 On one interpretation, the argument is this: the ending of life is not bad, since the only thing we could hold against it is the fact that it is followed by our nonexistence, yet the latter is not objectionable, as is shown by the fact that we do not object to our nonexistence before birth. So understood, the symmetry argument is weak. It would have some force for someone who thought initially that death puts us into a state or condition that is ghastly, perhaps painful, but that need not be our complaint. Instead, our complaint might be that death precludes our having more good life. Notice that the mirror image of death is birth (or, more precisely, becoming alive), and the two affect us in very different ways: birth makes life possible; if a life ends up being good for us, birth starts a good thing going. Death makes further life impossible; it brings a good thing to a close.
