PART V. BUT I perceive, O Asclepios, that thou art anxious to know in what manner Heaven and those who inhabit it can be the object of the aspiration and adoration of man; learn, then, O Asclepios, that to aspire after the God of heaven and all those who are therein is to render them frequent homage; for alone of all animated beings, divine and human, man is able to render it. The admiration, adoration, praise, and homage of man rejoice heaven and the celestial inhabitants; and the choir of the Muses has been sent among men by the supreme Divinity in order that the terrestrial world might not be without the sweet science of hymns; or rather that the human voice might celebrate Him who only is All, since He is the Father of all things, and that the tender harmonies of earth might ever unite themselves with the celestial choirs. Only a few men, rarely endowed with a pure intelligence, are entrusted with this holy function of beholding heaven clearly. Those in whom the confusion of their two natures holds the intelligence captive under the weight of the body, are appointed to have communion with the inferior elements. Man is not, then, debased because he has a mortal part; on the contrary, this mortality augments his aptitudes and his power; his double functions are possible to him only by his double nature; he is constituted in such a manner that he can embrace alike the terrestrial and the divine. I desire, O Asclepios, that thou mayest bring to this exposition all the attention and all the ardour of thy mind; for many are wanting in faith concerning these things. And now I am about to unfold true principles for the instruction of the holiest intelligences.
