Presentamos lo básico de la teoría relativista de la gravitación, con la inclusión de textos originales, de varios papeles, publicados entre 1987 y 2009, por sus autores: S. S Gershtein, A. A Logunov, Yu. M Loskutov y M. A Mestvirishvili junto con las introducciones, resúmenes y conclusiones elaborados por el autor de este papel. Esta es una teoría gauge, compatible con las teorías de la física cuántica de las fuerzas electromagnética, débil y fuerte, que define la gravedad como la cuarta (...) fuerza existente en la naturaleza, como campo estático dotada de la partícula transmisora del gravitón virtual de espines 2 y 0, dentro del espíritu del principio de relatividad de Galilei, en su generalización de la relatividad especial de Poincaré que le permitió a los autores la universalización de que las leyes físicas de la naturaleza se cumplen con independencia de los marcos de referencia donde se apliquen. No obstante, integrada a la teoría Entwurf de Grossmann-Einstein, en su desarrollo ulterior, por parte de estos autores, por lo tanto, preserva las leyes de conservación de la energía-impulso y del impulso angular conjuntamente del campo gravitacional y los demás campos materiales existentes en la naturaleza, en el espaciotiempo efectivo de Riemann, mediante su identidad con el espaciotiempo pseudo Euclídeo de Minkowski.

Con base en los varios papeles, 1989-2002, mediante los textos originales, se presenta la crítica, de los matemático-físicos A. Logunov y M. Mestvirishvil, de la “general relatividad” de A. Einstein, paso previo para la elaboración de la teoría relativista de la gravitación de estos autores. Se demuestra concluyentemente que desde las ecuaciones de Einstein-Grossman-Hilbert la gravedad es absurdamente un campo métrico carente de realidad física.

En las actividades ordinarias de nuestra vida cotidiana encontramos nuestros actos de percepción confrontados por las cosas materiales. A ellos ─actos de percepción─ les atribuimos una existencia "real" asumiéndolos de tal manera que los sumergimos y transfundimos, de forma múltiple e indefinida, dentro del entorno de realidades análogas que se unen para formar un único mundo al que yo, con mi propio cuerpo, pertenezco. Ahora bien sí frente a la cotidianidad descrita anteriormente asumimos una actitud escéptica acerca de lo que (...) es “real” en el mundo,nos descubriremos haciendo una reflexión filosófica. Bajo esta deliberación encontramos que, por ejemplo, la cualidad "verde", tiene existencia por medio de la sensación "verde"asociada a un objeto dado por la percepción, lo que nos lleva a pensar que no tiene sentido vincularla sensación como cosa en sí misma a cosas materiales existentes en sí mismos , esto nos lleva a pensar que las cualidades de los sentidostienen carácter subjetivo.A pesar de esta reflexión es conveniente acotar que esta subjetividad no interesaa las ciencias exactas ya que éstas procuran lo objetivo. -/- Desde este punto de vista,encontramos dentro de los estudios de Galileo Galilei el principio que subyace al método matemáticoconstructivo de nuestra física moderna ; de esta manera, y bajo este principio,los colores ─ por ejemplo “verde”─ son solo vibraciones en un medio repudiando de esta forma el carácter subjetivo a la vez que se mantiene la objetividad. Sin embargo, dentro del campo de la filosofía el idealismo transcendental de Kant marca un cambio de paradigma en relación a lo anterior. Kant sostiene que no solamente las cualidades de los sentidos tienen carácter subjetivo, sino que espacio y tiempo, conceptos fundacionales dentro de la física, no tienen significación absoluta; en otras palabras, espacio y tiempo son formas de nuestra percepción . Para Kant aquello que sustenta nuestra percepción y aquello que sustenta el conocimiento matemático aplicado a la experiencia son lo mismo: intuiciones puras a priori del espacio y el tiempo. De esta manera, y bajo esta perspectiva, sólo la teoría de la relatividad deja muyen claro que las dos esencias: espacio y tiempo, como formas de la intuición en términos kantianos, no tienen lugar en el mundo construido por la física matemática concebida por Galileo . -/- Según esto, los colores no son siquiera vibraciones en un medio sino simplemente una serie de valores de funciones matemáticas en las que se producen cuatro parámetros independientes que corresponden a las tres dimensiones del espacio y la del tiempo, expresado como principio general esto significa que el mundo real y cada uno de sus constituyentes con sus características sólo pueden ser, en términos husserlianos, objetos intencionales de actos de conciencia . En otras palabras: los datos inmediatos que recibo son las experiencias de la conciencia. Esto nos permite afirmar que la sensación de un objeto está presente de una forma físicamente real para mí con quien esa sensación se relaciona. Esto es lo que Brentano llama objeto intencional ;es así como al percibir un objeto, por ejemplo: veo este “libro” mi atención está totalmente dirigida hacia él. Yo "tengo" la percepción, pero sólo cuando hago de esta percepción ─ acto libre de reflexión ─algo que "conozco" con respecto a ella ─y no sólo el “libro”─ llego precisamente a un segundo acto: objetos intencionales de actos de conciencia, que son a los que referíamos antes . -/- El objeto intencional es inmanente y lo que es inmanente es absoluto ; es exactamente lo que es en la forma en que lo tengo, y puedo reducir esto, su esencia, por los actos de reflexión . En otras palabras, es un componente real de mis experiencias; contrario a lo que sucede con el acto primario de percepción, donde el objeto es trascendental , esto es, se da en una experiencia de conciencia pero no es un componente real de la misma. Por otra parte, los objetos trascendentales tienen sólo una existencia fenoménica; son apariencias que se presentan de múltiples maneras. Ninguno de estos modos de aparición puede pretender presentar aquello que percibimos – por ejemplo el libro- tal como es en sí, además en toda percepción está involucrada la tesis de la realidad del objeto que aparece en ella; este último es, de hecho, un elemento fijo y duradero de la tesis general de la realidad del mundo . En resumen, lo que interesa ver claramente es la importancia enel dato de la conciencia como punto de partida en el que debemos situarnos si queremos comprender el significado absoluto . (shrink)

En este ensayo el autor supera la contradicción teórica existente entre la Relatividad General que define el campo gravitacional como un aspecto geométrico del espaciotiempo, bien como potencial o curvatura, y la Gravedad Cuántica que lo define como una fuerza de interacción fundamental, con el cambio de la concepción del espaciotiempo de propiedad geométrica estructural del campo gravitacional, a la concepción del espaciotiempo propiedad geométrica estructural de la materia en movimiento. El espaciotiempo no es continente de la materia (...) (Substancialismo) sino que por el contrario está contenido en la materia en cuanto constituye la estructura geométrica que le da su forma y permite sus cambios, a la cual como espacio le confiere su capacidad de contener y como tiempo su capacidad de devenir. Tampoco, el espaciotiempo es la categoría de las relaciones geométricas de los cuerpos materiales y sus eventos (Relacionismo), puesto que, no es una propiedad relacional de la materia sino la propiedad estructural espacio-temporal geométrica de la materia, a la cual la dota con sus capacidades de auto contenerse y transformarse. La teoría del autor sobre el espaciotiempo es la de la materia intrínsecamente dinámica, dotada estructuralmente de las cuatro dimensiones de espaciotiempo, autocontenida espacialmente y auto deviniendo temporalmente, puesto, que la materia en su capacidad de contener dinámicamente ésta ensimisma contenida y transformándose. La partícula-onda, de la materia y del campo, no existe en el espaciotiempo, sino que éste es la propiedad geométrica intrínseca estructural de la partícula-onda, por lo tanto, adherida a su propia naturaleza interna, como su propiedad geométrica dimensional intrínseca, que con fuerza de ley se manifiesta en sus mediciones cuantitativas, bien cuando es tomada la partícula-onda en sí o en relación con otras. Así, sólo son posibles las teorías sobre la gravedad provenientes de la Gravedad Cuántica, aunque, deben reformularse renunciando a integrarlas con la visión geométrica derivada de las ecuaciones de la llamada “General Relatividad”.

Desde un enfoque epistemológico se busca hacer la crítica de la relatividad general en el momento en que se formula una teoría cuántica sobre la gravedad (año 1967). Como consecuencia de la restauración de la concepción física sobre la geométrica de la gravedad, en una física de partículas-ondas, se plantea, mediante un análisis formal de estructura, que el gravitón-onda gravitatoria tendrá una velocidad mayor que c.

En el ámbito de la teoría general de la relatividad (TGR), se considera que el espaciotiempo es una entidad real. En este sentido, atendiendo al realis mo sobre entidades, surgen problemas como ¿qué tipo de entidad es el espaciotiempo?, ¿cuál es su naturaleza? Tradicionalmente, en atención a dicha teoría conviven dos concepciones realistas: la substancialista, donde el espaciotiempo sería una substancia; y la relacionista, tal que el espaciotiempo correspondería a una “relación entre substancias”.

El autor presenta la historia de las ondas gravitacionales según Einstein, uniéndola a su biografía y a su época con el fin de comprenderla en su conexión con la historia de los semitas, la personalidad de Einstein en el manejo de sus circunstancias generadoras de conflicto en sus relaciones de competencia con sus colegas y en la formulación de la llamada teoría general de la relatividad. Recaeremos en las vicisitudes que vivió Einstein en el tránsito de que su (...) trabajo científico pasara a la ciencia normal como un pilar de la física teórica. Trataremos como Einstein introdujo el éter relativístico confiriéndole un “olor de materialidad” a su explicación geométrica de la gravedad, donde indudablemente, no cabe, pero que él tuvo que ceder ante la presión eso sí justificada de sus más connotados colegas, liderados por Lorentz. Einstein lo tuvo que hacer para mantenerse en la cola que lo llevaría al Nobel. Fue así, como desarrollando el hilo del éter relativista, en junio de 1916, introdujo las ondas gravitacionales de las que, en un acto de liberación personal y honradez científica, cuando pudo, en 1938, demostró como no podían existir, dentro del escenario de su relatividad, para de inmediato también darle fin al éter relativista.

Algunos defensores del realismo científico, particularmente Ilkka Niiniluoto y Philip Kitcher, han intentado moderar las tesis ontológicas más fuertes del realismo buscando la integración de la teoría de la verdad como correspondencia con alguna versión matizada del relativismo conceptual propugnado por Putnam, según el cual el mundo carece de una estructura propia y, por tanto, la ontología depende de nuestros esquemas conceptuales. No es claro, sin embargo, que ambas cosas se puedan armonizar fácilmente. Si nuestro conocimiento del mundo está mediado (...) por nuestras categorías y conceptos, y si además la elección de esas categorías y conceptos puede variar en función de nuestros intereses y no obedecen a la existencia de unos supuestos géneros naturales o a una estructura propia del mundo, se torna entonces problemático establecer a qué corresponden nuestros enunciados verdaderos. ¿Corresponden al mundo independiente de nuestra mente o al mundo estructurado por nosotros mediante nuestras categorías y conceptos? En este artículo se presentarán las principales dificultades que encuentra este proyecto de realismo moderado tanto en Niiniluoto como en Kitcher, se analizarán sus propuestas para solventar dichas dificultades, mostrando sus insuficiencias y, finalmente, se propondrá una modalidad de realismo ontológico moderado que, recogiendo algo del espíritu de la relatividad conceptual de Putnam, es lo suficientemente fuerte como para sustentar una teoría de la verdad como correspondencia.

What explains the truth of a universal generalization? Two types of explanation can be distinguished. While an ‘instance-based explanation’ proceeds via some or all instances of the generalization, a ‘generic explanation’ is independent of the instances, relying instead on completely general facts about the properties or operations involved in the generalization. This intuitive distinction is analyzed by means of a truthmaker semantics, which also sheds light on the correct logic of quantification. On the most natural version of the semantics, (...) this analysis vindicates some claims made—without a proper defense—by Michael Dummett, Solomon Feferman, and others. Where instance-based explanations are freely available, classical logic is shown to be warranted. By contrast, intuitionistic logic remains warranted regardless of what explanations are available.

Parece haber una inconsistencia en el hecho de que se acepta que en la historia de la ciencia hay cambios teóricos con cambio de ontologías, de maneras de explicar, de términos y significados científicos, se descubren cosas nuevas, se modifican teorías vigentes, surgen nuevas disciplinas científicas y se formulan nuevas teorías sobre nuevos aspectos de la realidad, y también que, según la propia ciencia, la realidad no permanece fija (pues El Universo se expande, antes no había seres vivientes en La (...) Tierra, robots ni organismos genéticamente modificados, surgen nuevas especies, hay glaciaciones y cosas así) y, sin embargo, al mismo tiempo se suele considerar que lo que el conocimiento científico afirma que existe es lo que existe y se comporta como él lo describe. Pero lo que la ciencia afirma que existe es su ontología, un conjunto de referentes de expresiones lingüísticas que las personas incorporamos en nuestra idea de realidad, de modo que luego de un cambio ontológico ésta resulta modificada y –por ejemplo- ya no creemos que exista el flogisto o un espacio físico absoluto, sino otras cosas. Esto significa que hablar de galaxias o de virus es usar un metalenguaje que se refiere a ciertas teorías científicas, y que decir que existen galaxias es asumir metalingüísticamente la ontología de la ciencia actual: las personas hoy no creen que exista el flogisto ni lo afirman porque no lo afirma la ciencia (no es un referente científico). Consecuentemente, no es adecuado interpretar que una oración como “existen planetas” es verdadera en el sentido correspondentista (que es parte del realismo metafísico de la vida cotidiana o actitud natural y del lenguaje humano), porque todo argumento que afirme la existencia de algo independientemente de él, en realidad, lo supone al adoptar una ontología. Si no fuese así, cuando en el pasado se creía y se afirmaba la existencia del flogisto, miasmas o un espacio físico absoluto porque la ciencia lo afirmaba, esas oraciones hubiesen sido correspondentistamente verdaderas y habrían designado partes de la realidad: el flogisto, miasmas y el espacio físico absoluto.

This is the general introduction to the edited collection "A companion to Experimental Philosophy".

As the principle of natural selection is generalized to explain (adaptive) patterns of human behavior, it becomes less clear what the selective environment empirically refers to. While the environment and individual are relatively separable in the non-human biological context, they are highly entangled in the context of moral, social, and institutional evolution. This chapter brings attention to the problem of generalizing the selective environment, and argues that it is ontologically disunified and definable only through its explanatory function. What unifies the (...) selective environment is that it explains adaptation in a non-agential way, by screening off various forms of agency, whether divine, organismic, or human. This explanatory function of the selective environment helps avoid some sources of confusion when the theory of natural selection is applied to humanities and social sciences. (shrink)

Hossack's 'The Metaphysics of Knowledge' develops a theory of facts, entities in which universals are combined with universals or particulars, as the foundation of his metaphysics. While Hossack argues at length that there must be negative facts, facts in which the universal 'negation' is combined with universals or particulars, his conclusion that there are also general facts, facts in which the universal 'generality' is combined with universals, is reached rather more swiftly. In this paper I present Hossack with three (...) arguments for his conclusion. They all draw, as does Hossack's theory of facts, on views Russell expressed in various writings. Two arguments are based on Russell's explanation of universals as aspects of resemblance; the third on Russell's observation that general propositions do not follow logically from exclusively particular premises. Comparison with other metaphysics of generality show them to be wanting and Russell's and Hossack's accounts superior. (shrink)

El tema central de esta tesis de maestría en filosofía de la ciencia es el de la naturaleza de la persistencia a través del tiempo, en el contexto de nuestras mejores teorías físicas acerca del espacio-tiempo. Este problema involucra uno de los conceptos centrales en nuestra comprensión científica del mundo físico, a saber, el concepto de tiempo. La forma usual en que se plantea el problema de la persistencia involucra ciertas nociones que están conectadas con la física, pero estos supuestos (...) rara vez suelen ser formulados de manera explícita, empero, extrapolar las disputas filosóficas en torno a la naturaleza de la persistencia al contexto de espacios newtonianos, galileanos y relativistas (minkowski) no es una tarea trivial. Estos espacios son algunos de los espacios fundamentales donde ocurre la dinámica de los objetos físicos en física clásica. -/- En esta investigación he perseguido diferentes objetivos que vinculan el problema de la persistencia, las diferentes tesis que buscan resolver el problema y las estructuras espacio-temporales postuladas nuestras mejores teorías físicas: -/- 1. Articular el problema de la persistencia, así como varios supuestos de metafísica y filosofía de la ciencia indispensables para plantear la discusión, así como para formular mi solución. 2. Introducir a detalle las diversas estructuras-espacio temporales que, en nuestras mejores teorías de física, albergan a los objetos materiales persistentes. 3. Introducir herramientas formales que permitan analizar la relación de todo-parte en contextos temporales (mereología), así como las propiedades formales de la relación de ubicación que mantienen los objetos materiales con las regiones espacio-temporales. 4. Reformular las posiciones, con estas herramientas, en las estructuras espacio-temporales previamente mencionadas. 5. Ofrecer una serie de argumentos que favorecen lo que más adelante caracterizo como “perdurantismo de ubicación”, desde dos posiciones metafísicas: el unitismo, la tesis de que el tiempo y el espacio son aspectos de una sustancia más fundamental, el espacio-tiempo y el supersustantivismo, la tesis de que el espacio-tiempo y sus propiedades son suficientes para dar soporte a una ontología realista en el caso de nuestras mejores teorías físicas. -/- De esos cinco puntos me ocupo, en ese orden, en los cinco capítulos de esta investigación, con el capítulo V siendo mi contribución original a la literatura especializada sobre el tema. En los primeros capítulos (I, II) el enfoque es en presentar una serie de posiciones y asunciones estructurales en filosofía y física. En los capítulos intermedios (III, IV), hay también una presentación de posiciones filosóficas dominantes en la literatura (Balashov, 2010; Gibson y Pooley, 2006; Gilmore, 2008, 2014; Calosi y Fano, 2015; Saucedo, 2011) que acompañan a una discusión de elementos formales de mereología y postulados estructurales de las teorías naturalizadas de persistencia a través del tiempo. El capítulo V, que es mi contribución original a la discusión filosófica, integra todo lo discutido en los capítulos anteriores en una serie de argumentos que presento en favor del perdurantismo de ubicación.

In this paper, I argue that Kant gives a philosophically plausible derivation of the general duty of benevolence and that this derivation can be used to show how to derive other general duties of commission with the universalizability tests. The paper is divided into four sections. In the first, I explain Kant’s notion of a general duty. In the second, I introduce the universalizability tests. In the third, I examine and argue against an account in the secondary (...) literature of how to derive general duties from these tests. In the fourth, I look at Kant’s derivation of the duty of benevolence in the Metaphysics of Morals, and I suggest how this reasoning can be extended to other duties. (shrink)

I address a type of circularity threat that arises for the view that we employ general basic logical principles in deductive reasoning. This type of threat has been used to argue that whatever knowing such principles is, it cannot be a fully cognitive or propositional state, otherwise deductive reasoning would not be possible. I look at two versions of the circularity threat and answer them in a way that both challenges the view that we need to apply general (...) logical principles in deductive reasoning and defuses the threat to a cognitivist account of knowing basic logical principles.

Vogel argues that sensitivity accounts of knowledge are implausible because they entail that we cannot have any higher-level knowledge that our beliefs are true, not false. Becker and Salerno object that Vogel is mistaken because he does not formalize higher-level beliefs adequately. They claim that if formalized correctly, higher-level beliefs are sensitive, and can therefore constitute knowledge. However, these accounts do not consider the belief-forming method as sensitivity accounts require. If we take bootstrapping as the belief-forming method, as the discussed (...) cases suggest, then we face a generality problem. Our higher-level beliefs as formalized by Becker and Salerno turn out to be sensitive according to a wide reading of bootstrapping, but insensitive according to a narrow reading. This particular generality problem does not arise for the alternative accounts of process reliabilism and basis-relative safety. Hence, sensitivity accounts not only deliver opposite results given different formalizations of higher-level beliefs, but also for the same formalization, depending on how we interpret bootstrapping. Therefore, sensitivity accounts do not fail because they make higher-level knowledge impossible, as Vogel argues, and they do not succeed in allowing higher-level knowledge, as Becker and Salerno suggest. Rather, their problem is that they deliver far too heterogeneous results. (shrink)

I present and defend the generalized selected effects theory (GSE) of function. According to GSE, the function of a trait consists in the activity that contributed to its bearer’s differential reproduction, or differential retention, within a population. Unlike the traditional selected effects (SE) theory, it does not require that the functional trait helped its bearer reproduce; differential retention is enough. Although the core theory has been presented previously, I go significantly beyond those presentations by providing a new argument for GSE (...) and defending it from a recent objection. I also sketch its implications for teleosemantics and philosophy of medicine. (shrink)

Many scientists routinely generalize from study samples to larger populations. It is commonly assumed that this cognitive process of scientific induction is a voluntary inference in which researchers assess the generalizability of their data and then draw conclusions accordingly. We challenge this view and argue for a novel account. The account describes scientific induction as involving by default a generalization bias that operates automatically and frequently leads researchers to unintentionally generalize their findings without sufficient evidence. The result is unwarranted, overgeneralized (...) conclusions. We support this account of scientific induction by integrating a range of disparate findings from across the cognitive sciences that have until now not been connected to research on the nature of scientific induction. The view that scientific induction involves by default a generalization bias calls for a revision of the current thinking about scientific induction and highlights an overlooked cause of the replication crisis in the sciences. Commonly proposed interventions to tackle scientific overgeneralizations that may feed into this crisis need to be supplemented with cognitive debiasing strategies against generalization bias to most effectively improve science.

In this paper, I argue that what counts as the proper function of a trait is a matter of the de facto perspective that the biological system, itself, possesses on what counts as proper functioning for that trait. Unlike non-perspectival accounts, internal perspectivalism does not succumb to generality problems. But unlike external perspectivalism, internal perspectivalism can provide a fully naturalistic, mind-independent grounding of proper function and natural norms. The attribution of perspectives to biological systems is intended to be neither metaphorical (...) nor anthropomorphic: I do not mean to imply that such systems thereby must possess agency, cognition, intentions, concepts, or mental or psychological states. Instead, such systems provide the grounding for norms of performance when they internally enforce their own standard of (i.e., their own perspective on) what constitutes proper functioning or malfunctioning. By operating with a fixed, determinate level of generality, such systems provide the basis for an account of proper function that is immune to generality problems. (shrink)

According to Intellectualism knowing how to V is a matter of knowing a suitable proposition about a way of V-ing. In this paper, I consider the question of which ways of acting might figure in the propositions which Intellectualists claim constitute the object of knowledge-how. I argue that Intellectualists face a version of the Generality Problem – familiar from discussions of Reliabilism – since not all ways of V-ing are such that knowledge about them suffices for knowledge-how. I consider various (...) responses to this problem, and argue that none are satisfactory. (shrink)

This paper focuses on how experiences of trauma can lead to generalized fear of people, objects and places that are similar or contextually or conceptually related to those that produced the initial fear, causing epistemic, affective, and practical harms to those who are unduly feared and those who are intimates of the victim of trauma. We argue that cases of fear generalization that bring harm to other people constitute examples of injustice closely akin to testimonial injustice, specifically, mnemonic injustice. Mnemonic (...) injustice is a label that has been introduced to capture how injustice can occur via the operation of human memory systems when stereotypes shape what is remembered. Here we argue that injustices can also occur via memory systems when trauma leads to a generalized fear. We also argue that this calls for a reformulation of the notion of mnemonic injustice.

In this paper, I examine Hume’s account of an important class of causal belief which he calls “general rules”. I argue that he understands general rules, like all causal beliefs, as lively ideas which are habitually associated with our impressions or memories. However, I argue, he believes that they are unlike any reflectively produced causal beliefs in that they are produced quickly and automatically, such that they occur independently of any other processes of reasoning. Given this, I argue, (...) Hume appears to understand general rules as relatively simple beliefs, expressible only via generic sentences, like “birds lay eggs”. (shrink)

Scientists may sometimes generalize from their samples to broader populations when they have not yet sufficiently supported this generalization. Do such hasty generalizations also occur in experimental philosophy? To check, we analyzed 171 experimental philosophy studies published between 2017 and 2023. We found that most studies tested only Western populations but generalized beyond them without justification. There was also no evidence that studies with broader conclusions had larger, more diverse samples, but they nonetheless had higher citation impact. Our analyses reveal (...) important methodological limitations of many experimental philosophy studies and suggest that philosophical training may not protect against hasty generalizations. (shrink)

In this dialogue, Mileva and Albert start to talk about physics and its subject matter, the physical. They end up in a situation that permits causal dependence between separate ontological domains. In this possible world, they continue talking. First, they Socratically agree that the physical is physical and only physical. Then, they call the physical an ontologically homogeneous domain. They then generalise the principle that the physical is causally unaffected by anything non-physical, into the principle that ontologically homogeneous domains do (...) not cause ontologically homogeneous domains. From a modern point of view talking about black hole singularities, they continue discussing the Chandrasekhar limit and the collapse of the physical laws as we know them. Mileva carries a burden and Albert stands up and carries it with her. The burden is an implication of the generalised principle. Relying on parsimony, only ontologically homogeneous domains are forbidden to cause ontologically homogeneous domains. This leaves the door open for ontologically heterogeneous domains to cause ontologically homogeneous domains. Also relying on parsimony, only ontologically homogeneous domains are forbidden to be caused by ontologically homogeneous domains and this allows ontologically heterogeneous domains to be caused by ontologically homogeneous domains. Ontologically heterogeneous domains, thus, are allowed to causally link ontologically homogeneous domains. Albert realises that the mathematical could qualify as an ontologically homogeneous domain and that the theoretical difficulties that are foreseen beyond the Chandrasekhar limit could be addressed by expanding physics into a context that contains also an ontologically heterogeneous domain. The theoretical difficulties beyond the Chandrasekhar limit would be due to an emergent mathematical-physical domain. Mileva concludes that Albert’s theory is not faulty but regional. A global theory would have to include the explanation of the mathematical-physical. (shrink)

Important features of space and time are taken to be missing in quantum gravity, allegedly requiring an explanation of the emergence of spacetime from non-spatio-temporal theories. In this paper, we argue that the explanatory gap between general relativity and non-spatio- temporal quantum gravity theories might significantly be reduced with two moves. First, we point out that spacetime is already partially missing in the context of general relativity when understood from a dynamical perspective. Second, we argue that most approaches (...) to quantum gravity already start with an in-built distinction between structures to which the asymmetry between space and time can be traced back.

[Edited from Conclusion section:] We have looked at various challenging issues to do with getting connectionism to cope with high-level cognitive activities such a reasoning and natural language understanding. The issues are to do with various facets of generalization that are not commonly noted. We have been concerned in particular with the special forms these issues take in the arena of propositional attitude processing. The main problems we have looked at are: (1) The need to construct explicit representations of generalizations, (...) not just generalize correctly to individual cases; (2) The need to be able to match two or more complex short-term information structures, to enable rapid generalization from recent examples rather than from long-term memories; (3) The need to represent and reason with anomalous combinations of concepts; (4) The need to perform embedded reasoning. This presents special problems for systems using non-concatenative representations (as in mainstream connectionist approaches). We also touched on vague quantification in attitude report complements. Neither this topic nor that of analogies between short-term structures (point 2) has been adequately addressed in the symbolic framework, let alone in connectionism. -/- The opportunities and problems covered are put forward as things worth being optimistic about or pessimistic about, respectively. They are not put forward as decisive arguments for or against connectionism. The hope is that this chapter contributes to a greater understanding of the connectionist/symbolist gap by presenting some unusual issues and by throwing new light on some well known ones. (shrink)

In this paper, I articulate and argue for a new truthmaker view of ontological commitment, which I call the “General Truthmaker View”: when one affirms a sentence, one is ontologically committed to there being something that makes true the proposition expressed by the sentence. This view comes apart from Quinean orthodoxy in that we are not ontologically committed to the things over which we quantify, and it comes apart from extant truthmaker views of ontological commitment in that we are (...) not ontologically committed to the truthmakers of our sentences.

The generalized Darwinian research programme accepts physicalism, but holds that all life is purposive in character. It seeks to understand how and why all purposiveness has evolved in the universe – especially purposiveness associated with what we value most in human life, such as sentience, consciousness, person-to-person understanding, science, art, free¬dom, love. As evolution proceeds, the mechanisms of evolution themselves evolve to take into account the increasingly important role that purposive action can play - especially when quasi-Lamarckian evolution by cultural (...) means comes into existence. This programme of research brings together, into a coherent field of inquiry, aspects of such diverse fields of research as orthodox Darwinian theory (given its purposive interpretation), the study of animal behaviour, palaeontology, archaeology, history, anthropology, psycho-neurology, artificial intelligence, psychology, sociology, philosophy, linguistics, semantics, history and philosophy of science, and history and philosophy of inquiry more generally (the history and philosophy of ideas and culture). The great advantage of the generalized Darwinian research programme is that it provides a framework for understanding the deeds, achievements and experiences of people in a way that is compatible with the kind of knowledge and understanding achieved in the physical sciences, without being reducible to such knowledge and understanding. It promises to enable us to understand ourselves as a part of the biological domain without our humanity, our distinctive human value, being in any way denied: persons are not reduced to animals, and nor are animals misconceived to be persons. It holds out the hope that we can come to understand the human world as an integral part of the natural world without the meaning and value of the human world being thereby conceptually annihilated. The programme specifies in general terms what we must seek to do in order to develop a coherent understanding of nature and of ourselves which does justice to the character of both. (shrink)

A distinction is drawn among predicates, open sentences (or open formulas), and general terms, including general-term phrases. Attaching a copula, perhaps together with an article, to a general term yields a predicate. Predicates can also be obtained through lambda-abstraction on an open sentence. The issue of designation and semantic content for each type of general expression is investigated. It is argued that the designatum of a general term is a universal, e.g., a kind, whereas the (...) designatum of a predicate is a class (or its characteristic function) and the designatum of an open sentence is a truth-value. Predicates and open sentences are therefore typically non-rigid designators. It is argued further that certain general terms, including phrases, are invariably rigid designators, whereas certain others (general definite descriptions) are typically non-rigid. Suitable semantic contents for predicates, open sentences, and general terms are proposed. Consequences for the thesis of compositionality are drawn. (shrink)

In this paper, I present a general theory of topological explanations, and illustrate its fruitfulness by showing how it accounts for explanatory asymmetry. My argument is developed in three steps. In the first step, I show what it is for some topological property A to explain some physical or dynamical property B. Based on that, I derive three key criteria of successful topological explanations: a criterion concerning the facticity of topological explanations, i.e. what makes it true of a particular (...) system; a criterion for describing counterfactual dependencies in two explanatory modes, i.e. the vertical and the horizontal; and, finally, a third perspectival one that tells us when to use the vertical and when to use the horizontal mode. In the second step, I show how this general theory of topological explanations accounts for explanatory asymmetry in both the vertical and horizontal explanatory modes. Finally, in the third step, I argue that this theory is universally applicable across biological sciences, which helps to unify essential concepts of biological networks. (shrink)

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the (...) normative principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

I consider difficult data involving the interaction of attitudes and conditionals, specifically non-doxastic attitude expressions like 'regret'. I first show that felicitous attitude conditionals in "ignorance contexts", where the relevant person doesn't know the antecedent is true, give rise to a number of difficult problems given widely held assumptions in semantics. I then argue that, even so, we should expect these conditionals to be true and reasonable to utter in ignorance contexts, given certain other kinds of attitude construction that tend (...) to involve free relatives like `whatever'. I then use that observation to explain many of the more puzzling aspects of these conditionals, and to show that we should treat felicitous doxastic attitude conditionals differently from felicitous non-doxastic ones. I leave explaining felicitous doxastic attitude conditionals for future work, but offer constraints on a satisfying explanation of them. (shrink)

We generalize, by a progressive procedure, the notions of conjunction and disjunction of two conditional events to the case of n conditional events. In our coherence-based approach, conjunctions and disjunctions are suitable conditional random quantities. We define the notion of negation, by verifying De Morgan’s Laws. We also show that conjunction and disjunction satisfy the associative and commutative properties, and a monotonicity property. Then, we give some results on coherence of prevision assessments for some families of compounded conditionals; in particular (...) we examine the Fréchet-Hoeffding bounds. Moreover, we study the reverse probabilistic inference from the conjunction Cn+1 of n + 1 conditional events to the family {Cn,En+1|Hn+1}. We consider the relation with the notion of quasi-conjunction and we examine in detail the coherence of the prevision assessments related with the conjunction of three conditional events. Based on conjunction, we also give a characterization of p-consistency and of p-entailment, with applications to several inference rules in probabilistic nonmonotonic reasoning. Finally, we examine some non p-valid inference rules; then, we illustrate by an example two methods which allow to suitably modify non p-valid inference rules in order to get inferences which are p-valid.

What does it mean for a general term to be rigid? It is argued by some that if we take general terms to designate their extensions, then almost no empirical general term will turn out to be rigid; and if we take them to designate some abstract entity, such as a kind, then it turns out that almost all general terms will be rigid. Various authors who pursue this line of reasoning have attempted to capture Kripke’s (...) intent by defining a rigid general term as one that applies to the objects in its extension essentially. I argue that this account is significantly mistaken for various reasons: it conflates a metaphysical notion (essentialism) with a semantic one (rigidity); it fails to countenance the fact that any term can be introduced into a language by stipulating that it be a rigid designator; it limits the extension of rigid terms so much that terms such as ‘meter’, ‘rectangle’, ‘truth’, etc. do not turn out to be rigid, when they obviously are; and it wrongly concentrates on the predicative use of a general term in applying a certain test offered by Kripke to determine whether a term is rigid.

Jeff Paris proves a generalized Dutch Book theorem. If a belief state is not a generalized probability then one faces ‘sure loss’ books of bets. In Williams I showed that Joyce’s accuracy-domination theorem applies to the same set of generalized probabilities. What is the relationship between these two results? This note shows that both results are easy corollaries of the core result that Paris appeals to in proving his dutch book theorem. We see that every point of accuracy-domination defines a (...) dutch book, but we only have a partial converse. (shrink)

Metacognition is the capacity to evaluate the success of one's own cognitive processes in various domains; for example, memory and perception. It remains controversial whether metacognition relies on a domain-general resource that is applied to different tasks or if self-evaluative processes are domain specific. Here, we investigated this issue directly by examining the neural substrates engaged when metacognitive judgments were made by human participants of both sexes during perceptual and memory tasks matched for stimulus and performance characteristics. By comparing (...) patterns of fMRI activity while subjects evaluated their performance, we revealed both domain-specific and domain-general metacognitive representations. Multivoxel activity patterns in anterior prefrontal cortex predicted levels of confidence in a domain-specific fashion, whereas domain-general signals predicting confidence and accuracy were found in a widespread network in the frontal and posterior midline. The demonstration of domain-specific metacognitive representations suggests the presence of a content-rich mechanism available to introspection and cognitive control. (shrink)

Examining the significance of the General’s enlightenment in the Platform Sutra, this article clarifies the fundamental role that emotions play in the development of one’s spiritual understanding. In order to do so, this article emphasizes that the way to enlightenment implicit in the story of the General and the Master involves first granting negative emotions a means for productive expression. By acting as a preparatory measure for calming the mind and surrendering control over it, human passions become a (...) necessary, antecedent condition to wisdom—a conclusion that this article argues is a major, and sometimes underappreciated, lesson embedded in the teachings of the Sixth Patriarch.

The ultimate goal of research into computational intelligence is the construction of a fully embodied and fully autonomous artificial agent. This ultimate artificial agent must not only be able to act, but it must be able to act morally. In order to realize this goal, a number of challenges must be met, and a number of questions must be answered, the upshot being that, in doing so, the form of agency to which we must aim in developing artificial agents comes (...) into focus. This chapter explores these issues, and from its results details a novel approach to meeting the given conditions in a simple architecture of information processing. (shrink)

A general framework for translating various logical systems is presented, including a set of partial unary operators of affirmation and negation. Despite its usual reading, affirmation is not redundant in any domain of values and whenever it does not behave like a full mapping. After depicting the process of partial functions, a number of logics are translated through a variety of affirmations and a unique pair of negations. This relies upon two preconditions: a deconstruction of truth-values as ordered and (...) structured objects, unlike its mainstream presentation as a simple object; a redefinition of the Principle of Bivalence as a set of four independent properties, such that its definition does not equate with normality.

Since Saul Kripke’s influential work in the 1970s, the revisionary approach to semantic paradox—the idea that semantic paradoxes must be solved by weakening classical logic—has been increasingly popular. In this paper, we present a new revenge argument to the effect that the main revisionary approaches breed new paradoxes that they are unable to block.

The dynamics of general relativity is encoded in a set of ten differential equations, the so-called Einstein field equations. It is usually believed that Einstein's equations represent a physical law describing the coupling of spacetime with material fields. However, just six of these equations actually describe the coupling mechanism: the remaining four represent a set of differential relations known as Bianchi identities. The paper discusses the physical role that the Bianchi identities play in general relativity, and investigates whether (...) these identities --qua part of a physical law-- highlight some kind of a posteriori necessity in a Kripkean sense. The inquiry shows that general relativistic physics has an interesting bearing on the debate about the metaphysics of the laws of nature. (shrink)

On Kripke’s intended definition, a term designates an object x rigidly if the term designates x with respect to every possible world in which x exists and does not designate anything else with respect to worlds in which x does not exist. Kripke evidently holds in Naming and Necessity, hereafter N&N (pp. 117–144, passim, and especially at 134, 139–140), that certain general terms – including natural-kind terms like ‘‘water’’ and ‘‘tiger’’, phenomenon terms like ‘‘heat’’ and ‘‘hot’’, and color terms (...) like ‘‘blue’’ – are rigid designators solely as a matter of philosophical semantics (independently of empirical, extra-linguistic facts). As a consequence, Kripke argues, identity statements involving these general terms are like identity statements involving proper names (e.g., ‘‘Clark Kent=Superman’’) in that, solely as a matter of philosophical semantics, they express necessary truths if they are true at all. But whereas it is reasonably clear what it is for a (first-order) singular term to designate, Kripke does not explicitly say what it is for a general term to designate. General terms are standardly treated in modern logic as predicates, usually monadic predicates. There are very forceful reasons – due independently to Church and Godel, and ultimately to Frege – for taking predicates to designate their semantic extensions. But insofar as the extension of the general term ‘‘tiger’’ is the class of actual tigers (or its characteristic function), it is clear that the term does not rigidly designate its extension, since the class of tigers in one possible world may differ from the class of tigers in another. What, then, is it for ‘‘tiger’’ to be rigid? (shrink)

The present paper was written as a contribution to ongoing methodological debates within the NCC project. We focus on the neural correlates of conscious perceptual episodes. Our claim is that the NCC notion, as applied to conscious perceptual episodes, needs to be reconceptualized. It mixes together the processing related to the perceived contents and the neural substrate of consciousness proper, i.e. mechanisms making the perceptual contents conscious. We thus propose that the perceptual NCC be divided into two constitutive subnotions. The (...) main theoretical idea that emerges as a consequence of this reconceptualization is that the neural correlate of a perceptual episode is formed in the neural interaction between content-processing and consciousness-conferring mechanisms. The paper elaborates this distinction, marshals some initial arguments in its favour, and tests it against some of the most debated theories of consciousness. (shrink)

In this paper I will give an analysis of what I call ‘generalizing detached self-reference’ within a general account of reference to the first person. With generalizing detached self-reference an agent attributes properties to a range of individuals by putting himself into their shoes, or simulating them. I will show that generalizing detached self-reference plays an important role in the semantics of natural language, in particular in the English generic one and in what syntacticians call arbitrary PRO.

Bilateral proof systems, which provide rules for both affirming and denying sentences, have been prominent in the development of proof-theoretic semantics for classical logic in recent years. However, such systems provide a substantial amount of freedom in the formulation of the rules, and, as a result, a number of different sets of rules have been put forward as definitive of the meanings of the classical connectives. In this paper, I argue that a single general schema for bilateral proof rules (...) has a reasonable claim to inferentially articulating the core meaning of all of the classical connectives. I propose this schema in the context of a bilateral sequent calculus in which each connective is given exactly two rules: a rule for affirmation and a rule for denial. Positive and negative rules for all of the classical connectives are given by a single rule schema, harmony between these positive and negative rules is established at the schematic level by a pair of elimination theorems, and the truth-conditions for all of the classical connectives are read off at once from the schema itself.
