Jewish question
In "Der Judenstaat" he writes: "The Jewish question persists wherever Jews live in appreciable numbers. Wherever it does not exist, it is brought in together with Jewish immigrants. We are naturally drawn into those places where we are not persecuted, and our appearance there gives rise to persecution. This is the case, and will inevitably be so, everywhere, even in highly civilised countries—see, for instance, France—so long as the Jewish question is not solved on the political level."
