their s.e.xual relationships; such persons are of olfactory type. In other persons smell has no part in const.i.tuting s.e.xual relationships, but it comes into play in the intimate a.s.sociation of love, and acts as an additional excitant; when reinforced by a.s.sociation such olfactory impressions may at times prove irresistible. Other persons, again, are neutral in this respect, and remain indifferent either to the sympathetic or antipathetic working of personal odors, unless they happen to be extremely marked. It is probable that the majority of refined and educated people belong to the middle group of those persons who are not of predominantly olfactory type, but are liable from time to time to be influenced in this manner. Women are probably at least as often affected in this manner as men, probably more often.
On the whole, it may be said that in the usual life of man odors play a not inconsiderable part and raise problems which are not without interest, but that their demonstrable part in actual s.e.xual selection-whether in preferential mating or in a.s.sortative mating-is comparatively small.

The sense of rhythm-on which it may be said that the sensory exciting effects of hearing, including music, finally rest-may probably be regarded as a fundamental quality of neuro-muscular tissue. Not only are the chief physiological functions of the body, like the circulation and the respiration, definitely rhythmical, but our senses insist on imparting a rhythmic grouping even to an absolutely uniform succession of sensations. It seems probable, although this view is still liable to be disputed, that this rhythm is the result of kinaesthetic sensations,-sensations arising from movement or tension started reflexly in the muscles by the external stimuli,-impressing themselves on the sensations that are thus grouped.[86] We may thus say, with Wilks, that music appears to have had its origin in muscular action.[87]
Whatever its exact origin may be, rhythm is certainly very deeply impressed on our organisms. The result is that, whatever lends itself to the neuro-muscular rhythmical tendency of our organisms, whatever tends still further to heighten and develop that rhythmical tendency, exerts upon us a very decidedly stimulating and exciting influence.
All muscular action being stimulated by rhythm, in its simple form or in its more developed form as music, rhythm is a stimulant to work. It has even been argued by Bucher and by Wundt[88] that human song had its chief or exclusive origin in rhythmical vocal accompaniments to systematized work. This view cannot, however, be maintained; systematized work can scarcely be said to exist, even to-day, among most very primitive races; it is much more probable that rhythmical song arose at a period antecedent to the origin of systematized work, in the primitive military, religious, and erotic dances, such as exist in a highly developed degree among the Australians and other savage races who have not evolved co-ordinated systematic labor. There can, however, be no doubt that as soon as systematic work appears the importance of vocal rhythm in stimulating its energy is at once everywhere recognized. Bucher has brought together innumerable examples of this a.s.sociation, and in the march music of soldiers and the heaving and hoisting songs of sailors we have instances that have universally persisted into civilization, although in civilization the rhythmical stimulation of work, physiologically sound as is its basis, tends to die out. Even in the laboratory the influence of simple rhythm in increasing the output of work may be demonstrated; and Fere found with the ergograph that a rhythmical grouping of the movements caused an increase of energy which often more than compensated the loss of time caused by the rhythm.[89]
Rhythm is the most primitive element of music, and the most fundamental. Wallaschek, in his book on Primitive Music, and most other writers on the subject are agreed on this point. "Rhythm," remarks an American anthropologist,[90] "naturally precedes the development of any fine perception of differences in pitch, of time-quality, or of tonality. Almost, if not all, Indian songs," he adds, "are as strictly developed out of modified repet.i.tions of a motive as are the movements of a Mozart or a Beethoven symphony." "In all primitive music," a.s.serts Alice C. Fletcher,[91] "rhythm is strongly developed. The pulsations of the drum and the sharp crash of the rattles are thrown against each other and against the voice, so that it would seem that the pleasure derived by the performers lay not so much in the tonality of the song as in the measured sounds arrayed in contesting rhythm, and which by their clash start the nerves and spur the body to action, for the voice which alone carries the tone is often subordinated and treated as an additional instrument." Groos points out that a melody gives us the essential impression of a voice that dances;[92] it is a translation of spatial movement into sound, and, as we shall see, its physiological action on the organism is a reflection of that which, as we have elsewhere found,[93] dancing itself produces, and thus resembles that produced by the sight of movement. Dancing, music, and poetry were primitively so closely allied as to be almost identical; they were still inseparable among the early Greeks. The refrains in our English ballads indicate the dancer"s part in them. The technical use of the word "foot" in metrical matters still persists to show that a poem is fundamentally a dance.
Aristotle seems to have first suggested that rhythm and melodies are motions, as actions are motions, and therefore signs of feeling. "All melodies are motions," says Helmholtz. "Graceful rapidity, gravel procession, quiet advance, wild leaping, all these different characters of motion and a thousand others can be represented by successions of tones. And as music expresses these motions it gives an expression also to those mental conditions which naturally evoke similar motions, whether of the body and the voice, or of the thinking and feeling principle itself." (Helmholtz, On the Sensations of Tone, translated by A. J. Ellis, 1885, p. 250.)
From another point of view the motor stimulus of music has been emphasized by Cyples: "Music connects with the only sense that can be perfectly manipulated. Its emotional charm has struck men as a great mystery. There appears to be no doubt whatever that it gets all the marvelous effects it has beyond the mere pleasing of the ear, from its random, but mult.i.tudinous summonses of the efferent activity, which at its vague challenges stirs unceasingly in faintly tumultuous irrelevancy. In this way, music arouses aimlessly, but splendidly, the sheer, as yet unfulfilled, potentiality within us." (W. Copies, The Process of Human Experience, p. 743.)
The fundamental element of transformed motion in music has been well brought out in a suggestive essay by Goblot ("La Musique Descriptive," Revue Philosophique, July, 1901): "Sung or played, melody figures to the ear a successive design, a moving arabesque. We talk of ascending and descending the gamut, of high notes or low notes; the; higher voice of woman is called soprano, or above, the deeper voice of man is called ba.s.s. Grave tones were so called by the Greeks because they seemed heavy and to incline downward. Sounds seem to be subject to the action of gravity; so that some rise and others fall. Baudelaire, speaking of the prelude to Lohengrin, remarks: "I felt myself delivered from the bonds of weight." And when Wagner sought to represent, in the highest regions of celestial s.p.a.ce, the apparition of the angels bearing the Holy Grail to earth, he uses very high notes, and a kind of chorus played exclusively by the violins, divided into eight parts, in the highest notes of their register. The descent to earth of the celestial choir is rendered by lower and lower notes, the progressive disappearance of which represents the reascension to the ethereal regions.
"Sounds seem to rise and fall; that is a fact. It is difficult to explain it. Some have seen in it a habit derived from the usual notation by which the height of the note corresponds to its height in the score. But the impression is too deep and general to be explained by so superficial and recent a cause. It has been suggested also that high notes are generally produced by small and light bodies, low notes by heavy bodies. But that is not always true. It has been said, again, that high notes in nature are usually produced by highly placed objects, while low notes arise from caves and low placed regions. But the thunder is heard in the sky, and the murmur of a spring or the song of a cricket arise from the earth. In the human voice, again, it is said, the low notes seem to resound in the chest, high notes in the head. All this is unsatisfactory. We cannot explain by such coa.r.s.e a.n.a.logies an impression which is very precise, and more sensible (this fact has its importance) for an interval of half a tone than for an interval of an octave. It is probable that the true explanation is to be found in the still little understood connection between the elements of our nervous apparatus.
"Nearly all our emotions tend to produce movement. But education renders us economical of our acts. Most of these movements are repressed, especially in the adult and civilized man, as harmful, dangerous, or merely useless. Some are not completed, others are reduced to a faint incitation which externally is scarcely perceptible. Enough remain to const.i.tute all that is expressive in our gestures, physiognomy, and att.i.tudes. Melodic intervals possess in a high degree this property of provoking impulses of movement, which, even when repressed, leave behind internal sensations and motor images. It would be possible to study these facts experimentally if we had at our disposition a human being who, while retaining his sensations and their motor reactions, was by special circ.u.mstances rendered entirely spontaneous like a sensitive automaton, whose movements were neither intentionally produced nor intentionally repressed. In this way, melodic intervals in a hypnotized subject might be very instructive."
A number of experiments of the kind desired by Goblot had already been made by A. de Rochas in a book, copiously ill.u.s.trated by very numerous instantaneous photographs, ent.i.tled Les Sentiments, la Musique et la Geste, 1900. Chapter III. De Rochas experimented on a single subject, Lina, formerly a model, who was placed in a condition of slight hypnosis, when various simple fragments of music were performed: recitatives, popular airs, and more especially national dances, often from remote parts of the world. The subject"s gestures were exceedingly marked and varied in accordance with the character of the music. It was found that she often imitated with considerable precision the actual gestures of dances she could never have seen. The same music always evoked the same gestures, as was shown by instantaneous photographs. This subject, stated to be a chaste and well-behaved girl, exhibited no indications of definite s.e.xual emotion under the influence of any kind of music. Some account is given in the same volume of other hypnotic experiments with music which were also negative as regards specific s.e.xual phenomena.
It must be noted that, as a physiological stimulus, a single musical note is effective, even apart from rhythm, as is well shown by Fere"s experiments with the dynamometer and the ergograph.[94] It is, however, the influence of music on muscular work which has been most frequently investigated, and both on brief efforts with the dynamometer and prolonged work with the ergograph it has been found to exert a stimulating influence. Thus, Scripture found that, while his own maximum thumb and finger grip with the dynamometer is 8 pounds, when the giant"s motive from Wagner"s Rheingold is played it rises to 8 pounds.[95] With the ergograph Tarchanoff found that lively music, in nervously sensitive persons, will temporarily cause the disappearance of fatigue, though slow music in a minor key had an opposite effect.[96] The varying influence on work with the ergograph of different musical intervals and different keys has been carefully studied by Fere with many interesting results. There was a very considerable degree of constancy in the results. Discords were depressing; most, but not all, major keys were stimulating; and most, but not all, minor keys depressing. In states of fatigue, however, the minor keys were more stimulating than the major, an interesting result in harmony with that stimulating influence of various painful emotions in states of organic fatigue which we have elsewhere encountered when investigating sadism.[97] "Our musical culture," Fere remarks, "only renders more perceptible to us the unconscious relationships which exist between musical art and our organisms. Those whom we consider more endowed in this respect have a deeper penetration of the phenomena accomplished within them; they feel more profoundly the marvelous reactions between the organism and the principles of musical art, they experience more strongly that art is within them."[98] Both the higher and the lower muscular processes, the voluntary and the involuntary, are stimulated by music. Darlington and Talbot, in t.i.tchener"s laboratory at Cornell University, found that the estimation of relative weights was aided by music.[99] Lombard found, when investigating the normal variations in the knee-jerk, that involuntary reflex processes are always reinforced by music; a military band playing a lively march caused the knee-jerk to increase at the loud pa.s.sages and to diminish at the soft pa.s.sages, while remaining always above the normal level.[100]
With this stimulating influence of rhythm and music on the neuro-muscular system-which may or may not be direct-there is a concomitant influence on the circulatory and breathing apparatus. During recent years a great many experiments have been made on man and animals bearing on the effects of music on the heart and respiration. Perhaps the earliest of these were carried out by the Russian physiologist Dogiel in 1880.[101] His methods were perhaps defective and his results, at all events as regards man, uncertain, but in animals the force and rapidity of the heart were markedly increased. Subsequent investigations have shown very clearly the influence of music on the circulatory and respiratory systems in man as well as in animals. That music has an apparently direct influence on the circulation of the brain is shown by the observations of Patrizi on a youth who had received a severe wound of the head which had removed a large portion of the skull wall. The stimulus of melody produced an immediate increase in the afflux of blood to the brain.[102]
In Germany the question was investigated at about the same time by Mentz.[103] Observing the pulse with a sphygmograph and Marey tambour he found distinct evidence of an effect on the heart; when attention was given to the music the pulse was quickened, in the absence of attention it was slowed; Mentz also found that pleasurable sensations tended to slow the pulse and disagreeable ones to quicken it.
Binet and Courtier made an elaborate series of experiments on the action of music on the respiration (with the double pneumograph), the heart, and the capillary circulation (with the plethysmograph of Hallion and Comte) on a single subject, a man very sensitive to music and himself a cultured musician. Simple musical sounds with no emotional content accelerated the respiration without changing its regularity or amplitude. Musical fragments, mostly sung, usually well known to the subject, and having an emotional effect on him, produced respiratory irregularity either in amplitude or rapidity of breathing, in two-thirds of the trials. Exciting music, such as military marches, accelerated the breathing more than sad melodies, but the intensity of the excitation had an effect at least as great as its quality, for intense excitations always produced both quickened and deeper breathing. The heart was quickened in harmony with the quickened breathing. Neither breathing nor heart was ever slowed. As regards the capillary pulsation, an influence was exerted chiefly, if not exclusively, by gay and exciting melodies, which produced a shrinking. Throughout the experiments it was found that the most profound physiological effects were exerted by those pieces which the subject found to be most emotional in their influence on him.[104]
Guibaud studied the question on a number of subjects, confirming and extending the conclusions of Binet and Courtier. He found that the reactions of different individuals varied, but that for the same individual reactions were constant. Circulatory reaction was more often manifest than respiratory reaction. The latter might be either a simultaneous modification of depth and of rapidity or of either of these. The circulatory reaction was a peripheral vasoconstriction with diminished fullness of pulse and slight acceleration of cardiac rhythm; there was never any distinct slowing of heart under the influence of music. Guibaud remarks that when people say they feel a shudder at some pa.s.sage of music, this sensation of cold finds its explanation in the production of a peripheral vasoconstriction which may be registered by the plethysmograph.[105]
Since music thus directly and powerfully affects the chief vital processes, it is not surprising that it should indirectly influence various viscera and functions. As Tarchanoff and others have demonstrated, it affects the skin, increasing the perspiration; it may produce a tendency to tears; it sometimes produces desire to urinate, or even actual urination, as in Scaliger"s case of the Gascon gentleman who was always thus affected on hearing the bagpipes. In dogs it has been shown by Tarchanoff and Wartanoff that auditory stimulation increases the consumption of oxygen 20 per cent., and the elimination of carbonic acid 17 per cent.
In addition to the effects of musical sound already mentioned, it may be added that, as Epstein, of Berne, has shown,[106] the other senses are stimulated under the influence of sound, and notably there is an increase in acuteness of vision which may be experimentally demonstrated. It is probable that this effect of music in heightening the impressions received by the other senses is of considerable significance from our present point of view.
Why are musical tones in a certain order and rhythm pleasurable? asked Darwin in The Descent of Man, and he concluded that the question was insoluble. We see that, in reality, whatever the ultimate answer may be, the immediate reason is quite simple. Pleasure is a condition of slight and diffused stimulation, in which the heart and breathing are faintly excited, the neuro-muscular system receives additional tone, the viscera gently stirred, the skin activity increased; and certain combinations of musical notes and intervals act as a physiological stimulus in producing these effects.[107]
Among animals of all kinds, from insects upward, this physiological action appears to exist, for among nearly all of them certain sounds are agreeable and attractive, and other sounds indifferent and disagreeable. It appears that insects of quite different genera show much appreciation of the song of the Cicada.[108] Birds show intense interest in the singing of good performers even of other species. Experiments among a variety of animals in the Zoological Gardens with performances on various instruments showed that with the exception of seals none were indifferent, and all felt a discord as offensive. Many animals showed marked likes and dislikes; thus, a tiger, who was obviously soothed by the violin, was infuriated by the piccolo; the violin and the flute were preferred by most animals.[109]
Most persons have probably had occasion to observe the susceptibility of dogs to music. It may here suffice to give one personal observation. A dog (of mixed breed, partly collie), very well known to me, on hearing a nocturne of Chopin, whined and howled, especially at the more pathetic pa.s.sages, once or twice catching and drawing out the actual note played; he panted, walked about anxiously, and now and then placed his head on the player"s lap. When the player proceeded to a more cheerful piece by Grieg, the dog at once became indifferent, sat down, yawned, and scratched himself; but as soon as the player returned once more to the nocturne the dog at once repeated his accompaniment.
There can be no doubt that among a very large number of animals of most various cla.s.ses, more especially among insects and birds, the attraction of music is supported and developed on the basis of s.e.xual attraction, the musical notes emitted serving as a s.e.xual lure to the other s.e.x. The evidence on this point was carefully investigated by Darwin on a very wide basis.[110] It has been questioned, some writers preferring to adopt the view of Herbert Spencer,[111] that the singing of birds is due to "overflow of energy," the relation between courtship and singing being merely "a relation of concomitance." This view is no longer tenable; whatever the precise origin of the musical notes of animals may be,-and it is not necessary to suppose that s.e.xual attraction had a large part in their first rudimentary beginnings,-there can now be little doubt that musical sounds, and, among birds, singing, play a very large part indeed in bringing the male and the female together.[112] Usually, it would appear, it is the performance of the male that attracts the female; it is only among very simple and primitive musicians, like some insects, that the female thus attracts the male.[113] The fact that it is nearly always one s.e.x only that is thus musically gifted should alone have sufficed to throw suspicion on any but a s.e.xual solution of this problem of animal song.
It is, however, an exceedingly remarkable fact that, although among insects and lower vertebrates the s.e.xual influence of music is so large, and although among mammals and predominantly in man the emotional and aesthetic influence of music is so great, yet neither in man nor any of the higher mammals has music been found to exert a predominant s.e.xual influence, or even in most cases any influence at all. Darwin, while calling attention to the fact that the males of most species of mammals use their vocal powers chiefly, and sometimes exclusively, during the breeding-season, adds that "it is a surprising fact that we have not as yet any good evidence that these organs are used by male mammals to charm the female."[114] From a very different standpoint, Fere, in studying the pathology of the human s.e.xual instinct in the light of a very full knowledge of the available evidence, states that he knows of no detailed observations showing the existence of any morbid s.e.xual perversions based on the sense of hearing, either in reference to the human voice or to instrumental music.[115]
When, however, we consider that not only in the animals most nearly related to man, but in man himself, the larynx and the voice undergo a marked s.e.xual differentiation at p.u.b.erty, it is difficult not to believe that this change has an influence on s.e.xual selection and s.e.xual psychology. At p.u.b.erty there is a slight hyperaemia of the larynx, accompanied by rapid development alike of the larynx itself and of the vocal cords, which become larger and thicker, while there is an a.s.sociated change in the voice, which deepens. All these changes are very slight in girls, but very p.r.o.nounced in boys, whose voices are said to "break" and then become lower by at least an octave. The feminine larynx at p.u.b.erty only increases in the proportion of 5 to 7, but the masculine larynx in the proportion of 5 to 10. The direct dependence of this change on the general s.e.xual development is shown not merely by its occurrence at p.u.b.erty, but by the fact that in eunuchs in whom the t.e.s.t.i.c.l.es have been removed before p.u.b.erty the voice retains its childlike qualities.[116]
As a matter of fact, I believe that we may attach a considerable degree of importance to the voice and to music generally as a method of s.e.xual appeal. On this point I agree with Moll, who remarks that "the sense of hearing here plays a considerable part, and the stimulation received through the ears is much larger than is usually believed."[117] I am not, however, inclined to think that this influence is considerable in its action on men, although Mantegazza remarks, doubtless with a certain truth, that "some women"s voices cannot be heard with impunity." It is true that the ancients deprecated the s.e.xual or at all events the effeminating influence of some kinds of music, but they seem to have regarded it as sedative rather than stimulating; the kind of music they approved of as martial and stimulating was the kind most likely to have s.e.xual effects in predisposed persons.
The Chinese and the Greeks have more especially insisted on the ethical qualities of music and on its moralizing and demoralizing effects. Some three thousand years ago, it is stated, a Chinese emperor, believing that only they who understood music are capable of governing, distributed administrative functions in accordance with this belief. He acted entirely in accordance with Chinese morality, the texts of Confucianism (see translations in the "Sacred Books of the East Series") show clearly that music and ceremony (or social ritual in a wide sense) are regarded as the two main guiding influences of life-music as the internal guide, ceremony as the external guide, the former being looked upon as the more important.
Among the Greeks Menander said that to many people music is a powerful stimulant to love. Plato, in the third book of the Republic, discusses what kinds of music should be encouraged in his ideal state. He does not clearly state that music is ever a s.e.xual stimulant, but he appears to a.s.sociate plaintive music (mixed Lydian and Hypolydian) with drunkenness, effeminacy, and idleness and considers that such music is "useless even to women that are to be virtuously given, not to say to men." He only admits two kinds of music: one violent and suited to war, the other tranquil and suited to prayer or to persuasion. He sets out the ethical qualities of music with a thoroughness which almost approaches the great Chinese philosopher: "On these accounts we attach such importance to a musical education, because rhythm and harmony sink most deeply into the recesses of the soul, and take most powerful hold of it, bringing gracefulness in their train, and making a man graceful if he be rightly nurtured, ... leading him to commend beautiful objects, and gladly receive them into his soul, and feed upon them, and grow to be n.o.ble and good." Plato is, however, by no means so consistent and thorough as the Chinese moralist, for having thus a.s.serted that it is the influence of music which molds the soul into virtue, he proceeds to destroy his position with the statement that "we shall never become truly musical until we know the essential forms of temperance and courage and liberality and munificence," thus moving in a circle. It must be added that the Greek conception of music was very comprehensive and included poetry.
Aristotle took a wider view of music than Plato and admitted a greater variety of uses for it. He was less anxious to exclude those uses which were not strictly ethical. He disapproved, indeed, of the Phrygian harmony as the expression of Bacchic excitement. He accepts, however, the function of music as a ???a?s?? of emotion, a notion which is said to have originated with the Pythagoreans. (For a discussion of Aristotle"s views on music, see W. L. Newman, The Politics of Aristotle, vol. i, pp. 359-369.)
Athenaeus, in his frequent allusions to music, attributes to it many intellectual and emotional properties (e.g., Book XIV, Chapter XXV) and in one place refers to "melodies inciting to lawless indulgence" (Book XIII, Chapter LXXV).
