Abstract. This article analyzes the intellectual virtues in Thomas Aquinas’ philosophy.Thomistic epistemology can be considered a true virtue epistemology. Cognitive habits andintentional species make intelligence grow. The virtue of prudence is accompanied by an arrayof satellite-virtues that allow not only moral rectitude, but also the correct performance ofrational human activities in all areas, including speculative tasks. These virtues are moral andintellectual at the same time, involving a special connection between knowledge and affectivity.Two special intellectual virtues treated by Thomas Aquinas are described: intellectual humilityand studiousness (studiositas).Key-words.
