【Reason】 , 【understanding】 , 【intuition】 can all denote that power of the intellect by which man arrives at truth or knowledge.
【Reason】 centers attention on the faculty for order, sense, and rationality in thought, inference, and conclusion about perceptions.
【Understanding】 may sometimes widen the scope of 【reason】 to include both most thought processes leading to comprehension and also the resultant state of knowledge.
【Intuition】 (see intuitive at INSTINCTIVE ) stresses quick knowledge or comprehension without orderly 【reason】 , thought, or cogitation.
Used in connection with 19th century literary and philosophic notions, 【understanding】 often suggests the cold analytical order usually associated with 【reason】 and 【reason】 in turn suggests the spontaneity of 【intuition】 .
