Various Acts Of The Intellect

“The possible intellect is a single faculty, but it is given different names according to its different acts.  Every power is specified by its formal object… The intellect receives different names according to its different acts; it is called memory, reason, inferior reason, superior reason, speculative intellect, practical intellect.  The memory is the intellect as it conserves intelligible species… The reason is the intellect as it proceeds from one known truth to another, in order to acquire new knowledge.” (Henri Grenier, Thomistic Philosophy, Vol. 1, pp. 467-468)
