The decision to undertake this volume was made in 1971 at Lake Como during the Varenna summer school ofthe Italian Physical Society, where Professor Leon Rosenfeld was lecturing on the history of quantum theory. We had long been struck by the unique blend of epistemological, histori cal and social concerns in his work on the foundations and development of physics, and decided to approach him there with the idea of publishing a collection of his papers. He responded enthusiastically, and (...) agreed to help us select the papers; furthermore, he also agreed to write a lengthy introduction and to comment separately on those papers that he felt needed critical re-evaluation in the light of his current views. For he was still vigorously engaged in both theoretical investigations of, and critical not reflections on the foundations of theoretical physics. We certainly did conceive of the volume as a memorial to a 'living saint', but rather more practically, as a useful tool to place in the hands of fellow workers and students engaged in wrestling with these difficult problems. All too sadly, fate has added a memorial aspect to our labors. We agreed that in order to make this book most useful for the con temporary community of physicists and philosophers, we should trans late all non-English items into English. (shrink)

In this paper we consider the prehistory of quantum gravity (1916–1930) from two perspectives. First, we investigate how this research field constituted itself and we propose for the first time a red thread to trace its evolution in this earliest period. Second, we focus on a case study: the earliest work of Léon Rosenfeld. In 1927 he tried to merge wave mechanics with general relativity in the context of a five‐dimensional universe. We describe how Oskar Klein, Louis de (...) Broglie, and Théophile De Donder influenced Rosenfeld's work and analyze how and why Rosenfeld attempted to reconcile Einstein's theory with quantum phenomena. We argue that Rosenfeld investigated for the first time the corrections to a classical space‐time metric generated by a quantum source. As far as we know, Rosenfeld's approach has been largely ignored until today: he himself considered it “an accident.” After having reconsidered its connection with de Broglie's ideas and Rosenfeld's interpretation of the wave function in 1927, we argue that Rosenfeld's work can be interpreted as a first attempt to introduce the pilot‐wave theory in the context of quantum gravity and we infer that this was one of the reasons that ruled it out.

Besides his activities as a theoretical physicist, the Belgian Léon Rosenfeld cultivated and showed a lively concern for history of science since his student years. This paper is a study of his publications, correspondence and other endeavours in history of science, mainly during the early Cold War period, in order to explore his essentially Marxist views on science and society and how they differed from those of other Marxists scholars, most notably John D. Bernal and Boris Hessen.

In 1966 the Brazilian physicist Klaus Tausk (b. 1927) circulated a preprint from the International Centre for Theoretical Physics in Trieste, Italy, criticizing Adriana Daneri, Angelo Loinger, and Giovanni Maria Prosperi`s theory of 1962 on the measurement problem in quantum mechanics. A heated controversy ensued between two opposing camps within the orthodox interpretation of quantum theory, represented by Leon Rosenfeld and Eugene P. Wigner. The controversy went well beyond the strictly scientific issues, however, reflecting philosophical and political commitments within (...) the context of the Cold War, the relationship between science in developed and Third World countries, the importance of social skills, and personal idiosyncrasies.

The article examines the development of physics research in Ukraine on the example of the Ukrainian Institute of Physics and Technology (UIPT). Founded on the initiative of the eminent physicist Abram Ioffe, the UIPT has gradually become one of the world’s leading research institutions. During 1928–1938, many important events took place at the institute, which became markers for the development of physics in Ukraine and the USSR as well as in the world. An experiment on the fission of atomic nucleus (...) using artificially accelerated protons confirmed the validity of the intentions to reorient research towards nuclear physics. The involvement of foreign specialists in the work of the UIPT contributed to the informal consolidation of scientific thinking in physics. Outstanding physicists of the world such as Boris Podolskyi, Oleksandr Weisberg, Konrad Weiselberg, Friedrich Houtermans, Laszlo Tisza, Fritz Lange, Victor Weisskopf, George Placzek, Paul Dirac, Georgii Gamov, Niels Bohr, Paul Ehrenfest, and others worked here for longer or shorter periods. Niels Bohr, Ivar Waller, Milton S. Plesset, Evan J. Williams, and Leon Rosenfeld made reports at the theoretical conferences of UIPT. As a result, in the late 1920s and during the 1930s, an informal society of physicists from around the world was formed in Kharkiv. The consolidation of talented scientists has accumulated traditions, centuries of experience, and practical knowledge in the field from many scientific schools around the world. (shrink)

A posteriori physicalism is the combination of two appealing views: physicalism (i.e. the view that all facts are either physical or entailed by the physical), and conceptual dualism (i.e. the view that phenomenal truths are not entailed a priori by physical truths). Recently, some philosophers such as Goff (2011), Levine (2007) and Nida-Rümelin (2007), among others, have suggested that a posteriori physicalism cannot explain how phenomenal concepts can reveal the nature of phenomenal properties. In this paper, I wish to defend (...) a posteriori physicalism from this new and interesting challenge, by arguing that a posteriori physicalists have the resources to explain how phenomenal concepts can reveal at least something of what it would take for the corresponding phenomenal property to be instantiated. (shrink)

The inference from conceivability to possibility has been challenged in numerous ways. One of these ways is the so-called phenomenal concept strategy, which has become one of the main strategies against the conceivability argument against physicalism. However, David Chalmers has recently presented a dilemma for the phenomenal concept strategy, and he has argued that no version of the strategy can succeed. In this paper, I examine the dilemma, and I argue that there is a way out of it. I conclude (...) that Chalmers has not posed any serious problem for the phenomenal concept strategy to succeed in blocking the conceivability argument. In doing so, my aim is not only to show that Chalmers’s argument has not refuted the phenomenal concept strategy, but also to clarify what any version of the strategy should achieve in order to be successful. (shrink)

One of the main strategies against conceivability arguments is the so-called phenomenal concept strategy, which aims to explain the epistemic gap between physical and phenomenal truths in terms of the special features of phenomenal concepts. Daniel Stoljar has recently argued that the phenomenal concept strategy has failed to provide a successful explanation of this epistemic gap. In this paper my aim is to defend the phenomenal concept strategy from his criticisms. I argue that Stoljar has misrepresented the resources of the (...) strategy, which can indeed accomplish the required explanatory task, once it is properly understood. (shrink)

In this paper I examine Chalmers and Jackson’s defence of the a priori entailment thesis, that is, the claim that microphysical truths a priori entail ordinary non-phenomenal truths such as ‘water covers 60% of the Earth surface’, which they use as a premise for an argument against the possibility of a reductive explanation of consciousness. Their argument relies on a certain view about the possession conditions of macroscopic concepts such as WATER, known as ascriptivism. In the paper I distinguish two (...) versions of ascriptivism: reductive versus non-reductive ascriptivism. According to reductive ascriptivism, competent users of a concept have the ability to infer truths involving such concept from lower-level truths, whereas according to non-reductive ascriptivism, all that is required in order to be a competent user of a concept is to be able to infer truths involving that concept from other truths, which need not be lower-level truths. I argue, first, that the a priori entailment thesis is committed to reductive ascriptivism, and secondly, that reductive ascriptivism is problematic because it trivializes the notion of a priori knowledge. Therefore, I conclude that Chalmers and Jackson have not presented a convincing case for the claim that microphysical truths entail ordinary non-phenomenal truths a priori, especially when we understand this claim in the sense that is relevant for their argument against the possibility of a reductive explanation of consciousness. (shrink)

The hard problem of consciousness is about how we could explain in physicalist terms why we are conscious. The meta-problem of consciousness is about how we could explain why we have a hard problem of consciousness. In this note I argue that the phenomenal concept strategy can in principle provide a satisfactory solution to the meta-problem.

What does it mean to say that some features, such as gender, race and sexual orientation, are socially constructed? Many scholars claim that social constructionism about a kind is a version of realism about that kind, according to which the corresponding kind is a social construction, that it, it is constituted by social factors and practices. Social constructionism, then, is a version of realism about a kind that asserts that the kind is real, and puts forward a particular view about (...) the nature of the kind, namely, that it is constituted by social factors and practices. Social constructivists about human kinds such as gender, race and sexual orientation often make an additional claim, namely, that these kinds are social constructions but they are typically believed to be biological kinds (that is, people are typically wrong about the nature of these kinds). Ron Mallon (2017) calls social constructions that are (falsely) taken to be biological kinds covert social constructions. This paper is about how we could have terms in our natural language that come to refer to covert social constructions. (shrink)

There is some cost to you in voting. While it may be small for some, it is significant for others. Some people go to a great deal of effort just to vote. What return do they get for this effort? Zilch! A single vote can only impact an election when there is a tie, which has essentially zero chance of happening in a state or national election. The typical response to this is "Well, what if everyone did that?" Of course, (...) that would be a disaster. But we are not talking about everyone, we are talking about ONE individual. (shrink)

Are sexual orientations freely chosen? The idea that someone’s sexual orientation is not a choice is very influential in the mainstream LGBT political movement. But do we have good reasons to believe it is not a choice? Going against the orthodoxy, William Wilkerson has recently argued that sexual orientation is partly constituted by our interpretations of our own sexual desires, and we choose these interpretations, so sexual orientation is partly constituted by choice. In this paper I aim to examine the (...) question of whether our interpretations of our own sexual desires are constitutive of our sexual orientations. I will argue that whereas Wilkerson’s argument for the claim that sexual orientations are in part constituted by our chosen interpretations of our sexual desires is not sound, there are good reasons for endorsing a weaker claim, namely, that there are different but equally apt descriptions of the same sexual desires, depending on which concepts we have.

The so-called “disquotational theory of truth” has not previously been developed much beyond the thesis that saying, for example, that ‘Snow is white’ is true amounts only to saying that snow is white. Marian David has set out to see what further sense can be made of the disquotational theory, and to compare its merits with those of correspondence theories of truth. His prognosis is that an intelligible disquotational theory of truth can be developed but will suffer from drastic shortcomings (...) that make it all but unusable. (shrink)

It is said that society is in a moral crisis. And, what is worse, it seems to be deteriorating at an ever increasing rate. We all agree that something needs to be done.

We are witnessing some incredibly baffling problems in the world today. It seems that as the countries of the world become more "civilized", more "democratic", societal problems and conflicts just get worse. The theme of this essay is that many of these problems are a result of an inherent and unavoidable paradox involving the conflict between the needs of the individual and the needs of the society that the individual is a member of. This class of problem, often called "Social (...) Dilemmas", while not unknown in the academic community has received little public attention. Yet these dilemmas may present insurmountable barriers to a peaceful world and harmonious societies. (shrink)

What I would like to say about politics does not fit the mold of common discourse and most political essays. Frankly, I have a rather negative and skeptical view of the concept that a group of people somehow has the knowledge to know what is best and the right to impose their will on the rest of the population. In fact, I think it is mankind's greatest folly to think that we can pick out a group of people from the (...) population at large -- known to be selfish, brutish and not necessarily very honest -- and to believe that these selected individuals will some how rise above the level from which they came, and to believe in these selected individuals so strongly that we will even give them guns and a monopoly over force!

There is a very simple reason why people act the way they do and it is given by the following maxim: Maxim #1: Individuals tend to do the things they are rewarded for doing and tend to avoid the things they are punished for doing. Before you discard this simple maxim as being too simple to be of any use, let me explain just a bit. For a given situation, this maxim puts you one step closer and in the right (...) direction to understanding why people behave as they do. Let us try it on a simple example: Why do government employees waste money? If you want to know the answer to this then see if you can determine how government employees are rewarded and punished.

The "Prisoner's Dilemma" game has been extensively discussed in both the public and academic press. Thousands of articles and many books have been written about this disturbing game and its apparent representation of many problems of society. The origin of the game is attributed to Merrill Flood and Melvin Dresher. I quote from the Stanford Encyclopedia of Philosophy: Puzzles with this structure were devised and discussed by Merrill Flood and Melvin Dresher in 1950, as part of the Rand CorporationÂ’s investigations (...) into game theory (which Rand pursued because of possible applications to global nuclear strategy). The title "prisonerÂ’s dilemma" and the version with prison sentences as payoffs are due to Albert Tucker, who wanted to make Flood and DresherÂ’s ideas more accessible to an audience of Stanford psychologists. The Prisoner's Dilemma is a short parable about two prisoners who are individually offered a chance to rat on each other for which the "ratter" would receive a lighter sentence and the "rattee" would receive a harsher sentence. The problem results from the fact that both can play this game -- that is, defect -- and if both do, then both do worse than they would had they both kept silent. This peculiar parable serves as a model of cooperation between two or more individuals (or corporations or countries) in ordinary life in that in many cases each individual would be personally better off not cooperating (defecting) on the other.

The most puzzling aspect of Social Choice theory[1] is that people cooperate much more than the theory suggests. There are several reasons why this is so, including the fact that people are not always rational -- particularly by the definition of "rational" used by the Social Choice theorists! Another obvious reason is that people act out of ignorance much of the time.

Some people voluntarily provide public goods while others take a free ride. Are the providers acting rationally? Should they instead follow the example of the free-rider? What are the rational and moral justifications for voluntary provision? This dissertation examines five ways to justify voluntary provision: rational prudence, social norms, group agency, fairness, and altruism. It suggests that altruism provides the best possible defense. Considerations of fairness may also provide a justification in some circumstances, but generally this argument is vulnerable to (...) the objection that free-riding is often a legitimate way of protecting oneself from exploitation by other free-riders. In places, the dissertation relies on simple game theoretic models and intuitive economic equilibrium notions to analyze public good situations. The dissertation closes with a discussion of the government's role in providing public goods. An argument is made that, for certain kinds of goods (those over which preferences are public, but whose benefits are private), the standard public goods argument is not appropriate to homogeneous populations. If this is correct, other justifications for governmental provision must be summoned for goods of this form. (shrink)
