Naturally, the superior race should win ... but superior by which standards ... and whose?

excerpt
 The females and children worked among the lichen growth, picking off the fattest, ripest leaves for their food and moisture, completing their arc of the circle of symbiosis.

The males worked at the surface of the canals, or in open excavations. Their wide, mutated hands chipped into the rock-hard clay, opening a channel which was to be filled with sand and then sealed off with clay on all sides and surface. That water might seep through the sand without evaporation, without loss, from the poles to the equator of Mars--seep unimpeded, so that moisture might reach the lichen plants of everyone, so that none might thirst or hunger.

The seepage must flow. Not even buried in the dim racial memory had there ever been one who took more than his share, for this would be like the fingers of one hand stealing blood from the fingers of the other.

Among the Mars race there were many words for contentment, kinship of each to all. There were words to express the ecstasy of watching the eternal stars, by night and by day, through the thin blackish atmosphere. There were words to express the joy of opening slitted nostrils to breathe deeply in those protected places where the blowing sands did not swirl, of opening folds of rubbery skin to catch the weak rays of the distant Sun.

But there were no words for "mine" as separate from "yours." And there was no urge to cry out, "Why am I here? What is the purpose of it all?"

Each had his purpose, serene, unquestioning. Each repaired or extended the seepage canals so that others, unborn, might know the same joys and ecstasies as they. The work was in itself a part of the total joy, and they resisted it no more than healthy lungs resist clear, cool air.

So far back that even the concept of beginnings had been forgotten, the interwoven fabric of their symbiotic interdependence seeped through their lives as naturally as the precious water seeped through the canal sands. As far back as that, they had achieved civilization.

Their kind of civilization.
