Our dictionary tells us that the ant is a social insect. That means that ants live in a society and that in that society they depend on one another. The rules that govern them in their society have developed over the millions of years ants have been on the earth.

　But the scientists say that ants do by instinct most of the things that they do. It is true that man obeys instincts too, and in that way he is like the ant, but there is a difference between the instinct of the ant and that of the human being. The difference lies in the fact that man can decide between the action that his instinct urges and that which reason suggests.
