It's extraordinary how we go through life with eyes half shut, with dull ears, with dormant thoughts. Perhaps it's just as well; and it may be that it is this very dullness that makes life to the incalculable majority so supportable and so welcome. Nevertheless, there can be but few of us who had never known one of these rare moments of awakening when we see, hear, understand ever so much--everything--in a flash--before we fall back again into our agreeable somnolence.
