Their personal policy has become their planetary policy—and that’s never a very smart thing. — Harry Harrison

You must realize that living organisms will do anything to survive. Castaways at sea will drink their own urine in their need for water. Disgust at this is only the attitude of the overprotected who have never experienced extreme thirst or hunger.

The final product is a man-plant-animal symbiote that is admirably adapted for survival on this disaster world. No emotions to cause complications or desires that might interfere with pure survival. Complete ruthlessness—mankind has always been strong on this anyway, so it didn’t take much of a push.”

How large was mankind’s sense of obligation? The caveman first had this feeling for his mate, then for his family. It grew until men fought and died for the abstract ideas of cities and nations, then for whole planets. Would the time ever come when men might realize that the obligation should be to the largest and most encompassing reality of all—mankind? And beyond that to life of all kinds.
