Intellect is a term used in studies of the humanmind, and refers to the ability of the mind to come to correct conclusions about what is true or real, and about how to solve problems. Historically the term comes from the Greek philosophical term nous, which was translated into Latin as intellectus (derived from the verb intelligere) and into French (and then English) as intelligence.
Discussion of the intellect can be divided into two broad areas. In both of these areas, the terms "intellect" and "intelligence" have continued to be used as related words.
Intellect and Nous in philosophy. In philosophy, especially in classical and medieval philosophy the intellect or nous is an important subject connected to the question of how humans can know things. Especially during late antiquity and the middle ages, the intellect was often proposed as a concept which could reconcile philosophical and scientific understandings of nature with monotheistic religious understandings, by making the intellect a link between each human soul, and the divine intellect (or intellects) of the cosmos itself. (During the Latin Middle Ages a distinction developed whereby the term "intelligence" was typically used to refer to the incorporeal beings which governed the celestial spheres in many of these accounts.) Also see: passive intellect and active intellect.
Intellect and Intelligence in psychology. In modern psychology and neuroscience, intelligence and intellect are used as terms describing mental ability (or abilities) that allow people to understand. A distinction is sometimes made whereby intellect is considered to be related to "facts" in contrast to intelligence concerning "feelings". Intellect refers to the cognition and rational mental processes gained through external input rather than internal.
