“There is not a moment but preys upon you,—and upon all around you, not a moment in which you do not yourself become a destroyer. The most innocent walk deprives of life thousands of poor insects: one step destroys the fabric of the industrious ant, and converts a little world into chaos. No: it is not the great and rare calamities of the world, the floods which sweep away whole villages, the earthquakes which swallow up our towns, that affect me. My heart is wasted by the thought of that destructive power which lies concealed in every part of universal nature. Nature has formed nothing that does not consume itself, and every object near it: so that, surrounded by earth and air, and all the active powers, I wander on my way with aching heart; and the universe is to me a fearful monster, for ever devouring its own offspring.”
