I defend the acceptance principle for testimony (APT), that hearers are justified in accepting testimony unless they have positive evidence against its reliability, against Elizabeth Fricker's local reductionist view. Local reductionism, the doctrine that hearers need evidence that a particular piece of testimony is reliable if they are to be justified in believing it, must on pain of scepticism be complemented by a principle that grants default justification to some testimony; I argue that (APT) is the principle required. I consider (...) two alternative weaker principles as complements to local reductionism; one yields counter-intuitive results unless we accept (APT) as well, while the other is too weak to enable local reductionism to avoid scepticism.

The knowledge account of assertion holds that it is improper to assert that p unless the speaker knows that p. This paper argues against the knowledge account of assertion; there is no general norm that the speaker must know what she asserts. I argue that there are cases in which it can be entirely proper to assert something that you do not know. In addition, it is possible to explain the cases that motivate the knowledge account by postulating a general (...) norm that assertions would be true, combined with conversational norms that govern all speech acts. A theory on which proper assertions must be true explains the data better than a theory on which proper assertions must be known to be true. (shrink)

I argue against unqualified acceptance of the principle of deductive closure (DC): that, if p follows deductively from premises that are already known, we are in a position to know p. DC, I claim, is a sorites premise; it seems intuitively irresistible, but indiscriminate application of it leads to absurd conclusions. Furthermore, a theory on which the application of DC is restricted explains our practice of deriving new knowledge from old knowledge better than a theory on which our application of (...) DC is unrestricted. This restriction on the application of DC allows contextualists to meet an argument of Hawthorne’s that contextualism must lead either to absurd knowledge attributions or to constant shifting of the standards for knowledge. Even if the standard of knowledge remains constant, the absurd knowledge attribution is the conclusion of a sorites argument and should be rejected. (shrink)

I argue for an alternative to invariantist, contextualist, and relativist semantics for ‘know’. This is that our use of ‘know’ is inconsistent; it is governed by several mutually inconsistent inference principles. Yet this inconsistency does not prevent us from assigning an effective content to most individual knowledge ascriptions, and it leads to trouble only in exceptional circumstances. Accordingly, we have no reason to abandon our inconsistent knowledge-talk.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.4 (2003) 369-372 [Access article in PDF] Unity of Agency and Volition:Some Personal Reflections Stephen Weiner The issues of unity of agency, self-as-narrative, and more generally, volition are highly personal to me. Indeed, I would say I have frequently been obsessed with them. I am 52 years old, and date the onset of my psychiatric symptoms—my long-term misery—very specifically: 11:00 pm Pacific Standard Time, (...) August 28, 1965. At almost precisely that time, I started obsessing that I was homosexual and, in fact, turning into a girl. Within days, derealization followed: for instance, the houses in my neighborhood seemed one-dimensional—they seemed as though they were painted, as though I could stick my hand or an object through them. Colors seemed less bright as well—but I hardly had words for all this at the time: it was an overwhelmingly preverbal feeling, but I found some words for it.I was also depressed, and knew I was depressed—that is, I was worried, had trouble sleeping, and had suicidal thoughts and feelings. Within weeks, I asked my parents if I could see a psychiatrist, and I did. I remember asking my psychiatrist if he ever thought about the possibility that everything might be an illusion, and he quoted the refrain from "Row, Row, Row Your Boat": "merrily, merrily, merrily, merrily, life is but a dream." But just asking him produced a chilling feeling that he did not exist and, largely for this reason, I did not mention unreality feelings again to therapists for another 20 years.So, like Dr. Wells' patient Edward, described by James Phillips (2003), I was in trouble; like Edward, I was starting to construct a narrative. I started feeling that I had "to tell my story" at about this time—before then, I had not felt a need to do that. That may be partly because young children take life for granted (at least, I did), and it may be partly because suffering, by its very nature, demands explanation; both reasons were probably operating—certainly, both my parents told me years later that I had seemed emotionally distressed as a child, and my mother told they would have given me Ritalin if it had been available. So, to other people (my parents and my teachers) I was mentally ill in some sense, and I have some pretty clear memories of what I now recognize as depression, especially in the second and third grades; but I did not think of myself as sick and I did not think of myself as suffering—and I did not experience the duality (at least) of selves that I started to experience almost immediately in August 1965.Phillips further points out that the "future Edward" could look back in his narrative, at a later age, and reconstruct his history either as someone with a continuing mental illness, or as someone who had attained a secure, healthy adulthood and saw his experience as adolescent pain in the service of ultimate adult health and integration. I see my story, I am sorry to report, as [End Page 369] one of unremitting basic pain but with the positive dimension that I was able to go on, obtain a good education, work a good deal in my adult life, and father a child. But my narrative—and am I not, as a highly verbal person, almost constrained to think of my life as a narrative?—has been one, as Phillips (following Kleinman) realizes, of suffering. It is, above all else, an illness narrative. I find the approach of J. Melvin Woody (2003)—of privileging performing and performing arts and spatial metaphors over story—less relevant and true to myself, although I see no reason to argue with Mary's preference for such forms. It may be that the temporal discontinuities she has experienced predispose her to see herself in such terms—may, in fact, necessitate doing so. I am not exactly sure why, but it probably has to do with acting, with trying on and performing one role... (shrink)

Suppose we consider knowledge to be valuable because of the role known propositions play in practical reasoning. This, I argue, does not provide a reason to think that knowledge is valuable in itself. Rather, it provides a reason to think that true belief is valuable from one standpoint, and that justified belief is valuable from another standpoint, and similarly for other epistemic concepts. The value of the concept of knowledge is that it provides an economical way of talking about many (...) epistemic concepts that are valuable in itself from one standpoint or another. In this way knowledge is like a Swiss Army Knife; a Swiss Army Knife is not useful as such on any occasion, but it provides an efficient way of carrying around different tools that are useful in themselves on different occasions.

Does Frege have a metatheory for his logic? There is an obvious and uncontroversial sense in which he does. Frege introduces and discusses his new logic in natural language; he argues, in response to criticisms of Begriffsschrift, that his logic is superior to Boole's by discussing formal features of both systems. In so far as the enterprise of using natural language to introduce, discuss, and argue about features of a formal system is metatheoretic, there can be no doubt: Frege has (...) a metatheory. There is also an obvious and uncontroversial sense in which Frege does not have a metatheory for his logic. The model theoretic semantics with which we are familiar today are a post-Fregean development. The question I address in this paper is, does Frege have a metatheory in the following sense: do his justifications of his basic laws and rules of inference employ, or even require, ineliminable use of a truth predicate and metalinguistic variables? My answer is ‘no’ on both counts. I argue that Frege neither uses, nor has any need to use, a truth predicate or metalinguistic variables in his justifications of his basic laws and rules of inference. Quine's famous explanation of the need for semantic ascent simply does not apply to Frege's logic. The purpose of the discussions that are typically understood as constituting Frege's metatheory is, rather, elucidatory. And once we see what the aim of these particular elucidations is, we can explain Frege's otherwise puzzling eschewal of the truth predicate in his discussions of the justification of the laws and rules of inference.

In lieu of an abstract, here is a brief excerpt of the content:Lack of Autonomy: A View From the InsideSteve Weiner (bio)Keywordsagency, autonomy, deficit, determinismThe most vivid and truly overwhelming response I have to all arguments stressing agency/autonomy, that is, what lay people call free will, is this: that I’ve never had the sensation of acting autonomously since the onset of my mental illness on August 28, 1965. I have never been comfortable with saying that “I made a choice,” (...) or with other people either lecturing me or attempting to reassure me, often at the same time, by saying that I acted with autonomy/primary agency, as it were. That is my overwhelming subjective experience. I usually refrain from attempting to make a general case for determinism about myself or the universe in general, although, again, I feel far more determined than free. (I would note that Mary Midgley [2006] points out that the word determined and the concept, by extension, of determinism have two different meanings in say, social theory and geometry.)One strong criticism of this article I would put forward is that the Davidson and Shahan seemed to mention only depression among many diagnoses to make their case, although their French mentors/ co-thinkers apparently focused on schizophrenia, however unusually defined by them. In obsessive-compulsive disorder, we all have the very strong impression of the obsessive thoughts having been forced into our mind by something or someone else. My impression is that we all engage in our warding-off rituals, especially in the later, most frequent, most ritualistic repetitions, “against our will.”My most frequent diagnoses over the decades have been paranoid schizophrenia and schizoaffective disorder, and I more or less agree most of the time with those labels. I find Louis Sass’ “discovery” that our delusions are better thought of as semi-delusions with our simultaneously believing and not believing them, and our usual failure to take action on them, pretty well describes my own long-term experience. I know he is insistent on ascribing some degree of agency/whole personality involvement to us as compared with the standard National Alliance on Mental Illness/biological model, but I feel that he is getting closer to most of the “truth” when he talks about a subtle interweaving of affliction/deficit and agency.The authors’ reliance on French thinkers almost inevitably sends me back to a once-prominent French intellectual, one of my favorite writers Albert Memmi, the Tunisian-Jewish born socialist and Zionist. In a book that mentions The Story of O, (Memmi 1984) a story of extreme sexual submission or masochism, he makes the striking remark that the mentally ill are “oppressed from within.” I have spoken of this often because it seems to touch perfectly on my experience and that of fellow mentally ill people I have met. From the perspective of the outsider, it seems that the whole [End Page 237] and integrated person is involved in every behavior. What looks like agency to others, especially when it comes to undesirable behaviors, when experienced from within, is actually a situation of affliction from a seemingly autonomous place. We experience this as coming, yes, from within us, but not ultimately of us.I cannot be sure, but a belief in some degree of metaphysical choice from the beginning of one’s life seems to me the only way the authors of this article can firmly, enthusiastically come down on the side of agency as opposed to deficit/malfunction in trying to explain human problems. In contrast, I suppose I could be called a physicalist. I have noticed that physical substances (alcohol, caffeine, psychiatric drugs) have such a vivid and consistent effect on my mind that it makes sense to me to conclude that yes, mind is probably ultimately reducible to brain/body/experience of the senses. That is my private opinion based on experience as mediated through knowledge/intellect.One final point: Despite the (almost certainly) radical left politics of the authors, as an officially disabled person almost completely dependent on the welfare state, I fear that in competitive individualist America, the authors’ hoped-for far greater emphasis on autonomy will feed into popular “blame the victim” ideology. I believe... (shrink)

SummaryBy now, the story of T. D. Lysenko's phantasmagoric career in the Soviet life sciences is widely familiar. While Lysenko's attempts to identify I. V. Michurin, the horticulturist, as the source of his own inductionist ideas about heredity are recognized as a gambit calculated to enhance his legitimacy, the real roots of those ideas are still shrouded in mystery. This paper suggests those roots may be found in a tradition in Russian biology that stretches back to the 1840s—a tradition inspired (...) by the doctrines of Jean-Baptiste Lamarck and Etienne and Isidore Geoffroy Saint-Hilaire. The enthusiastic reception of those doctrines in Russia and of their practical application—acclimatization of exotic life forms—gave rise to the durable scientific preoccupation with transforming nature which now seems implicated in creating the context for Lysenko's successful bid to become an arbiter of the biological sciences.

I propose that testimony is subject to a norm that is backed by a credibility sanction: whenever the norm is violated, it is appropriate for the testifier to lose some credibility for their future testimony. This is one of a family of sanction-based norms, where violation of the norm makes it appropriate to lose some power; in this case, the power to induce belief through testimony. The applicability of the credibility norm to testimony follows from the epistemology of testimony, in (...) that false or unjustified testimony weakens the reason for belief that is provided by the speaker's future testimony.

I argued that Frege does not have a metatheory in the following sense: the justifications he offers for his basic laws and rules of inference neither employ nor require a truth-predicate or metalinguistic variables. In ‘Does Frege Use a Truth-predicate in his "Justification" of the Laws of Logic?’, Dirk Greimann disputes this. As Greimann interprets Frege, (i) Frege's remarks commit him to giving a metatheoretic justification of the basic laws and rules of his logic, and (ii) Frege actually gives such (...) a justification in the early sections of Grundgesetze—although the truth-predicate that Frege employs is a non-standard one: it is neither a predicate that holds of all and only true sentences nor a predicate that holds of all and only true thoughts. I argue that Greimann's interpretation is not, in the end, true to the text, and that his non-standard view of what is required of a Tarskian truth-predicate is ultimately not viable. (shrink)

Frege wanted to define the number 1 and the concept of number. What is required of a satisfactory definition? A truly arbitrary definition will not do: to stipulate that the number one is Julius Caesar is to change the subject. One might expect Frege to define the number 1 by giving a description that picks out the object that the numeral '1' already names; to define the concept of number by giving a description that picks out precisely those objects that (...) are numbers. Yet Frege appears to do no such thing. Indeed, when he defends his definitions, he does not argue that they pick out objects that we have been talking about all along-the issue never comes up. The aim of this paper is to explain why. I argue that, on Frege's view, our numerals do not, antecedent to his work, name particular objects. This raises an obvious question: If (like 'Odysseus') the numerals do not name particular objects, how can Frege write (as he does) as if sentences in which numerals appear state truths? One central concern of this paper is exegetical-to answer these questions. But my aim is not solely exegetical. For these questions direct us to something that, I believe, creates only an apparent problem for Frege but an actual problem for many contemporary philosophers: the assumption that singular terms appearing in statements about the world must actually have referents. Another aim of this paper is to suggest that the problem-as well as a solution that can be found in Frege's writings-should be of import to contemporary philosophers. (shrink)

I argue that there is a wide variety of epistemic norms, distributed along two different spectra. One spectrum runs from the ideal to the practical and concerns the extent to which it is possible to follow the norm given our cognitive and epistemic limitations. The other spectrum runs from thin to thick and concerns the extent to which the norm concerns facts about our beliefs over and above the content of the belief. Many putative epistemic norms, such as truth and (...) various conceptions of justification, can be found at different points on the spectra. There is no single obvious privileged point from which to say any of these norms is more fundamental than the others, though there may be some reason to doubt that some of the norms are intrinsically interesting.

This essay critically examines the Assurance View of testimony as put forth by Angus Ross (1986) and Richard Moran (1999). The Assurance View holds that someone who offers testimony gives the hearer a non-evidential justification for belief by assuming responsibility for the truth of her testimony. I agree that testimonial justification depends on the teller’s assumption of her responsibility for her testimony, but argue that it is nevertheless evidential justification. Testimonial justification is a sort of evidence that is within the (...) teller’s power to create or withhold at will, and that power is essential to the justification. (shrink)

Why did Frege look for the foundations of arithmetic in logic? Robin Jeshion has argued against several proposed answers, mine among them, and offered one of her own. In response, I argue that (i) Jeshion's own interpretation does not work: it is unsupported by the text and fails to answer the question; (ii) while it is not my view that Frege is motivated solely by philosophical concerns, his motivation cannot be divorced from his belief that foundations for science must show (...) whether its truths are analytic or synthetic, a priori or a posteriori; (iii) it must (for Frege) be evident from the content of a primitive truth to which of these categories the truth belongs.

How a human observer perceives duration depends on the amount of events taking place during the timed interval, but also on psychological dimensions, such as emotional-wellbeing, mindfulness, impulsivity, and rumination. Here we aimed at exploring these influences on duration estimation and passage of time judgments. One hundred and seventeen healthy individuals filled out mindfulness (FFMQ), impulsivity (BIS-11), rumination (RRS), and depression (BDI-sf) questionnaires. Participants also conducted verbal estimation and production tasks in the multiple seconds range. During these timing tasks, subjects (...) were asked to read digits aloud that were presented on a computer screen. Each condition of the timing tasks differed in terms of the interval between the presentation of the digits, i.e., either short (4-s) or long (16-s). Our findings suggest that long empty intervals (16-s) are associated with a relative underestimation of duration, and to a feeling that the time passes slowly, a seemingly paradoxical result. Also, regarding more mindful individuals, such a dissociation between duration estimation and passage of time judgments was found, but only when empty intervals were short (4-s). Relatively speaking, more mindful subjects showed an increased overestimation of durations, but felt that time passed more quickly. These results provide further evidence for the dissociation between duration estimation and the feeling of the passage of time. We discuss these results in terms of an alerting effect when empty intervals are short and events are more numerous, which could mediate the effect of dispositional mindfulness. (shrink)

It is widely assumed that the methods and results of science have no place among the data to which our semantics of vague predicates must answer. This despite the fact that it is well known that such prototypical vague predicates as ‘is bald’ play a central role in scientific research (e.g. the research that established Rogaine as a treatment for baldness). I argue here that the assumption is false and costly: in particular, I argue one cannot accept either supervaluationist semantics, (...) or the criticism of that semantics offered by Fodor and Lepore, without having to abandon accepted, and unexceptionable, scientific methodology.

Frege is celebrated as an arch-Platonist and arch-realist. He is renowned for claiming that truths of arithmetic are eternally true and independent of us, our judgments and our thoughts; that there is a third realm containing nonphysical objects that are not ideas. Until recently, there were few attempts to explicate these renowned claims, for most philosophers thought the clarity of Frege's prose rendered explication unnecessary. But the last ten years have seen the publication of several revisionist interpretations of Frege's writings (...) — interpretations on which these claims receive a very different reading. In Frege on Knowing the Third Realm, Tyler Burge attempts to undermine this trend. Burge argues that Frege is the very Platonist most have thought him — that revisionist interpretations of Frege's Platonism, mine among them, run afoul of the words on Frege's pages. This paper is a response to Burge's criticisms. I argue that my interpretation is more faithful than Burge's to Frege's texts. (shrink)

I related the following story to my large undergraduate class: “Johnny Jones was born with an impulsive temperament. On the way home one day he found a gun that had apparently been thrown away. He then went to rob a bank. The bank had just hired a security guard for protection. When Johnny attempted the robbery he was confronted by the guard and fatally shot him.” I then asked the students in the class to select one of the following.

My question in this talk is “Does Knowledge Matter?” Before I give you my answer —which is “not in itself,” roughly—I need to explain exactly what the question means. Think of epistemology as studying our beliefs and the process of inquiry by which we arrive at them.1 There will be many ways of sorting our beliefs, in themselves or with reference to the inquiry that led to them. Some of these won’t be particularly interesting. No one much cares whether a (...) particular belief is the product of an inquiry that began on a Tuesday. We do care about whether a belief arose from an inquiry that was wellconducted (whatever that means); it reflects on how good the believer is as a believer. The question is: Should we care whether a belief counts as knowledge? Here I’m thinking of ‘knowledge’ as we intuitively judge it when we’re not thinking about philosophical concerns; including the judgment that (at least many) people make that knowledge is lacking in Gettier cases. So: When we evaluate a belief, should we care whether it’s knowledge, including the avoidance of Gettier cases? Mark Kaplan (1985) has given an argument that we shouldn’t care. Suppose someone has a Gettiered belief; it’s justified and true but fails to amount to knowledge because of a false lemma or some such. Kaplan points out that this can’t lead to any criticism of your methods of inquiry. Ex hypothesi your belief is justified; the conduct of your inquiry was entirely proper. Nor (though Kaplan does not emphasize this point) is your belief erroneous. Kaplan’s conclusion is that the concept of knowledge does not.. (shrink)

In Knowledge and Lotteries, Hawthorne argues for a view on which whether a speaker knows that p depends on whether her practical environment makes it appropriate for her to use p in practical reasoning. It may seem that this view yields a straightforward account of why knowledge is important, based on the role of knowledge in practical reasoning. I argue that this is not so; practical reasoning does not motivate us to care about knowledge in itself. At best, practical reasoning (...) motivates us to care about several other concepts in themselves, and ascriptions of knowledge provide economical summaries of these independently important desiderata.

It has been claimed that justification, conceived traditionally in an internalist fashion, is not an epistemologically important property. I argue for the importance of a conception of justification that is completely dependent on the subject’s experience, using an analogy to advice. The epistemological importance of a property depends on two desiderata: the extent to which it guarantees the epistemic goal of attaining truth and avoiding falsehood, and the extent to which it depends only on the information available to the believer. (...) The traditional intermalist notion of justification completely satisfies the second desideratum and largely satisfies the first. (shrink)

Testimony is an indispensable way of gaining knowledge and also a voluntary act for which the teller can be held responsible. This dissertation analyzes these two aspects of testimony, the epistemological and the normative. Indeed, it argues that these two aspects cannot be separated: A satisfactory account of testimony's epistemology must allow for testimony's normative status, while an account of testimony's normative status can be derived from testimony's epistemology. ;Epistemologically, the general reliability of testimony should be treated differently from the (...) reliability of particular pieces of testimony. We are justified in believing that testimony is generally reliable, without needing evidence to that effect. This avoids the problems that would arise from attempting to gather evidence for testimony's general reliability. Particular pieces of testimony, however, can only provide a justification for belief by providing evidence for what is told. This view about particular pieces of testimony faces the problem of how the teller can present her testimony as evidence while accepting responsibility for it, and how the hearer can take testimony as evidence while holding the hearer responsible for it. ;To solve this problem, I give an account, based on inference to the best explanation, of the specific way testimony provides evidence for what is told. To see testimony as evidence for what is told, we must explain it in terms of the reasons people have for choosing to say one thing rather than another. On this account, the evidence that testimony provides depends on the teller's choice to assume responsibility for her testimony, rather than precluding that assumption of responsibility. ;On the other hand, the epistemology of testimony imposes certain norms on the act of telling someone something. The teller is responsible for the truth of her testimony, in that she stakes her future credibility on its truth. Loss of credibility would count as a sanction for violating the responsibility to tell the truth, because a teller ordinarily intends her testimony to be believed. This responsibility to tell the truth is derived from the epistemology of testimony. (shrink)

Background Childhood cancers affect about 350 children every year in Sweden and are life-threatening diseases. During the treatment period, situations arise that can become morally challenging for the child. When knowing children’s values and morally challenging situations in childhood cancer care, targeted ethics support could be developed and used in care. Aim To explore children’s values and moral dilemmas ​​when undergoing cancer treatment. Methods This is a qualitative study based on empirical data. The data collection was conducted through three focus (...) group interviews and six individual interviews with children between 10 and 18 years (n = 16). A content analysis methodology was used to generate themes. Children who were/have been treated for cancer at three childhood cancer centres in Sweden were invited to participate. The study was approved by the Swedish Ethical Review Authority. The children’s participation was based on voluntariness and consent/assent. Findings During the analysis, five themes of values emerged: Personal relationships, Bodily ease and identity, Feeling in control and being involved, Positive distractions and Right care that is needed. Their moral dilemmas were thematized into: Should I consider others or not? Should I rest or not? and Should I refuse treatment or not? Conclusion Children undergoing cancer treatment want to have personal relationships with healthcare professionals. Their moral dilemmas were about questioning their own physical and psychological well-being against their expectations, the values of others and the treatment required. Further research is needed to understand how to deal with moral dilemmas in children undergoing cancer treatment. (shrink)

Knowledge of eukaryotic life cycles and associated genome dynamics stems largely from research on animals, plants, and a small number of “model” (i.e., easily cultivable) lineages. This skewed sampling results in an underappreciation of the variability among the many microeukaryotic lineages, which represent the bulk of eukaryotic biodiversity. The range of complex nuclear transformations that exists within lineages of microbial eukaryotes challenges the textbook understanding of genome and nuclear cycles. Here, we look in‐depth at Foraminifera, an ancient (∼600 million‐year‐old) lineage (...) widely studied as proxies in paleoceanography and environmental biomonitoring. We demonstrate that Foraminifera challenge the “rules” of life cycles developed largely from studies of plants and animals. To this end, we synthesize data on foraminiferal life cycles, focusing on extensive endoreplication within individuals (i.e., single cells), the unusual nuclear process calledZerfall, and the separation of germline and somatic function into distinct nuclei (i.e., heterokaryosis). These processes highlight complexities within lineages and expand our understanding of the dynamics of eukaryotic genomes. (shrink)

In this paper I argue against a criticism by Matthew Weiner to Grice’s thesis that cancellability is a necessary condition for conversational implicature. I argue that the purported counterexamples fail because the supposed failed cancellation in the cases Weiner presents is not meant as a cancellation but as a reinforcement of the implicature. I moreover point out that there are special situations in which the supposed cancellation may really work as a cancellation.

This paper considers whether Kant’s aesthetics withstands the challenge of conceptual art. I begin by looking at two competing views of conceptual art by recent philosophers, before settling on an ‘inclusive’ view of the form: conceptual art includes both ‘strong’ and ‘weak’ non-perceptual art (NPA). I then set out two kinds of conceptual complexity that I argue are implicated by all aesthetic judgements of art (as art) on Kant’s view: the concept of art itself, and the idea the work is (...) meant to express (dependent beauty and aesthetic ideas, respectively). I go on to demonstrate the applicability of Kant’s aesthetics to conceptual art by considering two works by Lawrence Weiner, which I take to be a work of work of weak and strong NPA respectively.

John N. Williams (1994) and Matthew Weiner (2005) invoke predictions in order to undermine the normative relevance of knowledge for assertions; in particular, Weiner argues, predictions are important counterexamples to the Knowledge Account of Assertion (KAA). I argue here that they are not true counterexamples at all, a point that can be agreed upon even by those who reject KAA.

Joan Weiner (2007) has argued that Frege’s definitions of numbers are linguistic stipulations, with no content-preserving or ontological point: they don’t capture any determinate content of numerals, as they have none, and don’t present numbers as preexisting objects. I show that this view is based on exegetical and systematic errors. First, Idemonstrate that Weiner misrepresents the Fregean notions of ‘Foundations-content’, sense, reference, and truth. I then consider the role of definitions, demonstrating that they cannot be mere linguistic stipulations, (...) since they have a content-preserving, ontological point, and a decompositional aspect; Frege’s project of logical analysis and systematisation makes no sense without definitions so understood. The pivotal ontological role of elucidations is also explained. Next, three aspects of definition are distinguished, the informal versus the formal aspect, and the aspect of definition achieved through the entire process of systematisation, which encompasses the previous two and is little discussed in the literature. It is suggested that these insights can contribute to resolving some of the puzzles concerning the tension between the epistemological aim of logicism and Frege’s presentation of definitions as arbitrary conventions. Finally, I stress the interdependence between the epistemological and ontological aspects of Frege’s project of defining number. (shrink)

This paper addresses Frege's discussion of illogical thought in the introduction to Basic Laws of Arithmetic. After a brief introduction, I discuss Frege's claims that logic is normative vis-à-vis thought, and not descriptive, and his opposition to the idea that logical laws express psychological necessities. I argue that these two strands of Frege's polemic against psychologism constitute two motivating factors behind his allowing for the possibility of illogical thought. I then explore a line of thought—originally advanced by Joan Weiner—according (...) to which Frege should have rejected illogical thought as not constituting a genuine possibility. I argue that, once developed, this line of thought constitutes an important correction (moreover, one that is consistent with his two aforementioned anti-psychologistic strands) to Frege's own response to the possibility of illogical thought. -/- .

In lieu of an abstract, here is a brief excerpt of the content:Nonplaces:An Anecdoted Topography of Contemporary French TheoryBruno Bosteels (bio)In its juridical sense, a non-lieu is a judgment that suspends, annuls, or withdraws a case without bringing it to trial. It is thus a judgment that announces or enunciates that there will be no judgment as to guilt or innocence, a finding that there is no place to judge. It therefore renders justice by refusing to render it under the (...) law, which it does when it pronounces or enunciates the non-lieu.—Peggy Kamuf, "Béance"1Inside the Spatial TurnIf modernity will always be remembered as an era dominated by questions of time and history, then perhaps the steady waning of modern ideals invites us to think of the entry into something called the postmodern as a passage dominated by questions of space and geography. As Michel Foucault once famously observed in a 1967 conference paper, first published two decades ago: "Perhaps we might say that some of the ideological conflicts that animate today's polemics oppose the pious descendants of time and the willful inhabitants of space" ["Of Other Spaces" 22]. This conflict over time and space presupposes a much larger argument that is not only historical but also methodological in nature. What is at stake is both a question of the passage, or transition, from modernity to postmodernity, if that is indeed what we decide to name modernity's aftermath, and a question of the theoretical consequences that follow from giving precedence to space over time in treating this very transition. With regard to this second question, too, Foucault's work stands as exemplary insofar as he was able to show the degree to which a vital emphasis on space, geography, and territoriality [End Page 117] forces us to take leave of the modern paradigm of consciousness—typically associated with the category of time and its unfolding in the mind or spirit—in favor of a situated understanding of knowledge, subjectivity, and power. "Metaphorizing the transformations of discourse in a vocabulary of time necessarily leads to the utilisation of the model of individual consciousness with its intrinsic temporality," Foucault observes in an interview with the editors of the French journal of geography Hérodote, and he continues: "Endeavouring on the other hand to decipher discourse through the use of spatial, strategic metaphors enables one to grasp precisely the points at which discourses are transformed in, through and on the basis of relations of power" ["Questions on Geography" 69–70]. Whether real or metaphorical, a willful displacement of our categorial apparatus from time to space thus might enable one to avoid the idealist temptation inherent in a strictly discursive or textual model, by inscribing all discourses and practices in the geopolitics of power relations.My aim in the following pages is not to go over the much-discussed shift from time to space once more, even as I take advantage of several of its methodological principles along the way. Instead, I want to map out a momentous change of perspective that has been taking place over the past few decades within the parameters of the so-called spatial turn itself. In fact, if and when modernity is coming to an end, both in the sense of completing itself and of revealing its character as a finite historical entity, not only does whatever shape critical thought takes in the face of this turnabout need to be securely fastened onto specific places and spaces but, if we are to believe a growing number of authors, particularly but by no means exclusively in France, the study of art, literature, politics, philosophy, and even anthropology would also require a thorough consideration of so-called "nonplaces" as a rigorous category for critical thinking today [for a brief discussion of the use of "nonplace" in Anglo-American anthropology, including Melvin M. Webber's notion of "nonplace urban realm" from the mid-1960s, see Weiner]. In the end, these proponents of the nonplace confront us with one disarmingly simple question: how can critical thinking in the present time respond to the task of having to work through whatever lies outside of the order that is actually in place?The Exhaustion of...

As more and more decisions that have a significant ethical dimension are being outsourced to AI systems, it is important to have a definition of moral responsibility that can be applied to AI systems. Moral responsibility for an outcome of an agent who performs some action is commonly taken to involve both a causal condition and an epistemic condition: the action should cause the outcome, and the agent should have been aware -- in some form or other -- of the (...) possible moral consequences of their action. This paper presents a formal definition of both conditions within the framework of causal models. I compare my approach to the existing approaches of Braham and van Hees (BvH) and of Halpern and Kleiman-Weiner (HK). I then generalize my definition into a degree of responsibility. (shrink)

I argue that discussions of Frege’s conception of elucidation have suffered from a conflation of two distinct issues: elucidation of primitive scientific terms, and elucidation of the logical categories. The former seeks to bring us to grasp the Bedeutung of terms that stand at the beginning of the chain of definitions of a scientific system. The latter cannot be understood on the model of securing agreement in Bedeutung at all. I show how existing discussions of Fregean elucidation insufficiently take this (...) difference into account. I adumbrate what I take to be a more accurate understanding of Fregean elucidation of the logical categories, starting from the observation that Frege, when engaged in such elucidation, consistently reverts to talking about signs. Frege, I argue, takes signs to possess logical features, and it is these logical features which his elucidations are meant to help us to grasp. For Frege, the nature of the logical categories lies in the signs. In this way, I argue, Frege’s approach to elucidating the logical categories is incompatible with a realist conception according to which there is a logical order of reality that is prior to the logical order of language.

CHRISTOPHER PINCOCK, Department of Philosophy, Purdue University, West Lafayette, IN 47907, USA The volume under review contains fifteen new essays by some of the most influential scholars of the history of early analytic philosophy. The focus of the essays is, as the editor says in the preface, ‘the work of Gottlob Frege and of Ludwig Wittgenstein (mostly the early Wittgenstein), as well as various ties between them’ (p. x). The essays are divided into four parts. The first part, ‘Background and (...) General Themes’, contains essays by E. Reck, G. Gabriel and S. Gerrard. The second part on Frege has contributions by H. Sluga, S. Shieh, M. Ruffino and J. Weiner. Essays on the relation between Frege and the early Wittgenstein by W. Goldfarb, D. Macbeth, T. Ricketts and C. Diamond comprise the third part. The volume concludes with essays by I. Proops, J. Floyd, M. Ostrow and J. Conant on the early Wittgenstein. This volume is an important contribution to our understanding of Frege and the early Wittgenstein and should prove a help to specialists in the history of analytic philosophy. I have chosen to briefly discuss seven of these essays with an emphasis on topics in the history and philosophy of logic. Reck’s opening essay, ‘Wittgenstein’s “Great Debt” to Frege: Biographical Traces and Philosophical Themes’, gives a helpful overview of our current knowledge of the contacts between Frege and Wittgenstein. Reck argues quite persuasively for the conclusion that Wittgenstein engaged with Frege’s work throughout his philosophical career. The depth of this engagement is in-. (shrink)

In this introduction to the special section on the attributional approach to emotion and motivation, the character of Weiner’s attributional theory as an appraisal theory is discussed. I argue that the theory, although focusing on appraisal dimensions related to causal attribution, is actually a fairly general appraisal theory of emotion. Distinctive features of the attributional approach are its pioneering role in emotion research, its emphasis on the functional role of emotions, particularly for the motivation of action, and the existence (...) of a large supportive data base. Given the solid evidence compiled by attributional researchers for emotion-specific effects of emotion on motivation, I propose that future research should focus on the details of the mental mechanisms through which emotions affect motivation, and formulate five questions that could guide this inquiry.

Poreskoro, with three cat and four dog heads and a snake with a forked tongue as his tail, is responsible for epidemics of contagious diseases in Romany folklore. The Pishachas of Vedic mythology lurk in charnel houses and graveyards, waiting for humans to infect with madness. In Christian demonology, Pythius is known as the ruler of the eighth circle of the Inferno, bestowing heinous and unspeakable tortures on those who have committed fraud. Demons are the stuff of legends, and they (...) are everywhere in mythology and theology. These are just three of the more than thirty I counted that start with the letter P.How lucky we are for the advent of science. A rational tonic, it scatters our demons, demystifying the world for us—or so, at least, we think. As Canales brilliantly shows in this book, our assumption has been far off the mark. In physics, computer science, genetics, neuroscience, and economics, not to mention in the very foundations of rationality itself, an underworld of imaginary creatures has sustained and continues to inhabit modern science. Scientific demons appear in many guises: as atomic and subatomic particle manipulators, as feedback and parallel-processing experts, as messengers who can travel faster than the speed of light, as computer-code spies, gene and bit selectors in evolution and in informatics, as triggers of cascades from the nano level to the level of full-blown ecological and astrophysical theaters. By inventing them, we have learned that causality does not always hold at the level of atoms, that the speed of message transmission is limited, that living systems spend energy, that perpetual-motion machines are impossible, and that there are corners of the universe we have not imagined.We have all heard of Laplace's Demon, and Maxwell's, but who knew that, borrowing from physics, the historian Henry Adams considered the action of demons in geopolitics or that the economist Paul Samuelson analyzed their role in producing more efficient markets? Who knew that the generation that gave us the Internet and artificial intelligence were tasked by their teachers in graduate school to insert as many demons as possible into their programs? Who among us has heard of Darwin's Demon, or Maxwell-Szilárd-Brillouin's, or Monod's, or Loschmidt's? Who is aware of Norbert Weiner's use of demons in conceptualizing cybernetics, or of the great scholar of Kabbalah Gershom Scholem's comparison between Israel's superfast computers and the Golem?As Canales shows convincingly, it has been difficult for both historians and scientists to countenance demons in science, and so they have been written out, in many ways and many instances, of the histories of which they are part and parcel. Thomas Kuhn and even the more radical philosopher Paul Feyerabend both failed to acknowledge in their social critiques of science the extent to which an imaginary underworld of beings has been constitutive of the modern scientific imagination. Ironically, it was the man who provided a hard-and-fast criterion by which to distinguish scientific and nonscientific pursuits, Karl Popper, who ultimately saw the light. Revisiting his classic book The Logic of Scientific Discovery from 1934, he clarified in Postscript to the Logic of Scientific Discovery in 1982 the extent to which every historical era has been characterized by a particular demon. We moderns believe that science is about facts and numbers, but we are mistaken. As Canales beautifully summarizes the stakes of her project, “What first sets science on its path of discovery—then as now—is the continued use of the imagination.”Tracking the fate of demons in modern thought from Descartes to Lord Kelvin to H. G. Wells to David Bohm, and from Conrad Hal Waddington to Henry Compton to Stephen Hawking and Steven Pinker, Bedeviled assumes that the demons of the church or of paganism and the demons of science differ and resemble each other in ways that can be usefully elaborated. What is more crucial, however, is how such demons become real, how they morph from fears to hopes, and from thought experiments into real experiments, and ultimately to things in this world like computer programs, transistors, and nanorobots. From weather systems to messenger RNAs to black holes, demons emerge everywhere. The hard question is: How does the imagination actually drive discovery and understanding? How does it change our world?Perhaps it has been a sidetrack to consider whether we have or have never been modern. Clearly, what reason will not allow, it perennially recruits for a shadowland that helps us to better see our world. Rather than aiming to exorcise science, one day, of all of its methodological and epistemological ghosts, perhaps we might make peace with the notion that every culture struggles with distinguishing truth from falsehood in its own unique way. Such struggles are sensitive to their times and are accomplished through leaps of imagination. But fear not: the debunking of “Western rationality” casts no wet blanket on the project of Enlightenment. If anything, as Canales writes, “an account of science that considers how scientists themselves do science only risks adding new insights into our repertoire of knowledge.” Perhaps, therefore, there is solace to be gained from the dictum, Always choose the Devil you know. Ultimately, there may be no other way forward. (shrink)

In Grundgesetze der Arithmetik, Frege tried to show that arithmetic is logical by giving gap-free proofs from what he took to be purely logical basic laws. But how do we come to judge these laws as true, and to recognize them as logical? The answer must involve giving an account of the apparent arguments Frege provides for his axioms. Following Sanford Shieh, I take these apparent arguments to instead be exhibitions: the exercise of a logical capacity in order to bring (...) us into a state of judgement. I provide an account of what sort of inferential capacities are at play in such exhibitions, and explain how they lead us to judge that Frege’s primitive laws are general and undeniable. I will also situate my account with respect to other rival interpretations, particularly the elucidatory interpretations of Joan Weiner and Thomas Ricketts. (shrink)

In his recent Philosophers’ Imprint paper “The (mostly harmless) inconsistency of knowledge attributions” [Weiner, 2009], Matt Weiner argues that the semantics of the expression “knows that”, as it is used in attributions of knowledge like “Hannah knows that the bank will be open,” are inconsistent, but that this inconsistency is “mostly harmless.” He presents his view as an alternative to the invariantist, contextualist and relativist approaches currently prevalent in the literature, (e.g. [Stanley, 2005], [DeRose, 1995], [Hawthorne, 2006], [MacFarlane, (...) 2005]) and argues that it avoids important disadvantages of each. Yet in calling the supposed inconsistency of knowledge attributions “mostly harmless”, Weiner implies that his view does not have new disadvantages of its own. My purpose in the present paper is to argue that the inconsistency and harmlessness theses cannot be jointly maintained: if we accept that the semantics of ‘know’—or indeed any word—are inconsistent, then we face a dilemma: one horn is dialetheism, the view that there there are true contradictions, the other is the view that that semantic competence in English requires belief in, or similar commitment to, falsehoods. I will argue that neither of these options is well described as “mostly harmless.” The paper is structured as follows: in the first part I present Weiner’s view and his arguments for it. Then in section 2 I compare the question of whether the semantics of ‘knows that’ are inconsistent to the much older controversy over whether the semantics of the expression ‘is true’ are inconsistent. In section 3 I will present Hans Herzberger’s arguments from the 1960s for thinking that no expression in a natural language can have inconsistent semantics. Finally, in section 4 I argue that although Herzberger’s argument seems anachronistic today, both contemporary ways of avoiding his conclusion have significant disadvantages. (shrink)

Observer intervention can be useful in preventing workplace harassment. This research extends the workplace harassment literature by using the Jones et al. ( 1984 ) stigma dimensions and related research (Summers et al., 2018 ; Weiner et al., 1988 ) to highlight differences and similarities between three forms of harassment (i.e., sexual, sexual orientation, religious) and their relations to observer intervention in workplace harassment incidents. Results from two studies reveal differences (controllability, stability, visibility) and similarities (disruptiveness, peril, bystander efficacy, (...) position authority) across forms of harassment in associations with observer intervention. Several differences across harassment of different religious subgroups (Atheists, Christians, Jews, Muslims) are also noted. We explore the implications of these findings and suggest future directions for research in the observer intervention and workplace harassment literature. (shrink)

La categoría ‘arte conceptual’ se aplica a una gran cantidad de obras de arte contemporáneo. El artista Sol LeWitt introdujo el término en la jerga del arte al describir obras de arte donde “la idea o el concepto es el aspecto más importante de la obra” (LeWitt 1967: 79, traducción mía). Inicialmente, el término se utilizó para referirse a obras producidas entre finales de los años sesenta y principios de los setenta por artistas como Sol LeWitt, Robert Barry, Lawrence (...) class='Hi'>Weiner, On Kawara, Joseph Kosuth, John Baldessari, el grupo Art & Language y otros (véase Lippard 1973). En España fueron relevantes el Grup de Treball, Zaj o Esther Ferrer entre otros. Más tarde se hizo evidente no solo que obras como Fuente (1917) de Marcel Duchamp – un urinario de porcelana, que fue firmado “R. Mutt” y presentado para una exposición de la Sociedad de Artistas Independientes – tenían mucho en común con aquellas producidas a finales de la década de 1960 y principios de la de 1970, sino también que obras de arte conceptual continuaron siendo producidas a lo largo de la década de 1970 y las décadas siguientes, hasta el punto de que podría argumentarse que gran parte del arte contemporáneo es, en cierta medida, conceptual. -/- Es característico de los primeros autores conceptuales el uso del lenguaje natural en obras que son en principio visuales o plásticas, como las frases de Weiner, las definiciones de Kosuth o los ensayos de Art&Language. Se trata de un interés por el significado y el lenguaje heredado de la semiótica y la filosofía analítica de la época. También señala el énfasis (a menudo exclusivo) de todas las obras de arte conceptual en el elemento conceptual, como ocurre en los dibujos y pinturas murales de LeWitt, donde el artista produjo las instrucciones para su ejecución, luego las realizó en colaboración con otros, o transfirió completamente a otros esta tarea. Otra característica de las primeras obras de arte conceptual es que los artistas no manipularon ningún material para producir un objeto (como en Fuente de Duchamp) o usaron materiales excéntricos como el lenguaje natural, su propio cuerpo -como en I am the locus (# 1) (1975) de Adrian Piper, una performance en la que la artista se pegó un bigote en la cara, se puso una peluca Afro y anteojos redondos con montura de alambre y caminó en las calles actuando como un hombre-, o el chocolate con el que Anya Gallaccio revistió las paredes de un viejo edificio agrícola en Stroke (2004), dejando que el público las tocara y que el chocolate se pudriese. -/- Debido a sus características inusuales, el arte conceptual plantea muchas preguntas filosóficas: sobre la definición de arte, sobre la ontología y los medios de las obras de arte y sobre nuestra experiencia apreciativa de ellas. En lo que sigue, presentaré brevemente cada uno de estos temas. (shrink)
