Some few intense enjoyments are given us in life; among them all, perhaps, there is none with so deep a charm as to sit by the side of those we love, and watch them sleeping. Sleep is so innocent, so peaceful in its mystery and its helplessness; and sitting there we can fancy ourselves the guardian angels holding off the thousand evils imagination paints for ever hanging over what is most precious, most dear to us. The long deep-drawn breathing; the smile we love to hope is called up over the features by our own presence in the heart; there are no moments in life we would exchange for the few we have spent by the side of these.

Arthur's commentary - The Nemesis of Faith (1849)
