At the deepest level of Western knowledge, Marxism introduced no real discontinuity; it found its place without difficulty, as a full, quiet, comfortable and, goodness knows, satisfying form for a time (its own), within an epistemological arrangement that welcomed it gladly (since it was this arrangement that was in fact making room for it) and that it, in return, had no intention of disturbing and, above all, no power to modify, even one jot, since it rested entirely upon it.
