According to the thesis of transparency, subjects can attend only to the representational content of perceptual experience, never to the intrinsic properties of experience that carry this representational content, i.e., to “mental paint.” So far, arguments for and against transparency were conducted from the armchair, relying mainly on introspective observations. In this paper, we argue in favor of transparency, relying on the cognitive neuroscience of attention. We present a trilemma to those who hold that attention can be directed to mental (...) paint. Such attention is either first-order sensory, higher-order cognitive, or higher-order sensory attention. We argue that the notion of first-order sensory attention to mental paint is incompatible with the neuroscience of sensory attention; that higher-order cognitive attention to mental paint is irrelevant to transparency; and that the notion of higher-order sensory attention to mental paint has an apparently incoherent prediction. Via elimination, these considerations support the thesis of transparency. (shrink)

The paper argues that knowledge is not closed under logical inference. The argument proceeds from the openness of evidential support and the dependence of empirical knowledge on evidence, to the conclusion that knowledge is open. Without attempting to provide a full-fledged theory of evidence, we show that on the modest assumption that evidence cannot support both a proposition and its negation, or, alternatively, that information that reduces the probability of a proposition cannot constitute evidence for its truth, the relation of (...) evidential support is not closed under known entailment. Therefore the evidence-for relation is deductively open regardless of whether evidence is probabilistic or not. Given even a weak dependence of empirical knowledge on evidence, we argue that empirical knowledge is also open. On this basis, we also respond to the strongest argument in support of knowledge closure. Finally, we present a number of significant benefits of our position, namely, offering a unified explanation for a range of epistemological puzzles. (shrink)

A vibrant new translation of Seneca’s “On the Shortness of Life,” a pointed reminder to make the most of our time Who doesn’t worry sometimes that smart phones, the Internet, and TV are robbing us of time and preventing us from having a life? How can we make the most of our time on earth? In the first century AD, the Stoic philosopher Seneca the Younger offered one of the most famous answers to that question in his essay “On the (...) Shortness of Life”—a work that has more to teach us today than ever before. In How to Have a Life, James Romm presents a vibrant new translation of Seneca’s brilliant essay, plus two Senecan letters on the same theme, complete with the original Latin on facing pages and an inviting introduction. With devastating satiric wit, skillfully captured in this translation, Seneca lampoons the ways we squander our time and fail to realize how precious it is. We don’t allow people to steal our money, yet we allow them to plunder our time, or else we give it away ourselves in useless, idle pursuits. Seneca also describes how we can make better use of our brief days and years. In the process, he argues, we can make our lives longer, or even everlasting, because to live a real life is to attain a kind of immortality. A counterweight to the time-sucking distractions of the modern world, How to Have a Life offers priceless wisdom about making our time—and our lives—count. (shrink)

The idea that knowledge can be extended by inference from what is known seems highly plausible. Yet, as shown by familiar preface paradox and lottery-type cases, the possibility of aggregating uncertainty casts doubt on its tenability. We show that these considerations go much further than previously recognized and significantly restrict the kinds of closure ordinary theories of knowledge can endorse. Meeting the challenge of uncertainty aggregation requires either the restriction of knowledge-extending inferences to single premises, or eliminating epistemic uncertainty in (...) known premises. The first strategy, while effective, retains little of the original idea—conclusions even of modus ponens inferences from known premises are not always known. We then look at the second strategy, inspecting the most elaborate and promising attempt to secure the epistemic role of basic inferences, namely Timothy Williamson’s safety theory of knowledge. We argue that while it indeed has the merit of allowing basic inferences such as modus ponens to extend knowledge, Williamson’s theory faces formidable difficulties. These difficulties, moreover, arise from the very feature responsible for its virtue- the infallibilism of knowledge. (shrink)

The history of productivity of the κ-chain condition in partial orders, topological spaces, or Boolean algebras is surveyed, and its connection to the set-theoretic notion of a weakly compact cardinal is highlighted. Then, it is proved that for every regular cardinal κ > א1, the principle □ is equivalent to the existence of a certain strong coloring c : [κ]2 → κ for which the family of fibers T is a nonspecial κ-Aronszajn tree. The theorem follows from an analysis of (...) a new characteristic function for walks on ordinals, and implies in particular that if the κ-chain condition is productive for a given regular cardinal κ > א1, then κ is weakly compact in some inner model of ZFC. This provides a partial converse to the fact that if κ is a weakly compact cardinal, then the κ-chain condition is productive. (shrink)

Harman and Lewis credit Kripke with having formulated a puzzle that seems to show that knowledge entails dogmatism. The puzzle is widely regarded as having been solved. In this paper we argue that this standard solution, in its various versions, addresses only a limited aspect of the puzzle and holds no promise of fully resolving it. Analyzing this failure and the proper rendering of the puzzle, it is suggested that it poses a significant challenge for the defense of epistemic closure.

Let λ denote a singular cardinal. Zeman, improving a previous result of Shelah, proved that $\square _{\lambda}^{\ast}$ together with 2 λ = λ⁺ implies $\lozenge _{S}$ for every S ⊆ λ⁺ that reflects stationarily often. In this paper, for a set S ⊆ λ⁺, a normal subideal of the weak approachability ideal is introduced, and denoted by I[S; λ]. We say that the ideal is fat if it contains a stationary set. It is proved: 1. if I[S; λ] is fat, (...) then $\text{NS}_{\lambda ^{+}}$ ↾ S is non-saturated; 2. if I[S; λ] is fat and 2 λ = λ⁺, then $\lozenge _{S}$ holds; 3. $\square _{\lambda}^{\ast}$ implies that I[S; λ] is fat for every S ⊆ λ⁺ that reflects stationarily often; 4. it is relatively consistent with the existence of a supercompact cardinal that $\square _{\lambda}^{\ast}$ fails, while I[S; λ] is fat for every stationary S ⊆ λ⁺ that reflects stationarily often. The stronger principle $\lozenge _{\lambda ^{+}}^{\ast}$ is studied as well. (shrink)

Timothy Williamson has famously argued that the principle should be rejected. We analyze Williamson's argument and show that its key premise is ambiguous, and that when it is properly stated this premise no longer supports the argument against. After canvassing possible objections to our argument, we reflect upon some conclusions that suggest significant epistemological ramifications pertaining to the acquisition of knowledge from prior knowledge by deduction.

This paper applies the Klein Group form used by Rosalind Krauss in her essay, "Sculpture in the Expanded Field", to the field of ruins. The opposition utilized to create the ruin Klein Group is the opposition between vanished and intact. The paper proceeds by classifying and discussing each of the possibilities opened up by the expanded field: ruins (not-vanished ; not-intact), consecrated sites (vanished ; not-vanished), ruin-reproduction (vanished ; intact), and finally the "necroaesthetical ruin" (intact ; not-intact). The expanded field (...) and the political and aesthetic implications thereof are discussed primarily in conversation with Paolo Virno's "Deja Vu and the End of History," as well as Achille Mbembe's "Necropolitics" and Andreas Huyssen's "Nostalgia for Ruins.”.

Explores the moral struggles, political intrigues and violent vendettas that enmeshed Seneca, the ancient Roman writer and philosopher, in the brutal daily lives of the imperial family and the regime of his student, Nero.

There are few indulgences academics can crave more than to have their work considered and addressed by leading researchers in their field. We have been fortunate to have two outstanding philosophers from whose work we have learned a great deal give ours their thoughtful attention. Grappling with Stephen Yablo’s, and Juan Comesaña’s comments and criticisms has helped us gain a better understanding of our ideas as well as their shortcomings. We are extremely grateful to them for the attentiveness and seriousness (...) with which they have considered our arguments and to philosophical studies for giving us this opportunity. Given the substantive difference between the two response papers, there is not much beyond sincere gratitude that we can covey to them jointly. We will therefore address them in turn. (shrink)

According to an influential philosophical view I call “the relational properties view”, “perspectival” properties, such as the elliptical appearance of a tilted coin, are relational properties of external objects. Philosophers have assessed this view on the basis of phenomenological, epistemological or other purely philosophical considerations. My aim in this paper is to examine whether it is possible to evaluate RPV empirically. In the first, negative part of the paper I consider and reject a certain tempting way of doing so. In (...) the second, positive part of the paper I suggest a novel way of evaluating RPV empirically, relying on the influential object files framework. (shrink)

Under what conditions do women create places for women on the Internet? And what kinds of difficulties do they meet if they try to do so? These questions are studied by comparing two groups of women involved in the design of Amsterdam's digital city DDS. The female designers, who were involved as DDS was set up, did not want to pay attention to women's issues. This can be explained by looking at their position in feminist debates in Dutch society, their (...) position in the organization of which they were a part and their personal identity. The second group of women, who were part of a women's organization, differed in all these respects. Thus, they had no problems in wanting to pay specific attention to women in DDS by building a `Women's Square'. The problems of this second group of women were caused by the late stage at which they entered the design process. The ideas on gender and technology of the initial group of women had by then solidified in the script of DDS, making it hard for the second group to design the Women's Square in the way they wanted it. In this article it is argued that designers, women's organizations and subsidizing organizations should stimulate women's groups to get involved in the design of new technology at an early stage. From this case study, one can conclude that leaving women's issues to individual female designers is not an effective strategy. (shrink)

What kind of inquiry is management science? This paper compares two accounts — realist-oriented and constructivist-oriented — and proposes a third position. The realist view that scientific inquiry seeks knowledge of realities independent and outside of the knowing process is set against the constructivist view that scientific theorising creates accounts which develop our discourses without claiming knowledge of ‘deeper’ realities. It argues that ultimately we have no way of resolving this long-standing dispute. To move beyond the impasse it proposes a (...) trusting constructivist position, arguing that responsible theorising requires that inquirers develop discursive accountability and that the process of inquiry matters as much as its content. Finally it explores what such a view of accountability would mean for the relationship between scientists or ‘professionals’ and users of their research findings in organisations. (shrink)

It is relatively consistent with the existence of two supercompact cardinals that a special Aronszajn tree of height ${\aleph_{\omega_1+1}}$ is introduced by a cofinality-preserving forcing of size ${\aleph_3}$.

This paper proposes and develops the feelings of goals hypothesis (FGH). It has two aims: first, to describe the evolutionary function of emotional feelings (EFs), and second, to describe the content and the format of EFs. According to FGH, the evolutionary function of EFs is to enable motoric flexibility. Specifically, EFs are a component of a psychological mechanism that permits differential motoric reactions to the same stimulus. Further, according to FGH, EF is a special type of mental representation with the (...) content of an action goal, and with a non-motoric, non-conceptual format. This paper thoroughly clarifies the assumptions underlying FGH and discusses its theoretical implications and empirical predictions. (shrink)
