39 But perhaps, some one will urge, the Ruler of the world sent hither souls sprung from Himself for this purpose— a very rash thing for a man to say — that they which had been divine with Him, not coming into contact with the body and earthly limits, should be buried in the germs of men, spring from the womb, burst into and keep up the silliest wailings, draw the breasts in sucking, besmear and bedaub themselves with their own filth, then be hushed by the swaying of the frightened nurse and by the sound of rattles. Did He send souls hither for this reason, that they which had been but now sincere and of blameless virtue should learn as men to feign, to dissemble, to lie, to cheat, to deceive, to entrap with a flatterer's abjectness; to conceal one thing in the heart, express another in the countenance; to ensnare, to beguile the ignorant with crafty devices, to seek out poisons by means of numberless arts suggested by bad feelings, and to be fashioned with deceitful changeableness to suit circumstances?
Was it for this He sent souls, that, living till then in calm and undisturbed tranquillity, they might find in their bodies causes by which to become fierce and savage, cherish hatred and enmity, make war upon each other, subdue and overthrow states; load themselves with, and give themselves up to the yoke of slavery; and finally, be put the one in the other's power, having changed the condition in which they were born? Was it for this He sent souls, that, being made unmindful of the truth, and forgetful of what God was, they should make supplication to images which cannot move; address as superhuman deities pieces of wood, brass, and stones; ask aid of them with the blood of slain animals; make no mention of Himself: nay more, that some of them should doubt their own existence, or deny altogether that anything exists?
Was it for this He sent souls, that they which in their own abodes had been of one mind, equals in intellect and knowledge, after that they put on mortal forms, should be divided by differences of opinion; should have different views as to what is just, useful, and right; should contend about the objects of desire and aversion; should define the highest good and greatest evil differently; that, in seeking to know the truth of things, they should be hindered by their obscurity; and, as if bereft of eyesight, should see nothing clearly, and, wandering from the truth, should be led through uncertain bypaths of fancy?
