Any epistemological theory worthy of the name must address the skeptical
challenge. The skeptic begins with a fund of presumptively justified beliefs and
proceeds to argue that one can’t legitimately make inferences that go beyond
that evidence. For example, a skeptic about the material world argues that on
the basis of our sensory beliefs, we can equally well support the brain-in-thevat
hypothesis, the ideational world hypothesis, the evil demon hypothesis, the
material world hypothesis, etc. All of these hypotheses are underdetermined by
the evidence. The skeptical challenge is that since the evidence does not
support any one of these hypotheses over any other, we cannot justifiably
believe any of them.
A central problem with naturalistic approaches to epistemology, including
the one defended in this book, is that they fail to address the skeptical
challenge. Naturalists begin their epistemological investigations by making
substantive assumptions that skeptics are unwilling to grant: that there is a
material world, that there are other minds, etc. You face a dilemma. Either
you ignore the skeptical challenge, in which case your theory does not deserve
to be called an epistemological theory, or you beg the question against the
skeptic.
Let’s begin with a ‘‘live and let live’’ response to the skeptical problem.
Our approach to epistemology does not provide a solution to skepticism.
But what do we really want from an epistemological theory? It would
certainly be nice to have a theory that solved the problem of skepticism.
But it would also be nice to have a theory that provided useful guidance to
reasoners. An epistemological theory that provided a framework for how
to reason in an excellent manner could have many practical benefits. It
could provide a framework for thinking about diagnosis that led to better
medical outcomes, a framework for thinking about parole board decisions
that led to a less violent society, a framework for thinking about public
policy that helped the electorate support policies that better serve its
values, and so on. Now, one might legitimately wonder whether a useful
reason-guiding theory is possible; but one might equally well wonder
whether a theory that solves the problem of skepticism is possible. Our
point is that if philosophers insist that a theory of reasoning excellence
that has this ameliorative aim is not epistemology, well then, so much the
worse for epistemology.
The ‘‘live and let live’’ response notes that many successful theories
don’t do everything we might like them to do. Newton’s theory of motion was highly successful even though it does not explain all physical phenomena
(e.g., electromagnetic phenomena). So a theory of reasoning excellence
might be highly successful at providing useful guidance to
reasoners even though it does not solve some other epistemological
problems. In particular, it might well not solve the skeptical problem. So
we admit that we don’t have a solution to the skeptical challenge, but
we’re proposing a theory that aims to meet a different goal. Unless one
rejects this as a legitimate goal of epistemology, then the skeptic’s criticism
fails to uncover a problem with any theory, naturalistic or not, that has
this goal. And of course that includes Strategic Reliabilism.
The ‘‘live and let live’’ response is problematic for any naturalistic theory, like
yours, that takes reasoning excellence to be partly determined by the reliability
of reasoning strategies. You argue that according to Strategic Reliabilism,
one ought to use Goldberg’s Rule in making tentative diagnoses of
psychiatric patients on the basis of the MMPI. That’s because Goldberg’s Rule
has low costs and is reliable on problems that are significant. But the skeptic
can reformulate her challenge so that it is about reasoning excellence. If a
skeptical hypothesis is true, if, for example, there are no other minds or other
people, then Goldberg’s Rule would not be reliable after all. Given this possibility,
how could we ever know how to reason in an excellent fashion? The
problem with the ‘‘live and let live’’ response is that it fails to recognize that
the skeptical problem is so pervasive that it cannot be sidestepped or avoided.
In the face of this challenge, our inclination is to restrict our theory to
normal worlds—that is, non-skeptical worlds that are presumed to be like
our own (Goldman 1986, 107–9). A reasoning strategy is reliable when it
has a high truth ratio on the assumption that the world is as we presume it
to be, i.e., nonskeptical.
But the move to ‘‘normal worlds’’ is cheating. You escape the skeptical
challenge simply by ruling by fiat that the skeptical hypotheses are false. Is
there some principled reason that warrants the move to ‘‘normal worlds’’? Or
is this move simply motivated by the understandable but unprincipled desire
to avoid a difficult problem?
Technically, we are not ruling that the skeptical hypotheses are false. Our
point is that judgments of reasoning excellence are insensitive to whether
or not a skeptical hypothesis is true. There are two principled reasons for
this move to normal, non-skeptical worlds. First, the goal of Strategic Reliabilism is not to solve the problem of skepticism. It aims to be a useful
reason-guiding theory. This is a legitimate goal of epistemology. Strategic
Reliabilism should be assessed in terms of whether it meets this goal. If it
does, then the fact that it does not meet a different goal (solving the skeptical
problem) does not by itself give us a reason to doubt it. Rather, it
suggests that the epistemological theory that guides reasoning is not the
theory that will solve the problem of skepticism. Second, recall that Strategic
Reliabilism is supposed to articulate the normative principles that
guide the prescriptions of Ameliorative Psychology. A cursory examination
of Ameliorative Psychology makes evident that it ignores the skeptical
challenge; for example, it employs the processes and categories of contemporary
psychology. So given that our aim is to articulate the normative
presuppositions of Ameliorative Psychology, it is perfectly reasonable for
our theory to ignore the possibility of skepticism if the sciences does. And
the science does.
There are good, principled reasons for restricting Strategic Reliabilism
to normal worlds. Still, some might be disappointed. After all, Strategic
Reliabilism does not even hold out the hope of solving the problem of
skepticism. Is this a reason to have doubts about our theory? Perhaps.
Who wouldn’t prefer a lovely theory that both guided reason and solved
the problem of skepticism? For those who might be disappointed, however,
it’s important to recognize two points. First, there might be no
unified epistemological theory that meets all our goals. We suggest that
Strategic Reliabilism reflects the fact that you can’t always get what you
want, but if you try sometimes, you just might find you get what you need.
Second, even if the failure of Strategic Reliabilism to address the skeptical
challenge is a mark against it, that is not by itself a mark in favor of any
other approach. In particular, it is not a reason to believe that the standard
analytic approach to epistemology can yield a satisfying solution to the
skeptical problem.
Strategic Reliabilism recognizes that for most people dealing with everyday
issues, skepticism is not a significant problem. This is a point contextualists
make in defense of their account of justification (e.g., DeRose
1995). Our point is about what problems the excellent reasoner will tackle
and what problems she will ignore. At the risk of undermining our own
‘‘live and let live’’ response to the problem of skepticism, we should note
that as children of the 60s, we are nothing if not reflexive: our theory of
reasoning excellence applies to us as epistemologists as well. The philosopher
who takes skepticism seriously has made judgments, perhaps implicit, about what problems are important in epistemology. If naturalists
have not been sufficiently sensitive to the problems posed by the skeptical
challenge and other concerns of SAE, perhaps it is because we recognize
that there is a need for a genuinely prescriptive epistemological theory—
one that provides a framework for improving the reasoning of individuals
and institutions about significant issues. It’s not that skepticism and
other concerns of SAE are insignificant. But Standard Analytic Epistemology
so often ignores so much of the world that we do not believe
that the values implicit in its practice accurately reflect the values of its
proponents.
If improving the world is so important to you, why don’t you give up epistemology
and devote your lives to charity?
Our account of significance does not depend on a kind of maximizing
consequentialism. Significance ultimately is based on the conditions that
promote human flourishing, and given our physical and psychological
makeup, we take those conditions to be variable but also constrained. So
we would deny that people’s reasoning or action must always aim to
maximize some notion of the good.
On what grounds, then, can you criticize proponents of SAE for focusing
attention on skepticism? Let’s grant for the sake of argument that skepticism is
not the most significant problem facing epistemology. You admit that people
can be excellent reasoners even if they do not always address the most significant
problems. So your criticism of proponents of SAE depends on holding
them to standards you admit are unnecessarily high.
This objection fails to understand the nature of our criticism. We are
critical of epistemology as a field of study in the English-speaking world.
We are critical of the way resources (everything from human talent to
institutional support) are distributed in epistemology. We are happy to
grant that a healthy intellectual discipline can and should afford room for
people to pursue highly theoretical issues that don’t have any obvious
practical implications. So we do not object to any particular epistemologist
tackling the skeptical challenge. We object to the fact that proponents
of SAE insist (rightly) that epistemology has a prescriptive reason-guiding
function, while precious few resources are devoted to developing an
epistemological theory with useful prescriptive, reason-guiding advice.
Any epistemological theory worthy of the name must address the skeptical
challenge. The skeptic begins with a fund of presumptively justified beliefs and
proceeds to argue that one can’t legitimately make inferences that go beyond
that evidence. For example, a skeptic about the material world argues that on
