Whether a man is bound to restore what he has not taken?

Objections

Objection 1 : It would seem that a man is bound to restore what he has not taken. For he that has inflicted a loss on a man is bound to remove that loss. Now it happens sometimes that the loss sustained is greater than the thing taken: for instance, if you dig up a man's seeds, you inflict on the sower a loss equal to the coming harvest, and thus you would seem to be bound to make restitution accordingly. Therefore a man is bound to restore what he has not taken.
Objection 2 : Further, he who retains his creditor's money beyond the stated time, would seem to occasion his loss of all his possible profits from that money, and yet he does not really take them. Therefore it seems that a man is bound to restore what he did not take.
Objection 3 : Further, human justice is derived from Divine justice. Now a man is bound to restore to God more than he has received from Him, according to Mt. 25:26, "Thou knewest that I reap where I sow not, and gather where I have not strewed." Therefore it is just that one should restore to a man also, something that one has not taken.
