Einstein regarded as one of the triumphs of his 1915 theory of gravity - the general theory of relativity - that it vindicated the action-reaction principle, while Newtonian mechanics as well as his 1905 special theory of relativity supposedly violated it. In this paper we examine why Einstein came to emphasise this position several years after the development of general relativity. Several key considerations are relevant to the story: the connection Einstein originally saw between Mach's analysis of (...) inertia and both the equivalence principle and the principle of general covariance, the waning of Mach's influence owing to de Sitter's 1917 results, and Einstein's detailed correspondence with Moritz Schlick in 1920.

The Galilei invariance of classical dynamics does not automatically imply the third Newtonian axiom and the center of mass theorem. For the deduction of these theorems from Galilei invariance we must have, generally, a “kinematical potential” (Helmholtz) and a “potential function” (Clausius), respectively. In celestial mechanics it is possible to have conservation of the motion of the center of gravity but not of the mass center. In this case, the active and the passive masses are different quantities.

Reaction is a subject usually avoided by political theorists, since it raises awkward historical, philosophical and political questions. Perhaps philosophers of history might make better sense of it. In this article I claim that reaction has to be understood in relation to the concepts of revolution, tradition, progress and conservatism. I argue that the specific meaning of reaction is a response to the specific action that establishes the principle that order should be established only on (...) enlightened principles. The few theorists who have dealt with reaction have disagreed about whether it is the same as conservatism or not. I show that reaction is not an element in what I call a status quo conservatism, though it is an element in any conservatism conceived more broadly. I characterise reaction in full as the attempt to reverse the establishment of the principle that only enlightened principles shall be the basis of political order, the attempt to resist the further establishment of those enlightened principles, and also the attempt to criticise contemporary enlightened politics in terms of the unenlightened standards which existed before the revolution.

COVID-19 is compromising all aspects of society, with devastating impacts on health, political, social, economic and educational spheres. A premium is being placed on scientific research as the source of possible solutions, with a situational imperative to carry out investigations at an accelerated rate. There is a major challenge not to neglect ethical standards, in a context where doing so may mean the difference between life and death. In this paper we offer a rubric for considering the ethical challenges in (...) COVID-19 related research, in the form of an ethics toolkit for global research developed at the University of Edinburgh in collaboration with more than 200 global researchers from around the world. This toolkit provides a framework to support confrontation of ethical conflicts through the integrated and iterative analysis of Place, People, Principles and Precedents, throughout the research journey. Two case analyses are offered to exemplify the utility of the toolkit as a flexible and dynamic tool to promote ethical research in the context of COVID-19. (shrink)

This article presents a simple derivation of optimization models for reaction networks leading to a generalized form of the mass-action law, and compares the formal structure of Minimum Information Divergence, Quadratic Programming and Kirchhoff type network models. These optimization models are used in related articles to develop and illustrate the operation of ontology alignment algorithms and to discuss closely connected issues concerning the epistemological and statistical significance of sharp or precise hypotheses in empirical science.

Intuitively, we judge that our responsibility has more to do with what we do than what we omit to do, and that it extends more to intended effects than to side-effects of our deeds. These intuitions have been expressed in our tradition through two principles: the doctrine of acts and omissions and the doctrine of double effect. Jonathan Glover acknowledges that these two principles are important, but believes that it is eventually better to discard them and, instead, to stick to (...) the consequentialist view that our responsibility extends equally to all the consequences of our behavior. I first examine Glover’s objections against the two principles and then present Joshua Greene’s research on the neuropsychology of moral judgment. These rest heavily on our reactions to certain moral dilemmas, in particular the trolley problem, and have recourse to neuroimaging. Greene’s conclusions go in the same direction as Glover’s more conceptual arguments. However, both authors share a common philosophical view, i.e., consequentialism. Thus, in a last section I consider some difficulties that this moral view encounters, and with the aid of other neuropsychological studies, I conclude that it is not judicious to put aside the intentions of an agent.

The action-reaction principle (AR) is examined in three contexts: (1) the inertial-gravitational interaction between a particle and space-time geometry, (2) protective observation of an extended wave function of a single particle, and (3) the causal-stochastic or Bohm interpretation of quantum mechanics. A new criterion of reality is formulated using the AR principle. This criterion implies that the wave function of a single particle is real and justifies in the Bohm interpretation the dual ontology of the particle (...) and its associated wave function. But it is concluded that the Bohm theory is not dynamically complete because the particle and its associated wave function do not satisfy the AR principle. (shrink)

We present an approach to understanding the origin of inertia involving the electromagnetic component of the quantum vacuum and propose this as a step toward an alternative to Mach's principle. Preliminary analysis of the momentum flux of the classical electromagnetic zero-point radiation impinging on accelerated objects as viewed by an inertial observer suggests that the resistance to acceleration attributed to inertia may be at least in part a force of opposition originating in the vacuum. This analysis avoids the ad (...) hoc modeling of particle-field interaction dynamics used previously by Haisch, Rueda, and Puthoff (Phys. Rev. A 49, 678, (1994)) to derive a similar result. This present approach is not dependent upon what happens at the particle point, but on how an external observer assesses the kinematical characteristics of the zero-point radiation impinging on the accelerated object. A relativistic form of the equation of motion results from the present analysis. Its manifestly covariant form yields a simple result that may be interpreted as a contribution to inertial mass. We note that our approach is related by the principle of equivalence to Sakharov's conjecture (Sov. Phys. Dokl. 12, 1040, (1968)) of a connection between Einstein action and the vacuum. The argument presented may thus be construed as a descendant of Sakharov's conjecture by which we attempt to attribute a mass-giving property to the electromagnetic component—and possibly other components—of the vacuum. In this view the physical momentum of an object is related to the radiative momentum flux of the vacuum instantaneously contained in the characteristic proper volume of the object. The interaction process between the accelerated object and the vacuum (akin to absorption or scattering of electromagnetic radiation) appears to generate a physical resistance (reaction force) to acceleration suggestive of what has been historically known as inertia.

The chapter juxtaposes the fairly quick and automatic thinking and decision making that constitutes everyday moral thought and action with the slower, more complicated, and more reflective thinking that steps beyond everyday moral thought. Various difficulties that can slow down everyday moral thought are catalogued in this paper. The paper explains how dealing with many of these difficulties leads to thinking about moral principles. And, even where there are not such difficulties, everyday moral thought can be challenged by repeated (...) “why?” questions. Pushed far enough, such questions have to be answered by admitting ignorance or by pointing to theses about whatever ultimately makes acts morally required, permissible, or prohibited. Such theses are moral theories. As a point about moral theories, the paper ends by pointing out a respect in which everyday moral thought is more like rule-consequentialism, contractualism, foundational pluralism, and virtue ethics than everyday moral thought is like traditional act-consequentialism.

In lieu of an abstract, here is a brief excerpt of the content:Hume on Natural Belief and Original Principles Miriam McCormick David Hume discusses anumber ofimportantbeliefs that, althoughhe himselfnever uses the term, commentators have come to call "natural beUefs." These beliefs cannotbejustified rationally but are impossible to give up. They differ from irrational beliefs because no amount of reasoning can eliminate them. There is general agreement that such a class of beliefs exists for Hume. There is differing opinion, however, concerning (...) which beliefs count as "natural." In particular, there has been much debate as to whether beliefin God is "natural" for Hume. Much of this disagreement concerning natural beliefs arises because not enough attention is paid to the different uses of"natural" in Hume. On his analysis, certain characteristics may be called "natural" insofar as their causes are found in human nature. These characteristics can be explained by reference to what Hume calls the original principles ofhuman nature. But they need not be necessary or unavoidable. It is only the original principles themselves, for Hume, that are universal and necessary for all human beings. And it is only those beliefs which necessarily result from original principles that are "natural" in a second sense: these beliefs are, according to Hume, "inseparable from the species." Only beliefs which are natural in this second sense are indispensable despite their lack ofrational grounds. Certain other beliefs, such as belief in God, are "natural" in some weaker sense, but are often taken to be "natural" in this second sense. My aim is to distinguish the different senses of"natural" for Hume and so determine which beliefs are "natural" in which senses. Natural belief Norman Kemp Smith was the first to discuss the existence ofa special class of beliefs in Hume.1 Kemp Smith first uses the term "natural beUef" in reference to the beliefin the existence ofbody. This belief, he says, is a natural belief"due to the ultimate instincts or propensities that constitute our human nature" (Kemp Smith, 151). Furthermore, this particularbeUefis not founded on reason or sense experience, yet no amount ofreasoning will cause us to give it up.2 "Certain beliefs or judgments," says Kemp Smith, "can be shown to be 'natural', 'inevitable', indispensable' and are thus removed beyond the reach of sceptical doubt" (p. 152). Two other beliefs which Kemp Smith says Volume XLX Number 1 103 MIRIAM McCORMICK Hume considere natural are belief in causal action and belief in the identity or unity ofthe self. The primary purpose of Kemp Smith's article is to demonstrate "that the establishment of a purely naturalistic conception ofhuman nature by the thorough subordination ofreason to feeling and instinct is a determining factor in Hume's philosophy" (p. 150). He developed this thesis in reaction to T. H. Green and other commentators who had claimed that Hume "merely develops to a sceptical conclusion the principles which he inherits from Locke and Berkeley" (Kemp Smith, 149). The discussion of "natural belief " is meant to show that Green is mistaken when he claims that Hume denies the existence of the external world and ofthe self. It is true that Hume says reason will not show us that such things exist. But because reason is not supreme for Hume, says Kemp Smith, we need not worry that such beliefs are not justified. Because Hume does not encourage us to give up such fundamental beliefs or even think that such an enterprise is possible, Kemp Smith maintains that, rather than being sceptical about such beliefs, Hume defends them from sceptical attack. There are certain behefs that it makes no sense to question. The doctrine of natural belief serves as an illustration of Kemp Smith's claim that Hume subordinates reason to feeling and instinct. Because his discussion òf "natural belief" is used mainly to illustrate a particular point, Kemp Smith does little more than offer a description of such beliefs. He tells us that these beliefs are inevitable and indispensable, but he does not indicate how one determines which beliefs are natural. Criteria are given for what Hume counts as a natural belief, but the means for determining ifa belief satisfies these criteria are not offered. With the publication of R. J. Butler's article, "Natural Belief and the Enigma... (shrink)

When Henri Poincaré reviewed the then competing theories of electrodynamics in the 1890s, he required their compatibility with two principles of mechanical origin—the reaction principle and the relativity principle. Historians of relativity theory have usually focused on the relativity principle and neglected or misinterpreted Poincaré’s concern with the reaction principle. In particular, most of them have interpreted his crucial article of 1900 on “Lorentz’s theory and the principle of reaction” as an attempt (...) to save this principle by assuming an electromagnetic momentum in addition to the momentum of matter. The purpose of this article is to dismiss this interpretation and show that Poincaré had the opposite intention as he spelled out the paradoxical consequences of Lorentz’s violation of the reaction principle. In doing so, he formally introduced a quantity that could later be interpreted as a genuine electromagnetic momentum, developed a fundamentally new understanding of Lorentz’s transformations in relation with the relativity principle and identified the paradoxes that Einstein would later solve by assuming the inertia of energy.

Objective: Although a main principle of medical ethics and law since the 1970s, standards of informed consent are regarded with great scepticism by many clinicans.Methods: By reviewing the reactions to and adoption of this principle of medical ethics in neurosurgery, the characteristic conflicts that emerge between theory and everyday clinical experience are emphasised and a modified conception of informed consent is proposed.Results: The adoption and debate of informed consent in neurosurgery took place in two steps. Firstly, respect for (...) patient autonomy was included into the ethical codes of the professional organisations. Secondly, the legal demands of the principle were questioned by clinicians. Informed consent is mainly interpreted in terms of freedom from interference and absolute autonomy. It lacks a constructive notion of physician–patient interaction in its effort to promote the best interest of the patient, which, however, potentially emerges from a reconsideration of the principle of beneficence.Conclusion: To avoid insufficient legal interpretations, informed consent should be understood in terms of autonomy and beneficence. A continuous interaction between the patient and the given physician is considered as an essential prerequisite for the realisation of the standards of informed consent. (shrink)

Leibniz’s conception of the relativity of motion has been discussed at length for a very long time. This paper doesn’t aim to give a full solution to this question, but to contribute to the debate by clarifying how the principle of relativity is introduced, justified and used in the “Dynamica”. Four different principles are identified : one purely geometrical, and three (meta) physical principles, which express God’s wisdom : a principle of equivalence of hypotheses linked to the (...) class='Hi'>action/reaction principle, a Galilean principle of relativity and a general principle which apply not only to rectilinear motions but also to circular ones. I argue that to appreciate the coherence of Leibniz’ approach, we should distinguish these principles more sharply than he himself did and pay more attention to their status : are they consequences of the definition of motion, consequences of the physical laws or necessary conditions for any physical theory?

I examine two claims that arise in Brown’s account of inertial motion. Brown claims there is something objectionable about the way in which the motions of free particles in Newtonian theory and special relativity are coordinated. Brown also claims that since a geodesic principle can be derived in Einsteinian gravitation, the objectionable feature is explained away. I argue that there is nothing objectionable about inertia and that while the theorems that motivate Brown’s second claim can be said to figure (...) in a deductive-nomological explanation, their main contribution lies in their explication rather than their explanation of inertial motion.

On the basis of evidence drawn from the Waste book, Westfall and Nicholas have argued that Newton arrived at his second law of motion by reflecting on the implications of the first law. I analyze another argument in the Waste book which reveals that Newton also arrived at the second law by another very different route. On this route, it is the consideration of the third law and the principle of conservation of motion—and not the first law—that prompts Newton (...) to formulate the second law. The existence of these two routes is significant because each employs a distinct kind of reasoning about forces. Whereas the Nicholas–Westfall route via the principle of inertia bears the mark of Descartes’s influence, the alternative route proceeds from the action–reaction principle, which is widely regarded as an original Newtonian contribution to mechanics. In the course of exploring this alternate route to the second law, the origins and justification of the third law are examined.Keywords: Issac Newton; Waste book; Third law of motion; Second law of motion; Richard Westfall; John Nicholas.

We critically examine the role and status probabilities, as they enter via the Quantum Equilibrium Hypothesis, play in the standard, deterministic interpretation of deBroglie’s and Bohm’s Pilot Wave Theory (dBBT), by considering interpretations of probabilities in terms of ignorance, typicality and Humean Best Systems, respectively. We argue that there is an inherent conflict between dBBT and probabilities, thus construed. The conflict originates in dBBT’s deterministic nature, rooted in the Guidance Equation. Inquiring into the latter’s role within dBBT, we find it (...) explanatorily redundant (in particular for dBBT’s solution of the Measurement Problem, which only requires that the corpuscles possess definite positions), and subject to a number of difficulties. Following a suggestion from Bell, we propose to abandon the Guidance Equation, whilst retaining dBBT’s point particle-based Primitive Ontology, with positions as local beables. The resultant theory, which we identify as a stochastic, minimally deBroglie-Bohmian theory, describes a random walk through configuration space. Its probabilities, we propose, are best understood as dispositions of possible corpuscle configurations to manifest themselves. We subsequently evaluate the merits of sdBBT vis-à-vis dBBT, such as the justification of the Symmetrisation Postulate and the violation of the Action-Reaction Principle. Not only is sdBBT an attractive Bohmian theory that, whilst retaining dBBT's virtues, overcomes many of its shortcomings; it also sparks off a number of exciting follow-up questions, such as a comparison between sdBBT and other stochastic hidden-variable theories, e.g. Nelson Stochastics, or between sdBBT and the Everett interpretation.

A local interpretation of quantum mechanics is presented. Its main ingredients are: first, a label attached to one of the “virtual” paths in the path integral formalism, determining the output for measurement of position or momentum; second, a mathematical model for spin states, equivalent to the path integral formalism for point particles in space time, with the corresponding label. The mathematical machinery of orthodox quantum mechanics is maintained, in particular amplitudes of probability and Born’s rule; therefore, Bell’s type inequalities theorems (...) do not apply. It is shown that statistical correlations for pairs of particles with entangled spins have a description completely equivalent to the two slit experiment, that is, interference instead of non locality gives account of the process. The interpretation is grounded in the experimental evidence of a point like character of electrons, and in the hypothetical existence of a wave like, the de Broglie, companion system. A correspondence between the extended Hilbert spaces of hidden physical states and the orthodox quantum mechanical Hilbert space shows the mathematical equivalence of both theories. Paradoxical behaviour with respect to the action reaction principle is analysed, and an experimental set up, modified two slit experiment, proposed to look for the companion system. (shrink)

The path-integral approach to quantum theory of continuous measurements has been developed in preceding works of the author. According to this approach the measurement amplitude determining probabilities of different outputs of the measurement can be evaluated in the form of a restricted path integral (a path integral “in finite limits”). With the help of the measurement amplitude, maximum deviation of measurement outputs from the classical one can be easily determined. The aim of the present paper is to express this variance (...) in a simpler and transparent form of a specific uncertainty principle (called the action uncertainty principle, AUP). The most simple (but weak) form of AUP is δS≳ℏ, whereS is the action functional. It can be applied for simple derivation of the Bohr-Rosenfeld inequality for measurability of gravitational field. A stronger (and having wider application) form of AUP (for ideal measurements performed in the quantum regime) is |∫ ′ t″ (δS[q]/δq(t))Δq(t)dt|≃ℏ, where the paths [q] and [Δq] stand correspondingly for the measurement output and for the measurement error. It can also be presented in symbolic form as Δ(Equation) Δ(Path) ≃ ℏ. This means that deviation of the observed (measured) motion from that obeying the classical equation of motion is reciprocally proportional to the uncertainty in a path (the latter uncertainty resulting from the measurement error). The consequence of AUP is that improving the measurement precision beyond the threshold of the quantum regime leads to decreasing information resulting from the measurement. (shrink)

In 1969 Harry Frankfurt published his hugely influential paper 'Alternate Possibilities and Moral Responsibility' in which he claimed to present a counterexample to the so-called 'Principle of Alternate Possibilities' ('a person is morally responsible for what he has done only if he could have done otherwise'). The success of Frankfurt-style cases as counterexamples to the Principle has been much debated since. I present an objection to these cases that, in questioning their conceptual cogency, undercuts many of those debates. (...) Such cases all require a counterfactual mechanism that could cause an agent to perform an action that he cannot avoid performing. I argue that, given our concept of what it is for someone to act, this requirement is inconsistent. Frankfurt-style alleged counterexamples are cases where an agent is morally responsible for an action he performs even though, the claim goes, he could not have avoided performing that action. However, it has recently been argued, e.g. by John Fischer, that a counterexample to the Principle could be a 'Fischer-style case', i.e. a case where the agent can either perform the action or do nothing else. I argue that, although Fischer-style cases do not share the conceptual flaw common to all Frankfurt-style cases, they also fail as counterexamples to the Principle. The paper finishes with a brief discussion of the significance of the Principle of Alternate Possibilities. (shrink)

Impurism says that practical factors encroach on knowledge. An important version of impurism is called ‘Threshold-Impurism,’ which says that practical factors encroach on the threshold that rational credence must pass in order for one to have knowledge.

The term action of consciousness is used to refer to an influence, such as psychokinesis or free will, that produces an effect on matter that is correlated to mental intention, but not completely determined by physical conditions. Such an action could not conserve energy. But in that case, one wonders why, when highly accurate measurements are done, occasions of non-conserved energy (generated perhaps by unconscious PK) are not detected. A possible explanation is that actions of consciousness take place (...) within the limits of the uncertainty principle. Two models are reviewed that, using the latter assumption, propose that consciousness can originate an action potential in the brain. One (that of Eccles) uses the latter assumption only, and the other (that of Burns) additionally assumes that consciousness acts, within those limits, by ordering quantum fluctuations. (shrink)

What do biologists mean when they say that to live is to react? Why was the termabreaction invented and later abandoned by the first generation of psychoanalysts? What is meant byreactionary politics? These are but a few of the questions the internationally renowned scholar JeanStarobinski answers in his conceptual history of the word pair, action and reaction.Not simply ahistory of ideas, Action and Reaction is also a semantic and philological history, a literaryhistory, a history of medicine, (...) and a history of the biological sciences. By concentrating on themoment when scientific language and ordinary language diverge, Starobinski uncovers a genealogy ofthe human and natural sciences through their usage of action and reaction as metaphors. Newton's law-- to every action there is an equal and opposite reaction -- becomes a point of departure for anexploration of the lexical and metaphorical traces left in its wake. Starobinski analyzes thescientific, literary, and political effects of the use of the terms action and reaction to describeand explain the material universe, the living body, historical events, and psychological behavior.In what he calls a "polyphonic score" -- a kind of mosaic -- he uses his subject to offer newinsights into the work of philosophers (Aristotle, Leibniz, Kant, Nietzsche, Jaspers), scientists(Newton, Bichat, Bernard, Bernheim, Freud), and writers (Diderot, Constant, Balzac, Poe, Valry).Ultimately, the book explores the power and danger of metaphorical language and questions theconvergence and collapse of scientific and moral explanations of the universe.

In the development of governmental policy for artificial intelligence that is informed by ethics, one avenue currently pursued is that of drawing on “AI Ethics Principles”. However, these AI Ethics Principles often fail to be actioned in governmental policy. This paper proposes a novel framework for the development of ‘Actionable Principles for AI’. The approach acknowledges the relevance of AI Ethics Principles and homes in on methodological elements to increase their practical implementability in policy processes. As a case study, elements (...) are extracted from the development process of the Ethics Guidelines for Trustworthy AI of the European Commission’s “High Level Expert Group on AI”. Subsequently, these elements are expanded on and evaluated in light of their ability to contribute to a prototype framework for the development of 'Actionable Principles for AI'.

Basically, I agree with Chen Lai's views on the difficulties of translating ancient Chinese thinking into modern Western idioms. The problem is not only due to the dependence of the meaning of terms upon their use in a specific context. The problem is already there for Chinese scholars themselves: It is the translation of words or concepts from a traditional learned context related to specific questions into modern Chinese language. In order to succeed, one has to realize, first, that modern (...) colloquial Chinese is divorced from classical Chinese categories and, secondly, that philosophical vocabulary in modern Chinese is contaminated by Western philosophical categories.

The present paper investigates why logical empiricists remained silent about one of the most philosophy-laden matters of theoretical physics of their day, the principle of least action (PLA). In the two decades around 1900, the PLA enjoyed a remarkable renaissance as a formal unification of mechanics, electrodynamics, thermodynamics, and relativity theory. Taking Ernst Mach's historico-critical stance, it could be liberated from much of its physico-theological dross. Variational calculus, the mathematical discipline on which the PLA was based, obtained a (...) new rigorous basis. These three developments prompted Max Planck to consider the PLA as formal embodiment of his convergent realist methodology. Typically rejecting ontological reductionism, David Hilbert took the PLA as the key concept in his axiomatizations of physical theories. It served one of the main goals of the axiomatic method: ''deepening the foundations.'' Although Moritz Schlick was a student of Planck's, and Hans Hahn and Philipp Frank enjoyed close ties to Gottingen, the PLA became a veritable Shibboleth to them. Rather than being worried by its historical connections with teleology and determinism, they erroneously identified Hilbert's axiomatic method tout court with Planck's metaphysical realism. Logical empiricists' strict containment policy against metaphysics required so strict a separation between physics and mathematics to exclude even those features of the PLA and the axiomatic method not tainted with metaphysics.

Ernest Becker's theory about death denial is one example of depth psychological theory. Because very important features of Becker's theory have now successfully and singularly met the rigorous empirical testing of Terror Management Theory (TMT), it must be concluded that the theory of death denial stands apart from and above alternative depth psychological theories in explaining human behavioral and attitudinal motivation. Nevertheless, TMT only touches the surface of Becker's theory in the round. This essay looks at how Becker's wider theories (...) of death denial are applied to (1) personal psychological, (2) social psychological, (3) political, and (4) spiritual aspects of human experience and suggests that what Becker has given us is an organizing principle, a theory of considerable integrative, explanatory, and interpretive power, for a broadly interdisciplinary social science of human behavior.

Despite the importance of the variational principles of physics, there have been relatively few attempts to consider them for a realistic framework. In addition to the old teleological question, this paper continues the recent discussion regarding the modal involvement of the principle of least action and its relations with the Humean view of the laws of nature. The reality of possible paths in the principle of least action is examined from the perspectives of the contemporary metaphysics (...) of modality and Leibniz's concept of essences or possibles striving for existence. I elaborate a modal interpretation of the principle of least action that replaces a classical representation of a system's motion along a single history in the actual modality by simultaneous motions along an infinite set of all possible histories in the possible modality. This model is based on an intuition that deep ontological connections exist between the possible paths in the principle of least action and possible quantum histories in the Feynman path integral. I interpret the action as a physical measure of the essence of every possible history. Therefore only one actual history has the highest degree of the essence and minimal action. To address the issue of necessity, I assume that the principle of least action has a general physical necessity and lies between the laws of motion with a limited physical necessity and certain laws with a metaphysical necessity.

The principle of least action (PLA) has often been cited as a counterexample to the dominant mode of causal explanation in physics. In particular, PLA seems to involve an appeal to final causes or some other teleological ideology. However, Ben-Menahem (Causation in science, Princeton University Press, Princeton, 2018) argues that such implications no longer apply given that PLA can be recovered as limiting case from quantum theory. In this paper, I argue that the metaphysical implications of PLA-based explanations (...) are not undermined by its status as derivative. However, I contend that PLA functions as a diachronic constraint that licenses explanations by constraint (Lange, Because without cause: non-casual explanations in science and mathematics. Oxford University Press, Oxford, 2016). PLA-based explanations, on this account, are non-causal but also differ from familiar cases of teleological explanations in several respects. (shrink)

We begin by presenting William of Ockham's various formulations of his principle of parsimony, Ockham's Razor. We then define a reaction mechanism and tell a personal story of how Ockham's Razor entered the study of one such mechanism. A small history of methodologies related to Ockham's Razor, least action and least motion, follows. This is all done in the context of the chemical (and scientific) community's almost unthinking acceptance of the principle as heuristically valuable. Which is (...) not matched, to put it mildly, by current philosophical attitudes toward Ockham's Razor. What ensues is a dialogue, pro and con. We first present a context for questioning, within chemistry, the fundamental assumption that underlies Ockham's Razor, namely that the world is simple. Then we argue that in more than one pragmatic way the Razor proves useful, without at all assuming a simple world. Ockham's Razor is an instruction in an operating manual, not a world view. Continuing the argument, we look at the multiplicity and continuity of concerted reaction mechanisms, and at principal component and Bayesian analysis (two ways in which Ockham's Razor is embedded into modern statistics). The dangers to the chemical imagination from a rigid adherence to an Ockham's Razor perspective, and the benefits of the use of this venerable and practical principle are given, we hope, their due.

The tragedies of the past decade have led to an identity crisis among humanitarians. Respecting traditional principles of neutrality and impartiality and operating procedures based on consent has created as many problems as it has solved.

A new evolutionary concept is presented, based on the principle of biological diversity by organismal adaptation, more specifically the origin of the first variations and the process leading to speciation. The article suggests the mechanism of stimulation as the major promoter of genetic variation, making an overall assessment and accurate to the natural phenomenon responsible for this evolutionary step. Constantly, environmental forces interact with the organism, favoring changes to the organs toward adaptation. Stimulation focuses on this action?reaction (...) between organism and environment, trying to decipher the causes/consequences resulting. The article also addresses possible relationships and constraints with neo-Darwinism. (shrink)

Slowly, we are gaining a deeper understanding of the persisting psychological trauma experienced by students at colonial universities, and beginning to recognize that the Eurocentric curricula and pedagogies must change if students such as the “born-frees” in post-Apartheid South Africa are to flourish. In this article, I present a sub-Saharan African concept of “the ethical teacher,” and use this to ground a “ubiquitous action-reaction” teaching model. I use these concepts to develop a decolonized pedagogy – a teaching methodology (...) that avoids a number of harmful colonial teaching practices in philosophy. I suggest a number of novel ways of accommodating a “decolonized education” with a view to inspiring teachers of philosophy in colonial countries globally. I propose a new, malleable pedagogical model that is particularly useful in the colonial context, since its uniqueness lies in the African ethical framework that grounds it. However, I contend that philosophy educators globally will benefit from taking the principles proposed in this article seriously. (shrink)
