"hatred of reason or knowledge," 1819; see miso- + -logy. Related: Misologist; misologue; misologistic. Greek misologia meant "hatred of argument."
Who hates science, but does not love wisdom the lesson on that account, is named a misologist. Misology commonly arises from a want of scientific knowledge, and from a certain sort of vanity therewith conjoined. And sometimes those, who at first cultivated the sciences with great diligence and success, but in the end found no satisfaction in all their knowledge, fall into the fault of misology. [John Richardson, introduction to English translation of Kant's "Knowledge," 1819]
