Anselm. But this cannot be effected, except the price paid to God for the sin of man be something greater than all the universe besides God.
Boso. So it appears.
Anselm. Moreover, it is necessary that he who can give God anything of his own which is more valuable than all things in the possession of God, must be greater than all else but God himself.
Boso. I cannot deny it.
Anselm. Therefore none but God can make this satisfaction.
Boso. So it appears.
Anselm. But none but a man ought to do this, other wise man does not make the satisfaction.
Boso. Nothing seems more just.
Anselm. If it be necessary, therefore, as it appears, that the heavenly kingdom be made up of men, and this cannot be effected unless the aforesaid satisfaction be made, which none but God can make and none but man ought to make, it is necessary for the God-man to make it.
Boso. Now blessed be God! we have made a great discovery with regard to our question. Go on, therefore, as you have begun. For I hope that God will assist you.
Anselm. Now must we inquire how God can become man.
