ABSTRACT. A case is made for a moderate version of form of epistemic externalism about
knowledge. It is argued that the general structure of knowledge is along the lines set out by
anti-risk virtue epistemology. Since such a proposal makes no essential demand that one’s
cognitive success be significantly supported by reflectively accessible rational support,
epistemic externalism about knowledge results. Nonetheless, anti-risk virtue epistemology
offers an account of knowledge that is entirely built around a conception of cognitive
responsibility. This ensures that it is able to accommodate supposedly internalist intuitions
about the relationship between knowledge and cognitive responsibility. Moreover, it is argued
that this proposal is entirely consistent with the idea that the knowledge possessed by
cognitively developed agents characteristically involves a significant level of reflectively
accessible rational support. Indeed, it is claimed that not only does the knowledge possessed
by cognitively developed agents enjoy such rational support but also, in line with epistemological
disjunctivism, that such reflectively accessible rational support will also often include factive
reasons. It is argued that far from being in tension with epistemic externalism about
knowledge, epistemological disjunctivism offers a compelling way for a moderate epistemic
externalism to account for the role of reasons within knowledge. The resulting account of
knowledge, while essentially a form of epistemic externalism, can thus nonetheless incorporate
many of the considerations that drive the adoption of epistemic internalism about knowledge.
1. MAPPING THE TERRAIN
Let’s begin by defining terms. Call an epistemic condition any necessary condition for knowledge, in
addition to true belief (where it is left open how many epistemic conditions there are). I will take
epistemic internalism about knowledge to consist in the claim that a necessary condition for knowledge is
that one’s belief in the target proposition satisfies an internalist epistemic condition. Epistemic
externalism about knowledge will thus consist in the denial of this claim, and thus amounts to the
2
thesis that one can have knowledge without satisfying an internalist epistemic condition. I will
understand an internalist epistemic condition, in turn, as a condition on knowledge which demands that
the subject has reflectively accessible reasons for believing the target proposition to be true.1 An
externalist epistemic condition will thus be any condition on knowledge which does not involve this
demand.
This way of thinking about the epistemic internalist/externalist distinction and its
application to the theory of knowledge is, of course, at least partly stipulative, but I think it
nonetheless broadly captures some important distinctions in post-Gettier epistemology. In terms
of this framework, for example, we can consider the classical tripartite account of knowledge as a
particularly pure form of epistemic internalism about knowledge, in that satisfying an internalist
epistemic condition (justification, classically understood) is not only necessary for knowledge but
also, with true belief, sufficient (i.e., there is only epistemic condition on knowledge, and it’s an
internalist epistemic condition).2 Post-Gettier, however, the interesting battleground regarding
knowledge is between impure forms of epistemic internalism (i.e., which have a necessary
internalist epistemic condition, but which also include external epistemic conditions) and epistemic
externalist proposals which reject the need for an internalist epistemic condition altogether (such
as process reliabilism as applied to knowledge).3
With the foregoing description of the topography of the epistemic externalism/internalism
debate in mind, I will be arguing for three main theses. First, I will be articulating an externalist
account of knowledge in general that I call anti-risk virtue epistemology. In particular, I will be
explaining how this view can offer us a robust way of understanding the manner in which
knowledge requires cognitive responsibility without thereby demanding that the subject’s belief
satisfies an internalist epistemic condition.
Second, I will be arguing that even if one embraces anti-risk virtue epistemology¾and
thus epistemic externalism about knowledge in general¾that is entirely consistent with holding
that the knowledge possessed by cognitively developed agents often satisfies an internalist
epistemic condition. In particular, I will be contending that paradigmatic forms of perceptual
knowledge in fact satisfy a particularly robust rendering of the internalist epistemic condition, by
involving a supporting reason that is factive (i.e., which entails the believed proposition that it is a
reason for). This position is known as epistemological disjunctivism.
Third, I will maintain that not only is epistemological disjunctivism compatible with an
externalist account of knowledge like anti-risk virtue epistemology, but that the role it offers for
factive reasons within a theory of knowledge is crucial to making sense of how rational support
relates to knowledge within an externalist account. The alternative, as I explain, is a conception of
3
rational support that runs in parallel to the kind of cognitive responsibility captured by epistemic
externalism, but which is ultimately disengaged from it. What we need to make sense of is how, in
the right epistemic conditions, the rational support we have for our beliefs is no less hooked up to
the world than the externalist epistemic support that these beliefs enjoy.
2. TWO KINDS OF COGNITIVE RESPONSIBILITY
The attraction of epistemic internalism about knowledge lies in the notion of cognitive
responsibility. If one’s knowledge doesn’t satisfy an epistemic internalist epistemic condition, such
that one has good, reflectively accessible, reasons in support of one’s belief, then in what sense is
one’s knowledge really attributable to one’s cognitive agency at all? This point becomes especially
clear if one focusses on an austere form of epistemic externalism about knowledge, such as
process reliabilism. If reliability is a route to knowledge, regardless of whether one has reasons
available to one in support of the target proposition—including regarding whether one’s belief is
formed via a reliable process—then in what sense does this knowledge have anything to do with
one’s exercise of cognitive agency? Indeed, couldn’t it just as well be a matter of brute luck that
one knows, at least from one’s own perspective, in that one has simply chanced upon a true belief
via a reliable process?4
In contrast, if one’s true belief is grounded in good reflectively accessible reasons, then it
plausibly is now attributable to one’s cognitive agency, as one is able to offer an appropriate
account of why one regards the proposition as being true. Note that given we are working, postGettier, with at most impure epistemic internalism about knowledge, then there is no pretense that
such reasons would entail the truth of the target proposition, or otherwise would suffice (in
conjunction with true belief) for knowledge by themselves. One is thus still to some extent
hostage to the kind of external factors obtaining that are at issue in the relevant external epistemic
conditions in play. Nonetheless, so the thought goes, what’s important for knowledge is just that
one can tell such a story about cognitive agency, and that epistemic internalism about knowledge is
uniquely placed to capture this insight.
I don’t want to deny the importance to our epistemic framework of reflectively accessible
reasons. Indeed, as already indicated, I think that often we are in possession of such reasons of a
very special kind, in that they actually entail the truth of the target proposition. But my current
interest is in the idea that epistemic internalism about knowledge is the only game in town when it
comes to accounting for the importance of such reasons. In particular, I want to suggest that the
notion of cognitive responsibility in play here is in fact much broader than the epistemic internalist
4
would have us believe.
That there is such a broader notion of cognitive responsibility is an insight that we gain
from virtue-theoretic accounts of knowledge. The contrast between process reliabilism and virtue
reliabilism is a case in point. We can take the latter to be essentially a refinement of the former.
One of the key problems that afflicts process reliabilism is that it treats any reliable belief-forming
process as knowledge-conducive, and yet some reliable belief-forming processes appear to have
nothing whatsoever to do with knowledge. Consider, for example, Alvin Plantinga’s (1993a, 19598) famous case of the brain lesion that causes the agent concerned (who is oblivious as to the
causal processes in play) to reliably form a true belief that she has a brain lesion. Getting to the
truth in this way looks very much like dumb luck. The crux of the matter is that the reliability of
this belief-forming process seems irrelevant to knowledge because it has nothing to do with the
subject’s cognitive agency. Indeed, this scenario concerns a malfunction of one’s cognitive agency, in
that it is despite one’s cognitive agency that one ends up forming a true belief via a reliable process.
Virtue reliabilism aims to avoid the problems posed by cases like this by restricting the
class of reliable belief-forming processes that are relevant to knowledge. In particular, it is not true
belief formed via any reliable belief-forming process that puts one into the market for knowledge,
but only those skill-like reliable belief-forming processes that are integrated within one’s cognitive
character, and which are thus manifestations of one’s cognitive agency. We can thus explain why
one’s reliable faculties and cognitive skills can be knowledge-conducive while brain lesions and
such like, even when they generate a reliable belief-forming process, are not knowledgeconducive.5
The general point in play here is that knowledge demands cognitive responsibility at least
in the following sense: that one’s cognitive success (i.e., true belief) is significantly creditable to
one’s cognitive agency. This means that one’s cognitive agency is playing a significant role in the
causal explanation of one’s cognitive success. Call this veritic cognitive responsibility. Merely forming
one’s true belief in a reliable way doesn’t suffice in this regard, as one’s cognitive success might
have nothing to do with one’s manifestation of cognitive agency, as when the reliability in question
arises out of a cognitive malfunction rather than a cognitive skill. In contrast, when one gets to the
truth by employing one’s reliable cognitive traits that are integrated into one’s cognitive
character—and thus count as one’s cognitive skills—then one’s cognitive success is significantly
attributable to one’s cognitive agency.
The reason why veritic cognitive responsibility is important for our purposes is that we are
capturing a notion of cognitive responsibility which doesn’t essentially trade in reflectively
accessible reasons. Imagine for a moment a subject whose perceptual faculties are functioning
appropriately in suitable cognitive conditions, and hence is reliably forming true beliefs as a result,
5
but who lacks reflectively accessible grounds in support of her beliefs. What’s interesting about
such a case is that it looks very different to someone merely coming across the truth through
dumb luck. The point is that getting to the truth via dumb luck has nothing to do with one’s
manifestation of cognitive agency. In contrast, when one appropriately employs one’s cognitive
skills and gets to the truth as a result, then one’s cognitive success is significantly attributable to
one’s cognitive agency, even if one lacks reflectively accessible grounds in support of the target
belief. It follows that veritic cognitive responsibility captures a general kind of cognitive
responsibility that doesn’t essentially appeal to the possession of reflectively accessible reasons.
Notice that in stating the foregoing one need not be claiming that the possession of
reflectively accessible reasons is unimportant to knowledge. The point is just that one can have
knowledge, and hence exhibit a sufficient level of cognitive responsibility for knowledge, without
being in possession of such reasons. In fact, when it comes to cognitively developed agents, I
think it is clear that our beliefs tend to go hand-in-hand with the possession of reflectively
accessible reasons. Indeed, to stand in the ‘space of reasons’ in this way is a core part of what it is
to be a cognitively developed agent. But while the possession reflectively accessible reasons might
normally be the case, it’s not a requirement of knowledge, even though it is a requirement of
knowledge that it demands veritic cognitive responsibility.
Moreover, notice that while the possession of reflectively accessible reasons is unnecessary
for the kind of veritic cognitive responsibility that knowledge demands, it doesn’t follow that the
possession of such reasons has no bearing on one’s cognitive responsibility. Quite the contrary:
one will usually manifest higher levels of cognitive responsibility by in addition possessing such
reasons. Consider our agent forming her true beliefs through the employment of her reliable
cognitive abilities, while lacking reflectively accessible reasons in support of what she believes.
Wouldn’t her cognitive success be attributable to her cognitive agency to a higher degree if she
also comes to possess good reflectively accessible reasons that align with her manifestation of
cognitive ability, such as by becoming aware of her track-record of success in this regard? The
point is that in denying the necessity of reflectively accessible reasons for the kind of veritic
cognitive responsibility required for knowledge one is not thereby denying that such reasons can
often play an important role in determining whether, and to what extent, one exhibits such
cognitive responsibility.
It follows that even an epistemic externalist about knowledge ought to not only be willing
to grant that the knowledge possessed by cognitively developed agents involves the satisfaction of
an internalist epistemic condition, but will also prize the possession of reflectively accessible
reasons, as it can ensure a higher level of cognitive responsibility. What makes one an epistemic
externalist is just that one doesn’t hold that satisfying an internalist epistemic condition is required
6
for knowledge. In particular, one’s true belief can exhibit the kind of veritic cognitive responsibility
required for knowledge without satisfying such an epistemic condition.
3. ANTI-RISK VIRTUE EPISTEMOLOGY
In the last section I argued that knowledge demands veritic cognitive responsibility. In this section
I want to argue that knowledge doesn’t just demand veritic cognitive responsibility, but also a
stronger kind of cognitive responsibility, albeit where this stronger notion still falls short of
demanding reflectively accessible grounds (and hence doesn’t lead to epistemic internalism about
knowledge either). The stronger thesis that I have in mind is that one’s safe cognitive success is
significantly attributable to one’s cognitive agency. Call this safe cognitive responsibility. Moreover, safe
cognitive responsibility amounts to a complete account of knowledge, one that is thus both
epistemic externalist and centrally concerned with cognitive responsibility. I call this theory of
knowledge anti-risk virtue epistemology.6
Safety demands that one’s cognitive success, so formed, could not have easily been a
cognitive failure (i.e., false belief).7 Put another way, there is not a close possible world where one
forms one’s belief on the same basis as in the actual world and one’s belief is false. In earlier work
I have motivated this constraint on knowledge in terms of a methodology that I called anti-luck
epistemology.8 Roughly, one first offers an account of luck, then one offers an account of the specific
sense in which knowledge is incompatible with luck, and then one puts the two parts together to
articulate an anti-luck condition on knowledge. To this end, I offer a modal account of luck and a
specification of the veritic epistemic luck that’s inconsistent with knowledge, and this leads directly
to the safety condition. We thus have an independent motivation for this constraint on
knowledge.9 These days I make the same point by appealing to risk rather than luck, and hence we
get anti-risk epistemology. The details behind the switch aren’t important for our purposes; what is
important is rather the guiding idea that knowledge is incompatible with a high degree of epistemic
risk, and that this is captured by safety.10
That knowledge demands safety is widely accepted in the literature, and we’ve already
witnessed the rationale for thinking that knowledge demands veritic cognitive responsibility.11 But
why would it be important to knowledge that it in addition demands safe cognitive responsibility?
We can understand why by considering two kinds of cases: (i) veritic cognitive responsibility
involving an unsafe true belief; and (ii) veritic cognitive responsibility involving a safe true belief,
but where one’s safe cognitive success is not significantly attributable to one’s cognitive agency.
We will take these cases in turn.
7
In order to understand what is at issue in (i), we first need to introduce a distinction
between two ways in which a success can be unsafe, and thus high risk: intervening risk and
environmental risk.12 Consider an archer who skillfully fires an arrow at a target, and who hits the
target. The twist in the tale, however, is that a dog playfully jumped up and caught the arrow midflight and placed it in the target. We thus have skillful agency on display and also a successful
outcome, but where the success could very easily have been a failure (e.g., had the dog run off with
the arrow instead), and hence is unsafe. This is a case of intervening risk, in that something
intervenes between the skillful attempt and the successful outcome, such that there was a high risk
of failure. In cases of intervening risk, the success is not significantly attributable to the subject’s
skillful agency, but is rather attributable to the intervening factor, in this case the contribution of
the playful dog.
But consider now a corresponding case of environmental risk. We run the case just as
before, except that now instead of the dog playfully grabbing the arrow in mid-flight, he instead
narrowly fails to catch it. The arrow therefore passes the dog and goes on to hit the target. We
thus have skillful agency on display and also a successful outcome. While there is no intervention
in this case, the subject’s success is still unsafe, given how the dog could very easily have
intervened; there was still a high risk of failure. This lack of safety is, however, due to
environmental factors rather than because of anything intervening between the skillful attempt and
the successful outcome. Interestingly, unlike cases of intervening risk, the success in this case is
significantly attributable to the subject’s skillful agency, even though it is unsafe. The point is that
one’s success can be modally fragile and yet no less attributable to one’s agency, at least so long as
nothing in fact intervenes between the skillful attempt and the successful outcome.13
This contrast between intervening and environmental risk manifests itself in epistemic
cases. Intervening epistemic risk will be familiar from standard Gettier-style scenarios, as these
usually involve the combination of cognitive skill and cognitive success, but where something
intervenes to ensure that the latter is not attributable to the former. (Consider, for example, the
famous ‘sheep’ case, where the farmer sees what he thinks is a sheep in the field, and so truly
believes that there is a sheep in the field, but he is in fact looking at is a big hairy dog, which is
obscuring from view the genuine sheep behind).14 In contrast, environmental epistemic risk is
found in the barn façade case and other non-standard Gettier-style cases that have a parallel
structure.15 Recall that the subject genuinely sees a barn in this scenario, but that her cognitive
success is nonetheless unsafe because she happens to be in an environment in which what looks
like a barn is normally a barn façade.
We get the same contrast between intervening risk and environmental risk in the epistemic
cases as in the non-epistemic examples just considered. In the former, the intervening epistemic
8
risk ensures that the subject’s cognitive success is no longer significantly attributable to her
cognitive agency. In contrast, in cases of environmental epistemic risk the subject’s cognitive
success is significantly attributable to her cognitive agency, even though it is unsafe. Neither case
amounts to knowledge, even the case of environmental epistemic risk where the subject exhibits
veritic cognitive responsibility.16 The natural explanation for this is that the cognitive success is
unsafe (and thus epistemically risky) in both cases, as the subject’s belief-forming process could
have easily resulted in a false belief. Knowledge is, however, incompatible with high levels of
epistemic risk, which is why it demands safety. We can thus see why veritic cognitive responsibility
involving an unsafe true belief, as in cases of environmental epistemic risk, doesn’t amount to
knowledge.
Note, however, that this conclusion needs to be properly understood. In particular, as it
stands it might be thought that the way to resolve the issue would be to demand that knowledge
requires veritic cognitive responsibility and, in addition, safety. But this would be a mistake. In
particular, while knowledge does demand both veritic cognitive responsibility and safety, these are
not to be understood as distinct constraints on knowledge.
We can see this point by considering cases that fall under (ii), such that there is veritic
cognitive responsibility involving a safe true belief, but where the subject’s safe cognitive success is
not significantly attributable to her cognitive agency. Consider the following variation on the barn
façade case. In this scenario we keep everything fixed from before except that we add a helpful
demon who is determined to ensure that the subject’s forms a true belief in this regard. In
particular, while the subject in fact looked at a genuine barn, had she instead opted to look at one
of the fake barns in the vicinity, then the helpful demon would have instantly switched it for a real
barn to ensure that the subject’s belief remains true. The environmental epistemic risk is thus
cancelled out by the helpful demon, and the subject’s belief is hence nonetheless safe (even though
the helpful demon does not in fact do anything).17
As with the original barn façade case, the subject’s cognitive success is significantly
attributable to her cognitive agency (and hence it manifests veritic cognitive responsibility), as it
remains true that nothing has intervened between the skillful formation of belief and cognitive
success. Moreover, the belief is in addition safe, thanks to the watchful eye of the helpful demon,
as given how the belief was formed this is not a cognitive success which could have easily been a
cognitive failure. And yet the belief is no more a candidate for knowledge than the original barn
façade belief. Furthermore, the natural diagnosis for why this is so is that the safety of the
cognitive success has nothing at all to do with the subject’s manifestation of cognitive agency, but
is rather solely the result of the presence of the helpful demon. In particular, what is lacking in this
case, unlike in genuine cases of knowledge, is that the subject isn’t exhibiting safe cognitive
9
responsibility, but merely the combination of safety and veritic cognitive responsibility.
Understanding knowledge in terms of safe cognitive responsibility, as anti-risk virtue
epistemology proposes, offers us a complete externalist theory of knowledge, in that it captures all
cases. It would obviously take us too far afield to defend this claim in full here, but let me at least
give the reader a flavor of the considerations in its favour by comparing it to a recent account of
knowledge that is broadly cast along the same lines (and which is also a form of epistemic
externalism).18 According to this proposal, which I have elsewhere called robust virtue epistemology, we
should understand knowledge as demanding a strong version of veritic cognitive responsibility,
whereby the agent’s cognitive success should be primarily, rather than merely significantly,
attributable to the agent’s cognitive ability.19 In particular, the thought goes that this addition
enables one to do without having an anti-risk condition on knowledge like safety, as the stronger
explanatory relation will itself suffice to exclude high levels of epistemic risk.
This proposal doesn’t work, however. On the one hand, the cases involving environmental
epistemic risk that we have already looked at pose a problem for this view. For not only is the
subject’s cognitive success significantly attributable to her cognitive agency in these cases, but it is
also primarily attributable too, given that nothing intervenes between the skillfully formed belief
and the cognitive success. Indeed, in the barn façade scenario, where one is looking at a genuine
barn, one is in fact doing everything one needs to do in order to be able to correctly identify it as a
barn. Accordingly, robust virtue epistemology is committed to treating the subject as having
knowledge, even despite the high levels of epistemic risk involved.20
The problem of environmental epistemic risk illustrates that robust virtue epistemology is
too weak, in that it treats some beliefs as being knowledge even though they aren’t. The proposal
is also too strong, however, in that it excludes some genuine cases from being knowledge. The
crux of the matter is that we are often epistemically dependent on others, such as in testimonial
cases where our cognitive success is at most only significantly attributable to our cognitive agency.
The familiar example in this regard is of someone in good epistemic conditions gaining a true
belief via testimony from a knowledgeable informant. Since gullibility is not a route to knowledge,
one will expect the manifestation of a certain level of cognitive agency on the part of the subject,
such that she is careful about who she asks for information, and suitably critical about the
information that she is given. If she gains a true belief as a result, this should suffice for veritic
cognitive responsibility, as the cognitive success will be significantly attributable to her cognitive
agency. But given that she gained this true belief by, for the most part, trusting a knowledgeable
informant, we would surely not regard her cognitive success as being primarily attributable to her
cognitive agency, as that would be to negate the important contribution of the informant to this
cognitive success.
10
Robust virtue epistemology is thus both too strong and too weak, and this combination of
difficulties makes it hard to respond to these objections, as whatever it does to answer one of the
charges will make it more difficult to respond to the other.21 In recognizing the problems that face
robust virtue epistemology, it becomes clearer why anti-risk virtue epistemology is so attractive.
On the one hand, we’ve already seen that this proposal can deal with cases of
environmental epistemic risk, like the barn façade case. Indeed, it can also deal with related cases
like the helpful demon who underwrites the safety of the belief and thereby cancels out the
environmental epistemic risk, since in such cases the agent doesn’t exhibit safe cognitive
responsibility. The crux of the matter is that veritic cognitive responsibility doesn’t suffice for
knowledge, unlike safe cognitive responsibility.
On the other hand, however, since anti-risk virtue epistemology only demands that that
the subject’s cognitive agency should play a significant, rather than primary, explanatory role, then
it can also deal with scenarios involving epistemic dependence, like the testimonial case that we
just looked at. In particular, while these scenarios involve the subject manifesting not merely
veritic cognitive responsibility but also safe cognitive responsibility—for if they didn’t involve the
latter, then they wouldn’t be plausible cases of knowledge—they only demand that the subject’s
cognitive agency plays a significant role, and not also a primary one.
The comparison with robust virtue epistemology also highlights the importance of how one
strengthens veritic cognitive responsibility to formulate a theory of knowledge. What’s required is
not to strengthen the explanatory relation within veritic cognitive responsibility, but rather to shift
from veritic cognitive responsibility to the more demanding safe cognitive responsibility, while
keeping the explanatory relation in play fixed. Interestingly, either strengthening preserves the
epistemic externalism of the account of knowledge that results. Indeed, even if we opted for a
theory of knowledge that opted for both kinds of strengthening—i.e., the shift to safe cognitive
responsibility and a strengthening of the explanatory relation—the resulting account of knowledge
would still be recognizably externalist since it makes no demand for reflectively accessible reasons.
The upshot is that the notion of cognitive responsibility that we are articulating is independent of
epistemic internalism. Insofar as part of the motivation for epistemic internalism arises from a
desire for our knowledge to demand a robust notion of cognitive responsibility, we are thus in a
position to partly accommodate internalist intuitions without thereby embracing epistemic
internalism itself.
Nonetheless, there is nothing in anti-risk virtue epistemology that excludes the possibility
that most of one’s knowledge—indeed, potentially all of it—satisfies an internalist epistemic
condition. Indeed, in the most straightforward case, one would expect cognitively developed
agents to satisfy this rubric via their possession of reflectively accessible grounds. Anti-risk virtue
11
epistemology is thus entirely compatible with a moderate epistemic externalism about knowledge.
4. EPISTEMOLOGICAL DISJUNCTIVISM
I just noted that anti-risk virtue epistemology is compatible with agents nonetheless having
knowledge that satisfies an internalist epistemic condition. Interestingly, it is in addition
compatible with there being certain kinds of knowledge that satisfy such a condition in a
particularly full-blooded manner. This is where epistemological disjunctivism comes into the
picture. According to this proposal, perceptual knowledge in epistemically paradigm conditions
involves reflectively accessible support that is factive, in the sense that it actually entails the target
proposition that is believed. The epistemically paradigm conditions in question concern one’s
veridical perception being the result of one’s perceptual faculties functioning appropriately in
epistemic conditions that are both objectively and subjectively good. This means that not only is
the subject in epistemic conditions that are in fact ideal for the subject to gain perceptual
knowledge, but that the subject is also appropriately basing her belief on this factive reason (e.g.,
there are no misleading defeaters in play that she is disregarding). Epistemological disjunctivism
claims that in these conditions one’s perceptual knowledge that p can be rationally supported by
the factive reason that one sees that p (where seeing that p entails p), and where one’s rational
support is no less reflectively accessible for being factive.22
Such a proposal is controversial, and one can understand why. It has hitherto largely been
taken as given in contemporary epistemology that reflectively accessible rational support must be
by its nature non-factive. This point is often thought to be illustrated by appeal to radical sceptical
hypotheses, such as the brain in a vat scenario. The thought goes that one’s envatted counterpart,
who seems to be experiencing the world in exactly the same way (albeit non-veridically, as she is,
unbeknownst to her, trapped in the vat), has exactly the same rational support available to her as
one does. If that’s right, then of course one’s rational support must be non-factive, as it is
consistent with the target beliefs being false.23 In contrast, epistemological disjunctivism rejects
this line of argument, and maintains that the reflectively accessible rational support available to
subjects in ‘good’ cases (i.e., where conditions are epistemically paradigm) can be different in kind
from the reflectively accessible rational support available to subjects in experientially
indistinguishable ‘bad’ cases (e.g., as when one is the victim of a radical sceptical hypothesis). In
particular, in the former case the agent can be in possession of factive reasons, even though the
agent in the latter case only has, at most, non-factive reasons available to her. And this is so even
though the subject has no discriminative capacity to tell these two cases apart.
12
Epistemological disjunctivism, if credible, has many attractions, as even its detractors
usually acknowledge (their complaint is rather that it isn’t credible). Perhaps the chief attraction is
the very direct way it offers us of dealing with radical scepticism, at least of a prevalent kind. Just
as it is standardly thought that the rational standing for our beliefs is no better than our envatted
counterpart, and hence non-factive, so it is widely held that the rational basis for our beliefs, even
in the very best epistemic conditions, is compatible with those beliefs being mostly false. Much of
the appeal of (at least a certain kind of) radical scepticism follows from this point. If
epistemological disjunctivism is true, however, then we can block this rationale for radical
scepticism at its source, as in epistemically good conditions the rational standing of our beliefs is
clearly very different indeed from our envatted counterparts, and certainly not compatible with the
widespread falsity of our beliefs. Epistemological disjunctivism is thus uniquely placed to account
for how our reasons can genuinely hook-up with the world, rather than being rational standings
that could be completely disconnected to how the world actually is.24
How does the kind of knowledge described by epistemological disjunctivism square with
anti-risk virtue epistemology? Let’s start with the anti-risk element of the view. If one’s basis for
belief is a factive reason, then the safety condition is straightforwardly met, as clearly one cannot
form a belief on that same basis in close possible worlds and yet believe falsely.25 In particular,
there cannot be a high risk of error from forming a belief on this basis, as there is no risk at all.
This shouldn’t surprise us, given that one needs to be in epistemic conditions that are both
objectively and subjectively good in order to enjoy the factive reason in play.
Moreover, notice that the safety of the subject’s belief, based on the reflectively accessible
factive reason, is also significantly attributable to her manifestation of relevant cognitive agency.
This follows from the nature of the epistemic conditions in which the factive reason in question is
reflectively available. Recall that the objectively good epistemic conditions that need to obtain
involve one’s cognitive faculties functioning appropriately in an environment for which they are
suited, while the subjectively good epistemic conditions that need to obtain ensure that the subject
is appropriately forming her belief on the basis of the reflectively accessible factive reason. It is the
former condition which ensures that the subject sees that p. But for this to be reflectively available
to the subject as a reason for belief, it is important that the latter condition also holds.26 It is the
combination of these objective and subjective epistemic conditions that ensures that the safety of
the subject’s belief is significantly attributable to her manifestation of relevant cognitive agency.
The objectively good epistemic conditions entail that one’s cognitive agency is a significant factor
in enabling one to see that p in the first place, and the subjectively good epistemic conditions entail
that one is appropriately basing one’s belief on this reflectively accessible factive reason (which
guarantees the safety of one’s belief). It follows that it is not just one’s cognitive success that is
13
significantly attributable to one’s cognitive agency, but also one’s safe cognitive success.
Indeed, it is arguably the case that when it comes to factive reflectively accessible reasons
of the kind that epistemological disjunctivism describes a subject’s safe cognitive success will be
primarily attributable to that subject’s cognitive agency. Given the epistemically paradigm nature of
the cognitive conditions in which the belief is formed, it is hard to see how other factors could
prevent the subject’s cognitive agency from playing an overarching explanatory role in her safe
cognitive success. In particular, it seems natural to treat the subject’s cognitive agency as being
primarily responsible for her safe cognitive success, where this is enabled by the optimal cognitive
conditions that the subject is operating in. In any case, all that is necessary for our purposes is that
epistemological disjunctivism satisfies the weaker explanatory requirement laid down by anti-risk
virtue epistemology.
Of course, that epistemological disjunctivism is compatible with anti-risk virtue
epistemology doesn’t explain why one should find this pairing of views desirable. There is an
important rationale in this respect, however, and it concerns what role reflectively accessible
reasons can play within a moderate epistemic externalism about knowledge. As we have noted,
what is significant about epistemological disjunctivism is that it rejects an orthodox conception of
rational support such that one’s reasons always fall short of the world, in the sense that they are
compatible with widespread falsity in one’s beliefs. We can see the relevance of this point to
moderate epistemic externalism about knowledge by considering what such an orthodox
conception of reasons would contribute to anti-risk virtue epistemology. The satisfaction of safe
cognitive responsibility would ensure that one’s cognitive agency is appropriately hooked-up with
the world. Having, in addition, reflectively accessible non-factive reasons would then be the ‘icing
on the cake’, in that it would enable one to provide a rational story in support of one’s beliefs. But
notice that such reasons are not themselves anchored in the world at all, due to their non-factive
nature, as they are compatible with one’s beliefs being massively false. Accordingly, on an
orthodox conception of epistemic internalism the satisfaction of an internalist epistemic condition
in addition to meeting the anti-risk virtue epistemology rubric thus merely supplies rational
support that, as it were, runs parallel to, but is also importantly disconnected from, the safe
cognitive responsibility that relates one’s beliefs to the world.
In contrast, combining epistemological disjunctivism with anti-risk virtue epistemology
leads to a very different kind of proposal. The rational support that one’s beliefs enjoy in
epistemically paradigm cases of perception is now such that it offers the agent a rational grip on
the ways things are in the world, and not merely the kind of cognitively skillful grip on the world
represented by safe cognitive responsibility. This is important to preserving the desirability of
having reflectively accessible reasons, since if our primary manifestation of cognitive responsibility
14
is in terms of a skillful responsiveness to the world that is independent of those reasons, then they
start to look like mere baubles—nice to have, but serving no deep epistemic purpose. In contrast,
by incorporating epistemological disjunctivism into anti-risk virtue epistemology, we can capture a
way in which a rational grasp of the world can be manifested from within an externalist account of
knowledge.
One concern that one might have about incorporating epistemological disjunctivism
within anti-risk virtue epistemology is that factive reasons must impose high cognitive demands on
the subject, due to their decisive nature. If that’s right, then wouldn’t that saddle this putatively
‘moderate’ epistemic externalism about knowledge with an onerous intellectualism regarding
certain core kinds of knowledge?
We noted earlier that questions about the strength of the cognitive responsibility
condition—such as whether it demands safe or only veritic cognitive responsibility, or whether the
explanatory relation should be cast in stronger or weaker terms¾are independent of epistemic
internalism, in that on any of these construals one could nonetheless fail to satisfy an internalist
epistemic condition. Going in the other direction, it is also true that the strength of the epistemic
internalist support that one’s belief enjoys can come apart from the extent of cognitive agency on
display. In particular, a reflectively accessible factive reasons is the strongest kind of internalist
epistemic support available, but it doesn’t follow that in possessing such a reason one exhibits a
superlative level of cognitive agency.27
Indeed, the factive reasons at issue in epistemological disjunctivism are a good case in
point in this regard, in that even if they do suffice to ensure that one’s safe cognitive success is
primarily attributable to one’s cognitive agency, this wouldn’t be because one has made any great
cognitive efforts. In particular, according to epistemological disjunctivism, factive reflectively
accessible reasons are not one’s reward for exceptional intellectual efforts, but rather occupy a
kind of default status in the space of reasons, at least as regards our perceptual engagement with
the world.28 It is in virtue of being inculcated into a social fabric of reasons, whereby one cultivates
an appropriate sensitivity to relevant abnormal epistemic conditions, that one thereby acquires the
practice of presenting factive supporting reasons in epistemically paradigmatic conditions.
Epistemological disjunctivism is distinctive in taking this practice at face-value, in opposition to
epistemological orthodoxy on this score. In any case, with factive reasons so understood, it is clear
why their decisive epistemic status does not require intellectual feats on the part of the subject.
The reality is in fact the opposite: factive reasons come easily (at least to subjects suitably
embedded in the relevant social practice), it is rather the non-factive reasons that tend to impose
higher intellectual demands. That is, it is appropriately responding to departures from epistemically
paradigmatic conditions that imposes the higher intellectual burden on agents. Incorporating
15
epistemological disjunctivism into the heart of anti-risk virtue epistemology thus doesn’t pose any
danger of leading to an onerous intellectualism about certain core kinds of knowledge.29
5. CONCLUDING REMARKS
Let’s try to put together the pieces that we have assembled. The picture that emerges is of a
general conception of knowledge—anti-risk virtue epistemology—that demands safe cognitive
responsibility. This proposal is a form of epistemic externalism, but it can nonetheless
accommodate the internalist insight that knowledge demands cognitive responsibility. It is also
compatible with epistemic internalism as being generally applicable to the knowledge possessed by
cognitively developed agents. We thus have a moderate epistemic externalism about knowledge.
Then there is epistemological disjunctivism, which we have seen is not only consistent
with anti-risk virtue epistemology but when combined with it can capture the sense in which a
specifically rational grip on the world can be core to our epistemic standing. Accordingly, by
integrating epistemological disjunctivism within anti-risk virtue epistemology we are able to offer a
moderate externalist account of knowledge that doesn’t merely capture an externalist skill-like
conception of cognitive responsibility where reflectively accessible reasons, where possessed, run
in parallel to one’s knowledge. Instead, we are in a position to explain how the knowledge
possessed by cognitively developed agents can fundamentally involve a rational grip on the world
that functions in concert with a more general skillful cognitive responsibility.30

NOTES
This is an accessibilist construal of the internalist epistemic condition, of a kind defended by Chisholm (1977) and
Bonjour (1985, ch. 2), amongst others. This is in contrast to the mentalist account of epistemic internalism¾offered by,
for example, Conee & Feldman (2004)¾ such that what matters in this regard are the mental states of the subject.
Nonetheless, I don’t think anything important is lost by focusing on accessibilism in this regard. Mentalists usually
grant, after all, that the subject’s mental states that are relevant to the epistemic standing of her beliefs are reflectively
accessible; their point is just we are interested in such reflective access because we are interested in the mental states
being accessed, rather than vice versa. Finally, notice that this account of an internalist epistemic condition requires that
the subject has reflectively accessible reasons in support of the truth of the target proposition, and not merely in
support of her believing it, such as might be supplied by the kind of entitlement strategy advocated by Wright (e.g.,
2004) for at least certain kinds of beliefs (in ‘cornerstone’ propositions). For our purposes, we can set aside how best
to locate such proposals within the epistemic externalism/internalism debate.
2 At least, this is the standard post-Gettier narrative that gets told (e.g., in contemporary epistemology textbooks). As
it happens, I’m inclined to think that the historical situation is much more complex, at least to the extent that insofar
as commentators pre-Gettier endorsed anything akin to a theory of knowledge, then it’s at least arguable that they
were understanding the epistemic condition in an importantly different way to how Gettier (1963) describes it. For
some relevant historical discussion of the ‘classical’ theory of knowledge, see Dutant (2015) and Le Morvan (2017).
3 For the classical defence of process reliabilism, see Goldman (1979; 1986). For a recent defence of the view, see
Olsson (2012; 2015).
4 In Pritchard (2005a; 2005b) I call this variety of epistemic luck reflective epistemic luck.
5 For a key defence of virtue reliabilism (albeit referred to ‘agent reliabilism’), see Greco (1999; 2000). For some other
proposals that are in the vicinity of virtue reliabilism (albeit not usually described in these terms), see Sosa (1991; 2007;
2009; 2011; 2015; 2021), Goldman (1992), and Plantinga (1993b).
6 See, especially, Pritchard (2020). See also Pritchard (2016b; 2017a). As will become clear in a moment, anti-risk
virtue epistemology is a variant of anti-luck virtue epistemology, which I have defended in earlier work, such as Pritchard,
Millar & Haddock (2010, ch. 3) and Pritchard (2012a; 2017b).
7 For some key defences of versions of the safety principle for knowledge, see Sainsbury (1997), Sosa (1999), and
Williamson (2000, passim). Note that below I apply the general idea behind safety to successful outcomes in general,
rather than just to cognitive successes (i.e., true beliefs, for our purposes).
8 See Pritchard (2005a; 2007; 2012c; 2015a).
9 Indeed, more than this, anti-luck (/anti-risk) epistemology offers us a rationale for understanding the safety
principle in a particular way, one that avoids the problems that have been raised against it (e.g., regarding how it
accommodates knowledge of necessary truths). It would take us too far afield to get into these issues here, however.
For further discussion in this regard, see Pritchard (2005a; 2007; 2012c; 2015a).
10 For further defence of anti-risk epistemology, and why it is an advance on anti-luck epistemology, see Pritchard
(2016b; 2017a; 2020). For more on the modal accounts of luck and risk that underlie both anti-risk and anti-luck
epistemology, see Pritchard (2014; 2015c).
11 Inevitably the necessity of safety for knowledge—and the anti-luck/risk intuition that underlies it—has its
detractors too. See, for example, Bauman (2012), and Hetherington (2013). See also endnote 20.
12 This distinction is essentially the same as the distinction between intervening and environmental luck (and their
specifically epistemic variants) that I have drawn in earlier work, but with the focus placed instead on the closely
related notion of risk. See, especially, Pritchard (2009a; 2012a) and Pritchard, Millar & Haddock (2010, chs. 2-4).
13 For a more precise way of putting this point, see the epistemic twin earth argument discussed in Kallestrup &
Pritchard (2014) and Pritchard (2016a), which is explicitly designed to capture what is at issue in cases of
environmental risk (/luck).
14 This example is, of course, from Chisholm (1977, 105).
15 The barn façade case is originally due to Goldman (1976), who credits it in turn to Carl Ginet.
16 This has been contested, of course¾see endnote 20.
17 This is a variation on the ‘Temp’ case that I offer in, for example, Pritchard (2012a).
18 For a recent defence of anti-risk virtue epistemology, see Pritchard (2020). See also the defence of anti-luck virtue
epistemology offered in Pritchard (2017b).
19 I discuss robust virtue epistemology in a number of places. See especially Pritchard (2009b; 2012a) and Pritchard,
Millar & Haddock (2010, chs. 2-4). For some key defenses of (forms of) robust virtue epistemology, see Sosa (1991;
2007; 2009; 2011; 2015; 2021), Zagzebski (1996; 1999), and Greco (2009).
20 For a further refinement of this objection against robust virtue epistemology, see the epistemic twin earth argument
offered in Kallestrup & Pritchard (2014) and Pritchard (2016a). Note that some proponents of robust virtue
epistemology, such as Sosa (e.g., 2007, ch. 5), bite this bullet and argue that barn façade cases show that there can be
lucky knowledge. This is not without obvious costs, as explained in Pritchard (e.g., 2009a). Moreover, once we express
the point specifically in terms of epistemic risk, then the costs are higher still, as one now needs to contend that
knowledge is compatible with high levels of epistemic risk. For more on this point, see Pritchard (2016b; 2020).

For further discussion of this critique of robust virtue epistemology, see Pritchard (2009b; 2012a; 2016b), Pritchard,
Millar & Haddock (2010, chs. 2-4), and Kallestrup & Pritchard (2014).
22 Epistemological disjunctivism is rooted in the work of McDowell (e.g., 1995), but the presentation of it here is
entirely my own. I develop this proposal in a number of places—see especially Pritchard (2012b). See also Neta &
Pritchard (2007) and Pritchard (2008).
23 This is the so-called new evil demon intuition. See Lehrer & Cohen (1983) and Cohen (1984). For discussion, see
Littlejohn (2009).
24 For a development of this anti-sceptical line, see Pritchard (2015b, part 3; 2018; cf. Pritchard 2012b, part 3).
25 There are some complex issues raised by the basing relation as it applies to epistemological disjunctivism, though it
would take us too far afield to explore them here. For discussion, see Pritchard (2019b).
26 This point explains why epistemological disjunctivism rejects the thesis that seeing that p entails knowing that p, as
defended, for example, by Dretske (1969), Williamson (2000), and Cassam (2007). This is because the former can
obtain without the latter thereby obtaining (though in such cases it won’t be available to the subject as a reflectively
accessible reason). See Pritchard (2011; 2012b, part 1) for more on this point.
27 At least, it is the strongest kind of internalist epistemic support available insofar as one restricts one’s attention to
fallibilist internalist epistemic support (i.e., epistemic support that is acquired via a fallible cognitive process). The
factive epistemic support that is at issue in epistemological disjunctivism is derived via the fallible cognitive process of
perception, after all (which is why it is important to keep factivity of epistemic support apart from questions of
infallibility). Of course, there might not be any infallible cognitive processes, especially regarding one’s epistemic
access to facts about an external world, but if there are and they issue internalist epistemic support, then of course
they would generate factive rational support of an even more impressive epistemic pedigree.
28 It is an open question whether factive reasons could be extended to other domains. McDowell (e.g., 1994) clearly
thinks that they do, though I do not take a stand on this issue here. It will be enough for our purposes that they apply
in the perceptual domain.
29 For further discussion of the relationship between epistemological disjunctivism and anti-risk virtue epistemology
(at least where the latter is under the guise of anti-luck virtue epistemology), see Pritchard (2019a).
