Looking at nature we see that

• if there is one speck of dust on the wall, more dust will collect there.
• It is sometimes hard to find one fly in the room, but if there is one fly we shall see that there are other flies near it.
• Where there is one ant or one sparrow, there will be other ants or sparrows near.
• In the jungle, where there is one parrot there will be a great many parrots in the same part of the forest.
• However much dogs may quarrel and fight, they enjoy being together best.
• The rabbit does not care to be among sparrows, nor does the donkey want to consort with serpents.
• Where there is one grain of wheat, more wheat grows; and where one finds one small rose-bush, there will be many roses.
