The fourteen papers in this collection offer a variety of original contributions to the epistemology of modality. In seeking to explain how we might account for our knowledge of possibility and necessity, they raise some novel questions, develop some unfamiliar theoretical perspectives, and make some intriguing proposals. Collectively, they advance our understanding of the field. In Part I of this Introduction, I give some general background about the contemporary literature in the area, by sketching a timeline of the main tendencies (...) of the past twenty-five years or so, up to the present debates. Next, I focus on four features that largely characterize the latest literature, and the papers in the present collection in particular: (i) an endorsement of the importance of essentialism; (ii) a shift to a “metaphysics-first” approach to modal epistemology; (iii) a focus on metaphysical modality as opposed to other kinds of modality; and (iv) a preference for non-uniform modal epistemology. In Part II, I present the individual papers in the volume. These are organized around the following four chapters, based on their topic: (A) Skepticism & Deflationism; (B) Essentialism; (C) Non-Essentialist Accounts; (D) Applications. -/- LIST OF CONTRIBUTORS: Francesco Berto; Stephen Biggs & Jessica Wilson; Justin Clark-Doane; Philip Goff; Bob Hale; Frank Jackson; Mark Jago; Boris Kment; Antonella Mallozzi; Graham Priest; Gabriel Rabin; Amie Thomasson; Anand Vaidya & Michael Wallner; Jennifer Wang. -/- The volume is dedicated to the memory of Bob Hale. -/- .

In this chapter, I produce counterexamples to Presuppositional Epistemic Contextualism (PEC), a view about the semantics of ‘knowledge’-ascriptions that I have argued for elsewhere. According to PEC, the semantic content of the predicate ‘know’ at a context C is partly determined by the speakers’ pragmatic presuppositions at C. The problem for the view that I shall be concerned with here arises from the fact that pragmatic presuppositions are sometimes known to be true by the speakers who make them: hence the (...) Problem of Known Presuppositions. After discussing several unsuccessful ways to solve the problem, I propose the addition of a new Lewisian rule of proper ignoring to the semantics of PEC--namely, the Rule of Evidence-Based Ignoring. If the proposed account succeeds, the Problem of Known Presuppositions has a straightforward solution within the framework of PEC. (shrink)

Scholars, journalists, and activists working on climate change often distinguish between “individual” and “structural” approaches to decarbonization. The former concern choices individuals can make to reduce their “personal carbon footprint” (e.g., eating less meat). The latter concern changes to institutions, laws, and other social structures. These two approaches are often framed as oppositional, representing a mutually exclusive forced choice between alternative routes to decarbonization. After presenting representative samples of this oppositional framing of individual and structural approaches in environmental communication, we (...) identify four problems with oppositional thinking and propose five ways to conceive of individual and structural reform as symbiotic and interdependent.

Philosophy and Phenomenological Research, EarlyView.

Episodic memory (memories of the personal past) and prospecting the future (anticipating events) are often described as mental time travel (MTT). While most use this description metaphorically, we argue that episodic memory may allow for MTT in at least some robust sense. While episodic memory experiences may not allow us to literally travel through time, they do afford genuine awareness of past-perceived events. This is in contrast to an alternative view on which episodic memory experiences present past-perceived events as mere (...) intentional contents. Hence, episodic memory is a way of coming into experiential contact with, or being again aware of, what happened in the past. We argue that episodic memory experiences depend on a causal-informational link with the past events being remembered, and that, assuming direct realism about episodic memory experiences, this link suffices for genuine awareness. Since there is no such link in future prospection, a similar argument cannot be used to show that it also affords genuine awareness of future events. Constructivist views of memory might challenge the idea of memory as genuine awareness of remembered events. We explain how our view is consistent with both constructivist and anti-causalist conceptions of memory. There is still room for an interpretation of episodic memory as enabling genuine awareness of past events, even if it involves reconstruction. (shrink)

On the most popular account of material constitution, it is common for a material object to coincide precisely with one or more other material objects, ones that are composed of just the same matter but differ from it in sort. I argue that there is nothing that could ground the alleged difference in sort and that the account must be rejected.

For many years there has been a debate about the role of the parietal lobe in the generation of behavior. Does it generate movement plans (intention) or choose objects in the environment for further processing? To answer this, we focus on the lateral intraparietal area (LIP), an area that has been shown to play independent roles in target selection for saccades and the generation of visual attention. Based on results from a variety of tasks, we propose that LIP acts as (...) a priority map in which objects are represented by activity proportional to their behavioral priority. We present evidence to show that the priority map combines bottom-up inputs like a rapid visual response with an array of top-down signals like a saccade plan. The spatial location representing the peak of the map is used by the oculomotor system to target saccades and by the visual system to guide visual attention. (shrink)

This article articulates a framework for normatively assessing influence operations, undertaken by national security institutions. Section I categorizes the vast field of possible types of influence operations according to the communication’s content, its attribution, the rights of the target audience, the communication’s purpose, and its secondary effects. Section II populates these categories with historical examples and section III evaluates these cases with a moral framework. I argue that deceptive or manipulative communications directed at non-liable audiences are presumptively immoral and illegitimate (...) for liberal states, as are deceptive operations aimed at an unjust end, or even operations aimed at a just end where secondary effects are forecast to be disproportionate to the proximate end.

A central dispute in discussions of self-locating attitudes is whether attitude relations like believing and knowing are relations between an agent and properties (things that vary in truth value across individuals) or between an agent and propositions (things that do not so vary). Proponents of the proposition view have argued that the property view is unable to give an adequate account of relations like communication and agreement. We agree with this critique of the property view, and in this essay we (...) show that the problems facing the property view are much more serious than has been appreciated. We then develop and explore two versions of the proposition view. In each case, we show how facts about the self-ascription of properties may be determined by facts about propositional attitudes in conjunction with certain other facts. (shrink)

In this paper significant challenges are raised with respect to the view that explanation essentially involves unification. These objections are raised specifically with respect to the well-known versions of unificationism developed and defended by Michael Friedman and Philip Kitcher. The objections involve the explanatory regress argument and the concepts of reduction and scientific understanding. Essentially, the contention made here is that these versions of unificationism wrongly assume that reduction secures understanding.

In this paper, we explore how a conversational theory of moral responsibility can provide illuminating resources for building a theory about the nature and norms of moral forgiveness.

Philosophers debate whether all, some or none of the represcntational content of our sensory experience is conccptual, but the technical term "concept" has different uses. It is commonly linked more or less closely with the notions of judgdment and reasoning, but that leaves open the possibility that these terms share a systematic ambiguity or indeterminacy. Donald Davidson, however, holds an unequivocal and consistent, if paradoxical view that there are strictly speaking no psychological states with representational or intentional content except the (...) propositional attitudes of language users, since thc source or fundamental bearer of intentionality is the employed sentence. Accordingly he claims that what has content in ordinary sense experience is not sensation, but propositional belief caused, but not justified, by sensation. John McDowell, sharing some ofDavidson's premises,holds a less paradoxical, but (l will argue) equivocal and incoherent view that post-infantile human sensory expcrience must have content in so far as it is what grounds perceptual belief but that this content is itself conceptual or propositional, dependent on language and culture. Reasons are givcn in the present article for rejecting both views, and their common premises. It is argued that perceptual or sensory states have intentional content which is no more conceptual or propositional than the world is. Recognition that perceptual content and conceptual content are, in a certain unsurprising way incommensurable allows for a more realistic understanding of the relationship between Language and the world as we experience it.

To many, the idea of autonomous weapons systems (AWS) killing human beings is grotesque. Yet critics have had difficulty explaining why it should make a significant moral difference if a human combatant is killed by an AWS as opposed to being killed by a human combatant. The purpose of this paper is to explore the roots of various deontological concerns with AWS and to consider whether these concerns are distinct from any concerns that also apply to long- distance, human-guided weaponry. (...) We suggest that at least one major driver of the intuitive moral aversion to lethal AWS is that their use disrespects their human targets by violating the martial contract between human combatants. On our understanding of this doctrine, service personnel cede a right not to be directly targeted with lethal violence to other human agents alone. Artificial agents, of which AWS are one example, cannot understand the value of human life. A human combatant cannot transfer his privileges of targeting enemy combatants to a robot. Therefore, the human duty-holder who deploys AWS breaches the martial contract between human combatants and disrespects the targeted combatants. We consider whether this novel deontological objection to AWS forms the foundation of several other popular yet imperfect deontological objections to AWS. (shrink)

I develop a contractualist theory of just intelligence collection based on the collective moral responsibility to deliver security to a community and use the theory to justify certain kinds of signals interception. I also consider the rights of various intelligence targets like intelligence officers, service personnel, government employees, militants, and family members of all of these groups in order to consider how targets' waivers or forfeitures might create the moral space for just surveillance. Even people who are not doing anything (...) prejudicial to other states' security can be modeled as ceding rights against diagnostic collection--light touch collection limited to ascertaining if someone is likely an intelligence threat--as part of their duty to support just foreign institutions. Foreign intelligence officers could not perform the same job potential targets can reasonably demand their intelligence agencies perform on their behalf without this ceding of rights. More invasive forms of collection can only be justified if officers can reasonably model their citizens consenting to being the target of the same sort of collection by adversary states. (shrink)

I consider a puzzling case presented by Jose Benardete, and by appeal to this case develop a paradox involving counterfactual conditionals. I then show that this paradox may be leveraged to argue for certain non-obvious claims concerning the logic of counterfactuals.

In this paper, I consider how, given mutual knowledge of the information codified in a compositional semantic theory, an assertion of a sentence serves to update the shared information in a conversation. There is a standard account, due to Stalnaker, of how such conversational updating occurs. While this account has much to recommend it, in this paper I argue that it needs to be revised in light of certain patterns of updating that result from certain natural discourses. Having argued for (...) this, I present a new account of conversational updating that can be seen as a natural generalization of the standard account, and show how it can predict these patterns in a simple and principled manner.

The suite of secretive national security programs initiated in the US since 9/11 has created debate not only about the merits of targeted killing, torture, secret detention, cyberwar, global signals intercepts, and data-mining, but about the very secrecy in which these programs were conceived, debated by government officials, and implemented. Law must be revealed to those who are expected to comply with its demands. Law is a mere pretext for coercion if the laws permitting the government to coerce people for (...) non-compliance are concealed. The purpose of this essay is to determine whether inhabitants of a liberal state—a type of state tracing the legitimacy of its coercive actions to the consent of the governed—also need to know the internal protocols and legal findings of the government agencies ostensibly serving them. To put this question another way, what, if anything, may government agencies in liberal states keep secret? (shrink)

In this paper, I argue that some plausible principles concerning which credences are rationally permissible for agents given information about one another’s epistemic and credal states have some surprising consequences for which credences an agent ought to have in light of self-locating information. I provide a framework that allows us to state these constraints and draw out these consequences precisely. I then consider and assess the prospects for rejecting these prima facie plausible principles.

Suppose that five minutes ago, to our astonishment, a healthy, full-grown duck suddenly popped into existence on the table in front of us. Suppose further that there was no first time at which the duck existed but rather a last time, T, at which it had yet to exist. Then for each time t at which the duck has existed, there is an explanation of why the duck existed at t: there was a time t’ earlier than t but later (...) than T such that the duck existed at t’, and it was only to be expected that a healthy duck would survive the brief period from t’ to t. But would these explanations remove the mystery? Taken collectively, would they explain why the duck has existed since T rather than never having existed at all? Presumably not. But if not, this seems to discredit the style of explanation offered by Hume and Edwards for the infinite regress they hypothesize of causes and effects. (shrink)

The testimonia concerning weight in early Greek atomism appear to contradict one another. Some reports assert that the atoms do have weight, while others outright deny weight as a property of the atoms. A common solution to this apparent contradiction divides the testimonia into two groups. The first group describes the atoms within a κόσμος, where they have weight; the second group describes the atoms outside of a κόσμος, where they are weightless. A key testimonium for proponents of this solution (...) is Aëtius 1.3.18. It apparently denies weight as a property of the atoms, and supposedly describes the atoms when they are outside of a κόσμος. I argue against this interpretive solution by demonstrating, first, that Aëtius 1.3.18 does not deny that weight is a property of the atoms. Second, I argue that the report does not describe the atoms when they are outside of a κόσμος. Although these are largely negative conclusions, I contend that we are not left without a solution to the present interpretive difficulty. Once our testimonia concerning weight in early Greek atomism are examined thoroughly, it is clear that there is no conflict among them. (shrink)

Thirty years ago, I elaborated on a position that could be seen as a compromise between an "extreme," symbol-based AI, and a "neurochemical reductionism" in AI. The present article recalls aspects of the espoused framework of schema theory that, it suggested, could provide a better bridge from human psychology to brain theory than that offered by the symbol systems of A. Newell and H. A. Simon.

Levinas never engaged closely with Fichte’s work, but there are two places in the chapter “Substitution,” in Otherwise than Being (1974), where he mentions Fichte by name. The point that Levinas underscores in both of these passages is that the other’s encounter with the subject is not the outcome of the subject’s freedom; it is not posited by the subject, as Fichte has it, but is prior to any free activity. The aim of this paper is to deepen the comparison (...) between Levinas and Fichte, giving special attention to Fichte's own novel theory of intersubjectivity and the summons. One result that emerges from this treatment is that both Levinas and Fichte view the second person in a way that has no equivalent in the current philosophical landscape. On this reading, each thinker views responsibility to the other, not only as an immediate and particular obligation, but also as an asymmetrical relation that gives the other moral priority.

Aquinas’s analyses of akrasia can be divided into two: the discussions in his theological works and his Ethics commentary. The latter has sometimes been regarded as merely repetitive of Aristotle and unrepresentative of Aquinas’s own thoughts. As such, little attention has been paid to the specific, and sometimes significant, differences between the two treatments and to what those differences might mean. This paper remedies this situation by focusing on four such differences. I ultimately provide rationales for these differences, thereby arguing (...) for the consistency of the two treatments and the importance of consulting Aquinas’s Ethics commentary to gain a full appreciation of his view of akrasia. Using this strategy, the paper concludes with a controversial suggestion regarding the structure of the weak akratic’s reasoning. (shrink)

This chapter will develop standards for assessing individual moral responsibility for collective action. In some cases, these standards expand a person’s responsibility beyond what she or he would be responsible for if performing the same physical behavior outside of a group setting. I will argue that structural differences between two ideal types of groups— organizations and goal- oriented collectives— largely determine the baseline moral responsibility of group members for the group’s collective action. (Group members can be more or less responsible (...) for collective action beyond that baseline due to personal qualities like knowledge of the intended collective outcome.) The same individual physical behavior can make the member of a goal-oriented collective responsible for the entire collective action to an equal degree with her fellow group members, whereas the typical organization member is only responsible for his contributory action.

The article assesses different models of professional ethics and develops a model which sees professional imperatives as the institutionally-guided expression of foundational moral principles. This article uses the model to assess the moral pressures placed on interrogators in undercover operations in which a detective poses as a suspect in pre-arraignment holding. While highly effective, the level of empathetic rapport required risks incurring compassion fatigue and burn out on the part of detectives.

In Leviathan chapter 31 Hobbes refers to atheists and deists as "God's enemies." The contrast class is God's subjects in what he calls the Kingdom of God by Nature. This chapter offers an account of how one submits to God to become God's natural subject. The explanation reinforces the distinction between a primary and secondary state of nature. Submission to God obligates natural subjects to obey the laws of nature because the precepts of those laws acquire thereby the normative force (...) of law. The view further explains why submission to God differs from submission to a civil sovereign, despite the fact that both are voluntary. (shrink)

Relatively few authors attempt to assess individuals’ moral responsibility for collective action within organizations. I draw on fairly technical recent work by Seamus Miller, Christopher Kutz, and Tracy Isaacs in the field of collective responsibility to see what normative lessons can be prepared for people considering entry into large hierarchical, compartmentalized organizations like businesses or the military. I will defend a view shared by Isaacs that group members’ responsibility for collective action depends on intentions to contribute to particular collective actions, (...) against Miller and Kutz’s more inculpating standards. Miller and Kutz fail to achieve their goal of articulating a variable standard for measuring individual responsibility within organizations, for reasons suggesting we might not be able to do better with their theoretical commitments than a threshold warning for all potential entrants to be wary of the groups they enter. Isaacs sketches an approach that is more successful at creating a variable standard for assessing high echelon actors; I build on and refine her theory to argue that organization members can be held responsible for their unique interpretations of the organization mission and unique contributions to their role duties. High echelon actors may share personal responsibility for their subordinates’ behavior when they have created the conditions for those actions through their unique orders. (shrink)

This paper argues that Kant’s most famous objection to the ontological argument -- that existence is not a real predicate -- is not, in fact, his most effective objection, and that his ”neglected objection’ to the argument deserves to be better known. It shows that Kant clearly anticipates William Rowe’s later objection that the argument begs the question, and discusses why Kant himself seems to have overlooked the force of this criticism in his attempt to demolish the traditional proofs for (...) God’s existence. (shrink)

It is argued (a) that laws are assurances of protections of rights and (b) that governments are protectors of rights. Lest those assurances be empty and thus not really be assurances at all, laws must be enforced and governments must therefore have the power to coerce. For this reason, the government of a given region tends to have, as Max Weber put it, a "monopoly on power" in that region. And because governments are power-monopolizers, it is tempting to think that (...) the concepts of government and law are to be understood in terms of the concept of power. In actuality, the first two concepts are to be understood primarily in terms of the concept of morality--of rights-protection, to be specific--and only secondarily in terms of the concept of power. Contentions (a) and (b) appear to be inconsistent with obvious facts (e.g. the fact that Pol Pot's regime violated the rights of those over whom it had power). But (a) and (b) are compatible with those facts. This is a consequence of two principles. First, moral requirements have a "dimension of weight," as Dworkin put it, meaning that one moral imperative can be outweighed, without being obliterated, by another moral imperative. Second, sentential operators can have different degrees of scope. "It is hereby assured that" is such an operator. Linguistic surface structure may obfuscate the degree of scope that it has in a given sentence. That fact compatibilizes our analysis with the fact that there are evil laws and evil governments.

A brief overview of the Christian just war tradition, with case studies.

Introductory and advanced textbooks in bioethics focus almost entirely on issues that disproportionately affect disabled people and that centrally deal with becoming or being disabled. However, such textbooks typically omit critical philosophical reflection on disability, lack engagement with decades of empirical and theoretical scholarship spanning the social sciences and humanities in the multidisciplinary field of disability studies, and avoid serious consideration of the history of disability activism in shaping social, legal, political, and medical understandings of disability over the last fifty (...) years. For example, longstanding discussions on topics such as euthanasia, physician aid-in-dying, pre-implantation genetic diagnosis, prenatal testing, selective abortion, enhancement, patient autonomy, beneficence, non-maleficence, and health care rationing all tend to be premised on shared and implicit assumptions regarding disability, especially in relation to quality of life, yet with too little recognition of the way that “disability” is itself a topic of substantial research and scholarly disagreement across multiple fields. This is not merely a concern for academic and medical education; as an applied field tied to one of the largest economic sectors of most industrialized nations, bioethics has a direct impact on healthcare education, practice, policy, and, thereby, the health outcomes of existing and future populations. It is in light of these pressing issues that the Disability Bioethics Reader is the first reader to introduce students to core bioethical issues and concepts through the lens of critical disability studies and philosophy of disability. The Disability Bioethics Reader will include over thirty-five chapters covering key areas such as: critical histories and state-of-the-field analyses of modern medicine, bioethics, disability studies, and philosophy of medicine; methods in bioethics; concerns at the edge- and end-of-life; enhancement; disability, quality of life, and well-being; prenatal testing and abortion; invisible disabilities; chronic illness; healthcare justice; genetics and genomics; intellectual disability and neurodiversity; ethics and diagnosis; and epistemic injustice in healthcare.

Purpose: This study evaluates staff Training and Development Programmes (TDPs) in secondary schools based on the views of administrators and teachers. The research was implemented in public secondary schools in Cross River State, Nigeria. Design/Methodology/Approach: The study adopted the survey research design with 5408 participants (administrators = 542; teachers = 4595). Four research questions guided the study. The Staff Training and Development Programmes Questionnaire (STDPQ) was used for data collection. Findings revealed essential areas of staff training and development. Findings: Various (...) methods are employed for staff training and development. The results further showed various constraints that impeded staff TDPs in secondary schools. Conclusion: Based on the findings, it was concluded that staff in secondary schools have different training and development needs adjudged by both the principals and teachers as crucial for job enhancement. Various staff training and development methods can serve as valuable programmes to improve the current methods adopted. Research Limitations and Implications: There are various limitations in this study such as the small scope which may affect the extent to which generalizations can be made. It is suggested that future studies focus on expanding the scope to other regions and nations. Practical Implications: Despite the limitations, the study has made some advances to human capital and self-determination theories by providing findings. The findings of this study may direct the attention of curriculum planners, the government and school management to offer training and development opportunities based on the needs of teachers. Contribution to Literature: The study has contributed to the literature on staff training and development which can constitute a basis for further research in related areas. (shrink)

Proof by refutation of a geometry theorem that is not universally true produces a Gröbner basis whose elements, called side polynomials, may be used to give inequations that can be added to the hypotheses to give a valid theorem. We show that (in a certain sense) all possible subsidiary conditions are implied by those obtained from the basis; that what we call the kind of truth of the theorem may be derived from the basis; and that the side polynomials may (...) be classified in a useful way. We analyse the relationship between side polynomials and kinds of truth, and we give a unified algorithmic treatment of side polynomials, with examples generated by an implementation. (shrink)

Death has always been considered as an inevitable yet ‘’unpleasant’’ conclusion to one’s lifelong journey. While mainstream religions’ followers could at least remain optimistic about the afterlife possibilities for the atheists, death would always represent a total disappearance from the face of the universe beyond the point of no return. However, recent scientific advancements cloning and sell replacement have led many to believe that biological immortality is a reality rather than a dream. According to some of the leading futurists (e.g. (...) De Grey) turning back the human clock and achieving an indefinite lifespan is just a matter of time, so those of us who are going to last long enough to witness these amazing scientific breakthroughs may be rewarded with another 1000 years or so to enjoy.

Science is a crowning glory of the human spirit and its applications remain our best hope for social progress. However, there are limitations to existing science and perhaps to any science. The general mind-body problem is known to be currently intractable and mysterious (8). This is one of many deep problems that are generally agreed to be beyond the present purview of Science, including many quantum phenomena, etc. However, all of these famous unsolved problems are either remote from everyday experience (...) (entanglement, dark matter) or are hard to even define sharply (phenomenology, consciousness, etc.). In this note, we will consider some computational problems in vision that arise every time that we open our eyes and yet are demonstrably inconsistent with current theories of neural computation. The focus will be on two famous related phenomena, known as the neural binding problem and the experience of a detailed stable visual world. I, among many others, have struggled with these issues for more than fifty years (1, 2, 3). Somewhat paradoxically, the continuing progress in scientific methods and knowledge reveals that these are both unsolvable within existing neuroscience. By considering some basic facts about how the brain processes image input, we will show that, under the standard theory, there are not nearly enough brain neurons to compute what we experience as vision. Inconsistencies like the ones shown here have had a profound effect on paradigm change in the sciences. More directly, the discussions below suggest possible new theories and experiments. (shrink)

An interview with the American Philosophical Association regarding my work as an academic.

Different people reason differently, which means that sometimes they reach different conclusions from the same evidence. We maintain that this is not only natural, but rational. In this essay we explore the epistemology of that state of affairs. First we will canvass arguments for and against the claim that rational methods of reasoning must always reach the same conclusions from the same evidence. Then we will consider whether the acknowledgment that people have divergent rational reasoning methods should undermine one’s confidence (...) in one’s own reasoning. Finally we will explore how agents who employ distinct yet equally rational methods of reasoning should respond to interactions with the products of each others’ reasoning. We find that the epistemology of multiple reasoning methods has been misunderstood by a number of authors writing on epistemic permissiveness and peer disagreement. (shrink)

We might think that thought experiments are at their most powerful or most interesting when they produce new knowledge. This would be a mistake; thought experiments that seek understanding are just as powerful and interesting, and perhaps even more so. A growing number of epistemologists are emphasizing the importance of understanding for epistemology, arguing that it should supplant knowledge as the central notion. In this chapter, I bring the literature on understanding in epistemology to bear on explicating the different ways (...) that thought experiments increase three important kinds of understanding: explanatory, objectual and practical.

We discuss two leading theories of distributive justice: egalitarianism and prioritarianism. We argue that while each has particular merits and shortcomings, egalitarian views more fully satisfy a key requirement of distributive justice: respect for both the unity of the individual and the separateness of persons.

Ground offers the hope of vindicating and illuminating an classic philosophical idea: the layered conception, according to which reality is structured by relations of dependence, with physical phenomena on the bottom, upon which chemistry, then biology, and psychology reside. However, ground can only make good on this promise if it is appropriately formally behaved. The paradigm of good formal behavior can be found in the currently dominant grounding orthodoxy, which holds that ground is transitive, antisymmetric, irreflexive, and foundational. However, heretics (...) have recently challenged the orthodoxy. In this paper, I examine ground’s ability to vindicate the layered conception upon various relaxations of the orthodox assumptions. I argue that highly unorthodox views of ground can still vindicate the layered conception and that, in some ways, the heretical views enable ground to better serve as a guide to reality’s layering than do orthodox views of ground.

What role does the imagination play in scientific progress? After examining several studies in cognitive science, I argue that one thing the imagination does is help to increase scientific understanding, which is itself indispensable for scientific progress. Then, I sketch a transcendental justification of the role of imagination in this process.

This paper discusses Raimo Tuomela's we-mode account in his recent book "Social Ontology: Collective Intentionality and Group Agents" and develops the idea that mode should be thought of as representational. I argue that in any posture – intentional state or speech act – we do not merely represent a state of affairs as what we believe, or intend etc. – as the received view of 'propositional attitudes' has it –, but our position relative to that state of affairs and thus (...) ourselves. That is, we represent the subject through what I call "subject mode" and its position through what I call "position mode". I argue that the key to understanding collective intentionality is to understand how we represent others as co-subjects of positions rather than as their objects. This is shown on various levels of collective intentionality. On the non-conceptual level of joint attention we experience others as co-subjects who we attend with rather than to and who we are at least also disposed to act jointly with. On the conceptual level of the we-mode we represent others as co-subjects of positions of knowledge, intention, belief and shared values. Organizations and thus group agents in Tuomela's sense I propose to understand in terms of what I call "role mode", that is, in terms of the positions individuals and groups take as occupants of certain roles, for example, as committee members, or as chancellor of Germany. I try to show how this account, while very much in the spirit of Tuomela's, can avoid his fictionalism about group agents and some other problems of his account, while steering between the Scylla of excessive individualism and the Charybdis of extreme collectivism.
