Towards the end of eighteenth century in France, the newly acquired rights of people as citizens needed assuring. This article traces the principles through which Condorcet tried to realise this on an institutional level. Condorcet did not view the Enlightenment ideas of progress as primarily referring to the state. Rather, he focused on the rights of individuals, particularly on their right to develop their own potential. He bound this perception with the unconditional demand for recognition of the rights of all (...) people, in particular also for a clear renunciation of any gender-specific interpretation of this fundamental idea. Evidence for this is found in Condorcet’s writings on Instruction Publique. In contrast to other educational programmes of the revolutionary period, these evince a discriminating interpretation of freedom and equality, and recognise the numerous threats to a self-determined human existence.

It is shown that, given any finite set of pairs of random events in a Boolean algebra which are correlated with respect to a fixed probability measure on the algebra, the algebra can be extended in such a way that the extension contains events that can be regarded as common causes of the correlations in the sense of Reichenbach's definition of common cause. It is shown, further, that, given any quantum probability space and any set of commuting events in it (...) which are correlated with respect to a fixed quantum state, the quantum probability space can be extended in such a way that the extension contains common causes of all the selected correlations, where common cause is again taken in the sense of Reichenbach's definition. It is argued that these results very strongly restrict the possible ways of disproving Reichenbach's Common Cause Principle. (shrink)

A partition $\{C_i\}_{i\in I}$ of a Boolean algebra $\cS$ in a probability measure space $(\cS,p)$ is called a Reichenbachian common cause system for the correlated pair $A,B$ of events in $\cS$ if any two elements in the partition behave like a Reichenbachian common cause and its complement, the cardinality of the index set $I$ is called the size of the common cause system. It is shown that given any correlation in $(\cS,p)$, and given any finite size $n>2$, the probability space (...) $(\cS,p)$ can be embedded into a larger probability space in such a manner that the larger space contains a Reichenbachian common cause system of size $n$ for the correlation. It also is shown that every totally ordered subset in the partially ordered set of all partitions of \cS$ contains only one Reichenbachian common cause system. Some open problems concerning Reichenbachian common cause systems are formulated. (shrink)

Standard derivations of the Bell inequalities assume a common-commoncause-system that is a common screener-off for all correlations and some additional assumptions concerning locality and no-conspiracy. In a recent paper Graßhoff et al., "The British Journal for the Philosophy of Science", 56, 663–680 ) Bell inequalities have been derived via separate common causes assuming perfect correlations between the events. In the paper it will be shown that the assumptions of this separate-common-cause-type derivation of the Bell inequalities in the case of perfect (...) correlations can be reduced to the assumptions of a common-common-cause-system-type derivation. However, in the case of non-perfect correlations a non-reducible separate-common-cause-type derivation of some Bell-like inequalities can be given. The violation of these Bell-like inequalities proves Szabo's ) conjecture concerning the non-existence of a local, non-conspiratorial, separate-common-cause-model for a δ-neighborhood of perfect EPR correlations.

A partition $\{C_i\}_{i\in I}$ of a Boolean algebra Ω in a probability measure space (Ω, p) is called a Reichenbachian common cause system for the correlation between a pair A,B of events in Ω if any two elements in the partition behave like a Reichenbachian common cause and its complement; the cardinality of the index set I is called the size of the common cause system. It is shown that given any non-strict correlation in (Ω, p), and given any finite (...) natural number n > 2, the probability space (Ω,p) can be embedded into a larger probability space in such a manner that the larger space contains a Reichenbachian common cause system of size n for the correlation.

A condition is formulated in terms of the probabilities of two pairs of correlated events in a classical probability space which is necessary for the two correlations to have a single (Reichenbachian) common-cause and it is shown that there exists pairs of correlated events probabilities of which violate the necessary condition. It is concluded that different correlations do not in general have a common common-cause. It is also shown that this conclusion remains valid even if one weakens slightly Reichenbach's definition (...) of common-cause. The significance of the difference between common-causes and common common-causes is emphasized from the perspective of Reichenbach's Common Cause Principle. (shrink)

This essay has two main claims about EPR’s Reality Criterion. First, we claim that the application of the Reality Criterion makes an essential difference between the EPR argument and Einstein’s later arguments against quantum mechanics. We show that while the EPR argument, making use of the Reality Criterion, does derive that certain interpretations of quantum mechanics are incomplete, Einstein’s later arguments, making no use of the Reality Criterion, do not prove incompleteness, but rather point to the inadequacy of the Copenhagen (...) interpretation. We take this fact as an indication that the Reality Criterion is a crucial, indispensable component of the incompleteness argument(s). The second claim is more substantive. We argue that the Reality Criterion is a special case of the Common Cause Principle. Finally, we relate this proposal to Tim Maudlin’s recent assertion that the Reality Criterion is an analytic truth. (shrink)

In a recent paper, Cabbolet argues that the PBR theorem is nonreal since in the ensemble interpretation of quantum mechanics the entangled measurement used in the derivation of the PBR theorem is nonexisting. However, Cabbolet (1) does not provide any argument for the nonexistence of entangled measurements beyond the incompatibility of the existence of entangled measurements and the existence of $$\psi$$ -epistemic models which we already know from the PBR theorem; and (2) he does not show why it is more (...) reasonable to abandon entangled measurements instead of $$\psi$$ -epistemic models. Hence, the PBR theorem remains intact. (shrink)

In the paper it will be shown that Reichenbach’s Weak Common Cause Principle is not valid in algebraic quantum field theory with locally finite degrees of freedom in general. Namely, for any pair of projections A, B supported in spacelike separated double cones ${\mathcal{O}}_{a}$ and ${\mathcal{O}}_{b}$ , respectively, a correlating state can be given for which there is no nontrivial common cause (system) located in the union of the backward light cones of ${\mathcal{O}}_{a}$ and ${\mathcal{O}}_{b}$ and commuting with the both (...) A and B. Since noncommuting common cause solutions are presented in these states the abandonment of commutativity can modulate this result: noncommutative Common Cause Principles might survive in these models.

It is shown that, given any finite set of pairs of random events in a Boolean algebra which are correlated with respect to a fixed probability measure on the algebra, the algebra can be extended in such a way that the extension contains events that can be regarded as common causes of the correlations in the sense of Reichenbach's definition of common cause. It is shown, further, that, given any quantum probability space and any set of commuting events in it (...) which are correlated with respect to a fixed quantum state, the quantum probability space can be extended in such a way that the extension contains common causes of all the selected correlations, where common cause is again taken in the sense of Reichenbachs definition. It is argued that these results very strongly restrict the possible ways of disproving Reichenbach's Common Cause Principle. (shrink)

Bell inequalities, understood as constraints between classical conditional probabilities, can be derived from a set of assumptions representing a common causal explanation of classical correlations. A similar derivation, however, is not known for Bell inequalities in algebraic quantum field theories establishing constraints for the expectation of specific linear combinations of projections in a quantum state. In the paper we address the question as to whether a ‘common causal justification’ of these non-classical Bell inequalities is possible. We will show that although (...) the classical notion of common causal explanation can readily be generalized for the non-classical case, the Bell inequalities used in quantum theories cannot be derived from these non-classical common causes. Just the opposite is true: for a set of correlations there can be given a non-classical common causal explanation even if they violate the Bell inequalities. This shows that the range of common causal explanations in the non-classical case is wider than that restricted by the Bell inequalities. (shrink)

I will argue that Kochen-Specker arguments do not provide an algebraic proof for quantum contextuality since, for the argument to be effective, operators must be uniquely associated with measur...

I will argue that the Peres-Mermin square does not necessarily rule out a value-definite (deterministic) noncontextual hidden variable model if the operators are not given a physical interpretation satisfying the following two requirements: (i) each operator is uniquely realized by a single physical measurement; (ii) commuting operators are realized by simultaneous measurements. To underpin this claim, I will construct three hidden variable models for three different physical realizations of the Peres-Mermin square: one violating (i), another violating (ii), and a third (...) one violating both (i) and (ii).

The aim of this paper is to give a sharp definition of Bell's notion of local causality. To this end, first we unfold a framework, called local physical theory, integrating probabilistic and spatiotemporal concepts. Formulating local causality within this framework and classifying local physical theories by whether they obey local primitive causality---a property rendering the dynamics of the theory causal, we then investigate what is needed for a local physical theory, with or without local primitive causality, to be locally causal. (...) Finally, comparing Bell's local causality with the Common Cause Principles and relating both to the Bell inequalities we find a nice parallelism: Bell inequalities cannot be derived neither from local causality nor from a common cause unless the local physical theory is classical or the common cause is commuting, respectively.

This paper is the philosopher-friendly version of our more technical work. It aims to give a clear-cut definition of Bell's notion of local causality. Having provided a framework, called local physical theory, which integrates probabilistic and spatiotemporal concepts, we formulate the notion of local causality and relate it to other locality and causality concepts. Then we compare Bell's local causality with Reichenbach's Common Cause Principle and relate both to the Bell inequalities. We find a nice parallelism: both local causality and (...) the Common Cause Principle are more general notions than captured by the Bell inequalities. Namely, Bell inequalities cannot be derived neither from local causality nor from a common cause unless the local physical theory is classical or the common cause is commuting, respectively.

ZusammenfassungDer Internistenkongress von 1949 war Anlass und Arena einer breit wahrgenommenen Kontroverse zu epistemologischen Fragen der Psychosomatischen Medizin. Der Beitrag verortet zunächst den Kongress in der Nachkriegsgeschichte und zeichnet die Verlaufslinien der Debatte nach. Dabei werden sowohl die Positionen der Sprecher der Psychosomatischen Medizin – Viktor von Weizsäcker und Alexander Mitscherlich – als auch diejenige von Paul Martini, der auf Basis seiner Methodologie klinischer Forschung grundsätzliche Kritik äußerte, rekonstruiert. In einem zweiten Schritt werden die jeweils unterschiedlichen Auffassungen von Kausalität, Evidenz (...) und Subjektivität herausgearbeitet und kontextualisiert. Das Hauptaugenmerk liegt hierbei auf dem konkreten und expliziten Gebrauch dieser Begriffe bei Martini. Schließlich zeige ich, dass diese Ereignisse im Jahr 1949 als Kulmination einer fortdauernden Kontroverse über wissenschaftliche Evidenz in der klinischen Medizin gelesen werden können, die sich mit ihren Beteiligten und Bezugsebenen über mehrere Jahrzehnte erstreckte.

It is a well known fact that a common common causal explanation of the EPR scenario which consists in providing a local, non-conspiratorial common common cause system for a set of EPR correlations is excluded by various Bell inequalities. But what if we replace the assumption of a common common cause system by the requirement that each correlation of the set has a local, non-conspiratorial separate common cause system? In the paper we show that this move does not yield a (...) solution by providing a general recipe how to derive any Bell(δ) inequality—that is an inequality differing from some Bell inequality in a term of order of δ—from the assumption that an appropriate set of almost perfect anticorrelations has a separate common causal explanation.

Nineteen newly-transliterated letters between Ferdinand Christian Baur and his friend Ludwig Friedrich Heyd are presented. Seventeen of them were written by Baur, and two by Heyd in the period between 10th February 1836 and 16th January 1842. A further sixteen earlier letters were already published by Carl Egbert Hester in 1993. The correspondence between the two close friends cover a broad range of subjects, predominantly historical, as well as family, scientific, political themes and particularly university politics. The key personal topic (...) is the death of Baur’s wife in 1839 and the consequences of this for their children. The scientific themes concern firstly Baur’s efforts to assist Heyd in his research into the history of Württemberg, and to promote these works to publishers. Secondly, the letters document the reaction of the two to David Friedrich Strauß’s work “Das Leben Jesu”, and how their views changed during this correspondence. The central political themes of the letters relate primarily to appointments within Tübingen University, and in particular to previously unknown attacks on Baur’s own position there. Further discussions concern two politically arranged festivals; the Buchhändlerfest of 1840, and the 25th coronation anniversary of King Wilhelm I. of Württemberg in 1841, at which Baur gave a courageous speech on the political situation in Württemberg. Of particular interest in the letters previously transliterated by Hester are two topics, firstly the “Polish Petition” regarding the political situation in Poland in the 1830s, and secondly regarding the constitution of Tübingen University. To better understand the significance of these private letters and their openness, a short biography of Heyd is included. (shrink)

It will be shown that the Peres–Mermin square admits value-definite noncontextual hidden-variable models if the observables associated with the operators can be measured only sequentially but not simultaneously. Namely, sequential measurements allow for noncontextual models in which hidden states update between consecutive measurements. Two recent experiments realizing the Peres–Mermin square by sequential measurements will also be analyzed along with other hidden-variable models accounting for these experiments.

Neoliberalism has come to be understood not only as an economic system, but as a mode of existence that understands the self as primarily the bearer of human capital. This paper contrasts the neoliberal ideal of selfhood with Kierkegaard’s notion of the self as developed in The Sickness unto Death. Using Kierkegaard’s typology of despair as an analytical framework, I argue that the neoliberal subject displays an impoverished grasp of the various elements that, for Kierkegaard, are constitutive of the self, (...) and shows serious deficiencies in its understanding of what it means to live a meaningful life.

The aim of the paper is to relate Bell’s notion of local causality to the Causal Markov Condition. To this end, first a framework, called local physical theory, will be introduced integrating spatiotemporal and probabilistic entities and the notions of local causality and Markovity will be defined. Then, illustrated in a simple stochastic model, it will be shown how a discrete local physical theory transforms into a Bayesian network and how the Causal Markov Condition arises as a special case of (...) Bell’s local causality and Markovity. (shrink)

In the paper the relation between the standard probabilistic characterization of the common cause and Bell's notion of local causality will be investigated. It will be shown that the probabilistic common cause follows from local causality if one accepts, as Bell did, two assumptions concerning the common cause: first, the common cause is localized in the intersection of the past of the correlating events; second, it provides a complete specification of the `beables' of this intersection. However, neither assumptions are a (...) priori requirements. In the paper the logical role of these assumptions will be studied and it will be shown that only the second assumption is necessary for the derivation of the probabilistic common cause from local causality.

The structuralist approach, as developed by Balzer et al. (1987) in An Architectonic for Science (abbreviated as Architectonic in the following), should be combined with a holistic semantics. A significant, but widely neglected intuition about the empirical claim of a theory appears to be representable only within a holistic framework. This intuition may be called the promise of a theory. It consists of the claim that the theory will, at least in the future, be able to describe all phenomena of (...) (an interpreted version of) its T-non-theoretical conceptual frame. The argument will be outlined within the semantics developed by Holger Andreas on the basis of Carnap’s dual-level conception. (shrink)

This paper aims to implement Bell’s notion of local causality into a framework, called local physical theory, which is general enough to integrate both probabilistic and spatiotemporal concepts and also classical and quantum theories. Bell’s original idea of local causality will then arise as the classical case of our definition. First, we investigate what is needed for a local physical theory to be locally causal. Then we compare local causality with Reichenbach’s common cause principle and relate both to the Bell (...) inequalities. We find a nice parallelism: both local causality and the common cause principle are more general notions than captured by the Bell inequalities. Namely, Bell inequalities cannot be derived neither from local causality nor from a common cause unless the local physical theory is classical or the common cause is commuting, respectively.

Epistemic Encounters, Emerging Challenges. Three Thoughts about the History of Science and Medicine. With good reason, the future of the history of science and medicine can be characterized as a continuous move towards diversity. Epistemic encounters between disciplines, approaches and subject areas are continuously emerging. At the same time, new and disturbing challenges have arisen in the relationship between science, politics and society. Based on this observation, the following miniature offers three reflective thoughts. These aim (1) to raise more awareness (...) of the socio‐political responsibility of historiographical positioning; (2) to address questions of (historical) relationality and (theoretical) systematicity more explicitly; and (3), and by focusing on German academic medicine, to highlight some desiderata at the intersection of the history of science and contemporary history.

This book collects research papers on the philosophical foundations of probability, causality, spacetime and quantum theory. The papers are related to talks presented in six subsequent workshops organized by The Budapest-Kraków Research Group on Probability, Causality and Determinism. Coverage consists of three parts. Part I focuses on the notion of probability from a general philosophical and formal epistemological perspective. Part II applies probabilistic considerations to address causal questions in the foundations of quantum mechanics. Part III investigates the question of indeterminism (...) in spacetime theories. It also explores some related questions, such as decidability and observation. The contributing authors are all philosophers of science with a strong background in mathematics or physics. They believe that paying attention to the finer formal details often helps avoiding pitfalls that exacerbate the philosophical problems that are in the center of focus of contemporary research. The papers presented here help make explicit the mathematical-structural assumptions that underlie key philosophical argumentations. This formally rigorous and conceptually precise approach will appeal to researchers and philosophers as well as mathematicians and statisticians. (shrink)

New York may be most easily recognized by its trademark skyscrapers and brick tenement buildings, but the truth is that the city is actually teeming with luxurious roof gardens and private courtyard oases. Creative gardeners and architects have risen to meet the unique challenges of the urban landscape, designing spaces that celebrate the city while providing a restful escape. New York City Gardens presents New York’s evolving tradition of garden culture through images and discussions of thirty of its most outstanding (...) gardens, from world-famous botanical gardens to richly re-cultivated public urban spaces, luxurious penthouse terraces, and innovative art gardens without soil or plants. Many of the gardens are set against vistas of the quintessential New York—Central Park, the Empire State Building, skyscrapers of Midtown, and the sensational skyline of Lower Manhattan. Other gardens reveal surprising and exotic intimate retreats from the bustle of the city. While most were designed by noted landscape architects, including Dan Kiley, Hideo Sasaki, Ken Smith, and Halsted Wells, many others were created over decades by talented homeowners themselves. As more and more city dwellers in New York and beyond look to cultivate their own kitchen and container gardens and individual outdoor sanctuaries, this book provides hundreds of inspiring images as well as historical background and insight into the practical and imaginative solutions of city garden designers.
