 Why are Melia and Xeon considered noble by the end of the story?
It was a day soft and clear; a day accepted by the young, cherished by we old. In whose names Man finally left this earth, to seek his cousins among the stars. Saddened, but resigned and content to live in peace with his knowledge and his power. But I knew that where Xeon is, Melia must soon appear. And indeed it was but a moment before Melia slipped through the high grass to stand at his side. Indeed, Melia was on this account made the butt of many jokes and, I fear, would have had a lonely life of it had it not been for the friendship of Xeon. Everything has evaporated in Maternite. A man my age does not hurry in the heat of the midday sun—maddugs nenglishmin go out in the midday sun, as the ancients say, although I often wonder why—but Xeon and Melia ran all the way down to the city. They are of an age to enter manhood, and have all the energy such young men do. They were aware that they stood in the midst of an unprecedented happening; indeed, an emergency. They were created so long ago, indeed, that the ignorant believe them to have been constructed by the gods themselves. Xeon and Melia stopped as I mounted the steps, but I smiled and motioned them in. They accompanied me past the marble pillars into the cool recesses of the Hall, then seated themselves on the floor as I took my place by the great table. At such a time, many men feel impelled to make speeches, and one must not be disrespectful. Prayers and supplications were offered to the gods, priests were sent to sacrifice, and finally, as the light of the sun was falling between the pillars, the High Priest of the Maternite Machine was heard. Yet perhaps it is for the best, for those left were the most earnest and intelligent. Know, then, that once granted a few cells of Prelife, it is an easy matter for the Maternite Machine to add more and more; thus assuring us, as has always been, a continuous source of Prelife to be born by the Generating Machine as children. The machines bear the exact number of children each year to balance the number of us whom the gods claim. They quieted, breathing heavily, and I asked, "Is there no way, then, to produce more Prelife in order that the machines may produce more children for us?
