In this post, International Portal resurfaces an exchange between two of the most prominent figures of the twentieth century who embarked on an epistolar conversation on the subject of ‘Why War’. Tasked by the League of Nations with investigating the main drivers of conflict, Albert Einstein reached out to Sigmund Freud, the father of psychoanalysis, for his views on the subject.

The exchange took place in 1931-1932, one year before the Nazi Party won the national election in Germany and Adolf Hitler became the Fuhrer that was to lead Germany and the world into chaos and destruction. Both of Jewish descent, in 1938 Sigmund Freud flew Austria to escape the Nazis, dying of cancer one year later in London, whereas Albert Einstein escaped in 1933, obtaining the US citizenship in 1940 and dying there in 1955.

A full transcript of their exchange is available here, and in this post International Portal brings you the key highlights of this debate, which raise points of utmost importance and relevance in an age characterised by the rollback of the supranational, the ascent of dangerous populisms, and the continued and in some areas renewed proliferation of weapons of mass destruction.

Einstein to Freud in his opening letter of July 1932:

This is the problem: Is there any way of delivering mankind from the menace of war? It is common knowledge that, with the advance of modern science, this issue has come to mean a matter of life and death for Civilization as we know it; nevertheless, for all the zeal displayed, every attempt at its solution has ended in a lamentable breakdown…

…How is it that these devices succeed so well in rousing men to such wild enthusiasm, even to sacrifice their lives? Only one answer is possible. Because man has within him a lust for hatred and destruction. In normal times this passion exists in a latent state, it emerges only in unusual circumstances; but it is a comparatively easy task to call it into play and raise it to the power of a collective psychosis. Here lies, perhaps, the crux of all the complex factors we are considering, an enigma that only the expert in the lore of human instincts can resolve

…And so we come to our last question. Is it possible to control man’s mental evolution so as to make him proof against the psychosis of hate and destructiveness? Here I am thinking by no means only of the so-called uncultured masses. Experience proves that it is rather the so-called “intelligentsia” that is most apt to yield to these disastrous collective suggestions…

…I know that in your writings we may find answers, explicit or implied, to all the issues of this urgent and absorbing problem. But it would be of the greatest service to us all were you to present the problem of world peace in the light of your most recent discoveries, for such a presentation well might blaze the trail for new and fruitful modes of action.”

Freud to Einstein in September 1932:

There is but one sure way of ending war and that is the establishment, by common consent, of a central control which shall have the last word in every conflict of interests. For this, two things are needed: first, the creation of such a supreme court of judicature; secondly, its investment with adequate executive force. Unless this second requirement be fulfilled, the first is unavailing. Obviously the League of Nations, acting as a Supreme Court, fulfills the first condition; it does not fulfill the second. It has no force at its disposal and can only get it if the members of the new body, its constituent nations, furnish it…

…You are amazed that it is so easy to infect men with the war fever, and you surmise that man has in him an active instinct for hatred and destruction, amenable to such stimulations. I entirely agree with you

We assume that human instincts are of two kinds: those that conserve and unify, which we call “erotic” (in the meaning Plato gives to Eros in his Symposium), or else “sexual” (explicitly extending the popular connotation of “sex”); and, secondly, the instincts to destroy and kill, which we assimilate as the aggressive or destructive instincts. These are, as you perceive, the well known opposites, Love and Hate, transformed into theoretical entities;…

…It seems that an instinct of either category can operate but rarely in isolation; it is always blended (“alloyed,” as we say) with a certain dosage of its opposite, which modifies its aim or even, in certain circumstances, is a prime condition of its attainment…

…Indeed, it might well be called the “death instinct”; whereas the erotic instincts vouch for the struggle to live on. The death instinct becomes an impulse to destruction when, with the aid of certain organs, it directs its action outward, against external objects. The living being, that is to say, defends its own existence by destroying foreign bodies. But, in one of its activities, the death instinct is operative within the living being…

…whereas the diversion of the destructive impulse toward the external world must have beneficial effects. Here is then the biological justification for all those vile, pernicious propensities which we are now combating

…The upshot of these observations, as bearing on the subject in hand, is that there is no likelihood of our being able to suppress humanity’s aggressive tendencies

…In any case, as you too have observed, complete suppression of man’s aggressive tendencies is not in issue; what we may try is to divert it into a channel other than that of warfare

…From our “mythology” of the instincts we may easily deduce a formula for an indirect method of eliminating war. If the propensity for war be due to the destructive instinct, we have always its counter-agent, Eros, to our hand. All that produces ties of sentiment between man and man must serve us as war’s antidote. These ties are of two kinds. First, such relations as those toward a beloved object, void though they be of sexual intent. The psychoanalyst need feel no compunction in mentioning “love” in this connection; religion uses the same language: Love thy neighbor as thyself. A pious injunction, easy to enounce, but hard to carry out! The other bond of sentiment is by way of identification. All that brings out the significant resemblances between men calls into play this feeling of community, identification, whereon is founded, in large measure, the whole edifice of human society…

…The cultural development of mankind (some, I know, prefer to call it civilization) has been in progress since immemorial antiquity. To this processus we owe all that is best in our composition, but also much that makes for human suffering. Its origins and causes are obscure, its issue is uncertain, but some of its characteristics are easy to perceive. It well may lead to the extinction of mankind, for it impairs the sexual function in more than one respect, and even today the uncivilized races and the backward classes of all nations are multiplying more rapidly than the cultured elements…

The psychic changes which accompany this process of cultural change are striking, and not to be gainsaid. They consist in the progressive rejection of instinctive ends and a scaling down of instinctive reactions

…On the psychological side two of the most important phenomena of culture are, firstly, a strengthening of the intellect, which tends to master our instinctive life, and, secondly, an introversion of the aggressive impulse, with all its consequent benefits and perils. Now war runs most emphatically counter to the psychic disposition imposed on us by the growth of culture; we are therefore bound to resent war, to find it utterly intolerable

How long have we to wait before the rest of men turn pacifist? Impossible to say, and yet perhaps our hope that these two factors–man’s cultural disposition and a well-founded dread of the form that future wars will take–may serve to put an end to war in the near future, is not chimerical.”
