"“Some worlds have too much life,“ he says. “Life—crawling, pullulating, fecundating, smothering itself—worlds too clement, too full of the sciences which keep men alive—worlds which would drown themselves in their own semen, worlds which would pack all of their lands with crowds of big-bellied women—and so go down to death beneath the weight of their own fruitfulness. Then there are worlds which are bleak and barren and bitter, worlds which grind life like grain. Even with body modifications and with world-change machines, there are only a few hundred worlds which may be inhabited by the six intelligent races. Life is badly needed in the worst of these. It can be a deadly blessing on the best. When I say that life is needed or not needed in certain places, I am of course also saying that death is needed or not needed. I am not speaking of two different things, but of the same thing. Osiris and I are bookkeepers. We credit and we debit. We raise waves, or we cause waves to sink back again into the ocean. Can life be counted upon to limit itself? No. It is the mindless striving of two to become infinity. Can death be counted on to limit itself? Never. It is the equally mindless effort of zero to encompass infinity.”"
