Origen on Lot's intercourse with his daughters, suggesting that the Stoic distinction between good, bad and indifferent can be applied

"The Greeks have examined the nature of actions, good, bad, and indifferent. Those who are succesful in this hold that it is only the motive which determines whether actions are good or bad; and they maintain that all actions proved to have been done without a motive are, strictly speaking, indifferent, and that the motive is laudable when the actions are rightly performed, but blameworthy when they are not. Concerning things indifferent they say, therefore, that strictly speaking it is a matter of moral indifference to have intercourse with one's daughters, although one ought not to do such a thing in civilized society." (Con. Cel. IV,45)
