The operation of developing a concept is a common procedure in mathematics and in natural science, but has traditionally seemed much less possible to philosophers and, especially, logicians. Meir Buzaglo's innovative study proposes a way of expanding logic to include the stretching of concepts, while modifying the principles which block this possibility. He offers stimulating discussions of the idea of conceptual expansion as a normative process, and of the relation of conceptual expansion to truth, meaning, reference, ontology and (...) paradox, and analyzes the views of Kant, Wittgenstein, Godel, and others, paying especially close attention to Frege. His book will be of interest to a wide range of readers, from philosophers to logicians, mathematicians, linguists, and cognitive scientists. (shrink)

The philosophy of Solomon Maimon is usually considered an important link between Kant’s transcendental philosophy and German idealism. Highly praised during his lifetime, over the past two centuries Maimon’s genius has been poorly understood and often ignored. Meir Buzaglo offers a reconstruction of Maimon’s philosophy, revealing that its true nature becomes apparent only when viewed in light of his philosophy of mathematics. This provides the key to understanding Maimon’s solution to Kant’s _quid juris_ question concerning the connection between (...) intuition and concept in mathematics. Maimon’s original approach avoids dispensing with intuition while reducing the reliance on intuition in its Kantian sense. As Buzaglo demonstrates, this led Maimon to question Kant’s ultimate rejection of the possibility of metaphysics and, simultaneously, to suggest a unique type of skepticism. (shrink)

According to a common view, belief in God cannot be proved and is an issue that must be left to faith. Kant went even further and argued that he can prove this unprovability. But any argument implying that a certain sentence is not provable is challenged by Gödel’s second theorem. Indeed, one trivial consequence of GST is that for any formal system F that satisfies certain conditions and for every sentence K that is formulated in F it is impossible to (...) prove, from F, that K is not provable. In the article, I explore the general issue of proving the unprovability of the existence of God. Of special interest is the question of the relation between the existence of God and the conditions that F must satisfy in order to allow for its subjection to GST. (shrink)

Philosophical analysis is for Quine the replacement of a defective expression by another, sound expression, which performs the same work. In general, then, an analysis consists of two stages: (a) identifying the work that a defective expression performs, and (b) imbedding it in a safe domain. In this essay I argue that Quine’s view does not truly reflect what we do in philosophy. The problem, I think, lies in both stages (a) and (b), but stems from Quine’s assumption that we (...) can control the work performed by language. (shrink)

This paper describes a version of type identity physicalism, which we call Flat Physicalism, and shows how it meets several objections often raised against identity theories. This identity theory is informed by recent results in the conceptual foundations of physics, and in particular clar- ifies the notion of ‘physical kinds’ in light of a conceptual analysis of the paradigmatic case of reducing thermody- namics to statistical mechanics. We show how Flat Physi- calism is compatible with the appearance of multiple realisation (...) in the special sciences, and how and in what sense the special sciences laws are autonomous from the laws of physics, despite the full reductive picture of Flat Physicalism. We compare our view with a recent proposal by William Bechtel that accounts for the appearance of levels in mechanistic explanations. (shrink)

Jewish business ethics in Israel addresses two major sources of economic immorality—unbounded desire and fear of economic uncertainty—through enforcement and spiritual education. Business is seen as a path to sanctity, when time is set apart for religious study, wealth is seen as originating from God, the vulnerable are protected against fraud and theft, charity is seen as an obligation, and mercy towards debtors is tempered by justice.

This article exploits the unique consequences of the COVID-19 pandemic outbreak to examine whether time constraints drive the unequal division of unpaid labor between dual-earner couples in Israel. Using the first wave of longitudinal household data that was collected in Israel since the outbreak of the pandemic, we focused on 325 dual-earner couples who stayed employed during the first lockdown. By employing OLS regressions, we examined the association between changes in employment hours and changes in unpaid labor for partnered men (...) and women. Strong evidence was found for a gendered translation of the time constraints mechanism: A decrease in hours of paid work is related to an increase in hours of care for children among men and women, but time devoted to housework increased only among women. We conclude that time constraints that resulted from the dramatic effect of the first lockdown on paid and unpaid work in Israel did not significantly change the gender division of unpaid housework but did change the distribution of childcare. The theoretical implications of this conclusion for future research are discussed. (shrink)

The topic of my essay is Palestinian morgue photography in the wake of the Israeli air strikes and the ground invasion of Gaza, during Operation Cast Lead. I especially focus on a fashionable angle that is prevalent among the local Palestinian press-photographers. I term it the acrobatic gaze: from the heights of the fridges in the morgue the photographers try to be omniscient absently-present witnesses that are capable of combining in a single composition both the faces of the standing relatives (...) and the faces of the supine bodies. These photographs raise ethical, aesthetical, and political questions about the representation of the dead who are displayed to their families and to the photographers for propaganda reasons as well.

This article examines the grappling of modern positivists with the question of legal unity. It presents and contrasts two antagonistic positivist strands—naturalist and normativist—epitomized in the works of Austin and Kelsen, respectively. The two strands correspond to two contrasting models of legal authority—criterial and coherence-based—and they accordingly diverge on the proper explanation of unity. Naturalist, criterial models purport to explain the unity of law based on extra-legal facts alone; normativist, coherence-based models resort strictly to the interrelation of legal elements themselves. (...) Against this backdrop, the article argues that Raz’s work on the subject is torn between Austin and Kelsen: While his naturalist ancestors accounted for legal unity externally, Raz’s prominent works are captivated by the Kelsenian realization that the unity of law must be accounted for internally. Two central upshots follow. First, the analysis provides a litmus test for the (in)ability of naturalist positivism to explain legal unity. Second, Raz’s strategic reliance on Kelsen distorts his work: Both the Grundnorm and validity chains are upended to fit Raz’s naturalist commitments. (shrink)

Poland has produced two of the greatest economists of the past century, namely Michal Kalecki and Oskar Lange. Both worked with a wide and penetrating view of the economy and society, more typical of the great classical economists than of those of their own time. During the post-World War II 'Golden Age of Growth', while Keynes was the patron saint of economic theory and policy in the industrialised capitalist countries, Kalecki and Lange had a similar influence and role among the (...) developing nations and – perhaps to a lesser extent – in socialist countries. Kalecki's 'The problem of financing of economic development' (Kalecki, 1954), and Lange's 'Some observations on input-output analysis' (Lange, 1957), in particular,deeply influenced the approach to economic and social development of a whole strand of structural economics, both in terms of economic analysis and practical policy. With the end of the Golden Age and the momentous neoliberal reaction then started, they became almost forgotten. The economics of Kalecki, however, has inspired in the last few decades the renaissance of a genuine – albeit still marginal(ised) – form of Keynesianism, the so called 'post-Keynesianism' ('bastard Keynesianism', as Joan Robinson called it, being the dominant, mainstream form of Keynesianism). Oskar Lange, on the other hand, does not yet seem to have been re-discovered to inspire a similar renaissance of advanced analysis and planning of policies for modern structural change and development. This paper proposes such a re-discovery. The main concern of Lange's 'Observations' is the appropriate intersectoral allocation of investment for efficient output growth. While output growth is still one of the main objectives in most societies, the growth of human capabilities should be an increasingly relevant concern, both in its own right, and in view of the existing ecological constraints. Buzaglo (2014a; b) postulated the existence of an  (aleph) matrix, describing the proportions of the different capabilities necessary for the achievement of every particular capability. The present paper is about introducing capabilities within Lange's framework of analysis. A Lange-inspired analysis investigates the appropriate structures and properties of capability-enhancing growth paths. (shrink)

According to influential views the probabilities in classical statistical mechanics and other special sciences are objective chances, although the underlying mechanical theory is deterministic, since the deterministic low level is inadmissible or unavailable from the high level. Here two intuitions pull in opposite directions: One intuition is that if the world is deterministic, probability can only express subjective ignorance. The other intuition is that probability of high-level phenomena, especially thermodynamic ones, is dictated by the state of affairs in the world. (...) We argue in support of this second intuition and we show that in fact there are two different ways in which high-level probability describes matters of fact, even if the underlying microscopic reality is deterministic. Our analysis is novel, but supports approaches by, e.g., Loewer, Albert, Frigg and Hoefer, List and Pivato. In particular, the reductive view we propose here can be seen as a naturalization of the above approaches. We consider consequences of our result for nonreductive physicalist approaches, such as functionalism, that admit multiple realization of the kinds that appear in the special sciences by physical kinds. We show that nonreductive physicalism implies the existence of nonphysical matters of fact. (shrink)

This paper makes a novel linkage between the multiple-computations theorem in philosophy of mind and Landauer’s principle in physics. The multiple-computations theorem implies that certain physical systems implement simultaneously more than one computation. Landauer’s principle implies that the physical implementation of “logically irreversible” functions is accompanied by minimal entropy increase. We show that the multiple-computations theorem is incompatible with, or at least challenges, the universal validity of Landauer’s principle. To this end we provide accounts of both ideas in terms of (...) low-level fundamental concepts in statistical mechanics, thus providing a deeper understanding of these ideas than their standard formulations given in the high-level terms of thermodynamics and cognitive science. Since Landauer’s principle is pivotal in the attempts to derive the universal validity of the second law of thermodynamics in statistical mechanics, our result entails that the multiple-computations theorem has crucial implications with respect to the second law. Finally, our analysis contributes to the understanding of notions, such as “logical irreversibility,” “entropy increase,” “implementing a computation,” in terms of fundamental physics, and to resolving open questions in the literature of both fields, such as: what could it possibly mean that a certain physical process implements a certain computation.

This paper proves that Maxwell's Demon is compatible with classical mechanics. In particular it shows how the cycle of operation - including measurement and erasure - can be carried out with no entropy cost, contrary to the Landauer-Bennett thesis (according to which memory erasure costs kln2 of entropy increase per bit). The Landauer-Bennet thesis is thus proven to be mistaken.

Special sciences (such as biology, psychology, economics) describe various regularities holding at some high macroscopic level. One of the central questions concerning these macroscopic regularities is how they are related to the laws of physics governing the underlying microscopic physical reality. In this paper we show how a macroscopic regularity may emerge from an underlying micro- scopic structure, and how the appearance of multiple realizability of the special sciences by physics comes about in a reductionist-physicalist framework. On this basis we (...) explain how complexity at the high level can arise due to a sort of harmony between the microscopic dynamics and observer-dependent macroscopic properties. We show that observer-dependent properties, which underlie the emergence of macroscopic properties and of macroscopic complexity, are objective physical facts. We argue that such physical properties remove the mystery from the multiple realizability of special sciences’ kinds, since the latter are grounded in shared physical properties. Finally we explain how and in what sense in our reductive physicalist approach the special sciences are still autonomous after all. (shrink)

Can the second law of thermodynamics explain our mental experience of the direction of time? According to an influential approach, the past hypothesis of universal low entropy also explains how the psychological arrow comes about. We argue that although this approach has many attractive features, it cannot explain the psychological arrow after all. In particular, we show that the past hypothesis is neither necessary nor sufficient to explain the psychological arrow on the basis of current physics. We propose two necessary (...) conditions on the workings of the brain that any account of the psychological arrow of time must satisfy. And we propose a new reductive physical account of the psychological arrow of time compatible with time-symmetric physics, according to which these two conditions are also sufficient. Our proposal has some radical implications, for example, that the psychological arrow of time is fundamental, whereas the temporal direction of entropy increase in the second law of thermodynamics and the past hypothesis is derived from it, rather than the other way around. 1Introduction2A Physical Account of the Psychological Arrow of Time3Necessary Conditions for the Psychological Arrow of Time4The Psychological Arrow of Time via the Second Law of Thermodynamics and the Past Hypothesis5Why the Past Hypothesis Is Insufficient for the Psychological Arrow of Time5.1Stage 1, Version 1: From the past hypothesis to the psychological arrow via typicality5.2Stage 1, Version 2: From the past hypothesis to the psychological arrow via dynamical or causal considerations5.3Stage 2: From entropy gradient in the brain to the psychological arrow of time6Why the Past Hypothesis Is Unnecessary for the Psychological Arrow of Time7A New Reductive Account of the Psychological Arrow of Time.

In this paper we analyze the relation between the notion of typicality and the notion of probability and the related question of how the choice of measure in deterministic theories in physics may be justified. Recently it has been argued that although the notion of typicality is not a probabilistic notion, it plays a crucial role in underwriting probabilistic statements in classical statistical mechanics and in Bohm’s theory. We argue that even in theories with deterministic dynamics, like classical statistical mechanics (...) and Bohm’s theory, the notion of probability can be understood as fundamentally objective, and that it is the notion of probability rather than typicality that may have an explanatory value.

We show that the so-called Multiple-Computations Theorem in cognitive science and philosophy of mind challenges Landauer’s Principle in physics. Since the orthodox wisdom in statistical physics is that Landauer’s Principle is implied by, or is the mechanical equivalent of, the Second Law of thermodynamics, our argument shows that the Multiple-Computations Theorem challenges the universal validity of the Second Law of thermodynamics itself. We construct two examples of computations carried out by one and the same dynamical process with respect to which (...) Landauer’s principle implies contradictory predictions concerning the entropy increase. Our two examples are based on a weak version of the Multiple-Computations Theorem, which is quite uncontroversial, and therefore they amount to a clear refutation of the universal validity of Landauer’s Principle. We consider some responses to this argument that do not attempt to single out one computation over the others, and we show that they do not work. We further consider ways out of the argument by externalist approaches supporting the computational theory of the mind who propose that the interaction of a computing system with the environment is enough to select a single computation over the others. We show on physical grounds that this approach fails too. We then reverse the direction of our challenge and formulate a dilemma for supporters of the computational theory of the mind: they must reject the causal closure of physic; or else they must accept on a priori grounds that Landauer’s Principle and the Second Law of thermodynamics are not universally valid. Finally, we present our version of a type–type mind-brain identity theory called Flat Physicalism, which is based on the paradigm case of statistical mechanics, and we show that it circumvents the challenge from Landauer’s Principle and the Multiple-Computations Theorem and does not fall prey to our dilemma.

In this paper we address two problems in Boltzmann's approach to statistical mechanics. The first is the justification of the probabilistic predictions of the theory. And the second is the inadequacy of the theory's retrodictions.

This volume provides a broad perspective on the state of the art in the philosophy and conceptual foundations of quantum mechanics. Its essays take their starting point in the work and influence of Itamar Pitowsky, who has greatly influenced our understanding of what is characteristically non-classical about quantum probabilities and quantum logic, and this serves as a vantage point from which they reflect on key ongoing debates in the field. Readers will find a definitive and multi-faceted description of the major (...) open questions in the foundations of quantum mechanics today, including: Is quantum mechanics a new theory of (contextual) probability? Should the quantum state be interpreted objectively or subjectively? How should probability be understood in the Everett interpretation of quantum mechanics? What are the limits of the physical implementation of computation? The impact of this volume goes beyond the exposition of Pitowsky’s influence: it provides a unique collection of essays by leading thinkers containing profound reflections on the field. (shrink)

We discuss the meaning of probabilities in the many worlds interpretation of quantum mechanics. We start by presenting very briefly the many worlds theory, how the problem of probability arises, and some unsuccessful attempts to solve it in the past. Then we criticize a recent attempt by Deutsch to derive the quantum mechanical probabilities from the nonprobabilistic parts of quantum mechanics and classical decision theory. We further argue that the Born probability does not make sense even as an additional probability (...) rule in the many worlds theory. Our conclusion is that the many worlds theory fails to account for the probabilistic statements of standard (collapse) quantum mechanics. (shrink)
