From Mein Kampf, Volume One, Chapter XI, Nation and Race
The mental qualities of the Jew have been schooled in the course of many centuries. Today he passes as ‘smart,’ and this in a certain sense he has been at all times. But his intelligence is not the result of his own development, but of visual instruction through foreigners. For the human mind cannot climb to the top without steps; for every step upward he needs the foundation of the past, and this in the comprehensive sense in which it can be revealed only in general culture. All thinking is based only in small part on man’s own knowledge, and mostly on the experience of the time that has preceded. The general cultural level provides the individual man, without his noticing it as a rule, with such a profusion of preliminary knowledge that, thus armed, he can more easily take further steps of his own. The boy of today, for example, grows up among a truly vast number of technical acquisitions of the last centuries, so that he takes for granted and no longer pays attention to much that a hundred years ago was a riddle to even the greatest minds, although for following and understanding our progress in the field in question it is of decisive importance to him. If a very genius from the twenties of the past century should suddenly leave his grave today, it would be harder for him even intellectually to find his way in the present era than for an average boy of fifteen today. For he would lack all the infinite preliminary education which our present contemporary unconsciously, so to speak, assimilates while growing up amidst the manifestations of our present general civilization.
For if the Jewish people’s instinct of self-preservation is not smaller but larger than that of other peoples, if his intellectual faculties can easily arouse the impression that they are equal to the intellectual gifts of other races, he lacks completely the most essential requirement for a cultured people, the idealistic attitude.
In the Jewish people the will to self-sacrifice does not go beyond the individual’s naked instinct of self-preservation. Their apparently great sense of solidarity is based on the very primitive herd instinct that is seen in many other living creatures in this world. It is a noteworthy fact that the herd instinct leads to mutual support only as long as a common danger makes this seem useful or inevitable. The same pack of wolves which has just fallen on its prey together disintegrates when hunger abates into its individual beasts. The same is true of horses which try to defend themselves against an assailant in a body, but scatter again as soon as the danger is past.
It is similar with the Jew. His sense of sacrifice is only apparent. It exists only as long as the existence of the individual makes it absolutely necessary. However, as soon as the common enemy is conquered, the danger threatening all averted and the booty hidden, the apparent harmony of the Jews among themselves ceases, again making way for their old causal tendencies. The Jew is only united when a common danger forces him to be or a common booty entices him; if these two grounds are lacking, the qualities of the crassest egoism come into their own, and in the twinkling of an eye the united people turns into a horde of rats, fighting bloodily among themselves.
If the Jews were alone in this world, they would stifle in filth and offal; they would try to get ahead of one another in hate-filled struggle and exterminate one another, in so far as the absolute absence of all sense of self-sacrifice, expressing itself in their cowardice, did not turn battle into comedy here too.
So it is absolutely wrong to infer any ideal sense of sacrifice in the Jews from the fact that they stand together in struggle, or, better expressed, in the plundering of their fellow men.
Here again the Jew is led by nothing but the naked egoism of the individual.
That is why the Jewish state-which should be the living organism for preserving and increasing a race-is completely unlimited as to territory. For a state formation to have a definite spatial setting always presupposes an idealistic attitude on the part of the state-race, and especially a correct interpretation of the concept of work. In the exact measure in which this attitude is lacking, any attempt at forming, even of preserving, a spatially delimited state fails. And thus the basis on which alone culture can arise is lacking.
Hence the Jewish people, despite all apparent intellectual qualities, is without any true culture, and especially without any culture of its own. For what sham culture the Jew today possesses is the property of other peoples, and for the most part it is ruined in his hands.
On this first and greatest lie, that the Jews are not a race but a religion, more and more lies are based in necessary consequence. Among them is the lie with regard to the language of the Jew. For him it is not a means for expressing his thoughts, but a means for concealing them. When he speaks French, he thinks Jewish, and while he turns out German verses, in his life he only expresses the nature of his nationality. As long as the Jew has not become the master of the other peoples, he must speak their languages whether he likes it or not, but as soon as they became his slaves, they would all have to learn a universal language (Esperanto, for instance!), so that by this additional means the Jews could more easily dominate them!
The best way to know the Jew is to study the road which he has taken within the body of other peoples in the course of the centuries. It suffices to follow this up in only one example, to arrive at the necessary realizations. As his development has always and at all times been the same, just as that of the peoples corroded by him has also been the same, it is advisable in such an examination to divide his development into definite sections which in this case for the sake of simplicity I designate alphabetically. The first Jews came to ancient Germany in the course of the advance of the Romans, and as always they came as merchants. In the storms of the migrations, however, they seem to have disappeared again, and thus the time of the first Germanic state formation may be viewed as the beginning of a new and this time lasting Jewification of Central and Northern Europe. A development set in which has always been the same or similar wherever the Jews encountered Aryan peoples.
