Dynamic, embodied and situated cognition set up organism-environment interaction — agency for short — as the core of cognitive systems. Robotics became an important way to study this behavioral kernel of cognition. In this paper, we discuss the implications of what we call the biological grounding problem for robotic studies: Natural and artificial agents are hugely different and it will be necessary to articulate what must be replicated by artificial agents such as robots. Interestingly, once this issue is explicitly raised, (...) it seems that a full replication of biological features is required for cognition itself to be plausibly cast as a biological phenomenon. Several issues come to the fore once one takes this implication seriously. Why does a full biological interpretation of cognition remain so controversial? How does this impact the relevance of robotics for the study of cognition? We try to articulate and ease the various tensions that arise from this biological scenario. (shrink)

E. Machery, R. Mallon, S. Nichols and S. Stich, have argued that there is empirical evidence against Kripke’s claim that names are not descriptive. Their argument is based on an experiment that compares the intuitions about proper name use of a group of English speakers in Hong Kong with those of a group of non-Chinese American students. The results of the experiment suggest that in some cultures speakers use names descriptively. I argue that such a conclusion is incorrect, for the (...) experiment does not prove what it is purported to prove. (shrink)

Føllesdal (1966 and 1969) claims that modal distinctions collapse, that is that p and Necessarily p are equivalent, in any system of modal logic that incorporates a standard theory of definite descriptions, like the one proposed by Carnap in M&N. I argue that his argument fails.

According to Donnellan the characteristic mark of a referential use of a definite description is the fact that it can be used to pick out an individual that does not satisfy the attributes in the description. Friends and foes of the referential/attributive distinction have equally dismissed that point as obviously wrong or as a sign that Donnellan's distinction lacks semantic import. I will argue that, on a strict semantic conception of what it is for an expression to be a genuine (...) referential device, Donnellan is right: if a use of a definite description is referential, it must be possible for it to refer to an object independently of any attributes associated with the description, including those that constitute its conventional meaning.

This study examines whether character strengths predict resilience (operationalized as stable or higher mental health and subjective well-being despite an adverse event) over a period of approximately one month during the COVID-19 pandemic lockdown in Spain. Using a longitudinal design, participants (N = 348 adults) completed online measures of sociodemographic data, information regarding their situation in relation to the COVID-19, character strengths, general mental health, life satisfaction, positive affect and negative affect. All variables were measured at Time 1 and Time (...) 2, except for sociodemographic and most COVID-related information (Time 1 only). Time 1 data collection was conducted between March 21, 2020 and April 2, 2020, i.e., approximately the second week of lockdown in Spain. Time 2 data collection was conducted between April 24, 2020 and May 18, 2020, after the Spanish government announced ita intention to progressively release the lockdown. A principal component analysis of character strengths was conducted. Five character strength factors were extracted: fortitude, goodness, intellectual, interpersonal, and restraint. Factor structures at Times 1 and 2 were highly consistent. All character strength factors at Time 1 correlated positively with life satisfaction and positive affect, and negatively with negative affect and mental health at T2 (higher scores in the mental health measure indicate poorer mental health). Fortitude strengths showed the highest correlations. We conducted a series of regression analyses with strength factors at Time 1 as predictors, and mental health, life satisfaction, and positive and negative affect as dependent variables, controlling for their baseline levels. To test the directionality of the relationship between strengths and the dependent variables, all analyses were reversed. All character strength factors predicted an increase in mental health. They also predicted positive affect, with the exception of strengths of restraint. Fortitude, intellectual and interpersonal strengths predicted an increase in life satisfaction. Finally, fortitude strengths, interpersonal strengths, and strengths of restraint, predicted a decrease in negative affect. None of the reversed analyses yielded significant effects. Limitations, implications, and possible character strengths-based interventions aimed at promoting mental health in the COVID-19 pandemic are discussed. (shrink)

We defend the view that defines the rigidity of general terms as sameness of designated universal across possible worlds from the objection that such a characterization is incapable of distinguishing rigid from non-rigid readings of general terms and, thus, that it trivializes the notion of rigidity. We also argue that previous attempts to offer a solution to the trivialization problem do no succeed.

I argue that the debate on the division of labor between grammar and pragmatics, at least as it pertains to pragmatic free enrichment, needs to be better grounded empirically. Often, only a reduced set of facts from English is used to substantiate claims regarding pragmatic free enrichment. But considering a reduced set of facts from a single language can only afford limited (and, sometimes, wrong) results, because we can merely see whatever this one language chooses to express. Two cases studies (...) are presented: adjectival fragments, and implicit indefinite objects. A grammatical analysis is defended for them. (shrink)

The following Principle of Substitutivity holds for the former, but not for the latter sentence: (PS) The truth value of (the proposition expressed by) a sentence that contains an occurrence of t1 remains constant when t2 is substituted for t1, provided that t1 and t2 are codesignative singular terms. It is an undeniable fact that different sentences behave differently when it comes to which substitutions preserve their truth value. What is curious is that this fact has been presented by the (...) philosophical tradition as a puzzle. To be more precise, what is supposed to be puzzling is the breakdown of PS in some sentences. Meanwhile, it is assumed that everything is as it should be, that nothing needs to be explained when we observe that the substitution of 'the number of planets' for 'nine' in 'nine is greater than seven' guarantees the preservation of truth value, in spite of the fact that the subject matter of the former sentence and the subject matter of 'the number of planets is greater than seven' are radically different. The former sentence expresses a claim about numbers and their relationships, whereas the latter sentence makes an assertion about our solar system. (shrink)

John Hawthorne and David Manley (The Reference Book, OUP 2012) endorse a unified treatment of the semantics of four kinds of expressions that can be said to have referential uses: specific indefinite descriptions, definite descriptions, demonstratives and proper names. The semantic theory the authors propose treats all these expressions as having a quantificational structure that achieves uniqueness of application via the presence of covert material contributing to the restriction of the domain of quantification. I argue that there are reasons to (...) postulate disunity; reasons to set apart a class of purely referential expressions that do not just apply uniquely to an object via overt or covert restrictors, but that refer to it.

Editor's introduction to a section devoted to Ruth Barcan Marcus (1921-2012).

In this paper we introduce a game semantics for System P, one of the most studied axiomatic systems for non-monotonic reasoning, conditional logic and belief revision. We prove soundness and completeness of the game semantics with respect to the rules of System P, and show that an inference is valid with respect to the game semantics if and only if it is valid with respect to the standard order semantics of System P. Combining these two results leads to a new (...) completeness proof for System P with respect to its order semantics. Our approach allows us to construct for every inference either a concrete proof of the inference from the rules in System P or a countermodel in the order semantics. Our results rely on the notion of a witnessing set for an inference, whose existence is a concise, necessary and sufficient condition for validity of an inferences in System P. We also introduce an infinitary variant of System P and use the game semantics to show its completeness for the restricted class of well-founded orders. (shrink)

It took a very long time before I encountered the systematic study of religious processes and dynamics as a distinctive and expansive area of scholarship. Using an autobiographical account, I trace the development of my scholarship in the social scientific study of religion. I have now experienced a great diversity of approaches to the study of religion. Driven by insatiable curiosity and knowing that no one can capture religion comprehensively, I now am committed to stimulating imaginative, rigorous, and wide-ranging developments (...) in religious scholarship. We require new, inventive, and even incompatible approaches to our study of religion if we ever hope to try adequately grasping the richness of religion. (shrink)

We prove completeness of preferential conditional logic with respect to convexity over finite sets of points in the Euclidean plane. A conditional is defined to be true in a finite set of points if all extreme points of the set interpreting the antecedent satisfy the consequent. Equivalently, a conditional is true if the antecedent is contained in the convex hull of the points that satisfy both the antecedent and consequent. Our result is then that every consistent formula without nested conditionals (...) is satisfiable in a model based on a finite set of points in the plane. The proof relies on a result by Richter and Rogers showing that every finite abstract convex geometry can be represented by convex polygons in the plane. (shrink)

I show the relevance of feminist thought to some of the major debates within the field of environmental ethics. The feminist vision of a holistic universe is contrasted with the dualistic notions inherent in both the “individual rights” and traditionally defined “holist” camps. I criticize the attempt in environmental ethics to establish universal, hierarchical rules of conduct for our dealing with nature (an up-down dualism) as weIl as the attempt to derive an ethic from reason alone (the dualism of reason (...) and emotion). I maintain that the division between the “holist” and “individual rights” camps is yet another form of dualist thinking, and propose in its stead a holistic vision that concerns itself both with the individual and with the whole of which the individual is apart.

In Nature Ethics: An Ecofeminist Perspective, Marti Kheel explores the underlying worldview of "nature ethics," offering an alternative ecofeminist approach. Seeking to heal the divisions between the seemingly disparate movements and philosophies of feminism, animal advocacy, environmental ethics, and holistic health, Kheel proposes an ecofeminist philosophy that underscores the importance of empathy and care for individual beings as well as larger wholes.

Estrechamente vinculado a su Historia de la Filosofía (Colección Fundamentos, números 21 y 22), esta Iniciación que nos ofrece ahora Felipe Martínez Marzoa refleja una considerable experiencia docente. No se trata, sin embargo, de un libro que se atenga a las normas de los programas oficiales, ni que pretenda exponer "un poco de todo" a costa de esquivar cuanto hay de dificultoso en un desarrollo, incluso elemental, de los temas de la Filosofía. El autor ha seleccionado premeditadamente una serie de (...) cuestiones básicas para una rigurosa lectura de iniciación -el silogismo y la proposición, el universal, la teoría de las ideas, las categorías, la esencia de las verdades matemáticas, la lógica simbólica, etc.- y las pone al alcance del lector que, deseando algo más que la familiarización con fórmulas definitorias, aspira a dar los primeros pasos en un terreno que no podrá recorrer nunca sin esfuerzo personal.
