But without proper opportunities virtues indeed exist,
 
but they are immoveable and like silver and gold, which is of no use in the world, because it is treasured up in the secret recesses of the earth. On the other hand again, one can see innumerable persons, unmanly, intemperate, foolish, unjust, impious in their minds, but unable fully to display the disgraceful character of all their vices by reason of the want of opportunity to sin; but if any important or frequent opportunities present themselves, then filling earth and sea to its extremest boundaries with unspeakable wickedness, and leaving nothing whether great or small uninjured, they overturn and destroy everything at one blow. For as the power of fire is quiet when it has no fuel, but when there are proper materials it blazes up; so also all the powers which have reference to the virtue or vice of the soul are extinguished by want of opportunity, as I have said before, but are kindled by a favourable occasion and a happy concurrence of circumstances.
 Why then have I said these things, except with the object of teaching that Ham, the son of Noah, is the name of wickedness in a state of inactivity, but his grandson, Canaan, is the name of wickedness in a state of motion? For Ham being interpreted, means "warm," but Canaan means "commotion;" and warm in a body implies fever, but in the soul it implies wickedness. For as I suppose disease is the foundation of fever, not only of a part but of the whole body; so also wickedness is a disease of the whole soul. But at one time it is in a state of tranquillity, and at another in motion; now he calls its motion commotion ( σάλος ), which in the Hebrew language is called Canaan.
