Whether the aforesaid powers are more infected than the others?

Objections

Objection 1 : It would seem that the aforesaid powers are not more infected than the others. For the infection of original sin seems to pertain more to that part of the soul which can be first the subject of sin. Now this is the rational part, and chiefly the will. Therefore that power is most infected by original sin.
Objection 2 : Further, no power of the soul is infected by guilt, except in so far as it can obey reason. Now the generative power cannot obey reason, as stated in Ethic. i, 13. Therefore the generative power is not the most infected by original sin.
Objection 3 : Further, of all the senses the sight is the most spiritual and the nearest to reason, in so far "as it shows us how a number of things differ" (Metaph. i). But the infection of guilt is first of all in the reason. Therefore the sight is more infected than touch.
