We were unable to gain any knowledge about his hereditary factors, on

the other hand we recognize that the accidental circumstances 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 sexual prematurity,

he surely must have entered into a phase of infantile sexual activity of

which only one single manifestation was definitely evinced, namely, the

intensity of his infantile sexual 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 sadistic traits.

An energetic shift of repression put an end to this infantile excess,

and established the dispositions which became manifest in the years of

puberty. 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 asexual person. When the

floods of pubescent excitement came over the boy they did not make him

ill by forcing him to costly and harmful substitutive formations; owing

to the early preference for sexual inquisitiveness, the greater part of

the sexual needs could be sublimated into a general thirst after

knowledge and so elude repression. A much smaller portion of the libido

was applied to sexual aims, and represented the stunted sexual life of

the grown up. In consequence of the repression of the love for the

mother this portion assumed a homosexual attitude 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 participated in the

disposal of the contributions which the sexual 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 sexual 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 sexual objects, attracted attention among his first artistic

attempts. It seems that during his flourishing youth Leonardo at first

worked in an uninhibited manner. As he took his father as a model for

his outer conduct in life, he passed through a period of manly creative

power and artistic productivity in Milan, where favored by fate he found

a substitute 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 sexual life does not furnish the most

favorable conditions for the activity of the sublimated sexual

strivings. The figurativeness of his sexual life asserted 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

puberty 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 substitute 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 sex 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 accomplishing these things I should provoke the

criticism from even friends and adepts of psychoanalysis, that I have

only written a psychoanalytic romance, I should answer that I certainly

did not overestimate the reliability of these results. Like others I

succumbed to the attraction emanating from this great and mysterious

man, in whose being one seems to feel powerful propelling passions,

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 psychoanalytically before we have finished

another task. In general we must mark out the limits which are set up

for the working capacity of psychoanalysis in biography so that every

omitted explanation should not be held up to us as a failure.

Psychoanalytic 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 cooeperation of constitutional 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 psychoanalytic method,

but to the vague and fragmentary material left by tradition about this

person. It is, therefore, only the author who forced psychoanalysis 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

psychoanalytic 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 sexual

repression following this infantile phase caused him to sublimate his

libido into a thirst after knowledge, and thus determined his sexual

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 psychoanalytically.

One is as little justified in representing the issue of this shift 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

psychoanalytic 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

psychoanalysis 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

psychoanalytically inaccessible to us. Biological investigation of our

time endeavors to explain the chief traits of the organic constitution

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

psychoanalysis 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 God 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

participates 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 constitution 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.

[42] Leonardo thus behaves like one who was in the habit of making a

daily confession to another person whom he now replaced by his diary.

p. 309.

[47] Merejkowski 1. c.--As a disappointing illustration of the vagueness

of the information concerning Leonardo's intimate life, meager as it is,

I mention the fact that the same expense account is given by Solmi with

considerable variation (German translation, p. 104). The most serious

difference is the substitution of florins by soldi. One may assume that

in this account florins do not mean the old "gold florins," but those

used at a later period which amounted to 1-2/3 lira or 33-1/2

soldi.--Solmi represents Caterina as a servant who had taken care of

Leonardo's household for a certain time. The source from which the two

representations of this account were taken was not accessible to me.

[48] "Caterina came in July, 1493."

[49] The manner of expression through which the repressed libidio could

manifest itself in Leonardo, such as circumstantiality and marked

interest in money, belongs to those traits of character which emanate

from anal eroticism. Cf. Character und Analerotik in the second series

of my Sammlung zur Neurosenlehre, 1909, also Brill's Psychoanalysis, its

[59] The same is assumed by Merejkowski, who imagined a childhood for

Leonardo which deviates in the essential points from ours, drawn from

the results of the vulture phantasy. But if Leonardo himself had

displayed this smile, tradition hardly would have failed to report to us

this coincidence.

[65] I shall overlook a greater error committed by Leonardo in his

notice in that he gives his 77-year-old father 80 years.

in the presence of the Son of God, has made out of my cemetery a sewer."

[75] Besides, he lost some time in that he even made a drawing of a

braided cord in which one could follow the thread from one end to the

other, until it formed a perfectly circular figure; a very difficult and

beautiful drawing of this kind is engraved on copper, in the center of

it one can read the words: "Leonardus Vinci Academia" (p. 8).
