The authors identify sixteen habits. Each is clearly defined and described. They see these as critical components of a fully developed intellect. In a brief but thoughtful review of related literature and research, a strong case is made that these are the skills that can set cognitive efforts sailing into highly productive waters. The thesis the series is built around is summarized in this brief paragraph.
Abilities alone are dry and dormant.
Passions, motivation, sensitivities, and values all play a role in bringing intelligent behavior to life. Defining intelligence as a matter of ability, without honoring all the other elements that enliven it fails to capture its human spark. The habits of mind express a character-centered view of intelligence that honors the role of temperament and individual difference. The four books together provide a complete teaching guide. They span learning activities, assessments, and strategies for integrating habits into the total curriculum of the school.
