Weakness of will and freedom of will in Thomas Aquinas

This paper aims to retrace the lines of Aquinas' theory of the plurality of philosophical uses of the semantics of the term incontinentia in the context of his sources. The Dominican theologian, even related to the mainstream of the Aristotelian akrasia, relies on different kind of sources, such as the Christian theological tradition (St. Paul and Augustine, in particular). In order to tries to understand the historical and philosophical reasons for variations of using a term, as well as their systematic significance, the paper shall underlines Aquino's commitments in His uses of incontinentia as conceptual translation of akrasia in the tradition of Aritstotle's Greek-Arabic commentaries. In the meantime, philosophical historical semantics, allows to retrace different frameworks, sources and traditions, both theological and moral, o/incontinentia when it occurs in theological texts such as Summa Theologiae.
