Whether the damned can make use of the knowledge they had in this world? [*Cf. FP, Question [89]]

Objections

Objection 1 : It would seem that the damned are unable to make use of the knowledge they had in this world. For there is very great pleasure in the consideration of knowledge. But we must not admit that they have any pleasure. Therefore they cannot make use of the knowledge they had heretofore, by applying their consideration thereto.
Objection 2 : Further, the damned suffer greater pains than any pains of this world. Now in this world, when one is in very great pain, it is impossible to consider any intelligible conclusions, through being distracted by the pains that one suffers. Much less therefore can one do so in hell.
Objection 3 : Further, the damned are subject to time. But "length of time is the cause of forgetfulness" (Phys. lib. iv, 13). Therefore the damned will forget what they knew here.
