For some reason, there are some christians who find calling
Plantinga’s “Reformed Epistemology” by another name, namely “Deformed
Epistemology”, insulting. They called it
name-calling. I think that’s a little
unfair, so I’m going to put a little effort into defending the use of the term
“deformed epistemology”.
First, we need to look at what is being either reformed or
deformed – epistemology. This is what Wikipedia has to say (I’ve tidied up the list though):
Epistemology is the branch of
philosophy concerned with the theory of knowledge. Epistemology studies the
nature of knowledge, justification, and the rationality of belief. Much of the
debate in epistemology centers on four areas: the philosophical analysis of the
nature of knowledge and how it relates to such concepts as truth, belief, and
justification; various problems of scepticism; the sources and scope of
knowledge and justified belief; and the criteria for knowledge and
justification.
Alternatively, there is the Stanford Encyclopedia of Philosophy entry:
Defined narrowly, epistemology is
the study of knowledge and justified belief. As the study of knowledge,
epistemology is concerned with the following questions: What are the necessary
and sufficient conditions of knowledge? What are its sources? What is its
structure, and what are its limits? As the study of justified belief,
epistemology aims to answer questions such as: How we are to understand the
concept of justification? What makes justified beliefs justified? Is
justification internal or external to one's own mind? Understood more broadly,
epistemology is about issues having to do with the creation and dissemination
of knowledge in particular areas of inquiry.
There is also a Merriam-Webster dictionary entry:
the study or a theory of the
nature and grounds of knowledge especially with reference to its limits and
validity
Now I could go on adding text from the IEP (“Epistemology is
the study of knowledge”), other dictionaries (like dictionary.com:
“(epistemology is) a branch of philosophy that studies the origin, nature,
methods, and limits of human knowledge”), other encyclopedias (like Britannica:
“Epistemology (is) the study of the nature, origin and limits of human
knowledge”) and papers on epistemology (JT Tennis in Epistemology, Theory, and
Methodology in Knowledge Organization: “Epistemology is how we know”),
but I think the point has been adequately made already – epistemology is about knowledge.
If we are going to reform (or deform) epistemology, then we
are going to reform (or deform) something about how we interact with or think
about knowledge.
So, let’s look at Plantinga's deformed epistemology and
specifically his "proper functionalist version of epistemic
externalism" which he summarises in Warranted Christian Belief (p133):
Put in a nutshell, then, a belief
has warrant for a person S only if that belief is produced in S by cognitive
faculties functioning properly (subject to no dysfunction) in a cognitive
environment that is appropriate for S’s kind of cognitive faculties, according
to a design plan that is successfully aimed at truth. We must add, furthermore,
that when a belief meets these conditions and does enjoy warrant, the degree of
warrant it enjoys depends on the strength of the belief, the firmness with
which S holds it
Note that, according to Plantinga, knowledge
is warranted true belief rather than justified true belief:
That may not come as much of a
surprise, given that this book is a sequel to Warrant: The Current Debate and
Warrant and Proper Function. In the first of those books I introduced the term
‘warrant’ as a name for that property—or better, quantity—enough of which is
what makes the difference between knowledge and mere true belief.
So ... is there a problem with Plantinga's deformed
epistemology?
This might not come as a surprise, but I think there
is. Right off the bat, there is the assumption of a "design
plan". I understand that theists believe that there is, in some
sense, a design plan to humans. I do think it's possible to work
backwards from a belief in a god, including a belief that one's belief in a god
is a true belief and reach a belief that one has knowledge about
the existence of a god. Breaking it down a bit:
Is there a god?
Do you consider your belief to be a true belief?
Is there a truth (or god) detecting design plan in the human
brain?
Is your brain working in accordance with the design plan (or
is properly functioning)?
Does your belief with respect to god constitute knowledge?
Hopefully it can be seen that the only situation in which
Plantinga's deformed epistemology both matters and works is one in which:
1) there is actually
a god of the right sort,
2) there is actually
a design plan for brains such that, when functioning properly, they seek and
find truth (or detect the being that created the design plan),
3) the brain
of the theist is actually functioning properly in accordance with that design
plan, and
4) the
believer does actually have the correct sort of belief about the god that
exists.
If there is no god (or no god that fiddles with brains the
way that it would have to in order to ensure that humans accurately and
truthfully detect it), then Plantinga's argument falls in a big heap. Remember that Plantinga’s
“reformed epistemology” involves warrant, that warrant is that which “makes the difference between knowledge and mere true belief” and that a key element of warrant is that it involves “cognitive faculties functioning properly … according to a design plan”.
“reformed epistemology” involves warrant, that warrant is that which “makes the difference between knowledge and mere true belief” and that a key element of warrant is that it involves “cognitive faculties functioning properly … according to a design plan”.
Now, it cannot be that a belief in a god (or a particular
sort of god) is a “true belief” if there is no such god. However, it is conceptually possible that
that which “makes the difference between knowledge and mere true belief” could
exist even in the absence of a true belief so that a (false) belief that
nevertheless has this quality (“warrant”) could be described as a “rational
belief”.
Note that when you look for descriptions of “Reformed
Epistemology”, you invariably get referred to Plantinga and his attempts to
argue that religious belief may be rational.
IEP:
Reformed epistemology is a thesis
about the rationality of religious belief.
A section on reformed epistemology appears in the SEP, but
within the article on the Epistemology of Religion, an
article which makes it clear that it is concentrating on questions of the
justification of religious belief and ignoring questions as to whether “these
beliefs count as knowledge or whether these beliefs are scientific”.
So, it seems, “reformed epistemology”, despite Plantinga’s
protestations, isn’t about knowledge after all, but about the justification or
rationality of belief. It doesn’t really
qualify as epistemology at all, or rather it would qualify as epistemology if
and only if Plantinga’s god existed, which means he’s seriously begging the
question with his terminology.
Note that a not uncommon defence by theists is that reformed
epistemology is no more than the position that “belief in God, like belief in
other persons, does not require the support of evidence or argument for it to
be rational” (Kelly Clark, Without Evidence or Argument: A Defense of
Reformed Epistemology). So, when
challenged, they are more than willing to step back from the appearance of any
knowledge claim. But what they are not
stepping back from, and this is tricky bit, is the implication of a truth
claim.
Reformed epistemology might claim that a belief in a god may
be rational despite not having any evidence or argument in its support, but
this is entirely contingent on there being a god and the belief in that god
being true. This is why I call this
point of view deformed epistemology, it’s not really about knowledge at all,
just about justifying (or warranting) belief in a god in the absence of
evidence or convincing argument. And, to
the extent that it is an argument about knowledge (because Plantinga doesn’t
step away from implying that warranted true belief is knowledge), it’s both
begging the question and special pleading (because you can’t use the same
approach on other things you might want to believe and claim as knowledge).
