Had the world taken a somewhat different course, and had some billions of people made other decisions, or similar decisions at some points earlier or later than they actually made them, billions of additional human beings might have come to exist, or billions of human beings different in key respects from those who actually entered into existence. These are “the absent ones”, “whose” non-existence, strangely, is regretted by no one. “Strangely”, because it is clear that most people would be inclined to reject any hypothetical alternative world-course in which they themselves would never have begun to exist.
