Intellectualism is the mental perspective that emphasizes the use, development, and exercise of the intellect, and is identified with the life of the mind of the intellectual.[1] In the field of philosophy, the term intellectualism indicates one of two ways of critically thinking about the character of the world: (i) rationalism, which is knowledge derived solely from reason; and (ii) empiricism, which is knowledge derived solely from sense experience. Each intellectual approach attempts to eliminate fallacies that ignore, mistake, or distort evidence about "what ought to be" instead of "what is" the character of the world.[2][3]
Moreover, hierarchical intellectualism is a theory of intelligence which postulates that the mental capabilities that constitute intelligence occur and are arranged in a hierarchy ranging from the general to the specific, e.g. the I.Q. test.[4]
