Nous

Nous (British: /ˈnaʊs/; US: /ˈnuːs/), sometimes equated to intellect or intelligence, is a philosophical term for the faculty of the human mind which is described in classical philosophy as necessary for understanding what is true or real. The three commonly used philosophical terms are from Greek, or νόος, and Latin and respectively. To describe the activity of this faculty, apart from verbs based on "understanding", the word "intellection" is sometimes used in philosophical contexts, and the Greek words noēsis and noein are sometimes also used. This activity is understood in a similar way, at least in some contexts, to the modern concept intuition.

In philosophy, common English translations include "understanding" and "mind"; or sometimes "thought" or "reason" (in the sense of that which reasons, not the activity of reasoning). It is also often described as something equivalent to perception except that it works within the mind ("the mind's eye"). It has been suggested that the basic meaning is something like "awareness". In colloquial British English, nous also denotes "good sense", which is close to one everyday meaning it had in Ancient Greece.
