Reflective, creative, and critical thinking—Three modes of anumāna. Reflective thinking begins in wonder about something perceived. Out of wonder, questions arise. Creative thinking begins as a mental effort to answer the questions of reflection. Sometimes these questions are answered spontaneously, by intuition, insight or inspiraton, rather than by deliberate effort. At its highest stage of development, creative thinking is śāstramūlaka philosophical speculation. Critical thinking examines to what extent an idea or argument fits the evidence and meets the requirements of logic. See Logic.
