Digital duplicates reduce the scarcity of individuals and thus may impact their instrumental and intrinsic value. I here expand upon this idea by introducing the notion of collective scarcity, which pertains to the limitations faced by social groups in maintaining their size, cohesion, and function.

The problem of trickster leadership is discussed in this chapter in the context of the Romanian experience of modernity. This experience has emerged as a Post-Byzantine condition; it was strongly marked by the forty years of communist regimes and was loaded with a high amount of duplicity and ambivalence. The chapter argues that the communist type of trickster leadership in Romania was the outcome of a clash between two types of corruption: a domestic one and a global one. The idea (...) of ‘forms without substance’, coined in 1868 by the historian Titu Maiorescu, is shown to be indicative of the exilic condition in which Romanians remained caught even after their country became independent. The description of this paradoxical condition is followed by a review of the main eras of Romania as a modern state, arguing that this condition has led to an accumulation of disharmony and the absurd in the social fabric of the people.

Suppose that a physical duplicate of me, right down to the arrangements of subatomic particles, comes into existence at the time at which I finish this sentence. Suppose that it comes into existence by chance, or at least by a causal process entirely unconnected with me. It might be so situated that it, too, is seated in front of a computer, and finishes this paragraph and paper, or a corresponding one, just as I do. (i) Would it have the same (...) thoughts I do? (ii) Would it speak my language? (iii) Would my duplicate have any thoughts or (iv) speak any language at all? To fix the interpretation of these questions, I will take ‘thought’ to cover any mental state which has a representational content, where ‘representational content’ is intended to be neutral with respect to psychological mode. By 'psychological mode' I mean what distinguishes kinds of thoughts, such as belief, visual perceptual experience, desire, etc. Representational content, or thought content, as I will also say, determines the conditions under which a thought is true or false, veridical or non-veridical, or, more broadly, is satisfied or fails to be satisfied, independently of relativization to circumstances, possible worlds, or the like. Beliefs, desires, hopes, intentions, and perceptual experiences will all count as thoughts on this usage. The question whether one person has the same (type of) thought as another is the question whether both have a mental state with the same representational content in the same psychological mode. I will not count epistemic verbs, however, as picking out or expressing a (pure) psychological mode. Thus, although knowing that the time is ripe, seeing that there is a goldfinch in the garden, and remembering that my wife’s birthday is next Tuesday are all thoughts, they do not pick out the thoughts by using a verb that expresses a psychological mode. Therefore knowing, seeing or remembering the same things is not a requirement on having the same thoughts.. (shrink)

People commonly believe that any form of deception, no matter how innocuous it is and no matter whether the deceiving person intended it otherwise, is always morally wrong. In this paper, I will argue that deceiving in real-time is morally distinguishable from deceiving on-line because online actions aren’t as fine-grained as actions occurring in real-time. Our failure to detect the fine-grained characteristics of another avatar leads us to believe that that avatar intended to do a moral harm. Openly deceiving someone (...) on Facebook or Twitter is not a way to build wholesome virtual friendships but to destroy them. This paper will show how the traditional understanding of the doing / allowing distinction fails to apply in cyberspace. (shrink)

This article introduces the notion of duplex elements of the finite rings and corresponding neutrosophic rings. The authors establish duplex ring Dup(R) and neutrosophic duplex ring Dup(R)I)) by way of various illustrations. The tables of different duplicities are constructed to reveal the comparison between rings Dup(Zn), Dup(Dup(Zn)) and Dup(Dup(Dup(Zn ))) for the cyclic ring Zn . The proposed duplicity structures have several algebraic systems with dissimilar consequences. Author’s characterize finite rings with R + R is different from the duplex ring (...) Dup(R). However, this characterization supports that R + R = Dup(R) for some well known rings, namely zero rings and finite fields. (shrink)

In Against the Day, Pynchon is obsessed with twoness, double worlds, as well as dual realities, and like Deleuze’s concept of repetition, these duplications and twinships are not merely repetition of the same, rather they allow for creativity, reinvention, and becoming. Pynchon’s duplication of fictional and spectral characters intends to critique the notion of identity as does Deleuzian concept of repetition. Not attached to the representational concept of identity as the recurrence of the same, Pynchon’s duplications decenter the transcendental (...) concept in favor of a perpetual becoming and reproduces difference and singularity. Like Deleuze, Pynchon eschews an identity that is always guaranteed, and shows that the repetition of an object or a subject is not the recurrence of the original self-identical object or person. Moreover, Iceland spar, the mystifying calcite, with its doubling effect provides the reader with a view of a world beyond the ordinary, actual world, which is quite similar to what Pynchon’s novel does per se.

Physicalism is the view, roughly, that everything is physical. This thesis is often characterized in terms of a particular supervenience thesis. Central to this thesis is the idea of physical duplication. I argue that the standard way of understanding physical duplication leads—along with other claims—to a sub-optimal consequence for the physicalist. I block this consequence by shifting to an alternative sense of physical duplication. I then argue that physicalism is best characterized by a supervenience thesis that employs (...) both the new sense of physical duplication and a new class of possible worlds. (shrink)

Many of us share a strong intuition that fictional literature possesses cognitive value in the sense that it has the capacity to expand and/or clarify our knowledge or understanding of the world. If we agree that we learn something when we read and discuss certain texts, we may nevertheless find the form this learning takes to be anything but obvious.

A thought experiment demonstrates that physicalism about consciousness entails a para- doxical duplication of physical information. Moreover, objective existence acquires the status of a physical property. To avoid this paradox, one requires a concept of objectivity in which individuation is finite and incomplete. Finite individuation requires objective uncertainty and is thus corroborated by the contemporary sciences. Finite individuation and objective uncer- tainty prevent existence from becoming a physical property, thus defeating physicalism about consciousness and resolving the paradox.

Some influential arguments in the metaphysics of consciousness, in particular Chalmers’ Zombie Argument, suppose that all the physical properties of composed physical systems are metaphysically necessitated by their fundamental constituents. In this paper I argue against this thesis in order to debate Chalmers’ argument. By discussing, in non-technical terms, an EPR system I try to show that there are good reasons to hold that some composed physical systems have properties which are nomologically necessitated by their fundamental constituents, i.e., which emerge (...) in the sense of the so-called ‘nomological supervenience’ views.

The line connecting everything to everything is both diameter and circumference of a circle. Thus, complementarity is the basis for identity (duplicity is the basis for a unit). See, also, The Singularity and Object-Oriented Reality (also on PhilPapers).

In reply to the problem of evil, some suggest that God created an infinite number of universes—for example, that God created every universe that contains more good than evil. I offer two objections to these multiverse theodicies. First, I argue that, for any number of universes God creates, he could have created more, because he could have created duplicates of universes. Next, I argue that multiverse theodicies can’t adequately account for why God would create universes with pointless suffering, and hence (...) they don’t solve the problem of evil. (shrink)

Divers argued that there are modal truths that are inconvenient for the canonical Lewisian theory of modality. Noonan and Jago proposed an answer to the challenge, by invoking a duplicate interpretation of the modal truths. Here, I present a slightly different kind of modal truth that would prove inconvenient even for a Lewisian who accepts Noonan and Jago's proposal.

I explore the relationship between a prominent analysis of intrinsic properties, due to Langton and Lewis, and the phenomenon of quantum entanglement. As I argue, the analysis faces a puzzle. The full analysis classifies certain properties of entangled particles as intrinsic. But when combined with an extremely plausible assumption about duplication, the main part of the analysis classifies those properties as non-intrinsic instead. I conclude that much of Lewis’s metaphysics is in trouble: Lewis based many of his metaphysical views—his (...) thesis of Humean supervenience, for instance, and his account of recombination—on an analysis of intrinsicality which does not sit well with quantum phenomena.

Peter van Inwagen’s answer to the Special Composition Question, call it Organicism, says the xs compose y iff the activity of the xs constitutes a life. What about suspended lives (i.e., cryptobiosis)? Suppose a cat is alive at t1, completely frozen at t2, then revived at t3. Is the cat alive while frozen? Plausibly no, which according to Organicism means the cat-qua-composite ceases to exist at t2. Intuitively, however, the same cat seems present at all of t1, t2, and t3. (...) To account for these intuitions, van Inwagen modifies his answer: the xs compose y iff the activity of the xs constitutes or results from a life. Alas, this modification permits problematic duplication cases where one collection of objects composes something, yet a duplicate collection does not. This prompts the search for alternative modifications that identify frozen organisms as composites without introducing duplication problems. A dispositional variant is proposed. (shrink)

The neutral theory often is presented as a theory of "noise" or silent changes at an isolated "molecular level", relevant to marking the steady pace of divergence, but not to the origin of biological structure, function, or complexity. Nevertheless, precisely these issues can be addressed in neutral models, such as those elaborated here in regard to scrambled ciliate genes, gRNA-mediated RNA editing, the transition from self-splicing to spliceosomal splicing, and the retention of duplicate genes. All of these are instances of (...) a more general scheme of "constructive neutral evolution" that invokes biased variation, epistatic interactions, and excess capacities to account for a complex series of steps giving rise to novel structures or operations. The directional and constructive outcomes of these models are not due to neutral allele fixations per se, but to these other factors. Neutral models of this type may help to clarify the poorly understood role of non-selective factors in evolutionary innovation and directionality. (shrink)

Right-node raising of anaphors and bound pronouns out of coordinations, as in "Every student likes, and every professor hates, himself / his neighbors" is judged more acceptable in German and Dutch than in English. Using combinatory categorial grammar, this paper ties the cross-linguistic difference to the fact that German and Dutch are V-2 languages, and V-2 necessitates a lifted category for verbs that automatically caters to the right-node raised duplicator. The same lifted category is optionally available in English, but it (...) is not needed for independent syntactic purposes. (shrink)

In philosophy of mind, zombies are imaginary creatures that are exact physical duplicates of conscious subjects but for whom there is no first-personal experience. Zombies are meant to show that physicalism—the theory that the universe is made up entirely out of physical components—is false. In this paper, I apply the zombie thought experiment to the realm of morality to assess whether moral agency is something independent from sentience. Algorithms, I argue, are a kind of functional moral zombie, such that thinking (...) about the latter can help us better understand and regulate the former. I contend that the main reason why algorithms can be neither autonomous nor accountable is that they lack sentience. Moral zombies and algorithms are incoherent as moral agents because they lack the necessary moral understanding to be morally responsible. To understand what it means to inflict pain on someone, it is necessary to have experiential knowledge of pain. At most, for an algorithm that feels nothing, ‘values’ will be items on a list, possibly prioritised in a certain way according to a number that represents weightiness. But entities that do not feel cannot value, and beings that do not value cannot act for moral reasons. (shrink)

One's inaccuracy for a proposition is defined as the squared difference between the truth value (1 or 0) of the proposition and the credence (or subjective probability, or degree of belief) assigned to the proposition. One should have the epistemic goal of minimizing the expected inaccuracies of one's credences. We show that the method of minimizing expected inaccuracy can be used to solve certain probability problems involving information loss and self-locating beliefs (where a self-locating belief of a temporal part of (...) an individual is a belief about where or when that temporal part is located). We analyze the Sleeping Beauty problem, the duplication version of the Sleeping Beauty problem, and various related problems. (shrink)

When scientists seek further confirmation of their results, they often attempt to duplicate the results using diverse means. To the extent that they are successful in doing so, their results are said to be robust. This paper investigates the logic of such "robustness analysis" [RA]. The most important and challenging question an account of RA can answer is what sense of evidential diversity is involved in RAs. I argue that prevailing formal explications of such diversity are unsatisfactory. I propose a (...) unified, explanatory account of diversity in RAs. The resulting account is, I argue, truer to actual cases of RA in science; moreover, this account affords us a helpful, new foothold on the logic undergirding RAs. (shrink)

Several variants of Lewis's Best System Account of Lawhood have been proposed that avoid its commitment to perfectly natural properties. There has been little discussion of the relative merits of these proposals, and little discussion of how one might extend this strategy to provide natural property-free variants of Lewis's other accounts, such as his accounts of duplication, intrinsicality, causation, counterfactuals, and reference. We undertake these projects in this paper. We begin by providing a framework for classifying and assessing the (...) variants of the Best System Account. We then evaluate these proposals, and identify the most promising candidates. We go on to develop a proposal for systematically modifying Lewis's other accounts so that they, too, avoid commitment to perfectly natural properties. We conclude by briefly considering a different route one might take to developing natural property-free versions of Lewis's other accounts, drawing on recent work by Williams. (shrink)

It is possible that the world contains infinitely many agents that have positive and negative levels of well-being. Theories have been developed to ethically rank such worlds based on the well-being levels of the agents in those worlds or other qualitative properties of the worlds in question, such as the distribution of agents across spacetime. In this thesis I argue that such ethical rankings ought to be consistent with the Pareto principle, which says that if two worlds contain the same (...) agents and some agents are better off in the first world than they are in the second and no agents are worse off than they are in the second, then the first world is better than the second. I show that if we accept four axioms – the Pareto principle, transitivity, an axiom stating that populations of worlds can be permuted, and the claim that if the ‘at least as good as’ relation holds between two worlds then it holds between qualitative duplicates of this world pair – then we must conclude that there is ubiquitous incomparability between infinite worlds. I show that this is true even if the populations of infinite worlds are disjoint or overlapping, and that we cannot use any qualitative properties of world pairs to rank these worlds. Finally, I argue that this incomparability result generates puzzles for both consequentialist and non-consequentialist theories of objective and subjective permissibility. (shrink)

This article gives a Bayesian argument showing that, even if your total empirical evidence confirms that you have zillions of duplicate Boltzmann Brains, that evidence does not confirm that you are a Boltzmann Brain.

It is especially hard, at present, to read the newspapers without emitting a howl of anguish and outrage. Philosophy can heal some wounds but, in this case, political action may prove a better remedy than philosophy. It can therefore feel odd trying to think philosophically about surveillance at a time like this, rather than joining with like-minded people to protest the erosion of our civil liberties, the duplicity of our governments, and the failings in our political institutions - including our (...) political parties – revealed by the succession of leaks dripping away this the summer. Still, philosophy can help us to think about what we should do, not merely what we should believe. Thus, in what follows I draw on my previous work on privacy, democracy and security, in order to highlight aspects of recent events which – or so I hope – may prove useful both for political thought and action.

The replication crisis has caused researchers to distinguish between exact replications, which duplicate all aspects of a study that could potentially affect the results, and direct replications, which duplicate only those aspects of the study that are thought to be theoretically essential to reproduce the original effect. The replication crisis has also prompted researchers to think more carefully about the possibility of making Type I errors when rejecting null hypotheses. In this context, the present article considers the utility of two (...) types of Type I error probability: the Neyman–Pearson long run Type I error rate and the Fisherian sample-specific Type I error probability. It is argued that the Neyman–Pearson Type I error rate is inapplicable in social science because it refers to a long run of exact replications, and social science deals with irreversible units that make exact replications impossible. Instead, the Fisherian sample-specific Type I error probability is recommended as a more meaningful way to conceptualize false positive results in social science because it can be applied to each sample-specific decision about rejecting the same substantive null hypothesis in a series of direct replications. It is concluded that the replication crisis may be partly due to researchers’ unrealistic expectations about replicability based on their consideration of the Neyman–Pearson Type I error rate across a long run of exact replications.

Benardete paradoxes involve infinite collections of Grim Reapers, assassins, demons, deafening peals, or even sentences. These paradoxes have recently been used in arguments for finitist metaphysical theses such as temporal finitism, causal finitism, and discrete views of time. Here we develop a new finite Benardete-like paradox. We then use this paradox to defend a companions in guilt argument that challenges recent applications of patchwork principles on behalf of the aforementioned finitist arguments. Finally, we develop another problem for those applications by (...) examining the notion of exact duplication. (shrink)

I extend my direct virtue epistemology to explain how a knowledge-first framework can account for two kinds of positive epistemic standing, one tracked by externalists, who claim that the virtuous duplicate lacks justification, the other tracked by internalists, who claim that the virtuous duplicate has justification, and moreover that such justification is not enjoyed by the vicious duplicate. It also explains what these kinds of epistemic standing have to do with each other. I argue that all justified beliefs are good (...) candidates for knowledge, and are such because they are exercises of competences to know. However, there are two importantly different senses in which a belief may be a good candidate for knowledge, one corresponding to an externalist kind of justification and the other corresponding to an internalist one. I show how the account solves the new evil demon problem in a more satisfactory way than existing accounts. We end up with a view of knowledge, justification, and rationality that is plausible, motivated, and theoretically unified. (shrink)

In philosophical thought experiments, as in ordinary discourse, our understanding of verbal case descriptions is enriched by automatic comprehension inferences. Such inferences have us routinely infer what else is also true of the cases described. We consider how such routine inferences from polysemous words can generate zombie intuitions: intuitions that are ‘killed’ (defeated) by contextual information but kept cognitively alive by the psycholinguistic phenomenon of linguistic salience bias. Extending ‘evidentiary’ experimental philosophy, this paper examines whether the ‘zombie argument’ against materialism (...) is built on zombie intuitions. We examine the hypothesis that contextually defeated stereotypical inferences from the noun ‘zombie’ influence intuitions about ‘philosophical zombies’. We document framing effects (‘zombie’ vs ‘duplicate’) predicted by the hypothesis. Findings undermine intuitions about the conceivability of ‘philosophical zombies’ and address the philosophical ‘hard problem of consciousness’. Findings support a deflationary response: The impression that principled obstacles prevent scientific explanation of how physical processes give rise to conscious experience is generated by philosophical arguments that rely on epistemically deficient intuitions.

“There are no gaps in logical space,” David Lewis writes, giving voice to sentiment shared by many philosophers. But different natural ways of trying to make this sentiment precise turn out to conflict with one another.

Difference and Repetition: Deleuze’s magnum opus, “Difference and Repetition” (1968), explores the interplay between difference and repetition. He argues that difference is fundamental to reality, and repetition is not mere duplication but a creative force. Deleuze challenges conventional notions of identity and sameness, emphasizing the productive potential of difference. Gilles Deleuze’s “Difference and Repetition” is a seminal work that challenges traditional Western metaphysics and offers a fresh perspective on concepts like identity, repetition, and creativity. Let’s explore some key ideas (...) from this remarkable book: Pure Difference: Deleuze argues that difference is fundamental to reality. Unlike classical philosophy that seeks universal truths, he emphasizes divergence and decentering. Each moment contains unique differences, and these differences shape our understanding of the world. Complex Repetition: Repetition, for Deleuze, isn’t mere duplication. Instead, it involves displacement and disguising. While repetition contributes to generality and thought, it’s the differences within each repetition that account for change and novelty. Concepts and things derive meaning from these differences. Shift Away from Hegel and Marx: “Difference and Repetition” played a crucial role in shifting French thought away from Hegel and Marx toward Nietzsche and Freud. Deleuze’s exploration of difference challenged established philosophical norms and paved the way for new perspectives. The Image of Thought: Deleuze critiques the traditional “image of thought,” which often relies on fixed identities and binary oppositions. Instead, he encourages us to embrace multiplicities, complexities, and the perpetual process of becoming. Asymmetrical Synthesis of the Sensible: Deleuze introduces the concept of asymmetrical synthesis, emphasizing the interplay between perception and affect. Reality is a dynamic, ever-changing process, not a static being. Copies are never identical; they’re something new. “Difference and Repetition” invites us to rethink how we perceive reality, emphasizing creativity, multiplicity, and the constant flux of existence. Deleuze’s work continues to inspire thinkers across disciplines, bridging philosophy with art, literature, and mysticism. (shrink)

We provide a new perspective on the relation between the space of description of an object and the appearance of novelties. One of the aims of this perspective is to facilitate the interaction between mathematics and historical sciences. The definition of novelties is paradoxical: if one can define in advance the possibles, then they are not genuinely new. By analyzing the situation in set theory, we show that defining generic (i.e., shared) and specific (i.e., individual) properties of elements of a (...) set are radically different notions. As a result, generic and specific definitions of possibilities cannot be conflated. We argue that genuinely stating possibilities requires that their meaning has to be made explicit. For example, in physics, properties playing theoretical roles are generic; then, generic reasoning is sufficient to define possibilities. By contrast, in music, we argue that specific properties matter, and generic definitions become insufficient. Then, the notion of new possibilities becomes relevant and irreducible. In biology, among other examples, the generic definition of the space of DNA sequences is insufficient to state phenotypic possibilities even if we assume complete genetic determinism. The generic properties of this space are relevant for sequencing or DNA duplication, but they are inadequate to understand phenotypes. We develop a strong concept of biological novelties which justifies the notion of new possibilities and is more robust than the notion of changing description spaces. These biological novelties are not generic outcomes from an initial situation. They are specific and this specificity is associated with biological functions, that is to say, with a specific causal structure. Thus, we think that in contrast with physics, the concept of new possibilities is necessary for biology. (shrink)

The perfectly natural properties and relations are special—they are all and only those that "carve nature at its joints." They act as reference magnets, form a minimal supervenience base, figure in fundamental physics and in the laws of nature, and never divide duplicates within or between worlds. If the perfectly natural properties are the (metaphysically) important ones, we should expect being a perfectly natural property to itself be one of the (perfectly) natural properties. This paper argues that being a perfectly (...) natural property is not a very natural property, and examines the consequences. (shrink)

An intrinsic property, according to one important account, is a property that is had by all of one's duplicates. Instead, one might choose to characterize intrinsic properties as those that can be had in the absence of all distinct individuals.

The goal is to clarify the rough idea that an intrinsic property is a special sort of non-relational property; having the property does not consist in (...) any relation one bears to distinct individuals.

I develop the anticipatory argument for the view that it is nomologically possible that some non-biological creatures are phenomenally conscious, including conventional, silicon-based AI systems. This argument rests on the general idea that we should make our beliefs conform to the outcomes of an ideal scientific process and that such an ideal scientific process would attribute consciousness to some possible AI systems. This kind of ideal scientific process is an ideal application of the iterative natural kind (INK) strategy, according to (...) which one should investigate consciousness by treating it as a natural kind which iteratively explains observable patterns and correlations between potentially consciousness-relevant features. The relevant AI systems are psychological duplicates. These are hypothetical non-biological creatures which share the coarse-grained functional organization of humans. I argue that an ideal application of the INK strategy would attribute consciousness to psychological duplicates because this gives rise to a simpler and more unifying explanatory account of biological and non-biological cognition. If my argument is sound, then creatures made from the same material as conventional AI systems can be conscious, thus removing one of the main uncertainties for assessing AI consciousness and suggesting that AI consciousness may be a serious near-term concern.

This study presents a description of an open database on scientific output of Vietnamese researchers in social sciences and humanities, one that corrects for the shortcomings in current research publication databases such as data duplication, slow update, and a substantial cost of doing science. Here, using scientists’ self-reports, open online sources and cross-checking with Scopus database, we introduce a manual system and its semi-automated version of the database on the profiles of 657 Vietnamese researchers in social sciences and humanities (...) who have published in Scopus-indexed journals from 2008 to 2018. The final system also records 973 foreign co-authors, 1,289 papers, and 789 affiliations. The data collection method, highly applicable for other sources, could be replicated in other developing countries while its content be used in cross-section, multivariate, and network data analyses. The open database is expected to help Vietnam revamp its research capacity and meet the public demand for greater transparency in science management. (shrink)

It seems obvious that a community of one thousand scientists working together to make discoveries and solve puzzles should arrange itself differently than would one thousand scientist-hermits working independently. Because of limited time, resources, and attention, an independent scientist can explore only some of the possible approaches to a problem. Working alone, each hermit would explore the most promising approaches. They would needlessly duplicate the work of others and would be unlikely to develop approaches which look unpromising but really have (...) tremendous potential. Contrariwise, a large community can more rigorously explore the space of possible approaches. Most scientists should work on the most promising approaches, but a smaller number can be committed to approaches that initially look less promising. Exploratory work can reveal if one of those initially unpromising approaches has unrealized potential, and more scientists can adopt it once its potential becomes more apparent. (shrink)

This paper aims for a more robust epistemological disjunctivism (ED) by offering on its behalf a new and better response to the ‘new evil genius’ problem. The first section articulates the ‘new evil genius challenge’ (NEG challenge) to ED, specifying its two components: the ‘first-order’ and ‘diagnostic’ problems for ED. The first-order problem challenges proponents of ED to offer some explanation of the intuition behind the thought that your radically deceived duplicate is no less justified than you are for adopting (...) her perceptual beliefs. In the second section, I argue that 'blamelessness' explanations are inadequate to the task and offer better explanations in their place—that of ‘trait-level virtue’ and ‘reasonability’. The diagnostic problem challenges proponents of ED to explain why it is that classical internalists disagree with them about how to interpret 'new evil genius' considerations. The proponent of ED owes some error theory. I tackle this problem in the third section, arguing that classical internalists overlook disjunctivist interpretations of new evil genius intuitions owing to a mistaken commitment to a ‘vindicatory’ explanation of perceptual knowledge.

This paper deals with what I take to be one woman’s literary response to a philosophical problem. The woman is Jane Austen, the problem is the rationality of Hume’s ‘sensible knave’, and Austen’s response is to deepen the problem. Despite his enthusiasm for virtue, Hume reluctantly concedes in the EPM that injustice can be a rational strategy for ‘sensible knaves’, intelligent but selfish agents who feel no aversion towards thoughts of villainy or baseness. Austen agrees, but adds that ABSENT CONSIDERATIONS (...) OF A FUTURE STATE, other vices besides injustice can be rationally indulged with tolerable prospects of worldly happiness. Austen’s creation Mr Elliot in Persuasion is just such an agent – sensible and knavish but not technically ‘unjust’. Despite and partly because of his vices – ingratitude, avarice and duplicity – he manages to be both successful and reasonably happy. There are plenty of other reasonably happy knaves in Jane Austen, some of whom are not particularly sensible. This is not to say that either Austen or Hume is in favor of knavery It is just that they both think that only those with the right sensibility can be argued out of it. (shrink)

The Doctrine of Microphysical Supervenience states that microphysical duplicates cannot differ in their intrinsic properties. According to Merricks :59–71, 1998a, Objects and persons, Oxford University Press, 2001), however, this thesis is false, since microphysical duplicates can differ with respect to the intrinsic property of consciousness. In my view, Merricks’ argument is plausible, and extant attempts to reject it are problematic. However, the argument also threatens to make consciousness appear mysterious, by implying that consciousness facts fail to be microphysically determined and (...) that there can be brute and inexplicable differences in consciousness between material things. The paper therefore develops an account that can respect the soundness of Merricks’ argument while avoiding these problematic consequences. At the heart of the proposal is the idea that consciousness can be microphysically grounded despite failing to microphysical supervene. The proposed view also has the interesting consequence that consciousness is an intrinsic property despite depending on extrinsic factors for its instantiation. (shrink)

Representations are not only used in our folk-psychological explanations of behaviour, but are also fruitfully postulated, for example, in cognitive science. The mainstream view in cognitive science maintains that our mind is a representational system. This popular view requires an understanding of the nature of the entities they are postulating. Teleosemantic theories face this challenge, unpacking the normativity in the relation of representation by appealing to the teleological function of the representing state. It has been argued that, if intentionality is (...) to be explained in teleological terms, then the function of a state cannot depend on its phylogenetical history, given the metaphysical possibility of a duplicate of an intentional being that lacks an evolutionary history. In this paper, I present a method to produce, according to our current knowledge in genetic engineering, human-like individuals who are not the product of natural selection in the required sense. This variation will be used to shed light on the main replies that have been offered in the literature to the Swampman thought experiment. I argue that these replies are not satisfactory: representations should better not depend on natural selection. I conclude that a non-etiological notion of function is to be preferred for characterizing the relation of representation. (shrink)

Integrated Information Theory (IIT) identifies consciousness with having a maximum amount of integrated information. But a thing’s having the maximum amount of anything cannot be intrinsic to it, for that depends on how that thing compares to certain other things. IIT’s consciousness, then, is not intrinsic. A mereological argument elaborates this consequence: IIT implies that one physical system can be conscious while a physical duplicate of it is not conscious. Thus, by a common and reasonable conception of intrinsicality, IIT’s consciousness (...) is not intrinsic. It is then argued that to avoid the implication that consciousness is not intrinsic, IIT must abandon its Exclusion Postulate, which prohibits overlapping conscious systems. Indeed, theories of consciousness that attribute consciousness to physical systems, should embrace the view that some conscious systems overlap. A discussion of the admittedly counterintuitive nature of this solution, along with some medical and neuroscientific realities that would seem to support it, is included. (shrink)

McKitrick (2003) proposes that an object has a disposition if and only if there are a manifestation, the circumstances of the manifestation, a counterfactual true of the object, and an overtly dispositional locution referring to the disposition. A disposition is extrinsic if and only if an object has it, but a perfect duplicate of the object might not have it. I present an alternative definition that an object has a disposition if and only if a counterfactual is true of the (...) object that under a certain condition, it would interact with another object in a certain manner. There are three reasons for thinking that my definition is better than her definition. 1. Ockham’s razor favors my definition over McKitrick’s definition. My definition is consistent, while her definition is not, with Lewis’s and her definitions of intrinsic and extrinsic properties. 3. My definition goes well, while her definition does not, with our intuition that an object has a disposition even in a possible world where there is nothing but that object. (shrink)

Leading cosmological theories engender a controversial puzzle which has prompted philosophers to propose competing epistemological solutions and physicists to propose methodological changes to cosmology. The puzzle arises from the prediction that every brain on Earth will eventually be vastly outnumbered by physical duplicates formed by random collisions of particles in outer space. Supposing that this prediction is correct, shouldn't you believe that your brain is probably one of these vastly more typical extraterrestrial brains, since you cannot infer your brain's origin (...) from your experiential state? But supposing that your brain is one of these extraterrestrial brains, why be confident in the cosmological theories, since you never actually received testimony supporting these theories? Proposals in the literature either deny the rationality of believing theories that make the prediction or deny the typicality of your brain among its duplicates. This paper argues that these proposals are not entirely satisfactory. Instead, one should be confident in theories making the prediction on the supposition that your brain is one of the extraterrestrial brains. The upshots include that it may be rational to believe that your brain is probably an extraterrestrial brain and that cosmologists should not alter their methodology in response to the puzzle.

Questo articolo si confronta con la seguente domanda: possono le menti degli altri animali essere oggetti legittimi di apprezzamento estetico? Nel rispondere, sostengo (a) che la mente di altre specie animali è qualcosa che possiamo effettivamente apprezzare; (b) che oggetto dell’apprezzamento in questi casi è duplice: da un lato, apprezziamo l’idoneità alla funzione (fitness for function), le peculiarità, le differenze e le sottigliezze del funzionamento delle altre menti e, dall’altro, apprezziamo l’attività immaginativa attraverso la quale cerchiamo di metterci nella prospettiva (...) dell’altro animale; e (c) che, come conseguenza di (b), la natura del nostro apprezzamento è anch’essa duplice: da un lato, è un’esperienza delle qualità estetiche che emergono da ciò che sappiamo sul funzionamento delle altre menti e, dall’altro, traiamo piacere dallo sforzo immaginativo in cui ci impegniamo nel cercare di metterci nella prospettiva dell’altro animale.

Amie Thomasson’s Easy Ontology program is influential and attractive, but faces criticism for being too easy in a way that undercuts its realism by failing to recognize objects which don’t fall under known kinds and generating spurious and duplicative objects by mere conceptual engineering. We suggest that restricting the Easy Ontology program to artifacts avoids these difficulties. We also propose an Easy Ontology-inspired analysis of artifact which cuts through the major extant objections to existing analyses. As Thomasson suggests, our special (...) authorial role with regard to artifacts grants us privileged knowledge of them, which both disarms objections to Easy Ontology and allows a very easy ontology for artifacts. Easy Ontology and artifacts are made for each other. (shrink)

In a very general sense, hybrid can be understood to be any organism that is the product of two (or more) organisms where each parent belongs to a different kind. For example; the offspring from two or more parent organisms, each belonging to a separate species (or genera), is called a “hybrid”. “Hybridity” refers to the phenomenal character of being a hybrid. And “hybridization ” refers to both natural and artificial processes of generating hybrids. These processes include mechanisms of selective (...) cross-breeding and cross-fertilization of parents of different species for the purpose of producing hybrid offspring. In addition to these processes, “hybridization ” also refers to natural and artificial processes of whole genome duplication that result in the doubling or trebling of the sets of chromosomes of the organism. This entry provides an overview of the impact of hybridity on agriculture. It begins with an historical sketch that traces the early horticulturalists’ and naturalists’ investigations of hybrids. This starts with the observations of Thomas Fairchild and Georges-Louis Leclerc, Comte de Buffon; and leads to the explanation of its mechanism by Gregor Mendel, James Watson and Francis Crick, and Ernst Mayr; and the eventual manipulation of hybrids and hybridization by Barbara McClintock. Following this, the reader is introduced to a number of key terms and concepts in use within current research as well as highlighting diverse ethical concerns that center on hybridization. Recent research that attempts to ascertain the role of hybridization in adaptive change will be introduced. This will include research on the evolution of crop species, increased biodiversity, and the use of hybrids to manipulate phenotypically desirable traits in agricultural crops. The focus of the discussion is on a particularly significant type of naturally occurring hybridization, polyploidy hybridization. Polyploids are organisms which have more than two complete genomes in each cell. This kind of hybridization is ubiquitous among crop plants. The role of polyploidy in plant evolution and the affects of polyploidy on plants and animals will be reviewed. A critical discussion of its agricultural value in the production of fertile polyploid hybrids highlights key epistemological, ontological, and ethical issues. These are illuminated with reference to the distinct processes of artificial and natural hybridization. A survey of these different kinds of hybridization includes the ethical and economic impacts of hybridity on global nutrition, the environment, and considerations of some practical implications for the agricultural industry. Tracking the role of hybrids, the process of hybridization, and the current impacts of it for agriculture requires knowledge of the history of its early conceptualization, understanding, and use. This is the topic of the following section. (shrink)

It is widely held that the classic reassembly model of resurrection faces intractable problems. What happens to someone if God assembles two individuals at the resurrection which are equally good candidates for being the original person? If two or more people, such as a cannibal and the cannibal’s victim, were composed of the same particles at their respective deaths, can they both be resurrected? If they can, who gets the shared particles? And would an attempt to reassemble a long-gone individual (...) result in a genuine resurrection, or merely an intrinsic duplicate of the original person? In this paper, I argue that the first of these problems has, in effect, been solved by defenders of a rival view; I propose a novel solution to the second problem; and I show that the third can be solved by upgrading the naïve reassembly model to a novel variety of reassembly model.

Balancing a hermeneutic of trust with a hermeneutic of suspicion, this article develops a phenomenological description of imagination that highlights its alethic ambiguity. Imagination is an act of disclosure, without which the world of fiction and pure possibility cannot be constituted. Imagination is also an act of self-indulgence and narcissism, the source of much concealment and untruth. It is not the one or the other, but both at the same time, essentially ambiguous because of its phenomenological constitution. In this article, (...) I will take some steps towards clarifying this essential ambiguity of the imagination by drawing on the insights of Husserl and Sartre. Beginning with Husserl’s parallel treatment of imagination and perception as intuitive, objectifying acts, I will argue, drawing on insights from Sartre, that there is an important discrepancy between them with respect to the role of desire. While the constitution of perceptual presence is inseparable from a desire for truth, the desire involved in the constitution of imaginary presence has an ambiguous character, both epistemic and magical. This duplicity of desire partly accounts for the ambiguity of imagination, which is all the more pronounced the more the imagination demands the full emotional involvement of the imagining subject.

The Multiverse Response to the problem of evil has it that God made our universe because God makes every universe meeting a certain standard. The main problem for that response is that there’s no explanation for why God didn’t just keeping making duplicates of perfect universes. This paper introduces the ‘Multiactualities Response’, which says that God actualises every possible world that meets a certain standard of value. It avoids the corresponding problem about duplication because different propositions must always be (...) true at distinct worlds. The Multiactualities Response nevertheless has its own problem, namely that it requires the possibility of multiple actual worlds. This paper argues that if we consider spacetimes with wormholes, we have good cause to think there can be multiple metaphysically privileged present moments; given a suitable analogy between time and modality, it follows that there can be multiple metaphysically privileged (i.e. actual) worlds. This paper includes an in–depth examination of the metaphysics of both the temporal and modal cases. (shrink)
