According to some philosophers who accept a propositional conception of evidence, someone's evidence includes a proposition only if it is true. I argue against this thesis by appealing to the possibility of knowledge from falsehood.

If evidence is propositional, is one’s evidence limited to true propositions or might false propositions constitute evidence? In this paper, I consider three recent attempts to show that there can be ‘false evidence,’ and argue that each of these attempts fails. The evidence for the thesis that evidence consists of truths is much stronger than the evidence offered in support of the theoretical assumptions that people have relied on to argue against (...) this thesis. While I shall not defend the view that evidence is propositional, I shall defend the view that any propositional evidence must be true. (shrink)

False beliefs and misleading evidence have striking similarities. In many regards, they are both epistemically bad or undesirable. Yet, some epistemologists think that, while one’s evidence is normative (i.e., one’s available evidence affects the doxastic states one is epistemically permitted or required to have), one’s false beliefs cannot be evidence and cannot be normative. They have offered various motivations for treating false beliefs differently from true misleading beliefs, and holding that only the (...) latter may be evidence. I argue that this is puzzling: If misleading evidence and false beliefs share so many important similarities, why treat them differently? I also argue that, given the striking similarities between false beliefs and misleading evidence, many arguments for the factivity of evidence overgeneralize. That is, if these arguments were conclusive, they would also entail that the evidence cannot be misleading. But this is an overgeneralization, since the evidence can be misleading. (shrink)

This chapter analyzes the relation between brain sciences and philosophy of mind, in order to clarify in what ways philosophy can contribute to neuroscience and neuroscience can contribute to philosophy. Especially since the 1980s and the emergence of “neurophilosophy”, more and more philosophers have been bringing home morals from neuroscience to settle philosophical issues. I mention examples from the problem of consciousness, philosophy of perception and the problem of free will, and I argue that such attempts are not successful in (...) trying to settle questions like whether psychology can be reduced to neuroscience, whether we see the external world directly in perception, or whether we have free will. The failure results from an ability of the philosophical questions to evade the data. What makes these questions persisting philosophical questions is precisely that there is no way to settle them through empirical evidence, as they are conceptual questions and their solution lies in conceptual analysis.

Wordly internalists claim that while internal duplicates always share the same evidence, our evidence includes non-trivial propositions about our environment. It follows that some evidence is false. Worldly internalism is thought to provide a more satisfying answer to scepticism than classical internalist views that deny that these propositions about our environment might belong to our evidence and to provide a generally more attractive account of rationality and reasons for belief. We argue that worldly internalism (...) faces serious difficulties and that its apparent advantages are illusory. First, it cannot adequately handle some not terribly strange cases of perceptual error. Second, it cannot explain why one should plan to use their evidence to update their beliefs. The second issue allows us to explain why cases of misplaced certainty do not require us to introduce false evidence into our views and that why the alleged advantage of worldly internalism in resisting sceptical pressures is illusory.

The paper aims to show that, if S5 is the logic of metaphysical necessity, then no state of affairs in any possible world constitutes any non-trivial evidence for or against the existence of the traditional God. There might well be states of affairs in some worlds describing extraordinary goods and extraordinary evils, but it is false that these states of affairs constitute any (non-trivial) evidence for or against the existence of God. The epistemological and metaphysical consequences (...) for philosophical theology of assuming that S4 or Kσρ is the logic of metaphysical necessity are equally untenable. S4 guarantees that God does not exist if there is the slightest evidence against the existence of God. And Kσρ guarantees that God might survive the loss or acquisition of any essential property at all. (shrink)

According to the standard analysis, quantifiers such as , connectives such as , modals such as and a host of other expressions form informational scales (Horn, 1972). In the canonical case, informational scales are defined on the basis of entailment (e.g. p and q asymmetrically entails p or q). Given the Gricean assumption that speakers try to say as much as they truthfully can that is relevant to the conversational exchange, the fact that an informationally weaker term was used in (...) (1)-(3) often gives the listener reason to think that the speaker was not in a position to offer a stronger statement (presumably because such a statement would be false). Thus, even though weak scalar expressions such as some and or have a lower-bounded semantics (for instance some means ‘some and possibly all’), their semantic content is typically upper-bounded by a conversational implicature (e.g. ‘some but not all’). More recently, the precise mechanisms responsible for the computation of scalar implicatures (SIs) have become the topic of much debate. There is considerable disagreement as to whether SIs are derived on the basis of broadly Gricean quantity considerations, as the traditional account would have it, or post- Gricean relevance-oriented computations, whether they are the result of local or global calculations, and whether they are context-specific or generalized, default inferences (for varying perspectives, see Hirschberg, 1985; Sperber and Wilson, 1986/1995; Grice, 1989; Carston, 1990, 1998; Horn, 1992; Levinson, 2000; Chierchia, 2001). In several cases, SIs have been used to motivate and illustrate very different views of the architecture of the semantics-pragmatics interface. Despite their prominent place in the theoretical linguistic literature, scalar inferences have attracted relatively little attention in psycholinguistics.. (shrink)

ABSTRACTAccording to the Dogmatism Puzzle presented by Gilbert Harman, knowledge induces dogmatism because, if one knows that p, one knows that any evidence against p is misleading and therefore one can ignore it when gaining the evidence in the future. I try to offer a new solution to the puzzle by explaining why the principle is false that evidence known to be misleading can be ignored. I argue that knowing that some evidence is misleading (...) doesn't always damage the credential of the evidence, and therefore it doesn't always entitle one to ignore it. I also explain in what kind of cases and to what degree such knowledge allows one to ignore evidence. Hopefully, through the discussion, we can not only understand better where the dogmatism puzzle goes wrong, but also understand better in what sense rational believers should rely on their evidence and when they can ignore it.

Epistemic contextualism is the thesis that the standards that must be met by a knowledge claimant vary with contexts of utterance. Thus construed, EC may concern only knowledge claims, or else the knowledge relation itself. Herein, my concern is with “Substantive EC.” Let’s call the claim that the sorts of linguistic evidence commonly cited in support of Semantic EC also imply or support Substantive EC the “Implication Thesis”. IP is a view about which some epistemologists have equivocated. Keith (...) DeRose is a case in point. Herein I argue that IP is false, and that it is false for interesting reasons. To this end, I consider two other terms which DeRose investigates, “free will” and “potency” in his efforts to demonstrate the alleged inability of distinctly philosophical or skeptical doubts to infect ordinary epistemic discourse. I describe how and why these two examples speak against, rather than for, DeRose’s recommendation of Substantive EC. (shrink)

Revised simulation theory allows mental state attributions containing some or all of the attributor's genuine, non-simulated mental states. It is thought that this gives the revised theory an empirical advantage, because unlike theory theory and rationality theory, it can explain egocentric bias. I challenge this view, arguing that theory theory and rationality theory can explain egocentricity by appealing to heuristic mindreading and the diagnosticity of attributors' own beliefs, and that these explanations are as simple and consistent as those provided (...) by revised simulation theory. (shrink)

Does rationality require imprecise credences? Many hold that it does: imprecise evidence requires correspondingly imprecise credences. I argue that this is false. The imprecise view faces the same arbitrariness worries that were meant to motivate it in the first place. It faces these worries because it incorporates a certain idealization. But doing away with this idealization effectively collapses the imprecise view into a particular kind of precise view. On this alternative, our attitudes should reflect a kind of normative (...) uncertainty: uncertainty about what to believe. This view refutes the claim that precise credences are inappropriately informative or committal. Some argue that indeterminate evidential support requires imprecise credences; but I argue that indeterminate evidential support instead places indeterminate requirements on credences, and is compatible with the claim that rational credences may always be precise.

It is commonly thought that we depend fundamentally on the “evidence of the senses” for our empicial beliefs, including and most directly, our beliefs about our local environment, the spatial world around us. The ultimate evidence we have for our perceptual beliefs is provided in some way by perception or perceptual experience. But what is this evidence? There seem to be three main options: external factualism allows that the evidence include facts about the external world; (...) internal factualism takes facts that involve only the internal, mental world—like facts about one’s perceptual experiences or appearances—to count as one’s perceptual evidence; and non-factualism takes propositions, including false ones, to count as evidence—for example, propositional contents of appearances or seemings. We shall see that all these options face significant challenges. Some might conclude that perceptual beliefs can be justified without depending on evidence. Others might choose to accept skepticism: our perceptual beliefs are not justified. I shall end, however, by tentatively suggesting that there is a sort of internal fact that is a plausible candidate for perceptual evidence that has been overlooked. (shrink)

I distinguish between two claims of transparency of experiences. One claim is weaker and supported by phenomenological evidence. This I call the transparency datum. Introspection of standard perceptual experiences as well as bodily sensations is consistent with, indeed supported by, the transparency datum. I formulate a stronger transparency thesis that is entailed by representationalism about experiential phenomenology. I point out some empirical consequences of strong transparency in the context of representationalism. I argue that pain experiences, as well as (...) some other similar experiences like itches, tickles, orgasms, hedonic valence, etc., are not transparent in this strong sense. Hence they constitute empirical counterexamples to representationalism. Given that representationalism is a general metaphysical doctrine about all experiential phenomenology for good reasons, I conclude that representationalism about phenomenal consciousness is false. Then, I outline a general framework about how the introspection of phenomenal qualities in perceptual experience works in light of the transparency datum, but consistent with the rejection of strong transparency. The result is a form of qualia realism that is naturalist and intentionalist, and has close affinities to the adverbialist views developed in the latter part of the last century. I then apply this framework to pain experiences and their bodily locations. (shrink)

Beginning with Zagzebski (The Philosophical Quarterly 44:65–73, 1994), some philosophers have argued that there can be no solution to the Gettier counterexamples within the framework of a fallibilist theory of knowledge. If true, this would be devastating, since it is believed on good grounds that infallibilism leads to scepticism. But I argue here that these purported proofs are mistaken and that the truthmaker solution to the Gettier problems is both cogent and fallibilist in nature. To show this I develop (...) the notion of evidence of a state of affairs, a crucial concept in the truthmaker theory. I also argue that a common principle of the transmission of evidence through entailment is false, and the cause of much of the trouble. (shrink)

There is a growing body of empirical evidence which shows that infants and non-human primates have the ability to represent the mental states of other agents, i.e. that they possess a Theory of Mind. We will argue that this evidence also suggests that infants and non-human primates possess the concept of truth, which, as we will explain, is good news for primitivists about truth. First, we will offer a brief overview of alethic primitivism, focusing on Jamin Asay’s conceptual (...) version of the view. Next, we will survey relevant work on Theory of Mind which indicates that children younger than two and non-human primates are able to attribute false beliefs. Then, we will bring these false-belief data to bear on Asay’s form of primitivism, arguing that the data support two of the four distinctive theses of this view and offering some remarks about the empirical evaluability of the two remaining theses. We hope that our discussion will help to bridge the gap between psychological and philosophical inquiry and that it will encourage further empirical research on the cognitive significance of the concept of truth for humans and other thinking creatures.

Among other interesting proposals, Juan Comesaña’s _Being Rational and Being Right_ makes a challenging case that one’s evidence can include falsehoods. I explore some ways in which we might have to rethink the roles that evidence can play in inquiry if we accept this claim. It turns out that Comesaña’s position lends itself to the conclusion that while false evidence is possible and not even terribly uncommon, I can be rationally sure that I don’t currently (...) have any and perhaps also that I won’t get any, and (absent certain evidence to the contrary) you are not afflicted with any either. This conclusion might seem too good to be true. I finish by raising a puzzle about one of the main motivations for Comesaña’s view. (shrink)

Some opponents of abortion claim that fetuses are persons from the moment of conception. Following Berg (2017), let us call these individuals “Personhood-At-Conception” (or PAC), opponents of abortion. Berg argues that if fetuses are persons from the moment of conception, then miscarriage kills far more people than abortion. As such, PAC opponents of abortion face the following dilemma: They must “immediately” and “substantially” shift their attention, resources, etc., toward preventing miscarriage or they must admit that they do not actually (...) believe that fetuses are persons from the moment of conception (or, at least, they must recognize that they are not acting in ways that are consistent with this belief). In this essay, I show that Berg’s argument fails at each step. Specifically, after outlining her argument (in section 1), I consider the central claim of Berg’s style of argument: That “miscarriage…is much deadlier than abortion.” In section 2, I argue that this claim is false (when taken literally) and misleading otherwise. In section 3, I show that Berg’s style of argument is identical in structure to a criticism that is sometimes levied against the recent “Black Lives Matter” movement. In the latter context, the argument has been vehemently rejected. I argue that Berg’s style of argument should be rejected for the same reasons. Finally, in section 4, I show that Berg’s suggestion that opponents of abortion should divert “substantial” amounts of money and attention to miscarriage prevention faces two problems. First, these claims are made without any evidence regarding the actual priorities and spending habits of PAC opponents of abortion. If we are told “not enough is being done,” one wonders: What is being done and how much counts as “enough”? Berg gives no answer to either question. Second, even if it is true that opponents of abortion do not pay substantial attention to miscarriage prevention, Berg fails to notice that this may be for good reason. I conclude that PAC opponents of abortion do not face the dilemma that Berg presents. (shrink)

In general, the false cause fallacy occurs when the “link between premises and conclusion depends on some imagined causal connection that probably does not exist”. There are three different ways an argument can commit the false cause fallacy: post hoc ergo propter hoc; cum hoc ergo propter hoc; and ignoring common cause. This chapter focuses on one of the common fallacies in Western philosophy, 'ignoring common cause'. The commercial exploited the false cause fallacy to get consumers (...) to buy its product. This fallacy is also present in many of the arguments concerning the alleged connection between vaccines and autism despite the plethora of evidence otherwise. The chapter consists of various examples showcasing the fallacy of ignoring common cause. It also compares the examples, showing that slight changes can lead the other types of false cause fallacies to occur. (shrink)

There is quite some ethical controversy on Evidence-based Medicine (EbM) with regard to issues of physician autonomy as well as its allocative implications. Yet, there are some shortcomings in the current debate. First of all, some of the arguments brought up against EbM are similarly defaults of “classical medicine” as well, for instance its negligence of social aspects of medicine. Second, it is often maintained that EbM is just a tool to attain cost containment. This argument (...) is false in two regards for neither is there any idea of cutting costs in the roots of EbM nor does EbM once practiced necessarily lead to less costs as there can be underuse as well as overuse. Third, both opponents and proponents of EbM come up with the same arguments against each other. Both maintain that the other way of practicing medicine does not allow for physicians’ autonomy and free judgment. Therefore, we are going to search for the different presuppositions on which these “reproaches” rely. In this way we can demonstrate that both opponents and proponents rely on different notions of autonomy and free judgment in their argument. Finally, we hope to show that some of the ethical criticism may be raised against classical medicine as well and that allocation in terms of costs is not primarily an aim of EbM. (shrink)

There have been several attempts of late to read Yogācāra through the lens of Western phenomenology. I approach the issue through a reading of the Cheng weishi lun, a seventh-century Chinese compilation that preserves the voices of multiple Indian commentators on Vasubandhu’s Triṃśikāvijñaptikārikā. Specifically, I focus on the “five omnipresent mental factors” and the “four aspects” of cognition. These two topics seem ripe, at least on the surface, for phenomenological analysis, particularly as the latter topic includes a discussion of “self-awareness”. (...) Yet we find that the Cheng weishi lun account has little in common with the tradition associated with Husserl and his heirs. The categories and modes of analysis in the Cheng weishi lun do not emerge from or aver to a systematic reflection on the nature of “lived experience” so much as they are focused on subliminal processes and metaphysical entities that belong to the domain of the noumenal. In my conclusion I suggest that the later pramāṇa tradition associated with Dignāga and Dharmakīrti—a tradition that profoundly influenced later Yogācāra exegesis in Tibet—did indeed take a “phenomenological turn.” But my comparison shows that both traditions falter when it comes to relating conceptual content to non-conceptual experience, and thus there is reason to be skeptical about claims that phenomenology is epistemologically grounded in how the world presents itself first-personally.

The main question addressed in this paper is whether some false sentences can constitute evidence for the truth of other propositions. In this paper it is argued that there are good reasons to suspect that at least some false propositions can constitute evidence for the truth of certain other contingent propositions. The paper also introduces a novel condition concerning propositions that constitute evidence that explains a ubiquitous evidential practice and it contains a defense (...) of a particular condition concerning the possession of evidence. The core position adopted here then is that false propositions that are approximately true reports of measurements can constitute evidence for the truth of other propositions. So, it will be argued that evidence is only quasi-factive in this very specific sense. (shrink)

The present paper examines the concept of the meaning of life in the Soren Kierkegaard’s view. Kierkegaard sees the concept of "meaning" as "end" and believes in "biology" as the supreme biologist. Based on evidence from his works, he believes that the end is not to be discovered in biology, but it is creatable. There are three witnesses to this: first, the end is, in Kierkegaard''''''''s view, paradoxical, and paradox is not real, but mental. Secondly, Christianity, in his opinion, (...) is anxious, not religious, and religion is unreasonable, and in relation to the mind not connected with the outside, and third, that he does not consider God as an active being, but rather the existence of anxiety, The mind and mind of man. Kierkegaard''''''''s predictions in this evidence include ontological non-reality, individualism, and faith. An analysis of these three presumptions suggests that Kierkegaard believed in the supposition of meaning in life. (shrink)

In a paper published in Psychological Review, Tyler Burge has offered a unified non-mentalistic account of a wide range of social cognitive developmental findings. His proposal is that far from attributing mental states, young children attribute to humans the same kind of internal generic states of sensory registration that biologists attribute to e.g. snails and ticks. Burge’s proposal deserves close attention: it is especially challenging because it departs from both the mentalistic and all the non-mentalistic accounts of the data so (...) far. Moreover Burge has been one of the leading philosophers of mind of the past 40 years and some of his writings on the objectivity of perception display a deep understanding of the relevance of science for sharpening our understanding of the mind. After taking a close look at the developmental evidence, in particular at false-belief studies, I argue that Burge’s, 409–434, 2018) account faces severe obstacles. To give one telling example: if young children can only attribute to others sensory registrations, then it is hard to explain the evidence showing that they respond differently to an agent’s ignorance and to her false belief.

This chapter investigates the conflict between thought and speech that is inherent in lying. This is the conflict of saying what you think is false. The chapter shows how stubbornly saying what you think is false resists analysis. In traditional analyses of lying, saying what you think is false is analyzed in terms of saying something and believing that it is false. But standard cases of unconscious or divided belief challenge these analyses. Classic puzzles about belief (...) from Gottlob Frege and Saul Kripke show that suggested amendments involving assent instead of belief do not fare better. I argue that attempts to save these analyses by appeal to guises or Fregean modes of presentation will also run into trouble. I then consider alternative approaches to untruthfulness that focus on (a) expectations for one’s act of saying/asserting and (b) the intentions involved in one’s act of saying/asserting. Here I introduce two new kinds of case, which I call “truth serum” and “liar serum” cases. Consideration of these cases reveals structural problems with intention- and expectation-based approaches as well. Taken together, the string of cases presented suggests that saying what you think is false, or being untruthful, is no less difficult and interesting a subject for analysis than lying itself. Tackling the question of what it is to say what you think is false illuminates ways in which the study of lying is intertwined with fundamental issues in the nature of intentional action. (shrink)

Is science in the midst of a crisis of replicability and false discoveries? In a recent article, Alexander Bird offers an explanation for the apparent lack of replicability in the biomedical sciences. Bird argues that the surprise at the failure to replicate biomedical research is a result of the fallacy of neglecting the base rate. The base-rate fallacy arises in situations in which one ignores the base rate—or prior probability—of an event when assessing the probability of this event in (...) the light of some observed evidence. By extension, the replication crisis would result from ignoring the low prior probability of biomedical hypotheses. In this paper, my response to Bird’s claim is twofold. First, I show that the argument according to which the replication crisis is due to the low prior of biomedical hypotheses is incomplete. Second, I claim that a simple base-rate fallacy model does not account for some important methodological insights that have emerged in discussions of the replication crisis. (shrink)

A typescript by Claude Shannon, ‘Theorems on statistical sequences’, is examined to shed light on the development of information theory. In particular, it appears that Shannon was still working out the mathematical details of his theory in the spring of 1948, just before he published ‘A mathematical theory of communication’. This is contrasted with evidence from a declassified cryptography report that Shannon’s theory was intuitively worked out in its essentials by the time he filed the report in 1945. Previous (...) interviews with Shannon, and a recent interview with a colleague of his, Brockway McMillan, confirm this picture.Keywords: History of science; History of technology; Claude Shannon; Information theory; Ergodic theory; Electrical engineering.

This paper offers a new argument that your reasons for believing or acting need not be true. It proceeds indirectly through an account of what it takes to be happy that p. To be happy that p is for p to be among your reasons for being happy. That’s because questions about why you’re happy and what you’re happy is the case are interchangeable. But, I argue, it is possible to be happy that p even when p is false. (...) In cases in which you believe falsely that p and sincerely assert that you are happy that p, you are still expressing happiness about something. To be happy about something is to be happy that some proposition is the case. In the cases in question, it is implausible that the proposition you are happy is the case is a proposition about the evidence or how things seem or what you believe. The only other option is that the proposition you are happy is the case is p itself. Along the way, I discuss linguistic data that seems to counter the view that you can be happy that falsehoods are true. Though initially suggesting a more principled argument that you can only be happy about truths, both the linguistic data and the principled argument can ultimately be defused. A similar principled argument for the factivity of ‘knows,’ however, remains happily untouched. (shrink)

The phenomenon of fallacy is directly related to the nature of the person himself and the environment in which he lives. Knowing in which situations and how people are wrong will greatly prevent them from making Fallacies. For this reason, one of the most important aims of religions is to bring their followers to the happiness in this world and the hereafter, to determine the Fallacies that people may fall into beforehand and to reveal their reasons and solutions. The religions (...) of Judaism, Christianity and Islam are basically divinely based religions based on oneness (tawḥīd). However, Judaism and Christianity have been distorted for various reasons and have come out of the creed of oneness. One of the main reasons for their distancing from this primary source is that they make Fallacies on many issues, insist on this and do not take the necessary studies for a realistic solution. Because it is not possible to eliminate the fallacy without identifying the causes and finding solutions. The human being in communication and interaction with the beings around him establishes connections with them and makes decisions by reaching some conclusions. Disturbances in these connections, which are based on previous knowledge and experience, may cause fallacies in humans. Since the Tanakh and the Bible are sacred texts with distortion dimensions, the connections established with these sources may lead people to false beliefs on some issues instead of saving them from their Fallacies. The biggest mistake of the People of the Book, which is also the source of others, is that they see themselves not as servants of Allah but as their sons, adopted sons and especially friends. This situation led them to the distortions that they are exempt from certain orders and prohibitions and that they will be treated with privilege on the day of reckoning, or only they can enter the Paradise or they will stay in Hell for a limited number of days. Unfortunately, one of the reasons that lead them to think like this is the statements about themselves in the holy books they distorted. However, the Qurʾān has clearly revealed that their belief that they will be punished for a short time in Hell is a mistake and the truth is not as they claim. One of the most important issues of the Christian faith is the belief in the Trinity, which is the subject of constant debate both in the Christian world and in the Islamic world. Christians' excessive love for Jesus led them to the mistake of seeing Jesus as a divine being sent to save people from original sin, by not assuming him a human being. These thoughts of theirs were rejected in many verses of the Qurʾān and it is emphasized that Jesus is the servant and messenger of Allah. Another important mistake of the People of the Book is claiming that they were descended from Prophet Abraham and claiming the supremacy of lineage and therefore they did not accept the invitation of the Prophet Mohammed. In our study, we have discussed some basic distortions in the light of the Qurʾān, such as thinking that they are the beloved servants of Allah, ascribing deity to other than Allah, saying that Allah is not generous and that Paradise belongs to them what the people of the Book have fallen into while distorting their religion. From this point of view, first of all, we tried to determine the factors that affect Jews and Christians to fall into distortion that is to make wrong decisions that may result in disaster both worldly and otherworldly. Next, we examined how these factors, which we determined, affect the decision-making process and voluntary behaviors of people. Finally, we tried to determine the distortions that the Qurʾān deals with and the solutions it offers to eliminate these distortions in terms of the People of the Book. Although the Qurʾān and tafsīr (exegesis of the Qurʾān) sources constitute the main axis of our study, we also benefited from the sources of science such as psychology, sociology and morality. Unfortunately, it is seen that the People of the Book do not accept the distortion despite all the evidences, they still continue to feel superiority and choice both in terms of material and lineage, which leads them to distortions, and they act according to their old beliefs and behaviors. In addition, the fact that some Muslims in the past and today are led to these distortions is an indicator of how important the issue is. (shrink)

According to a received doctrine, espoused, by Karl Popper and Harry Collins, and taken for granted by many others, poorly replicated evidence should be epistemically defective and incapable of persuading scientists to accept the views it is used to argue for. But John Hughlings Jackson used poorly replicated clinical and post-mortem evidence to mount rationally compelling and influential arguments for a highly progressive theory of the organization of the brain and its functions. This paper sets out a number (...) of Jackson's arguments from his evidence and argues that they constitute a counter example against the received doctrine. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Gregory Currie TEXT WITHOUT CONTEXT: SOME ERRORS OF STANLEY FISH "Intuition told him that the vast ineptitude of the venture would serve as proof that no fraud was afoot." —Jorge Luis Borges, "Tom Castro, the Implausible Imposter," in A Universal History ofInfamy There are those of us who seek unity, universality, patterns of invariance in any diverse multitude of particulars. With the interpretation of texts, the diversity is (...) evident, the unity, universality and invariance less so. Still, we have the text itself, a sequence of determinately meaningful signs, independent of, and a constraint on, the activities of interpreters. We universalists might want more than that, but it's a start. It's a start some people are not prepared to give us. Stanley Fish is one of them. According to him we are looking for something which does not exist, and which we do not need. I shall argue that Fish is wrong on both counts. According to Stanley Fish, there are no constraints on interpretation that transcend particular, local interpretive communities. Indeed, there is no truth or validity that is community transcendent, no standard of lightness, proof or confirmation that has any warrant other than community approval. Intellectual ascendency is always ultimately a matter of rhetorical power, and the locus of power shifts as the norms of the community change. Yet we need not worry that this implies any dangerous kind ofrelativism or subjectivism. Each ofus is deeply immersed Philosophy and Literature, © 1991, 15: 212-228 Gregory Currie213 in his or her own community. Our thoughts, intentions, and actions gain their very identity from the structure of public, communitarian relations we enter into, and the community imposes on us a tight structure of norms and intellectual options that "situate" us (a favored word in the Fish vocabulary) in such a way that it is always clear what interpretive move is appropriate.1 Fish is no epistemological anarchist in the style of Feyerabend: it is not the case, for him, that "anything goes." There is always a clear distinction between what goes and what does not; it is just that the rules, the structure, the hierarchy of options are not invariant across time or communities.2 Now we do it like this, tomorrow we may do it like that; we do it this way, they do it that way. Wherever you are, the rules are always clear, but the rules depend on where you are. I shall call this thesis "internalism." It bears some resemblance to views of the later Wittgenstein, and rather closely parallels Thomas Kuhn's theory of scientific paradigms. It has a negative and a positive aspect. The negative aspect is that community-specific constraints on interpretation are all we have. The positive aspect is that they are all we need. Is internalism correct? I say it is not. I say that the positive claim is false, because internal constraints alone can never answer the relativist's challenge, when that challenge is properly understood; more about that in a moment. But this merely serves to highlight the importance of the negative thesis: if that is correct then relativism carries the day. So my primary concern here is with the negative thesis. Fish's main argument for the negative thesis is that what seems to most of us to be an obvious external constraint on interpretation—the literal meaning of the text in question—is no such thing. And he bases this claim on some arguments which purport to show that there L· no such thing as literal meaning. So my aim, it emerges at last, is to defend the idea of literal meaning. But first, I shall say something about the question of relativism. II Fish's answer to relativism, it will be remembered, is that interpretive communities constrain the interpretive choices of their members in such away that there can always be seen tobe nonarbitrary ways ofproceeding when it comes to formulating and choosing between interpretive hypotheses. This claim, the positive claim of Fish's internalism, raises two questions: Is Fish right, as a matter of fact, about the ways in which interpretive, and more generally intellectual communities constrain the 214Philosophy and Literature thoughts and actions...

The central question of the peer disagreement debate is: what should you believe about the disputed proposition if you have good reason to believe that an epistemic peer disagrees with you? This article shows that this question is ambiguous between evidential support (or propositional justification) and well-groundedness (or doxastic justification). The discussion focuses on conciliatory views, according to which peer disagreements require you to significantly revise your view or to suspend judgment. The article argues that for a wide range of (...) conceptions of evidential support, conciliatory views are false if they are understood entirely in terms of evidential support. Alternative conceptions of evidential support face some serious difficulties. These arguments speak against conciliationism, but the article then goes on to defend a conciliatory view about well-grounded belief: when you believe p, and you have good reason to believe that your epistemic peer disagrees with you, you are not justified in believing p because that belief is no longer well grounded. This picture of the epistemology of peer disagreement offers a reconciliation of some of the main competing views in the literature: conciliationism is true when we look at well-grounded belief, but a nonconciliatory view like Thomas Kelly's “total evidence view” is correct when we look at peer disagreement exclusively in terms of evidential support.

Findings from the cognitive sciences suggest that the cognitive mechanisms responsible for some memory errors are adaptive, bringing benefits to the organism. In this paper we argue that the same cognitive mechanisms also bring a suite of significant epistemic benefits, increasing the chance of an agent obtaining epistemic goods like true belief and knowledge. This result provides a significant challenge to the folk conception of memory beliefs that are false, according to which they are a sign of cognitive (...) frailty, indicating that a person is less reliable than others or their former self. Evidence of memory errors can undermine a person’s view of themselves as a competent epistemic agent, but we show that false memory beliefs can be the result of the ordinary operation of cognitive mechanisms found across the species, which bring substantial epistemic benefits. This challenge to the folk conception is not adequately captured by existing epistemological theories. However, it can be captured by the notion of epistemic innocence, which has previously been deployed to highlight how beliefs which have epistemic costs can also bring significant epistemic benefits. We therefore argue that the notion of epistemic innocence should be expanded so that it applies not just to beliefs but also to cognitive mechanisms. (shrink)

Satisfiability or Sat\ is the metatheoretic statementEvery formally intuitionistically consistent set of first-order sentences has a model.The models in question are the Tarskian relational structures familiar from standard first-order model theory, but here treated within intuitionistic metamathematics. We prove that both IZF, intuitionistic Zermelo–Fraenkel set theory, and HAS, second-order Heyting arithmetic, prove Sat\ to be false outright. Following the lead of Carter :75–95, 2008), we then generalize this result to some provably intermediate first-order logics, including the Rose logic. (...) These metatheorems distinguish the intuitionistic foundational significance of Sat\ sharply from that of Sat\, the satisfiability claim for intuitionistic propositional logic. At the same time, they establish intuitionistic connections with and between Test, COMP\, and \. Here, Test is the scheme of Testability, and COMP\ and \ are completeness for intuitionistic propositional logic and predicate logic, respectively. (shrink)

BackgroundSevere brain injury is a leading cause of death and disability. Diagnosis and prognostication are difficult, and errors occur often. Novel neuroimaging methods can improve diagnostic and prognostic accuracy, especially in patients with prolonged disorders of consciousness (PDoC). Yet it is currently unknown how family caregivers understand this information, raising ethical concerns that disclosure of neuroimaging results could result in therapeutic misconception or false hope.MethodsTo examine these ethical concerns, we conducted semi-structured interviews with caregivers of patients with PDoC who (...) were enrolled in a concurrent neuroimaging research program designed to detect covert consciousness following severe brain injury. Caregivers held surrogate decision-making status for a patient. Interviews were conducted at two time points for each caregiver. The first interview occurred before the disclosure of neuroimaging results. The second occurred after disclosure. Descriptive analysis was applied to the data of four interview topics: (1) expectations for neuroimaging; (2) reactions to evidence of preserved cognition; (3) reactions to null results; and (4) understanding of the results and study.ResultsTwelve caregivers participated in the study; two caregivers shared surrogate decision-making status for one patient with PDoC. Twenty-one interviews were completed; one caregiver declined to participate in the post-disclosure interview. Three patients with PDoC associated with the study displayed evidence of covert consciousness. Overall, caregivers understood the neuroimaging research and results. Caregivers who received results of covert consciousness were generally pleased. However, there was some variation in expectations and reactions to these data and null results.ConclusionThis study, for the first time, reveals caregiver expectations for and reactions to neuroimaging evidence of covert consciousness in patients with PDoC. Caregivers understood the neuroimaging research and results, casting doubt on speculative ethical concerns regarding therapeutic misconception and false hope. However, disclosure of neuroimaging result could be improved. Pre-disclosure consultations might assist professionals in shaping caregiver expectations. Standardization of disclosure might also improve comprehension of the results. (shrink)

The paper deals with certain issues with which Olivecrona was mainly concerned in his Philosophy of Law, notably (i) his views about the logical or syntactical form of imperatives as used in the law, and (ii) his views on the semantics of imperatives in the law and on the question whether and to what extent the notions of truth and falsity are applicable to those imperatives at all. In the light of an important critical notice of Olivecrona's work by Marc-Wogau (...) (1940 ), we examine some textual evidence for attributing to Olivecrona a so-called Atheoretical Thesis to the effect that imperatives in the law are neither true nor false or lack truth-value altogether. We close the paper by commenting on the celebrated distinction due to Hedenius (1941 ) and further elaborated by Wedberg (1951 ) between genuine ("rule-stating") normative sentences in the law and spurious ones (stating merely that a given rule is (or is not) in force in a given society at a given time). Two interesting difficulties bound up with that distinction will be dealt with. By means of various quotations we try to capture something of the flavour characterizing the legal philosophical discussion in Sweden in the mid-twentieth century during la belle époque of Scandinavian Legal Realism of which Olivecrona was a typical representative.

The Principle of Total Evidence is many things. We describe some of them.

Past life regression therapy is used by some physicians in cases with some mental diseases. Anxiety disorders, mood disorders, and gender dysphoria have all been treated using life regression therapy by some doctors on the assumption that they reflect problems in past lives. Although it is not supported by psychiatric associations, few medical associations have actually condemned it as unethical. In this article, I argue that past life regression therapy is unethical for two basic reasons. First, it (...) is not evidence-based. Past life regression is based on the reincarnation hypothesis, but this hypothesis is not supported by evidence, and in fact, it faces some insurmountable conceptual problems. If patients are not fully informed about these problems, they cannot provide an informed consent, and hence, the principle of autonomy is violated. Second, past life regression therapy has the great risk of implanting false memories in patients, and thus, causing significant harm. This is a violation of the principle of non-malfeasance, which is surely the most important principle in medical ethics. (shrink)

According to Allen Wood’s “procedural principle” we should believe only that which can be justified by evidence, and nothing more. He argues that holding beliefs which are not justified by evidence diminishes our self-respect and corrupts us, both individually and collectively. Wood’s normative and descriptive views as regards belief are of a piece with the received view which holds that beliefs aim at the truth. This view I refer to as the Truth-Tracking View (TTV). I first present a (...) modest version of TTV, one which is sensitive to standard criticisms and one which is fully consistent with the procedural principle. I then raise some doubts about TTV by considering both anecdotal cases and empirical studies. These studies suggest that certain types of belief are designed to aim away from truth, in limited, carefully calibrated ways. Moreover, it seems to be the case that selectively aiming away from the truth is important for human well-being and performance. Beliefs that are designed to aim away I dub “Tertullian” beliefs (t-beliefs). I then limn the distinguishing characteristics of t-belief and proceed to evaluate the procedural principle in light of the evidence which suggests that t-belief plays an important role in our cognitive economy. Next I argue that t-beliefs might be essential to the maintenance of self-respect and that they do not corrupt in the way that Wood claims. Finally, I argue that the fate of Wood’s procedural principle will be determined by the results of further empirical research— sociological, psychological, and neuroscientific. (shrink)

This paper’s main thesis is that in virtue of being believable, a believable novel makes an indirect transcendental argument telling us something about the real world of human psychology, action, and society. Three related objections are addressed. First, the Stroud-type objection would be that from believability, the only conclusion that could be licensed concerns how we must think or conceive of the real world. Second, Currie holds that such notions are probably false: the empirical evidence “is all against (...) this idea…that readers’ emotional responses track the real causal relations between things.” Third, responding with a full range of emotions to a novel surely requires that it be believable. Yet since we know the novel is fiction, we do not believe it. So in what does its believability consist? (shrink)

Arguments on legal evidence rely on generalizations, that link a certain circumstance to a certain hypothesis and warrants the claim that the circumstance makes the hypothesis more probable. Some generalizations are acceptable and others are unacceptable. A generalization can be unacceptable on at least four different grounds. A false generalization is unacceptable because membership in the reference class does not increase the probability of the hypothesis. A non-robust generalization is unacceptable because it uses a reference class that (...) is too heterogeneous. A biastriggering generalization is unacceptable because decision makers are inclined to overestimate the evidentiary value of membership in the reference class. A discriminating generalization is unacceptable because it puts members in the reference class in an unfair disadvantage. Research funded by the Swedish Research Council. (shrink)

Rationalist accounts of the development of folk-psychology maintain that the acquisition of this capacity is aided by special-purpose mechanisms rich in innate structure. Rationalists have typically maintained that false-belief understanding (FBU) emerges very early on, before the age of two. To explain why young children nonetheless fail the false-belief task, rationalists have suggested that they may have troubles expressing their FBU. Here I do two things. First, I argue that extant proposals about what might prevent children from expressing (...) their FBU cannot explain some of the relevant data. Second, I put forward a new rationalist proposal, the processing-time account, according to which young children fail because they cannot carry out all the required processing in the time available. I argue that the processing-time account overcomes the challenges extant rationalist accounts face while being compatible with the evidence in their support, thereby providing a compelling explanation of the development of FBU.

Consider the proposition, “Neither the motion of a body nor the action of a force affects space and time themselves”. We rejected this proposition when, in accepting the general theory of relativity, we accepted that the movement of a body or the action of a force affects the curvature of space-time. Compare the following proposition: “p and if and only if or ”. We think this is logically true; at least, most of us do. Some don’t, on empirical grounds—claiming (...) that we should interpret quantum mechanics as showing that the left-hand side can be true when the right-hand side is false. The idea is that the motions of bodies and actions of forces not only affect space-time relations, they also, as it were, affect logical relations as well. I think evidence from quantum mechanics—like empirical evidence generally—cannot possibly show that the equivalence fails to hold. I am convinced that I know a priori that p and if and only if or. My aim here is to explain the basis of this conviction. (shrink)

Eliminative induction is a method for finding the truth by using evidence to eliminate false competitors. It is often characterized as "induction by means of deduction"; the accumulating evidence eliminates false hypotheses by logically contradicting them, while the true hypothesis logically entails the evidence, or at least remains logically consistent with it. If enough evidence is available to eliminate all but the most implausible competitors of a hypothesis, then (and only then) will the hypothesis (...) become highly confirmed. I will argue that, with regard to the evaluation of hypotheses, Bayesian inductive inference is essentially a probabilistic form of induction by elimination. Bayesian induction is an extension of eliminativism to cases where, rather than contradict the evidence, false hypotheses imply that the evidence is very unlikely, much less likely than the evidence would be if some competing hypothesis were true. This is not, I think, how Bayesian induction is usually understood. The recent book by Howson and Urbach, for example, provides an excellent, comprehensive explanation and defense of the Bayesian approach; but this book scarcely remarks on Bayesian induction's eliminative nature. Nevertheless, the very essence of Bayesian induction is the refutation of false competitors of a true hypothesis, or so I will argue. (shrink)

It is well known that Bayes’ theorem (with likelihood ratios) can be used to calculate the impact of evidence, such as a ‘match’ of some feature of a person. Typically the feature of interest is the DNA profile, but the method applies in principle to any feature of a person or object, including not just DNA, fingerprints, or footprints, but also more basic features such as skin colour, height, hair colour or even name. Notwithstanding concerns about the extensiveness (...) of databases of such features, a serious challenge to the use of Bayes in such legal contexts is that its standard formulaic representations are not readily understandable to non-statisticians. Attempts to get round this problem usually involve representations based around some variation of an event tree. While this approach works well in explaining the most trivial instance of Bayes’ theorem (involving a single hypothesis and a single piece of evidence) it does not scale up to realistic situations. In particular, even with a single piece of match evidence, if we wish to incorporate the possibility that there are potential errors (both false positives and false negatives) introduced at any stage in the investigative process, matters become very complex. As a result we have observed expert witnesses (in different areas of speciality) routinely ignore the possibility of errors when presenting their evidence. To counter this, we produce what we believe is the first full probabilistic solution of the simple case of generic match evidence incorporating both classes of testing errors. Unfortunately, the resultant event tree solution is too complex for intuitive comprehension. And, crucially, the event tree also fails to represent the causal information that underpins the argument. In contrast, we also present a simple-to-construct graphical Bayesian Network (BN) solution that automatically performs the calculations and may also be intuitively simpler to understand. Although there have been multiple previous applications of BNs for analysing forensic evidence—including very detailed models for the DNA matching problem, these models have not widely penetrated the expert witness community. Nor have they addressed the basic generic match problem incorporating the two types of testing error. Hence we believe our basic BN solution provides an important mechanism for convincing experts—and eventually the legal community—that it is possible to rigorously analyse and communicate the full impact of match evidence on a case, in the presence of possible errors.

If non-human animals have high moral status, then we commit a grave moral error by eating them. Eating animals is thus morally risky, while many agree that it is morally permissible to not eat animals. According to some philosophers, then, non-animal ethicists should err on the side of caution and refrain from eating animals. I argue that this precautionary argument assumes a false dichotomy of dietary options: a diet that includes farm-raised animals or a diet that does not (...) include animals of any kind. There is a third dietary option, namely, a diet of plants and non-traditional animal protein, and there is evidence that such a diet results in the least amount of harm to animals. It follows therefore that moral uncertainty does not support the adoption of a vegetarian diet. (shrink)

An important question in the current debate on the epistemic significance of peer disagreement is whether evidence of evidence is evidence. Fitelson argues that, at least on some renderings of the thesis that evidence of evidence is evidence, there are cases where evidence of evidence is not evidence. I introduce a condition and show that under this condition evidence of evidence is evidence.

This paper proposes an account of why proof is the only way to acquire knowledge of some mathematical proposition’s truth. Admittedly, non-deductive arguments for mathematical propositions can be strong and play important roles in mathematics. But this paper proposes a necessary condition for knowledge that can be satisfied by putative proofs (and proof sketches), as well as by non-deductive arguments in science, but not by non-deductive arguments from mathematical evidence. The necessary condition concerns whether we can justly expect (...) that if the mathematical proposition is actually false, despite the evidence for its truth, then this fact has an explanation.
