"Kolakowski has long been a favorite of conservatives being one of the few prominent humanistic intellectuals on the "right" (in some suitably loose sense of "right"). His best-known work, the 3-volume Main Currents of Marxism, is a useful reference work, but that's all: it is comprehensive, detailed, and relentlessly superficial philosophically. His other works of philosophy--books on Hume, on Husserl, etc.--are largely irrelevant to philosophical scholarship, rarely discussed, barely known."
