Context

“Therefore free-will must be either a power or a habit, or a power with a habit. That it is neither a habit nor a power together with a habit, can be clearly proved in two ways. First of all, because, if it is a habit, it must be a natural habit; for it is natural to man to have a free-will. But there is not natural habit in us with respect to those things which come under free-will: for we are naturally inclined to those things of which we have natural habits—for instance, to assent to first principles: while those things to which we are naturally inclined are not subject to free-will, as we have said of the desire of happiness” source
