There is considerable evidence that listeners’ understanding of a spoken sentence need not always follow from a full analysis of the words and syntax of the utterance. Rather, listeners may instead conduct a superficial analysis, sampling some words and using presumed plausibility to arrive at an understanding of the sentence meaning. Because this latter strategy occurs more often for sentences with complex syntax that place a heavier processing burden on the listener than sentences with simpler syntax, shallow processing may represent (...) a resource conserving strategy reflected in reduced processing effort. This factor may be even more important for older adults who as a group are known to have more limited working memory resources. In the present experiment, 40 older adults and 20 younger adults were tested for comprehension of plausible and implausible sentences with a simpler subject-relative embedded clause structure or a more complex object-relative embedded clause structure. Dilation of the pupil of the eye was recorded as an index of processing effort. Results confirmed greater comprehension accuracy for plausible than implausible sentences, and for sentences with simpler than more complex syntax, with both effects amplified for the older adults. Analysis of peak pupil dilations for implausible sentences revealed a complex three-way interaction between age, syntactic complexity, and plausibility. Results are discussed in terms of models of sentence comprehension, and pupillometry as an index of intentional task engagement. (shrink)

We discuss the principles for a primitive, object-linguistic notion of consequence proposed by ) that yield a version of Curry’s paradox. We propose and study several strategies to weaken these principles and overcome paradox: all these strategies are based on the intuition that the object-linguistic consequence predicate internalizes whichever meta-linguistic notion of consequence we accept in the first place. To these solutions will correspond different conceptions of consequence. In one possible reading of these principles, they give rise to a notion (...) of logical consequence: we study the corresponding theory of validity by showing that it is conservative over a wide range of base theories: this result is achieved via a well-behaved form of local reduction. The theory of logical consequence is based on a restriction of the introduction rule for the consequence predicate. To unrestrictedly maintain this principle, we develop a conception of object-linguistic consequence, which we call grounded consequence, that displays a restriction of the structural rule of reflexivity. This construction is obtained by generalizing Saul Kripke’s inductive theory of truth. Grounded validity will be shown to satisfy several desirable principles for a naïve, self-applicable notion of consequence. (shrink)

Based on key texts of Derrida as well as his interviews and recently published seminars the article presents a “micrological” analysis of deconstructivist thought in the context of its appeal to phenomenology of Husserl and fundamental ontology of Heidegger. Derrida begins his intellectual path with a reflection on the most important topics of Husserlian phenomenology and discovers in the descriptions of temporalization a paradoxical movement of the immanent self-deconstruction of phenomenology. It from within undermines its own basic principle of the (...) primordial givenness of the living present to itself in its whole presence. From the point of view of Derrida’s deconstruction, the living present of self-presence of the transcendental ego, like itself, is no longer the original source of sense, meaning, knowledge and experience but rather the effect of difference. Derrida discovers the radical constitutive dependence of the present on the trace of the inevitably lost past, thus, his thought resolutely destroys the primordial nature of the present and roots it in the true “origin” as a game of delays and differences. Similarly, Derrida criticizes the project of fundamental ontology. While Heidegger conceives of the ontological difference between being and Being as the last hidden basis of any question in the discourse of metaphysics, Derrida insists that this differentiation is derived from différance as an even more primordial movement of difference. And although Derrida claims to have a more essential comprehension of the core of metaphysics compared to Husserl and Heidegger and even confidently classifies their philosophical work ones to the field of metaphysics, he continues to use the resources of phenomenological and transcendental discourse again and again, leaving them without any criticism. The most telling example here is the use of the phrase “always already” (toujours déjà, immer schon), incredibly common in the works of Heidegger and Husserl (as well as most other most famous modern phenomenologists) and accompanying most of Derrida’s texts. In this article we seek to draw attention to the mystery power of this phrase, which hides the secret of the origins of phenomenological, fundamental-ontological, transcendental, and deconstructivist discourses as such, and also to demonstrate the possibilities of self-deconstruction of deconstruction, which with new urgency returns us to the problem of defining the limits of metaphysics and the “margins of philosophy”.

Based on the philosophy of Martin Heidegger the article presents the possibility of actualizing Heidegger’s main question about the meaning of Being in the context of the analysis of so-called “a priori perfect.” During the development of fundamental ontology in the second half of the 1920s, Heidegger ponders the approach to Being in the history of philosophy and identifies such a feature of Being as a priori, a kind of antecedence of Being in relation to being. Although tradition invariably understands (...) Being in this way, in it, according to Heidegger, the question is no longer raised either about the sense of such antecedence, or about the temporal basis of this sense, and therefore a priori as the essential character of Being is left in total oblivion. We suggest that it is the problematization of apriority in its temporal origin that can contribute to resolving Heidegger’s fundamental philosophical question of time as the transcendental horizon of any concept of Being that precedes being. In this precedence there is a cherished temporal moment, the comprehension of which allows us to develop the “basic question of metaphysics” about the relationship of Being and time in a more concrete way than Heidegger’s four main themes of the question of Being: the ontological difference; the basic articulation of Being ); the truth-character of Being; the possible modifications of Being and the unity of Being’s variety. Revealing a priori question as the central question of all Heideggers thinking before the “Turn” we attempt to update this question and justify the need for its renewal on the basis of a fundamental ontology. With this task we relate the question of the essence of philosophy in general in its existential-temporal concept since philosophy appears as a temporality-based possible of the questioning return to the “earlier”: to the essential structures of being, knowledge, Being, Dasein. Our analysis is based on the following decisions: Being in relation to being is always pre-understood as “earlier,” and in this understanding a temporal definition operates, hence the main question of fundamental ontology about the relation of Being and time can be developed or at least clarified through the problem of meaning of a priori. The question of the meaning of the “earlier” and of the temporal basis for understanding Being as “earlier,” a priori, is concretized into the question of the conditions for the possibility of any ontology, including the fundamental ontology, which raises the question of the earlier in relation to Being and therefore “lives” in the light of the understanding of the “earlier” as such. This reflexive foundation of the fundamental ontology from itself is a necessary stage on the way of developing its project, if we remember that the main “duty” of the philosopher is to clarify “our inner nature” for the sake of opening the boundaries and conditions of the possibility of philosophy. The conclusion is that the possibilities of fundamental ontology in making sense of Being, time, and philosophy in general are far from exhausted, but await the questions that actualize them and new readings that allow to see the hidden richness of Heidegger’s thought.

We study the relationships between two clusters of axiomatizations of Kripke’s fixed-point models for languages containing a self-applicable truth predicate. The first cluster is represented by what we will call ‘\-like’ theories, originating in recent work by Halbach and Horsten, whose axioms and rules are all valid in fixed-point models; the second by ‘\-like’ theories first introduced by Solomon Feferman, that lose this property but reflect the classicality of the metatheory in which Kripke’s construction is carried out. We show that (...) to any natural system in one cluster—corresponding to natural variations on induction schemata—there is a corresponding system in the other proving the same sentences true, addressing a problem left open by Halbach and Horsten and accomplishing a suitably modified version of the project sketched by Reinhardt aiming at an instrumental reading of classical theories of self-applicable truth.

RésuméL'idée d'un “monde des images” situé quelque part entre les mondes immatériel et matériel est un pivot de la spéculation eschatologique dans l'Islam médiéval tardif. Comme cela a déjà été reconnu, le concept a été inauguré par al-Suhrawardī. Cependant, ses fondements plus proprement philosophiques et en particulier la notion d'images “suspendues” – des images dotées d'un statut en quelque manière objectif plutôt que purement mental ou subjectif – méritent d’être davantage clarifiés; et c'est ce que cet article entend faire. Puisque (...) le concept de “formes suspendues”, tout en étant appliqué par al-Suhrawardī à des questions eschatologiques dans le dernier traité de sa Philosophie de l'illumination, apparaît pour la première fois dans une discussion sur la vision spéculaire, j'examine assez en détail la conception avicennienne de la vision spéculaire telle qu'elle est présentée dans le Shifāʾ, ouvrage contre lequel al-Suhrawardī réagit. J'entreprends ensuite une reconstruction détaillée de deux paragraphes de la Philosophie de l'illumination en accordant une attention particulière à la question du statut ontologique des images “suspendues” ou “auto-subsistantes” ainsi qu’à l'idée selon laquelle les miroirs servent non pas de lieux dans lesquels les images résideraient, mais de lieux où elles deviennent manifestes.

Substructural logics and their application to logical and semantic paradoxes have been extensively studied. In the paper, we study theories of naïve consequence and truth based on a non-reflexive logic. We start by investigating the semantics and the proof-theory of a system based on schematic rules for object-linguistic consequence. We then develop a fully compositional theory of truth and consequence in our non-reflexive framework.

According to the implicit commitment thesis, once accepting a mathematical formal system S, one is implicitly committed to additional resources not immediately available in S. Traditionally, this thesis has been understood as entailing that, in accepting S, we are bound to accept reflection principles for S and therefore claims in the language of S that are not derivable in S itself. It has recently become clear, however, that such reading of the implicit commitment thesis cannot be compatible with well-established positions (...) in the foundations of mathematics which consider a specific theory S as self-justifying and doubt the legitimacy of any principle that is not derivable in S: examples are Tait’s finitism and the role played in it by Primitive Recursive Arithmetic, Isaacson’s thesis and Peano Arithmetic, Nelson’s ultrafinitism and sub-exponential arithmetical systems. This casts doubts on the very adequacy of the implicit commitment thesis for arithmetical theories. In the paper we show that such foundational standpoints are nonetheless compatible with the implicit commitment thesis. We also show that they can even be compatible with genuine soundness extensions of S with suitable form of reflection. The analysis we propose is as follows: when accepting a system S, we are bound to accept a fixed set of principles extending S and expressing minimal soundness requirements for S, such as the fact that the non-logical axioms of S are true. We call this invariant component the semantic core of implicit commitment. But there is also a variable component of implicit commitment that crucially depends on the justification given for our acceptance of S in which, for instance, may or may not appear reflection principles for S. We claim that the proposed framework regulates in a natural and uniform way our acceptance of different arithmetical theories. (shrink)

As a response to the semantic and logical paradoxes, theorists often reject some principles of classical logic. However, classical logic is entangled with mathematics, and giving up mathematics is too high a price to pay, even for nonclassical theorists. The so-called recapture theorems come to the rescue. When reasoning with concepts such as truth/class membership/property instantiation, (These are examples of concepts that are taken to satisfy naive rules such as the naive truth schema and naive comprehension, and that therefore are (...) compatible with a solution to paradox cast in the logics considered below. Other notions of similar kind can be added to the list.) if one is interested in consequences of the theory that only contain mathematical vocabulary, nothing is lost by reasoning in the nonclassical framework. This article shows that this claim is highly misleading, if not simply false. Under natural assumptions, some well-established approaches to recapture are incorrect. (shrink)

Nicolai Bachman explores the key principles and concepts of yoga philosophy through the Yoga Sutras offering an opportunity to learn and practice the sutras in Sanskrit, revealing the essence of yoga philosophy. The Yoga Sutras is a comprehensive and modern approach to working with Patanjali's seminal text for guidance and inspiration on your own journey toward clarity and happiness.

We determine the modal logic of fixed-point models of truth and their axiomatizations by Solomon Feferman via Solovay-style completeness results. Given a fixed-point model $\mathcal {M}$, or an axiomatization S thereof, we find a modal logic M such that a modal sentence $\varphi $ is a theorem of M if and only if the sentence $\varphi ^*$ obtained by translating the modal operator with the truth predicate is true in $\mathcal {M}$ or a theorem of S under all such translations. (...) To this end, we introduce a novel version of possible worlds semantics featuring both classical and nonclassical worlds and establish the completeness of a family of noncongruent modal logics whose internal logic is nonclassical with respect to this semantics.

From a different perspective, “essential actuality” is related to logical actuality. It means plain existence in the ideal sphere of being. One is familiar with this, for example, in “mathematical existence.” This does not merge with validity, but implies ...

This essay reviews two recent volumes containing editions of important early quranic codices. One of these is the so-called Sanaa Palimpsest, whose lower text at present remains our only known material witness to a recension of the quranic text that is different from the canonical one; the other is the Codex Amrensis. The essay devotes particular attention to the question of the textual relationship between the Quran’s standard text and that documented by the lower layer of the Sanaa Palimpsest, and (...) to Asma Hilali’s claim that the Sanaa Palimpsest never constituted a full quranic codex but only “a collection of disparate leaves.”.

It is no exaggeration to say that of the early 20th century German philosophers who claimed to establish a new ontology, former neo-Kantian turned realist Nicolai Hartmann is the only one to have actually followed through. "Ontology: Laying the Foundations" deals with "what is insofar as it is," and its four parts tackle traditional ontological assumptions and prejudices and traditional categories such as substance, thing, individual, whole, object, and phenomenon; a novel redefinition of existence and essence in terms of (...) the ontological factors Dasein and Sosein and their interrelations; an analysis of modes of "givenness" and the ontological embeddedness of cognition in affective transcendent acts; and a discussion of the status of ideal being, including mathematical being, phenomenological essences, logical laws, values, and the interconnections between the ideal and real spheres. Hartmann’s work offers rich resources for those interested in overcoming the human-centeredness of much 20th century philosophy.

Truth-theoretic deflationism holds that truth is simple, and yet that it can fulfil many useful logico-linguistic roles. Deflationism focuses on axioms for truth: there is no reduction of the notion of truth to more fundamental ones such as sets or higher-order quantifiers. In this paper I argue that the fundamental properties of reasonable, primitive truth predicates are at odds with the core tenets of classical truth-theoretic deflationism that I call fix, express, and quantify. Truth may be regarded as a broadly (...) logical, sui generis notion. However, this has little to do with the original aims of the deflationary theory of truth. (shrink)

In his 2023 AJOB article, Jorge Fabiano claims that a safety framework is needed to guard against the potential negative consequences of moral enhancement. He describes prudential desiderata that constitute the nodes of his proposed safety framework, ultimately arguing that a virtue theory, as opposed to a non-virtue based theory such as a consequentialist or deontological theory, hues closest to these desiderata. In this open peer commentary (OPC), I argue that Fabiano's trait-based analysis of enhancement-related changes, while illuminating, necessarily commits (...) us to a virtue theoretical framework.
