beings, even after human beings have departed from the scene, and even if such principles are
never exemplified.
Here's an example designed to cement those points. It isn't pretty. I propose that the
following moral principle is eternally true: it is wrong to hammer nails into a living baby, chop it
into a billion pieces, boil the remains and force its mother to drink the concoction. Thank God
such a thing has never happened. Hopefully it never will. Neither of these points alters the truth of
the principle. Lest you think that such a principle comes into existence only when human babies
do, imagine the scenario only slightly changed. Suppose, a thousand years from now, that we
encounter beings just like us in every way, except that their sustaining systems are silicon-based,
rather than DNA-based. Still, it would be wrong to mutilate and murder such a baby. The fact that
such beings don't exist, and probably never will, doesn't alter the truth of the amended principle.
If you agree with that, then you have come around to the idea that moral principles might
be eternal. For such principles can be true even if they are never exemplified (much like the
principle about the trillion-sided figure). They can be true prior to the existence of the things they
mention (the alien infanticide example). They can be true even prior to the existence of a
language, or a language-user, capable of formulating them (two atoms and two atoms...). Since
that is so, what is to prevent us from saying that they were
always
true? For consider: if such
principles are allowed to be true even prior to the existence of the things they mention, then at
what earlier point did they become true? I don't see any non-arbitrary moment one could rely on.
Short of that, it seems that they were always true.
Brief recap. The main criticism we are entertaining in this chapter is the one that charges
ethical objectivists with an obscure account of the origins of moral truths. If moral skepticism is
false, then moral principles are not human inventions. If the Divine Command Theory is false, then
God doesn't make them up, either. No one else is left. So it must be that no one makes up the
moral rules. But if that is so, then it seems that objectivists are committed to the existence of
eternal moral truths, and that seemed very implausible.
My reply: first, an objective morality need not be an eternal one. Moral principles could be
