Man alone, he tells us, of all animal creation receives reward and punishment. The other animals have neither merit nor guilt. To be sure, their fortune in life depends upon the manner in which they respond to their environment, but this is not in the way of reward and punishment, but a natural consequence of their natural constitution. With man it is different, and this is because of the responsible position man occupies, having been given the privilege and the ability to control all animal creation.[158] The psychological basis of virtue in Abraham bar Hiyya is Platonic in origin, as it is in Pseudo-Bahya, though we do not find the four cardinal virtues and the derivation of justice from a harmonious combination of the other three as in the Republic of Plato, to which Pseudo-Bahya is ultimately indebted. Man has three powers, we are told, which some call three souls. One is the power by which he grows and multiplies like the plants of the field. The second is that by which he moves from place to place. These two powers he has in common with the animal. The third is that by which he distinguishes between good and evil, between truth and falsehood, between a thing and its opposite, and by which he acquires wisdom and knowledge. This is the soul which distinguishes him from the other animals. If this soul prevails over the lower two powers, the man is called meritorious and perfect. If on the other hand the latter prevail over the soul, the man is accounted like a beast, and is called wicked and an evil doer. God gives merit to the animal soul for the sake of the rational soul if the former is obedient to the latter; and on the other hand imputes guilt to the rational soul and punishes her for the guilt of the animal soul because she did not succeed in overcoming the latter.[159] The question of the relative superiority of the naturally good who feels no temptation to do wrong, and the temperamental person who has to sustain a constant struggle with his passions and desires in order to overcome them is decided by Abraham bar Hiyya in favor of the former on the ground that the latter is never free from evil thought, whereas the former is. And he quotes the Rabbis of the Talmud, according to whom the reward in the future world is not the same for the two types of men. He who must overcome temptation before he can subject his lower nature to his reason is rewarded in the next world in a manner bearing resemblance to the goods and pleasures of this world, and described as precious stones and tables of gold laden with good things to eat. On the other hand, the reward of the naturally perfect who is free from temptation is purely spiritual, and bears no earthly traces. These men are represented as "sitting under the Throne of Glory with their crowns on their heads and delighting in the splendor of the Shekinah."[160]
