In the study of the human mind, intellect is the ability of the human mind to reach correct conclusions about what is true and what is false in reality; and how to solve problems. Translated from the Ancient Greek philosophical concept nous, intellect derived from the Latin ("to understand"), from which the term intelligence in the French and English languages is also derived. The discussion of intellect can be divided into two areas that concern the relation between intelligence and intellect.
In classical philosophy and in medieval philosophy the intellect (nous) is the subject of the question: How do people know things? In Late Antiquity and in the Middle Ages, the intellect was the conceptual means of reconciling religious monotheism with philosophical or scientific study of Nature. This reconciliation made the intellect the conduit between the individual human soul, and the divine intellect of the cosmos. Aristotle first developed this with his distinction between the passive intellect and active intellect.
In psychology and in neuroscience, the controversial Theory of Multiple Intelligences applies the terms intelligence (emotion) and intellect (mind) to describe how people understand the world and reality.
Intellect and intelligence
As a branch of intelligence, intellect concerns the logical and the rational functions of the human mind, and usually is limited to facts and knowledge. Additional to the functions of linear logic and the patterns of formal logic the intellect also processes the non-linear functions of fuzzy logic and dialectical logic.
Intellect and intelligence are contrasted by etymology; derived from the Latin present active participle , the term intelligence denotes "to gather in between", whereas the term intellect, derived from the past participle of , denotes "what has been gathered". Therefore, intelligence relates to the creation of new categories of understanding, based upon similarities and differences, while intellect relates to understanding existing categories.
Development of intellect
A person's intellectual understanding of reality derives from a conceptual model of reality based upon the perception and the cognition of the material world of reality. The conceptual model of mind is composed of the mental and emotional processes by which a person seeks, finds, and applies logical solutions to the problems of life. The full potential of the intellect is achieved when a person acquires a factually accurate understanding of the real world, which is mirrored in the mind. The mature intellect is identified by the person's possessing the capability of emotional self-management, wherein they can encounter, face, and resolve problems of life without being overwhelmed by emotion.
Real-world experience is necessary to and for the development of a person's intellect, because, in resolving the problems of life, a person can intellectually comprehend a social circumstance (a time and a place) and so adjust their social behavior in order to act appropriately in the society of other people. Intellect develops when a person seeks an emotionally satisfactory solution to a problem; mental development occurs from the person's search for satisfactory solutions to the problems of life. Only experience of the real world can provide understanding of reality, which contributes to the person's intellectual development.
Structure of intellect
In 1955, the psychologist Joy Paul Guilford (1897–1987) proposed a Structural Intellect (SI) model in three dimensions: (i) Operations, (ii) Contents, and (iii) Products. Each parameter contains specific, discrete elements that are individually measured as autonomous units of the human mind. Intellectual operations are represented by cognition and memory, production (by divergent thinking and convergent thinking), and evaluation. Contents are figurative and symbolic, semantic and behavioral. Products are in units, classes, and relations, systems, transformations, and implications.
Intellect in psychotherapy
Intellectualization is a psychotherapeutic method based of intense intellectual focus in order to avoid dealing with a problem that occupies the attention of a person. In psychological praxis, intellectualization is a defense mechanism that blocks feelings in order to prevent anxiety and stress from acting upon and interfering with the psyche of the person, which otherwise would interfere with their normal functioning in real life. As psychotherapy, intellectualization is a rational, dispassionate, and scientific approach towards dealing with and resolving mental problems, which psychologically disturb the person.
