XXIX.  Who spread the sky around us, and set the stars in order?  Or rather, first, can you tell me, of your own knowledge of the things in heaven, what are the sky and the stars; you who know not what lies at your very feet, and cannot even take the measure of yourself, and yet must busy yourself about what is above your nature, and gape at the illimitable?  For, granted that you understand orbits and periods, and waxings and wanings, and settings and risings, and some degrees and minutes, and all the other things which make you so proud of your wonderful knowledge; you have not arrived at comprehension of the realities themselves, but only at an observation of some movement, which, when confirmed by longer practice, and drawing the observations of many individuals into one generalization, and thence deducing a law, has acquired the name of Science (just as the lunar phenomena have become generally known to our sight), being the basis of this knowledge.  But if you are very scientific on this subject, and have a just claim to admiration, tell me what is the cause of this order and this movement.  How came the sun to be a beacon-fire to the whole world, and to all eyes like the leader of some chorus, concealing all the rest of the stars by his brightness, more completely than some of them conceal others.  The proof of this is that they shine against him, but he outshines them and does not even allow it to be perceived that they rose simultaneously with him, fair as a bridegroom, swift and great as a giant Ps. xix. 5. for I will not let his praises be sung from any other source than my own Scriptures—so mighty in strength that from one end to the other of the world he embraces all things in his heat, and there is nothing hid from the feeling thereof, but it fills both every eye with light, and every embodied creature with heat; warming, yet not burning, by the gentleness of its temper, and the order of its movement, present to all, and equally embracing all.
