Rudolf Carnap delivered the hitherto unpublished lecture ‘Theoretical Concepts in Science’ at the meeting of the American Philosophical Association, Pacific Division, at Santa Barbara, California, on 29 December 1959. It was part of a symposium on ‘Carnap’s views on Theoretical Concepts in Science’. In the bibliography that appears in the end of the volume, ‘The Philosophy of Rudolf Carnap’, edited by Paul Arthur Schilpp, a revised version of this address appears to be among Carnap’s forthcoming papers. But although Carnap started (...) to revise it, he never finished the revision,1 and never published the unrevised transcript. Perhaps this is because variants of the approach to theoretical concepts presented for the first time in the Santa Barbara lecture have appeared in other papers of his (cf. the editorial footnotes in Carnap’s lecture). Still, I think, the Santa Barbara address is a little philosophical gem that needs to see the light of day. The document that follows is the unrevised transcript of Carnap’s lecture.2 Its style, then, is that of an oral presentation. I decided to leave it as it is, making only very minor stylistic changes—which, except those related to punctuation, are indicated by curly brackets.3 I think that reading this lecture is a rewarding experience, punctuated as the lecture is with odd remarks and autobiographical points. One can almost envisage.. (shrink)

Over the last twenty years, Bas van Fraassen has developed a “new epistemology”: an attempt to sail between Bayesianism and traditional epistemology. He calls his own alternative “voluntarism”. A constant pillar of his thought is the thought that rationality involves permission rather than obligation. The present paper aims to offer an appraisal of van Fraassen’s conception of rationality. In section 2, I review the Bayesian structural conception of rationality and argue that it has been found wanting. In sections 3 and (...) 4, I analyse van Fraassen’s voluntarism. I raise some objections about van Fraassen’s reliance on prior opinion and argue that the content of a belief matters to its rationality. In section 5, I criticise van Fraassen’s view that inference to the best explanation is incoherent. Finally, in section 6, I take on van Fraassen’s conception of rationality and show that it is too thin to fully capture rational judgement. (shrink)

c causes e iff i. c is spatiotemporally contiguous to e; ii. e succeeds c in time; and iii. all events of type C (i.e., events that are like c) are regularly followed by (or are constantly conjoined with) events of type E (i.e., events like e).

The recent debate around scientific realism has taken an epistemic turn. The issue is no longer whether theoretical discourse is or is not assertoric (truth-valuable), nor whether theoretical discourse can be reduced to observational discourse. All sides of the present debate have left behind traditional instrumentalism and reductive empiricism. Instead, they endorse semantic realism which suggests that theoretical discourse (that is, statements about theoretical entities) should be understood literally and be taken to be assertoric and irreducible. In this setting, the (...) philosophical reaction to realism challenges the grounds for the realists’ belief in the existence of the unobservable entities posited by theories and in the truth of the assertions made about them. This reaction can take different shapes. But the dominant one, coming from van Fraassen’s constructive empiricism, is that an empiricist cannot be rationally forced to be a scientific realist. In his view, an empiricist can understand scientific theories literally but remain agnostic as to the truth (or falsity) of their theoretical assertions. Besides, if an empiricist decides to accept a theory he accepts it not as true but as empirically adequate. (shrink)

This paper aims to cast light on the reasons that explain the shift of opinion—from scepticism to realism—concerning the reality of atoms and molecules in the beginning of the twentieth century, in light of Jean Perrin’s theoretical and experimental work on the Brownian movement. The story told has some rather interesting repercussions for the rationality of accepting the reality of explanatory posits. Section 2 presents the key philosophical debate concerning the role and status of explanatory hypotheses c. 1900, focusing on (...) the work of Duhem, Stallo, Ostwald, Poincaré and Boltzmann. Section 3 examines in detail Perrin’s theoretical account of the molecular origins of Brownian motion, reconstructs the structure and explains the strength of Perrin’s argument for the reality of molecules. Section 4 draws three important lessons for the current debate over scientific realism. (shrink)

Rani Lill Anjum and Stephen Mumford have recently defended a new kind of modality, which they call ‘dispositional modality’. The key reason to adopt dispositional modality, according to them, is that causes never necessitate their effects. Anjum and Mumford’s chief argument against causal necessitation makes use of what they call the ‘antecedent-strengthening test’ : C causally necessitates E iff C & φ causes E, for any possible φ. This test, they claim, fails in all cases of alleged causal necessitation. In (...) this paper we argue that the AS-test is not the mark of causal necessitation. First, we show that if the AS-test is taken as the mark of causal necessitation it leads to either an absurdity or to circularity. Second, we argue that, given the Mill/Mackie framework of causes as INUS conditions, apparent counterexamples to causal necessitation fail. (shrink)

Subjective Bayesianism is the current orthodoxy in confirmation theory. In broad outline, this view claims a) that confirmation is a relation of positive relevance, viz., that a piece of evidence confirms a theory if it increases its probability; b) that this relation of confirmation is captured by Bayes’s theorem; c) that, hence, the only factors relevant to confirmation of a theory are its prior probability, the likelihood of the evidence given the theory and the probability of the evidence; d) that (...) the specification of the prior probability of a theory is a purely subjective matter; e) that the only constraint on an assignment of prior probabilities to several theories should be that they obey the axioms of the probability calculus; f) that, hence, the reasonableness of a belief does not depend on its content; nor, ultimately, on whether the belief is made reasonable by the evidence; and g) that degrees of belief are probabilities and that belief is always a matter of degree. This theory has had many successes. Old tangles, like the ravens paradox or the grue problem, are resolved. New tangles, like the problem of old evidence, have been, to some extent, resolved. But there is still a pervasive dissatisfaction with subjective Bayesianism. This dissatisfaction concerns all of the theses to above, but it is centred mostly around the point that subjective Bayesianism is too subjective to offer an adequate theory of confirmation and of rational belief. Yet, up until recently this dissatisfaction had not borne fruits in a fully developed alternative theory of confirmation. Perhaps, only Deborah Mayo’s error-statistical approach was a fully developed alternative, but this too faced considerable problems, one central among them being that she takes all probabilities to be relative frequencies. One thing is sure. Probability theory should place a central role in a theory of confirmation. But how are we to interpret probabilities if we want to avoid the subjective element of Bayesianism and the objective element of the error-statistical approach? (shrink)

Scientific realism is the optimistic view that modern science is on the right track: that the world really is the way our best scientific theories describe it. In his book, Stathis Psillos gives us a detailed and comprehensive study which restores the intuitive plausibility of scientific realism. We see that throughout the twentieth century, scientific realism has been challenged by philosophical positions from all angles: from reductive empiricism, to instrumentalism and to modern sceptical empiricism. _Scientific Realism_ explains that the (...) history of science does not undermine the arguments for scientific realism, but instead makes it reasonable to accept scientific realism as the best philosophical account of science, its empirical success, its progress and its practice. Anyone wishing to gain a deeper understanding of the state of modern science and why scientific realism is plausible, should read this book. (shrink)

This paper is structured around the three elements of the title. Section 2 claims that (a) structures need objects and (b) scientific structuralism should focus on in re structures. Therefore, pure structuralism is undermined. Section 3 discusses whether the world has `excess structure' over the structure of appearances. The main point is that the claim that only structure can be known is false. Finally, Section 4 argues directly against ontic structural realism that it lacks the resources to accommodate causation within (...) its structuralist slogan. (shrink)

This paper examines in detail two paths that lead to Structural Realism, viz. a substantive philosophical position which asserts that only the structure of the world is knowable. The upward path is any attempt to begin with empiricist premises and reach a sustainable realist position. The downward path is any attempt to start from realist premises and construct a weaker realist position. This paper unravels and criticizes the metaphysical presuppositions of both paths to SR. It questions its very possibility as (...) a substantive—and viable—realist thesis. (shrink)

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

ABSTRACT I discuss Nadia Urbinati's argument by highlighting an alternative dimension of populism, one that departs from the same assumptions but reaches a different understanding: populism as an antisystem electoralist strategy, one that is part of the technology of democratic competition.

A great deal of violence in civil wars is informed by the logic of terrorism: violence tends to be used by political actors against civilians in order to shape their political behavior. I focus on indiscriminate violence in the context of civil war: this is a type of violence that selects its victims on the basis of their membership in some group and irrespective of their individual actions. Extensive empirical evidence suggests that indiscriminate violence in civil war is informed by (...) the logic of terrorism. I argue that under certain conditions, that tend to be quite common, such violence is counter productive. I specify these conditions and address the following paradox: why do we sometimes observe instances of indiscriminate violence evenunder conditions that make this strategy counterproductive? I review four possible reasons: truncated data, ignorance, cost, and institutional constraints. I argue that indiscriminate violence emerges because it is much cheaper than its main alternative – selective violence. It is more likely under a steep imbalance of power between the competing actors, and where and when resources and information are low; however, most political actors eventually switch to selective violence. Thus, given a balance of power between competing actors, indiscriminate violence is more likely at early rather than late stages of the conflict. Overall, the paper suggests that even extreme forms of violence are used strategically. (shrink)

The paper offers an account of how the meaning of the concept of “invention” and “inventorship” is not stable and predefined but rather constructed during patent disputes. In particular, I look at how that construction takes place in adversarial settings like the courts of law. I argue that key notions of intellectual property law like invention and inventorship are as constructed as technoscientific claims are in laboratories. Courts should thus be seen as sites of construction through processes framed by specific (...) discursive and evidentiary technologies like bureaucratic paperwork, literary technologies, historiographic accounts of inventorship, and models of artifacts and devices. I draw my examples from the British disputes of the Marconi Company concerning the patenting of wireless telegraph and radio communication technologies in the first half of the twentieth century. The paper tracks Marconi’s circulation of publications, models, historical reconstruction of inventions, and expert witnessing. It unravels the material, discursive, textual, and evidentiary constructions of legality. (shrink)

Cornelius Castoriadis's theory of sublimation is not only innovative within the Freudian tradition, but opens up the domain of inquiry as to society's process of radical social institution. Sublimation is indeed socialization, not merely aesthetic cathexis. A specific sort of sublimation that may be said to mobilize the project of autonomy is linked to philosophy both because it is implicated in a process of interminable interrogation, and because it involves the psyche's practical and poetic engagement with the creation of new (...) imaginary forms. Philosophy's task, in this sense, is to consider thought from the standpoint of the unthought, a daring task that cannot ultimately take place without one's fully-fledged acceptance of one's own finitude.

The theoretical problem Bensaïd tries to confront from the 1990s onwards is the problem of the categories that are necessary to account for the traumatically new experience of history opened up by the defeat of the revolutionary experiments of the twentieth century. Hence the necessity of new answers to these fundamental and inexhaustible questions: How are we to understand history in its relation to human practice and to politics? Can we talk of ‘necessity’ in history, of ‘laws of history’, of (...) ‘determination’, or ‘determinism’, or of modes of causality operating within it? How are we to conceive the notions of ‘historical possibility’, of ‘conflict’ and ‘struggle’? Bensaïd’s contribution will focus on a dialectical notion of temporality that implies a primacy of politics over history and a break with the traditional Marxist notions of a historical subject as an internally homogeneous and fully-sovereign collective force.

This article deals with a question of a most general, comprehensive and profound content as it is the nature of mathematical–logical objects insofar as these are considered objects of knowledge and more specifically objects of formal mathematical theories. As objects of formal theories they are dealt with in the sense they have acquired primarily from the beginnings of the systematic study of mathematical foundations in connection with logic dating from the works of G. Cantor and G. Frege in the last (...) decades of the nineteenth century. Largely motivated by a phenomenologically founded view of mathematical objects/states-of-affairs, I try to consistently argue for their character as objects shaped to a certain extent by intentional forms exhibited by consciousness and the modes of constitution of inner temporality and at the same time as constrained in the form of immanent ‘appearances’ by what stands as their non-eliminable reference, that is, the world as primitive soil of experience and the mathematical intuitions developed in relations of reciprocity within-the-world. In this perspective and relative to my intentions I enter, in the last section, into a brief review of certain positions of G. Sher’s foundational holism and R. Tieszen’s constituted platonism, among others, respectively presented in Sher and Tieszen. (shrink)

This article attempts a subjectively based approach, in fact one phenomenologically motivated, toward some key concepts of forcing theory, primarily the concepts of a generic set and its global properties and the absoluteness of certain fundamental relations in the extension to a forcing model M[G]. By virtue of this motivation and referring both to the original and current formulation of forcing I revisit certain set-theoretical notions serving as underpinnings of the theory and try to establish their deeper subjectively founded content (...) and also their influence in reaching relative consistency results by the forcing method. In this perspective, the present approach may be seen as offering an alternative view of the consistency results of K. Gödel and P. Cohen in mathematical foundations reaching a subjective level that may be taken as ultimately conditioning the non-decidability of key infinity statements on the level of formal theory. (shrink)

When we philosophers think about causation we are primarily interested in what causation is – what exactly is the relation between cause and effect? Or, more or less equivalently, how and in virtue of what is the cause connected to the effect? But we are also interested in an epistemic issue, viz., the possibility of causal knowledge: how, if at all, can causal knowledge be obtained? The two issues are, of course, conceptually distinct – but to many thinkers, there is (...) a connection between them. A metaphysical account of causation would be useless if it did not make, at least in principle, causal knowledge possible. Conversely, many philosophers, mostly of an empiricist persuasion, have taken the possibility of causal knowledge to act as a constraint on the metaphysics of causation: no feature that cannot in principle become the object of knowledge can be attributed to causation.

In this article my primary intention is to engage in a discussion on the inherent constraints of models, taken as models of theories, that reaches beyond the epistemological level. Naturally the paper takes into account the ongoing debate between proponents of the syntactic and the semantic view of theories and that between proponents of the various versions of scientific realism, reaching down to the most fundamental, subjective level of discourse. In this approach, while allowing for a limited discussion of physical (...) and positive science models, I am primarily focused on the structure and ontology of mathematical models, in particular Cohen’s forcing models and to a lesser extent Gödel’s constructible universe, to the extent that these were designed to answer questions bearing on the scope, the capacity and ultimately the ontology of models themselves, therefore influencing in one or the other way the status of models in general. This status, it is argued, is largely defined by the way models subsume a set-theoretical structure whose constraints, reducible to an extra-linguistic level of discourse, may implicitly condition the epistemic status of models as representations of axiomatic theories. In the last section I deal extensively with the inner constraints of theories as subjectively originated in a less technical philosophically oriented discussion with certain prompts from phenomenology.

Enlightenment thought is widely considered to consist of four key features--atheism, democracy, humanism, and modernity. Common to all is an explicit process of desacralization. Yet the intellectual history of these concepts reveals that in the process of desacralization new sacred spaces arose in their name. The aim of Nothing Sacred is to question this second-order sacralization and consider, in a form of negative dialectics, whether (and how) these domains can argue against themselves in order to once again desacralize their own (...) self-sacralization. Secular critique is not simply an attack on religion but rather on the range of society's unavowed self-occlusions. Its object is to elucidate the politics and practices of knowledge that animate them. In the field of religion critique challenges the alleged permanence of political theology and transforms the epistemologies of both sacred and secular. For Stathis Gourgouris the state of nature that he terms political animality critiques political theology much as the anarchy of democracy, inhabited by it, critiques sovereignty. He takes aim at the desacralizing capacity of these historical formations, which produce their own historical conditions for self-sacralization, in order to demonstrate their dynamic subversive power against deeply ensconced conditions of disempowerment and incapacitation and to understand how societies and individuals are driven to self-subversion and self-disempowerment. These forces are alive today in the form of discursive "posts"--posthumanism, postdemocracy, post-truth, postracial--which are just as self-sacralizing. Exposing them is not a nostalgic liberal return to an idealized past but an expansive anarchic ontological affirmation of the political dimensions of human animality on a planetary scale and of a radical politics in which democracy has severed its bind to capitalism. Nothing Sacred thinks across orders, obstacles, and intersectional spaces in a world of warring multipolar oligarchies and psychotic rage. (shrink)
