Abstract
This paper investigates Aquinas’s thought on the vis cogitativa, in order to determine whether Aquinas’s use of the inner sense of the vis cogitative is an embarrassment , or whether it is rather an important element in Aquinas’s philosophy of mind that calls for serious study . An examination of Aquinas’s theory of inner sense reveals that, for Aquinas, the vis cogitativa has two cognitive functions: to be aware of an individual as an individual, and to recognize an individual as a member of a kind. If Aquinas’ philosophy of mind did not include some account of the vis cogitativa, then it would not be able to accommodate what for Aquinas is a principal ontological category
