The Great Divide in metaphysical debates about laws of nature is between Humeans, who think that laws merely describe the distribution of matter, and non-Humeans, who think that laws govern it. The metaphysics can place demands on the proper formulations of physical theories. It is sometimes assumed that the governing view requires a fundamental / intrinsic direction of time: to govern, laws must be dynamical, producing later states of the world from earlier ones, in accord with the fundamental direction of (...) time in the universe. In this paper, we propose a minimal primitivism about laws of nature (MinP) according to which there is no such requirement. On our view, laws govern by constraining the physical possibilities. Our view captures the essence of the governing view without taking on extraneous commitments about the direction of time or dynamic production. Moreover, as a version of primitivism, our view requires no reduction / analysis of laws in terms of universals, powers, or dispositions. Our view accommodates several potential candidates for fundamental laws, including the principle of least action, the Past Hypothesis, the Einstein equation of general relativity, and even controversial examples found in the Wheeler-Feynman theory of electrodynamics and retrocausal theories of quantum mechanics. By understanding governing as constraining, non-Humeans who accept MinP have the same freedom to contemplate a wide variety of candidate fundamental laws as Humeans do. (shrink)

The wave function in quantum mechanics presents an interesting challenge to our understanding of the physical world. In this paper, I show that the wave function can be understood as four intrinsic relations on physical space. My account has three desirable features that the standard account lacks: it does not refer to any abstract mathematical objects, it is free from the usual arbitrary conventions, and it explains why the wave function has its gauge degrees of freedom, something that are usually (...) put into the theory by hand. Hence, this account has implications for debates in philosophy of mathematics and philosophy of science. First, by removing references to mathematical objects, it provides a framework for nominalizing quantum mechanics. Second, by excising superfluous structure such as overall phase, it reveals the intrinsic structure postulated by quantum mechanics. Moreover, it also removes a major obstacle to ``wave function realism.''. (shrink)

A strongly deterministic theory of physics is one that permits exactly one possible history of the universe. In the words of Penrose (1989), "it is not just a matter of the future being determined by the past; the entire history of the universe is fixed, according to some precise mathematical scheme, for all time.” Such an extraordinary feature may appear unattainable in a world like ours. In this paper, I show that it can be achieved in a simple way and (...) discuss its implications for metaphysics and philosophy of science, including natural properties, free will, explanation, and modality. First, I propose a precise definition of strong determinism. Next, I discuss its philosophical ramifications and a toy example. Finally, I provide a realistic example of a strongly deterministic (and simple) physical theory---the Everettian Wentaculus. A surprising consequence is that whether or not our world is strongly deterministic may be empirically underdetermined. (shrink)

Two of the most difficult problems in the foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. They are difficult because the fundamental dynamical laws of physics do not privilege an arrow of time, and the quantum-mechanical wave function describes a high-dimensional reality that is radically different from our ordinary experiences. -/- In this paper, I characterize and elaborate on the ``Wentaculus” theory, a new approach to time’s (...) arrow in a quantum universe that offers a unified solution to both problems. Central to the Wentaculus are (i) Density Matrix Realism, the idea that the quantum state of the universe is objective but can be impure, and (ii) the Initial Projection Hypothesis, a new law of nature that selects a unique initial quantum state. On the Wentaculus, the quantum state of the universe is sufficiently simple to be a law, and the arrow of time can be traced back to an exact boundary condition. It removes the intrinsic vagueness of the Past Hypothesis, eliminates the Statistical Postulate, provides a higher degree of theoretical unity, and contains a natural realization of “strong determinism." I end by responding to four recent objections. In a companion paper, I elaborate on Density Matrix Realism. (shrink)

Developmentally, adolescence sits in transition between childhood and adulthood. Involving adolescents in their medical decision-making prompts important and complex ethical questions. Originating in the UK, the concept of Gillick competence is a dominant framework for navigating adolescent medical decision-making from legal, ethical and clinical perspectives and is commonly treated as comprehensive. In this paper, we argue that its utility is far more limited, and hence over-reliance on Gillick risks undermining rather than promoting ethically appropriate adolescent involvement. We demonstrate that Gillick (...) only provides guidance in the limited range of cases where legal decisional authority needs to be clarified. The range of cases where use of Gillick actually promotes adolescent involvement is narrower still, because several features must be present for Gillick to be enacted. Each of these features can, and do, act as barriers to adolescent involvement. Within these limited situations, we argue that Gillick is not specific or strong enough and is reliant on ethically contestable principles. Moreover, in most situations in adolescent healthcare, Gillick is silent on the ethical questions around involving adolescents. This is because it focuses on decisional authority—having the final say in decision-making—which is one small subset of the many ways adolescents could be involved in decision-making. The implication of our analysis is that use of Gillick competence tends to limit or undermine adolescent involvement opportunities. We propose that those working with adolescents should be judicious in seeking Gillick’s guidance, instead drawing on and developing alternative frameworks that provide a comprehensive model for adolescent involvement.

The “Assyrian Century,” the period of Assyrian rule in the Levant, is usually regarded as an era of prosperity and economic progress. As far as the southern Levant is concerned, this reconstruction more or less reflects the reality on the southern edge of the region—in the areas of Philistia, Judah, and Edom. But what was the situation in the northern part of the country, in the territories of the former kingdom of Israel and adjacent territories, regions that had become Assyrian (...) provinces? It is the aim of this paper to scrutinize the archaeological data from these regions in order to shed light on the settlement and demographic reality in those provinces, and furthermore to reassess Assyrian policy in the west. After summarizing previous research, the article will present the available archaeological data, which will then be compared with that from the southern part of the country in order to enable a reexamination of the Assyrian empire’s policy in the west.

An engaging and inspiring set of reflections by one of the master educators of today's Jewish world - full of delightful stories, compelling analysis and generosity of spirit. Read it and your faith in the Jewish future will be renewed. - Rabbi Lord Jonathan Sacks.

Adam and Eve have the same record yet receive different punishments. Adam receives the punishment that they both deserve, whereas Eve receives a more lenient punishment. In this article, we explore whether a deserved-but-unequal punishment, such as what Adam receives, can be just. We do this by explicating the conceptions of retributive justice that underlie both sides of the debate. We argue that inequality in punishment is disturbing mainly because of the disrespect it often expresses towards the offender receiving the (...) harsher treatment, and also because it casts doubt on whether Adam got what he deserved. We suggest that when no disrespect is involved and when it is clear that the criminal got what he deserved, inequality is not worrisome. (shrink)

The class of stable posets is defined and investigated. We give a forcing construction of a universe of set theory which satisfies a weak form of Martin's Axiom and $2^{\aleph_0} > \aleph_1$ and yet some propositions which follow from CH hold in this universe.

Traumatic brain injury is a major cause of death and disability in Western society, and often results in functional and neuropsychological abnormalities. Memory impairment is one of the most significant cognitive implications after TBI. In the current study we investigated procedural memory acquisition by observational training in TBI patients. It was previously found that while practicing a new motor skill, patients engage in all three phases of skill learning–fast acquisition, between-session consolidation, and long-term retention, though their pattern of learning is (...) atypical compared to healthy participants. A different set of studies showed that training by observing a motor task, generally prompted effective acquisition and consolidation of procedural knowledge in healthy participants. The aim of our study was to evaluate the potential benefit of action observation in TBI patients. Examine the possibility of general improvement in performance between the first and second stage of the study. Investigate the link between patients’ ability to benefit from observational learning and common measures of injury.Materials and methodsPatients hospitalized after moderate to severe TBI, were trained by observation for the finger opposition sequence motor task. They were then tested for the observation-trained sequence and a similar control sequence, at two different time-points.Results revealed a significant difference in performance between the trained and untrained sequences, in favor of the trained sequence. An increase in performance for both sequences A and B toward the second session. The advantage for sequence A was stable and preserved also in the second session. Participants with lower moderate Functional Independence Measure scores gained more from observational-procedural learning, compared with patients with higher functional abilities.ConclusionOverall, these findings support the notion that TBI patients may achieve procedural memory consolidation and retention through observational learning. Moreover, different functional traits may predict the outcomes of observational training in different patients. These findings may have significant practical implications in the future, regarding skill acquisition methods in TBI patients. (shrink)

This paper questions the fairness of our current tort-law regime and the philosophical underpinnings advanced in its defense, a theory known as corrective justice. Fairness requires that the moral equality and responsibility of persons be respected in social interactions and institutions. The concept of luck has been used by many egalitarians as a way of giving content to fairness by differentiating between those benefits and burdens that result from informed choice and those that result from fate or fortune. We argue (...) that the theory of corrective justice, along with its institutional embodiment of tort law, is at odds with an egalitarian commitment to fairness because it allows luck an unjustifiable role in determining dissimilar liability for similar wrongs and dissimilar compensation for similar losses to bodily integrity. Many egalitarian political theorists have also recognized, if not defended, the notion of distinct forms of justice, namely corrective, retributive, and distributive. Although theorists of these different forms of justice have been concerned with negating unfair luck inside the operations of each form of justice, there has been little attention to the way in which luck operates to sort cases into each form of justice. We claim that there is a significant way in which luck operates to subject different people to principles of corrective, retributive, and distributive justicewhich flies in the face of the egalitarian value of fairness. After surveying the arguments put forward by theorists defending a categorical distinction between corrective justice and retributive and distributive principles, we argue that although analytical distinctions can be made between different forms of justice (although, we also suggest that the distinctions are not as sharp as some commentators suggest), there is no good reason to defend an acoustic separation between these forms of justice when doing so creates unfair outcomes.

The movement known as Deutsche Physik (German physics) evolved hand in hand with National Socialism. It represented a marginal but vocal group of German scientists and science scholars who profiled themselves as defenders of “Aryan” science and called for the elimination of the “Jewish spirit” that they saw as epitomized by Albert Einstein’s relativity theory and as dominating the natural sciences, even in Nazi Germany. This infamous movement is most associated with the Nobel laureate physicists Philipp Lenard and Johannes Stark, (...) who founded it and gave it its initial political impetus during the early years of the Third Reich. However, in its main and final phase, between 1937 and 1943, the movement was no longer led by Lenard and Stark but by the philosopher of science Hugo Dingler (1881–1954) and his Munich-based circle. Tracing the development of his career until 1937, this article examines how Dingler came to play this role both despite and because of the significant differences between his and the better known Lenard-Stark strand of Deutsche Physik. Special attention is paid to Dingler’s subversive use of theoretical principles—particularly his framing of his work as a radical search for certainty—to advance the movement’s antiscientific agenda.

This study examines the relation between firms' corporate philanthropic giving and their performance in three other social domains - employee relations, environmental issues, and product safety. Based on a sample of 384 U.S. companies and using data pooled from 1998 through 2000, we find that worse performers in the other social areas are both more likely to make charitable contributions and that the extent of their giving is larger than for better performers. Analyses of each separate area of social performance, (...) however, indicate that the relation between giving and negative social performance only holds for the environmental issues and product safety areas. We find no significant association between corporate philanthropy and employee relations concerns. In general, these findings suggest that corporate philanthropy may be more a tool of legitimization than a measure of corporate social responsibility. (shrink)

Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments (...) about different and unrelated visual stimulus properties. We found that inter-individual differences were strongly correlated between the two tasks for metacognitive ability but not objective performance. Such stability of an individual’s metacognitive ability across different perceptual tasks indicates a general mechanism supporting metacognition independent of the specific task. (shrink)
