Cyclopedia of Biblical, Theological and Ecclesiastical Literature

(from Μισεῖν , To Hate, and Λόγος , reason) is a term employed to designate the hatred of reason the most unreasonable kind of hatred that can possibly be thought of. But as Reason is the point of demarcation between man and brute, the misologist generally claims to be opposed only to the false application of the reasoning powers. (See Reason).
