Embodied theories of grounded semantics postulate that, when word meaning is first acquired, a link is established between symbol and corresponding semantic information present in modality-specific—including primary—sensorimotor cortices of the brain. Direct experimental evidence documenting the emergence of such a link, however, is still missing. Here, we present new neuroimaging results that provide such evidence. We taught participants aspects of the referential meaning of previously unknown, senseless novel spoken words by associating them with either a familiar action or a familiar (...) object. After training, we used functional magnetic resonance imaging to analyze the participants’ brain responses to the new speech items. We found that hearing the newly learnt object-related word sounds selectively triggered activity in the primary visual cortex, as well as secondary and higher visual areas.These results for the first time directly document the formation of a link between the novel, previously meaningless spoken items and corresponding semantic information in primary sensory areas in a category-specific manner, providing experimental support for perceptual accounts of word-meaning acquisition in the brain.

In this text, a variety of modal logics at the sentential, first-order, and second-order levels are developed with clarity, precision and philosophical insight.

The concept of mass is one of the most fundamental notions in physics, comparable in importance only to those of space and time. But in contrast to the latter, which are the subject of innumerable physical and philosophical studies, the concept of mass has been but rarely investigated. Here Max Jammer, a leading philosopher and historian of physics, provides a concise but comprehensive, coherent, and self-contained study of the concept of mass as it is defined, interpreted, and applied in contemporary (...) physics and as it is critically examined in the modern philosophy of science. With its focus on theories proposed after the mid-1950s, the book is the first of its kind, covering the most recent experimental and theoretical investigations into the nature of mass and its role in modern physics, from the realm of elementary particles to the cosmology of galaxies.The book begins with an analysis of the persistent difficulties of defining inertial mass in a noncircular manner and discusses the related question of whether mass is an observational or a theoretical concept. It then studies the notion of mass in special relativity and the delicate problem of whether the relativistic rest mass is the only legitimate notion of mass and whether it is identical with the classical mass. This is followed by a critical analysis of the different derivations of the famous mass-energy relationship E = mc2 and its conflicting interpretations. Jammer then devotes a chapter to the distinction between inertial and gravitational mass and to the various versions of the so-called equivalence principle with which Newton initiated his Principia but which also became the starting point of Einstein's general relativity, which supersedes Newtonian physics. The book concludes with a presentation of recently proposed global and local dynamical theories of the origin and nature of mass.Destined to become a much-consulted reference for philosophers and physicists, this book is also written for the nonprofessional general reader interested in the foundations of physics.

We introduce a family of local ranks $D_Q$ depending on a finite set Q of pairs of the form $(\varphi (x,y),q(y)),$ where $\varphi (x,y)$ is a formula and $q(y)$ is a global type. We prove that in any NSOP $_1$ theory these ranks satisfy some desirable properties; in particular, $D_Q(x=x)<\omega $ for any finite tuple of variables x and any Q, if $q\supseteq p$ is a Kim-forking extension of types, then $D_Q(q) (...) Kim-non-forking extension, then $D_Q(q)=D_Q(p)$ for every Q that involves only invariant types whose Morley powers are -stationary. We give natural examples of families of invariant types satisfying this property in some NSOP $_1$ theories.We also answer a question of Granger about equivalence of dividing and dividing finitely in the theory $T_\infty $ of vector spaces with a generic bilinear form. We conclude that forking equals dividing in $T_\infty $, strengthening an earlier observation that $T_\infty $ satisfies the existence axiom for forking independence.Finally, we slightly modify our definitions and go beyond NSOP $_1$ to find out that our local ranks are bounded by the well-known ranks: the inp-rank (burden), and hence, in particular, by the dp-rank. Therefore, our local ranks are finite provided that the dp-rank is finite, for example, if T is dp-minimal. Hence, our notion of rank identifies a non-trivial class of theories containing all NSOP $_1$ and NTP $_2$ theories. (shrink)

Engaging with Kant’s transcendental logic seems to be a question of mere scholarly historical interest today. It is most commonly regarded a mixture between logic and psychology or epistemology, and by that, not a serious form of logic. Transcendental logic seems to be of no systematical impact on the concept of logic. My paper aims to disclose a different account on the endeavour of Kant’s transcendental logic in particular and of the “Critique of Pure Reason” (CPR) in general. Kant’s fundamental (...) question is in a revolutionary way aiming to ground the character of necessity of knowledge, which means to justify the claim that thinking in accordance with the forms and principles of formal logic does not lead to sheer tautologies or an unsolved contradiction, but to knowledge that is objectively valid. In a first part, I shall demonstrate the necessity and the significance of this new fundamental question of the CPR with respect to its genesis out of pre-Kantian metaphysics. A brief outline of Kant’s answer to this question, with special emphasis on his revolutionary new comprehension of logical form, will be given as well. A second part shall open up a perspective that lies beyond Kant’s standpoint with reference to Nietzsche and eventually to Hegel. I will answer the question: What knowledge do we achieve about being or actuality by means of formal logic? I will argue that Kant shows that formal logic is the logic of all technical-practical conduct but also, at least indirectly, the limitation of the technical-practical knowledge and its legitimate sphere of application.

Max Scheler’s essay on virtue, first published under a pseudonym in 1913, begins with some reflection upon the decline in his era of a concern for virtue. Its central theme is a phenomenological exhibition of the Christian experience of humility, reverence, and related concepts, together with an exploration of their historical and social embodiments in Western culture. The core of humility is a spiritual readiness to serve, related to love, that produces in its possessor a liberation from the ego. The (...) core of reverence is its sense of what surpasses our vision. It has the power to reveal to us the deeper value and being in all things. The paper contains elements of a polemic directed against scientific naturalism. (shrink)

Structural brain preservation (SBP) and classical cryonics are techniques aimed at preserving the human brain for potential future applications. Reluctant public discourse around these techniques may be explained with intuitive aversions identified by moral psychology. In the first part of the paper, we conjecture the existence of a self-sustaining cycle of moral condemnation of SBP and classical cryonics due to quick, affect-laden moral intuitions. In the second part, we propose an alternative framing of SBP and classical cryonics through a thought (...) experiment featuring a time machine metaphor called "Schrödinger’s chrono-cat", which might avoid triggering aversive moral intuitions and foster public discourse. We discuss the limitations of this framing and its consequences. (shrink)

À l'encontre de la conception classique qui fait de l'idée d'infini l'expression de la perfection de Dieu inscrite en l'homme, Diderot propose une conception de l'infini qui rapporte immédiatement celui-ci à sa production corporelle. Soustrayant ainsi l'infini au divin, la pensée du corps sensible révoque jusqu'en ses fondements la conceptualité classique qui, par la notion d'ordre, liait l'épistémologie au théologique. Le désordre s'en trouve réévalué jusqu'en ses formes pathologiques et gagne ainsi une valeur créatrice immanente et fondamentale.

Influenciados pelas discussões desenvolvidas por Álvaro Nascimento no artigo Trabalhadores Negros e o “Paradigma da Ausência”: contribuições à história social do trabalho no Brasil, pensamos este trabalho, cujo objetivo é analisar a instrumentalização da identidade negra nas estratégias argumentativas do Partido Comunista Brasileiro, das Ligas Camponesas e da Igreja Católica, forças que atuaram no campo brasileiro entre 1945 e 1964. Para tanto, consultamos um conjunto diversificado de periódicos e dialogamos com produções de diferentes centros de pesquisa.

This anthology includes 42 selections from a wide variety of cultural backgrounds and historical periods. The text is not limited to Western material; it also includes Native American, African-American, Hispanic and feminist selections. While quite diverse historically and culturally, the readings are chosen for their readability and philosophical significance. To facilitate incorporation into existing courses, the selections are arranged in six chapters that correspond to traditional philosophical categories: self identity, knowledge and truth, creation and reality, ethics, politics and religion.
