- Passive intellect
Passive intellect is a term used in both psychology and philosophy.
Psychology
Passive intellect (more properly, passive knowledge) is the psychological concept of knowledge that is not being actively used (as opposed to active knowledge). For example, if you simply know French, but do not happen to be speaking it at the moment, it would be considered passive knowledge. If you are speaking French, your knowledge of it is currently active knowledge for you. Passive intellect is sometimes represented by three straight lines of equal length stacked together [http://www.symbols.com/encyclopedia/10/1011.html] .
Philosophy
In Aristotle's psychology, the passive intellect ("nous pathetikos")corresponds to sensing/feeling part of the mind, in contrast with the
active intellect ("nous poietikos") or thinking part.Later philosophers, including
Averroes and St. Thomas Aquinas,elaborated on Aristotle's distinction between the active intellect and passive intellect. Other terms used are "material intellect" and "potential intellect", the point being that the active intellect works on the passive intellect to produce knowledge (acquired intellect), in the same way that actuality works on potentiality or form on matter.Averroes held that the passive intellect, being analogous to unformed matter, is a single substance common to all minds, and that the differences between individual minds are the product of the differences in their physical organisms and history of sense perceptions. Aquinas wrote a book in five chapters to refute this position.
