maintenance of civilization even on such questionable grounds offers the prospect that with every new generation a more extensive transformation of impulses will pave the way for a better civilization.

These discussions have already afforded us the consolation that our mortification and painful disappointment on account of the uncivilized behavior of our fellow world citizens in this war were not justified. They rested upon an illusion to which we had succumbed. In reality they have not sunk as deeply as we feared because they never really rose as high as we had believed. The fact that states and races abolished their mutual ethical restrictions not unnaturally incited them to withdraw for a time from the existing pressure of civilization and to sanction a passing gratification of their suppressed impulses. In doing so their relative morality within their own national life probably suffered no rupture.

But we can still further deepen our understanding of the change which this war has brought about in our former compatriots and at the same time take warning not to be unjust to them. For psychic evolution shows a peculiarity which is not found in any other process of development. When a town becomes a city or a child grows into a man, town and child disappear in the city and in the man. Only memory can sketch in the old features in the new picture; in reality the old materials and forms have been replaced by new ones. It is different in the case of psychic evolution. One can describe this unique state of affairs only by saying that every previous stage of development is preserved next to the following one from which it has evolved; the succession stipulates a co-existence although the material in which the whole series of changes has taken place remains the same.

The earlier psychic state may not have manifested itself for years but nevertheless continues to exist to the extent that it may some day again become the form in which psychic forces express themselves, in fact the only form, as though all subsequent developments had been annulled and made regressive. This extraordinary plasticity of psychic development is not without limits as to its direction; one can describe it as a special capacity for retrograde action or regression, for it sometimes happens that a later and higher stage of development that has been abandoned cannot be attained again. But the primitive conditions can always be reconstructed; the primitive psyche is in the strictest sense indestructible.

The so-called mental diseases must make the impression on the layman of mental and psychic life fallen into decay. In reality the destruction concerns only later acquisitions and developments. The nature of mental diseases consists in the return to former states of the affective life and function. An excellent example of the plasticity of the psychic life is the state of sleep, which we all court every night.

Since we know how to interpret even the maddest and most confused dreams, we know that every time we go to sleep we throw aside our hard won morality like a garment in order to put it on again in the morning. This laying bare is, of course, harmless, because we are paralyzed and condemned to inactivity by the sleeping state.

Only the dream can inform us of the regression of our emotional life to an earlier stage of development. Thus, for instance, it is worthy of note that all our dreams are governed by purely egotistic motives. One of my English friends once presented this theory to a scientific meeting in America, whereupon a lady present made the remark that this might perhaps be true of Austrians, but she ventured to assert for herself and her friends that even in dreams they always felt altruistically. My friend, although himself a member of the English race, was obliged to contradict the lady energetically on the basis of his experience in dream analysis. The noble Americans are just as egotistic in their dreams as the Austrians.

The transformation of impulses upon which our cultural adaptability rests can therefore also be permanently or temporarily made regressive. Without doubt the influences of war belong to those forces which can create such regressions; we therefore need not deny cultural adaptibility to all those who at present are acting in such an uncivilized manner, and may expect that the refinement of their impulses will continue in more peaceful times.

But there is perhaps another symptom of our fellow citizens of the world which has caused us no less surprise and fear than this descent from former ethical heights which has been so painful to us. I mean the lack of insight that our greatest intellectual leaders have shown, their obduracy, their inaccessibility to the most impressive arguments, their uncritical credulity concerning the most contestable assertions. This certainly presents a sad picture, and I wish expressly to emphasize that I am by no means a blinded partisan who finds all the intellectual mistakes on one side. But this phenomenon is more easily explained and far less serious than the one which we have just considered. Students of human nature and philosophers have long ago taught us that we do wrong to value our intelligence as an independent force and to overlook its dependence upon our emotional life. According to their view our intellect can work reliably only when it is removed from the influence of powerful incitements; otherwise it acts simply as an instrument at the beck and call of our will and delivers the results which the will demands. Logical argumentation is therefore powerless against affective interests; that is why arguing with reasons which, according to Falstaff, are as common as blackberries, are so fruitless where our interests are concerned. Whenever possible psychoanalytic experience has driven home this assertion. It is in a position to prove every day that the cleverest people suddenly behave as unintelligently as defectives as soon as their understanding encounters emotional resistance, but that they regain their intelligence completely as soon as this resistance has been overcome. This blindness to logic which this war has so frequently conjured up in just our best fellow citizens, is therefore a secondary phenomenon, the result of emotional excitement and destined, we hope, to disappear simultaneously with it.

If we have thus come to a fresh understanding of our estranged fellow citizens we can more easily bear the disappointment which nations have caused us, for of them we must only make demands of a far more modest nature. They are perhaps repeating the development of the individual and at the present day still exhibit very primitive stages of development with a correspondingly slow progress towards the formation of higher unities. It is in keeping with this that the educational factor of an outer compulsion to morality, which we found so active in the individual, is barely perceptible in them. We had indeed hoped that the wonderful community of interests established by intercourse and the exchange of products would result in the beginning of such a compulsion, but it seems that nations obey their passions of the moment far more than their interests. At most they make use of their interests to justify the gratification of their passions.

It is indeed a mystery why the individual members of nations should disdain, hate, and abhor each other at all, even in times of peace. I do not know why it is. It seems as if all the moral achievements of the individual were obliterated in the case of a large number of people, not to mention millions, until only the most primitive, oldest, and most brutal psychic inhibitions remained.

Perhaps only later developments will succeed in changing these lamentable conditions. But a little more truthfulness and straightforward dealing on all sides, both in the relation of people towards each other and between themselves and
