Logic, too, also rests on assumptions that do not correspond to anything in the real world, e.g., on the assumption that there areequal things, that the same thing is identical at different points in time: but this science arose as a result of the opposite belief (that such things actually exist in the real world). And it is the same with mathematics, which would certainly never have arisen if it had been understood from the beginning that there is no such thing in nature as a perfectly straight line, a true circle, and absolute measure.
Friedrich NietzscheA certain sense of cruelty towards oneself and others is Christian; hatred of those who think differently; the will to persecute. Mortal hostility against the masters of the earth, against the 'noble', that is also Christian; hatred of mind, of pride, courage, freedom, libertinage of mind, is Christian; hatred of the senses, of joy in general, is Christian.
Friedrich NietzscheIt is certain that the Jew, if he desired-or if they were driven to it, as the antisemites seem to wish-could now have the ascendancy, nay, literally the supremacy, over Europe; that they are not working or planning for that end is equally sure... The resourcefulness of the modern Jews, both in mind and soul, is extraordinary.
