Philosophic Sagacity is not philosophy is the main argument of D. A. Masolo. Based on Socratic method, his analysis shows how frequently tradition and opinion are based on insufficient reasoning. For him, true philosophy relies on analysis, definition, and explanation. Pre-Socratic knowledge has no place in strict philosophy. Philosophic sagacity, he believes, falls into the category of pre-Socratic philosophy. Both fail in a consistent attitude towards, and practice of, rational explanation, despite the presence of the "sage" and the discourse with him/her. A mere discussion of a topic does not have the high degree of abstraction, conceptual analysis, and relation which, according to him, are the essence of strict philosophy.
