"When," says Plotinus, "we have gone astray in the multiplicity of our corporal passions, we are punished, first by the straying itself, and afterwards, when we resume a body, by finding ourselves in worse conditions. The soul, on leaving the body, becomes that power which it has most developed. Let us, then, fly from base things here below, and raise ourselves to the intelligent world, so that we may not fall into the purely sensational life, by following images which are merely of the senses, or into the vegetative life, by indulging in mere physical pleasure and gluttony; let us raise ourselves to the intelligent world, to intelligence, to God. "Those who have exercised human faculties are born again as men. Those who have used their senses only pass into the bodies of brutes, and especially into the bodies of wild beasts, if they have been accustomed to yield to violent impulses of anger; so that the different bodies which they animate are conformable to their various propensities. Those who have done nothing but indulge their appetites pass into the bodies of luxurious and gluttonous animals. Others, who, instead of indulging concupiscence or anger, have degraded their senses by sloth, are reduced to vegetate in the plants, because in their previous existences they have exercised nothing but vegetative power, and have only worked to become trees. Those who have loved the enjoyment of music over much, but have led lives otherwise pure, pass into the bodies of melodious birds. Those who have governed tyrannically, but have no other vice, become eagles. Those who have spoken lightly of celestial things are changed into birds which fly towards the higher regions of the air. He who has acquired civil virtues becomes a man again, but if he does not possess these virtues to a sufficient extent, he is transformed into a sociable creature, such as the bee, or some other being of that species."
