... men are not gentle creatures, who want to be loved, who at the most can defend themselves if they are attacked; they are, on the contrary, creatures among whose instinctual endowments is to be reckoned a powerful share of aggressiveness. As a result, their neighbour is for them not only a potential helper or sexual object, but also someone who tempts them to satisfy their aggressiveness on him, to exploit his capacity for work without compensation, to use him sexually without his consent, to seize his possessions, to humiliate him, to cause him pain, to torture and to kill him. Homo homini lupus [man is wolf to man]. Who in the face of all his experience of life and of history, will have the courage to dispute this assertion? As a rule this cruel aggressiveness waits for some provocation or puts itself at the service of some other purpose, whose goal might also have been reached by milder measures. In circumstances that are favorable to it, when the mental counter-forces which ordinarily inhibit it are out of action, it also manifests itself spontaneously and reveals man as a savage beast to whom consideration towards his own kind is something alien. Anyone who calls to mind the atrocities committed during the racial migrations or the invasions of the Huns, or by the people known as Mongols under Jenghiz Khan and Tamerlane, or at the capture of Jerusalem by the pious Crusaders, or even, indeed, the horrors of the recent World War -- anyone who calls these things to mind will have to bow humbly before the truth of this view.
The existence of this inclination to aggression, which we can detect in ourselves and justly assume to be present in others, is the factor which disturbs our relations with our neighbor and which forces civilization into such a high expenditure [of energy]. In consequence of this primary mutual hostility of human beings, civilized society is perpetually threatened with disintegration. The interest of work in common would not hold it together; instinctual passions are stronger than reasonable interests. Civilization has to use its utmost efforts in order to set limits to man's aggressive instincts and to hold the manifestations of hem in check by psychical reaction-formations. Hence, therefore, the use of methods intended to incite people into identifications and aim-inhibited relations of love, hence the restriction upon sexual life, and hence too the ideal's commandment to love one's neighbor as oneself -- a commandment which is really justified by the fact that nothing else runs so strongly counter to the original nature of man. In spite of every effort, these endeavors of civilization have not so far achieved very much. It hopes to prevent the crudest excesses of brutal violence by itself assuming the right to use violence against criminals, but the law is not able to lay hold of the more cautious and refined manifestations of human aggressiveness. The time comes when each one of us has to give up illusions the expectations which, in his youth. he pinned upon his fellow men, and when he may learn how much difficulty and pain has been added to his life by their ill-will. At the same time, it would be unfair to reproach civilization with trying to eliminate strife and competition from human activity. These things are undoubtedly indispensable. But opposition is not necessarily enmity; it is merely misused and made occasion for enmity.
The communists believe they have found the path to deliverance from our evils. According to them, man is wholly good and as well-disposed to his neighbor; but the institution of private property has corrupted his nature. The ownership of private wealth gives the individual power, and waited the temptation to ill-treat his neighbor; while the man who is excluded from possession is bound to rebel in hostility against his oppressor. If private property were abolished, all wealth held in common, and everyone allowed to share in the enjoyment of it, ill-will and hostility would disappear among men. Since everyone's needs would be satisfied, no one would have any reason to regard another as his enemy; all would willingly undertake the work that was necessary. I have no concern with any economic criticisms of the communist system; I cannot inquire into whether the abolition of private property is expedient or advantageous. But I am able to recognize that the psychological premises on which the systems based are an untenable illusion. In abolishing private property we deprive the human love of aggression of one of its instruments, certainly a strong one, though certainly not the strongest; but we have in no way altered the differences in power and influence which are misused by aggressiveness, nor have we altered anything in its nature. Aggressiveness was not created by property. It reigned almost before property had given up its primal, anal form; it forms the basis of every relation of affection and love among people (with the single exception, perhaps, of the mother's relation to her male child). If we do away with personal rights over material wealth, there still remains prerogative in the field of sexual relationships, which is bound to become the source of the strongest dislike in the most violent hostility among men who in other respects are on an equal footing. If we were to remove this factor, too, by allowing complete freedom of sexual life and thus abolishing the family, the germ-cell of civilization, we cannot, it is true, easily foresee what new paths the development of civilization could take; but one thing we can expect, and that is that this indestructible feature of human nature will follow at there.
It is clearly not easy for man to give up the satisfaction of this inclination to aggression. They do not feel comfortable without it. The advantage which a comparatively small cultural group offers of allowing this instinct an outlet in the form of hostility against intruders is not to be despised. It is always possible to bind together a considerable number of people in love, so long as there are other people left over to receive the manifestations of their aggressiveness. I once discussed the phenomenon that is precisely communities with adjoining territories, and related to each other in other ways as well, who are engaged in constant feuds and in ridiculing each other -- like the Spaniards and Portuguese, for instance, the North Germans and South Germans, the English and Scotch, and so on. I gave this phenomenon the name of "the narcissism of minor differences", a name which does not do much to explain it. We can now see that it is a convenient and relatively harmless satisfaction of the inclination to aggression, by means of which cohesion between the members of the community is made easier. In this respect the Jewish people, scattered everywhere, have rendered most useful services to the civilizations of the countries that have been their hosts; but unfortunately all the massacres of the Jews in the Middle Ages did not suffice to make that period more peaceful and secure for their Christian fellows. When once the Apostle Paul had posited universal love between men as the foundation of his Christian community, extreme intolerance, part of Christendom towards those who remained outside its became the inevitable consequence. To the Romans, who had not founded their communal life as a State upon love, religious intolerance was something foreign, although with them religion was a concern of the State and the State was permeated by religion. Neither was it an unaccountable chance that the dream of a Germanic world-dominion called for anti-Semitism as its complement; and it is intelligible that the attempts to establish a new, communist civilization in Russia should find its psychological support in the persecution of the bourgeois. One only wonders, with concern, what the Soviets will do after they have wiped out their bourgeois.
Is Civilization imposes such great sacrifices not only on man's sexuality but on his aggressivity, we can understand better why it is hard for him to be happy in that civilization. In fact, primitive man was better off in knowing no restrictions of instinct. To counterbalance this, his prospects of enjoying this happiness for any length of time were very slender. Civilized man has exchanged a portion of his possibilities of happiness for a portion of security. We must not forget, however, that in the primal family only the head of it enjoyed this instinctual freedom; the rest lived in slavish suppression. In that primal period of civilization, the contrast between a minority who enjoyed the advantages of civilization and a majority who were robbed of those advantages was, therefore, carried to extremes. As regards the primitive peoples who exists to-day, careful researches have shown that their instinctual life is by no means to be envied for its freedom. It is subject to restrictions of a different kind but perhaps of greater severity than those attaching to modern civilized man.
When we justly find fault with the present state of our civilization for so inadequately fulfilling our demands for plan of life that shall make us happy, and for allowing the existence of so much suffering which could probably be avoided -- when, with unsparing criticism, we try to uncover the roots of its imperfection, we are undoubtedly exercising a proper right and are not showing ourselves enemies of civilization. We may expect gradually to carry through such alterations in our civilization as will better satisfy our needs and will escape our criticisms. But perhaps we may also familiarize ourselves with the idea that there are difficulties attaching to the nature of civilization which will not yield to any attempt at reform. Over and above the tasks of restricting the instincts, which we are prepared for, there forces itself on our notice the danger of a state of things which might be termed "the psychological poverty of groups". This danger is most threatening where the bonds of a society are chiefly constituted by the identification of its members with one another, while individuals of the leader type do not acquire the importance that should fall to them in the formation of a group. The present cultural state of America would give us a good opportunity for studying the damage to civilization which is us to be feared. But I shall avoid the temptation of entering upon a critique of American civilization; I do not wish to give an impression of wanting myself to employ American methods.
