Whether, in the absence of inward consent, a marriage is made by consent given in words of the present?

Objections

Objection 1 : It would seem that even in the absence of inward consent a marriage is made by consent expressed in words of the present. For "fraud and deceit should benefit no man," according to the law (cap. Ex Tenore, De Rescrip., cap. Si Vir, De cognat. spir.). Now he who gives consent in words without consenting in heart commits a fraud. Therefore he should not benefit by it, through being released of the bond of marriage.
Objection 2 : Further, the mental consent of one person cannot be known to another, except in so far as it is expressed in words. If then the expression of the words is not enough, and inward consent is required in both parties, neither of them will be able to know that he is truly married to the other; and consequently whenever he uses marriage he will commit fornication.
Objection 3 : Further, if a man is proved to have consented to take a certain woman to wife in words of the present tense, he is compelled under pain of excommunication to take her as his wife, even though he should say that he was wanting in mental consent, notwithstanding that afterwards he may have contracted marriage with another woman by words expressive of consent in the present. But this would not be the case if mental consent were requisite for marriage. Therefore it is not required.
