Even the antique Humanist and Statesman Cicero could see in his dreams that the heavenly bodies sing with cosmic music. Humans are evolved Big Brains, everyone a potential Humanist-Scientist, born to intuit deep truths of the universe even in our dreams if need be. Homo sapiens scientia.
A generous quotation follows. I encourage you to relish each word.
10. And, as I gazed on these things with amazement, when I recovered myself: “What,” I asked, “what is this sound that fills my ears, so loud and sweet?” “This,” he replied, “is that sound, which divided in intervals, unequal, indeed, yet still exactly measured in their fixed proportion, is produced by the impetus and movement of the spheres themselves, and blending sharp tones with grave, therewith makes changing symphonies in unvarying harmony. For not only is it impossible that such vast movements should sweep on in silence; but, by a natural law, the outermost parts on the one side give a grave, and on the other a sharp sound. Wherefore the highest of all, the celestial zone equipped with stars, whose revolution is more swift, moves with a sharp, high note; while this one of the moon, as it is the lowest, with the deepest tone of all. For the earth, which is the ninth, remaining motionless is ever firmly planted in one spot, clinging closely to the centre of the universe. Now the revolutions of those eight spheres, of which two have the same power, produce seven sounds with well-marked intervals; and this number, generally speaking, is the mystic bond of all things in the universe, And learned men by imitating this with stringed instruments and melodies have opened for themselves the way back to this place, even as other men of noble nature, who have followed godlike aims in their life as men.
11. But the ears of men overpowered by the volume of the sound have grown deaf; and you have in you no duller sense than that of hearing; for instance, at the Catadupa as it is called, where the Nile rushes headlong from very high mountains, the tribe which dwells near that spot, owing to the loudness of the noise has lost the sense of hearing. But this sound of the whole universe revolving at the utmost speed is so awful that the ears of men cannot contain it; just as you are unable to look straight: at the sun, and your eyesight and its perceptions are overpowered by his rays.”
