Experimental Explication

Two recently popular metaphilosophical movements, formal philosophy and experimental philosophy, promote what seem to be conflicting methodologies. Nonetheless, I argue that the two can be mutually supportive. I propose an experimentally‐informed variation on explication, a powerful formal philosophical tool introduced by Carnap. The resulting method, which I call “experimental explication,” provides the formalist with a means of responding to explication's gravest criticism. Moreover, this method introduces a philosophically salient, positive role for survey‐style experiments while steering clear of several objections that critics of “positive experimental philosophy” raise. Thus, it provides the experimentalist with a more defensible example of how empirical work can have positive philosophical import. For these reasons, experimental explication should appeal to experimental philosophers (at least those working within the positive program) and formal philosophers alike.     

On the Quinean-analyticity of mathematical propositions

This paper investigates the relation between Carnap and Quine??s views on analyticity on the one hand, and their views on philosophical analysis or explication on the other. I argue that the stance each takes on what constitutes a successful explication largely dictates the view they take on analyticity. I show that although acknowledged by neither party (in fact Quine frequently expressed his agreement with Carnap on this subject) their views on explication are substantially different. I argue that this difference not only explains their differences on the question of analyticity, but points to a Quinean way to answer a challenge that Quine posed to Carnap. The answer to this challenge leads to a Quinean view of analyticity such that arithmetical truths are analytic, according to Quine??s own remarks, and set theory is at least defensibly analytic.     

Explicationist Epistemology and the Explanatory Role of Knowledge

Journal for General Philosophy of Science - It has been argued that much of contemporary epistemology can be unified under Carnap’s methodology of explication, which originated in the...     

Explication of Inductive Probability

Inductive probability is the logical concept of probability in ordinary language. It is vague but it can be explicated by defining a clear and precise concept that can serve some of the same purposes. This paper presents a general method for doing such an explication and then a particular explication due to Carnap. Common criticisms of Carnap’s inductive logic are examined; it is shown that most of them are spurious and the others are not fundamental.     

The Epistemic Integrity of Scientific Research

We live in a world in which scientific expertise and its epistemic authority become more important. On the other hand, the financial interests in research, which could potentially corrupt science, are increasing. Due to these two tendencies, a concern for the integrity of scientific research becomes increasingly vital. This concern is, however, hollow if we do not have a clear account of research integrity. Therefore, it is important that we explicate this concept. Following Rudolf Carnap’s characterization of the task of explication, this means that we should develop a concept that is (1) similar to our common sense notion of research integrity, (2) exact, (3) fruitful, and (4) as simple as possible. Since existing concepts do not meet these four requirements, we develop a new concept in this article. We describe a concept of epistemic integrity that is based on the property of deceptiveness, and argue that this concept does meet Carnap’s four requirements of explication. To illustrate and support our claims we use several examples from scientific practice, mainly from biomedical research.     

形式显示的现象学--海德格尔早期弗莱堡讲座研究

本文讨论海德格尔早期弗莱堡讲座中的现象学。作者从题域和方法两个角度上探讨海德格尔这个时期的形式显示现象学。就题域来说,海德格尔试图突破胡塞尔现象学的“知识”或“理论”局限,深入到“前理论的”层面,即所谓前理论的“原始东西”;就方法来说,海德格尔沉思和实践了他所谓的“形式显示”的思路和言路,以此力求与传统哲学的形式化思想方法划界。作者认为,“形式显示”的现象学方法乃是海德格尔在《存在与时间》之前的现象学哲思的最富特色和创意的成分;而由于这种方法上的探索也影响到后期海德格尔的思想道路,因此一般而言,它也标志着海德格尔全部思想的现象学特质。     

Vagueness,Kant and Topology: a Study of Formal Epistemology

In this paper we propose an approach to vagueness characterised by two features. The first one is philosophical: we move along a Kantian path emphasizing the knowing subject’s conceptual apparatus. The second one is formal: to face vagueness, and our philosophical view on it, we propose to use topology and formal topology. We show that the Kantian and the topological features joined together allow us an atypical, but promising, way of considering vagueness.     

On the Logical Positivists' Theory of Truth: The Fundamental Problem and a New Perspective

The present article purports to show that the protocol sentence debate, pursued by some leading members of the Vienna Circle in the mid-1930s, was essentially a controversy over the explanation and the real significance of the concept of truth. It is further shown that the fundamental issue underlying the discussions about the concept of truth was the relationship between form and content, as well as between logic/language and the world. R. Carnap was the philosopher who most explicitly and systematically attempted to come to grips with this problem. It is shown that the form-content distinction pervades the three most important phases of Carnap's philosophical development: the structuralist (in Der logische Aufbau der Welt), the syntactical and the semantical. His final semantical stance is essentially determined by the concept of linguistic frameworks. The article purports to demonstrate that this concept cannot be dispensed with in philosophy, but that Carnap failed to work out its ontological implications. Finally, the concept of an internal ontology is briefly delineated. This revised version was published online in August 2006 with corrections to the Cover Date.     

Revising Carnap’s Semantic Conception of Modality

I provide a tableau system and completeness proof for a revised version of Carnap??s semantics for quantified modal logic. For Carnap, a sentence is possible if it is true in some first order model. However, in a similar fashion to second order logic, no sound and complete proof theory can be provided for this semantics. This factor contributed to the ultimate disappearance of Carnapian modal logic from contemporary philosophical discussion. The proof theory I discuss comes close to Carnap??s semantic vision and provides an interesting counterpoint to mainstream approaches to modal logic. Despite its historical origins, my intention is to demonstrate that this approach to modal logic is worthy of contemporary attention and that current debate is the poorer for its absence.     

The road to Experience and Prediction from within: Hans Reichenbach��s scientific correspondence from Berlin to Istanbul

Ever since the first meeting of the proponents of the emerging Logical Empiricism in 1923, there existed philosophical differences as well as personal rivalries between the groups in Berlin and Vienna, headed by Hans Reichenbach and Moritz Schlick, respectively. Early theoretical tensions between Schlick and Reichenbach were caused by Reichenbach??s (neo)Kantian roots (esp. his version of the relativized a priori), who himself regarded the Vienna Circle as a sort of anti-realist ??positivist school????as he described it in his Experience and Prediction (1938). One result of this divergence was Schlick??s preference of Carnap over Reichenbach for a position at the University of Vienna (in 1926), and his decision not to serve as a co-editor with Reichenbach for the journal Erkenntnis that they jointly established in 1930 (which was then co-edited by Carnap and Reichenbach from 1930 to 1938). A second split rooted in different views on induction and probability, which culminated in the Hans Reichenbach??s refusal to serve as an invited author on probability within the International Encyclopedia of Unified Science series ed. by Rudolf Carnap, Charles Morris and Otto Neurath from 1938 onwards. In this regard it is remarkable that also Richard von Mises, who was the second leading figure of Logical Empiricism in Turkish exile, criticized the theory of probability put forward by his former Berlin colleague. In this paper I analyse this controversial exchange, drawing on the relevant correspondence and asking whether these (meta)philosophical differences were a typical feature of the pluralism inherent in Logical Empiricism in general.     

Idealistische Häresien in der Wissenschaftsphilosophie: Cassirer, Carnap und Kuhn

Idealist Heresies in Philosophy of Science: Cassirer, Carnap, and Kuhn. As common wisdom has it, philosophy of science in the analytic tradition and idealist philosophy are incompatible. Usually, not much effort is spent for explaining what is to be understood by idealism. Rather, it is taken for granted that idealism is an obsolete and unscientific philosophical account. In this paper it is argued that this thesis needs some qualification. Taking Carnap and Kuhn as paradigmatic examples of positivist and postpositivist philosophies of science it is shown that these accounts share important features with Cassirer's idealist philosophy of science developed in the first half of this century. As it turns out, often Cassirer is more modern than those classical philosophers of (post)posivitist philosophy of science. For instance, Quine's criticism against Carnap's empiricist philosophy of science launched in Two Dogmas of Empiricism is anticipated by Cassirer for several decades. This revised version was published online in August 2006 with corrections to the Cover Date.     

On the Structure of Twentieth-Century Philosophy

Abstract: It makes sense to ask from time to time where we are in the philosophical discussion. This article reviews the debate in the twentieth century. Michael Friedman has recently argued that the split between Continental and analytic philosophy is due to the inability, because of war, to carry forward a genuine debate begun by Heidegger and Carnap around the time of Heidegger's public controversy with Cassirer at Davos in 1929. I, however, argue that there was not even the beginning of a genuine debate between Heidegger and Carnap. I argue further that the split between analytic and Continental philosophy originated earlier, in the analytic attack on idealism at the beginning of the century. And finally I argue that the differences among analytic philosophy, Continental philosophy, and pragmatism, the third main current of twentieth‐century philosophy, can be traced to differing reactions to Kant.     

Metaphysics and the philosophical imagination

Methods and goals in philosophy are discussed by first describing an ideal, and then looking at how the ideal might be approached. David Lewis??s work in metaphysics is critically examined and compared to analogous work by Mackie and Carnap. Some large-scale philosophical systematic work, especially in metaphysics, is best treated as model-building, in a sense of that term that draws on the philosophy of science. Models are constructed in a way that involves deliberate simplification, or other imaginative modification of reality, in order to make relationships visible or problems tractable.     

Carnap and Kuhn: On the Relation between the Logic of Science and the History of Science

This paper offers a refutation of J. C. Pinto de Oliveira’s recent critique of revisionist Carnap scholarship as giving undue weight to two brief letters to Kuhn expressing his interest in the latter’s work. First an argument is provided to show that Carnap and Kuhn are by no means divided by a radical mismatch of their conceptions of the rationality of science as supposedly evidenced by their stance towards the distinction of the contexts of discovery and justification. This is followed by an argument to the effect that the fact that Carnap’s own work concentrated on formal aspects of scientific theories does not licence the conclusion that he thought historical investigations and concerns irrelevant for what we nowadays would rightly call “philosophy of science”.     

Does Ontology Rest on a Mistake?: Andre Gallois

I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions. In the first section I set out what I take that distinction, as Carnap draws it, to be, and spell out a central motivation Carnap has for invoking it. In the second section I endorse, and augment, Yablo's response to Quine's arguments against Carnap. In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second.     

A philosophical reflection on the epistemology and methodology of indigenous psychologies

In order to answer the three crucial questions (why, what and how) about the development of indigenous psychology, three levels of breakthrough need to be made, namely, philosophical reflection, theoretical construction and empirical research. The controversial issues that have occurred in the earlier development of indigenous psychology are analyzed in terms of the switch in Western philosophy of science from positivism to post-positivism. Based on this analysis, it is argued that indigenous psychologists should construct formal theories illustrating the functioning of the human mind that may be applicable to various cultures, and then use these theories to study the particular mentalities of people in a given culture with the scientific methods of empirical research.     

Russell's Influence On Carnap's Aufbau

This paper concerns the debate on the nature of Rudolf Carnap'sproject in his 1928 book The Logical Structure of the Worldor Aufbau. Michael Friedman and Alan Richardson haveinitiated much of this debate. They claim that the Aufbauis best understood as a work that is firmly grounded inneo-Kantian philosophy. They have made these claims in oppositionto Quine and Goodman's ``received view' of the Aufbau. Thereceived view sees the Aufbau as an attempt to carry out indetail Russell's external world program. I argue that both sidesof this debate have made errors in their interpretation ofRussell. These errors have led these interpreters to misunderstandthe connection between Russell's project and Carnap's project.Russell in fact exerted a crucial influence on Carnap in the1920s. This influence is complicated, however, due to the factthat Russell and Carnap disagreed on many philosophical issues. Iconclude that interpretations of the Aufbau that ignoreRussell's influence are incomplete.     

Philosophical Intuition Is the Capacity to Recognize one’s Epistemic Position. An Old-Fashion Approach Based on Russell,Carnap, Wittgenstein,and Husserl

Philosophical intuition has become one of the most debated problems in recent years, largely due to the rise of the movement called experimental philosophy which challenged the conviction that philosophers have some special insight into abstract ideas such as being, knowledge, good and evil, intentional action, etc. In response to the challenge, some authors claim that there is a special cognitive faculty called philosophical intuition which delivers justification to philosophical theses, while some others deny it based on experimental results. A relatively smaller group of researchers aim at clarifying what the alleged intuition is. I follow the latter path. In this paper I argue that philosophical intuition is in the first place the capacity enabling one to what I refer to as the recognition of one’s epistemic position. The latter means becoming aware of the seemingly trivial “fact” that the way in which the world manifests itself depends on the cognitive apparatus one has, thereby propelling one to draw a distinction between appearances and reality. The recognition at stake is a very specific capacity to approach the world solely as it is experienced. This capacity, I argue, is the core and the defining feature of philosophical intuition. As part of my argumentation I also distinguish between the intuition in question and its different manifestations; and then introduce a novel notion of erotetic intuition. My argument is called “old-fashion” to emphasize the fact that I draw mostly on four figures who were pivotal in the twentieth- century philosophy and whose influence on the current debate concerning philosophical intuition should be, I believe, stronger than it is; I mean Russell, Carnap, Wittgenstein, and Husserl.

     

The adequacy of language 1

he notion of linguistic adequacy (the adequacy of sentences to express or describe) is explicated in terms of a set theoretical model of the communication situation. Roughly: a message is adequate to the degree it answers the receiver's questions. Adequacy is distinguished from openness, in such a way that a message can be both completely adequate in a communication event and also “inexhaustibly open”;. Using this explication it is possible to translate and clarify several familiar philosophical theses concerning the adequacy of language. The view that “humanistic”; language differs from scientific language is clarified and criticized. Seven types of empirical test of the explication are discussed.
