The norm of assertion, to be in force, is a social norm. What is the content of our social norm of assertion? Various linguistic arguments purport to show that to assert is to represent oneself as knowing. But to represent oneself as knowing does not entail that assertion is governed by a knowledge norm. At best these linguistic arguments provide indirect support for a knowledge norm. Furthermore, there are alternative, non-normative explanations for the linguistic data (as in recent work from (...) Van Elswyk). Direct arguments would rely on normative judgments about the permissibility or impermissibility of assertions with and without the speaker knowing the content asserted. John Turri's work experimental results purport to show that our norm of assertion is factive, and probably knowledge. But as a number of recent experimentalists (Kneer, Reuter and Broessel, Marsili and Wiegmann) have shown, Turri's results rely on the problemmatic use of 'should' as in 'Maria should assert that she owns a 1990 watch.' Correcting for this, these experimentalists provide strong evidence that our norm of assertion is not factive. The standard reply to evidence like this from the assertion of unlucky falsehoods is the excuse maneuver. But Marsili and Wiegmann, following Turri's protocol for testing for excuse validation, show that participants who judge that assertions unlucky falsehoods are permissible are not guilty of excuse validation. Given our current understanding of the experimental evidence, knowledge is not our norm of assertion. (shrink)

The EDPS Ethics Advisory Group (EAG) has carried out its work against the backdrop of two significant social-political moments: a growing interest in ethical issues, both in the public and in the private spheres and the imminent entry into force of the General Data Protection Regulation (GDPR) in May 2018. For some, this may nourish a perception that the work of the EAG represents a challenge to data protection professionals, particularly to lawyers in the field, as well as to companies (...) struggling to adapt their processes and routines to the requirements of the GDPR. What is the purpose of a report on digital ethics, if the GDPR already provides all regulatory requirements to protect European citizens with regard to the processing of their personal data? Does the existence of this EAG mean that a new normative ethics of data protection will be expected to fill regulatory gaps in data protection law with more flexible, and thus less easily enforceable ethical rules? Does the work of the EAG signal a weakening of the foundation of legal doctrine, such as the rule of law, the theory of justice, or the fundamental values supporting human rights, and a strengthening of a more cultural approach to data protection? Not at all. The reflections of the EAG contained in this report are not intended as the continuation of policy by other means. It neither supersedes nor supplements the law or the work of legal practitioners. Its aims and means are different. On the one hand, the report seeks to map and analyse current and future paradigm shifts which are characterised by a general shift from analogue experience of human life to a digital one. On the other hand, and in light of this shift, it seeks to re-evaluate our understanding of the fundamental values most crucial to the well-being of people, those taken for granted in a data-driven society and those most at risk. The objective of this report is thus not to generate definitive answers, nor to articulate new norms for present and future digital societies but to identify and describe the most crucial questions for the urgent conversation to come. This requires a conversation between legislators and data protection experts, but also society at large - because the issues identified in this report concern us all, not only as citizens but also as individuals. They concern us in our daily lives, whether at home or at work and there isn’t a place we could travel to where they would cease to concern us as members of the human species. (shrink)

Until recently, psychologists have conceptualised and studied trust in God (TIG) largely in isolation from contemporary work in theology, philosophy, history, and biblical studies that has examined the topic with increasing clarity. In this article, we first review the primary ways that psychologists have conceptualised and measured TIG. Then, we draw on conceptualizations of TIG outside the psychology of religion to provide a conceptual map for how TIG might be related to theorised predictors and outcomes. Finally, we provide a research (...) agenda for future empirical work in this area, as well as practical applications for counsellors and religious leaders. (shrink)

Peter van Inwagen famously offers a version of the luck objection to libertarianism called the ‘Rollback Argument.’ It involves a thought experiment in which God repeatedly rolls time backward to provide an agent with many opportunities to act in the same circumstance. Because the agent has the kind of freedom that affords her alternative possibilities at the moment of choice, she performs different actions in some of these opportunities. The upshot is that whichever action she performs in the actual-sequence (...) is intuitively a matter of mere chance. I explore a new response to the Rollback Argument. If there are true counterfactuals of libertarian freedom, then the agent performs the same action each time she is placed in the same circumstance, because that is what she would freely do in that circumstance. This response appears to negate the chancy intuition. Ultimately, however, I argue that this new response is unsuccessful, because there is a variant of the Rollback Argument that presents the same basic challenge to the libertarian on the assumption that there are true counterfactuals of libertarian freedom. Thus, true counterfactuals of libertarian freedom do not provide the libertarian with a solution to the Rollback Argument. (shrink)

Robert Audi’s Seeing, Knowing, and Doing argues that knowledge does not entail justification, given a broadly externalist conception of knowledge and an access internalist conception of justification, where justification requires the ability to cite one’s grounds or reasons. On this view, animals and small children can have knowledge while lacking justification. About cases like these and others, Audi concludes that knowledge does not entail justification. But the access internalist sense of “justification” is but one of at least two ordinary senses (...) of the term. On a broader or looser sense, “justification” means “being in the right” where that involves meeting a standard or norm. I argue that the beliefs of animals and small children can then meet standards or norms associated with truth and knowledge such that their beliefs may count as justified in this broader or looser sense. I then question whether knowledge fails to entail justification on this broader sense. (shrink)

Proper functionalism explicates epistemic warrant in terms of the function and normal functioning of the belief-forming process. There are two standard substantive views of the sources of functions in the literature in epistemology: God (intelligent design) or Mother Nature (evolution by natural selection). Both appear to confront the Swampman objection: couldn’t there be a mind with warranted beliefs neither designed by God nor the product of evolution by natural selection? Is there another substantive view that avoids the Swampman objection? There (...) are two. The first is the generalized selected-effects theory of functions. The second is the organizational theory of functions. Both, however, require some history to assign functions, for both are etiological theories of functions: past effects help explain current function. Swampman can then acquire functions, perhaps soon after creation, though he has none at the moment of inception. (shrink)

How should we undertand the role of norms—especially epistemic norms—governing assertive speech acts? Mitchell Green (2009) has argued that these norms play the role of handicaps in the technical sense from the animal signals literature. As handicaps, they then play a large role in explaining the reliability—and so the stability (the continued prevalence)—of assertive speech acts. But though norms of assertion conceived of as social norms do indeed play this stabilizing role, these norms are best understood as deterrents and not (...) as handicaps. This paper explains the stability problem for the maintenance of animal signals, and so human communication, for we are animals too, after all; the mechanics of the handicap principle; the role of deterrents and punishments as an alternative mechanism; and the role of social norms governing assertion for the case of human communication.

Epistemic defeat is standardly understood in either evidentialist or responsibilist terms. The seminal treatment of defeat is an evidentialist one, due to John Pollock, who famously distinguishes between undercutting and rebutting defeaters. More recently, an orthogonal distinction due to Jennifer Lackey has become widely endorsed, between so-called doxastic (or psychological) and normative defeaters. We think that neither doxastic nor normative defeaters, as Lackey understands them, exist. Both of Lackey’s categories of defeat derive from implausible assumptions about epistemic responsibility. Although Pollock’s (...) evidentialist view is superior, the evidentialism per se can be purged from it, leaving a general structure of defeat that can be incorporated in a reliabilist theory that is neither evidentialist nor responsibilist in any way. (shrink)

Our folk epistemology says that if someone knows that P and tells you that P, then, given the absence of defeaters, if you believe what they tell you, you will come to know that P as well. A speaker's knowledge that P is then, for the most part, enough for a hearer to come to know that P. But there are counterexamples to this principle: testimonial knowledge does not always transfer from the speaker to the hearer. Why should that be (...) so? Because testimonial knowledge arises through the flow of information--from conclusive grounds--from the speaker through the speaker's assertion to the hearer's state of comprehension as of the speaker's assertion. A speaker's belief can be based on conclusive grounds, but the speaker's assertion may fail to provide conclusive grounds to the hearer. Then the hearer won't acquire knowledge, even from a knowledgeable speaker. Knowledge from testimony then works more like knowledge through perception. But wait, you say, that can't be so because testimony involves free will but perception does not. The essay ends with a broadly Hume inspired reply to this objection. (shrink)

Social knowledge, for the most part, is knowledge through testimony. This essay is an overview of the epistemology of testimony. The essay separates knowledge from justification, characterizes testimony as a source of belief, explains why testimony is a source of knowledge, canvasses arguments for anti-reductionism and for reductionism in the reductionism vs. anti-reductionism debate, addresses counterexamples to knowledge transmission, defends a safe basis account of testimonial knowledge, and turns to social norms as a partial explanation for the reliability of testimony.

In 'Perceptual Entitlement' (PPR 2003), Tyler Burge argues that on his teleological reliabilist account of perceptual warrant, warrant will persist in non-normal conditions, even radical skeptical scenarios like demon worlds. This paper explains why Burge's explanation falls short. But if we distinguish two grades of warrant, we can explain, in proper functionalist, teleological reliabilist terms, why warrant should persist in demon worlds. A normally functioning belief-forming process confers warrant in all worlds, provided it is reliable in normal conditions when functioning (...) normally. The first grade requires normal functioning. The second grade also requires being situated in normal conditions. (shrink)

If you want to understand McDowell's spatial metaphors when he talks about perceptual knowledge, place him side-by-side with Dretske on perceptual knowledge. Though McDowell shows no evidence of reading Dretske's writings on knowledge from the late 1960s onwards (McDowell mentions "Epistemic Operators" once in passing), McDowell gives the same four arguments as Dretske for the conclusion that knowledge requires "conclusive" reasons that rule of the possibility of mistake. Despite various differences, we think it is best to read McDowell as re-discovering (...) Dretske on perceptual knowledge. Since Dretske is easy to understand, all of McDowell's metaphors become easy to understand. But what about McDowell's disjunctivism? Turns out McDowell is not an ontological disjunctivist, and his epistemological disjunctivism is really just the banal point that some perceptual experiences provide conclusive reasons for perceptual belief and some do not. Perceptual experiences are either conclusive or inconclusive. Dretske would agree. (shrink)

Alvin Plantinga argues by counterexample that no naturalistic account of functions is possible--God is then the only source for natural functions. This paper replies to Plantinga's examples and arguments. Plantinga misunderstands naturalistic accounts. Plantinga's mistakes flow from his assimilation of functional notions in general to functions from intentional design in particular.

Letter to the Editors in response to Alasdair Richmond's 'Time Travelers'.

Here are three (rough) theories of testimonial knowledge. (1) Speaker's knowledge: a hearer acquires the knowledge that P though testimony because of the speaker's knowledge that P--testimony "transfers" knowledge. This is the popular view, defended by Elizabeth Fricker and Paul Faulkner, among others. (2) Speaker's assertion: a hearer acquires the knowledge that P through testimony because the speaker's assertion that P is reliable that P in the right way (safe or sensitive). That's Jennifer Lackey's view. (3) Speaker's comprehension state: a (...) hearer acquired the knowledge that P through comprehending as of a speaker's assertion that P where the comprehension state is reliable in the right way (safe). That's my view. Lackey would reject such a view for it allows cases of testimonial knowledge that P from a speaker who did not assert that P. But Faulkner might reject Lackey's view on the grounds that it allows cases of testimonial knowledge that P from a speaker who did not know that P. Lackey replies that her account is better unified. But for the same reason, my account is even better unified. This paper runs through a series of cases and shows that my account--the Unified Account--is superior to the others. (shrink)

Jennifer Lackey ('Testimonial Knowledge and Transmission' The Philosophical Quarterly 1999) and Peter Graham ('Conveying Information, Synthese 2000, 'Transferring Knowledge' Nous 2000) offered counterexamples to show that a hearer can acquire knowledge that P from a speaker who asserts that P, but the speaker does not know that P. These examples suggest testimony can generate knowledge. The showpiece of Lackey's examples is the Schoolteacher case. This paper shows that Lackey's case does not undermine the orthodox view that testimony cannot generate (...) knowledge. This paper explains why Lackey's arguments to the contrary are ineffective for they misunderstand the intuitive rationale for the view that testimony cannot generate knowledge. This paper then elaborates on a version of the case from Graham's paper 'Conveying Information' (the Fossil case) that effectively shows that testimony can generate knowledge. This paper then provides a deeper informative explanation for how it is that testimony transfers knowledge, and why there should be cases where testimony generates knowledge. (shrink)

This paper argues for the general proper functionalist view that epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Such a process is reliable in normal conditions when functioning normally. This paper applies this view to so-called testimony-based beliefs. It argues that when a hearer forms a comprehension-based belief that P (a belief based on taking another to have asserted that P) through the exercise of a (...) reliable competence to comprehend and filter assertive speech acts, then the hearer's belief is prima facie warranted. The paper discusses the psychology of comprehension, the function of assertion, and the evolution of filtering mechanisms, especially coherence checking. (shrink)

Epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Evolution by natural selection is the most familiar source of etiological functions. . What then of learning? What then of Swampman? Though functions require history, natural selection is not the only source. Self-repair and trial-and-error learning are both sources. Warrant requires history, but not necessarily that much.

What is the biological function of perception? I hold perception, especially visual perception in humans, has the biological function of accurately representing the environment. Tyler Burge argues this cannot be so in Origins of Objectivity (Oxford, 2010), for accuracy is a semantical relationship and not, as such, a practical matter. Burge also provides a supporting example. I rebut the argument and the example. Accuracy is sometimes also a practical matter if accuracy partly explains how perception contributes to survival and reproduction.

Understanding recreational experiences is a longstanding research tradition and key to effective management. Given the complexities of human experience, many approaches have been applied to study recreational experience. Two such approaches are the experiential approach (based in a positivistic paradigm) and emergent experience (based in an interpretive paradigm). While viewed as being complementary, researchers have not offered guidance for incorporating the approaches into a common model of recreational experience. This study utilized longitudinal, qualitative data to examine aspects of recreational experience (...) posited by these two approaches. Results provided a framework for synthesizing across the two approaches. Respondents had clear pre-activity expectations, and most respondents realized their expected outcomes. This supports the experiential approach. Of the 48 activity narratives, 27 experienced something unexpected, and 45 described process-oriented, intrinsic motivation, suggesting evidence of emergent and unique characteristics specific to an individual’s realization of recreational experience. This supports the application of the emergent experience approach to understand how individuals create meaning from recreational engagements. The paper proposes a model for integrating results of the two approaches. While not advocating for any specific approach, the findings can serve as an example of building a holistic model of the outdoor recreation experience. The purpose of the model is to allow for a more complete understanding of how individuals create recreation experiences, more complete documentation of the benefits of outdoor recreation for both researchers and managers, and better synthesis across studies.

Does epistemic justification aim at truth? The vast majority of epistemologists instinctively answer 'Yes'; it's the textbook response. Joseph Cruz and John Pollock surprisingly say no. In 'The Chimerical Appeal of Epistemic Externalism' they argue that justification bears no interesting connection to truth; justification does not even aim at truth. 'Truth is not a very interesting part of our best understanding' of justification (C&P 2004, 137); it has no 'connection to the truth.' A 'truth-aimed ... epistemology is not entitled to (...) carry the day' (C&P 2004, 138, emphasis added).Pollock and Cruz's argument for this surprising conclusion is of general interest for it is 'out of step with a very common view on the ..

Noting minimal philosophical attention to the shift of the meanings of “genotype” and “phenotype,” and their distinction, as well as to the variety of meanings that have co-existed over the last hundred years, this note invites readers to join in exploring the implications of shifts that have been left unexamined.

This paper has grown out of concerns that I have about the way in which some pro-life arguments have been developing recently, and it is written in a spirit of frank dialogue with those whom I consider allies. I present three basic problems within some prominent contemporary pro-life argumentation, all three of which are rooted in a general tendency towards relying on empirical science in an increasingly exclusive way as the foundation of those arguments. The three problems that I touch (...) on are: a neglect of the role of God in human procreation, a neglect of the dignity of women, and a neglect of understanding personal being. (shrink)

Reliability theories of epistemic justification face three main objections: the generality problem, the demon-world (or brain-in-a-vat) counterexample, and the clairvoyant-powers counterexample. In Perception and Basic Beliefs(Oxford 2009), Jack Lyons defends reliabilism at length against the clairvoyant powers case. He argues that the problem arises due to a laxity about the category of basic beliefs, and the difference between inferential and non-inferential justification. Lyons argues reliabilists must pay more attention to architecture. I argue this isn’t necessarily so. What really matters for (...) understanding and solving the case involves paying closer attention to the origins of our belief forming capacities, both inferential and non-inferential. Reliabilists should make origins matter more. (shrink)

The standard taxonomy of theories of epistemic justification generates four positions from the Foundationalism v. Coherentism and Internalism v. Externalism disputes. I develop a new taxonomy driven by two other distinctions: Fundamentalism v. Non-Fundamentalism and Actual-Result v. Proper-Aim conceptions of epistemic justification. Actual-Result theorists hold that a belief is justified only if, as an actual matter of fact, it is held or formed in a way that makes it more likely than not to be true. Proper-Aim theorists hold that a (...) belief is justified only if it is held or formed in a way that it proper or correct insofar as truth is the aim or norm. Fundamentalists hold that which particular ways of holding or forming beliefs that confer justification is knowable a priori; epistemic principles are a priori necessary truths. Non- Fundamentalists disagree; epistemic principles are empirical contingent truths. The new taxonomy generates four positions: Cartesianism, Reliabilism, Intuitionism, and Pragmatism. The first two are Actual-Result; the second two are Proper-Aim. The first and third are Fundamentalist, the second and fourth are Non-Fundamentalist. The new taxonomy illuminates much of the current debate in the theory of epistemic justification. (shrink)

Reductionism about testimony holds that testimonial warrant or entitlement is just a species of inductive warrant. Anti-Reductionism holds that it is different from inductive but analogous to perceptual or memorial warrant. Perception receives much of its positive epistemic status from being reliably truthconducive in normal conditions. One reason to reject the epistemic analogy is that testimony involves agency – it goes through the will of the speaker – but perception does not. A speaker might always choose to lie or otherwise (...) deliberately mislead. It is argued that the force of this derives (in part) from Libertarianism about agency, and that Libertarianism, if it undermines the Anti-Reductionist explanation of why we are entitled to rely upon testimony, undermines the Reductionist explanation as..

Political liberals ask citizens not to appeal to certain considerations, including religious and philosophical convictions, in political deliberation. We argue that political liberals must include a demanding requirement of intellectual modesty in their ideal of citizenship in order to motivate this deliberative restraint. The requirement calls on each citizen to believe that the best reasoners disagree about the considerations that she is barred from appealing to. Along the way, we clarify how requirements of intellectual modesty relate to moral reasons for (...) deliberative restraint. And we argue against attempts to weaken our requirement of intellectual modesty by emphasizing those moral reasons. (shrink)

Climate engineering with stratospheric sulfate aerosol injections (SSAI) has the potential to reduce risks of injustice related to anthropogenic emissions of greenhouse gases. Relying on evidence from modeling studies, this paper makes the case that SSAI could have the potential to reduce many of the key physical risks of climate change identified by the Intergovernmental Panel on Climate Change. Such risks carry potential injustice because they are often imposed on low-emitters who do not benefit from climate change. Because SSAI has (...) the potential to reduce those risks, it thereby has the potential to reduce the injustice associated with anthropogenic emissions. While acknowledging important caveats, including uncertainty in modeling studies and the potential for SSAI to carry its own risks of injustice, the paper argues that there is a strong case for continued research into SSAI, especially if attention is paid to how it might be used to reduce emissions-driven injustice.

With The Birthright Lottery: Citizenship and Global Inequality, Ayelet Shachar is the first major scholar to put the rich theory of property law theory to work in the realm of citizenship. Assessed on its own criteria, the book delivers on its promise to shake up our thinking on this question. Nevertheless, I argue in this paper that her account is not ultimately persuasive. First, Shachar takes for granted that citizenship is a valuable resource. I suggest that today legal residency is (...) more highly valued that citizenship. Also her defense of the state and the social advantages of having stable citizenship regimes does nothing to confront its decline as the central organizing principle of political life. Last but not least, the modalities of a birthright citizenship levy calls into question the underlying analysis. For instance, the current proposal looks undistinguishable from foreign aid and it would demand much more robust institutional organs of global governance that now exist. The second prong of her argument works at the domestic level as it tackles the problem of under- and over-inclusiveness of birthright citizenship. Here too I have reservations highlighted by modes of implementation. (shrink)

Modern humans are probably a product of social and anatomical preadaptations on the part of our Miocene australopithecine ancestors combined with the increasingly high amplitude, high frequency climate variation of the Pleistocene. The genus Homo first appeared in the early Pleistocene as ice age climates began to grip the earth. We hypothesize that this co-occurrence is causal. The human ability to adapt by cultural means is, in theory, an adaptation to highly variable environments because cultural evolution can better track rapidly (...) changing environments than can genes. High resolution ice and sediment cores published in the early 1990s showed the last ice age was characterized by high amplitude millennial and submillenial scale variation, exactly the sort of variation mathematical models suggest should favor a costly capacity for culture. More recent cores suggest that over the last several 100 thousand year glacial cycles the amount of millennial scale variation has increased rather dramatically in parallel with increases in hominin brain size and sophistication of the artifacts they made.

Does ethics have adequate general theories? Our analysis shows that this question does not have a straightforward answer since the key terms are ambiguous. So we should not concentrate on the answer but on the question itself. “Ethics” stands for many things, but we let that pass. “Adequate” may refer to varied arrays of methodological principles which are seldom fully articulated in ethics. “General” is a notion with at least three meanings. Different kinds of generality may be at cross-purposes, so (...) we must not expect theories to be general in sundry senses. “Theory,” for that matter, is itself ambiguous. Some thinkers say that ethics cannot have theories, while others deny it. We doubt whether opposing parties are talking about the same things.No wonder, then, that controversies in ethics are long-lasting and unproductive. We hope that the methodology we have presented will alleviate some of them. The examples we chose show that this is feasible. Views such as Hare's and Jonsen and Toulmin's which are seemingly wide apart, show convergence if we put them in a methodological perspective.Our analysis also suggests that many alleged differences between science and ethics could fade away if methodology is brought to bear on them. Specifically, the idea that ethics compares poorly with science in view of limited generality, or poor means of justification, is unfounded. Those who defend this view over-rate the powers of science. (shrink)

Speakers offer testimony. They also hedge. This essay offers an account of how hedging makes a difference to testimony. Two components of testimony are considered: how testimony warrants a hearer's attitude, and how testimony changes a speaker's responsibilities. Starting with a norm-based approach to testimony where hearer's beliefs are prima facie warranted because of social norms and speakers acquire responsibility from these same norms, I argue that hedging alters both components simultaneously. It changes which attitudes a hearer is prima facie (...) warranted in forming in response to testimony, and reduces how much responsibility a speaker undertakes in testifying. A consequence of this account is that speakers who hedge for strategic purposes deprive their hearers of warrant for stronger doxastic attitudes. (shrink)

Worker well-being is a hot topic in organizations, consultancy and academia. However, too often, the buzz about worker well-being, enthusiasm for new programs to promote it and interest to research it, have not been accompanied by universal enthusiasm for scientific measurement. Aim to bridge this gap, we address three questions. To address the question ‘What is worker well-being?’, we explain that worker well-being is a multi-facetted concept and that it can be operationalized in a variety of constructs. We propose a (...) four-dimensional taxonomy of worker well-being constructs to illustrate the concept’s complexity and classify ten constructs within this taxonomy. To answer the question ‘How can worker well-being constructs be measured?’, we present two aspects of measures: measure obtrusiveness (i.e., the extent to which obtaining a measure interferes with workers’ experiences) and measure type (i.e., closed question survey, word, behavioral and physiological). We illustrate the diversity of measures across our taxonomy and uncover some hitherto under-appreciated avenues for measuring worker well-being. Finally, we address the question ‘How should a worker well-being measure be selected?’ by discussing conceptual, methodological, practical and ethical considerations when selecting a measure. We summarize these considerations in a short checklist. It is our hope that with this study researchers – working in organizations, in academia or both – will feel more competent to find effective strategies for the measurement worker well-being and eventually make policies and choices with a better understanding of what drives worker well-being.

Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

We present an investigation into the relation between design princi- ples in Japanese gardens, and their associated perceptual effects. This leads to the realization that a set of design principles described in a Japanese gardening text by Shingen (1466), shows many parallels to the visual effects of perceptual grouping, studied by the Gestalt school of psychology. Guidelines for composition of rock clusters closely relate to perception of visual figure. Garden design elements are arranged into patterns that simplify figure-ground segmentation, while (...) seemingly balancing the visual salience of subparts and the global arrangement. Visual ‘ground’ is analyzed via medial axis transformation (MAT), often associated with shape perception in humans. MAT analysis reveals implicit structure in the visual ground of a quintessential rock garden design. The MAT structure enables formal com- parison of structure of figure and ground. They share some aesthetic qualities, with interesting differences. Both contain naturalistic asymmetric, self-similar, branching structures. While the branching pattern of the ground converges towards the viewer, that of the figure converges in the opposite direction. (shrink)

Assertion is widely regarded as an act associated with an epistemic position. To assert is to represent oneself as occupying this position and/or to be required to occupy this position. Within this approach, the most common view is that assertion is strong: the associated position is knowledge or certainty. But recent challenges to this common view present new data that are argued to be better explained by assertion being weak. Old data widely taken to support assertion being strong has also (...) been challenged. This paper examines such challenges and finds them wanting. Far from diminishing the case for strong assertion, carefully considering new and old data reveals that assertion is as strong as ever. (shrink)

A speaker's use of a declarative sentence in a context has two effects: it expresses a proposition and represents the speaker as knowing that proposition. This essay is about how to explain the second effect. The standard explanation is act-based. A speaker is represented as knowing because their use of the declarative in a context tokens the act-type of assertion and assertions represent knowledge in what's asserted. I propose a semantic explanation on which declaratives covertly host a "know"-parenthetical. A speaker (...) is thereby represented as knowing the proposition expressed because that is the semantic contribution of the parenthetical. I call this view parentheticalism and defend that it better explains knowledge representation than alternatives. As a consequence of outperforming assertoric explanations, parentheticalism opens the door to eliminating the act-type of assertion from linguistic theorizing. (shrink)

Epistemic terms of various syntactic categories can uniformly be used to do the same thing—to hedge. This essay clarifies hedging as a phenomenon and explains how hedging happens by advancing the positional theory. The guiding idea is that, in uttering declaratives, speakers signal what their epistemic position is towards the content put into play by the declarative. The default signal is that the speaker knows. But when an epistemic term hedges, the term overrides the default. The non-default signal sent is (...) that the speaker or someone else occupies the position indicated by the term. To make that idea precise, the positional theory treats hedging as a discourse function. Terms hedge because of how a declarative containing an epistemic term is situated within a discourse.

A naturalistic theory of intentionality is proposed that differs from previous evolutionary and tracking theories. Full-blown intentionality is constructed through a series of evolvable refinements. A first, minimal version of intentionality originates from a conjectured internal process that estimates an organism’s own fitness and that continually modifies the organism. This process produces the directedness of intentionality. The internal estimator can be parsed into intentional components that point to components of the process that produces fitness. It is argued that such intentional (...) components can point to mistaken or non-existing entities. Different Fregian senses of the same reference correspond to different components that have different roles in the estimator. Intentional components that point to intentional components in other organisms produce directedness towards semi-abstract entities. Finally, adding a general, population-wide means of communication enables intentional components that point to fully abstract entities. Intentionality thus naturalized has all of its expected properties: being directed; potentially making errors; possibly pointing to non-existent, abstract, or rigid entities; capable of pointing many-to-one and one-to-many; distinguishing sense and reference; having perspective and grain; and having determinate content. Several examples, such as ‘swampman’ and ‘brain-in-a-vat’, illustrate how the theory can be applied. (shrink)
