nam vel uti pueri trepidant atque omnia caecis

in tenebris metuunt, sic nos in luce timemus

inter dum, nihilo quae sunt metuenda magis quam

quae pueri in tenebris pavitant finguntque futura.

hunc igitur terrorem animi tenebrasque necessest

non radii solis neque lucida tela diei

discutiant, sed naturae species ratioque. 

(Lucretius, De Rerum Natura 2.55-61)

For just as children tremble and fear everything in blinding darkness, so we even in daylight sometimes dread things that are no more terrible than the future terrors imagined by children shuddering in the dark. This terrifying darkness that enshrouds the mind must be dispelled not by the sun's rays and the dazzling darts of day, but by study of the superficial aspect and underlying principle of nature.
