This paper has three main sections. The first section provides a general characterisation of presentism, eternalism and growing blockism. It presents a pair of core, defining claims that jointly capture each of these three views. This makes clear the respects in which the different views agree, and the respects in which they disagree, about the nature of time. The second section takes these characterisations and considers whether we really do have three distinct views, or whether defenders of these views are (...) somehow talking past one another when they claim to disagree. The third section looks at the key objections to each view and considers some of the replies that can be made to those objections. The paper concludes by offering some thoughts about how future research might help us resolve the debate between defenders of these three views. (shrink)

The set of equations which use only one variable and hold in all representable relation algebras cannot be derived from any finite set of equations true in all representable relation algebras. Similar results hold for cylindric algebras and for logic with finitely many variables. The main tools are a construction of nonrepresentable one-generated relation algebras, a method for obtaining cylindric algebras from relation algebras, and the use of relation algebras in defining algebraic semantics for first-order logic.

The calculus of relations was created and developed in the second half of the nineteenth century by Augustus De Morgan, Charles Sanders Peirce, and Ernst Schröder. In 1940 Alfred Tarski proposed an axiomatization for a large part of the calculus of relations. In the next decade Tarski's axiomatization led to the creation of the theory of relation algebras, and was shown to be incomplete by Roger Lyndon's discovery of nonrepresentable relation algebras. This paper introduces the calculus of relations and the (...) theory of relation algebras through a review of these historical developments. (shrink)

It is possible to wholly exist at multiple spatial locations at the same time. At least, if time travel is possible and objects endure, then such must be the case. To accommodate this possibility requires the introduction of a spatial analog of either relativising properties to times—relativising properties to spatial locations—or of relativising the manner of instantiation to times—relativising the manner of instantiation to spatial locations. It has been suggested, however, that introducing irreducibly spatially relativised or spatially adverbialised properties presents (...) some difficulties for the endurantist. I will consider an objection according to which embracing such spatially relativised properties could lead us to reject mereology altogether in favour of a metaphysics according to which objects are wholly present at every space-time point at which they exist. I argue that although such a view is coherent, there are some good reasons to reject it. Moreover, I argue that the endurantist can introduce spatially relativised or adverbialised properties without conceding that objects lack spatial parts. Such a strategy has the additional advantage that it allows the endurantist not only to explain time travel, but also to reconcile our competing intuitions about cases of fission. (shrink)

Temporal non-dynamists hold that there is no temporal passage, but concede that many of us judge that it seems as though time passes. Phenomenal Illusionists suppose that things do seem this way, even though things are not this way. They attempt to explain how it is that we are subject to a pervasive phenomenal illusion. More recently, Cognitive Error Theorists have argued that our experiences do not seem that way; rather, we are subject to an error that leads us mistakenly (...) to believe that our experiences seem that way. Cognitive Error Theory is a relatively new view and little has been said to explain why we make such an error, or where, in the cognitive architecture, such an error might creep in. In this paper we remedy this by offering a number of hypotheses about the source of error. In so doing we aim to show that Cognitive Error Theory is a plausible competitor to Phenomenal Illusion Theory. (shrink)

In this paper, I argue that not only is metaphysical modal normativism an attractive view but that, as a matter of fact, many of us have, all along, been metaphysical modal normativists of a particular stripe. Namely, we have been the kinds of modal normativists, in the form of counterpart theorists, who are robust realists about possibility simpliciter. Having introduced modal normativism as Thomasson does in Norms and Necessity, I go on to recast it in somewhat different terms. With this (...) re-casting in place we can see that while the view offers a pleasingly deflationary account of metaphysical necessity and possibility it does so only against the backdrop of robust realism about possibility simpliciter. If that is right, then Lewis’ counterpart theory turns out to be a potent version of metaphysical modal normativism. So many of us have, all along, been metaphysical modal normativists, and so much the better for it. (shrink)

In this paper we provide a psychological explanation for ‘grounding observations’—observations that are thought to provide evidence that there exists a relation of ground. Our explanation does not appeal to the presence of any such relation. Instead, it appeals to certain evolved cognitive mechanisms, along with the traditional modal relations of supervenience, necessitation and entailment. We then consider what, if any, metaphysical conclusions we can draw from the obtaining of such an explanation, and, in particular, if it tells us anything (...) about whether we ought to posit a relation of ground.

I argue that two competing accounts of persistence, three and four dimensionalism, are in fact metaphysically equivalent. I begin by clearly defining three and four dimensionalism, and then I show that the two theories are intertranslatable and equally simple. Through consideration of a number of different cases where intuitions about persistence are contradictory, I then go on to show that both theories describe these cases in the same manner. Further consideration of some empirical issues arising from the theory of special (...) relativity lead me to conclude that the two theories are equally explanatory, and thus finally that they are metaphysically equivalent.

Conjecture (1) of [Ma83] is confirmed here by the following result: if $3 \leq \alpha < \omega$, then there is a finite relation algebra of dimension α, which is not a relation algebra of dimension α + 1. A logical consequence of this theorem is that for every finite α ≥ 3 there is a formula of the form $S \subseteq T$ (asserting that one binary relation is included in another), which is provable with α + 1 variables, but not (...) provable with only α variables (using a special sequent calculus designed for deducing properties of binary relations).

Recent work in personal identity has emphasized the importance of various conventions, or ‘person-directed practices’ in the determination of personal identity. An interesting question arises as to whether we should think that there are any entities that have, in some interesting sense, conventional identity conditions. We think that the best way to understand such work about practices and conventions is the strongest and most radical. If these considerations are correct, persons are, on our view, conventional constructs: they are in part (...) constituted by certain conventions. A person exists only if the relevant conventions exist. A person will be a conscious being of a certain kind combined with a set of conventions. Some of those conventions are encoded in the being itself, so requiring the conventions to exist is requiring the conscious being to be organized in a particular way. In most cases the conventions in question are settled. There is no dispute about what the conventions are, and thus no dispute about which events a person can survive. These are cases where we take the conventions so much for granted, that it is easy to forget that they are there, and that they are necessary constituents of persons. Sometimes though, conventions are not settled. Sometimes there is a dispute about what the conventions should be, and thus a dispute about what events a person can survive. These are the traditional puzzle cases of personal identity. That it appears that conventions play a part in determining persons’ persistence conditions only in these puzzle cases is explained by the fact that only in these cases are the conventions unsettled. Settled or not though, conventions are necessary constituents of persons. (shrink)

Metaphysics is supposed to tell us about the metaphysical nature of our world: under what conditions composition occurs; how objects persist through time; whether properties are universals or tropes. It is near orthodoxy that whichever of these sorts of metaphysical claims is true is necessarily true. This paper looks at the debate between that orthodox view and a recently emerging view that claims like these are contingent, by focusing on the metaphysical debate between monists and pluralists about concrete particulars. This (...) paper argues that we should be contingentists about monism and pluralism, and it defends contingentism against some necessitarian objections by offering an epistemology of contingent metaphysical claims.

Too often, identifying practices of silencing is a seemingly impossible exercise. Here I claim that attempting to give a conceptual reading of the epistemic violence present when silencing occurs can help distinguish the different ways members of oppressed groups are silenced with respect to testimony. I offer an account of epistemic violence as the failure, owing to pernicious ignorance, of hearers to meet the vulnerabilities of speakers in linguistic exchanges. Ultimately, I illustrate that by focusing on the ways in which (...) hearers fail to meet speaker dependency in a linguistic exchange, efforts can be made to demarcate the different types of silencing people face when attempting to testify from oppressed positions in society.

Many metaphysicians tell us that our world is one in which persisting objects are four-dimensionally extended in time, and persist by being partially present at each moment at which they exist. Many normative theorists tell us that at least some of our core normative practices are justified only if the relation that holds between a person at one time, and that person at another time, is the relation of strict identity. If these metaphysicians are right about the nature of our (...) world, and these normative theorists are right about what justifies our normative practices, then we should be error theorists about the justification of at least some of our core normative practices and in turn, arguably we should eliminate those practices for which justification is lacking. This paper offers a way of resolving the tension between these two views that does not lead into the grips of error theory. It is a way that is amenable to “exceptionists” about persons: those who think there is something special about persons and the first-person perspective; that personhood cannot be explained naturalistically, and the first-person perspective is naturalistically irreducible. The conclusion is thus a conditional: given that one is an exceptionist, an attractive way to resolve this tension is to embrace the view that persons are sui generis ontological kinds. (shrink)

Human beings are embedded in diverse social, cultural and political groups through which we make sense of our technologically mediated lived experience. This article seeks to reaffirm the postphenomenological subject as a primarily social subject. Critics maintain that the current postphenomenological framework does not adequately address the social, cultural and political context in which human-technology relations take place. In recent years, various additions to postphenomenology have been suggested in order to address this contextual deficit. In this article, I argue that (...) a return to the phenomenological roots of postphenomenology reveals underexamined analytical tools that allow for greater socio-cultural and political sensitivity. I take Don Ihde’s supposed macroperceptual and microperceptual divide as a point of departure in claiming that postphenomenology has too hastily turned away from the subject as primarily socially situated. I draw upon the phenomenological tradition, particularly the social phenomenology of Alfred Schutz, to develop a social postphenomenological approach. This approach is informed by the Schutzian notions of action, the stock of knowledge at hand and consociates. In the resulting account, the postphenomenological schema of _I—Technology—World_ is reconstrued as _We—Technology—World_. (shrink)

One argument for the moving spotlight theory is that it better explains certain aspects of our temporal phenomenology than does any static theory of time. Call this the argument from passage phenomenology. In this paper it is argued that insofar as moving spotlight theorists take this to be a sound argument they ought embrace a new version of the moving spotlight theory according to which the moving spotlight is a cresting wave of causal efficacy. On this view it is more (...) than just presentness that is temporary: a range of other fundamental properties are also temporary because presentness synchronically changes the fundamental properties that are instantiated in the present moment, from those instantiated when that moment is future, or past. On this view having experiences as of presentness co-varies with the presence of presentness, allowing the moving spotlight theorist to provide a compelling explanation for why we have the temporal phenomenology we do, and to explain how we can know that we are present by reflecting on the nature of said phenomenology.

Kristie Miller and James Norton present a new account of metaphysical explanation, not as a philosophical technicality but as a feature of everyday life. This is the notion that we all use in ordinary contexts when we give explanations of a certain sort: Miller and Norton build their account on investigation of these explanatory practices.

This paper presents the strongest version of a non-perdurantist four-dimensionalism: a theory according to which persisting objects are four-dimensionally extended in space-time, but not in virtue of having maximal temporal parts. The aims of considering such a view are twofold. First, to evaluate whether such an account could provide a plausible middle ground between the two main competitor accounts of persistence: three-dimensionalism and perdurantist four-dimensionalism. Second, to see what light such a theory sheds on the debate between these two competitor (...) theories. I conclude that despite prima facie reasons to suppose that non-perdurantist four-dimensionalism might be a credible alternative to either other account of persistence, ultimately the view is unsuccessful. The reasons for its failure illuminate the sometimes stagnant debate between three-dimensionalists and perdurantists, providing new reasons to prefer a perdurantist metaphysics. (shrink)

Endurantism is not inconsistent with the theory of special relativity, or so I shall argue. Endurantism is not committed to presentism, and thus not committed to a metaphysics that is at least prima facie inconsistent with special relativity. Nor is special relativity inconsistent with the idea that objects are wholly present at a time just if all of their parts co-exist at that time. For the endurantist notion of co-existence in terms of which “wholly present” is defined, is not, I (...) will argue, a notion according to which co-existence is transitive. Although an absence of absolute simultaneity presents some problems for the endurantist claim that objects are wholly present whenever they exist, there are a number of ways that the endurantist can respond to this difficulty. Thus, I conclude, considerations pertaining to the theory of special relativity certainly do not rule out endurantism as a metaphysics of persistence. (shrink)

Many think that sentences about what metaphysically explains what are true iff there exist grounding relations. This suggests that sceptics about grounding should be error theorists about metaphysical explanation. We think there is a better option: a theory of metaphysical explanation which offers truth conditions for claims about what metaphysically explains what that are not couched in terms of grounding relations, but are instead couched in terms of, inter alia, psychological facts. We do not argue that our account is superior (...) to grounding-based accounts. Rather, we offer it to those already ill-disposed towards grounding. (shrink)

This paper argues for a particular view about in what metaphysical equivalence consists: namely, that any two metaphysical theories are metaphysically equivalent if and only if those theories are strongly hyperintensionally equivalent. It is consistent with this characterisation that said theories are weakly hyperintensionally distinct, thus affording us the resources to model the content of propositional attitudes directed towards metaphysically equivalent theories in such a way that non-ideal agents can bear different propositional attitudes towards metaphysically equivalent theories.

We confirm a conjecture, about neat embeddings of cylindric algebras, made in 1969 by J. D. Monk, and a later conjecture by Maddux about relation algebras obtained from cylindric algebras. These results in algebraic logic have the following consequence for predicate logic: for every finite cardinal α ≥ 3 there is a logically valid sentence X, in a first-order language L with equality and exactly one nonlogical binary relation symbol E, such that X contains only 3 variables (each of (...) which may occur arbitrarily many times), X has a proof containing exactly α + 1 variables, but X has no proof containing only α variables. This solves a problem posed by Tarski and Givant in 1987. (shrink)

Kant's 'practical philosophy' comprehends a diverse group of his writings on ethics, politics, law, religion, and the philosophy of history and culture. Kristi E. Sweet demonstrates the unity and interdependence of these writings by showing how they take as their animating principle the human desire for what Kant calls the unconditioned - understood in the context of his practical thought as human freedom. She traces the relationship between this desire for freedom and the multiple forms of finitude that confront human (...) beings in different aspects of practical life, and stresses the interdependence of the pursuit of individual moral goodness and the formation of community through the state, religion, culture and history. This study of Kant's approach to practical life discovers that doing our duty, itself the realization of our individual freedom, requires that we set for ourselves and pursue a whole constellation of social, political and other communal ends.

Annual reports are an important element in the genre of corporate public discourse. The reporting practices mandated by the Securities and Exchange Commission for all publicly traded corporations are intended to render the annual reports a legitimate and trustworthy medium through which management communicates information related to the financial performance of the firm. The following discussion represents an inaugural attempt to investigate the ethical characteristics of the discourse found in corporate annual reports using Habermas' principles of communicative action. In preparing (...) the Management's Discussion and Analysis (MD&A) portion of the report, managers are charged with providing narrative information for investors and other interested third parties relevant to assessing the firm's financial condition. Previous rhetorical studies of the narrative portions of annual reports argue that they serve as means for both legitimate and distorted communication. We investigate this communication medium through the lens of Habermas' norms for communicative action, which require communicators to be comprehensible, truthful, sincere, and legitimate. The study represents an initial attempt to operationalization Habermas' principles of communicative action and to employ a methodology that facilitates their application to research within a business context. From one perspective, consistent with agency theory as specified by neoclassical economics, it would seem that firms anticipating worse-than-expected financial performance would be less likely to exhibit the Habermasian principles necessary for undistorted communication because they would attempt to strategically influence the message being communicated about the firm's financial position. Instead, employing rhetorical analysis software, Diction 5.0, we found that firms expecting both good and bad earnings surprises exhibited a higher level of communicative action than a composite average firm. Although preliminary in nature, our findings suggest that firms anticipating large earnings surprises, either high or low, use the narrative portion of the annual report as a vehicle through which to communicate information about managements' veracity and trustworthiness as well as the firm's financial position.

It was once held to be a virtue of the growing block theory that it combines temporal dynamism with a straightforward account of in virtue of what past-tensed propositions are true, and an explanation for why some future-tensed propositions are not true (assuming they are not). This put the growing block theory ahead of its principal dynamist rival: presentism. Recently, new growing block theorists have suggested that what makes true, past-tensed propositions, is not the same kind of thing as what (...) makes true, present-tensed propositions. They have done so in an attempt to defuse a particular epistemic objection to their view. In this paper it is argued that the new growing block theorist faces a dilemma. The more unified a strategy is for responding to the epistemic objection, the more that strategy results in the new growing block model positing truthmakers that are similar to those posited by the presentist, which erodes the purported advantage of the growing block theory over presentism. On the other hand, versions of the new growing block theory that embrace disunified strategies are better able to differentiate themselves from presentism, but are unattractive because of their disunity.

The concept of dignity is widely debated as to its efficacy as a ground upon which to base respect particularly in relation to human rights. Traditional concepts of inherent dignity associate dignity with the possession of rationality and autonomy, which consequently excludes non-rational humans from being viewed as possessing inherent dignity and therefore equal and inherent worth. This paper offers a theory of inherent dignity based on an account of a common humanity within which all humans might be seen as (...) possessing inherent worth and, therefore, deserving of being recognized and respected equally as ends in themselves. The theory is based on the communal practice and expectation of moral accountability, a practice that can be viewed as taking place universally both between and within human communities. (shrink)

In this paper I outline and defend a new approach to personal-identity—personal-identity non-cognitivism—and argue that it has several advantages over its cognitivist rivals. On this view utterances of personal-identity sentences express a non-cognitive attitude towards relevant person-stages. The resulting view offers a pleasingly nuanced picture of what we are doing when we utter such sentences.

In this paper, I argue that the thesis that time travel is logically possible, is inconsistent with the necessary truth of any of the usual ‘open futureobjective present’ models of the universe. It has been relatively uncontroversial until recently to hold that presentism is inconsistent with the possibility of time travel. I argue that recent arguments to the contrary do not show that presentism is consistent with time travel. Moreover, the necessary truth of other open future-objective present models which we (...) might, prima facie, have supposed to be more amenable to the possibility of time travel, turn out also to be inconsistent with this possibility.

Temporal dynamists typically hold that it seems to us as though time robustly passes, and that its seeming so is explained by the fact that time does robustly pass. Temporal non-dynamists hold that time does not robustly pass. Some non-dynamists nevertheless hold that it seems as though it does: we have an illusory phenomenal state whose content represents robust passage. Call these phenomenal passage illusionists. Other non-dynamists argue that the phenomenal state in question is veridical and represents something other than (...) robust passage. Call this the veridical passage-less view. This paper argues in favour of the latter view over the former, by arguing that we should reject passage illusionism. (shrink)

Digitalisation and emerging technologies affect our lives and are increasingly present in a growing number of fields. Ethical implications of the digitalisation process have therefore long been discussed by the scholars. The rapid development of artificial intelligence has taken the legal and ethical discussion to another level. There is no doubt that AI can have a positive impact on the society. The focus here, however, is on its more negative impact. This article will specifically consider how the law and ethics (...) in their interaction can be applied in a situation where a disabled person needs some kind of assistive technology to participate in the society as an equal member. This article intends to investigate whether the EU Guidelines for Trustworthy AI, as a milestone of ethics concerning technology, has the power to change the current practice of how social and economic rights are applied. The main focus of the article is the ethical requirements ‘Human agency and oversight’ and, more specifically, fundamental rights. (shrink)

It's not that we haven't always been here, since there was a here.

The value of tension is often underestimated. While it may be the case that tension causes destruction and harm, it is equally likely that it can open up new avenues for creation, adaption, and change. Tension can be used as a conceptual tool for thinking about the moments when bodies collide with time and space, and each makes its presence known. It is in tension that we see moments of opportunity arise. Body Tensions explores these moments through the use of (...) cross-chapter dialogue between inter-disciplinary and internationally located authors. Focusing on expressing and transgressing body tensions, the authors consider issues such as how humans embody time and space; where the limits of corporeality lie; and in what ways humans are able to re-imagine their bodies, environments, and cultures.

Here I outline an often under-appreciated position within Anglo-analytic epistemology, that of the apostate to operative metaphilosophical constraints. To help identify and promote awareness of metaphilosophical apostacy, here, I describe the form of metaphilosophical apostacy that I practice in Anglo-analytic epistemology (AAE). My apostasy with respect to AAE begins with significant, metaphilosophical divergences or deep senses of incongruence. A metaphilosophical divergence, on my account, refers to conflict at the level of inquiry-shaping assumptions, constraints, aims, and/or commitments. In this paper, I (...) claim that one way metaphilosophical apostasy emerges in Anglo-analytic epistemology is when inquiry-shaping divergences lead to conceptual indifference. Conceptual indifference, on my account, refers to disinterest that can follow from divergent metaphilosophical and/or aspirational aims and goals for one's favored investigations. To be clear, this is a paper for the growing population of epistemologists who find operative metaphilosophical constraints in AAE ill-fitting. (shrink)
