As is well known, Michael Huemer (2001, 2006, 2007) has put forward an internalist2 version of epistemic justification, which he calls “Phenomenal Conservatism” (for short ‘PC’), whose principle is:
(PC) If it seems to S as if P, then S has at least prima facie justification for believing that P. (2001, p. 99)
In a revised formulation, addressing criticisms made by Michael Tooley (cf. Huemer 2007, p. 30, note 1) that seemings or appearances3 can sometimes be “weak” and “wavering”, Huemer’s principle now claims:
(PC-rev) If it seems to S that p, then, in the absence of defeaters, S thereby has at least some degree of justification for believing that p.4 (2007, p. 30, italics added)
Whether in the original formulation or in its revised form, the principle clearly affirms (or implies) that an appearance that P can be sufficient for prima facie justification (or justification simpliciter, in the absence of defeaters).5 Presumably, if the appearance is clear and strong enough, it is sufficient for justification (in the absence of defeaters). Huemer thinks that this principle governs the epistemological status not only of non-inferential (or basic, or foundational) beliefs, as it was originally thought by him, but also of inferential ones (see his 2007 for the new understanding). We should also note that some authors, like Michael Bergmann (2013, pp. 154-5 note 4), have pointed out that for Huemer appearances are not only sufficient but also necessary for justification, as one can infer from various passages of Huemer’s work (although that is not inferred from the above principles themselves). In any case, our attention in this paper will be on the foregoing principles, as they state a sufficient condition for epistemic justification.6
One can be wondering, of course, about what exactly appearances are. Although there are many criticisms of this notion of Huemer’s (see, for example, Tooley 2013, pp. 309-18), that will not be our concern here. For our purposes we can concede that appearances are - in Huemer’s words - “a kind of propositional attitude, different from belief, of which sensory experience, apparent memory, intuition, and apparent introspective awareness are species” (2007, p. 30). We can also concede that they are “assertive mental representations”, in the sense that they “represent their content as actualized”, and that this constitutes their “forcefulness” (Huemer 2001, pp. 53-4, 66; cf. Tooley op. cit., p. 309). In this paper, moreover, we will assume, for the sake of simplicity, that in general appearances are sufficiently strong and clear (unless stated otherwise), so that it will not matter if we refer to (PC) instead of (PC-rev), not considering, therefore, “degrees” of justification.
One important question, however, that we can raise - and which will be the focus of this paper - is about the justification of (PC). Put in a straightforward way, we can (and should) ask: what reasons are there for thinking that (PC) is true, that is, for thinking that appearances justify beliefs? That seems a very fair question, and corresponds - to use BonJour’s (1985, p. 9ff) vocabulary - to the demand for a “metajustification” (i.e., the justification of a principle of justification, by giving (good) reasons for thinking that the principle is true).7 In fact, the task of finding such a metajustification seems essential to any proposal of a purported principle of justification: to neglect this task, remarks BonJour, “is to leave one’s epistemological theory quite unsupported at a crucial point, thereby rendering it ungrounded and essentially arbitrary from an epistemic standpoint.” (1985, p. 10).
But how exactly can (or should) this demand for metajustification be fulfilled? As we will see more clearly below, the pursuit of a metajustification can take different directions, depending on the general conception or nature of epistemic justification we are working with and on who is supposed to satisfy the demand.8 More specifically, it can take the following directions. First, it can assume a truth-conducivity conception of epistemic justification and then understand that the demand is to be satisfied by the theory or, which is the same, by the epistemologist. Second, still assuming a truth-conducivity conception of epistemic justification, it can understand that the demand is to be satisfied by the epistemic subject, S, herself. Finally, it can abandon the truth-conducivity conception of justification and take up a deontological one - in this case, the epistemologist has to show that the subject, S, is “blameless” in following her own (S’s) appearances.9
Unfortunately, however, all of these directions seem to lead PC to a dead end, as we will see. In other words, the apparently fair and even essential demand for a metajustification of (PC) - what reasons are there for thinking that (PC) is true? - cannot be met by PC, at least in a satisfactory way. If we are right about that, it will remain the difficult question - briefly talked about in the conclusion - whether PC is the only one (or even the right one!) to be blamed for this failure. A full discussion of this issue, however, is beyond the scope of this paper.
1. A Truth-Conducivity Conception of Justification:
If we assume that epistemic justification (henceforth, just ‘justification’) must be truth-conducive - as many (if not most of) contemporary epistemologists do -, we will require that justification somehow have or establish a (reliable) connection to truth, even if fallible. Within an internalist framework, adopted by Huemer and BonJour, among others - according to which what justifies a person’s belief must be accessible to him or her10 -, that assumption will imply that ‘to be justified in believing a proposition’ will mean, roughly, - to use BonJour’s suitably broad characterization11 - that “there is good reason or basis for thinking that [the] belief [i.e., the proposition believed] […] is true”, or “likely to be true” (2004, pp. 349 and 358 note 21), or “at least approximately true” (BonJour and Sosa 2003, p. 5). So, on this interpretation, Phenomenal Conservatism can be taken as in fact claiming the following sufficient condition for justification (assuming S has no defeaters for believing that P):
(PC*) If it seems to S that P, then S has good reason or basis for thinking that P is true (or likely to be true).12
A demand for metajustification requires that (PC*) itself be justified, that is, that there be good reasons for thinking that (PC*) is true, or, more exactly, good reasons for thinking that an appearance or seeming (that P) is good reason or basis for thinking that the proposition (P) is true (or likely to be true). As we said before, that seems a fair (not to say “essential”) demand. After all, one should not accept (PC*) arbitrarily, without good reasons. But who exactly should satisfy this demand for metajustification?
1.1 Metajustification required of the Theory or Epistemologist:
We can consider that the demand for metajustification is to be satisfied by the epistemological theory or, which is the same, by the epistemologist. BonJour’s (2004) criticism of Phenomenal Conservatism (and of direct realism in general) as well as Huemer’s (2007) response to it consider the demand in this way. In the section where he addresses this issue, Huemer (2007, pp. 50ff) does not use the exact form of (PC), (PC-rev), or even (PC*). Instead, he considers two other formulations that, in any case, should be understood as other versions of the same principle defended by Phenomenal Conservatism, if justification is explicitly understood in a truth-conducive way (and the term ‘justified’ is replaced accordingly). We will call them ‘(PC**)’ and ‘(PC***)’:
(PC**) If a belief is based on an appearance, then it is likely to be true. (ibid., pp. 50-51)13
And, in a “general proposition”:
(PC***) Probably, most of the things that seem true to us are true. (ibid., pp. 52-53)
According to the present metajustificatory requirement, the epistemologist (i.e., Huemer) needs to give reasons for thinking that (PC**) and/or (PC***) are true. Let us start with (PC**). How can Huemer give reasons for (PC**)? More exactly, how can he give reasons for thinking that a belief based on an appearance is likely to be true? According to Huemer himself (ibid., p. 51-2), he cannot! In fact, he should not even try to do it! For Huemer, it would be contrary to the “foundational” role of an appearance “to supply reasons” for thinking that a belief based on it is true. In other words, if an appearance is a source of non-inferential justification, we should not “demand reasons” for a belief based on it! Such a demand would “beg the question” against the foundationalist, since it assumes that a foundational belief is not in fact foundational! Comparing his position (i.e., direct realism) to the rationalist’s, he says:
The direct realist takes perceptual beliefs to be foundationally justified, no less than the rationalist takes intuitive beliefs to be foundationally justified. The direct realist view is not that we first notice that we have a perceptual experience with a certain character, and then infer that the external world is a certain way. And just as it would beg the question to object that the rationalist has failed to supply reasons for our intuitive beliefs, it would beg the question to object that the direct realist has failed to supply reasons for our perceptual beliefs. (Ibid., p. 52; his italics)
Huemer’s response can obviously be questioned. His objection might be right if we required reasons of the believer or subject, S, whose belief based on an appearance is purportedly foundational. But since we are considering the reasons that the epistemologist has to give for thinking that a subject’s belief based on an appearance is likely to be true, the accusation of begging the question seems misplaced. (After all, the epistemologist is expected to give an account (and a good one!) of the justification of foundational beliefs as much as he is expected to give an account of the justification of inferential beliefs, isn’t he? And how could he/she do that but by “supplying reasons”?). It is important to note, on this issue, that at one point of his article Huemer (ibid., p. 51-2) starts to use the first person plural (“we notice”, “our perceptual beliefs”) when talking about the foundational beliefs (see quotation above). This is certainly misleading, since it conflates the roles of the epistemologist and of the epistemic subject, allowing the kind of objection Huemer gives. In any case, let us see the answer that Huemer gives for the other formulation, (PC***).
Huemer (ibid., p. 52-4) thinks that to provide reasons for thinking that the “general proposition” (PC***) is true does not appear to beg the question as before. How can he, then, as an epistemologist, give reasons for thinking that the proposition
(PC***) Probably, most of the things that seem true to us are true
is true?
First, the theorist (i.e., Huemer) has to choose the notion of probability that he will work with. He could work, for example, with a physical concept of probability, like frequency. In such a case, presumably, the theorist would have to show that there is a high proportion of cases where things that seemed true to us were in fact true. But that is an externalist notion of justification - points out Huemer! -, appealing to “factors external to our minds” (ibid., p. 52). And Huemer, as an internalist epistemologist who “reject[s] externalism”, thinks Phenomenal Conservatism, an internalist theory of justification, could not be itself justified by epistemic externalism! So, this option is not available for him, as he recognizes it!14
The most interesting option for Phenomenal Conservatism, according to Huemer, seems to be an adoption of a logical or epistemic notion of probability, where ‘probability’ now means the degree to which one’s total evidence supports a given proposition.15 For Huemer, adopting this epistemic notion means that “the metajustificatory demand, applied to a particular epistemological theory, amounts in essence to a demand to show that we are justified in believing that most beliefs that are justified according to the theory are true.” (ibid., p. 53; his italics). So, according to Huemer, he has to show that “we” - presumably Huemer and his readers - are justified in believing the proposition “Most of the things that seem true to us are true”. How can he show that we are justified in believing this proposition? For Huemer (ibid., pp. 53f), there is no other way but to rely on PC itself! After all, PC is a “comprehensive theory” of justification - it purports to cover all cases of justification, even of itself! In this way, the theorist - Huemer - simply has to show that the proposition “Most of the things that seem true to us are true” seems true to us!! As we should expect, for Huemer this general proposition does seem true - at least to him:
We might try to satisfy this demand from within the theory of justification in question. [...]. In the case of Phenomenal Conservatism, we might try to show that the proposition, "Most of the things that seem true to us are true," seems true to us, or is supported by things that seem true to us. Well, it certainly seems to me that most of the things that seem to me to be true are true. It seems to me that there is a table here, and that's true. It seems to me that 2 + 2 = 4, and that's true. It seems to me that I exist, and that's true. When I think about examples like this, it seems to me that my appearances are reliable - in short, that most of them are true. (ibid., p. 53; his italics)
The above “argument” is clearly a form of epistemic circularity (cf. Alston 1986; Bergmann 2006, chapter 7). It assumes (not explicitly) that appearances are a reliable source of justification in order to show that appearances are a reliable source of justification! In other words, the argument depends on X in order to show that X is reliable! (cf. Bergmann 2006, pp. 179ff). Even if Huemer (2007, pp. 53f) could be right about the fact that a comprehensive theory of justification cannot avoid applying the theory to itself, the circularity here does not seem “benign” - to use Bergmann’s (2006) term -, since it is in a context in which it clearly begs the question against the critic of PC!16 Huemer should not rely on appearances to establish, against the critic of PC, that appearances are reliable! Huemer’s “argument”, in fact, shows at most that PC is not incoherent with itself or self-defeating - what is a desirable thing, of course! -, avoiding the embarrassing situation of a theory that, according to its own criteria, should not be accepted!17
So, what do we have so far? In trying to satisfy what seems to be a very plausible demand - the justification of a principle of justification, that is, the justification of (PC) in (at least) one of its several versions -, Huemer (and we) at first assumed two things, besides internalism: (i) justification is truth-conducive (in the sense of BonJour’s “having good reason or basis for thinking that P is true or likely to be true”); and (ii) the task of metajustification is to be satisfied by the theory or epistemologist. Where did he arrive? In one case, he could not do the task because doing that - according to him - would beg the question against the foundationalist (that is, against himself!). In another, he could not do it because he would have to base his internalist principle on epistemic externalism! In the last attempt, he clearly falls in “malignant” epistemic circularity, begging the question against the critic of PC!
What would happen if the demand for metajustification were to be satisfied by the believer or subject herself? Let us now see.
1.2. Metajustification required of the Subject
In a reply to DePoe (2011), Huemer (2011) addresses again the demand for metajustification. This time, however, he considers the case where the demand is to be satisfied by the subject - a “PC version” of Norman, the clairvoyant (cf. BonJour 1985, pp. 41ff), whose faculty of clairvoyance, now, “works by producing appearances” (Huemer 2011, pp. 8ff). Norman has no idea about the reliability of his faculty, although it is in fact reliable: his beliefs based on his appearances are all true. The criticism against Huemer and PC is that Norman could not be justified in his beliefs, unless Norman had evidence (presumably, an argument) that his faculty is reliable. Norman lacks that. According to BonJour/DePoe’s criticism, from Norman’s perspective, his beliefs are all accidentally true!
The metajustificatory demand, therefore, takes here this form: the believer or subject, S, has to have evidence - an argument - that her appearance-producing faculty(ies) is (are) reliable, otherwise S’s beliefs are not justified by her appearances. What is Huemer’s response to this demand?18 For him, it is too demanding! “Ordinary people” have no argument for the reliability of sense perception, memory, etc., being “unable to provide any arguments” for these faculties (2011, p. 10). They have no “independent corroboration” for the beliefs produced by those faculties, accepting them “in the same unreflective way” as Norman does. So, ordinary people are in the same situation as Norman’s. If we impose on a subject such a demand, “then almost all beliefs held by almost everyone in history have been unjustified” (ibid.), what seems absurd. (Huemer does not use that word, but that is clearly suggested). In other words, this kind of metajustificatory demand should be abandoned. As for the problem of a belief’s being accidentally true from S’s perspective - explains Huemer -, we should only impose “a negative condition on justified belief: if S believes or has grounds for believing P is at best accidentally true, then S is not justified in believing P” (Huemer, 2013, p. 337; italics added; cf. Idem, 2011, p. 10-11).19
We could change, however, the form of the metajustificatory demand imposed on the subject. Instead of demanding from her an argument for the reliability of her appearance-producing faculty(ies), we could focus on particular appearances. We could require that for S to be justified in believing that P based on an appearance that P, S has to have good reason, evidence, etc., for believing that the appearance is somehow relevant (epistemically) to the truth of P. This can seem very plausible initially. However, we have now a big problem - and it is not Huemer’s fault!20 As we know from Fumerton (1995, p. 64) and Bergmann (2006, pp. 14ff), this kind of requirement boils down to the following form (put in terms of propositional justification):
(X) S is justified in believing that P only if (i) there is an X (e.g. an appearance) that is (epistemically) relevant to the truth of P and (ii) S is justified in believing that X is relevant to the truth of P.21
As is now clearer, this kind of requirement gives rise to an infinite regress that is quite bad, because it involves not only an infinite number of levels of justification, but also an infinite number of levels of justification “of ever-increasing complexity”, to quote Fumerton (1995, p. 64). After all, to be justified in believing that P (based on X, an appearance), S has to be justified in believing that X (an appearance) is relevant to the truth of P. But to be justified in believing that X is relevant to the truth of P, (i) there must be a Y (another appearance?) that is (epistemically) relevant to the truth of X is relevant to the truth of P and (ii) S must be justified in believing that Y is relevant to the truth of [X is relevant to the truth of P]. And so on. Of course, nobody deserves such a requirement! We should reject this demand as unachievable, at least for us, human beings.22
So, what do we have now? Assuming a truth-conducivity notion of justification as well as the understanding that the metajustificatory demand is now to be satisfied by the subject, Huemer and PC get either to the unacceptable conclusion that almost everyone in history has been unjustified in their beliefs because ordinary people simply lack an argument for the reliability of their appearance-producing faculties23 - which seems absurd, Huemer suggests -, or to the situation of an infinite regress of levels of justification of “ever-increasing complexity”, which is unachievable for human beings. Either way, we have the same negative result.
Perhaps, the metajustificatory demand might be satisfied if (and only if) we abandon the truth-conducivity notion of justification and take up a deontological one. That is what we will try to do.
2. A Deontological Conception of Justification and the Metajustification of PC:
If we give up the constraint that justification is a matter of having (objectively speaking) “good reason or basis for thinking that a belief is true”, in BonJour’s words, adopting instead a notion that justification is a matter of being blameless in our epistemic “duty” of achieving truth (cf. Plantinga 1993, pp. 11ff), PC might perhaps be more fortunate in satisfying the metajustificatory demand. In fact, although Huemer does not explicitly say that, his main arguments for PC (mentioned briefly below) could be understood as presupposing this deontological notion of justification (see BonJour 2004, p. 360, n. 23). In this way, the metajustificatory task now would be for the epistemologist to show that an epistemic subject, S, is not “guilty” or “blameworthy” when holding beliefs based on her appearances.24 To be more exact, the epistemologist - in our case, Huemer - would have to give reasons for holding this deontological version of (PC), which we can call ‘(PCd)’:
(PCd) If it seems to S that P, then, if S has no defeaters, S is not (epistemically) blameworthy in believing that P.
We will not discuss here Huemer’s “Self-Defeat Argument” (2007, pp. 39ff), which deserves a separate paper. In any case, it has received many criticisms (cf. DePoe, 2011; Hasan, 2013), and even some proponents of PC do not accept it (cf. Tucker 2013, p. 9). On the other hand, his “Internalist Intuition Argument” (see Huemer 2006, pp. 149ff) fits in very well here. Basically, Huemer defends PC by pointing out that, when two propositions P and Q “seem alike”, from S’s perspective, “in all epistemically relevant respects”, it would be “intuitively irrational” if S had different doxastic attitudes towards them (ibid.). It would even be “absurd” for S to report: ‘P and Q seem alike for me in all epistemically relevant respects, but I believe P and disbelieve Q.’. So, any epistemological theory (either externalist or even internalist) that claims or implies that appearances are not sufficient for justified belief and that the subject should (also) follow other criteria of justification would be liable to such bizarre cases, imposing on S such irrationality. (Any other criterion would be, by hypothesis, beyond S’s appearances, and so it would justify that kind of “absurd” report by S!). This seems to be a good argument, based on a clear “intuition”.
As we said above, this argument fits in very well with a demand for metajustification when we consider justification as a matter of not being blameworthy. In fact, when S follows her appearances - and appearances are all that she ultimately has, reminds us Huemer, including the appearances of defeaters -, it seems right to recognize that S is not epistemically blameworthy in her believing. She is doing her best - all that we should expect from her, epistemically speaking, she is fulfilling. (PCd), therefore, seems justified.25
Let us assume, for the sake of the argument, that this is all true. (PCd), the deontological version of PC, was shown to be true. Is the demand for metajustification satisfied for the sake of PC? A positive answer for this question may still be very controversial. If one sticks to the (previous) understanding that epistemic justification has to be truth-conducive, and not (merely) deontological, one will not see the demand as satisfied. That is BonJour’s complaint, which is worth quoting:
If there were in fact no way to discriminate among seemings with respect to whether they yield genuine reasons for thinking that the corresponding claims are true, then it would be plausible enough that a person who accepted beliefs on the basis of seemings generally would be epistemically blameless simply because that is the only epistemic alternative that would be open. As I have argued elsewhere, however, being epistemically blameless (or satisfying other similar deontological requirements) is not enough for genuine epistemic justification: the aim of epistemic justification is truth, and the connection between blamelessness and truth is far too tenuous. (2004, p. 360, n.23)
BonJour concludes: “That we have nothing better to rely on, even if this is (as I doubt) genuinely the case, does not show that the best we have is good enough.” (ibid., p. 360).
So, if BonJour’s verdict is correct - many epistemologists would certainly agree with his remarks -, then the deontological path is not a “genuine” one for metajustification. We have to come back!
Conclusion
Where did we arrive, then? What have we got from Huemer’s efforts for metajustification? Let us review our wanderings with Huemer.
Everything started with a seemingly plausible and fair demand for justification of a principle of justification - (PC) -, that is, a metajustification. After all, we should not accept any principle of justification, like (PC), arbitrarily. We followed Huemer in his attempts to show, for the sake of PC, that such a demand is satisfied. The choices or directions available for Huemer were to take up either a truth-conducivity conception of (epistemic) justification or a deontological one. Especially in the first alternative, he had further to choose between understanding that the demand was to be satisfied by the epistemologist and understanding that it was to be satisfied by the subject. All directions got to a dead end:
The truth-conducivity/epistemologist direction led Huemer either to, according to him, begging the question against the foundationalist (i.e., against himself), or to externalism (also against himself!), or to malignant epistemic circularity, begging the question against his critics. The truth-conducivity/subject direction led him either to the unacceptable conclusion that almost everyone in history has been unjustified in their beliefs because they lack arguments for the reliability of their appearance-producing faculties, or to the unachievable infinite regress of levels of justification of ever-increasing complexity, with the same negative result. Finally, the deontological direction led him to an apparent success that, unfortunately, is not recognized as genuine by many of Huemer’s peers.
What conclusion can we draw from all this? That PC was not able to satisfy the metajustificatory demand and should, therefore, be rejected? That would be a careless conclusion. Although we could question some of Huemer’s responses - especially those concerning the role of the epistemologist in the task of metajustification (see section 1.1) -, a careful reflection on these unsuccessful attempts of metajustification may reveal that the “failure” is not peculiar to PC (see especially section 1.2) and that the “problem” - i.e., the reason(s) for the failure - can be elsewhere, although it is not easy to locate it precisely. We will be brief in this conclusion. First of all, can the problem be in the truth-conducivity conception of justification, since the deontological conception provided (apparently) no obstacles to the metajustificatory demand? The fact that the deontological conception allows an “easy” metajustification is hardly a reason for thinking that the truth-conducivity conception is “the (or a) problem” and that the deontological conception is the right one, though. All that it shows is that the problem arises in connection with the truth-conducivity conception, whether this is or not the right conception of epistemic justification. Since many (if not most) epistemologists think the truth-conducivity conception is the right one, it seems important to identify the reasons for the failure to meet the metajustificatory demand when that conception is assumed. Can the problem, then, be in internalism as a whole, the requirement that what justifies a subject’s belief must be accessible to her? But externalism has also had a hard time trying to meet the metajustificatory demand. As Alston (1986; 1993; 2005, pp. 201ff) insisted repeatedly, the externalist cannot show the reliability of sense-perception without falling in epistemic circularity!26 How about foundationalism? Is it the problem? We can doubt it. The alternative to it - i.e., inferentialism, whether in its coherentist or infinitist version - does not seem to overcome skeptical results, as we glimpsed in section 1.2.27 Finally - as one may be suspecting -, perhaps the problem is in the metajustificatory demand itself! But what this charge implies? That we should not try to justify our epistemic principles? That those principles could and should be accepted without (good) reasons? This cannot be right!
Perhaps, the real problem is that the metajustificatory demand makes us reach the inevitable limits of our epistemic condition. But this deserves another paper.
