Can any one, when he has considered the nature of other animals, which the providence of the Supreme God has made abject, with bodies bending down and prostrated to the earth, so that it may be understood from this that they have no intercourse with heaven, fail to understand that man alone of all animals is heavenly and divine, whose body raised from the ground, elevated countenance, and upright position, goes in quest of its origin, and despising, as it were, the lowliness of the earth, reaches forth to that which is on high, because he perceives that the highest good is to be sought by him in the highest place, and mindful of his condition in which God made him illustrious, looks towards his Maker? And Trismegistus most rightly called this looking a contemplation of God, which has no existence in the dumb animals. Since therefore wisdom, which is given to man alone, is nothing else but the knowledge of God, it is evident that the soul does not perish, nor undergo dissolution, but that it remains for ever, because it seeks after and loves God, who is everlasting, by the impulse of its very nature perceiving either from what source it has sprung, or to what it is about to return. Moreover, it is no slight proof of immortality that man alone makes use of the heavenly element. For, since the nature of the world consists of two elements which are opposed to one another—fire and water—of which the one is assigned to the heaven, the other to the earth, the other living creatures, because they are of the earth and mortal, make use of the element which is earthly and heavy: man alone makes use of fire, which is an element light, rising upward, and heavenly. But those things which are weighty depress to death, and those which are light elevate to life; because life is on high, and death below. And as there cannot be light without fire, so there cannot be life without light. Therefore fire is the element of light and life; from which it is evident that man who uses it is a partaker of an immortal condition, because that which causes life is familiar to him.
