Unpleasant creatures are so plentiful in the world that they cannot be overlooked. Were there only a few they might be ignored; but they throng, they thrust themselves forward, they shout to attract attention, they push the decent-looking out of the way. The ugliest women make the most noise; the ugliest men shove to the front in a crowd; the ugliest insects make their way into bed-chambers. Why Nature made so much ugliness, side by side with so much that is beautiful, only Nature knows. Some countries are made detestable to live in by the presence of hideous creatures. There is the fire-ant of the Amazon valley, which will put human beings to flight. There is the Mygale spider, covered with poisonous red hair, its body the size of a duck's egg, the spread of its legs covering eight inches, which scuttles into a room by moonlight and casts a horrible shadow upon the bed. There is the wolf-spider which, if a man passes near its lair, will leap out and pursue him, and bite him if it can. There are so many of these repulsive things that they cannot be disregarded. Some things can be kept out of the way: abattoirs, operating-theatres, vivisection-hells. People ignore and forget these, because they are not seen; but the man wolf-spider cannot be forgotten, because he leaps out and pursues those that come near his lurking-place. Nothing in the entire system of creation can be more inexplicable than the persistent cruelty of Nature. Death there must be, but Nature resents a painless death. Animals not only kill but torture those which are inferior to them. Mason-wasps deliberately vivisect spiders, which are insects extremely tenacious of life. It is the same all the way along the scale up to and including man. Nature does her work with bloody hands; birth, life, death, become a miserable dabble of blood and passion. Some people shut their eyes to it all; others cannot; others add to it; churches with their tolling bells and black masses revel in the mystic side of it.
