In a recent paper Horsten embarked on a journey along the limits of the domain of the unknowable. Rather than knowability simpliciter, he considered a priori knowability, and by the latter he meant absolute provability, i.e. provability that is not relativized to a formal system. He presented an argument for the conclusion that it is not absolutely provable that there is a natural number of which it is true but absolutely unprovable that it has a certain property. The argument depends (...) on a description principle. I will argue that the latter principle implies the knowability of all arithmetical truths. Therefore, Horsten's argument is either sound but its conclusion is trivial, or his argument is unsound. (shrink)

I will examine three claims made by Ackerman and Kripke. First, they claim that not any arithmetical terms is eligible for universal instantiation and existential generalisation in doxastic or epistemic contexts. Second, Ackerman claims that Peano numerals are eligible for universal instantiation and existential generalisation in doxastic or epistemic contexts. Kripke's position is a bit more subtle. Third, they claim that the successor relation and the smaller-than relation must be effectively calculable. These three claims will be examined from the framework (...) of modal-epistemic arithmetic, i.e. arithmetic extended with certain modal, epistemic and modal-epistemic principles. I will present theorems that give support to the claims made by Ackerman and Kripke. (shrink)

The subject of the first section is Carnapian modal logic. One of the things I will do there is to prove that certain description principles, viz. the ''self-predication principles'', i.e. the principles according to which a descriptive term satisfies its own descriptive condition, are theorems and that others are not. The second section will be devoted to Carnapian modal arithmetic. I will prove that, if the arithmetical theory contains the standard weak principle of induction, modal truth collapses to truth. Then (...) I will propose a different formulation of Carnapian modal arithmetic and establish that it is free of collapse. Noteworthy is that one can retain the standard strong principle of induction. I will occupy myself in the third section with Carnapian epistemic logic and arithmetic. Here too it is claimed that the standard weak principle of induction is invalid and that the alternative principle is valid. In the fourth and last section I will get back to the self-predication principles and I will point to some of the consequences if one adds them to Carnapian Epistemic arithmetic. The interaction of self-predication principles and the strong principle of induction results in a collapse of de re knowability. (shrink)

Jan Heylen and Leon Horsten object to my proposed analysis of ordinary-language conditionals by appealing to certain putative counter-examples. In this reply, I explain how, by ignoring my reading of the indicative/subjunctive distinction, their objection misses its target. I also criticize their underlying methodology.

In Lowe (1995), instead of endorsing a Stalnaker/Lewis-style account of counterfactuals, E. J. Lowe claims that a variation of C. I. Lewis’s strict implication alone captures the essence of everyday conditionals and avoids the paradoxes of strict implication. However, Lowe’s approach fails to account for the validity of simple and straightforward arguments such as ‘if 2=3 then 2+1=3+1’, and Heylen & Horsten (2006) even claims that no variation of strict implication can successfully describe the logical behavior of natural language (...) conditionals. By incorporating the German logician O. Becker’s modal intuition with the insight of Ramsey’s Test, we show that there does exist a unified, strict-conditional based account of everyday conditionals, which withstands all attacks previously raised against truth-conditional accounts of conditionals. Furthermore, a subtle distinction between autistic and realistic readings of the indexical ‘I’ involved in a conditional helps us resolve a recent debate concerning the Thomason conditionals.

Thomas E. Hill, Jr., interprets and extends Kant's moral theory in a series of essays that highlight its relevance to contemporary ethics. He introduces the major themes of Kantian ethics and explores its practical application to questions about revolution, prison reform, and forcible interventions in other countries for humanitarian purposes.

The responses to the questions of why? when?, how?, where?, and in what ways? business ethics should be taught in the BusinessEthics classroom inundate the scholarly literature. Yet, to date, despite some very interesting ideas, with respect to the answers givento the above question, not only has nothing even close to consensus been reached, but this particular area of pedagogy is instagnation—authors still challenge both the very idea of teaching business ethics as well as the practical value of such courses (...) for ourstudents once they graduate to the corporate world.In this paper I will suggest that the reason for this lack of pedagogical progress is that there has been a serious oversight regarding the most important teaching question of all: Who? I will show that the pedagogical issue of whom should be teaching Business Ethics has been largely ignored, skirted or answered incorrectly. I will then boldly argue that the only necessary condition for successful courses inBusiness Ethics is that they be taught by experts in ethics, i.e., Ph.D.s in philosophy. (shrink)

In light of the development of “CRISPR” technology, new promising advances in therapeutic and preventive approaches have become a reality. However, with it came many ethical challenges. The most recent worldwide condemnation of the first use of CRISPR to genetically modify a human embryo is the latest example of ethically questionable use of this new and emerging field. Monotheistic religions are very conservative about such changes to the human genome and can be considered an interference with God’s creation. Moreover, these (...) changes could cause perpetual changes to future generations. The Muslim scholars establish their decisions by addressing five foundations of Islamic law i.e. “maqāṣid al sharı̄`a”; the purposes of the law. These are dın̄, nafs, nasl, `aql and māl. To achieve this, the five principles should all be met before approval of an experiment like the Chinese embryo modifications; Qaṣd which is achieved in this case as it aims to protect the embryo from HIV. Yaqın̄ and Ḍarar were not satisfied as they require strong scientific certainty of the procedures, and evidence of safety. Ḍarūra by which the alternatives being compared; in this case more established and proven safe alternatives to protect the HIV transmission from the father are available, so this principle is not met. The final principle is `Urf, by which the social context of using any contemporary technology should be taken in consideration, and clearly this was not achieved. Collectively, germline changes are rejected from an Islamic perspective until the five principles are fulfilled. In the Chinese Twins gene editing case, there was clearly no justification or support for it according to the Muslim Jurisprudence laws. These laws and approaches can serve as an ethical checklist for such controversial research, especially in early stages of the research. (shrink)

Kearns (2021) reconstructs Berkeley’s (1713) Master Argument as a formally valid argument against the Materialist Thesis, with the key premise the Distinct Conceivability Thesis, namely the thesis that truths about sensible objects having or lacking thinkable qualities are (distinctly) conceivable and as its conclusion that all sensible objects are conceived. It will be shown that Distinct Conceivability Thesis entails the Reduction Thesis, which states that de dicto propositional (ordinary or distinct) conceivability reduces to de re propositional (ordinary or distinct) conceivability. (...) While Kearns (2021) set out to avoid the confusion of a de re claim with a de dicto claim, which Prior (1955) accused Berkeley of, Kearns can be accused of making a similar conceptual confusion.

The path of those who would approach the study of Bentham's writings on Evidence has been considerably smoothed by the recent publication of William Twining's work on the evidence theories of Bentham and Wigmore. The material on evidence is now being tackled by the Bentham Project. It presents no easy task. The central core, The Rationale of Judicial Evidence, edited and published by John Stuart Mill in 1827, exists only in the printed version, the MSS from which Mill worked having (...) disappeared. But a substantial body of related material which survives has yet to be thoroughly investigated, though William Twining has made a gallant start. A new edition of the work hitherto known as ‘An Introductory View of the Rationale of Evidence’, first printed in full in the Bowring edition of the Works of Jeremy Bentham is in preparation. The first fruits of this endeavour is that the title of that work as it should appear in due course in the new Collected Works will be Introduction to the Rationale of Evidence: An Introductory View for the Use of Lawyers as well as Non-lawyers, the title in fact given to the work by Bentham. It is intended that what follows should similarly be of use to non-lawyers as well as lawyers. (shrink)

Soeurs ennemies ou soeurs jumelles, servante et maîtresse ou compagnes de labeur, s'ignorant l'une l'autre ou unies au point de presque s'identifier, la foi et la raison entretiennent à l'évidence une relation intense et tumultueuse. N'est-ce pas justement au coeur du mouvement qui tantôt les rapproche tantôt les oppose que s'ajuste leur rapport? Plus que d'un état stable acquis une fois pour toutes il s'agit bien d'une dynamique, d'un processus. C'est cc que visent à montrer les essais réunis dans cc (...) livre, qui rassemble les fruits d'un colloque de théologie et de philosophie tenu à l'initiative du Studium de Philosophie de Chartres et de l'Institut de Théologie des Dombes, centres de formation de la Communauté du Chemin Neuf.

Presenta a grandes rasgos su tesis doctoral. Dentro del marco de la teoría de los afectos, Spinoza sostiene una tesis sobre la alienación a partir de la imaginación y del tiempo, para ello produce una teoría del tiempo y, fundamentalmente, una teoría de las intensidades que sirve para explicar la ilusión.

Many philosophical discussions hinge on the concept of knowability. For example, there is a blooming literature on the so-called paradox of knowability. How to understand this notion, however? In this paper, we examine several approaches to the notion: the naive approach to take knowability as the possibility to know, the counterfactual approach endorsed by Edgington (1985) and Schlöder (2019) , approaches based on the notion of a capacity or ability to know (Fara 2010, Humphreys 2011), and finally, approaches that make (...) use of the resources of dynamic epistemic logic (van Benthem 2004, Holliday 2017).

In contemporary discussion of the philosophy of religion, or for that matter of any branch of philosophy, the names of Whitehead and Wittgenstein are not often linked. Whitehead's later work is, for the most part, treated as a rather specialized interest, an attractively under-cultivated field for the enterprising thesis-writer perhaps, but well away from the main centres of current philosophical activity. And what he has to say about specifically religious or theological issues 1 becomes simply one ramification of an ingenious (...) but somewhat eccentric system. Nonetheless, there is at least this much justification for considering it in relation to the much more influential and widely discussed views of Wittgenstein. Whitehead has some original things to say about God, Wittgenstein some original reasons for thinking that Whitehead's brand of originality is here radically misplaced. And the possibility or otherwise of such theological originality is an issue of very considerable importance for the philosophy of religion. (shrink)

Decisions related to animal welfare standards depend on farmer’s multiple goals and values and are constrained by a wide range of external and internal forces. The aim of this paper is twofold, i.e., to develop a theoretical framework for farmers’ AW decisions that incorporates farmers’ goals, use and non-use values and to present an approach to empirically implement the theoretical framework. The farmer as a head of the farm household makes choices regarding production to maximize the utility of the household. (...) The overall utility of the farmer is determined by his multiple objectives. For the analysis of multi-objective problems, the multiple criteria decision - making paradigm provides an appropriate theoretical framework. However, theories from the field of social-psychology are needed to facilitate the identification of all relevant aspects in the decision making. The practical use of the conceptual framework is demonstrated using a simple numerical application of a multi-objective programming model. Two workshops were devoted to examining the scientific consistency and the practical usefulness of the approach. Implementing this approach will increase knowledge of the main factors and barriers that determine farmers’ decisions with regard to AW standards. This knowledge is relevant during the development of new AW concepts that aims to supply products that comply with above-legal AW standards for middle-market segments. (shrink)

Appeal to experience for rational justification of religious belief is probably as old as the question whether religious belief has any rational support. The issues relevant to such appeal range widely, and I will have to be content to deal with only a few of them.

Context: Phenomenology and the enactive approach pose a unique challenge to dream research: during sleep one seems to be relatively disconnected from both world and body. Movement and perception, prerequisites for sensorimotor subjectivity, are restricted; the dreamer’s experience is turned inwards. In cognitive neurosciences, on the other hand, the generally accepted approach holds that dream formation is a direct result of neural activations in the absence of perception, and dreaming is often equated with “delusions.” Problem: Can enactivism and phenomenology account (...) for the variety of dream experiences? What kinds of experiential and empirical approaches are required in order to probe into dreaming subjectivity? Investigating qualities of perception, sensation, and embodiment in dreams, as well as the relationship between the dream-world and waking-world requires a step away from a delusional or altered-state framework of dream formation and a step toward an enactive integrative approach. Method: In this article, we will focus on the “depth” of dream experiences, i.e., what is possible in the dream state. Our article is divided into two parts: a theoretical framework for approaching dreaming from an enactive cognition standpoint; and discussion of the role and strategies for experimentation on dreaming. Based on phenomenology and theories of enactivism, we will argue for the primacy of subjectivity and imagination in the formation of lived experience. Results: We propose that neurophenomenology of dreaming is a nascent discipline that requires rethinking the relative role of third-, first- and second-person methodologies, and that a paradigm shift is required in order to investigate dreaming as a phenomenon on a continuum of conscious phenomena as opposed to a break from or an alteration of consciousness. Implications: Dream science, as part of the larger enterprise of consciousness and subjectivity studies, can be included in the enactive framework. This implies that dream experiences are neither passively lived nor functionally disconnected from dreamers’ world and body. We propose the basis and some concrete strategies for an empirical enactive neurophenomenology of dreaming. We conclude that investigating dream experiences can illuminate qualities of subjective perception and relation to the world, and thus challenge the traditional subject-object juxtaposition. Constructivist content: This article argues for an interdisciplinary enactive cognitive science approach to dream studies. (shrink)
