A gentleman named John Henry Fabre conducted an experiment with Processionary Caterpillars.  They are so named because of their peculiar habit of blindly

following each other no matter how they are lined up or where they are going.  This man took a group of these tiny creatures and did something interesting with them.  He placed them in a circle.  For 24 hours the caterpillars dutifully

followed one another around and around. Then he did something else.  He placed the caterpillars on a round saucer full of pine needles (their favorite food).  For six days the mindless creatures moved around and around the saucer, literally dying of starvation and exhaustion even though an abundance of choice food was located less than two inches away.  You see, they had confused activity with accomplishment.
