With a large number of people, it is quite evident that their power of sight completely dominates over their power of thought; they seem to be conscious of existence only when they are making a noise; unless indeed they happen to be smoking, for this serves a similar end. It is for the same reason that they never fail to be all eyes and ears for what is going on around them.
