Of the many points of contention
existing between atheists and theists, the topic of morality
frequently takes center stage. Theists often insist that without a
god to anchor objective moral obligations and duties, humans are free to behave anyway they please. Atheists counter that
they too espouse ethical positions, and that to ground morality in a
mythical god does nothing to address the problem of ethics in a
post-Christian world. The debate ultimately turns upon the
origins of morality and whether these origins provide sufficient
reason to compel morally responsible behavior.
No one denies that
atheists routinely behave ethically; in many cases their behavior is
identical to that of theists, and the Christian community ought to
acknowledge their sincere desire to live responsibly. What remains
uncertain is the legitimacy of their intellectual justification for
privileging any one moral system over another. While we may certainly
commend atheists for their eagerness to seek goodness over evil, we
must gently remind them that their worldview makes no allowance for
the existence of objective moral duties, and if they oppose theism
they must also relinquish any claim to a pervading moral reality.
Why Bother Arguing?
This tactic is difficult for even some
Christians to understand. Isn't it enough that atheists are trying to
do good? Shouldn't we encourage them to behave ethically and stop
quibbling over philosophical nuances? All valid points, but I think
it absolutely essential that we demonstrate the inability of the
prevailing secular models – namely materialism or secular humanism
– to provide a cogent account of one of the most fundamental
concerns confronting humankind: ethics. When the atheistic
paradigm is shown to fall short of satisfying our need to order our
interactions with one another, the intellectually honest atheist must
chose to either abandon ethics altogether, or to reconsider theism.
Driving the debate toward this dichotomy seems to me both
compassionate and intellectually responsible.
The Problem of Objective Moral
Duties
Are atheists really in such a
philosophical predicament? Let us quickly consider their limited
options. Given secular naturalism, materialism, physicalism or any
similar atheistic worldview which precludes the existence of anything
beyond corporeal matter, an atheist must derive his or her moral
system from the physical processes and chemical interactions which
constitute the material world. The primary mechanism responsible for
practically all of these phenomena, claims the materialist, is
natural selection. If the atheist wishes to provide a credible
argument for the existence of objective moral duties she must not
only show how natural selection produces ethical inclinations in
human beings, but also demonstrate why we ought to continue
abiding by those conditioned behaviors even after we have discovered
their contingent, biologically derived origin in a random process of
mutation. The problem is that we can easily imagine how the environmental constraints
which allegedly shaped the evolution of humankind could have been
different, which would have resulted in a different ethical impulse other than
the one we experience now. In other words, there is nothing at all
necessary about morality if its origins reside in natural
selection. Morality, as defined under this naturalistic model, might
change with the evolution of the species, and no compelling argument
for its universal application is available.
Alternatively, the atheist might argue
that the human being's capacity to reason has enabled her to make
decisions which benefit the species as a whole, and that each of us
is morally obligated to behave rationally in order to secure an orderly, just
civilization. Reason is certainly a powerful resource by which to
evaluate contending ethical claims, but only when working in the
service of an explicit goal. Only when atheists posit a goal, such as
securing social harmony, promoting equality or perpetuating the
species can they then apply reason to determine how to achieve it.
But an end goal, or teleology, is precisely what is missing in any
naturalistic account of the universe. Science and natural selection
offer no indication of there being any goal to its processes, only
random, directionless replication of DNA. Without a goal to focus our
ethical behavior, any atheistic preference for one moral system over
another reflects an arbitrary whim and cannot be defended
philosophically.
Nowhere Left to Turn
What else can the secular naturalist
offer in defense of objective moral duties? Unfortunately, nothing
else remains but a frighteningly indifferent universe which allows
for no distinction between any sorts of behavior, ethical or
otherwise. And while it's true that I have simplified the arguments
to permit a quick overview, we need only turn to one of atheism's
preeminent thinkers to arrive at the same conclusion. In his final
book before his death, Richard Rorty wrote, “There is however
nothing in existence to which our moral convictions should try to
correspond. [...] The answer to the question 'Are some human desires bad?'
is: No [...] There is no such thing as intrinsically evil desire.” This
refreshingly candid confession by a world-renown atheistic
philosopher promotes the only intellectually consistent position
atheism has on offer, moral relativism.
The sooner atheists confront the
unsettling consequences of their position the sooner they are likely
to turn to theism for answers. Christians have a responsibility to
exemplify compassion when debating atheists, but we can also leverage
the intellectual inconsistencies of their moral prejudices to draw
them into a deeper consideration of theism.
