Whether the woman was fittingly made from the rib of man?

Objections

Objection 1 : It would seem that the woman should not have been formed from the rib of man. For the rib was much smaller than the woman's body. Now from a smaller thing a larger thing can be made only---either by addition (and then the woman ought to have been described as made out of that which was added, rather than out of the rib itself)---or by rarefaction, because, as Augustine says (Gen. ad lit. x): "A body cannot increase in bulk except by rarefaction." But the woman's body is not more rarefied than man's---at least, not in the proportion of a rib to Eve's body. Therefore Eve was not formed from a rib of Adam.
Objection 2 : Further, in those things which were first created there was nothing superfluous. Therefore a rib of Adam belonged to the integrity of his body. So, if a rib was removed, his body remained imperfect; which is unreasonable to suppose.
Objection 3 : Further, a rib cannot be removed from man without pain. But there was no pain before sin. Therefore it was not right for a rib to be taken from the man, that Eve might be made from it.
