“The more these artificial renaissances strive to keep intact the letter of the original doctrines, the more they distort the original meaning, for truth is forged in an evolution of changing and conflicting ideas. Thought is faithful to itself largely through being ready to contradict itself, while preserving, as inherent elements of truth, the memory of the processes by which it was reached. The task of critical reflection is not merely to understand the various facts in their historical development but also to see through the notion of fact itself, in its development and therefore in its relativity.”
