That the world is not the embodiment of an eternal rationality can be conclusively proved by the fact that the piece of the worldthat we know--I mean our human reason--is not so very rational. And if it is not eternally and completely wise and rational, then the rest of the world will not be either; here the conclusion a minori ad majus, a parte ad totum applies, and does so with decisive force.
Friedrich NietzscheHowever modest one may be in one's demand for intellectual cleanliness, one cannot help feeling, when coming into contact with the New Testament, a kind of inexpressible discomfiture: for the unchecked impudence with which the least qualified want to raise their voice on the greatest problems, and even claim to be judges of such things, surpasses all measure. The shameless levity with which the most intractable problems (life, world, God, purpose of life) are spoken of, as if they were not problems at all but simply things that these little bigots knew!
Friedrich NietzscheI have not come to know atheism as a result of logical reasoning and still less as an event in my life: in me it is a matter of instinct.
