“As this is written, a sow bug crawls across a desk. If he is turned over on his back, one can observe the tremendous struggle he goes through to get on his feet again. During this interval he has a “purpose” in his life. When he succeeds, one can almost see the look of victory on his face. Off he goes, and one can imagine him telling his tale at the next meeting of sow bugs, looked up to by the younger generation as an insect who has made it. And yet mixed with his smugness is a little disappointment. Now that he has come out on top, life seems aimless. Maybe he will return in the hope of repeating his triumph. It might be worth marking his back with ink, so as to recognize him if he risks it. A courageous animal, the sow bug. No wonder he has survived for millions of years.”
