 Synderesis, although the morphology of its name makes it sound more like a disposition than a potentiality, is nevertheless the name of a dispositional potentiality: I do not say of an acquired disposition, but of an innate one. And thus, qua disposition it can be applied to what is related to it as a disposition, qua potentiality to what is related to it as a potentiality. From this it follows that it has a certain opposition to free choice, a certain opposition to the impulse [to sin] and sensuality, and a certain opposition to proheresis, which is part of free choice: qua potentiality, it is disparate from free choice and from sensuality, qua disposition it is disparate from proheresis and the impulse [to sin]…So, if anyone asks whether it is a potentiality or a disposition, the right answer lies in taking something in between: a dispositional potentiality.
