“
At present, however, science, spurred on by its powerful delusion, is hurrying unstoppably to its limits, where the optimism hidden in the essence of logic will founder and break up. For there is an infinite number of points on the periphery of the circle of science, and while we have no way of foreseeing how the circle could ever be completed, a noble and gifted man inevitably encounters, before the mid-point of his existence, boundary points on the periphery like this, where he stares into that which cannot be illuminated. When, to his horror, he sees how logic curls up around itself at these limits and finally bites its own tail, then a new form of knowledge breaks through, tragic knowledge, which, simply to be endured, needs art for protection and as medicine.”
Friedrich Nietzsche, “Foreword to Richard Wagner” in The Birth of Tragedy, ed. R. Geuss & R. Speirs, Cambridge, 2007, 163. (p.114)
