In all these cases the mind rather suffers than acts, and therefore it is not an affection _to be moved_, but _to give way_ to that motion, and to follow willingly what was started by chance—these are not affections, but impulses of the body. The bravest man in the world may look pale when he puts on his armor, his knees knock, and his heart work before the battle is joined: but these are only _motions_; whereas _anger_ is an _excursion_, and proposes revenge or punishment, which cannot be without the mind. As fear flies, so anger assaults; and it is not possible to resolve, either upon violence or caution, without the concurrence of the will.
