How do people imagine the possibilities in which an assertion would be true and the possibilities in which it would be false? We argue that the mental representation of the meanings of connectives, such as "and", "or", and "if", specify how to construct the true possibilities for simple assertions containing just a single connective. It follows that the false possibilities are constructed by inference from the true possibilities. We report converging evidence supporting this account from four experiments in which the (...) participants had to list the true and the false possibilities for various sorts of assertion. Their systematic errors, response times, and think-aloud protocols corroborated the theory's predictions. Not even true possibilities are immediately available for complex assertions containing two or more different connectives. The task of listing the true possibilities then becomes difficult, and the task of listing the false possibilities almost impossible. (shrink)

The concept of _substructural logic_ was originally introduced in relation to limitations of Gentzen’s structural rules of Contraction, Weakening and Exchange. Recent years have witnessed the development of substructural logics also challenging the Tarskian properties of Reflexivity and Transitivity of logical consequence. In this introduction we explain this recent development and two aspects in which it leads to a reassessment of the bounds of classical logic. On the one hand, standard ways of defining the notion of logical consequence in classical (...) logic naturally induce substructural logics when admitting more than two truth values; on the other hand, these substructural logics give rise to hierarchies of _metainferences_ that can be used to approximate classical logic at different levels.

The paper proposes with Davidson that the talk of metaontology is literally meaningless, but with Wittgenstein that it is so in a way that grants a unique type of insight. More specifically, it argues both that Davidson’s arguments have a cogency that is hard to dismiss, and also that, since his own arguments are metaontological, they are self-referential, and consequently in turn undermine their own meaning as well. The paper argues further that metaontological statements cannot be avoided. Consequently, this kind (...) of statement constitutes an unavoidable self-referential paradox that means what it also excludes as capable of meaning. The result is a reinstatement of the meaning of ontological insight and in fact, the paper argues, a deep enrichment and also a particularly cogent justification of it. In addition, the logical peculiarity of the paradox involved has further useful consequences for the outcome of this justification, including a mutually illuminating commonality with some versions of metaethics.

To reduce the otherwise high price of this scholarly, technical book of nearly 900 pages and make it more widely available beyond university libraries to individual readers, the non-profit publisher and the author have agreed to issue the printed edition at cost. ●●●●● The printed edition was released on September 1, 2021 and is now available through (...) all booksellers, including Barnes & Noble, Amazon, and brick-and-mortar bookstores under ISBN 978-0-578-88646-6. ●●●●● In light of the length of this book, readers who would like to have a more detailed description of the book's objectives and method may find it helpful to read the detailed and clearly written Wikipedia entry about this work: From the Wikipedia search page, use the search phrase "Critique of Impure Reason". At least at the time of this writing (11/29/2021), the Wikipedia entry is well-researched and accurate. ●●●●● In addition, a "Primer on Bartlett's CRITIQUE OF IMPURE REASON" has been made available by the author. It is available under its title through PhilPapers and other philosophy online archives. ●●●●● COMMENDATIONS OF THIS WORK, from the back cover of the published edition: ●●●●● “I admire its range of philosophical vision.” – Nicholas Rescher, Distinguished University Professor of Philosophy, University of Pittsburgh, author of more than 100 books. ●●●●● “Bartlett’s _Critique of Impure Reason_ is an impressive, bold, and ambitious work. Careful scholarship is balanced by original analyses that lead the reader to recognize the limits of meaning, knowledge, and conceptual possibility. The work addresses a host of traditional philosophical problems, among them the nature of space, time, causality, consciousness, the self, other minds, ontology, free will and determinism, and others. The book culminates in a fascinating and profound new understanding of relativity physics and quantum theory.” – Gerhard Preyer, Professor of Philosophy, Goethe-University, Frankfurt am Main, Germany, author of many books including _Concepts of Meaning_, _Beyond Semantics and Pragmatics_, _Intention and Practical Thought_, and _Contextualism in Philosophy_. ●●●●● “[This work’s] goal is of a unique and difficult species: Dr. Bartlett seeks to develop a formal logical calculus on the basis of transcendental philosophical arguments; in fact, he hopes that this calculus will be the formal expression of the transcendental foundation of knowledge.... I consider Dr. Bartlett’s work soundly conceived and executed with great skill.” – C. F. von Weizsäcker, philosopher and physicist, former Director, Max-Planck-Institute, Starnberg, Germany. ●●●●● “Bartlett has written an American “Prolegomena to All Future Metaphysics.” He aims rigorously to eliminate meaningless assertions, reach bedrock, and place philosophy on a firm foundation that will enable it, like science and mathematics, to produce lasting results that generations to come can build on. This is a great book, the fruit of a lifetime of research and reflection, and it deserves serious attention.” — Martin X. Moleski, former Professor, Canisius College, Buffalo, NY, studies of scientific method, the presuppositions of thought, and the self-referential nature of epistemology. ●●●●● “Bartlett has written a book on what might be called the underpinnings of philosophy. It has fascinating depth and breadth, and is all the more striking due to its unifying perspective based on the concepts of reference and self-reference.” – Don Perlis, Professor of Computer Science, University of Maryland, author of numerous publications on self-adjusting autonomous systems and philosophical issues concerning self-reference, mind, and consciousness. ●●●●● ●●●●● The _Critique of Impure Reason: Horizons of Possibility and Meaning_ comprises a major and important contribution to philosophy. Thanks to the generosity of its publisher, this massive 885-page volume has been published as a free open access eBook (3.75MB) as well as an open access printed edition. It inaugurates a revolutionary paradigm shift in philosophical thought by providing compelling and long-sought-for solutions to a wide range of philosophical problems. In the process, the work fundamentally transforms the way in which the concepts of reference, meaning, and possibility are understood. The book includes a Foreword by the celebrated German philosopher and physicist Carl Friedrich von Weizsäcker. ●●●●● In Kant’s _Critique of Pure Reason_ we find an analysis of the preconditions of experience and of knowledge. In contrast, but yet in parallel, the new _Critique_ focuses upon the ways—unfortunately very widespread and often unselfconsciously habitual—in which many of the concepts that we employ _conflict_ with the very preconditions of meaning and of knowledge. ●●●●● This is a book about the boundaries of frameworks and about the unrecognized conceptual confusions in which we become entangled when we attempt to transgress beyond the limits of the possible and meaningful. We tend either not to recognize or not to accept that we all-too-often attempt to trespass beyond the boundaries of the frameworks that make knowledge possible and the world meaningful. ●●●●● The _Critique of Impure Reason_ proposes a bold, ground-breaking, and startling thesis: that a great many of the major philosophical problems of the past can be solved through the recognition of a viciously deceptive form of thinking to which philosophers as well as non-philosophers commonly fall victim. For the first time, the book advances and justifies the criticism that a substantial number of the questions that have occupied philosophers fall into the category of “impure reason,” violating the very conditions of their possible meaningfulness. ●●●●● The purpose of the study is twofold: first, to enable us to recognize the boundaries of what is referentially forbidden—the limits beyond which reference becomes meaningless—and second, to avoid falling victims to a certain broad class of conceptual confusions that lie at the heart of many major philosophical problems. As a consequence, the boundaries of _possible meaning_ are determined. ●●●●● Bartlett, the author or editor of more than 20 books, is responsible for identifying this widespread and delusion-inducing variety of error, _metalogical projection_. It is a previously unrecognized and insidious form of erroneous thinking that undermines its own possibility of meaning. It comes about as a result of the pervasive human compulsion to seek to transcend the limits of possible reference and meaning. ●●●●● Based on original research and rigorous analysis combined with extensive scholarship, the _Critique of Impure Reason_ develops a self-validating method that makes it possible to recognize, correct, and eliminate this major and pervasive form of fallacious thinking. In so doing, the book provides at last provable and constructive solutions to a wide range of major philosophical problems. ●●●●● CONTENTS AT A GLANCE ▪▪▪▪▪ Preface ▪▪▪▪▪ Foreword by Carl Friedrich von Weizsäcker ▪▪▪▪▪ Acknowledgments ▪▪▪▪▪ Avant-propos: A philosopher’s rallying call ▪▪▪▪▪ Introduction ▪▪▪▪▪ A note to the reader ▪▪▪▪▪ A note on conventions ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART I ▪▪▪▪▪ ▪▪▪▪▪ WHY PHILOSOPHY HAS MADE NO PROGRESS AND HOW IT CAN ▪▪▪▪▪ 1 Philosophical-psychological prelude ▪▪▪▪▪ 2 Putting belief in its place: Its psychology and a needed polemic ▪▪▪▪▪ 3 Turning away from the linguistic turn: From theory of reference to metalogic of reference ▪▪▪▪▪ 4 The stepladder to maximum theoretical generality ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART II ▪▪▪▪▪ THE METALOGIC OF REFERENCE ▪▪▪▪▪ A New Approach to Deductive, Transcendental Philosophy ▪▪▪▪▪ 5 Reference, identity, and identification ▪▪▪▪▪ 6 Self-referential argument and the metalogic of reference ▪▪▪▪▪ 7 Possibility theory ▪▪▪▪▪ 8 Presupposition logic, reference, and identification ▪▪▪▪▪ 9 Transcendental argumentation and the metalogic of reference ▪▪▪▪▪ 10 Framework relativity ▪▪▪▪▪ 11 The metalogic of meaning ▪▪▪▪▪ 12 The problem of putative meaning and the logic of meaninglessness ▪▪▪▪▪ 13 Projection ▪▪▪▪▪ 14 Horizons ▪▪▪▪▪ 15 De-projection ▪▪▪▪▪ 16 Self-validation ▪▪▪▪▪ 17 Rationality: Rules of admissibility ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART III ▪▪▪▪▪ PHILOSOPHICAL APPLICATIONS OF THE METALOGIC OF REFERENCE ▪▪▪▪▪ Major Problems and Questions of Philosophy and the Philosophy of Science ▪▪▪▪▪ 18 Ontology and the metalogic of reference ▪▪▪▪▪ 19 Discovery or invention in general problem-solving, mathematics, and physics ▪▪▪▪▪ 20 The conceptually unreachable: “The far side” ▪▪▪▪▪ 21 The projections of the external world, things-in-themselves, other minds, realism, and idealism ▪▪▪▪▪ 22 The projections of time, space, and space-time ▪▪▪▪▪ 23 The projections of causality, determinism, and free will ▪▪▪▪▪ 24 Projections of the self and of solipsism ▪▪▪▪▪ 25 Non-relational, agentless reference and referential fields ▪▪▪▪▪ 26 Relativity physics as seen through the lens of the metalogic of reference ▪▪▪▪▪ 27 Quantum theory as seen through the lens of the metalogic of reference ▪▪▪▪▪ 28 Epistemological lessons learned from and applicable to relativity physics and quantum theory ▪▪▪▪▪ ▪▪▪▪▪ PART IV ▪▪▪▪▪ HORIZONS ▪▪▪▪▪ 29 Beyond belief ▪▪▪▪▪ 30 _Critique of Impure Reason_: Its results in retrospect ▪▪▪▪▪ ▪▪▪▪▪ SUPPLEMENT ▪▪▪▪▪ The Formal Structure of the Metalogic of Reference ▪▪▪▪▪ APPENDIX I ▪▪▪▪▪ The Concept of Horizon in the Work of Other Philosophers ▪▪▪▪▪ APPENDIX II ▪▪▪▪▪ Epistemological Intelligence ▪▪▪▪▪ References ▪▪▪▪▪ Index ▪▪▪▪▪ About the author.

Logical analysis is in Frege primarily not an analysis of a concept but of its sense. Five Fregean philosophical principles are presented as constituting a framework for a theory of logical or conceptual analysis, which I call analytical explication. These principles, scattered and sometime latent in his writings are operative in Frege's critique of other views and in his constructive development of his own view. The proposed conception of analytical explication is partially rooted in Frege's notion of analytical definition. It (...) may also be the basis of what is required of a reduction of one domain to another, if it is to have the philosophical significance many reductions allegedly have. (shrink)

Later Wittgenstein is famous for having related meaning and use. Nonetheless, thanks to Dummett and Kripke, and the debates they provoked, a conventional wisdom is nowadays available: Wittgenstein, so the story goes, adopted a theory of meaning in terms of assertability conditions. This paper claims that it is wrong to attribute such a theory to the Investigations. For such a thesis to go through, one of the following two scenarios should be confirmed. It should either be true that Wittgenstein reduces (...) all meaning-engendering uses and conditions of use to assertion and assertability conditions, or that he invokes assertability conditions to show that meaning is always use. But, I will be claiming, the first scenario is excluded by Wittgenstein’s thoughts about the role of assertion and his thoughts about the sense-force distinction, while the second scenario is excluded by Wittgenstein’s thoughts about truth.

That there are analytic truths may challenge a principle of the homogeneity of truth. Unlike standard conceptions, in which analyticity is couched in terms of "truth in virtue of meanings", Frege's notions of analytic and a priori concern justification, respecting a principle of the homogeneity of truth. Where there is no justification these notions do not apply, Frege insists. Basic truths and axioms may be analytic (or a priori), though unprovable, which means there is a form of justification which is (...) not (deductive) proof. This is also required for regarding singular factual propositions as a posteriori. A Fregean direction for explicating this wider notion of justification is suggested in terms of his notion of sense (Sinn)—modes in which what the axioms are about are given—and its general epistemological significance is sketched.

This paper is a contribution to a discussion in philosophy of technology by focusing on the epistemological status of the example. Of the various developments in the emerging, inchoate field of philosophy of technology, the “empirical turn” stands out as having left the most enduring mark on the trajectory contemporary research takes. From a historical point of view, the empirical turn can best be understood as a corrective to the overly “transcendentalizing” tendencies of “classical” philosophers of technology, such as Heidegger. (...) Empirically oriented philosophy of technology emphasizes actual technologies through case-study research into the formation of technical objects and systems (constructivist studies) and how they, for example, transform our perceptions and conceptions (the phenomenological tradition) or pass on and propagate relations of power (critical theory). This paper explores the point of convergence of classical and contemporary approaches by means of the notion of the “example” or “paradigm.” It starts with a discussion of the quintessential modern philosopher of technology, Martin Heidegger, and his thinking about technology in terms of the ontological difference. Heidegger’s framing of technology in terms of this difference places the weight of intelligibility entirely on the side of being, to such an extent that his examples become heuristic rather than constitutive. The second part of the paper discusses the methodological and epistemological import of the “example” and the form of intelligibility it affords. Drawing on the work of Wittgenstein (standard metre), Foucault (panopticism), and Agamben (paradigm), we argue that the example offers an alternative way of understanding the study of technologies from that of empirical case studies.

Can there be mathematical explanations of physical phenomena? In this paper, I suggest an affirmative answer to this question. I outline a strategy to reconstruct several typical examples of such explanations, and I show that they fit a common model. The model reveals that the role of mathematics is explicatory. Isolating this role may help to re-focus the current debate on the more specific question as to whether this explicatory role is, as proposed here, also an explanatory one.

Organization emerges as reality only through language. Transformation is such an emergence and it must get over the present context. A descriptive or implicative language fails to transcend the context. Linguistic suggestion of imageries and linguistic communion through imagination take departure from the present context and emerge as the new pleasurable transformed reality of organization. Linguistic holds the key to organizational transformation.

What is it to see a stove as world (als Welt) and why does the early Wittgenstein use such a curious example to describe what it means to see something as significant (bedeutend)? I argue that Wittgenstein's odd choice can be best understood in the light of a conceptual relation between value and semantic meaning. To that purpose, I draw attention to his use of the word Bedeutung to denote value, and to the direct connection he draws between seeing as (...) world and seeing with the whole logical space. To see a stove as bedeutend, I conclude, is to see it against the background of the propositional contexts in which a stove figures meaningfully. (shrink)

The ArgumentStarting from the thesis that a science constructs the knowledge of the part of the world allotted to it, the present paper aims at bringing together all the various aspects of physics under a unified conceptual framework — that provided by the Marxian concept “mode of production.” After an introduction providing the initial plausibility grounds for the undertaking, the concept is analyzed into its conceptual elements in Part I of the paper. The analysis presents the reconstruction initiated by Louis (...) Althusser and developed by his followers. Part II starts from a characterization of physical problems. This offers a basis for “reading” physics in the terms introduced in Part I. The rest of Part II is devoted to the identification of all the aspects of physics with the conceptual elements in question. The paper aims at three things: to uncover the connections holding among seemingly disparate aspects of physics, usually discussed in almost total independence from each other; to take full account of the social dimensions of physics without vindicating social constructivism; to show that the boundaries separating the disciplines of philosophy, history and sociology of science are more arbitrary than usually considered.

As is predictable, several comments raise issues about our characterization of relativism. We will focus on these first before discussing Paul Boghossian’s comm.

In explaining the notion of a fundamental property or relation, metaphysicians will often draw an analogy with languages. The fundamental properties and relations stand to reality as the primitive predicates and relations stand to a language: the smallest set of vocabulary God would need in order to write the “book of the world.” This paper attempts to make good on this metaphor. To that end, a modality is introduced that, put informally, stands to propositions as logical truth stands to sentences. (...) The resulting theory, formulated in higher-order logic, also vindicates the Humean idea that fundamental properties and relations are freely recombinable and a variant of the structural idea that propositions can be decomposed into their fundamental constituents via logical operations. Indeed, it is seen that, although these ideas are seemingly distinct, they are not independent, and fall out of a natural and general theory about the granularity of reality. (shrink)

This paper argues that the theory of structured propositions is not undermined by the Russell-Myhill paradox. I develop a theory of structured propositions in which the Russell-Myhill paradox doesn't arise: the theory does not involve ramification or compromises to the underlying logic, but rather rejects common assumptions, encoded in the notation of the $\lambda$-calculus, about what properties and relations can be built. I argue that the structuralist had independent reasons to reject these underlying assumptions. The theory is given both a (...) diagrammatic representation, and a logical representation in a novel language. In the latter half of the paper I turn to some technical questions concerning the treatment of quantification, and demonstrate various equivalences between the diagrammatic and logical representations, and a fragment of the $\lambda$-calculus.

Dasgupta :35–67, 2009) has argued that material individuals, such as particles and laptops, are metaphysically objectionable and must be eliminated from our fundamental theories of the world. He proposes to eliminate them by redescribing all the fundamental facts of the world in a variant of predicate functor logic. We study the status, on this theory, of a putative fact particularly recalcitrant to a formulation within predicate functor logic: his own claim that there are no fundamental or primitive material individuals. We (...) consider three regimentations of the denial of primitive individuals and show that—under some plausible hypotheses about fundamental truths and the fundamentality operator—they cannot be consistently translated in predicate functor logic by Dasgupta’s usual strategy. We conclude by discussing two approaches to salvage Generalism, in the absence of such a translation. (shrink)

All sides in the recent debates over the Quine‐Putnam Indispensability thesis presuppose Quine's criterion for determining what a discourse is ontologically committed to. I subject the criterion to scrutiny, especially in regard to the available competitor‐criteria, asking what means of evaluation there are for comparing alternative criteria against each other. Finding none, the paper concludes that ontological questions, in a certain sense, are philosophically indeterminate.

Some of the most interesting questions about Kant, and more particularly about his moral philosophy, arise when he is placed alongside the giants of antiquity. Where does he come together with Plato? Where with Aristotle? Where does he diverge from each? He comes together with Plato in a shared conception of Ideas. When he first outlines how he is using the term ‘Idea’ in the Critique of Pure Reason , he insists that he is using it in none other than (...) its original Platonic sense; and he explains away certain discrepancies with the comment: It is by no means unusual… to find that we understand [an author] better than he has understood himself. As he has not sufficiently determined his concept, he has sometimes spoken… in opposition to his own intention. (shrink)

Although philosophy has undergone a number of revolutions since the turn of the century, the existence of universals is still debated largely in the terms employed by Moore and Russell around 1910. A recent article by Alan Donagan illustrates this nicely, for Donagan expounds and defends what he takes to be the principal argument for universals given by Russell in The Problems of Philosophy. I shall comment critically on the case Donagan makes for Russell's metaphysical realism, but my main concern (...) is to establish a point of more general interest—namely, that the most plausible strategy for defending a commitment to universals actually raises more problems than it promises to solve.

At Oxford University, in the context of WW2, when men were largely obliged to abandon the university benches to take part in the war effort, four women philosophers, Iris Murdoch (1919-1999), Mary Midgley (1919-2018), Elizabeth Anscombe (1919-2001) and Philippa Foot (1920-2010), formed a group of philosophical reflections that would become a competitor, after the war, to John L. Austin’s famous ‘Saturday Mornings’. At the heart of the concerns of this ‘wartime quartet’: putting the importance of being human back at the (...) centre of ethics. They opposed “modern moral philosophy” and its many presuppositions, including the claim that ethical questions are independent of the facts of human life or concern a purely rational subject abstracted from everyday issues and from its belonging to the human species. By putting the importance of being human back at the heart of their ethical reflections, these philosophers came to reflect on issues that directly concern human life, far from the philosophical abstractions that interested their men homologues. In this paper, I explore the extent to which this re-inscription of philosophy into everyday life and into ordinary human concerns, opens the way to a feminist philosophy and ethics. (shrink)

This article addresses the question of the mechanisms of the emergence of structure and meaning in the biological and physical sciences. It proceeds from an examination of the concept of intentionality and proposes a model of intentional behavior on the basis of results of computer simulations of structural and functional self-organization. Current attempts to endow intuitive aspects of meaningful complexity with operational content are analyzed and the metaphor of DNA as a computer program (the `genetic program') is critically examined in (...) relation to an alternative metaphor of DNA as data. It is argued that relatively simple networks of boolean automata can classify and recognize patterns of binary strings on the basis of non-programmed, self-generated criteria, but lack a capacity for self-observation and interpretation. To overcome this problem it is necessary to clarify the relationships between the goals and underlying mechanisms of a process and between a system and its environment. It will be shown that memory devices that record the histories of interactions are essential for models of conscious and unconscious intentional behavior and that the possibility of infinitely sophisticated - and therefore unprogrammable - machines cannot be avoided. It will be argued that the notion of infinite sophistication allows the ideas of self-organization and physical determinism to be reconciled. These models will be used to suggest how the voluntary aspect of decision-making in general can emerge out of functional self-organizing processes. The conclusion will introduce the notion of `underdetermination' of theories, which imposes an intrinsic limitation on models of complex natural systems - a limitation that, at the same time, may be precisely what makes possible mutual understanding and intersubjectivity.

The idea that religious belief is ‘almost inevitable’ is so forcefully argued by Justin Barrett that it can warrant justifiable concern – especially since he claims atheism is an unnatural handicap. In this article, I argue that religious belief in Homo sapiens isn’t inevitable – and that Barrett does agree when pushed. I describe the role played by a Hyperactive Agency Detection Device in the generation of belief in God as necessary but insufficient in explaining religious culture – I distance (...) myself from some common conceptions of HADD and the view I take of it is unorthodox. I point out that the conclusion to Barrett’s book, ‘Why Would Anyone Believe in God?’ is a fine example of the very hyperactive agency detection Barrett himself describes, and is therefore highly suspect.

One of the motivations for the researches leaded by the members of Vienna Circle with regard to the foundations of scientific language is found on Wittgenstein’s “Tractatus Logico-Philophicus”. Even though there are divergences about the legitimacy of this influence, thebook was, in effect, taken as a theoretical motivation for the structuring of scientific language, developed by logical empiricists. This paper will present the theories developed by members of Vienna Circle emphasizing the elements presents in Tractatusthat were taken, largely, as influence (...) over the “criterion of meaning” of a philosophical proposition adopted by logical empiricists in an attempt to set a foundation for knowledge.

I want to defend a Combinatorialtheory of possibility. Such a view traces the very idea of possibility to the idea of the combinations – all the combinations which respect a certain simple form – of given, actual, elements. Combination is to be understood widely enough to cover the notions of expansion and contraction. The combinatorial idea is not new, of course. Wittgenstein gave a classical exposition of it in the Tractatus. Perhaps its charter is 3.4: ‘A proposition determines a place (...) in logical space. The existence of this logical place is guaranteed by the mere existence of the constituents’. There is a small additional combinatorial literature. I myself was converted to a combinatorial view by Brian Skyrms’ brief but fascinating article ‘Tractarian Nominalism.’. (shrink)

El objetivo del presente artículo es múltiple. Primero, pondera una serie de razones por las cuales la mística aún es relevante para el análisis de la condición humana del hombre actual. Segundo, propone a la promesa y a la ausencia como dispositivos de la mística. Tercero, expone, desde la lectura que hacen Alois Haas y Amador Vega de algunos sermones alemanes del Maestro Eckhart y de El peregrino querúbico de Angelus Silesius, los planteamientos fundamentales de la mística de estos autores, (...) a saber: el vaciamiento del alma, el coengendramiento, el abismo de Dios y la unión mística. Al mismo tiempo esboza cómo el pensamiento de Eckhart y Silesius, además de ser estudiado, produce ecos en algunas de las formulaciones filosóficas más importantes del siglo XX. The aim of this article is multiple. First, it weighs a series of reasons for which mysticism is still relevant for the analysis of man’s current human condition. Second, it proposes promise and absence as the devices of mysticism. Third, it exhibits, according to the reading of Alois Haas and Amador Vega of some of Meister Eckhart’s German sermons and Angelus Silesius’ The Cherubic Wanderer, the fundamental expositions of these authors’ mysticism, namely: voidance of the soul, co-conceivement, God’s abyss and mystical union. At the same time it outlines how the thought of Eckhart and Silesius, besides being studied, produces echoes in some of the most important philosophical formulations of the 20th century. (shrink)

Starting from the context in which Wittgenstein thinks of the concepts of “seeing-as” and “hearing-as”, the basic relation is clarified between the question of representation, musical understanding, and the theory of musical expressiveness. The points of views of Wollheim, Scruton, Levinson, and Ridley are discussed, in a re-consideration of the notions of hearing and understanding within Wittgenstein’s “last philosophy”.

The aim of this paper is to clarify why propositional logic is Post complete and its weak completeness was almost unnoticed by Hilbert and Bernays, while first-order logic is Post incomplete and its weak completeness was seen as an open problem by Hilbert and Ackermman. Thus, I will compare propositional and first-order logic in the Prinzipien der Mathematik, Bernays’s second Habilitationsschrift and the Grundzüge der Theoretischen Logik. The so called “arithmetical interpretation”, the conjunctive and disjunctive normal forms and the soundness (...) of the propositional rules of inference deserve special emphasis. (shrink)

This paper provides an overview of the origins, vicissitudes, and abandonment of ‘metapsychology’, the psycho-biological scientific core of the Freudian opus, and introduces the authors’ key revisions. Although couched in the language of metaphor and analogy from 19th century physics, the conceptual foundations of Freud’s theories contained the seeds of a bio-semiotic theory of mind and of human nature in the natural world. Its updated, modernized, version opens the door to an inter-penetrative epistemology leading to universal principles of logical form, (...) applicable to all types of vital inter-action. (shrink)

Claims (or the implicit assumption of the inherent worth of life) are pervasive and remain virtually unchallenged. I have already argued that these outright moral dictates are thinly veiled vestiges of theological ethics which, following the removal of their theological foundations, remain little more than nebulous claims supported only by fear of the consequences of a challenge. In my previous work, I rejected an a priori claim of an objective life’s worth, which is the worth that we should assign to (...) others’ lives, and elucidated a principled framework that gives rise to the said worth immediately, as a consequence of the experiences of its sentient environment. Herein, I address the complementary question of the value of one’s own life, which is the subjective value of life and, thus, Camus’s (in)famous view that “there is but one truly serious philosophical problem, and that is suicide”. As before, I rejected the inherency of a life’s worth, showing it to be contradictio in adjecto, and instead show how this worth too can in large part be seen to emerge from sentient experiences of the subject. Many of these are innately linked to experiences of other sentient beings as objects, thus erecting a framework that is both principled and thoroughly humane with Schopenhauer’s ‘loving kindness’ running through it. Practically, my framework illuminates an understanding of suicide as a real-world phenomenon, helping those who remain living to understand a deceased one’s decision, and paving the way to answering questions, such as when there should be an attempt to prevent suicide, and what means of suicide prevention are ethically permissible.

Philosophy Compass, Volume 17, Issue 7, July 2022.

The overall goal of this article is to show that aesthetics plays a major role in a debate at the very center of philosophy. Drawing on the work of David Bell, the article spells out how Kant and Wittgenstein use reflective judgment, epitomized by a judgment of beauty, as a key in their respective solutions to the rule-following problem they share. The more specific goal is to offer a Kantian account of semantic normativity as understood by Wittgenstein. The article argues (...) that Wittgenstein's reason for describing language as a collection of language games is to allow for a perspective that shows those games as internally purposive without any extralinguistic purpose. This perspective also allows for that union of the general rule and its particular application in practice that the original paradox of rule-following is wanting. (shrink)

Personal reflections on the philosophical career of Henry Johnstone, B.S. Haverford College, 1942, and Ph.D. Harvard, 1950, professor at Williams College 1948-1952 and Pennsylvania State University, 1952 - 2000.

The focus is on his efforts to resolve problems stemming from the conflict between the logical empiricism Johnstone embraced in his dissertation, and the arguments of his absolute idealist (...) colleagues at Williams, efforts he pursued in Philosophy and Argument (1959), and Validity and Rhetoric in Philosophical Argument (1978).

In sections 18 and 73 of Carnap’s Logical Syntax of Language , Carnap famously presents what he understands to be decisive objections to Wittgenstein’s Tractarian distinction between saying and showing. However, Carnap has been criticized in recent literature for severely misinterpreting that distinction. Against this criticism it is argued that Carnap reads that distinction as applying to two distinct classes of expressions ( Unsinn and sinnlos ) that he holds to emerge from his reading of Tractatus 4.1212 and related Tractarian (...) theses. It is then argued that Carnap’s counterexamples to Wittgenstein’s theses are successful given his reading, and that our analysis of his counterexamples puts us in a unique position to reevaluate his conventionalism.

Suele entenderse la Filosofía como el desarrollo de problemas guiados por un método que el autor del texto propone, siendo este generalmente un método racional. Pero la propuesta que aquí se hace es que los textos capitales de Miguel de Unamuno se configuran como una estrategia, para que el lector se implique con el autor en problemas y métodos que deben comprenderse en claves distintas a los usuales. Los textos de Unamuno entienden la tarea del lector como condición de posibilidad (...) para su propia comprensión. Y en este sentido necesitan al lector. Pero el tipo de lector que requiere no es un lector científico sino un lector mitológico. Mostrar esta propuesta, en la lectura Del sentimiento trágico de la vida, es lo que me propongo en este trabajo. (shrink)

The object of this paper is to throw light on the reciprocal exchanges between legal philosophy and the theory of speech acts (as developed by Austin and Searle). The first part concerns the contributions to legal philosophy made by the theory of speech acts with a view to developing new perspectives. The second part deals with the contributions of legal philosophy to speech act theory.

So-called evolutionary error theorists, such as Michael Ruse and Richard Joyce, have argued that naturalistic accounts of the moral sentiments lead us to adopt an error theory approach to morality. Roughly, the argument is that an appreciation of the etiology of those sentiments undermines any reason to think that they track moral truth and, furthermore, undermines any reason to think that moral truth actually exists. I argue that this approach offers us a false dichotomy between error theory and some form (...) of moral realism. While accepting the presuppositions of the evolutionary error theorist, I argue that contract-based approaches to morality can be sensitive to those presuppositions while still vindicating morality. Invoking Stephen Darwall’s distinction between contractualism and contractarianism, I go on to offer an evolutionary-based contractarianism. (shrink)

Philosophy has four forms: wonder, faith, doubt and scepticism. These are not separate categories, but separate ideal possibilities. Modern academic philosophy has fallen, for several centuries, into an error: which is the error of supposing that philosophy is only what I call doubt. Philosophy may be doubt: indeed, it is part of my argument that this is undeniably one element of, or one possibility in, philosophy; but doubt is only one of four points of the compass. In this essay I (...) indicate the nature of each point of the compass as it has been found in the history of philosophy. (shrink)

What we observe, through our usually limited lens, is that differential growing of space determines forms -characterized by their shape, size and coloration. As non-Euclidean geometrical mathematics have proclaimed: forms are manifestations of the curvature of space. Physics and other natural laws impose mathematical structural restrictions to biological forms. The molecules comprising any living form become arranged in specific ways in response to physical forces as well as chemical and biochemical conditions. Over time, such forms inherit additional historical restrictions that (...) make up their meaning, their semiotics. Color does not escape from this orthogenic reality. In this study, we present the colored pattern of the connexivum of Triatoma maculata, an insect vector of the etiologic agent of Chagas disease. This model is used as an example to appreciate mimicry under a heterodox and provocative approach. We unveil that beyond 1) mathematical and 2) historical semiotic restrictions of T. maculata mimesis of a yellowish-black alternating pattern, there are also 3) artistic interpretations; where metaphysics of life, beyond human perspective, is included.

It has been commonplace to maintain of the phenomenon that occurred during classical times, the change from relying on myth to trusting in reason: (1) that the emergence of philosophy from myth was marked by an abrupt discontinuity; (2) that mythical thinking was left behind once philosophy was invented or discovered; and (3) that the ancient Greeks were the agents of this miracle. This paper suggests that the so-called “Greek miracle” was, in fact, a miracle manqué and, more importantly, that (...) close examination of this failed miracle offers valuable insight into the philosophical crisis facing the world today.
