Beneath the pseudo-scientific terminology one can in each case recognize a phantasy of which almost every element is to be found in phantasies which were already current in medieval Europe. The final, decisive battle of the Elect (be they the ‘Aryan race’ or the ‘proletariat’) against the hosts of evil (be they the Jews or the ‘bourgeoisie’); a dispensation on which the Elect are to be most amply compensated for all their sufferings by the joys of total domination or of total community or of both together; a world purified of all evil and in which history is to find its consummation - these ancient imaginings are with us still.
