Whether the damned are in material darkness?

Objections

Objection 1 : It would seem that the damned are not in material darkness. For commenting on Job 10:22, "But everlasting horror dwelleth," Gregory says (Moral. ix): "Although that fire will give no light for comfort, yet, that it may torment the more it does give light for a purpose, for by the light of its flame the wicked will see their followers whom they have drawn thither from the world." Therefore the darkness there is not material.
Objection 2 : Further, the damned see their own punishment, for this increases their punishment. But nothing is seen without light. Therefore there is no material darkness there.
Objection 3 : Further, there the damned will have the power of sight after being reunited to their bodies. But this power would be useless to them unless they see something. Therefore, since nothing is seen unless it be in the light, it would seem that they are not in absolute darkness.
