HOW
TO BE A RELIABILIST
Jonathan
L. Kvanvig
I.
INTRODUCTION
In
recent years, epistemologists have become increasingly impressed with reliabilist theories of justification.1 Reliabilism is often formulated as the claim that a belief
is justified2 just in case it is a reliable belief; however, this
formulation can be somewhat misleading. There is a sense in which a set of
beliefs can be reliable, just as a certain history or testimony can be reliable:
what one means is that a certain set of propositions is highly accurate, has
mostly true members, or is not wrong in any important
way. Reliabilists, though, do not just want to say
that a belief is justified just in case it is a member of a type with mostly
true members, i.e., just in case it is probably true; they also want to appeal
to the notion of reliability in that sense in which we say that persons,
processes, procedures, tests, and experiments are reliable. Reliabilism is a view both about the reliability of beliefs
and about the reliability of the person who has the belief or the procedure
that is responsible for the belief.
So,
we can distinguish two quite different central features of reliabilism.
The first is its connection with truth; according to reliabilists,
in order for a belief to be justified it must be objectively likely to be true.
Second, reliabilists claim that what makes a belief
probably true is the dependability either of the person holding the belief or
of the process or procedure by which the belief either comes to be held or is
(causally) sustained. Thus, we can distinguish personal reliabilism,
with its emphasis on the intellectual character of the person in question with
respect to accepting the truth and avoiding error, from procedural reliabilism, which emphasizes the efficaciousness of that
procedure with regard to generating truth and avoiding error.
The
notion of a process or procedure to which procedural reliabilists
appeal is often a historical notion: it involves some sort of temporal duration.We need not require temporal duration for a
version of procedural reliabilism; instead, I shall
merely require that any theory involving a procedural requirement not preclude
temporal duration. Hence, I shall construe the procedural requirement in a
quite weak sense: only a theory which insists that it is impossible that the
past affect justification denies the procedural requirement. So, for example,
coherence theories normally fail to include a procedural requirement since it
is normally present coherence that matters; causal theories, even those
emphasizing sustaining causes, include procedural requirements since causal
relations normally involve some time lapse (however minute).
Armstrong’s
theory provides a good example of personal reliabilism.
Armstrong claims that a person knows a truth when and only when there is a
law-like connection between the truth of the belief and the person’s holding
that belief.3 He calls this view a “thermometer” view of knowledge.
Some thermometers happen to register the correct temperature on a given
occasion, yet are defective. Such thermometers are to be likened to instances
of true belief which are not knowledge. Other thermometers are not defective
so that a certain reading on the thermometer insures that the temperature is as
the thermometer indicates. A person who knows is like a reliable thermometer:
his believing a proposition in a given circumstance insures that the
proposition in question is true.4 So, for
Armstrong, it is the person that is the locus of reliability.
Goldman
provides an excellent example of procedural reliabilism.
Goldman claims that a belief is justified if and only if it is produced by a
reliable method—a method which produces mostly true beliefs.5 On
Goldman’s view, the personal reliability of the individual is not important; a
person may be epistemically skewed so that it is only
a random occurrence that he uses a reliable method on any given occasion. Such
a person is clearly unreliable, yet the method he employs may itself be
reliable.
In
this paper, I wish to discuss how to capture the two sorts of intuitions that
lie behind reliabilist theories of justification: the
truth motivation (that a justified belief is one which is most likely true),
and the dependability motivation (that either the person or the procedure used
must be dependable in signalling truth). I shall
propose how to capture these intuitions, for I think they are important ones;
nonetheless, the way that these intuitions can be accommodated does not
generate a reliabilist theory of justification.
First, I shall suggest that the truth motivation can be captured only in a
derivative manner from a more fundamental theory of justification. Further,
even though the dependability motivation is an important insight into the
cognitive ideal, no such dependability requirement should be taken to be a
necessary condition for justification. Hence, I shall defend that having
justified beliefs is not the intellectual ideal, though it clearly is a part of
it. Let us begin with the truth motivation.
II.
JUSTIFICATION AND TRUTH
The
truth motivation, to repeat, claims that there must be some sort of objective
connection between the justification of a belief and the truth of that belief.
There is at least a grain of truth in these claims. In order to distinguish
between that sort of justification which is a merely practical justification
and that sort of justification—call it epistemic justification—which passes
one of the hurdles on the path from belief to knowledge, it would seem that we
must have reference to some connection between justification and truth which
does not obtain solely in virtue of the beliefs being held. One cannot say,
though, that an epistemicjustification is one that
best achieves the goal of believing the truth and avoiding error, for the best
way to achieve that goal is simply to believe the truth and not believe what is
false. The consequence of this statement is that there is no distinction
between justification and truth, hence a bit more care
is called for.
Suppose
we say, instead, that an epistemic justification obtains when holding the
belief in question achieves the goal of finding the truth and avoiding error
in virtue of some property that belief has other than being true. Such a view
is better than the earlier one, in that it does not simply collapse the
distinction between justification and truth. However, it is stronger than is
needed to capture the truth motivation for reliabilism,
for it would seem sufficient to capture that motivation that it is objectively
likely that holding the belief in question achieves the goal in question. Thus,
we might try:
J1:
Necessarily, S’s belief that p is epistemically justified
iff it is objectively likely that believing p best
satisfies the goal of believing the truth and avoiding error (in virtue of
having some property other than being true).
Call J1 an
objectivist account of epistemic justification, and contrast it with the
following subjectivist account:
J2: Necessarily, S’s belief that p is epistemically justified iff S
believes that believing p best satisfies the goal of believing the truth and
avoiding error.
J2 implies
that there is more to the connection between justification and truth than just
what obtains in virtue of S’s believing that p, for S
can believe that p and yet not believe that holding this belief best achieves
his goal of finding the truth and avoiding error. On the other hand, J2
obviously would not satisfy the truth motivation for reliabilism.
For the sort of connection that can obtain on J2 between justification and
truth does not require that anyone’s justified beliefs be true. J2 can be
satisfied even if all, or mostly all, beliefs are in fact false.
Consider another account of the
connection in question:
J3:
Necessarily, S’s belief that p is epistemically justified
if the property which makes S’s belief that p justified also makes the
following proposition justified for S: believing p best satisfies the goal of
finding the truth and avoiding error.
To see how J3
works, consider an example of a pragmatically justified belief: believing that
one will succeed in one’s endeavors on the grounds that if one does not believe
this claim, the lack of that belief is causally sufficient to insure failure. In
order for this justification to be epistemic justification, these same grounds
must justify the proposition that believing that one will succeed best satisfies
the goal of believing the truth and avoiding error. But surely these grounds do
not justify this latter claim: they don’t give any sort of reason whatsoever
for thinking that this latter claim is true or false.
I shall call this version of the
connection between justification and truth an iterative account of epistemic
justification. The defining characteristic of an iterative account is that it
denies that epistemic justification can be clarified solely by concepts other
than justification itself. Thus, any clarification will have a recurrence of
the same concept of justification both in the definiendum
and in the definiens.
Those that affirm the truth
motivation will not be any more satisfied with the iterative account than with
the subjective account. For the iterative account does not establish any sort
of objective link between justification and truth, any more than does the
subjective account. So, reliabilists cannot be happy
with J3 either.
One other possible approach to
distinguishing epistemic justification from other sorts of justification is to
take epistemic justification as primitive and define the other sorts of
justification in terms of this primitive notion. For example, one might be able
to define practical justification as that sort of justification which obtains
when and only when one is epistemically justified
that failing to do an action will frustrate one of one’s practical goals.6
But, even if such an account were to succeed, it would not satisfy the truth
motivation for reliabilism. For that motivation
requires that an epistemically justified belief be at
least objectively likely to be true, and this account does not imply that this
claim is true.
So, if the truth motivation is to be
affirmed, something like J1 must be acceptable. J1 is not acceptable, though;
for it is possible that there are means that get us to the truth and allow us
to avoid error which we reasonably reject. For example, it might be that
wishful thinking is a procedure which always gets us to the truth, even though
we quite rationally believe that it does not. On 11, those that engaged in
wishful thinking would thereby acquire justified beliefs, were wishful thinking
to get us to the truth. However, beliefs arrived at by wishful thinking are
prime examples of unjustified beliefs, hence we must reject J1.
There is a way, though, to avoid the
wishful thinking case and yet maintain some objective connection between
justification and truth. This can be accomplished by combining an objective
account with some other account. The general strategy is to accept:
J1a:
Necessarily, S’s belief that p is epistemically justified
iff p has some property in virtue of which it is
justified, and most beliefs which have that property are true.
J1a is an
objective account of the connection between justification and truth, since it
claims that a belief is justified if and only if it is most likely true. It
also appears to be a version of an iterative theory, since it appeals to the
notion of justification both in the definiendum and
the definiens. This appearance can be misleading
though, since a theory could include 11 a in addition
to giving either a subjective account of justification or taking justification
to be an undefined primitive. In any case, the definitive feature of J1a is
that it attempts to maintain the objective account by combining it with certain
features of other accounts. Further, it differs in how it handles the wishful
thinking case above, for since being the product of wishful thinking is not a
property which justifies beliefs, even if wishful thinking does generate true
beliefs, that is irrelevant on Jla. According to J1a,
only properties which both justify beliefs and signal the truth are relevant.
However, Jla
is not adequate either. The best way to see this is to take some instance of a
justification-conferring property—for example, consider beliefs arrived at
through perceptual processes. Such beliefs are ordinarily justified and are
also ordinarily true. Yet, such beliefs need not be true to be justified;
conditions can be abnormal (either external, environmental conditions or
internal problems with the perceptual mechanism) so that what appears to be
true is not what is true, and yet the rationality of beliefs arrived at by
perception not be undermined. This fact provides the clue to the inadequacy of
J1a. For suppose that, in the future, some highly skilled brain surgeon, in the
process of removing a brain tumor, alters the physical constituents of a
person’s perceptual apparatus thereby causing the person in general to have
false perceptual beliefs. Such perceptual beliefs can still be epistemically justified; nonetheless, those beliefs, though
justified, are not at all likely to be true.
One might think that my objection to
J1a rests on a too narrow specification of the property in virtue of which S’s
belief is justified. Instead of specifying the property as the property of
being produced by S’s perceptual apparatus, why not specify it as the property
of being produced by a perceptual apparatus?
Well, first, it is S’s perceptual
apparatus that produces the belief, not just any apparatus. But even if we
accept this alteration, it will not save J1a, for it is possible to generalize
the case in such a way that most perceptual apparati
mislead. Perhaps a nuclear war will occur in which very few will survive, and
almost all survivors need some sort of eye surgery. It might also be that the
surgeon who operates on the survivors alters their perceptual apparatus as
described above so that most all perceptual beliefs are false.
The last hope for defending J1a is
to point out that if one counts all the perceptual
beliefs over the entire history of the world, this attempt to generalize the
surgeon case may not imply that most perceptual beliefs over the entire history
of the world have been false. Yet, even this last attempt will not save J1a,
for the example can be generalized so that both the past and future are
constituted by mainly false perceptual beliefs. We are not without paradigms
here, for evil demon hypotheses and brain in the vat hypotheses abound. It
certainly seems possible that all of our appearance states are identical to
what they now are, that all of our beliefs are just as rational or justified as
they now are, and yet our beliefs be in general false
because of the activity of an evil demon or the fact that we are really just
brains in the vat.
And thus we end up back with
Descartes. The lesson here, I think, is that evil demon worries are not limited
to epistemologists with infallibilist leanings. Even
if we grant that it is irrelevant whether it is possible that we are wrong
about our beliefs, it does not follow that evil demon hypotheses are
irrelevant. For it is in virtue of granting that the
possibility of error does not undermine justification that this new evil demon
problem arises. For, once we grant that the possibility of an evil demon
does not matter to the justificatory status of belief, we ought also to grant
the obvious truth that even if we were in a world run by an evil demon, our
beliefs could be roughly as rational as they now are. Thus, to deny that the
possibility of error undermines justification does not entail that evil demon
worries are over: to anyone who accepts any objective version of the
connection between justification and truth, the same worries will arise all
over again.
Consider an example of a reliabilist aware of the problem evil demon hypotheses
raise. Goldman says,
“Suppose
that wishful thinking turns out to be reliable in the actual world!.. Let me.. try
to give a better rendering of our aim and the theory that tries to achieve that
aim. What we really want is an explanation of why we count, or would count,
certain beliefs as justified and others as unjustified. Such an explanation
must refer to our beliefs about reliability, not to the actual facts. The
reason we count beliefs as justified is that they are formed by what we believe
to be reliable belief-forming processes.. What
matters, then, is what we believe about wishful thinking, not what is true (in
the long run) about wishful thinking.”7
Goldman only
explicitly considers the wishful thinking case, but the wishful thinking
example is only a taste of things to come: it merely raises one sort of case
along the lines of evil demon hypotheses. In addition to wondering what to say
about other possible worlds where wishful thinking generates mostly truths,
there is the worry that our world is one in which wishful thinking is reliable.
And, in addition to the infallibilist’s worries about
other possible worlds run by evil demons, there is the worry which any
attempted preservation of the truth motivation must face: what if our world is
the possible world the infallibilists wondered about?
We should note that Goldman’s
response does not address the problem, rather it only
changes the subject. Instead of talking about justification and what is necessary
for it, Goldman changes the topic to a discussion of what we count as a
justified belief. How seriously he means to take this paragraph is not clear,
for he ignores it in the rest of the article.8 In any case, it is
clear that Goldman does not solve the evil demon problem here; he recognizes
that it is a problem and just choose to change the subject instead.
What I am suggesting is that the use
of evil demon considerations is a helpful way to see that the truth motivation
for reliabilism is problematic. Yet, it is important
to note here that I am not claiming that there is no connection between justification
and truth, nor even that there is not a necessary connection between
justification and truth; for we can take a lesson here from Descartes.
Descartes’ solution to evil demon worries is to argue that it is logically
impossible that there be such a world—it is logically impossible that there be
such a world since God exists, and a good God could not allow any error to
occur that we are not responsible for ourselves. Now, this latter claim is
probably too strong—I can see no reason to require that we have the capacity to
avoid error completely. Yet, the first part of the claim does seem right. A
perfectly good Being capable of creating beings that can actually find the
truth and avoid error could not remain faultless were He to create beings that
in general only found error. To be perfectly good requires,
first, being non-deceptive; but it also requires disclosing oneself and what
one knows. Now, this requirement is not that God tell us everything He
knows—perhaps in order to further our development, He just gives us the means
to find the truth. The search may be hard, but we, by struggling, do find it;
and we improve our intellectual characters in the process.
The strategy of such a solution to
evil demon worries is to formulate an instance of the following argument: if a
certain proposition p is true, then we are not in an evil demon world; p is
true; hence we are not in an evil demon world. Obviously, the critical premise
here is the claim that p is true; it must be is reasonable to accept that
premise, i.e., there must also be an acceptable theory of justification which
implies that necessarily, in certain conditions, believing p is reasonable.
The catch for the objective account of the connection between justification and
truth is that the justification provided for believing p by those conditions
must be independent of the existence or non-existence of an evil demon in order
to provide a philosophically adequate defense of the objectivity of a theory of
justification. For if the conditions under which believing p is reasonable are
dependent on whether there is an evil demon or not, we will not have an
adequate defense of objectivity unless we can reasonably believe, independent
of the existence of an evil demon, that the conditions
which make believing p reasonable obtain. (This is not to say, of course, that
believing p is not reasonable unless we can defend that the conditions in
question are independent of the existence of an evil demon—I am talking about
philosophical theories and their defense, not about justification.) The problem
for any objective theory is that the appeal of such theories to objective
likelihood seems intimately tied to the non-existence of an evil demon, for if
such a demon existed it would seem that what is objectively likely to be true
would be quite different than what it is (given that no evil demon exists).
Hence, it would seem, evil demon worries are unanswerable on purely objective
grounds alone.
It does not follow, however, that
objective theories are false, nor even that we lack good philosophical grounds
for accepting them. There is still the option that objective theories of
justification can be derivative theories of justification, i.e., that a
Cartesian-like response can be provided by some non-objective, fundamental
theory of justification which in turn implies that there is an objective
connection between justification and truth. The conclusion which is warranted
by our discussion is not that objective theories are inadequate, but rather
that if an objective account is to be acceptable, it must be accepted on the
basis of a derivation as suggested above from a more fundamental theory of
justification. Which theory that might be is an issue which will have to be
left for another time; the point that stands, though, is that there must be one
to overcome evil demon worries.
Further, seeing why the objective
account is inadequate as a fundamental theory about justification shows how
the circularity problem Descartes faces need not touch the account outlined
above. Descartes needed the existence of God to establish that his inference to
the existence of God was war-ranted; the above account need not face such a
difficulty precisely because whatever account of theory construction is
accepted, it must be independent of evil demon intrusions. The only question
there can be here is whether any such theory is possible; I think the answer is
yes, but I shall not defend that answer here.
Nor shall I be defending here that
believing that God exists is justified, for that is beyond the scope of this
paper as well.9 If that belief is justified, as I think it is, we
can formulate a defense of an objective connection between justification and
truth, for God’s existence gives us an answer to evil demon worries. It is,
after all, not possible that there is an evil demon; and, more generally, it is
not possible that justification and truth diverge in a manner contrary toil a,
since God exists. Thus, if one wants to know how to be a reliabilist,
the answer is simple: be a theist.
III. THE DEPENDABILITY REQUIREMENTS
The other major motivation for reliabilism is the dependability motivation, of which there
are two varieties: dependable persons and/or dependable procedures. The
personal dependability requirement is a stronger requirement than the
procedural dependability requirement. First, a person can be quite undependable
and yet on a given occasion employ a procedure which is quite dependable. It is
also true that a dependable person can employ an undependable procedure, yet if
a person is dependable he will normally employ dependable procedures; the
dependability of a procedure does not imply that it is normally used by a
dependable person.
Stronger requirements run a greater
risk of error, and such is the case here; I wish to argue that requiring
personal dependability results in a circularity problem for defenders of
personal reliability theories. Much about epistemology can be learned by
considering analogous issues in ethics, so let us begin there. There is an
important respect in which the moral ideal cannot be captured by any extensional
account of the particular acts that a person performs, has performed, and will
perform. For any extensional account of morality (an account limited in
reference to acts which are actually performed) cannot account for the fact
that we want persons to become disposed to do the right sorts of things. Given
any extensional account of morality, it will always be possible for a person
fortuitously to do all the right things, and yet be of despicable character.
We want persons to be virtuous, to have character, to be disposed to do the
right sorts of things; not only to do the right things.
But now consider what happens in
ethics if we not only agree that persons ought to have a certain sort of
character, but also insist that without such a character, they cannot do any
morally right acts. Presumably, the way we develop moral character is at least
partially through developing the right sorts of habits—by telling the truth
repeatedly, we acquire the habit, the virtue, of being honest. But, if we
defined proper behavior with theses virtues as a necessary condition for moral
rightness, our theory would be viciously circular. For we would have as a
necessary condition of moral rightness that virtues of a certain sort are
possessed, and we would also have that, in order to develop these virtues, we
must perform acts which are morally right.
There is an easy way out of this
dilemma, however, for one need not accept that the only interesting question
in ethics is the question “what sorts of acts ought I
perform?” We can quite readily grant that there are other questions and
problems worth addressing, and we can easily see that moral perfection involves
quite a bit more than just doing the right things. If we allow such an
extending of the sphere of ethics, we can grant that performing morally proper
acts is necessary for developing moral character without making the resulting
theory circular. We need only grant that, though proper moral character is a
necessary part of the moral ideal, having proper moral character is not a necessary
condition for performing a proper moral act.
There is much to be gained in
epistemology from this description of the project of ethics. Just as we need
not think in ethics that there is only one question that needs to be answered,
so in epistemology we ought to refrain from thinking that the only interesting
question concerns necessary and sufficient conditions for knowledge. The
intellectual ideal need not be seen as being captured by any extensional
account of knowing all truths, just as the moral ideal is not captured by any
extensional account of doing what one morally ought to do. Just as it is
important that persons develop their moral character, it is important that they
develop their intellectual character. Persons ought to be disposed to follow
the evidence wherever it might lead, to develop the habit of taking special
precautions in areas especially vulnerable to human fallibility; we need
persons who are able to clearly ascertain the implications of a body of data,
and to recognize what is significant in vast bodies of information; an
intellectually ideal person lacks intellectual laziness, he demonstrates
creativity and imagination, and he is careful to consider all the alternatives
available as well as to think up alternatives not yet known. But the
importance of these characteristics should not be confused with requiring
persons to have these traits in order to know, just as moral virtues are
important but not necessary for proper action. We can grant that having proper
intellectual character is a part of the intellectual ideal without insisting
that having such character is necessary for justification.
Of course, in both ethics and
epistemology, there are obvious connections between having the right sort of
character and having/doing the right sorts of beliefs/actions. For having
proper character entails being disposed to do the right sorts of things and
believe the right sorts of things. Thus, if a person is of the right sort of
character, it is more likely that he will in general do what is right and
believe what is epistemically supported than if he
does not have that sort of character. However, this sort of connection between
proper character and the epistemically justified is
only probabilistic, whereas the character motivation for reliabilism
insists on a necessary contiection between the two. But. as I have argued, to insist on a necessary relation
makes one’s account circular; for one develops a certain sort of character at
least partially by performing the right sorts of acts and by following the
evidence where it leads. Insisting on the necessary connection between the two
involves a certain sort of tunnel vision: thinking that the intellectual or
moral ideal is achieved when a person does all and only the right acts or when
all of his beliefs count as knowledge. There is no good reason to think that
that is all there is to either ideal, and there is plenty of reason to think
otherwise.
Not distinguishing the cognitive
ideal from what is necessary for justification causes improper evaluations of
particular cases. For example, consider a gypsy lawyer who is the lawyer of a
client accused of eight murders. The client admits having killed the first
seven but denies having murdered the eighth. Nonetheless, everyone in the
community, including the lawyer, is convinced that he is guilty of all eight.
As gypsies do, though, the lawyer consults the tarot cards, which say that his
client is innocent of the eighth murder. His gypsy nature then causes him to
believe what the tarot cards say, and what the tarot cards say causes the
lawyer to reexamine the evidence. Upon re-examining the evidence, however, the
lawyer clearly recognizes that the evidence, rather than confirming his
client’s guilt, completely exonerates him of the eighth murder. But, being of
rather impressionable character, the lawyer recognizes that if it were not for
the influence of the tarot cards, he would be unable to avoid being swayed by
public opinion both about what the evidence shows and about the guilt of his
client. Thus, the tarot cards are solely responsible both for the origination
and sustenance of his belief that his client is innocent.’0
Audi claims that, though there is a
justification for his belief, the lawyer’s believing is not justified (contrary
to Lehrer’s claims):
“(G)iven his faith in the cards, he would have believed p even
if it had been false, indeed, even if, on the basis of the cards, it had not
been rendered so much as objectively likely (to any degree) to be true, i.e.,
very roughly, likely to some degree given the actual facts relevant to p.... (This
point) strongly suggest(s) that S does not justifiably believe p. It is, after
all, simply good fortune (because the cards happened to be right) that S did
not believe something false in place of p. Surely if
one’s belief that p is justified by good evidence, it cannot be simply good
fortune that one did not believe something false instead.”’
Audi
claims that a person cannot justifiably believe a proposition if he just
happens to be lucky in having a belief for which he has adequate evidence. Yet,
whether a person is lucky or not is a matter of what sort of character that
person has; it is a matter of whether that person would believe the truth had
things been a little different. If Audi wishes to hold that proper character is
necessary for justification, he must tell us how we acquire such character
without appeal to forming justified beliefs.
Further, there are strong intuitive
grounds for rejecting Audi’s account of this case. What we ought to ask is
whether the gypsy lawyer knows that his client is innocent of the eighth
murder, and here I think the answer is clear: of course he knows that his
client is innocent (note what the lawyer could legitimately claim in response
to the amazement of the town at finding out the truth—he could quite rightly say,
“I knew it all along”). If we must go about purifying our motives before we can
ever know anything, most of us would know quite little, just as we could not do
much that is right if we were required to purify our motives in order to
perform a morally proper act. We can do the right sorts of things for the wrong
motives, and we can have knowledge even though what sustains our belief is not
what allows us to know.
What we immediately notice about the
gypsy lawyer is that something has gone wrong in his cognitive life; but
imputing this cognitive fault against his justified
belief only results by confusing justification with intellectual ideality. Just
as we can perfectly well grant that someone did the right sort of action even
though his character was somewhat marred (think of cases in which one
recognizes in oneself improper motives, but one decides that one ought to do
what one is improperly motivated to do anyway), one can have knowledge in a
certain case without requiring that one’s intellectual character be spotless.
The lawyer may even regret his inability to break his trait of trusting the
tarot cards; nonetheless, he knows in this case that what the tarot cards led
him to believe and sustain him in believing is true. Though he is in a less
than intellectually ideal relation to the proposition in question, the lack of
ideality concerns his intellectual virtues, not whether he has knowledge or
not.
So we can see that personal reliabilism has problems if the intuition that we want
persons to be reliable is taken to be a necessary conditon
for epistemic justification. But what of the weaker claim that reliable
procedures are necessary for epistemic justification? Don’t we have here a
necessary condition for epistemic justification, and thus isn’t some form of reliabilism true?
Procedural reliabilists
deny that what a person would believe in close counterfactual circumstances is
relevant to the justificatory status of the present belief. Counterfactual
cases are relevant, according to procedural reliabilists,
but it is counterfactual situations about the procedure, not the person, that
are important. One way to understand this position is to see it as a retreat
from personal reliabilism in the face of the
difficulties above. Since we cannot coherently require that a person have a
proper cognitive character in order to have a justified belief, we must retreat
to a more minimal claim that the person must instance (in the actual
circumstance) what would be proper character if the person in question were
usually to proceed in that fashion. The requirement that the person normally
proceed in that fashion is dropped; what remains is the requirement that the
procedure be one that a person of good cognitive character would employ.
When understood in this way, though,
it is far from obvious why a procedural requirement is necessary for justified
belief. We saw earlier that proper cognitive or intellectual character is part
of the intellectual ideal; hence, so is exhibiting such a character in a given
circumstance. Yet, if having a proper intellectual character is not necessary
for justification, why should exhibiting it in a given circumstance be? To
appreciate my puzzlement, recall that central to the procedural requirement is
temporal duration. To require that proper procedure is followed allows that
facts solely about the past can imply that one’s present belief is unjustified.
Again, consider ethical analogies. One’s past conduct can affect which options
are presently available to one, but which of those options is preferable is a
matter of their present moral worth. Suppose a person has a thoroughly
despicable past, but suddenly has a change of heart and begins to act differently.
Clearly, some actions he could have done had he behaved differently in the past
he will not be able to do; perhaps if he had been more careful in the past, he
would not be so sick that he can do nothing but lie in bed and recover while
his family suffers because of his inability to work. Yet, we should not say
that he is now behaving improperly by not getting out of bed and going to work.
What he should do now depends on what he is capable of doing now, and which of
the available options is presently superior on moral grounds.
The same point holds for epistemic
matters as well. We may follow procedures that damage our overall chances of
finding the truth and avoiding error; yet what is relevant at a particular time
is not these overall chances but rather what the present circumstances
indicate. Even in inductive cases, where the past seems to be relevant to
present justification, it is not strictly the past that is relevant, but
rather our present memory of past cases like the present one that determines
the justificatory status of belief (or perhaps the present fact that we should
recall and take into account certain information about the past that makes a
belief less than rational). The gypsy lawyer case is as instructive here as it
was with regard to a character requirement. The procedure which produces and
sustains his belief (namely, reading the tarot cards) is clearly unreliable,
yet he has knowledge. How? Presumably in virtue of his (present) awareness of
the evidence and what it shows.
The lesson here is simple. If having
a proper intellectual character is not required to have a justified belief,
there is no reason to think that following a procedure that would be followed
by one with a proper intellectual character is required either. One’s
procedures prior to t are simply not relevant to what the circumstances at t
show to be true or false; it is what the circumstances at t show that is
relevant to what one ought to believe.
One way to express the lessons of
cases like the gypsy lawyer case employs the notion of epistemic luck.
Procedural reliabilists grant that some epistemic
luck is possible, for a person can just happen to employ proper procedure on a
given occasion and yet have knowledge. In. allowing this sort of luck, procedural reliabilism
avoids the circularity problem faced by personal reliabilism.
What gypsy-lawyer-like cases show is that an even greater sort of epistemic
luck is possible: a person can have a belief produced and sustained by a faulty
procedure which just happens to be an instance of knowledge as well. The
distinction between the intellectual ideal and justification provides an
explanation for this phenomenon of epistemic luck.12
We have been thinking of procedural reliabilism as a sort of limiting case of personal reliabilism: the
procedure is proper if and only if it is one that a reliable person would use.
Yet, we can now see that even if we think of the procedural requirement as
completely independent of the character requirement, there is no reason to
take it to be necessary for justification. Again, it is clearly part of the intellectual
ideal that we follow proper procedures; I tend to think that this is so because
it is part of the intellectual ideal that we have proper cognitive characters.
But even if the procedural requirement is independent of the character
requirement, its being a part of the intellectual ideal should not prompt us to
think that it is a necessary condition for justification. The past is
irrelevant to what is presently shown to be true.
IV. CONCLUSION
Both the truth motivation and the
dependability motivation deserve a place in any acceptable epistemology; the
difficulty with reliabilism is not
knowing where to put the elements that satisfy these motivations. The
truth motivation can, at best, be satisfied by a more fundamental theory of
justification than reliabilism, for directly
satisfying that motivation results in a theory burdended
by counterexamples. In addition, epistemological questions are questions
regarding the cognitive or intellectual ideal, and the dependability motivation
for reliabilism is clearly an important motivation to
satisfy in any adequate account of the cognitive ideal. Developing a theory of
justification, however, which satisfies the dependability motivation results
from confusing whether a person is cognitively ideal with whether a person has
a justified belief.
A complete epistemology will include
elements which satisfy the motivations for reliabilism;
however, the way in which these motivations are satisfied will be quite
different than reliabilists have imagined. Put quite
negatively, in order to satisfy reliabilist
motivations, one ought not to be a reliabilist at
all.

2. My use of ‘justification” here is
independent of any theoretical commitments. I use it as a place-bolder for a
condition necessary for knowledge in addition to true belief (and perhaps some
condition to handle Gettier and Gettier-like
counterexamples) Thus, I am not, on this basis, in disagreement with tbose that claim that justification is not necessary for
knowledge (unless they mean to imply that only true belief is).
