Cur Deus Homo/Book Second/Chapter 12

CHAPTER XII
How, though he shares in our weakness, he is not therefore miserable.

Boso. All these things plainly show that he ought to be mortal and to partake of our weaknesses. But all these things are our miseries. Will he then be miserable?

Anselm. No, indeed! For as no advantage which one has apart from his choice constitutes happiness, so there is no misery in choosing to bear a loss, when the choice is a wise one and made without compulsion.

Boso. Certainly, this must be allowed.
