Origins matter

How do they come among us, these bodies? We see around us smaller instances of ourselves, younger bodies, the less developed forms of children, infants, and babies, of those on four legs and those on two. But these smaller ones do not come from nowhere. They are not self-posited, nor simply deposited among us. How, then, do they arrive in our midst? Answer: we look back and we find them emerging out of the bodies of others, every single time.—Ethics at the Beginning of Life, page 14 (emphasis original)
