Leonardo da Vinci Part 3

Whoever works as an artist certainly feels as a father to his works. The identification with his father had a fateful result in Leonardo's works of art. He created them and then troubled himself no longer about them, just as his father did not trouble himself about him. The later worriments of his father could change nothing in this compulsion, as the latter originated from the impressions of the first years of childhood, and the repression having remained unconscious was incorrigible through later experiences.

At the time of the Renaissance, and even much later, every artist was in need of a gentleman of rank to act as his benefactor. This patron was wont to give the artist commissions for work and entirely controlled his destiny. Leonardo found his patron in Lodovico Sforza, nicknamed Il Moro, a man of high aspirations, ostentations, diplomatically astute, but of an unstable and unreliable character. In his court in Milan, Leonardo spent the best period of his life, while in his service he evinced his most uninhibited productive activity as is evidenced in The Last Supper, and in the equestrian statue of Francesco Sforza. He left Milan before the catastrophe struck Lodovico Moro, who died a prisoner in a French prison. When the news of his benefactor's fate reached Leonardo he made the following entry in his diary: "The duke has lost state, wealth, and liberty, not one of his works will be finished by himself."[68] It is remarkable and surely not without significance that he here raises the same reproach to his benefactor that posterity was to apply to him, as if he wanted to lay the responsibility to a person who subst.i.tuted his father-series, for the fact that he himself left his works unfinished. As a matter of fact he was not wrong in what he said about the Duke.

However, if the imitation of his father hurt him as an artist, his resistance against the father was the infantile determinant of his perhaps equally vast accomplishment as an artist. According to Merejkowski's beautiful comparison he was like a man who awoke too early in the darkness, while the others were all still asleep. He dared utter this bold principle which contains the justification for all independent investigation: _"Chi dispute allegando l'autorita non adopra l'ingegno ma piuttosto la memoria"_ (Whoever refers to authorities in disputing ideas, works with his memory rather than with his reason).[69] Thus he became the first modern natural philosopher, and his courage was rewarded by an abundance of cognitions and suggestions; since the Greek period he was the first to investigate the secrets of nature, relying entirely on his observation and his own judgment. But when he learned to depreciate authority and to reject the imitation of the "ancients" and constantly pointed to the study of nature as the source of all wisdom, he only repeated in the highest sublimation attainable to man, which had already obtruded itself on the little boy who surveyed the world with wonder. To retranslate the scientific abstractions into concrete individual experiences, we would say that the "ancients" and authority only corresponded to the father, and nature again became the tender mother who nourished him. While in most human beings to-day, as in primitive times, the need for a support of some authority is so imperative that their world becomes shaky when their authority is menaced, Leonardo alone was able to exist without such support; but that would not have been possible had he not been deprived of his father in the first years of his life. The boldness and independence of his later scientific investigation presupposes that his infantile s.e.xual investigation was not inhibited by his father, and this same spirit of scientific independence was continued by his withdrawing from s.e.x.

If any one like Leonardo escapes in his childhood his father's intimidation and later throws off the shackles of authority in his scientific investigation, it would be in gross contradiction to our expectation if we found that this same man remained a believer and unable to withdraw from dogmatic religion. Psychoa.n.a.lysis has taught us the intimate connection between the father complex and belief in G.o.d, and daily demonstrates to us how youthful persons lose their religious belief as soon as the authority of the father breaks down. In the parental complex we thus recognize the roots of religious need; the almighty, just G.o.d, and kindly nature appear to us as grand sublimations of father and mother, or rather as revivals and restorations of the infantile conceptions of both parents. Religiousness is biologically traced to the long period of helplessness and need of help of the little child. When the child grows up and realizes his loneliness and weakness in the presence of the great forces of life, he perceives his condition as in childhood and seeks to disavow his despair through a regressive revival of the protecting forces of childhood.

It does not seem that Leonardo's life disproves this conception of religious belief. Accusations charging him with irreligiousness, which in those times was equivalent to renouncing Christianity, were brought against him already in his lifetime, and were clearly described in the first biography given by Vasari.[70] In the second edition of his Vite (1568) Vasari left out this observation. In view of the extraordinary sensitiveness of his age in matters of religion it is perfectly comprehensible to us why Leonardo refrained from directly expressing his position to Christianity in his notes. As investigator he did not permit himself to be misled by the account of the creation of the holy scriptures; for instance, he disputed the possibility of a universal flood, and in geology he was as unscrupulous in calculating with hundred thousands of years as modern investigators.

Among his "prophecies" one finds some things that would perforce offend the sensitive feelings of a religious Christian, e.g. Praying to the images of Saints, reads as follows:[71]

"People talk to people who perceive nothing, who have open eyes and see nothing; they shall talk to them and receive no answer; they shall adore those who have ears and hear nothing; they shall burn lamps for those who do not see."

Or: Concerning mourning on Good Friday (p. 297):

"In all parts of Europe great peoples will bewail the death of one man who died in the Orient."

It was a.s.serted of Leonardo's art that he took away the last remnant of religious attachment from the holy figures and put them into human form in order to depict in them great and beautiful human feelings. m.u.t.h.e.r praises him for having overcome the feeling of decadence, and for having returned to man the right of sensuality and pleasurable enjoyment. The notices which show Leonardo absorbed in fathoming the great riddles of nature do not lack any expressions of admiration for the creator, the last cause of all these wonderful secrets, but nothing indicates that he wished to hold any personal relation to this divine force. The sentences which contain the deep wisdom of his last years breathe the resignation of the man who subjects himself to the laws of nature and expects no alleviation from the kindness or grace of G.o.d. There is hardly any doubt that Leonardo had vanquished dogmatic as well as personal religion, and through his work of investigation he had withdrawn far from the world aspect of the religious Christian.

From our views mentioned before in the development of the infantile psychic life, it becomes clear that also Leonardo's first investigations in childhood occupied themselves with the problems of s.e.xuality. But he himself betrays it to us through a transparent veil, in that he connects his impulse to investigate with the vulture phantasy, and in emphasizing the problem of the flight of the bird as one whose elaboration devolved upon him through special concatenations of fate. A very obscure as well as a prophetically sounding pa.s.sage in his notes dealing with the flight of the bird demonstrates in the nicest way with how much affective interest he clung to the wish that he himself should be able to imitate, the art of flying: "The human bird shall take his first flight, filling the world with amazement, all writings with his fame, and bringing eternal glory to the nest whence he sprang." He probably hoped that he himself would sometimes be able to fly, and we know from the wish fulfilling dreams of people what bliss one expects from the fulfillment of this hope.

But why do so many people dream that they are able to fly?

Psychoa.n.a.lysis answers this question by stating that to fly or to be a bird in the dream is only a concealment of another wish, to the recognition of which one can reach by more than one linguistic or objective bridge. When the inquisitive child is told that a big bird like the stork brings the little children, when the ancients have formed the phallus winged, when the popular designation of the s.e.xual activity of man is expressed in German by the word "to bird" (vogeln), when the male member is directly called _l'uccello_ (bird) by the Italians, all these facts are only small fragments from a large collection which teaches us that the wish to be able to fly signifies in the dream nothing more or less than the longing for the ability of s.e.xual accomplishment. This is an early infantile wish. When the grown-up recalls his childhood it appears to him as a happy time in which one is happy for the moment and looks to the future without any wishes, it is for this reason that he envies children. But if children themselves could inform us about it they would probably give different reports. It seems that childhood is not that blissful Idyl into which we later distort it, that on the contrary children are lashed through the years of childhood by the wish to become big, and to imitate the grown ups.

This wish instigates all their playing. If in the course of their s.e.xual investigation children feel that the grown up knows something wonderful in the mysterious and yet so important realm, what they are prohibited from knowing or doing, they are seized with a violent wish to know it, and dream of it in the form of flying, or prepare this disguise of the wish for their later flying dreams. Thus aviation, which has attained its aim in our times, has also its infantile erotic roots.

By admitting that he entertained a special personal relation to the problem of flying since his childhood, Leonardo bears out what we must a.s.sume from our investigation of children of our times, namely, that his childhood investigation was directed to s.e.xual matters. At least this one problem escaped the repression which has later estranged him from s.e.xuality. From childhood until the age of perfect intellectual maturity this subject, slightly varied, continued to hold his interest, and it is quite possible that he was as little successful in his cherished art in the primary s.e.xual sense as in his desires for mechanical matters, that both wishes were denied to him.

As a matter of fact the great Leonardo remained infantile in some ways throughout his whole life; it is said that all great men retain something of the infantile. As a grown up he still continued playing, which sometimes made him appear strange and incomprehensible to his contemporaries. When he constructed the most artistic mechanical toys for court festivities and receptions we are dissatisfied thereby because we dislike to see the master waste his power on such petty stuff. He himself did not seem averse to giving his time to such things. Vasari reports that he did similar things even when not urged to it by request: "There (in Rome) he made a doughy ma.s.s out of wax, and when it softened he formed thereof very delicate animals filled with air; when he blew into them they flew in the air, and when the air was exhausted they fell to the ground. For a peculiar lizard caught by the wine-grower of Belvedere Leonardo made wings from skin pulled off from other lizards, which he filled with mercury so that they moved and trembled when it walked; he then made for it eyes, a beard and horns, tamed it and put it in a little box and terrified all his friends with it."[72] Such playing often served him as an expression of serious thoughts: "He had often cleaned the intestines of a sheep so well that one could hold them in the hollow of the hand; he brought them into a big room, and attached them to a blacksmith's bellows which he kept in an adjacent room, he then blew them up until they filled up the whole room so that everybody had to crowd into a corner. In this manner he showed how they gradually became transparent and filled up with air, and as they were at first limited to very little s.p.a.ce and gradually became more and more extended in the big room, he compared them to a genius."[73] His fables and riddles evince the same playful pleasure in harmless concealment and artistic investment, the riddles were put into the form of prophecies; almost all are rich in ideas and to a remarkable degree devoid of wit.

The plays and jumps which Leonardo allowed his phantasy have in some cases quite misled his biographers who misunderstood this part of his nature. In Leonardo's Milanese ma.n.u.scripts one finds, for example, outlines of letters to the "Diodario of Sorio (Syria), viceroy of the holy Sultan of Babylon," in which Leonardo presents himself as an engineer sent to these regions of the Orient in order to construct some works. In these letters he defends himself against the reproach of laziness, he furnishes geographical descriptions of cities and mountains, and finally discusses a big elementary event which occurred while he was there.[74]

In 1881, J. P. Richter had endeavored to prove from these doc.u.ments that Leonardo made these traveler's observations when he really was in the service of the Sultan of Egypt, and that while in the Orient he embraced the Mohammedan religion. This sojourn in the Orient should have taken place in the time of 1483, that is, before he removed to the court of the Duke of Milan. However, it was not difficult for other authors to recognize the ill.u.s.trations of this supposed journey to the Orient as what they really were, namely, phantastic productions of the youthful artist which he created for his own amus.e.m.e.nt, and in which he probably brought to expression his wishes to see the world and experience adventures.

A phantastic formation is probably also the "Academia Vinciana," the acceptance of which is due to the existence of five or six most clever and intricate emblems with the inscription of the Academy. Vasari mentions these drawings but not the Academy.[75] Muntz who placed such ornament on the cover of his big work on Leonardo belongs to the few who believe in the reality of an "Academia Vinciana."

It is probable that this impulse to play disappeared in Leonardo's maturer years, that it became discharged in the investigating activity which signified the highest development of his personality. But the fact that it continued so long may teach us how slowly one tears himself away from his infantilism after having enjoyed in his childhood supreme erotic happiness which is later unattainable.

VI

It would be futile to delude ourselves that at present, readers find every pathography unsavory. This att.i.tude is excused with the reproach that from a pathographic elaboration of a great man one never obtains an understanding of his importance and his attainments, that it is therefore useless mischief to study in him things which could just as well be found in the first comer. However, this criticism is so clearly unjust that it can only be grasped when viewed as a pretext and a disguise for something. As a matter of fact pathography does not aim at making comprehensible the attainments of the great man; no one should really be blamed for not doing something which one never promised. The real motives for the opposition are quite different. One finds them when one bears in mind that biographers are fixed on their heroes in quite a peculiar manner. Frequently they take the hero as the object of study because, for reasons of their personal emotional life, they bear him a special affection from the very outset. They then devote themselves to a work of idealization which strives to enroll the great men among their infantile models, and to revive through him, as it were, the infantile conception of the father. For the sake of this wish they wipe out the individual features in his physiognomy, they rub out the traces of his life's struggle with inner and outer resistances, and do not tolerate in him anything of human weakness or imperfection; they then give us a cold, strange, ideal form instead of the man to whom we could feel distantly related. It is to be regretted that they do this, for they thereby sacrifice the truth to an illusion, and for the sake of their infantile phantasies they let slip the opportunity to penetrate into the most attractive secrets of human nature.[76]

Leonardo himself, judging from his love for the truth and his inquisitiveness, would have interposed no objections to the effort of discovering the determinations of his psychic and intellectual development from the trivial peculiarities and riddles of his nature. We respect him by learning from him. It does no injury to his greatness to study the sacrifices which his development from the child must have entailed, and to the compile factors which have stamped on his person the tragic feature of failure.

Let us expressly emphasize that we have never considered Leonardo as a neurotic or as a "nervous person" in the sense of this awkward term.

Whoever takes it amiss that we should even dare apply to him viewpoints gained from pathology, still clings to prejudices which we have at present justly given up. We no longer believe that health and disease, normal and nervous, are sharply distinguished from each other, and that neurotic traits must be judged as proof of general inferiority. We know to-day that neurotic symptoms are subst.i.tutive formations for certain repressive acts which have to be brought about in the course of our development from the child to the cultural man, that we all produce such subst.i.tutive formations, and that only the amount, intensity, and distribution of these subst.i.tutive formations justify the practical conception of illness and the conclusion of const.i.tutional inferiority.

Following the slight signs in Leonardo's personality we would place him near that neurotic type which we designate as the "compulsive type," and we would compare his investigation with the "reasoning mania" of neurotics, and his inhibitions with the so-called "abulias" of the latter.

The object of our work was to explain the inhibitions in Leonardo's s.e.xual life and in his artistic activity. For this purpose we shall now sum up what we could discover concerning the course of his psychic development.

We were unable to gain any knowledge about his hereditary factors, on the other hand we recognize that the accidental circ.u.mstances of his childhood produced a far reaching disturbing effect. His illegitimate birth deprived him of the influence of a father until perhaps his fifth year, and left him to the tender seduction of a mother whose only consolation he was. Having been kissed by her into s.e.xual prematurity, he surely must have entered into a phase of infantile s.e.xual activity of which only one single manifestation was definitely evinced, namely, the intensity of his infantile s.e.xual investigation. The impulse for looking and inquisitiveness were most strongly stimulated by his impressions from early childhood; the enormous mouth-zone received its accentuation which it had never given up. From his later contrasting behavior, as the exaggerated sympathy for animals, we can conclude that this infantile period did not lack in strong s.a.d.i.s.tic traits.

An energetic s.h.i.+ft of repression put an end to this infantile excess, and established the dispositions which became manifest in the years of p.u.b.erty. The most striking result of this transformation was a turning away from all gross sensual activities. Leonardo was able to lead a life of abstinence and made the impression of an as.e.xual person. When the floods of p.u.b.escent excitement came over the boy they did not make him ill by forcing him to costly and harmful subst.i.tutive formations; owing to the early preference for s.e.xual inquisitiveness, the greater part of the s.e.xual needs could be sublimated into a general thirst after knowledge and so elude repression. A much smaller portion of the libido was applied to s.e.xual aims, and represented the stunted s.e.xual life of the grown up. In consequence of the repression of the love for the mother this portion a.s.sumed a h.o.m.os.e.xual att.i.tude and manifested itself as ideal love for boys. The fixation on the mother, as well as the happy reminiscences of his relations with her, was preserved in his unconscious but remained for the time in an inactive state. In this manner the repression, fixation, and sublimation partic.i.p.ated in the disposal of the contributions which the s.e.xual impulse furnished to Leonardo's psychic life.

From the obscure age of boyhood Leonardo appears to us as an artist, a painter, and sculptor, thanks to a specific talent which was probably enforced by the early awakening of the impulse for looking in the first years of childhood. We would gladly report in what way the artistic activity depends on the psychic primitive forces were it not that our material is inadequate just here. We content ourselves by emphasizing the fact, concerning which hardly any doubt still exists, that the productions of the artist give outlet also to his s.e.xual desire, and in the case of Leonardo we can refer to the information imparted by Vasari, namely, that heads of laughing women and pretty boys, or representations of his s.e.xual objects, attracted attention among his first artistic attempts. It seems that during his flouris.h.i.+ng youth Leonardo at first worked in an uninhibited manner. As he took his father as a model for his outer conduct in life, he pa.s.sed through a period of manly creative power and artistic productivity in Milan, where favored by fate he found a subst.i.tute for his father in the duke Lodovico Moro. But the experience of others was soon confirmed in him, to wit, that the almost complete suppression of the real s.e.xual life does not furnish the most favorable conditions for the activity of the sublimated s.e.xual strivings. The figurativeness of his s.e.xual life a.s.serted itself, his activity and ability to quick decisions began to weaken, the tendency to reflection and delay was already noticeable as a disturbance in The Holy Supper, and with the influence of the technique determined the fate of this magnificent work. Slowly a process developed in him which can be put parallel only to the regressions of neurotics. His development at p.u.b.erty into the artist was outstripped by the early infantile determinant of the investigator, the second sublimation of his erotic impulses turned back to the primitive one which was prepared at the first repression. He became an investigator, first in service of his art, later independently and away from his art. With the loss of his patron, the subst.i.tute for his father, and with the increasing difficulties in his life, the regressive displacement extended in dimension. He became _"impacientissimo al pennello"_ (most impatient with the brush) as reported by a correspondent of the countess Isabella d'Este who desired to possess at any cost a painting from his hand.[77]

His infantile past had obtained control over him. The investigation, however, which now took the place of his artistic production, seems to have born certain traits which betrayed the activity of unconscious impulses; this was seen in his insatiability, his regardless obstinacy, and in his lack of ability to adjust himself to actual conditions.

At the summit of his life, in the age of the first fifties, at a time when the s.e.x characteristics of the woman have already undergone a regressive change, and when the libido in the man not infrequently ventures into an energetic advance, a new transformation came over him.

Still deeper strata of his psychic content became active again, but this further regression was of benefit to his art which was in a state of deterioration. He met the woman who awakened in him the memory of the happy and sensuously enraptured smile of his mother, and under the influence of this awakening he acquired back the stimulus which guided him in the beginning of his artistic efforts when he formed the smiling woman. He painted Monna Lisa, Saint Anne, and a number of mystic pictures which were characterized by the enigmatic smile. With the help of his oldest erotic feelings he triumphed in conquering once more the inhibition in his art. This last development faded away in the obscurity of the approaching old age. But before this his intellect rose to the highest capacity of a view of life, which was far in advance of his time.

In the preceding chapters I have shown what justification one may have for such representation of Leonardo's course of development, for this manner of arranging his life and explaining his wavering between art and science. If after accomplis.h.i.+ng these things I should provoke the criticism from even friends and adepts of psychoa.n.a.lysis, that I have only written a psychoa.n.a.lytic romance, I should answer that I certainly did not overestimate the reliability of these results. Like others I succ.u.mbed to the attraction emanating from this great and mysterious man, in whose being one seems to feel powerful propelling pa.s.sions, which after all can only evince themselves so remarkably subdued.

But whatever may be the truth about Leonardo's life we cannot relinquish our effort to investigate it psychoa.n.a.lytically before we have finished another task. In general we must mark out the limits which are set up for the working capacity of psychoa.n.a.lysis in biography so that every omitted explanation should not be held up to us as a failure.

Psychoa.n.a.lytic investigation has at its disposal the data of the history of the person's life, which on the one hand consists of accidental events and environmental influences, and on the other hand of the reported reactions of the individual. Based on the knowledge of psychic mechanisms it now seeks to investigate dynamically the character of the individual from his reactions, and to lay bare his earliest psychic motive forces as well as their later transformations and developments.

If this succeeds then the reaction of the personality is explained through the cooperation of const.i.tutional and accidental factors or through inner and outer forces. If such an undertaking, as perhaps in the case of Leonardo, does not yield definite results then the blame for it is not to be laid to the faulty or inadequate psychoa.n.a.lytic method, but to the vague and fragmentary material left by tradition about this person. It is, therefore, only the author who forced psychoa.n.a.lysis to furnish an expert opinion on such insufficient material, who is to be held responsible for the failure.

However, even if one had at his disposal a very rich historical material and could manage the psychic mechanism with the greatest certainty, a psychoa.n.a.lytic investigation could not possibly furnish the definite view, if it concerns two important questions, that the individual could turn out only so and not differently. Concerning Leonardo we had to represent the view that the accident of his illegitimate birth and the pampering of his mother exerted the most decisive influence on his character formation and his later fate, through the fact that the s.e.xual repression following this infantile phase caused him to sublimate his libido into a thirst after knowledge, and thus determined his s.e.xual inactivity for his entire later life. The repression, however, which followed the first erotic gratification of childhood did not have to take place, in another individual it would perhaps not have taken place or it would have turned out not nearly as profuse. We must recognize here a degree of freedom which can no longer be solved psychoa.n.a.lytically.

One is as little justified in representing the issue of this s.h.i.+ft of repression as the only possible issue. It is quite probable that another person would not have succeeded in withdrawing the main part of his libido from the repression through sublimation into a desire for knowledge; under the same influences as Leonardo another person might have sustained a permanent injury to his intellectual work or an uncontrollable disposition to compulsion neurosis. The two characteristics of Leonardo which remained unexplained through psychoa.n.a.lytic effort are first, his particular tendency to repress his impulses, and second, his extraordinary ability to sublimate the primitive impulses.

The impulses and their transformations are the last things that psychoa.n.a.lysis can discern. Henceforth it leaves the place to biological investigation. The tendency to repression, as well as the ability to sublimate, must be traced back to the organic bases of the character, upon which alone the psychic structure springs up. As artistic talent and productive ability are intimately connected with sublimation we have to admit that also the nature of artistic attainment is psychoa.n.a.lytically inaccessible to us. Biological investigation of our time endeavors to explain the chief traits of the organic const.i.tution of a person through the fusion of male and female predispositions in the material sense; Leonardo's physical beauty as well as his left-handedness furnish here some support. However, we do not wish to leave the ground of pure psychologic investigation. Our aim remains to demonstrate the connection between outer experiences and reactions of the person over the path of the activity of the impulses. Even if psychoa.n.a.lysis does not explain to us the fact of Leonardo's artistic accomplishment, it still gives us an understanding of the expressions and limitations of the same. It does seem as if only a man with Leonardo's childhood experiences could have painted Monna Lisa and Saint Anne, and could have supplied his works with that sad fate and so obtain unheard of fame as a natural historian; it seems as if the key to all his attainments and failures was hidden in the childhood phantasy of the vulture.

But may one not take offense at the results of an investigation which concede to the accidents of the parental constellation so decisive an influence on the fate of a person, which, for example, subordinates Leonardo's fate to his illegitimate birth and to the sterility of his first step-mother Donna Albiera? I believe that one has no right to feel so; if one considers accident as unworthy of determining our fate, it is only a relapse to the pious aspect of life, the overcoming of which Leonardo himself prepared when he put down in writing that the sun does not move. We are naturally grieved over the fact that a just G.o.d and a kindly providence do not guard us better against such influences in our most defenseless age. We thereby gladly forget that as a matter of fact everything in our life is accident from our very origin through the meeting of spermatozoa and ovum, accident, which nevertheless partic.i.p.ates in the lawfulness and fatalities of nature, and lacks only the connection to our wishes and illusions. The division of life's determinants into the "fatalities" of our const.i.tution and the "accidents" of our childhood may still be indefinite in individual cases, but taken altogether one can no longer entertain any doubt about the importance of precisely our first years of childhood. We all still show too little respect for nature, which in Leonardo's deep words recalling Hamlet's speech _"is full of infinite reasons which never appeared in experience."_[78] Every one of us human beings corresponds to one of the infinite experiments in which these "reasons of nature"

force themselves into experience.
