It would seem that when a heavenly body ceases to shine by its own light, it becomes capable of breeding eyes with which to profit by the light other bodies are shedding; whereas, so long as it was itself on fire, no part of it could see. Is life a gift which cooling stars receive from those still incandescent, when some ray falls upon a moist spot, making it a focus of warmth and luminous energy, and reversing at that point the general refrigeration? It is certain, at any rate, that if light did not pour down from the sun no earthly animal would have developed an eye. Yet there was another partner in this business of seeing, who would have flatly refused to undertake it, had the sole profit been the possibility of star-gazing. Star-gazing is an ulterior platonic homage which we pay to our celestial sources, as a sort of pious acknowledgment of their munificence in unconsciously begetting us. But this is an acknowledgment which they are far from demanding or noticing, not being vain or anxious to be admired, like popular gods; and if we omitted it, they would continue to perform their offices towards us with the same contemptuous regularity. Star-gazing is, therefore, a pure waste of time in the estimation of the other partner in vision, besides celestial light--I mean, that clod of moist earth which the light quickens, that plastic home-keeping parent of the mind, whom we might call old mother Psyche, and whose primary care is to keep the body in order and guide it prudently over the earth's surface. For such a purpose the direct rays of the sun are blinding, and those of the moon and stars fit only to breed lunatics. To mother Psyche it seems a blessing that the view of the infinite from the earth is so often intercepted; else it might have sunk into her heart (for she has watched through many a night in her long vegetative career), and might have stretched her comfortable industrious sanity into a sort of divine madness or reason, very disconcerting in her business. Indeed, she would never have consented to look or to see at all, except for this circumstance, that the rays coming from heavenly bodies are reflected by earthly bodies upon one another; so that by becoming sensitive to light the Psyche could receive a most useful warning of what to seek or to avoid. Instead of merely stretching or poking or sniffing through the world, she could now map it at a glance, and turn instinct into foresight.
