Saint Anselm

“ For two beings who stand firm in truth are not equally deserving of praise, if one has never seen the punishment of sin, and the other forever witnesses its eternal reward. For it must not for a moment be supposed that good angels are upheld by the fall of evil angels, but by their own virtue. ”

“ You have proved that the evil angels must be restored from the human race; and from this reasoning it appears that the number of men chosen will not be less than that of fallen angels. But show, if you can, whether it will be greater. ”

“ For, if, without the fall of a part, the rest could not be upheld, it would follow, either that none could ever be upheld, or else that it was necessary for some one to fall, in order by his punishment to uphold the rest ”
