As a formidably cohesive group whose loyalty to their ethnic kindred vastly outstrips their loyalty to the non-Jewish nations within which they dwell, Jews should absolutely never, Schopenhauer affirmed, be allowed to play any role whatsoever in the governance of these nations. If allowed to do so they would unquestionably exploit this power for their own ends — inevitably at the expense of the majority non-Jewish population:
It follows from this that it is absurd to want to concede to them a share in the government or administration of any country. Originally amalgamated and one with their state, their religion is by no means the main issue here, but rather merely the bond that holds them together, the point de ralliement [rallying-point], and the banner whereby they recognize one another. This is also seen in the fact that even the converted Jew who has been baptized does not by any means bring upon himself the hatred and loathing of all the rest [of the Jews], as do all other apostates. On the contrary, he continues as a rule to be their friend and companion and to regard them as his true countrymen, naturally with a few orthodox exceptions. … Accordingly, it is an extremely superficial and false view to regard the Jews merely as a religious sect. But if, in order to countenance this error, Judaism is described by an expression borrowed from the Christian Church as “Jewish Confession,” then this is a fundamentally false expression which is deliberately calculated to mislead and should not be allowed at all. On the contrary, “Jewish Nation” is the correct expression. The Jews have absolutely no confession; monotheism is part of their nationality and political constitution and is with them a matter of course.
