 A further problem with describing as Thomist a model of faith simply as firm belief that certain theological propositions are true is that Aquinas takes as central an act of ‘inner assent’ (Summa Theologiae, 2a2ae, 2, 1 (Aquinas [2006], 59–65)). This is problematic because, (i) in its dominant contemporary technical usage belief is taken to be a mental (intentional) state—a propositional attitude, namely, the attitude towards the relevant proposition that it is true; (ii) belief in this contemporary sense is widely agreed not to be under volitional control—not directly, anyway; yet (iii) Aquinas holds that the assent given in faith is under the control of the will. Aquinas need not, however, be construed as accepting ‘believing at will’, since assent may be construed as an act that has to be elicited yet terminates a process that is subject to the will—a process of inquiry, deliberation or pondering that involves mental actions, or, in the case of theist faith, a process of divine grace that can proceed only if it is not blocked by the will.
