The paper addresses the question of how the unity of science can adequately be characterized. A mere classification of scientific fields and disciplines does not express the unity of science unless it is supplemented with a perspective that establishes a systematic coherence among the different branches of science. Four ideas of this kind are discussed. Namely, the unity of scientific language, of scientific laws, of scientific method and of science as a practical‐operational enterprise. Whereas reference to the unity of scientific (...) language and of scientific laws does not provide a viable basis for the unity of science, the methodological and practical unity might. The unity of science can be characterized by the way in which methodological criteria enter into the assessment or evaluation of theories, and, moreover, by a transdisciplin‐ary approach to problems. Accordingly, the unity of science is not expressed by theoretical uniformity but by the unity of scientific practice. (shrink)

Empiricists mostly prefer an epistemic notion of causality intending thereby to avoid metaphysical entanglements. General relativity however provides examples for causality without predictability, i. e. world models in which for geometrical reasons there exist no spacelike hypersurfaces containing traces of all future events. Yet local determinism for every single event remains valid in these cases. Therefore the problem arises how to account for a causal structure that implies local but not global predictability. This problem, it is argued, cannot be solved (...) by characterizing the causal connection of events itself by means of its epistemic aspects. Instead the ontological ground must be emphazised which allows for varying epistemic properties of causal connections according to the space-time structure. This can be done by use of the energy transfer concept of causality which involves no reminiscence of dubious natural necessity. (shrink)

Epistemologists generally think that genuine warrant that is available to anyone must be available to everyone who is exposed to the relevant causal inputs and is able and willing to properly exercise her rationality. The motivating idea behind this requirement is roughly that an objective view is one that is not bound to a particular perspective. In this paper I ask whether the aperspectivality of our warrants is a precondition for securing the objectivity of our claims. I draw upon a (...) Sellarsian account of perception in order to argue that it is not; rather, inquirers can have contingent properties and perspectives that give them access to forms of rational warrant and objective knowledge that others do not have. The universal accessibility of reasons, on my account, is not a precondition for the legitimacy of any actual warrant, but rather a regulative ideal governing inquiry and communication. (shrink)

According to manipulationist accounts of causal explanation, to explain an event is to show how it could be changed by intervening on its cause. The relevant change must be a ‘serious possibility’ claims Woodward 2003, distinct from mere logical or physical possibility—approximating something I call ‘scientific possibility’. This idea creates significant difficulties: background knowledge is necessary for judgments of possibility. Yet the primary vehicles of explanation in manipulationism are ‘invariant’ generalisations, and these are not well adapted to encoding such knowledge, (...) especially in the social sciences, as some of it is non-causal. Ceteris paribus (CP) laws or generalisations labour under no such difficulty. A survey of research methods such as case and comparative studies, randomised control trials, ethnography, and structural equation modeling, suggests that it would be more difficult and in some instances impossible to try to represent the output of each method in invariant generalisations; and that this is because in each method causal and non-causal background knowledge mesh in a way that cannot easily be accounted for in manipulationist terms. Ceteris paribus-generalisations being superior in this regard, a theory of explanation based on the latter is a better fit for social science. (shrink)

This thesis offers a naturalist revision of Alain Badiou’s philosophy. This goal is pursued through an encounter of Badiou’s mathematical ontology and theory of truth with contemporary trends in philosophy of mathematics and philosophy of science. I take issue with Badiou’s inability to elucidate the link between the empirical and the ontological, and his residual reliance on a Heideggerian project of fundamental ontology, which undermines his own immanentist principles. I will argue for both a bottom-up naturalisation of Badiou’s philosophical approach (...) to mathematics and a top-down naturalisation. Articulating my particular understanding of what realism and naturalism should commit us to, I propose a creative fusion of Badiou’s attention to metamathematical results with a structural-informational metaphysics, proposing a ‘matherialism’ uniting the more daring speculative insights of the former with the naturalist and empiricist commitments motivating the latter.

Assuming that the qualities of immediate experience ('sentience') are the subjective aspect of the neurophysiological cerebral processes, And assuming that all behavior is ultimately susceptible to physical explanation, There are a number of ways in which mind-Body monism can be stated. But there are also a number of serious difficulties for a logically coherent formulation of the identity thesis of the mental and the physical.

Rudolf Carnap is well known for his attack on metaphysics, and W. V. Quine is equally well known for his attack on Carnap’s analytic/synthetic distinction. Receiving far less attention is their basic agreement that a properly scientific approach to philosophy should eliminate the metaphysical excesses of the past. This paper aims to remedy this. It focuses initially on the development of Carnap’s rejection of metaphysics from 1932 to 1950 and the role that analyticity plays. It then turns to Quine, emphasizing (...) his basic agreement with Carnap over the elimination of metaphysics and what this looks like without the analytic/synthetic distinction. (shrink)

Philosophy of science was once a much more socially engaged endeavor, and can be so again. After a look back at philosophy of science in the 1930s-1950s, I turn to discuss the current potential for returning to a more engaged philosophy of science. Although philosophers of science have much to offer scientists and the public, I am skeptical that much can be gained by philosophers importing off-the-shelf discussions from philosophy of science to science and society. Such efforts will likely look (...) like efforts to do applied ethics by merely applying ethical theories to particular contexts and problems. While some insight can be gained by these kinds of endeavors, the most interesting and pressing problems for the actual practitioners and users of science are rarely addressed. Instead, I recommend that philosophers of science engage seriously and regularly with scientists and/or the users of science in order to gain an understanding of the conceptual issues on the ground. From such engagement, flaws in the traditional philosophical frameworks, and how such flaws can be remedied, become apparent. Serious engagement with the contexts of science thus provides the most fruit for philosophy of science per se and for the practitioners whom the philosophers aim to assist. And if one focuses on contexts where science has its most social relevance, these efforts can help to provide the thing that philosophy of science now lacks: a full-bodied philosophy of science in society.

After a brief review of ontic and epistemic descriptions, and of subjective, logical and statistical interpretations of probability, we summarize the traditional axiomatization of calculus of probability in terms of Boolean algebras and its set-theoretical realization in terms of Kolmogorov probability spaces. Since the axioms of mathematical probability theory say nothing about the conceptual meaning of “randomness” one considers probability as property of the generating conditions of a process so that one can relate randomness with predictability (or retrodictability). In the (...) measure-theoretical codification of stochastic processes genuine chance processes can be defined rigorously as so-called regular processes which do not allow a long-term prediction. We stress that stochastic processes are equivalence classes of individual point functions so that they do not refer to individual processes but only to an ensemble of statistically equivalent individual processes. Less popular but conceptually more important than statistical descriptions are individual descriptions which refer to individual chaotic processes. First, we review the individual description based on the generalized harmonic analysis by Norbert Wiener. It allows the definition of individual purely chaotic processes which can be interpreted as trajectories of regular statistical stochastic processes. Another individual description refers to algorithmic procedures which connect the intrinsic randomness of a finite sequence with the complexity of the shortest program necessary to produce the sequence. Finally, we ask why there can be laws of chance. We argue that random events fulfill the laws of chance if and only if they can be reduced to (possibly hidden) deterministic events. This mathematical result may elucidate the fact that not all nonpredictable events can be grasped by the methods of mathematical probability theory. (shrink)

Considering the instability of nonlinear dynamics, the deductive inference rule Modus ponens itself is not enough to guarantee the validity of reasoning sequences in the real physical world, and similar results cannot necessarily be obtained from similar causes. Some kind of stability hypothesis should be added in order to draw meaningful conclusions. Hence, the uncertainty of deductive inference appears to be like that of inductive inference, and the asymmetry between deduction and induction becomes unrecognizable such as to undermine the basis (...) for the fundamental cleavage between analytic truth and synthetic truth, as W. V. O. Quine pointed out. Induction is not inferior to deduction from a pragmatic point of view. (shrink)

As microeconomic calculus and macroeconomic estimation superseded earlier approaches to political economy, broad questions about how things are (ontology), how things might be known (epistemology), and how science should proceed (methodology) were neglected. As a corrective, Critical Realism (CR) has been proposed as an alternative to the orthodox deductive‐nomological (ODN) tradition; i.e., to mathematical deduction and statistical induction. In their place, retroduction—the use of analogy, metaphor, intuition and ordinary language—is supposed to illuminate root causes by identifying the deep mechanisms that (...) govern events. CR offers guidelines for social science that are of a most general kind: from initial “premises,” retroduction proceeds to hypotheses about deep structures and mechanisms. The initial premises are determined by a desire to understand events that surprise us. However, nothing is thereby excluded, including ODN. And since historical processes are revealed neither by assumption nor by the net effects of whatever initial conditions hold, it might be apposite to drop the search for (deep) socio‐economic laws and to use whatever evidence is at hand to see whether, and the extent to which, ideal types apply to any given historical sequence.

The basic (negative and positive) methodological maxims of three currents of philosophy of science (logical empiricism, falsificationism, and postpositivism) are formulated. Many of these maxims (stratagems) are controversial, e.g., the stance about the nonsense of metaphysics, and that of its indispensability. The restricted validity of these maxims allows for their unification. Within the framework of most of them there may be a relationship of (synchronic, or diachronic) subordination of the contradicting desiderata. In this vein ten stratagems are formulated.

We investigate the way physical laws objectively refer to the entities they are about. Laws of mathematical physics do not refer directly to the “real world” but to an ideal specific domain of objects, which we term “scope”. In order to find out which real objects physical laws deal with, reference to the scope is not sufficient. We need in addition the search for domains to which laws apply — i. e. “empirical domains”— in order to establish their reference to (...) the “real world”. It is just in such empirical domains that we are able to discover the real entities physical laws objectively refer to. “Physical reality” turns out to be not something “given” but rather something “to come out” of the very process of scientific inquiry.

Abstract In the philosophical literature, there are two common criteria for a physical theory to be deterministic. The older one is due to the logical empiricists, and is a purely formal criterion. The newer one can be found in the work of John Earman and David Lewis and depends on the intended interpretation of the theory. In this paper I argue that the former must be rejected, and something like the latter adopted. I then discuss the relevance of these points (...) to the current debate over the hole argument.

Reseña de libro: Reisch, George, Cómo la guerra fría transformó la filosofía de la ciencia. Hacia las heladas laderas de la lógica. Buenos Aires, Argentina, Universidad Nacional de Quilmes Editorial.

CONTEMPORARY MATERIALIST theories of mind, viz. Causal Correspondence and Identity, are usually contrasted with several alleged historical competitors: Parallelism; Epiphenomenalism; Dual-aspect; and Emergence. What I shall here attempt to argue is that this last-mentioned theory, Emergence, is no competitor at all, but rather is a natural supplement to a materialist theory. I shall try to argue that there is a good case for saying that if, in particular, sensation-states are caused by or are identical to brain-states, then they are caused (...) by or are identical to emergent brain-states.

A recently formulated concept of stochastic localizability is shown to be consistent with a concept of stochastic microcausality, which avoids the conclusions of Hegerfeldt's no-go theorem as to the inconsistency of sharp localizability of quantum particles and Einstein causality. The proposed localizability on quantum space-time is shown to lead to strict asymptotic causality. For finite time evolutions, upper bounds on propagation to the exterior of stochastic light cones are derived which show that the resulting probabilities are too small to be (...) actually observable in a realistic context.

The purpose of this essay is to defend the deductive-nomological model of explanation against a number of criticisms that have been made of it. It has traditionally been thought that scientific explanations were causal and that scientific explanations involved deduction from laws. In recent years, however, this three-fold identity has been challenged: there are, it is argued, causal explanations that are not scientific, scientific explanations that are not deductive, deductions from laws that are neither causal explanations nor scientific explanations, and (...) causal explanations that involve no deductions from laws. The aim of the present essay is to defend the traditional identities, and to show that the more recent attempts at invalidating them fail in their object. More specifically, this essay argues that a Humean version of the deductive-nomological model of explanation can be defended as the correct account of scientific explanation of individual facts and processes, and as the correct account of causal explanations of individual facts and processes. The deductive-nomological model holds that to explain an event E, say that a is G, one must find some initial conditions C, say that a is F, and a law or theory T such that T and C jointly entail E, and both are essential to the deduction.

Celem artykułu jest ukazanie specyfiki filozoficznej refleksji nad historią. W tym kontekście istotne staje się przedstawienie pojęć, którymi określa się ten rodzaj refleksji, a także obejmowany przez nią zakres problemowy. Filozofię dziejów, historiozofię i filozofię historii, należy więc rozpatrywać z konkretnej perspektywy badawczej, chociaż w potocznym rozumieniu pojęcia te stosowane są zamiennie.
