All social orders command their members to imbibe in pipe dreams of posterity, the mirage of immortality, to keep them ahead of the extinction that would ensue in a few generations if the species did not replenish itself. This is the implicit, and most pestiferous, rationale for propagation: to become fully integrated into a society, one must offer it fresh blood. Naturally, the average set of parents does not conceive of their conception as a sacrificial act. These are civilized human beings we are talking about, and thus they are quite able to fill their heads with a panoply of less barbaric rationales for reproduction, among them being the consolidation of a spousal relationship; the expectation of new and enjoyable experiences in the parental role; the hope that one will pass the test as a mother or father; the pleasing of one’s own parents, not to forget their parents and possibly a great-grandparent still loitering about; the serenity of taking one’s place in the seemingly deathless lineage of a familial enterprise; the creation of individuals who will care for their paternal and maternal selves in their dotage; the quelling of a sense of guilt or selfishness for not having done their duty as human beings; and the squelching of that faint pathos that is associated with the childless. Such are some of the overpowering pressures upon those who would fertilize the future. These pressures build up in people throughout their lifetimes and must be released, just as everyone must evacuate their bowels or fall victim to a fecal impaction. And who, if they could help it, would suffer a building, painful fecal impaction? So we make bowel movements to relieve this pressure. Quite a few people make gardens because they cannot stand the pressure of not making a garden. Others commit murder because they cannot stand the pressure building up to kill someone, either a person known to them or a total stranger. Everything is like that. Our whole lives consist of metaphorical as well as actual bowel movements, one after the other. Releasing these pressures can have greater or lesser consequences in the scheme of our lives. But they are all pressures, all bowel movements of some kind. At a certain age, children are praised for making a bowel movement in the approved manner. Later on, the praise of others dies down for this achievement and our bowel movements become our own business, although we may continue to praise ourselves for them. But overpowering pressures go on governing our lives, and the release of these essentially bowel-movement pressures may once again come up for praise, congratulations, and huzzahs of all kinds.
Men may perish, but the world will neither celebrate nor mourn. It will go on.' His smile thinned. 'Would you like to know how?''No.''Animals will swell to fill the void left by men," he told her. 'And over-swell it, perhaps. There will be other extinctions and other recoveries. The sky will clear, but those who see it will not marvel at its many colors. Those ruins will collapse, burying treasures like this-' He waved at the walls. '-and this-' He picked up the spoon from her coffee tray and tossed it down again with a clatter. '-forever, but the world will go on. Years become centuries so easily when no one is there to count them. Centuries become millennia. The forests will reclaim the lands that Men have razed. Rivers will carve canyons across the scars left by this fallen cities. Mountains will rise up, trapping seas to dry under and uncaring sun and leaving the bones of whales to bleach in the newborn deserts for no one to find, no one to be inspired by thoughts of giants and dragons. And still the worlds will go on, and I will go on with it through ages that can only be measured by the coming and going of glaciers. The stars themselves will shift in the heavens and no one will be there to invent names for their new alignments or remember the stories of the old ones, no one but me. In time, the sun itself will begin to cool. Here on Earth, the world goes on and on as its remaining life passes through its last changes and dies away. It will be quiet. And lonely.' His mouth curved into a bitter line. 'But I'll live.''Stop it,' Lan whispered through numb lips.'I read once that the sun will someday swell and engulf this world before it burns itself out. Perhaps I will finally die with it. Or perhaps I' will continue to endure... my ashes pulled eternally apart through the frozen vacuum of space, and I with no more mouth to scream... still alive.
