Martin Heidegger said this quote
“ Here, the asking of the question who we are is in fact more dangerous than any other opposition found at the same level of certainty about man (the final form of Marxism, which has essentially nothing to do with either Judaism or even with Russia; if somewhere a non-developed spiritualism is still slumbering, it is in the Russian people; Bolshevism is originally Western; it is a European possibility: the emergence of the masses, industry, technology, the extinction of Christianity; but inasmuch as the dominance of reason as an equalizing of everyone is but the consequence of Christianity and as the latter is fundamentally of Jewish origin (cf. Nietzsche's thought on the slave revolt with respect to morality), Bolshevism is in fact Jewish; but then Christianity is also fundamentally Bolshevist! And what are the decisions that become necessary on that basis?). But the danger of the question Who are we? is at the same time--if danger can necessitate what is highest--the sole path by which to succeed in coming to ourselves and thus in initiating the original salvation, that is, the justification of the Occident on the basis of its history. The danger of this question is in itself so essential for us that it loses the appearance of opposition to the new German will. ”
