XXXII. (100) "But of the tree of the knowledge of good and evil he shall not eat." Therefore this tree is not in the Paradise. For God encourages them to eat of every tree that is in the Paradise. But when he forbids them to eat of this tree, it is plain that it is not in the Paradise; and this is in accordance with natural philosophy. For it is there in its essence, as I have said before, and it is not there in its power. For as in wax there are potentially many seals, but in actual fact only one which has been carved on it, so also in the soul, which resembles wax, all impressions whatever are contained potentially; but in really one single characteristic which is stamped upon it has possession of it; until it is effaced by some other which makes a deeper and more conspicuous impression. (101) Again, this, also, may be made the subject of a question. When God recommends men to eat of every tree in the Paradise, he is addressing his exhortation to one individual: but when he forbids him to eat of the tree of the knowledge of good and evil he is speaking to him as to many. For in the one case he says, "Thou mayest freely eat of all;" but in the second instance, "Ye shall not eat;" and "In the day in which ye shall eat," not "thou shalt eat;" and "Ye shall die," not "Thou shalt die." (102) We must, therefore, say this, --that the first good is rare, imparted to but few; but the evil is comprehensive. On this account it is a hard matter to find one single man wise and faithful, but the number of bad men is beyond all computation. Very appropriately, therefore, God does not address his exhortation to nourish one's self amid the virtues, to one individual, but he encourages many to abstain from extravagant wickedness; for innumerable men are addicted to it. (103) In the second place, for the due comprehension and adoption of virtue man requires one thing alone, namely reason. But the body not only does not co-operate in it at all, but rather impedes the progress of the reason towards it. For it may be almost called the peculiar task of wisdom to alienate itself from the body and form the corporeal appetites. But for the enjoyment of evil it is not only necessary for a man to have mind in some degree, but also senses, and reason, and a body. (104) For the bad man has need of all these things for the completion of his own wickedness. Since how will he be able to divulge the sacred mysteries unless he has the organ of voice? And how will he be able to indulge in pleasures if he be deprived of the belly and the organs of sensation? Very properly, therefore, does Moses address reason alone on the subject of the acquisition of virtue, for reason is, as I have said before, the only thing of which there is need for the establishment of virtue. But for indulgence in vice a man requires many things--soul, and reason, and the external senses of the body; for it is through all these organs that vice is exhibited.
