According to the most common interpretation of the simulation argument, we are very likely to live in an ancestor simulation. It is interesting to ask if some families of simulations are more likely than others inside the space of all simulations. We argue that a natural probability measure is given by computational complexity: easier simulations are more likely to be run. Remarkably this allows us to extract experimental predictions from the fact that we live in a simulation. For instance we (...) show that it is very likely that humanity will not achieve interstellar travel and that humanity will not meet other intelligent species in the universe, in turn explaining the Fermi's Paradox. On the opposite side, experimental falsification of any of these predictions would constitute evidence against our reality being a simulation. (shrink)

Why is there something rather than nothing? About this storied question we challenge the commonly accepted main assumption: the existence of something. Starting from Nothing only, we explain how our perceived reality emerges as an illusory self-referential interpretation of Nothing and build a framework to give precise definitions to fundamental concepts such as existence, reality, nothingness and somethingness. We then explore the consequences of this framework and we discover an explanation for the existence of laws of physics in our illusory (...) reality. By aiming to describe reality starting with Nothing, we provide the first instance of an assumption-less theory. (shrink)

There are several key ingredients common to the various forms of model-based reasoning considered in this book. The term ‘model’ comprises both internal and external representations. The models are intended as interpretations of target physical systems, processes, phenomena, or situations and are retrieved or constructed on the basis of potentially satisfying salient constraints of the target domain. The book’s contributors are researchers active in the area of creative reasoning in science and technology.

This paper attempts a reconstruction of reason’s contribution to empirical truth in connection with Kant’s definition of truth as the agreement of cognition with its object. I argue that Kant’s treatment of truth in the Transcendental Analytic gets completed in the Appendix to the Transcendental Dialectic with an often neglected but compelling argument (what I shall call the Variety Argument). This argument postulates such a variety in the appearances as to undermine any attempt at formulating empirical truths. Crucially, I argue (...) that this variety does not depict an extreme-case scenario, but our own epistemic situation without reason. Reason completes Kant’s theory of truth by allowing the understanding (i.) to form empirical concepts and (ii.) approximate to empirical truth. (shrink)

Scientific models typically contain idealizations, or assumptions that are known not to be true. Philosophers have long questioned the nature of idealizations: Are they heuristic tools that will be abandoned? Or rather fictional representations of reality? And how can we reconcile them with realism about knowledge of nature? Immanuel Kant developed an account of scientific investigation that can inspire a new approach to the contemporary debate. Kant argued that scientific investigation is possible only if guided by ideal assumptions—what he calls (...) “regulative ideas”. These ideas are not true of objects of nature, and yet they are not heuristic tools or fictional represen- tations. They are necessary rules governing the construction and assessment of scientific explanations. In this paper, I suggest that some idealizations can be interpreted as having necessary regulative value and as being compatible with scientific realism. I first analyze the puzzle of the nature of idealization and present the main approaches to this topic in the literature. Second, I reconsider the puzzle vis-a-vis a restricted, Kantian definition of idealization and a novel characterization of the relation between idealization and truth. Finally, I discuss in detail an example of idealization (the Hardy-Weinberg equilibrium) along the suggested Kantian lines. (shrink)

In this paper, we embark on the complicated discussion about the nature of vice in Virtue Ethics through a twofold approach: first, by taking seriously the claim that virtues (and certain flavours of vices) are genuinely dispositional features possessed by agents, and secondly, by employing a pluralistic attitude borrowed from Battaly’s pluralism (2008). Through these lenses, we identify three varieties of viciousness: incontinence, indifference, and malevolence. The upshot is that the notion of vice is not as categorically homogeneous as that (...) of virtue: some states of viciousness consist in interference of present virtuous dispositions, or mimicking of absent vicious ones, whereas others can be considered genuine dispositions themselves. Furthermore, this set-up can provide an interesting, albeit highly idealized story as to how, through the interference in one’s environment, one gets acquainted with vice in various degrees. Finally, this approach can be illuminating vis-à-vis Virtue Ethics in general; e.g. we can employ it to discuss more productively Johnston’s (2003) objection to Hursthouse’s (1999) account of moral conduct.

In Part I of this paper, we identified and compared various schemes for trivalent truth conditions for indicative conditionals, most notably the proposals by de Finetti and Reichenbach on the one hand, and by Cooper and Cantwell on the other. Here we provide the proof theory for the resulting logics DF/TT and CC/TT, using tableau calculi and sequent calculi, and proving soundness and completeness results. Then we turn to the algebraic semantics, where both logics have substantive limitations: DF/TT allows for (...) algebraic completeness, but not for the construction of a canonical model, while CC/TT fails the construction of a Lindenbaum-Tarski algebra. With these results in mind, we draw up the balance and sketch future research projects. (shrink)

In this study, we explore the sincerity of the rhetorical tone of 664 annual letters to shareholders (CEO letters). Prior studies adopt Impression Management theory to predict that firms obfuscate failures and emphasize successes to unfairly enhance their image and maintain organizational legitimacy. Yuthas et al. (J Bus Ethics 41:141–157, 2002) challenged such a view, showing that firms reporting earnings surprises engage in ethical discourse with shareholders. We adopt the methodology of Yuthas et al. (J Bus Ethics 41:141–157, 2002) to (...) explore the association between firm performance and the rhetorical features of CEO letters in a large sample of Fortune 500 firms in the wake of the global economic crisis. In contrast to most prior research, we find that optimistic tone is congruent with both past and future performance. We conclude that under tough macroeconomic conditions, incentives to distort public information strategically are low. Rather, firms tend to engage in communicative action aimed at dialoguing with shareholders through sincere disclosure. However, in our conclusions, we warn about the impact of accounting and rhetorical manipulation on the congruence between optimistic tone and financial performance. (shrink)

This article analyses a sceptical challenge resulting from metaphysical approaches to the problem of the necessity of empirical laws of nature in Kant’s critical philosophy (what I shall call ‘essentialist’ readings). I argue that this challenge may jeopardize the purpose of empirical enquiry (and therefore the plausibility of essentialist readings), but that Kant has internal resources to address it in the Dialectic of the Critique of Pure Reason. I show that reading this problem through the lens of the Dialectic allows (...) us to reconcile the metaphysical question of necessitation of laws with a robust sense of empirical cognition.

A U-shaped curve in a cognitive-developmental trajectory refers to a three-step process: good performance followed by bad performance followed by good performance once again. U-shaped curves have been observed in a wide variety of cognitive-developmental and learning contexts. U-shaped learning seems to contradict the idea that learning is a monotonic, cumulative process and thus constitutes a challenge for competing theories of cognitive development and learning. U-shaped behavior in language learning (in particular in learning English past tense) has become a central (...) topic in the Cognitive Science debate about learning models. Antagonist models (e.g., connectionism versus nativism) are often judged on their ability of modeling or accounting for U-shaped behavior. The prior literature is mostly occupied with explaining how U-shaped behavior occurs. Instead, we are interested in the necessity of this kind of apparently inefficient strategy. We present and discuss a body of results in the abstract mathematical setting of (extensions of) Gold-style computational learning theory addressing a mathematically precise version of the following question: Are there learning tasks that require U-shaped behavior? All notions considered are learning in the limit from positive data. We present results about the necessity of U-shaped learning in classical models of learning as well as in models with bounds on the memory of the learner. The pattern emerges that, for parameterized, cognitively relevant learning criteria, beyond very few initial parameter values, U-shapes are necessary for full learning power! We discuss the possible relevance of the above results for the Cognitive Science debate about learning models as well as directions for future research. (shrink)

Many important concepts of the calculus are difficult to grasp, and they may appear epistemologically unjustified. For example, how does a real function appear in “small” neighborhoods of its points? How does it appear at infinity? Diagrams allow us to overcome the difficulty in constructing representations of mathematical critical situations and objects. For example, they actually reveal the behavior of a real function not “close to” a point but “in” the point. We are interested in our research in the diagrams (...) which play an optical role –microscopes and “microscopes within microscopes”, telescopes, windows, a mirror role, and an unveiling role. In this paper we describe some examples of optical diagrams as a particular kind of epistemic mediator able to perform the explanatory abductive task of providing a better understanding of the calculus, through a non-standard model of analysis. We also maintain they can be used in many other different epistemological and cognitive situations. (shrink)

The standard representation of the Central Dogma (CD) of Molecular Biology conspicuously ignores metabolism. However, both the metabolites and the biochemical fluxes behind any biological phenomenon are encrypted in the DNA sequence. Metabolism constrains and even changes the information flow when the DNA‐encoded instructions conflict with the homeostasis of the biochemical network. Inspection of adaptive virulence programs and emergence of xenobiotic‐biodegradation pathways in environmental bacteria suggest that their main evolutionary drive is the expansion of their metabolic networks towards new chemical (...) landscapes rather than perpetuation and spreading of their DNA sequences. Faulty enzymatic reactions on suboptimal substrates often produce reactive oxygen species (ROS), a process that fosters DNA diversification and ultimately couples catabolism of the new chemicals to growth. All this calls for a revision of the CD in which metabolism (rather than DNA) has the leading role. (shrink)

The complexity of cognitive emulation of human diagnostic reasoning is the major challenge in the implementation of computer-based programs for diagnostic advice in medicine. We here present an epistemological model of diagnosis with the ultimate goal of defining a high-level language for cognitive and computational primitives. The diagnostic task proceeds through three different phases: hypotheses generation, hypotheses testing and hypotheses closure. Hypotheses generation has the inferential form of abduction (from findings to hypotheses) constrained under the criterion of plausibility. Hypotheses testing (...) is achieved by a deductive inference (from generated hypotheses to expected findings), followed by an eliminative induction, constrained under the criterion of covering, which matches expected findings against patient''s findings to select the best explanation. Hypotheses closure is a deductive-inductive type of inference very similar to the inferences operating in hypotheses testing. In this case induction matches the consequences of the generated hypotheses against the patient''s characteristics or preferences under the criterion of utility. By using the language exploited in this epistemological model, it is possible to describe the cognitive tasks underlying the most influential knowledge-based diagnostic systems. (shrink)

More than a hundred years ago, the American philosopher C. S. Peirce suggested the idea of pragmatism as a logical criterion to analyze what words and concepts express through their practical meaning. Many words have been spent on creative processes and reasoning, especially in the case of scientific practices. In fact, philosophers have usually offered a number of ways of construing hypotheses generation, but all aim at demonstrating that the activity of generating hypotheses is paradoxical, illusory or obscure, and thus (...) not analyzable. The “computational turn” gave us a new way to understand creative processes in a strictly pragmatic sense. Artificial Intelligence and Cognitive Science tools allow us to test concepts and ideas previously conceived in abstract terms. It is in the perspective of these actual models that we find the central role of abduction in the explanation of creative reasoning in science. What I call theoretical abduction certainly illustrates much of what is important in abductive reasoning, especially the objective of selecting and creating a set of hypotheses that are able to dispense good explanations of data, but fails to account for many cases of explanation occurring in science or in everyday reasoning when the exploitation of the environment is crucial. The concept of manipulative abduction is devoted to capture the role of action in many interesting situations: action provides otherwise unavailable information that enables the agent to solve problems by starting and performing a suitable abductive process of generation or selection of hypotheses. Many external things, usually inert from the epistemological point of view, can be transformed into what I call epistemic mediators, which are illustrated in the last part of the paper. (shrink)

It is possible to prove a real link between Machiavelli's pessimisitic vision of man and Christian Tradition on sin only through the analysis of two literary Texts, the Capitolo dell'Ambizione and the Esortazione alla penitenza. The Essay offers an historical inquiry on the philosophical-theological background of the Florentine thinker, focusing his Christian inheritance and meanwhile his peculiar secularizing interpretation.

Using an experiment with corporate financial managers, we find that when red flags are present in the financial statements under their review, managers identify those red flags and, in turn, have greater concerns over earnings quality. In addition, when pressure to meet a financial target is high, managers are more concerned about earnings quality when red flags are present. We also document that when red flags are present, managers are more likely to report both internally to their CEO and, if (...) their concerns are not resolved internally, externally to their auditor. Pressure to meet a financial target increases the likelihood managers report internally, but decreases their likelihood of reporting externally when red flags are present. Additional analyses document reporting differences between CFOs and controllers, and examine the important roles that short-term personal costs, job tenure, and a non-accounting background play in the ethical dilemma managers face when deciding whether to report externally.

Automatic identification system is a vessel tracking system, which since 2004 has become a global tool for the detection and analysis of seagoing traffic. In this article, we look at how this technology, initially designed as a collision avoidance system, has recently become involved in debates concerning migration across the Mediterranean Sea. In particular, after having briefly discussed its emergence and characteristics, we examine how through different practices of appropriation AIS, and the data it generate, have been seized upon, both (...) to contest and to sustain the exclusionary nature of borders, and the mass dying of migrants at sea to which it leads. We do so by referring to forms of data activism we have contributed to in the frame of our Forensic Oceanography project as well as to situations in which AIS has been mobilized by xenophobic groups to demand even stronger exclusionary measures. At the same time, we point to the multiplicity of actors who participate in the politics of migration through AIS in unexpected ways. We conclude by highlighting the irreducible ambivalence of practices of appropriation and call for persistent attention to one’s own positioning within the global datascape constituted by AIS and other data.

How many notions of cause are there? The causality literature is witnessing a flourishing of pluralist positions. Here I focus on a recent debate on whether interpreting causality in terms of inferential relations commits one to semantic pluralism (Reiss 2011) or not (Williamson 2006). I argue that inferentialism is compatible with a ‘weak’ form of monism, where causality is envisaged as one, vague cluster concept. I offer two arguments for this, one for vagueness, one for uniqueness. Finally, I qualify in (...) what sense the resulting form of monism is ‘weak’.¿Cuántas nociones de causa hay? Hay un resurgir de posiciones pluralistas en la bibliografía sobre causalidad. Me ocuparé aquí de un debate reciente sobre si la interpretación de la causalidad en términos de relaciones inferenciales nos compromete con el pluralismo semántico (Reiss 2011) o no (Williamson 2006). Defiendo que el inferencialismo es compatible con una forma ’debil’ de monismo, donde la causalidad se presenta como un único concepto vago y de agrupación (cluster). Ofrezco para ello dos argumentos, uno sobre vaguedad y otro sobre unicidad. Finalmente, matizaré en qué sentido esta forma demonismo es ’débil’. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The World Of Desire:Lacan Between Evolutionary Biology and Psychoanalytic TheoryLorenzo Chiesa (bio)The primary aim of this paper is to analyse the biological foundations of Lacan's notion of desire as expounded in his first two Seminars (1953-1955). These works provide us with his most detailed discussion of the species-specific preconditions that allow Homo sapiens to speak and establish symbolic pacts among individuals. Despite its irreducibility to the domain of animal (...) instincts, human desire can only be adequately understood against the background of an evolutionary enquiry on the emergence of language, one that problematises both the implicit teleological assumptions of a certain Darwinism and the logical consistency of an investigation of origins. Drawing on organic and anatomical evidence endorsed by natural scientists as different as Stephen Jay Gould and Adolf Portmann, Lacan postulates a primordial biological discord between man and his environment, centred on premature birth and a subsequent disorder of the imagination, from which language and the Symbolic immanently arise.1 Desire is seen in this context as coextensive with what, especially in Seminar I, Lacan repeatedly refers to as "the world of the symbol," or "the symbolic world"—a crucial phrase, rich with philosophical implications, to which critics have not yet [End Page 200] paid sufficient attention.2 The most important point to be grasped here is that the symbolic order is a world in the sense that, in always presenting itself to man as a totality, a uni-verse, it compensates for the failure of a strictly 'natural' relationship between man as animal and his environment. Yet, in performing this function, the Symbolic also amounts to nothing other than 'human nature' tout-court.3 In other words, the Symbolic is an exceptional and to a certain extent autonomous pseudo-environment that must nevertheless be interpreted by means of biological concepts.4 For this reason, the very opposition between nature and culture is as such put into question and re-proposed at a different level.5Lacan's seminars and articles of the early to mid-1950s are usually read from the standpoint of the notions of 'empty' and 'full' speech in their relation to the Kojèvian dialectic of the recognition of desire. While not underestimating the importance of this first formulation of desire as desire of the other, I intend to dwell especially on its biological presuppositions, since Lacan will maintain them—often to the point of taking them for granted—even after abandoning the notions of 'empty' and 'full' speech. This will also enable me to show that the supposedly Hegelian Lacan of this period is already preoccupied with a materialist explanation of language and of human desire as desire for recognition, both of which are framed within the context of a virulent anti-teleological, anti-humanist, and anti-vitalist polemics.It is, however, paramount to pre-emptively specify that my new approach to Seminars I and II does not intend to deny the impasses of Lacan's early notion of desire as a desire for recognition, which I have thoroughly discussed in Subjectivity and Otherness.6 In brief, the problem with Lacan's appropriation of Kojève is that, at this stage, the mutual recognition of one's desire is identified with the subject's fully successful integration into the symbolic order. What is not sufficiently stressed in this way—yet not entirely overlooked—is the incompleteness of the latter, the fact that man's pseudo-environment presents itself as a totality only insofar as it is structurally not-all. The [End Page 201] elaboration of a meticulous theoretical distinction between need, demand, and desire carried out in Seminars IV and V, as well as a direct confrontation with the Real as the not-all of the Symbolic in Seminar VII, will later oblige Lacan to reconsider this harmonic view. By the early 1960s, full integration in the Symbolic will be explicitly regarded as impossible and the dialectic of desire will consequently be focused on the level of the subject's mapping of himself as falling onto the object of the repressed fantasy.IIAccording to Lacan, man is born prematurely, that is, with "foetalised traits,"7 which are especially...

This paper examines the email discursive practices of particular speakers of two different languages, namely Peninsular Spanish and British English. More specifically, our study focuses on (in)formality and (in)directness therein, for these lie at the heart of considerable scholarly debate regarding, respectively (i) the general stylistic drift towards orality and informality in technology-mediated communication, and (ii) the degree of communicative (in)directness - within broader politeness orientations - of speakers of different languages, specifically an orientation towards directness in Peninsular Spanish vis-à-vis (...) indirectness in British English. The aim of this paper is thus to investigate the role of (in)formality and (in)directness in email messages sent by members of two groups of undergraduate students to their university lecturers. To this end, a corpus of 100 impromptu emails was compiled and analysed. Results revealed complex, fluctuating patterns regarding levels of (in)formality and (in)directness that underlined cross-cultural variation in the way that different sociopragmatic principles found expression in a specific computer-mediated communicative situation.

The article examines Voltaire's hypochondriac obsession with death and illness, as can be seen in his Correspondence throughout his entire life. His death is described by his secretary Wagničre in Mémoires sur Voltaire and by Condorcet in Vie de Voltaire. Both of them talk of his belief in reason and deism. As regards Voltaire's attitude toward death in the last years of his life, he at times seems to play with the idea of death, as in his Épître ŕ Horace. (...) More often, he is questioning the philosophical meaning of death where the individual disappears and only the species survives. Voltaire values "philosophical death" and believes that philosophy can help us to accept life and death. (shrink)

En un trabajo nuestro anterior, después de haber procurado una exposición crítica de la doctrina ocamista del conocimiento desde el punto de vista de su contraposición entre ¿notitia intuitiva/notitia abstractiva¿, dejábamos pendientes dos aspectos de la máxima importancia e interés: Uno, referente a las fuentes conceptuales o presupuestos doctrinales de la doctrina ocamista al respecto; otro, respecto de las consecuencias implícitas en dicha doctrina. Lo primero, nos servirá para valorar adecuadamente esta doctrina explícita y ver sus fundamentos. Lo segundo, para (...) medir su importancia histórica y comprender sus resultados y su influencia en posiciones sistemáticas posteriores a Ockham, pero precontenidas ya de alguna manera en su horizonte conceptual. Lo primero, corresponde a lo que pudiéramos denominar ¿pre-textos¿ o presupuestos implícitos; lo segundo, podría denominarse como ¿pos-textos¿ o consecuencias doctrinales, igualmente implícitas. De acuerdo con la idea de que todo el que escribe o habla, dice no sólo lo que explícitamente expresa, sino también lo que presupone y lo que implica en sus asertos como consecuencias.

Our brains make up a series of signs and are engaged in making or manifesting or reacting to a series of signs: through this semiotic activity they are at the same time engaged in “being minds.” An important effect of this semiotic activity of brains is a continuous process of “externalization of the mind” that exhibits a new cognitive perspective on the mechanisms underlying the semiotic emergence of abductive processes of meaning formation. I consider this process of externalization interplay critical (...) in analyzing the relation between meaningful semiotic internal resources and devices and their dynamical interactions with the externalized semiotic materiality suitably stocked in the environment. The last part of the paper will describe some aspects of this interplay between external diagrammatization and internal recapitulation showing the specificity of their co-evolution. (shrink)
