This paper has a two-fold objective: to provide a balanced, multi-faceted account of the origins of logicism; to rehabilitate Richard Dedekind as a main logicist. Logicism should be seen as more deeply rooted in the development of modern mathematics than typically assumed, and this becomes evident by reconsidering Dedekind's writings in relation to Frege's. Especially in its Dedekindian and Fregean versions, logicism constitutes the culmination of the rise of ?pure mathematics? in the nineteenth century; and this rise brought with it (...) an inter-weaving of methodological and epistemological considerations. The latter aspect illustrates how philosophical concerns can grow out of mathematical practice, as opposed to being imposed on it from outside. It also sheds new light on the legacy and the lasting significance of logicism today. (shrink)

Gottlob Frege and Ludwig Wittgenstein (the later Wittgenstein) are often seen as polar opposites with respect to their fundamental philosophical outlooks: Frege as a paradigmatic "realist", Wittgenstein as a paradigmatic "anti-realist". This opposition is supposed to find its clearest expression with respect to mathematics: Frege is seen as the "arch-platonist", Wittgenstein as some sort of "radical anti-platonist". Furthermore, seeing them as such fits nicely with a widely shared view about their relation: the later Wittgenstein is supposed to have developed his (...) ideas in direct opposition to Frege. The purpose of this paper is to challenge these standard assumptions. I will argue that Frege's and Wittgenstein's basic outlooks have something crucial in common; and I will argue that this is the result of the positive influence Frege had on Wittgenstein. (shrink)

In Frege's writings, the notions of truth, judgment, and objectivity are all prominent and important. This paper explores the close connections between them, together with their ties to further cognate notions, such as those of thought, assertion, inference, logical law, and reason. It is argued that, according to Frege, these notions can only be understood properly together, in their inter-relations. Along the way, interpretations of some especially cryptic Fregean remarks, about objectivity, laws of truth, and reason, are offered, and seemingly (...) opposed "realist" and "idealist" strands in his position reconciled.

The philosophy of mathematics has long been an important part of philosophy in the analytic tradition, ever since the pioneering works of Frege and Russell. Richard Dedekind was roughly Frege's contemporary, and his contributions to the foundations of mathematics are widely acknowledged as well. The philosophical aspects of those contributions have been received more critically, however. In the present essay, Dedekind's philosophical reception is reconsidered. At the essay’s core lies a comparison of Frege's and Dedekind's legacies, within and outside of (...) analytic philosophy. While the comparison proceeds historically, it is shaped by current philosophical concerns, especially by debates about neo-logicist and neo-structuralist views. In fact, philosophical and historical considerations are intertwined thoroughly, to the benefit of both. The underlying motivation is to rehabilitate Dedekind as a major philosopher of mathematics, in relation, but not necessarily in opposition, to Frege. (shrink)

The question of whether physicians or other healthcare workers are ethically entitled to strike is troubling in that it entails a conflict in obligations. This question of a conflict of obligations (and the answer to it) has wider implications for many other workers.

Reference and indexicality are two central topics in the Philosophy of Language that are closely tied together. In the first part of this book, a description theory of reference is developed and contrasted with the prevailing direct reference view with the goal of laying out their advantages and disadvantages. The author defends his version of indirect reference against well-known objections raised by Kripke in Naming and Necessity and his successors, and also addresses linguistic aspects like compositionality. In the second part, (...) a detailed survey on indexical expressions is given based on a variety of typological data. Topics addressed are, among others: Kaplan's logic of demonstratives, conversational versus utterance context, context-shifting indexicals, the deictic center, token-reflexivity, vagueness of spatial and temporal indexicals, reference rules, and the epistemic and cognitive role of indexicals. From a descriptivist perspective on reference, various examples of simple and complex indexicals are analyzed in first-order predicate logic with reified contexts. A critical discussion of essential indexicality, de se readings of attitudes and accompanying puzzles rounds up the investigation. (shrink)

In many accounts of the history of logic, especially from the second half of the twentieth century and partly still today, Frege’s first book, Begriffsschrift (1879), is singled out as the beginnin...

Ordinal, interval, and ratio scales are discussed and arguments for the thesis that “better than” comparisons reside on interval or ratio scales are laid out. It is argued that linguistic arguments are not conclusive since alternative rank-based definitions can be given, and that in general “better than” comparisons do not have a common scale type. Some comparison dimensions reside on ratio scales, whereas others do not show any evidence of lying on a scale stronger than an ordinal scale.

A layered approach to the evaluation of action alternatives with continuous time for decision making under the moral doctrine of Negative Utilitarianism is presented and briefly discussed from a philosophical perspective.

Nonindexical Context-Dependence and the Interpretation as Abduction Approach Inclusive nonindexical context-dependence occurs when the preferred interpretation of an utterance implies its lexically-derived meaning. It is argued that the corresponding processes of free or lexically mandated enrichment can be modeled as abductive inference. A form of abduction is implemented in Simple Type Theory on the basis of a notion of plausibility, which is in turn regarded a preference relation over possible worlds. Since a preordering of doxastic alternatives taken for itself only (...) amounts to a relatively vacuous ad hoc model, it needs to be combined with a rational way of learning from new evidence. Lexicographic upgrade is implemented as an example of how an agent might revise his plausibility ordering in light of new evidence. Various examples are given how this apparatus may be used to model the contextual resolution of context-dependent or semantically incomplete utterances. The described form of abduction is limited and merely serves as a proof of concept, but the idea in general has good potential as one among many ways to build a bridge between semantics and pragmatics since inclusive context-dependence is ubiquitous.

A light form of value realism is defended according to which objective properties of comparison objects make value comparisons true or false. If one object has such a better-making property and another lacks it, this is sufficient for the truth of a corresponding value comparison. However, better-making properties are only necessary and usually not sufficient parts of the justifications of value comparisons. The account is not reductionist; it remains consistent with error-theoretic positions and the view that there are normative facts.

Typical puzzles for de se attitudes by Perry and Lewis are laid out and contrasted with the original version of Jackson's Knowledge Argument. It is argued, from an epistemic perspective, that de se attitudes can be explained by looking at the way internal/introspective knowledge is formed without resorting to acquaintance or making assumptions about the Mind/Body problem.

ABSTRACT. Thought experiments about de se attitudes and Jackson’s original Knowledge Argument are compared with each other and discussed from the perspective of a computational theory of mind. It is argued that internal knowledge, i.e. knowledge formed on the basis of signals that encode aspects of their own processing rather than being intentionally directed towards external objects, suffices for explaining the seminal puzzles without resorting to acquaintance or phenomenal character as primitive notions. Since computationalism is ontologically neutral, the account also (...) explains why neither Lewis’s two gods nor Mary’s surprise in the Knowledge Argument violate physicalism. (shrink)

The Frankfurt School had a highly ambivalent relation to Judaism. On one hand, they were part of that Enlightenment tradition that opposed authority, tradition, and all institutions of the past -- including religion. They were also, for the most part, secular Jews who did not support any organized religion, or practice religious or cultural Judaism. In this sense, they were in the tradition of Heine, Marx, and Freud for whom Judaism was neither a constitutive feature of their life or work, (...) nor a significant aspect of their self-image and identity.

In an analysis of Fichte’s theoretical reflections read in the light of decisive biographical events, the present paper examines the following question: to what extent are we to assent to Fichte’s own assertion that his system is from the very outset a system of freedom? Kant’s philosophy provided the catalyst for the young Fichte because it promised a way out of the impasse of determinism. I will argue that the ultimate goal of Fichte’s lifelong struggle was to furnish a foundation (...) for genuine freedom. In reaction to both Jacobi and Schelling, Fichte’s philosophical and political investigations pursue at once the problem of grounding the “Absolute” and the relationship between individual freedom and reason as a whole.—These tensions are especially visible in Fichte’s path from the Addresses To the German Nation to the virtually unknown “Philosophical Diaries” of the final days of his life.

Principles are investigated that allow one to establish a preference ordering between possible actions based on the question of whether the acting agent himself or other agents will benefit or be harmed by the consequences of an action. It is shown that a combination of utility maximization, an altruist principle, and weak negative utilitarianism yields an ordering that seems to be intuitively appealing, although it does not necessarily reflect common everyday evaluations of actions.

This paper introduces a series of papers dealing with the topic of euthanasia as an introduction to a variety of attitudes by health-care professionals and philosophers interested in this issue. The lead in paper—and really the lead in idea—stresses the fact that what we are discussing concerns only a minority of people lucky enough to live in conditions of acceptable sanitation and who have access to medical care. The topic of euthanasia and PAS really has three questions: (1) is killing (...) another ever ethically acceptable; (2) is the participation of health professionals ethically different and (3) is it wiser to permit and set criteria (being fully aware of some dangers that lurk in such a move) or to forbid (knowing that it will occur clandestinely and uncontrolled). This paper takes no definite stand although it is very troubled by useless suffering (not only pain) by many who would wish their life and with it their suffering ended. (shrink)

The paper by Dr. Myles Sheehan “Why Doctors Hate Medical Ethics” highlights some of the problems of teaching ethics to an extremely weary group of house officers who may look at ethics as a waste of time, as a requirement that must be overcome, or as “a lot of crap” Although Dr. Shee-han's paper offers a number of interesting and valuable insights, it really fails to say why residents hate the teaching of medical ethics any more than they may hate (...) any other conference which, inevitably, intrudes on their time. In this response, I do not so much want to take issue with Sheehan's paper as to comment and to offer some of my own experiences teaching ethics. To do so, I am fully aware, may be regarded as matching anecdote with anecdote, a tiresome and ultimately futile process. (shrink)
