Resumen La metáfora de la "descomposición" domina aún nuestra manera usual de pensar el análisis conceptual. Se trata de una herramienta muy útil para pensar este proceso tan abstracto, pero tiene limitaciones importantes. Por ejemplo, nos hace pensar que los componentes de un concepto deben estar en algún sentido contenidos en él o que la única manera en que dos conceptos pueden estar relacionados es que uno contenga al otro. Estas limitaciones no nos permiten dar cuenta de conceptos complejos cuya (...) estructura no es tan simple, como los de color o de medida. Por ello es tiempo de superar esta metáfora y pensar al análisis conceptual no sólo como descomposición, sino también como la asignación de diferentes funciones a los componentes de un concepto.Our customary way of thinking about conceptual analysis remains dominated by the metaphor of 'containment', which has certainly been very useful, but which also has important limitations. For example, it makes us think that the components of a concept must be, in some sense, contained in it or that the only way that two concepts can be related is if one contains the other. These limitations have not allowed us to account for concepts whose structure is not so simple, such as the concepts of color or measurement, among others. It is time, therefore, to overcome this metaphor and think of conceptual analysis not only as decomposition but also as the assignment of different functions to the components of a concept. (shrink)

Abstract In this essay, I will argue that images can play a substantial role in argumentation: exploiting information from the context, they can contribute directly and substantially to the communication of the propositions that play the roles of premises and conclusion. Furthermore, they can achieve this directly, i.e. without the need of verbalization. I will ground this claim by presenting and analyzing some arguments where images are essential to the argumentation process.

Luck (2009) argues that gamers face a dilemma when it comes to performing certain virtual acts. Most gamers regularly commit acts of virtual murder, and take these acts to be morally permissible. They are permissible because unlike real murder, no one is harmed in performing them; their only victims are computer-controlled characters, and such characters are not moral patients. What Luck points out is that this justification equally applies to virtual pedophelia, but gamers intuitively think that such acts are not (...) morally permissible. The result is a dilemma: either gamers must reject the intuition that virtual pedophelic acts are impermissible and so accept partaking in such acts, or they must reject the intuition that virtual murder acts are permissible, and so abstain from many (if not most) extant games. While the prevailing solution to this dilemma has been to try and find a morally relevant feature to distinguish the two cases, I argue that a different route should be pursued. It is neither the case that all acts of virtual murder are morally permissible, nor are all acts of virtual pedophelia impermissible. Our intuitions falter and produce this dilemma because they are not sensitive to the different contexts in which games present virtual acts. (shrink)

A natural starting point for theories of perceptual states is ordinary perception, in which a subject is successfully related to her mind-independent surroundings. Correspondingly, the simplest theory of perceptual states models all such states on perception. Typically, this simple, common-factor relational view of perceptual states has received a perfunctory dismissal on the grounds that hallucinations are nonperceptual. But I argue that the nonperceptual view of hallucinations has been accepted too quickly. I consider three observations thought to support the view, and (...) argue that all three are dealt with equally well by an alternative view, illusionism, on which hallucinations do involve perception. Since this is so, adopting a common-factor relational view of all perceptual states remains a tenable option. (shrink)

Alvin I. Goldman has argued that since one must count epistemic rules among the factors that help to fix the justificational status of agents (generally called J-factors), not all J-factors are internalist, that is, intrinsic to the agent whose justificational status they help to fix. After all, for an epistemic rule to count as a genuine J-factor, it must be objectively correct and, therefore, “independent of any and all minds.” Consequently, it cannot be intrinsic to any particular epistemic agent. In (...) this brief commentary, I will argue that Goldman’s argument misunderstands what it takes for epistemic justification to be internalist and, therefore, fails to guarantee his externalist conclusion. In particular, I want to demonstrate that Goldman’s argument trivializes the difference between intrinsic and extrinsic properties that lays at the basis of the internalist/externalist debate. I will show that, if sound, simple variations on Goldman’s argument could be used to prove the absurd conclusion that all properties are extrinsic. Now, since the intrinsic/extrinsic distinction is fundamental to debates in several areas of philosophy, not only the internalist/externalist debate in epistemology, I conclude that Goldman’s argument cannot be sound.

The science of logic has occupied an important role in Islamic history. Especially when al-Gazali 505-1111 has come and claimed that who learned Islamic sciences, without learning the Logic we cannot trust in his knowledge. From this time The science of logic has been flourished and quietly began to include in many sciences even Tefsir and Fiqh. After that, Al-razzi 606/1210 has established a big school in Islamic philosophy in general and in logic in particular. al-Khonaji 646/1248 one of his (...) important students. Who moved from Iran to Egypt and became Qadi al-Qudat (Chief Islamic justice). He has improved The science of logic by his books; like Keshf al-Asrar.

Beside that we have a lot of scholars has made commentaries on this book. In this article we focused on (Metn al-Jumal) by al-Konaji with his spreading in the Sixth. Seventh h.centuries. (shrink)

It is widely assumed that hallucinations are not a type of perception. Coupled with the idea that hallucinations possess phenomenal character, hallucinations raise a problem for naive realism, which maintains that phenomenal character is at least partly constituted by perceived worldly objects. While naive realists have typically responded by adopting a disjunctive view of phenomenal character, I argue that to resolve this conflict we should instead reject the idea that hallucinations are not a type of perception. I defend this view (...) by considering six alleged differences between hallucination and perception that are thought to support the idea that we do not perceive worldly objects when hallucinating. I argue that these differences are all accommodated for in a particular type of perception, picture perception. Drawing on picture perception's resources, I offer an account of hallucinations and their idiosyncrasies, in a way that is plausible in our world, that accounts for the variety of hallucination types, and that is compatible with naive realism.

In this paper I am concerned with an analysis of negative existential sentences that contain proper names only by using negative or neutral free logic. I will compare different versions of neutral free logic with the standard system of negative free logic (Burge, Sainsbury) and aim to defend my version of neutral free logic that I have labeled non-standard neutral free logic.

In this paper I aim to defend a first‐order non‐discriminating property view concerning existence. The version of this view that I prefer is based on negative (or a specific neutral) free logic that treats the existence predicate as first‐order logical predicate. I will provide reasons why such a view is more plausible than a second‐order discriminating property view concerning existence and I will also discuss four challenges for the proposed view and provide solutions to them.

In this paper I am concerned with the semantic analysis of sentences of the form 'It is true that p'. I will compare different proposals that have been made to analyse such sentences and will defend a view that treats this sentences as a mere sytactic variation of sentences of the form 'That p is true'.

This article asks the question “Why did Plato not write the ‘unwritten doctrine’?” and answers it by citing a combination of two obstacles. The first derives from the limitations of the episteme available to an embodied soul about the essence of the good. Even if the dialectician has access to some kind of knowledge, the mismatch between the unchanging essence of the good and the precarious logoi which aim to identify it (and allow others some measure of access to it) (...) can never fully be overcome. At best, Socrates (or Plato) can lead souls to an incomplete account of it: It is possible that even the most expert dialectician can only have a claim to knowledge, but no absolute certainty. Another obstacle lies in the audience or readership itself: No shortcut to understanding is possible, and yet a mere written presentation, which is all they have, is just such a shortcut, and so represents an empty promise. In memory of Charles H. Kahn (1928–2023), a letter of his from September 5, 1989, concerning the question “Why did Plato not write the ‘unwritten doctrine’?” is published, along with some comments.

In this paper I want to show that two proposals to determine Frege’s notion of a mark (Merkmal) of concepts that are made in the relevant literature face some serious interpretative and systematic problems. The main problem of both conceptions is that they cannot be properly applied to those explicit examples of complex concepts that are given in Frege’s works. The first of these conceptions interprets marks as analytic components of a concept, the second as defining parts of a concept. (...) I will show that only the second conception can be modified in a meaningful way such that we get a conception of marks as result that fits with Frege’s general characterizations and examples.

Drawing from empirical literature on ecological psychology, affective neuroscience, and philosophy of mind, this article describes a model of affect-as-motivation in the intentional bond between organism and environment. An epistemological justification for the motivating role of emotions is provided through articulating the perceptual context of emotions as embodied, situated, and functional, and positing perceptual salience as a biasing signal in an affordance competition model. The motivational role of affect is pragmatically integrated into discussions of action selection in the neurosciences.

A Revisão de Crenças estuda como agentes racionais mudam suas crenças ao receberem novas informações. O sistema AGM, trabalho mais influente desta área apresentado por Alchourrón, Gärdenfos e Makinson, postula critérios de racionalidade para os diferentes tipos de mudança de crenças e oferece construções explícitas para tais - a equivalência entre os postulados e operações é chamado de teroema da representação. Trabalhos recentes mostram como o paradigma AGM pode ser compatível com diferentes lógicas não-clássicas, o que é chamado de AGM-compatibilidade (...) - este é o caso da família de lógicas paraconsistentes que analisamos, as Lógicas da Inconsistência Formal (LFIs, da sigla em inglês). A despeito da AGM-compatibilidade, ao se partir de uma nova lógica sua racionalidade subjacente deve ser entendida e sua linguagem deve ser efetivamente usada. Propomos assim novas construções que de fato capturam a intuição presente na LFIs - é o que chamamos de sistema AGMo. Com isso, possibilitamos a estas lógicas uma nova interpretação, na esteira da epistemologia formal. Em uma abordagem alternativa, ao se partir da AGM-compatibilidade os resultados AGM podem ser diretamente aplicados às LFIs - o que chamamos de sistema AGMp. Em ambas abordagens, provamos os respectivos teoremas da representação sempre que necessário. (shrink)

Autonomy has been central to moral and political philosophy for millenia, and has been positioned as a critical aspect of both justice and wellbeing. Research in psychology supports this position, providing empirical evidence that autonomy is critical to motivation, personal growth and psychological wellness. Responsible AI will require an understanding of, and ability to effectively design for, human autonomy (rather than just machine autonomy) if it is to genuinely benefit humanity. Yet the effects on human autonomy of digital experiences are (...) neither straightforward nor consistent, and are complicated by commercial interests and tensions around compulsive overuse. This multi-layered reality requires an analysis that is itself multidimensional and that takes into account human experience at various levels of resolution. We borrow from HCI and psychological research to apply a model (“METUX”) that identifies six distinct spheres of technology experience. We demonstrate the value of the model for understanding human autonomy in a technology ethics context at multiple levels by applying it to the real-world case study of an AI-enhanced video recommender system. In the process we argue for the following three claims: 1) There are autonomy-related consequences to algorithms representing the interests of third parties, and they are not impartial and rational extensions of the self, as is often perceived; 2) Designing for autonomy is an ethical imperative critical to the future design of responsible AI; and 3) Autonomy-support must be analysed from at least six spheres of experience in order to approriately capture contradictory and downstream effects.

By Belief Revision it is understood a system that logically explains the rational process of changing beliefs by taking into account a new piece of information. The most influential approach in this field of study, the AGM system, proposed by Alchourrón, Gärdenfors, and Makinson, postulates rationality criteria for different types of belief change. In this paper I shall assess the relationship between those criteria and argue for an opposition between the principles of Information Economy and Consistency. Furthermore, I shall argue (...) that Paraconsistent Belief Revision manages to minimise this friction in the best possible way. (shrink)

En este texto retomo una pregunta importante que había quedado abierta al final del segundo capítulo de mi (2019): ¿cuáles son los límites del análisis? Sabemos que por obvias limitaciones materiales, todo análisis siempre será incompleto y por lo tanto, limitado. A estos límites les hemos llamado “metodológicos”, para distinguirlos de los metafísicos. Si el análisis tiene límites en este segundo sentido, aun si termináramos de analizar por completo un concepto, no podremos estar seguros de conocer todas sus propiedades esenciales (...) (ya que hay propiedades de este tipo que no las capta ningún análisis) o de ser capaces de distinguirlo de todos los conceptos (pues lo que lo distingue de otros conceptos puede ser inanalizable). Comúnmente se dice que el análisis no nos da todo el contenido de los conceptos, sino sólo su forma lógica o estructura semántica. Por lo tanto, otra manera de reformular la pregunta por los límites del análisis es ¿cuál es la relación entre forma y contenido? (shrink)

After the publication of Marshall’s theorem (2009), it has been widely accepted that the intrinsic/extrinsic distinction cannot be analyzed in broadly logical terms, but instead requires appealing to more robust metaphysical notions like grounding, naturalness or duplication. However, in this article I will defend that this is not so. Instead of showing the limitations of Marshall’s undoubtedly impressive result, I will present here a broadly logical definition of the intrinsic/extrinsic distinction, and show that it is extensional adequate regardless of our (...) preferred conception of property identity.

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the introduction of (...) space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)

A good metaphysical account of logical form, must make clear why logical form is logical. However, this task has proved to be very elusive. Here, I analyze different attempts to meet this challenge and defend an inferential externalism where logical form is grounded on external logical relations as our most promising option.

What is an inference and when is an inference deductive rather than inductive, abductive, etc. The goal of this paper is precisely to determine what is that we, humans, do when we engage in deduction, i.e., whether there is something that satisfies both our pre-theoretical intuitions and theoretical presuppositions about deduction, as a cognitive process. The paper is structured in two parts: the first one deals with the issue of what is an inference. There, I will defend the hypothesis that (...) an inference is a causal process where an initial cognitive state causes another in such a way that the causal translation depends essentially on the content of the involved states. In other words, in an inference, a mental state A causes another B, partially because they have the content they have. Based on the conclusion from the first part, I will develop an account of deductive inference in the second part of the article. In order to achieve this, I will start by setting the stage and developing four constraints that an adequate account of deductive inference ought to satisfy. Then, I will present six different hypotheses that one might propose to characterize inferences of this kind. I have divided the proposals in two groups, the first one – which I will call the “logical proposals” – assume that whether an inference is a deduction or not depends exclusively on the content of the mental states involved in the inference, while the second – which I will call the “cognitive proposals” – reject the aforementioned assumption and instead recognize that extra cognitive information is required to determine whether an inference is a deduction or not. I will evaluate each proposal in turn, according to whether they satisfy the constraints introduced at the beginning of this second part. As a result of such evaluation, I will conclude that only one of the cognitive proposals actually satisfies the four constraints and therefore should be considered to give an adequate characterization of deductive inference.

"Paraconsistent Belief Revision Based on a Formal Consistency Operator" delves into Belief Revision—a significant area of research in Formal Philosophy that uses logic to model the ways in which human and artificial agents modify their beliefs in response to new information and examines how these changes can be considered rational. -/- Originally authored as a PhD thesis (previously published in Portuguese), this work provides a novel epistemic interpretation of Paraconsistency through Paraconsistent Belief Revision systems. It explores the concept of paraconsistency (...) from the standpoint of epistemic attitudes of acceptance and rejection. -/- This work challenges the traditional notion that accepting a new belief requires retracting its negation from the current epistemic state. The author contends that such reflexive retraction goes against the principle of informational economy, which is a crucial aspect of rationality in the context of belief change. Consequently, the phenomenon of paraconsistency is further examined from this fresh perspective of belief change, shedding light on the complexities of the Logics of Formal Inconsistency (LFIs). These LFIs provide the foundational logic, offering a comprehensive framework for understanding and implementing paraconsistent principles within belief revision systems. -/- This thesis was supervised by Marcelo Esteban Coniglio and co-supervised by Márcio Moretto Ribeiro, as part of Rafael Rodrigues Testa's doctoral studies at the University of Campinas (Unicamp), Brazil.

Despite being very common in both public and private argumentation, accusations of selective application of general premises, also known as “whataboutisms”, have been mostly overlooked in argumentation studies, where they are, at most, taken as accusations of inconsistency. Here I will defend an account according to which allegations of this sort can express the suspicion that the argumentation put forward by one party does not reflect his or her actual standpoint and reasons. Distinguishing this kind of argumentative moves is important (...) for evaluating its appropriateness in critical discussions where knowing the honest opinion of arguers is relevant, as in political controversies or interpersonal communication.

My purpose in this text is to offer a general roadmap for navigating most current debates in the metaphysics of social categories regarding what sort of fact it is for a person to inhabit one social category or another—for example, what makes a person Mexican, or gay, or rich. With this goal in mind, I propose classifying the debating positions into three broad camps: common sense theories, socio-historical accounts, and performative theories. I characterise their main differences, identifying the main challenges (...) and achievements of each. I show that for persons well integrated into their categories, the differences between these three broad camps are minuscule, yet become crucial when we try to account for people not so well integrated. Then, I sketch a pluralist proposal that reconciles the three camps I have identified, while doing justice to the challenges presented by interstitial phenomena such as mestizaje, transition, passing, migration, etc. (shrink)

Este breve ensayo se inscribe en la tradición de buscar similitudes entre los epítetos y otros fenómenos lingüísticos, tanto inofensivos como discriminatorios.

Tracing the leading role of emotions in the evolution of the mind, a philosopher and a psychologist pair up to reveal how thought and culture owe less to our faculty for reason than to our capacity to feel. Many accounts of the human mind concentrate on the brain’s computational power. Yet, in evolutionary terms, rational cognition emerged only the day before yesterday. For nearly 200 million years before humans developed a capacity to reason, the emotional centers of the brain were (...) hard at work. If we want to properly understand the evolution of the mind, we must explore this more primal capability that we share with other animals: the power to feel. Emotions saturate every thought and perception with the weight of feelings. The Emotional Mind reveals that many of the distinctive behaviors and social structures of our species are best discerned through the lens of emotions. Even the roots of so much that makes us uniquely human—art, mythology, religion—can be traced to feelings of caring, longing, fear, loneliness, awe, rage, lust, playfulness, and more. From prehistoric cave art to the songs of Hank Williams, Stephen T. Asma and Rami Gabriel explore how the evolution of the emotional mind stimulated our species’ cultural expression in all its rich variety. Bringing together insights and data from philosophy, biology, anthropology, neuroscience, and psychology, The Emotional Mind offers a new paradigm for understanding what it is that makes us so unique.

This paper describes some epistemic cultural considerations which shape the uses of psychology. I argue the study of mind is bound by the metaphysical background of the given locale and era in which it is practiced. The epistemic setting in which psychology takes place will shape what is worth observing, how it is to be studied, how the data is to be interpreted, and the nature of the ultimate explanatory units. To demonstrate conceptual epistemic constraints, I discuss metaphor use in (...) psychology. In addition, epistemic constraints shape the praxes that arise from structural study of the mind. In order to illustrate this cultural constraint, I discuss Soviet Psychology and provide a contrast between practical uses of psychoanalysis in India, Egypt, and rural Ghana. In response to these conceptual and practical epistemic limitations, psychology could adapt methods drawn from history and anthropology. (shrink)

This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images but (...) that “consistency should suffice for truth” (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

In his Vermischte Bemerkungen 43, Wittgenstein notices that he was also influenced by Oswald Spengler. The paper deals with the question of in which way Spengler influenced Wittgenstein’s late works and if it really was influence or only a coincidence of ideas.

The recent discussion of fictional models has focused on imagination, implicitly considering fictions as something nonconcrete. We present two cases from synthetic biology that can be viewed as concrete fictions. Both minimal cells and alternative genetic systems are modal in nature: they, as well as their abstract cousins, can be used to study unactualized possibilia. We approach these synthetic constructs through Vaihinger’s notion of a semi-fiction and Goodman’s notion of semifactuality. Our study highlights the relative existence of such concrete fictions. (...) Before their realizations neither minimal cells nor alternative genetic systems were any well-defined objects, and the subsequent experimental work has given more content to these originally schematic imaginings. But it is as yet unclear whether individual members of these heterogeneous groups of somewhat functional synthetic constructs will eventually turn out to be fully realizable, remain only partially realizable, or prove outright impossible.

The article examines the Socratic principle that (1) virtue is knowledge and its corollary that (2) nobody errs voluntarily (nemo sua sponte peccat). It tries to show (I) that both principles are paradoxa, i.e. from a phenomenological point of view, they seem to be false; (II) that nevertheless the platonic Socrates accepts both principles as true; and finally (III) that these principles are analytical truths a priori which can only be understood if a person (soul) finds them in him- or (...) herself.

Recent epistemology of modality has seen a growing trend towards metaphysics-first approaches. Contrastingly, this paper offers a more philosophically modest account of justifying modal claims, focusing on the practices of scientific modal inferences. Two ways of making such inferences are identified and analyzed: actualist-manipulationist modality and relative modality. In AM, what is observed to be or not to be the case in actuality or under manipulations, allows us to make modal inferences. AM-based inferences are fallible, but the same holds for (...) practically all empirical inquiry. In RM, modal inferences are evaluated relative to what is kept fixed in a system, like a theory or a model. RM-based inferences are more certain but framework-dependent. While elements from both AM and RM can be found in some existing accounts of modality, it is worth highlighting them in their own right and isolating their features for closer scrutiny. This helps to establish their relevant epistemologies that are free from some strong philosophical assumptions often attached to them in the literature. We close by showing how combining these two routes amounts to a view that accounts for a rich variety of modal inferences in science. (shrink)

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

Semantic analysis in early analytic philosophy belongs to a long tradition of adopting geometrical methodologies to the solution of philosophical problems. In particular, it adapts Descartes’ development of formalization as a mechanism of analytic representation, for its application in natural language semantics. This article aims to trace the mathematical roots of Frege, Russel and Carnap’s analytic method. Special attention is paid to the formal character of modern analysis introduced by Descartes. The goal is to identify the particular conception of “form” (...) developed by the analytic tradition, from Descartes to early analytic philosophy, and to determine its relation to similar notions, like ‘function’ and ‘syntax’. Finally, I focus on how Frege, Russell and Carnap’s methods of semantic analysis fit the general characterization of formal analysis previously developed. (shrink)

This article considers the historical tension in conceptualising Marx's materialism (dialectical and historical) as either a break from, or a fidelity to, Hegelian dialectics, and the methods by which this tension is itself subsumed under an insistence on vindicating the radical irreducibility of Marxist thought. Ultimately, however, it is argued that the question of whether Marx should or should not be framed alongside Hegel is the wrong question. It is not a question of 'Marx by himself' or 'Marx and... [Hegel]', (...) but rather of 'Marx without himself': as with any radical event in the history of ideas, it is a benefit to Marx's innovativeness that he can be retrospectively articulated according to historical traditions whilst simultaneously breaking from them. -/- .

A strange dialectical reversal characterizes the oppositions which psychoanalysis posits against philosophy and neuroscience: what psychoanalysis intervenes with as a unique and missing quality of these subjects, reveals itself upon enquiry as already having been a feature of said subjects. This article first discusses the failed intervention of psychoanalysis within the perceived totalities and absolutes of German idealism. Psychoanalysis, founded on an ontological division and internal inconsistency with a retroactive logic, finds this internal contradiction already reflected within the supposed totalities (...) of Schelling and Hegel. Schelling’s “blind act,” a decision with no prior foundation that grounds an abstract identity-in-itself, appears as the counterpart to what Badiou calls the strictly “analytic act.” Hegel’s Science of Logic, in which the inconclusive interpenetration of being and nothing presupposes its own conclusion in the transitions to essence, and in which an internal incompleteness and contradiction are retroactively constitutive of the concept, similarly nullifies the intervention of psychoanalysis. Finally, precisely such a reversal is presented in neuroscience, where the constitutive contradiction of contingently functional neuronal formations in the adaptive “multiple demand” model of executive functioning repeats the contingent and self-contradicting psychoanalytic subject as being its own deference within linguistic, discursive formations.

The first chapter, "Der Hintergrund von Gadamers 'Phänomenologischen Interpretationen' in Sein und Zeit" traces the origins of Gadamer’s interpretation of the Philebus in Sein und Zeit. Especially important is that Dasein is, thanks to speech , already outside of itself in the world. The second chapter "Gadamers Dialektische Ethik" gives a short summary of the main points of Gadamer's interpretation of the Philebus. The third chapter "Davidsons reinterpretation of von Gadamer's Dialektischer Ethik" 222-231), points especially to the fact that Davidson (...) sees the "Socrates post Vlastos" in the interpretation of Gadamer at work: Because every man is already in possession of some basic truths, coherence is enough to lead to substantive truths. Davidson concludes that only in “interpersonal communication” "can be thought, a grasping of the fact of an objective, that is, a shared world". Thus, Davidson sees in Gadamer's interpretation of the Philebus his own theory of triangulation anticipated. (shrink)

The debate over Plato’s “ so called unwritten doctrines”, which he communicated only to a small circle of trusted disciples, has caused a stir among philosophers in recent decades. Rafael Ferber assumes a differentiated position in this controversy. He is convinced that the unwritten doctrines did exist, but that Plato, for reasons inherent in the process of gaining knowledge, was unable to communicate these doctrines even to his closest disciples. In this book, Ferber outlines the discussion and summarizes the (...) standpoints of greatest interest. Ever since Aristotle, we have known that Plato did not put his most important teachings into writing, but instead communicated them only orally to the inner circle of his disciples. While the extant dialogues merely pass down Plato’s “exoteric” doctrines, his most important “esoteric” insights were not meant for the general public. In the meantime, the contents and the significance of Plato’s “unwritten doctrines” have become the subject of debate in philosophical circles. Fifteen years ago, at the height of the controversy over the “unwritten doctrines”, Rafael Ferber entered the fray with a small book. He proposed that Plato was also unable to communicate the “unwritten doctrines” because the highest principles (i.e. the subject of the unwritten doctrines) cannot be known through logical operations due to an epistemological paradox. Ferber’s differentiated position met with great respect and acceptance, although in individual cases it was also rejected. Ferber’s new book again presents the text of 1991, but significantly expands on it through new perspectives and an outline of the discussion it triggered. In this book, the reader learns what is meant by Plato’s unwritten doctrines and what the controversy is all about. (shrink)

Is there a notion of domain specificity which affords genuine insight in the context of the highly modular mind, i.e. a mind which has not only input modules, but also central ‘conceptual’ modules? Our answer to this question is no. The main argument is simple enough: we lay out some constraints that a theoretically useful notion of domain specificity, in the context of the highly modular mind, would need to meet. We then survey a host of accounts of what domain (...) specificity is, based on the intuitive idea that a domain specific mechanism is restricted in the kind of information that it processes, and show that each fails at least one of those constraints.

Pronpongo una nueva manera de concebir la aceptación de proposiciones y su relación con la creencia y la inferencia. Argumento además que adoptar esta propuesta nos permite resolver de manera relativamente sencilla algunas paradojas aparentemente tan disímbolas cómo la del prefacio, la lotería y el sorites. Según esta propuesta, el error detrás de la paradoja sorítica es pensar que quién cree que hay una línea divisoria entre lo que cae dentro de la extensión de un término y lo que cae (...) fuera de él debe creer también de algún lugar que ahí se encuentra dicha línea divisoria. Espero convencerlos de que no es así, y que por lo tanto, nuestros juicios de sentido común no nos llevan a ninguna contradicción. (shrink)

In The moral problem (1994), Michael Smith tries to link three conflicting theories that alone are intuitively plausible, nevertheless, they do not seem to work well together. The first proposes that moral judgments are in fact beliefs about objective matters. The second states the concept of “practicality requirement”. The third is a humean belief-desire psychology, i.e. if a moral judgment is sufficient to explain actions, then it must involve a desire. If that is the case, it cannot be simply a (...) belief. For Smith, any attempt to solve the moral problem must find a way to hold all three doctrines. I will argue that his solution rests on two false assumptions. The first, a rationalist one which supports that what we have reason to do is what we would desire to do if we were fully rational. The second is the internalist thesis about moral motivation according to which a person who believes she is morally required to do something is either necessarily motivated to do it or she is practically irrational. I will base my critics on four objections raised by Copp, Miller, Shafer-Landau, Brink and Sayre-McCord. (shrink)

In conversation we trust others to communicate successfully, to understand us, etc. because they have the adequate skills to be competent in the linguistic domain. In other words, to be trustworthy regarding an activity is nothing but to have the appropriate skills required for the activity. In the linguistic case, this means that being trustworthy regarding conversation is nothing but to have the capacity of partaking as a responsible participant in linguistic conversation, which requires having the appropriate linguistic skills. Now, (...) to trust someone in conversation one better know that the person one trusts is trustworthy in the relevant sense, that is, one need to know that she has the relevant linguistic skills. Thus, in order to maintain mutual trust, participants in conversation must track not so much the linguistic successes of other participants, but their linguistic skills, i.e. they must be able to trace their successes to the agent and not to external circumstances. But lucky successes do not manifest skill and therefore show no evidence of the true capacities of performers and, therefore, are useless for building trust. This is as much true in the linguistic realm as outside of it. We care about successes because they provide us with defeasible evidence of skills, but this evidence is defeated if such successes cannot be attributed to the agent, but are instead the product of lucky. Therefore, if we care about trust, that is, if we care about agents and their skills, we need to be wary of lucky successes. (shrink)
