“The metaphysical constructions of the cosmos that we are obliged to witness in our own time either bear a suspicious similarity to older, and mostly much more dynamic and illuminating, intellectual schemes, or are products of the most execrable dilettantism.”  (Heinrich Rickert, The Limits of Concept Formation in the Natural Sciences [1902])

“All fanaticism [Schwärmerei] is and necessarily becomes a philosophy of nature.”  (Fichte, Characteristics of the Present Age [1806])
