A Defense of Restricted Phenomenal Conservatism

Abstract

In this paper, I criticize Michael Huemer's phenomenal conservatism, the theory of justification according to which 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. Specifically, I argue that beliefs and hunches provide counterexamples to phenomenal conservatism. I then defend a version of restricted phenomenal conservatism, the view that some but not all appearances confer prima facie justification on their propositional contents. Specifically, I defend the view that S has defeasible justification for believing that p if and only if it seems to S that p and it seems to S that she is acquainted with the fact that makes p true. Finally, I criticize Huemer's self-defeat argument for phenomenal conservatism.     

Skeptical Conclusions

For a putative knower S and a proposition P, two types of skepticism can be distinguished, depending on the conclusions they draw: outer skepticism, which concludes that S does not know that P, and inner skepticism, which concludes that S does not know whether P. This paper begins by showing that outer skepticism has undesirable consequences because that S does not know that P presupposes P, and inner skepticism does not have this undesirable consequence since that S does not know whether P does not presuppose P. We indicate that the two types of skepticism aim to different loci of doubts: while outer skepticism doubts whether we can gain an epistemic warrant for the actuality, inner skepticism doubts whether we can gain epistemic identification of the actuality. It is further indicated that responses to skepticism from externalist theories, as well as from fallibilist internalist theories, can only respond to outer skepticism but not to inner skepticism.     

Gricean Communication and Transmission of Thoughts

Gricean communication is communication between utterers and their audiences, where the utterer means something and the audience understands what is meant. The weak transmission idea is that, whenever such communication takes place, there is something which is transmitted from utterer to audience; the strong transmission idea adds that what is transmitted is nothing else than what is communicated. We try to salvage these ideas from a seemingly forceful attack by Wayne Davis. Davis attaches too much significance to the surface structure of sentences of the type ‘S communicates the belief (desire …) that p to A’ by assuming that the communicated entity is denoted by the grammatical object following ‘communicates’. On our proposal, what is communicated in all Gricean cases is a thought. And since S communicates the thought that p to A only if S means that p and A understands what S means, the thought that p will be transmitted from S to A.     

Knowledge despite falsehood

I examine the claim, made by some authors, that we sometimes acquire knowledge from falsehood. I focus on two representative cases in which a subject S infers a proposition q from a false proposition p. If S knows that q, I argue, S's false belief that p is not essential to S's cognition. S's knowledge is instead due to S's belief that p′, a proposition in the neighbourhood of p that S (dispositionally) believes (and knows). S thus knows despite her false belief. The widely accepted and plausible principle that inferential knowledge requires known premises is unscathed.     

The duplication of love's reasons

If X loves Y does it follow that X has reasons to love a physiologically exact replacement for Y? Can love's reasons be duplicated? One response to the problem is to suggest that X lacks reasons for loving such a duplicate because the reason-conferring properties of Y cannot be fully duplicated. But a concern, played upon by Derek Parfit, is that this response may result from a failure to take account of the psychological pressures of an actual duplication scenario. In the face of the actual loss of a loved one and the subsequent appearance of a duplicate, how could we resist the inclination to love? Drawing upon duplication scenarios from Parfit and from Stanislaw Lem's Solaris, this paper will argue that there could be reasons for X to come to love a duplicate of Y but that these would not be identical with the reasons that X had (and may still have) to love Y. Nor (in the case of an agent with a normal causal history) could they be reasons for a love that violates the requirement that love is a response to a relationship and therefore takes time to emerge.     

Is Every Theory of Knowledge False?

Is knowledge consistent with literally any credence in the relevant proposition, including credence 0? Of course not. But is credence 0 the only credence in p that entails that you don't know that p? Knowledge entails belief (most epistemologists think), and it's impossible to believe that p while having credence 0 in p. Is it true that, for every value of ‘x,’ if it's impossible to know that p while having credence x in p, this is simply because it's impossible to believe that p while having credence x in p? If so, is it possible to believe that p while having (say) credence 0.4 in p? These questions aren't standard epistemological fare—at least in part because many epistemologists think their answers are obvious—but they have unanticipated consequences for epistemology. Let ‘improbabilism’ name the thesis that it's possible to know that p while having a credence in p below 0.5. Improbabilism will strike many epistemologists as absurd, but careful reflection on these questions reveals that, if improbabilism is false, then all of the most plausible theories of knowledge are also false. Or so I shall argue in this paper. Since improbabilism is widely rejected by epistemologists (at least implicitly), this paper reveals a tension between all of the most plausible theories of knowledge and a widespread assumption in epistemology.     

STRONG INTERIORITY AND (TRADITIONAL) THEISM: WHAT'S THE PROBLEM?

Central to Spinozism is the thesis that the immanence of the Divine Substance in the cosmos (in natural objects) is – like the immanence of the dancer in the dance –maximal or total. Just as the dance consists entirely of the dancer in aesthetically‐stylized motion, so the domain of nature is nothing in addition to God in cosmic guise. Accordingly, natural objects constitute modes of God. Hence, Spinozism and (traditional) theism are obviously irreconcilable. For it is indispensable to theism that the immanence of God in the cosmos is not maximal; rather, that natural objects are distinct from the Divine Substance. Now it has standardly been presupposed by theists (and many others) that natural objects could not be distinct from God without being ontologically exterior to God; thus, that theism would readily collapse into Spinozism if the cosmos was interior to the Divine Substance. It seems to me that this is a long‐standing mistake. After demonstrating that there is probative warrant for maintaining that theism requires the interiority of natural objects to God, there is shown to be more than adequate justification for denying that this necessitates the collapse of theism into Spinozism.     

Heidegger and the Essence of Dasein

Being and Time argues that we, as Dasein, are defined not by what we are, but by our way of existing, our “existentiell possibilities.” I diagnose and respond to an interpretive dilemma that arises from Heidegger's ambiguous use of this latter term. Most readings stress its specific sense, holding that Dasein has no general essence and is instead determined by some historically contingent way of understanding itself and the meaning of being at large. But this fails to explain the sense in which Being and Time is a work of fundamental ontology, concluding in Heidegger's claim to have found the meaning of Dasein's being in the concept of originary temporality. On the other hand, readings that stress the general sense of “existentiell possibilities” find Heidegger on a fruitless quest for the transcendental conditions necessary for Dasein's existence, which seems to founder on the claims that Dasein is constitutively thrown, factical, and “in‐each‐case‐mine” [jemeinig]. Both readings are problematic and, I contend, result from a failure to disambiguate and explain the ontologically unique relationship between the specific and general aspects of Dasein's essence. I argue that we can better explain this relationship, Heidegger's method for investigating it, and the sense in which Dasein has an essence that is open to philosophical investigation, if we read Being and Time's ontology of Dasein in terms of what Anton Ford calls “categorial” genus‐species relationships.     

On the alleged normative significance of a platitude

It seems to be a platitude that the belief that p is correct iff it is true that p. And the claim that truth is the correct‐making feature of belief seems to be just another way of expressing this platitude. It is often thought that this indicates that truth constitutes a normative standard or criterion of correctness for belief because it seems to follow from this platitude that having a false belief is believing wrongly, and having a true belief is believing rightly or correctly. In this paper, I aim to show that when we judge the platitude in question to be indisputably true, we do not endorse that truth is normative for belief but merely the triviality that the belief that p is true iff it is true that p.     

Value Incomparability and Indeterminacy

Two competing accounts of value incomparability have been put forward in the recent literature. According to the standard account, developed most famously by Joseph Raz, ‘incomparability’ means determinate failure of the three classic value relations (better than, worse than, and equally good): two value-bearers are incomparable with respect to a value V if and only if (i) it is false that x is better than y with respect to V, (ii) it is false that x is worse than y with respect to V and (iii) it is false that x and y are equally good with respect to V. Most philosophers have followed Raz in adopting this account of incomparability. Recently, however, John Broome has advocated an alternative view, on which value incomparability is explained in terms of vagueness or indeterminacy. In this paper I aim to further Broome’s view in two ways. Firstly, I want to supply independent reasons for thinking that the phenomenon of value incomparability is indeed a matter of the indeterminacy inherent in our comparative predicates. Secondly, I attempt to defend Broome’s account by warding off several objections that worry him, due mainly to Erik Carlson and Ruth Chang.     

Split identity: intransitive judgments of the identity of objects

Identity is a transitive relation, according to all standard accounts. Necessarily, if x = y and y = z, then x = z. However, people sometimes say that two objects, x and z, are the same as a third, y, even when x and z have different properties (thus, x = y and y = z, but x ≠ z). In the present experiments, participants read stories about an iceberg that breaks into two icebergs, one to the east and the other to the west. Many participants (32–54%, in baseline conditions across experiments) decided that both successors were the original iceberg, despite the different spatial locations of the successors. Experiment 1 shows that this tendency is not due to participants failing to understand both to mean both are simultaneously the original. Similarly, Experiment 2 demonstrates that the tendency is not solely due to their interpreting the question to be about properties of the icebergs rather than about the icebergs themselves. Experiments 3 and 4 suggest, instead, that participants may understand Which is the original? to mean Which, in its own right, is entitled to be the original? Emphasizing entitlement increases the number of seemingly intransitive responses, whereas emphasizing the formal properties of identity decreases them.     

Practical Certainty

When we engage in practical deliberation, we sometimes engage in careful probabilistic reasoning. At other times, we simply make flat out assumptions about how the world is or will be. A question thus arises: when, if ever, is it rationally permissible to engage in the latter, less sophisticated kind of practical deliberation? Recently, a number of authors have argued that the answer concerns whether one knows that p. Others have argued that the answer concerns whether one is justified in believing that one knows that p. Against both of these, this paper argues that the answer concerns whether p is ‘practically certain’—that is, whether the actual epistemic probability that p differs from epistemic certainty that p only in ways that are irrelevant to the decision one currently faces.     

Omniscience and worthiness of worship

At first glance, the properties being omniscient and being worthy of worship might appear to be perfectly co-instantiable. (To say that some properties are co-instantiable is just to say that it is possible that some object instantiate all of them simultaneously. Being entirely red and being a ball are co-instantiable; being entirely red and being entirely blue are not). But there are reasons to be worried about this co-instantiability, as it turns out that, depending on our commitments with respect to certain kinds of knowledge and notions of personhood, it might be the case that no being—God included—could instantiate both. In this paper, I lay out and motivate this claim before going on to consider a variety of responses—some more plausible than others—that may be offered by the theist.     

Memory conjunction clusters: Influence of familiarity and recollection

In the memory conjunction paradigm, the number of times that constituents of conjunction lures were studied and the method of presentation were varied. In two experiments, participants were presented with eight parent items that could be recombined at test to form a conjunction lure. The constituents that were shared between the parent items and the conjunction lures were either presented in the same words (e.g., blackmail and jailbird presented four times each for the conjunction lure blackbird) or in different words (e.g., the targets footstool, footlocker, foothill, footbridge, baseball, softball, basketball, and golfball for the conjunction lure football). In both experiments, rates of false recognition were higher in the Different condition as opposed to the Same condition. These results provide evidence that participants in the Same condition were able to utilise a recall-to-reject strategy by remembering the repeatedly presented parent word. In the Different condition, participants were not able to utilise that strategy and instead relied on the familiarity of the repeatedly presented constituents which led to higher rates of false recognition.     

Beyond inference by eye: Statistical and graphing practices in JEAB, 1992‐2017

Debates about the utility of p values and correct ways to analyze data have inspired new guidelines on statistical inference by the American Psychological Association (APA) and changes in the way results are reported in other scientific journals, but their impact on the Journal of the Experimental Analysis of Behavior (JEAB) has not previously been evaluated. A content analysis of empirical articles published in JEAB between 1992 and 2017 investigated whether statistical and graphing practices changed during that time period. The likelihood that a JEAB article reported a null hypothesis significance test, included a confidence interval, or depicted at least one figure with error bars has increased over time. Features of graphs in JEAB, including the proportion depicting single‐subject data, have not changed systematically during the same period. Statistics and graphing trends in JEAB largely paralleled those in mainstream psychology journals, but there was no evidence that changes to APA style had any direct impact on JEAB. In the future, the onus will continue to be on authors, reviewers and editors to ensure that statistical and graphing practices in JEAB continue to evolve without interfering with characteristics that set the journal apart from other scientific journals.     

Against Fallibilism

In this paper I argue for a doctrine I call ‘infallibilism’, which I stipulate to mean that If S knows that p, then the epistemic probability of p for S is 1. Some fallibilists will claim that this doctrine should be rejected because it leads to scepticism. Though it's not obvious that infallibilism does lead to scepticism, I argue that we should be willing to accept it even if it does. Infallibilism should be preferred because it has greater explanatory power than fallibilism. In particular, I argue that an infallibilist can easily explain why assertions of ‘p, but possibly not-p’ (where the ‘possibly’ is read as referring to epistemic possibility) is infelicitous in terms of the knowledge rule of assertion. But a fallibilist cannot. Furthermore, an infallibilist can explain the infelicity of utterances of ‘p, but I don't know that p’ and ‘p might be true, but I'm not willing to say that for all I know, p is true’, and why when a speaker thinks p is epistemically possible for her, she will agree (if asked) that for all she knows, p is true. The simplest explanation of these facts entails infallibilism. Fallibilists have tried and failed to explain the infelicity of ‘p, but I don't know that p’, but have not even attempted to explain the last two facts. I close by considering two facts that seem to pose a problem for infallibilism, and argue that they don't.     

Aristotle on the reducibility of all valid syllogistic moods to the two universal moods of the first figure (APr A7, 29b1–25)

In Prior Analytics A7 Aristotle points out that all valid syllogistic moods of the second and third figures as well as the two particular moods of the first figure can be reduced to the two universal first-figure moods Barbara and Celarent. As far as the third figure is concerned, it is argued that Aristotle does not want to say, as the transmitted text suggests, that only those two valid moods of this figure whose premisses are both universal statements are directly reducible to Barbara and Celarent, but rather that it is those four valid moods of this figure whose respective minor premisses are universal statements of which this is true. It is shown that in order to carry this sense the transmitted text has to be corrected by inserting just one word, which seems to have dropped out.     

Possible knowledge of unknown truth

Fitch’s argument purports to show that for any unknown truth, p, there is an unknowable truth, namely, that p is true and unknown; for a contradiction follows from the assumption that it is possible to know that p is true and unknown. In earlier work I argued that there is a sense in which it is possible to know that p is true and unknown, from a counterfactual perspective; that is, there can be possible, non-actual knowledge, of the actual situation, that in that situation, p is true and unknown. Here I further elaborate that claim and respond to objections by Williamson, who argued that there cannot be non-trivial knowledge of this kind. I give conditions which suffice for such non-trivial counterfactual knowledge.     

Patterns of Aggression in Parents and their Children

In this research, we examined children's awareness of inconsistencies in messages that are meaningful for children, instructions for games. In the first experiment, kindergarten (n = 25) and second- (n = 25) and fourth-grade (n = 26) children were individually read the instructions for two games, each of which included two inconsistent statements. Chi-square analyses yielded a significant effect for grade for one game (p < .05) and a marginally significant effect for a second game (p < .10). In a second experiment, second- (n = 40), fourth- (n = 40), and sixth-grade (n = 40) children were read the instructions for two games, each of which included two statements that were inconsistent. An analysis of variance demonstrated that with an increase in grade, there was a significant increase (p < .001) in awareness that a message contained an inconsistency. The analysis also indicated that the subjects were more willing (p < .08) to question an adult than they were to question a child about an inconsistency. Moreover, a regression analysis indicated that awareness of inconsistencies in the rules for games was significantly related to memory (p < .001) and to one's ability to note inconsistencies in shorter, simpler messages (p < .001).
