But fear is nothing but a kind of avoidance of evil. Therefore it is not a special passion. Further, if fear were a special passion, it would be chiefly in the irascible part. Therefore fear is not a special passion, since it belongs to different powers. Now fear has a special object, as hope has.
Consequently fear is a special passion of the soul.
Wherefore, though avoidance be something common, yet fear is a special passion. Therefore there is also a natural fear. But there is a hope of nature, as is evident from Rm. Therefore there is also a fear of nature. On the contrary, That which is natural is common to things animate and inanimate.
