Ramsification and Inductive Inference
Forthcoming in: SYNTHESE Ramsification and Inductive Inference Panu Raatikainen Abstract. An argument, different from the Newman objection, against the view that the cognitive content of a theory is exhausted by its Ramsey sentence is reviewed. The crux of the argument is that Ramsification may ruin inductive systematization between theory and observation. The argument also has some implications concerning the issue of underdetermination. 1. Introduction Scientific realism proposes that we are justified in believing that successful theories of mature science are at least approximately true, and that the unobservable theoretical entities they postulate really exist. The standard argument in favour of this view is the so•called “no• miracles argument”: the practical and observational success of science would be miraculous if scientific theories were not at least approximately true descriptions of the world, and the theoretical objects they postulate did not exist. Then again, arguments exist which seem to undermine scientific realism, and the no•miracles argument. Most importantly, perhaps, there are arguments which lean on the actual history of science and radical theory changes therein – for example, the notorious “pessimistic meta•induction”, and also various less general arguments to the same effect. Roughly, the thesis is that many past theories in science have turned out to be to a large extent false, and their theoretical terms non•referring; therefore – it is concluded – it is not justified to expect that the theoretical entities postulated by present theories exist either (see Laudan 1981). The view known asStructural Realism has emerged over the past two decades and seems to enjoy some popularity among philosophers of science. -
Quasi-Truth As Truth of a Ramsey Sentence
Quasi-Truth as Truth of a Ramsey Sentence Sebastian Lutz∗ Draft: 2011–08–07 Abstract I show the quasi-truth of a sentence in a partial structure to be equivalent to the truth of a specific Ramsey sentence in a structure that corresponds naturally to the partial structure. Hence quasi-truth, the core notion of the partial structures approach, can be captured in the terms of the received view on scientific theories as developed by Carnap and Hempel. I further show that a mapping is a partial homomorphism/isomorphism between two partial structures if and only if it is a homomorphism/isomorphism between their corresponding structures. It is a corollary that the partial structures approach can be expressed in first or second order model theory. Keywords: partial structure; quasi-truth; pragmatic truth; partial truth; subtruth; partial homomorphism; partial isomorphism; model theory; expansion; Ramsey sentence; received view; logical empiricism The partial structures approach is in the vanguard of the semantic view on scientific theories and models (da Costa and French 2000; Le Bihan 2011, n. 3, §5), and is one of the main reasons why the received view on scientific theories as developed by, for example, Carnap(1966) and Hempel(1958) within logical empiricism is considered inferior to the semantic view (French and Ladyman 1999). I will show that the core notion of the partial structures approach, quasi-truth, can be captured very naturally within the received view. The partial structures approach is motivated by a simple epistemological point: Most of the time, scientists do not have enough information about a domain to determine its structure with arbitrary precision. -

I3, JULY 9, 19-0 HOW TO DEFINE THEORETICAL TERMS M OST philosophers of science agree that, when a newly proposed scientific theory introduces new terms, we usually cannot define the new terms using only the old terms we understood beforehand. On the contrary, I contend that there is a general method for defining the newly introduced theo- retical terms. Most philosophers of science also agree that, in order to reduce one scientific theory to another, we need to posit bridge laws: new laws, independent of the reducing theory, which serve to identify phenomena described in terms of the reduced theory with phe nomena described in terms of the reducing theory. -
Carnap on Empirical Significance
Carnap on Empirical Significance Sebastian Lutz∗ Preprint: 2014–04–30 Abstract Carnap’s search for a criterion of empirical significance is usually con- sidered a failure. I argue that the results from two out of his three different approaches are at the very least problematic, but that one approach led to success. Carnap’s criterion of translatability into logical syntax is too vague to allow definite results. His criteria for terms—introducibility by reduction sentences and his criterion from “The Methodological Character of Theoretical Concepts”—are almost trivial and have no clear relation to the empirical significance of sentences. However, his criteria for sentences— translatability, verifiability, falsifiability, confirmability—are usable, and under assumption of the Carnap sentence, verifiability, falsifiability, and translatability become equivalent. The price for the Carnap sentence approach is that metaphysics cannot always be shown to be non-significant.

Truth and Simplicity F
Brit. J. Phil. Sci. 58 (2007), 379–386 Truth and Simplicity F. P. Ramsey 1 Preamble ‘Truth and Simplicity’ is the title we have supplied for a very remarkable nine page typescript of a talk that Ramsey gave to the Cambridge Apostles on April 29, 1922.1 It is a relatively early work but it already touches even in such brief compass on several topics of fundamental philosophical interest: truth, ontological simplicity, the theory of types, facts, universals, and probability, that are recurrent themes found in most of Ramsey’s papers, published and posthumous. The present paper has not appeared in any of the classic collections, and it comes as a pleasant surprise—just when we thought we had seen it all.2 In the paper, Ramsey develops two ideas he thinks are related: that ‘true’ is an incomplete symbol, and ‘the only things in whose existence we have reason to believe are simple, not complex’. The first relies on Russell’s notion of an incomplete symbol and the second he says is a view now (1922) held by Russell, and, as he generously says, he got it from Russell in conversation and doubts whether he would ever have thought of it by himself. Ramsey is very clear as to what simplicity requires: I mean that there are no classes, no complex properties or relations, or facts; and that the phrases which appear to stand for these things are incomplete symbols. Ramsey says later in this paper, that the statements that ‘true’ is an incomplete symbol and that everything in the world is simple are part of the same view. -

Hans Reichenbach
Coming to America: Carnap, Reichenbach and the Great Intellectual Migration Part II: Hans Reichenbach Sander Verhaegh Tilburg University Ich habe das Gefühl, dass gerade Amerika mit seinem Sinn für das konkrete und technische mehr Verständnis haben müsste für meine naturwissenschaftliche Philosophie als Europa, wo noch immer die mystisch-metaphysischen Spekulationen als die wahre Philosophie angesehen werden. ⎯ Reichenbach to Sidney Hook, January 31, 1935 II.1. Introduction In the late-1930s, Rudolf Carnap and Hans Reichenbach, arguably the two most prominent scientific philosophers of their time, emigrated to the United States, escaping the increasingly perilous situation on the continent. Once in the U.S., the two significantly changed the American philosophical landscape. In this two-part paper, I reconstruct Carnap’s and Reichenbach’s surprisingly numerous interactions with American scholars throughout the 1920s and 1930s in order to better explain the transformation of analytic philosophy in the years before and after the Second World War. In the first part of this paper, I reconstructed Carnap’s contacts with American philosophers throughout the 1920s and 1930s. In this second part, I focus on Reichenbach’s interactions with the American philosophical community before he moved to the United States. I argue that some of Reichenbach’s work from the mid-1930s⎯ in particular Experience and Prediction (1938)⎯ can be better understood if we take into account the context in which it was written. This paper is structured as follows. After an overview of Reichenbach’s ignorance about Anglophone philosophy in the first stages of his academic career (§II.2), I reconstruct his ‘American turn’ in the early 1930s, focusing especially on the reception of his philosophy by a group of New York philosophers (§II.3). -

Carnap's Logic of Science and Reference to the Present Moment
Carnap's Logic of Science and Reference to the Present Moment Florian Fischer Abstract The important switch from the so-called old B-theory to the new tenseless theory of time (NTT), which had significant implications for the field of tense and indexicals, occurred after Carnap's era. Against this new background, Carnap's original inter-translatability thesis can no longer be upheld. The most natural way out would be to modify Carnap's position according to the NTT; but this is not compatible with Carnap's metaphysi- cal neutrality thesis. Even worse, Carnap's work on measurement theory can be used to develop an argument in favour of the A-theory. I argue that there are tensed basic sentences which are needed in order to construct a tenseless system and thus cannot be translated without loss of meaning into tenseless ones (old B-theory) or made true by tenseless facts (NTT). Keywords: Rudolf Carnap, Philosophy of Time, Tense vs. Tenseless Theory, A-Theory, B-Theory, New Tenseless Theory of Time 1 Carnap and Tense This paper brings the work of Rudolf Carnap together with the modern debate about tense in the philosophy of time. It is an interesting fact that these fields have never been put together,1 despite the fact, or so I believe, that their content is deeply connected. The debate between so-called tensed and tenseless theories is a central issue in contemporary philosophy of time. `Tensers hold that grammatical tense is semantically irreducible, while detensers hold that tense is semantically reducible' [69, p. 2]. Under the buzz phrase `tensed versus tenseless theory', I subsume different philosophical positions about the reference to the present mo- ment. -

Forthcoming in Time and Identity: Topics in Contemporary Philosophy
Time and Identity: Topics in Contemporary Philosophy, Vol. 6, Michael O’Rourke, Joseph Campbell, and Harry Silverstein, eds. (Cambridge MA: MIT Press, 2009). Temporal Reality Lynne Rudder Baker University of Massachusetts Amherst Nonphilosophers, if they think of philosophy at all, wonder why people work in metaphysics. After all, metaphysics, as Auden once said of poetry, makes nothing happen.1 Yet some very intelligent people are driven to spend their lives exploring metaphysical theses. Part of what motivates metaphysicians is the appeal of grizzly puzzles (like the paradox of the heap or the puzzle of the ship of Theseus). But the main reason to work in metaphysics, for me at least, is to understand the shared world that we all encounter and interact with. And the shared world that we all encounter includes us self-conscious beings and our experience. The world that we inhabit is unavoidably a temporal world: the signing of the Declaration of Independence is later than the Lisbon earthquake; the Cold War is in the past; your death is in the future. There is no getting away from time. The ontology of time is currently dominated by two theories: Presentism, according to which “only currently existing objects are real,”2 and Eternalism, according to which “past and future objects and times are just as real as currently existing ones.”3 In my opinion, neither Presentism nor Eternalism yields a satisfactory ontology of time. Presentism seems both implausible on its face and in conflict with the Special Theory of Relativity, and Eternalism gives us no handle on time as universally experienced in terms of an ongoing now. -
This Volume on the Vienna Circle's Influence in the Nordic Countries
Vol. 8, no. 1 (2013) Category: Review essay Written by Carlo Penco This volume on the Vienna Circle’s influence in the Nordic countries gives a very interesting presentation of an almost forgotten landmark. In the years preceding the Second World War, European philosophy was at the high point of its intellectual vitality. Everywhere philosophical societies promoted a dense network of connections among scholars, with international meetings and strong links among individuals and associations. In this context, the Vienna Circle emerges as one of the many, also if probably the most well-known, centres of diffusion of a new style of philosophy, closely linked to the new logic and with a strongly empiricist attitude. At the same time, empiricism, formal logic and psychology constituted (and still constitute) the common background of most of the Nordic philosophers, a background which permitted them to develop connections with Vienna’s cultural environment (well known also for the work of psychologists such as Sigmund Freud, but also Charlotte and Karl Bühler). This piece of history, although limited to the connection between Nordic philosophy and Vienna Circle, helps to clarify the history of European philosophy, and the sharp difference of Nordic philosophy in respect of the development of philosophy in Southern and Central Europe in the half a century following the Second World War. The editors say in the introduction: . one of the least known networks of the Vienna Circle is the “Nordic connection”. This connection had a continuing influence for many of the coming decades, beginning with the earliest phase of the Vienna Circle and continuing with a number of adaptations and innovations well into contemporary times.
