Richard Carrier is a prolific writer on ancient history, atheism,
and naturalistic philosophy. I started reading him in the 1990s when he wrote articles for the early Secular Web. I especially enjoy his works on the ahistoricity
of Jesus. However, his case for the reduction of morality to a kind of
instrumentalism, for morality’s being “natural” and “scientific” because it’s a
matter merely of learning how to get what we most want, is frustrating because
it combines confusion with hubris. Still, various interesting issues crop up in
his discussion, so a critique is in order.
By way of providing some background, I should say that there
are three paramount theories in moral philosophy: deontology (we ought to do
our duty, because the form of action is most important), consequentialism (we
ought to act in the way that has the best results), and virtue ethics (we ought
to be the best kind of person). Carrier thinks that although philosophers have
been debating these theories for centuries, all three views are the same. They
reduce to each other and what emerges is instrumentalism, a reduction of moral
imperatives to “hypothetical” or conditional ones. So the meaning of “Thou
shalt not commit murder” is clarified when we translate it into a conditional
imperative that makes reference to the means needed to achieve a desire, such
as “If you want to stay out of jail or have self-respect or avoid being killed
in return (or insert some other desire here; generally it’s ‘If you want to be
happy…’), then you shouldn’t kill an innocent person.” For me, the question whether
the three leading moral theories are in conflict is a tempest in a teapot,
since I think naturalism has more radical implications for morality, which I’ll
come to in the last section below.
But let’s look closer at Carrier’s argument as it’s formulated
in his blog’s article on why moral imperatives are a posteriori and natural, meaning why they’re empirical like all
other purely factual statements. Carrier’s opponents are two kinds of moral
realists who both maintain that moral statements are true or false as opposed
to being, say, nonrational expressions of feelings. There’s the theist who trusts
that morality is supernatural in that it derives from God, and then there’s the
atheist who thinks morality is non-natural in the same way that qualia or
normativity in general are, in that their elucidation is beyond the purview of
scientific methods, but not beyond philosophical ones. Carrier is aghast
because his brand of atheism gives no quarter to theism, and his secular
humanism is progressive so he’s opposed to defeatism with respect to the
mission to solve all mysteries in the world. Contrary to Nietzsche, the sky
isn’t falling just because God, the traditional guarantor of morality, is fictitious;
liberal values are secured by reason, not faith. And instead of declaring that
some parts of the world are incomprehensible, we should be methodical in our
naturalism: we should assume that everything is naturally explainable until
proven otherwise. In particular, morality
is both real and natural, Carrier says, because it’s about the possibility that
some actions are better or worse at achieving our best desires. Those
desires are the ones we care about most and the ones we would have were we presented
with all the relevant information bearing on ourselves and the world, and were
we to think logically about what we most want out of life.
What’s Natural?
Carrier pontificates about how this or that is obviously
“natural” in that it’s a part of the scientifically-explainable universe. For
example, social properties are just as natural as quarks and sodium, he says,
since sociology reduces to physics via psychology, neurology, and chemistry.
The greater complexity of social systems is no matter, since sodium is likewise
‘more complex than “just quarks in motion,” which is why sodium is different
from uranium, for example, even though both are just “quarks in motion.”’
There are at least two problems with this. First, although
he grants that “brains interacting in social systems behave in ways that
reflect the structure and behavior of the social system,” he doesn’t grasp that
a scientific model has implicit meanings, or connotations, as well as explicit
ones (denotations). It doesn’t matter if
minds are nothing but brains, if the sets of symbols needed to explain the
two orders are incommensurable. A social system may be metaphysically
nothing but “atoms in motion,” but there is no sense of “motion” that explains
both what atoms and societies do, without palpable equivocation. The word
“motion” is defined differently in sociology and in physics. For example, a
particle’s velocity is not like a political party’s motion to pass a bill. And
reducibility applies to theories, not to the things to which the theories refer
irrespective of how they may be understood using different languages or
conceptual frameworks like sociology or physics. So denotatively or extensionally,
that is with respect to the immediate reference of words, the meanings of “society”
and “huge group of atoms” may be identical, but that doesn’t mean there’s a
single, coherent set of concepts for explaining what societies and atoms do as
seen from different orders of magnitude. Implicitly or intensionally, that is
with respect to the words’ indirect meanings in virtue of their relation to
background concepts, sociology isn’t reducible to physics, because the full
meanings of the terms used to explain what happens in a society as such don’t
translate into psychology or neurology or chemistry or physics. Only the
extensions or the referents are assumed to be ultimately the same, regardless
of our inability to explain without gaps how their identity manifests in the
different levels of behaviour. The behaviours perceived from different vantage
points, such as those of an appalled American voter witnessing her country’s cultural
descent into madness, and of a blurry-eyed scientist staring at a computer
screen at CERN, are not at all the same in that they’re not explainable by means
of any single coherent set of symbols. You need at least two theoretical discourses to be able to predict what will
happen at those levels of being.
