Hans Reichenbach was a formidable figure in early-twentieth-century philosophy of science. Educated in Germany, he was influential in establishing the so-called Berlin Circle, a companion group to the Vienna Circle founded by his colleague Rudolph Carnap. The movement they founded—usually known as "logical positivism," although it is more precisely known as "scientific philosophy" or "logical empiricism"—was a form of epistemology that privileged scientific over metaphysical truths. Reichenbach, like other young philosophers of the exact sciences of his generation, was (...) deeply impressed by the far-reaching changes in physics brought about by Einstein's special and general theories of relativity. Reichenbach responded to scientific advances by doing fundamental work in space-time theories, in quantum mechanics, in statistical mechanics, and in the development of probability theory—making him the most important philosopher of physics in the first generation of logical empiricism. Forced from his academic position by the Nazi race laws in 1933, Reichenbach wrote _Experience and Prediction_ at the University of Istanbul, where had had fled, expressly to introduce logical positivism to English speakers. In the two decades following World War II, during the explosion of scientific advances in North America, logical positivism was the reigning theory of the philosophy of science and Reichenbach was at the peak of his career. But, inevitably, support for logical positivism began to wane as it became obvious that the justification of scientific theories could not be entirely resolved by relying on strictly formal, technical processes. The growth of the discipline of the history of philosophy of science, which has created an audience of scholars eager for seminal classics in scientific philosophy, and the evidence supporting a historicist paradigm within logical positivism are two important reasons to make _Experience and Prediction_ available once again. "Hans Reichenbach's_ Experience and Prediction_ is one of the most important books in twentieth-century philosophy of science. Its author was, along with Rudolf Carnap, one of the two principal ambassadors to North America of the exciting new European philosophical movement known here under the names 'Logical Positivism' and 'Scientific Philosophy.' In 1938, when the book was published, Reichenbach was an exile from his native Germany, teaching in Istanbul, Turkey, and about to emigrate to the United States to take up a prestigious position at UCLA. He wrote_ Experience and Prediction_ in English as his calling card to his new American colleagues. More than any other single book,_ Experience and Prediction_ set the agenda for the new discipline of the philosophy of science that was to emerge after World War II as, perhaps, the most exciting new area in North American philosophy. Many of the problems still at the focus of discussion were given their classic formulations in this book. Long out of print,_ Experience and Prediction_ appears here in a new edition accompanied by a splendid historical introduction by the noted young philosopher and historian of the philosophy of science, Alan Richardson. A jewel of a book may once again be appreciated in its proper setting." —Don A. Howard, University of Notre Dame. (shrink)

Philosophers often write in a particular mood; their work is playful, strident, strenuous, or nostalgic. On the face of it, these moods contribute little to a philosophical argument and are merely incidental. However, I will argue that the cognitive science of moods and emotions offers us reasons to suspect that mood is relevant for philosophical texts. I use examples from Friedrich Nietzsche and Rudolph Carnap to illustrate the role moods play in their arguments. As readers and writers of (...) philosophical texts, we do well to attend to mood.

The verification theory of meaning aims to characterise what it is for a sentence to be meaningful and also what kind of abstract object the meaning of a sentence is. A brief outline is given by Rudolph Carnap, one of the theory's most prominent defenders: If we knew what it would be for a given sentence to be found true then we would know what its meaning is. [...] thus the meaning of a sentence is in a certain (...) sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. [4: 420] In short, the verification theory of meaning claims that the meaning of a sentence is the method of its verification. (shrink)

Karl Popper, ca raționalist critic, a fost un oponent al tuturor formelor de scepticism, convenționalism și relativism în știință. În 1935 a scris Logica cercetării (Logik der Forschung. Zur Erkenntnistheorie der modernen Naturwissenschaft), traducând ulterior cartea în engleză și publicând-o sub titlul The Logic of Scientific Discovery (1959) considerată ca o lucrare de pionierat în domeniu. Multe dintre argumentele din această carte sunt îndreptate împotriva membrilor "Cercului Vienez", precum Moritz Schlick, Otto Neurath, Rudolph Carnap, Hans Reichenbach, Carl Hempel (...) și Herbert Feigl. Popper este de acord cu aceștia cu privire la aspectele generale ale metodologiei științifice și neîncrederea lor în metodologia filosofică tradițională, dar soluțiile sale au fost semnificativ diferite. Popper a contribuit semnificativ la dezbaterile privind metodologia științifică generală, demarcarea științei de pseudoștiință, natura probabilității și metodologia științelor sociale. (shrink)

Zur Erkenntnistheorie der modernen Naturwissenschaft, traduisant plus tard le livre en anglais et le publiant sous le titre The Logic of Scientific Discovery (1959), considéré comme un travail de pionnier dans son domaine. De nombreux arguments de ce livre sont dirigés contre les membres du « Cercle de Vienne », (...) tels que Moritz Schlick, Otto Neurath, Rudolph Carnap, Hans Reichenbach, Carl Hempel et Herbert Feigl. Popper est d'accord avec eux sur les aspects généraux de la méthodologie scientifique et sur leur méfiance à l'égard de la méthodologie philosophique traditionnelle, mais ses solutions ont été sensiblement différentes. Popper a largement contribué aux débats sur la méthodologie scientifique générale, la démarcation de la pseudo-science, la nature des probabilités et la méthodologie des sciences sociales.

Assertions about appearances license inferences about the speaker's perceptual experience. For instance, if I assert, 'Tom looks like he's cooking', you will infer both that I am visually acquainted with Tom (what I call the "individual acquaintance inference"), and that I am visually acquainted with evidence that Tom is cooking (what I call the "evidential acquaintance inference"). By contrast, if I assert, 'It looks like Tom is cooking', only the latter inference is licensed. I develop an account of the acquaintance (...) inferences of appearance assertions building on two main previous lines of research: first, the copy raising literature, which has aimed to account for individual acquaintance inferences through the "perceptual source" semantic role; second, the subjectivity literature, which has focused on the status of acquaintance inferences with predicates of personal taste, but hasn't given much attention to the added complexities introduced by appearance language. I begin by developing what I take to be the most empirically-sound version of a perceptual source analysis. I then show how its insights can be maintained, while however taking anything about perception out of the truth conditions of appearance sentences. This, together with the assumption that appearance assertions express experiential attitudes, allows us to capture the acquaintance inferences of bare appearance assertions without making incorrect predictions about the behavior of appearance verbs in embedded environments.

Faultless disagreement and faultless retraction have been taken to motivate relativism for predicates of personal taste, like ‘tasty’. Less attention has been devoted to the question of what aspect of their meaning underlies this relativist behavior. This paper illustrates these same phenomena with a new category of expressions: appearance predicates, like ‘tastes vegan’ and ‘looks blue’. Appearance predicates and predicates of personal taste both fall into the broader category of experiential predicates. Approaching predicates of personal taste from this angle suggests (...) that their relativist behavior is due to their experience-sensitivity, rather than their evaluative meaning. Furthermore, appearance predicates hold interest beyond what they can teach us about predicates of personal taste. Examination of a variety of uses of appearance predicates reveals that they give rise to relativist behavior for a variety of reasons—including some that apply also to other types of expressions, such as epistemic modals and comparative terms. This paper thus serves both to probe the source of relativist behavior in discourse about personal taste, as well as to map out this kind of behavior in the rich and under-explored discourse about appearances.

We offer a novel account of metalinguistic comparatives, such as 'Al is more wise than clever'. On our view, metalinguistic comparatives express comparative commitments to conventions. Thus, 'Al is more wise than clever' expresses that the speaker has a stronger commitment to a convention on which Al is wise than to a convention on which she is clever. This view avoids problems facing previous approaches to metalinguistic comparatives. It also fits within a broader framework—independently motivated by metalinguistic negotiations and convention-shiftingexpressions— (...) that gives linguistic conventions a role in the semantics. (shrink)

In theoretical work about the language of personal taste, the canonical example is the simple predicate of personal taste, 'tasty'. We can also express the same positive gustatory evaluation with the complex expression, 'taste good'. But there is a challenge for an analysis of 'taste good': While it can be used equivalently with 'tasty', it need not be (for instance, imagine it used by someone who can identify good wines by taste but doesn't enjoy them). This kind of two-faced behavior (...) systematically arises with complex sensory-evaluative predicates, including those with other appearance verbs, such as 'look splendid' and 'sound nice'. I examine two strategies for capturing these different uses: one that posits an ambiguity in appearance verbs, and one that does not. The former is in line with an approach to 'look'-statements prominent in work in philosophy of perception, and I consider how the motivation given in that tradition carries over to the present context. I then show how the data used to support the verbal ambiguity approach can equally be captured on the second strategy, which appeals only to independently-motivated flexibility in adjective meaning. I close by discussing some considerations that are relevant for choosing between the two options. (shrink)

Simple claims with the verb ‘seem’, as well as the specific sensory verbs, ‘look’, ‘sound’, etc., require the speaker to have some relevant kind of perceptual acquaintance (Pearson, 2013; Ninan, 2014). But different forms of these reports differ in their perceptual requirements. For example, the copy raising (CR) report, ‘Tom seems like he’s cooking’ requires the speaker to have seen Tom, while its expletive subject (ES) variant, ‘It seems like Tom is cooking’, does not (Rogers, 1972; Asudeh and Toivonen, 2012). (...) This contrast has led some theorists to hold that the matrix subject in CR constructions is uniformly interpreted as the perceptual source (p-source) (Asudeh and Toivonen, 2012; Rett and Hyams, 2014). Others, based on examples of CR reports that seem not to require perception of the referent of the matrix subject, have taken the p-source interpretation instead to be non-uniform across CR reports (Landau, 2011; Doran, 2015). We reconsider these theoretical approaches to copy raising in light of new experimental work probing the sensitivity of these requirements to the matrix verb, the embedded ‘like’-clause, and the context. While we find some motivation for a non-uniform p-source analysis, it comes from importantly different cases than those others have relied on. Furthermore, our findings cast doubt on the prevalent assumption that the perceptual requirements of CR reports are to be captured solely by the presence or absence of the p-source interpretation. We suggest that the data motivating a non-uniform p-source view are better captured by an alternative approach, which makes use of a more minimal evidential source role, in place of the perceptual source role. We close by considering the relationship between English copy raising and evidential constructions cross-linguistically. (shrink)

This paper describes the contemporary phenomenological understanding of subjectivity as non dual awareness.

This paper focuses on the phenomenology of healing within the awareness field.

Some assertions give rise to the acquaintance inference: the inference that the speaker is acquainted with some individual. Discussion of the acquaintance inference has previously focused on assertions about aesthetic matters and personal tastes (e.g. 'The cake is tasty'), but it also arises with reports about how things seem (e.g. 'Tom seems like he's cooking'). 'Seem'-reports give rise to puzzling acquaintance behavior, with no analogue in the previously-discussed domains. In particular, these reports call for a distinction between the specific acquaintance (...) inference (that the speaker is acquainted with a specific individual) and the general acquaintance inference (that the speaker is acquainted with something or other of relevance). We frame a novel empirical generalization -- the specific with stage-level generalization -- that systematizes the observed behavior, in terms of the semantics of the embedded 'like'-clause. We present supporting experimental work, and explain why the generalization makes sense given the evidential role of 'seem'-reports. Finally, we discuss the relevance of this result for extant proposals about the semantics of 'seem'-reports. More modestly, it fills a gap in previous theories by identifying which reports get which of two possible interpretations; more radically, it suggests a revision of the kind of explanation that should be given for the acquaintance behavior in question.

This paper focuses on the base of awareness as space and light.

In ordinary conversation, speakers disagree not only about worldly facts, but also about how to use language to describe the world. For example, disagreement about whether Buffalo is in the American Midwest, whether Pluto is a planet, or whether someone has been canceled, can persist even with agreement about all the relevant facts. The speakers may still engage in “metalinguistic negotiation”—disputing what to mean by “Midwest”, “planet”, or “cancel”. I first motivate an approach to metalinguistic negotiation that generalizes a Stalnakerian (...) theory of communication by including linguistic commitments in the conversational common ground. Then, I turn to cases where the very status of a disagreement as metalinguistic or factual is unclear or contested. For example, after the publication of the New York Times Magazine’s 1619 Project, some responses claimed to identify factual errors, while others took those same “errors” to be matters of interpretation. I’ll consider how to extend our theorizing about metalinguistic negotiation to this type of (even more) “meta” disagreement, using the discussion following the 1619 Project as a case study. On my view, in most such cases, there will be a metalinguistic negotiation going on. Still, I explain several ways in which, despite a dispute being metalinguistic, the factualist side can sometimes receive important vindication. I also discuss why it can make sense for speakers to contest the status of a dispute. (shrink)

Theophrastus' treatise "Metaphysics" contains a compact and critical reconstruction of unsolved systematic problems of classical Greek philosophy. It is primarily about fundamental problems of ontology and natural philosophy, such as the question of the interdependence of principles and perceptible phenomena or the plausibility of teleology as a methodical principle of the explanation of nature. The aim of the critical Greek-German edition (with introduction and commentary) is to make visible the systematic significance of Theophrastus' critique of metaphysics.
