Intellectualism is the mental perspective that emphasizes the use, the development, and the exercise of the intellect; and also identifies the life of the mind of the intellectual person. In the field of philosophy, the term intellectualism is synonymous with rationalism, knowledge derived from reason. In the field of sociology, the term intellectualism also has a socially negative connotation about intellectual people giving "too much attention to thinking" (single-mindedness of purpose) and thus show an "absence of affection and feeling" (emotional coldness). Hierarchical Intellectualism is any hierarchical theory of intelligence which postulates that the mental abilities that constitute intelligence occur and are arranged in a hierarchy (series of levels) that ranges from the general to the specific, e.g. the I.Q. test.
