The article attempts to reconstruct the solution of the fundamental for the Anglo-American historical school (T. Kuhn, I. Lakatos, P. Feyerabend) problem of incommensurability, proposed by Helmut Spinner, a prominent representative of German critical rationalism (hereinafter referred to as CR). It is shown that this solution became possible on the way of rethinking the shortcomings of the orthodox CR of K. Popper and H. Albert, the main one of which Spinner saw in “scarcity” pluralism and criticism. To overcome it, he (...) considered it necessary to develop the KR in the direction of “pluralistically extended fallibilist criticism” of the Feyerabend persuasion with some innovations. Spinner’s new version of the CR, was based on the following three fundamental principles: 1) the principle of radicalization of pluralism (hyperpluralism); 2) the principle of the infallibility of fallibilism (hyperfallibilism) (Fallubilität des Fallibilismus); 3) the principle (requirement) of the minimum commensurability of theories. The essence and content of the third principle is as follows. Minimal commensurability means that competing theories are commensurate, at least in one essential point: commensurability of this kind is mediated by “transition theories”. Incommensurable theories are by no means useless, for thanks to “transition theories” they can become commensurate, at least in a minimal sense. And this minimum commensurability is the most essential and desirable for theoretical pluralism, since only it provides the maximum criticism of alternative theories, thereby expanding the possibilities of confrontation and strengthening pluralistic criticism in general.

COVID-19 pandemic has claimed thousands of lives around the world. Among the casualties are doctors, nurses, and other health care professionals. Those who defy the danger of death and continue to render their services have to deal with psychological and mental stress due to the lack of protective measures and equipment, the overwhelming number of patients, and the experience of discrimination. In fact, some left their job. In this paper, I will argue that the motivation of health care professionals and (...) the outcome of their sacrifices, as against assuring personal safety, can be explained by the principle of the common good. First, they are faithful to their oath as health care professionals since it is their commitment as part of an institution that assumes the responsibility of providing health care to people in need. Second, restoring the patients’ condition goes beyond health issues since the recovery of each COVID-19 patient diminishes the spread of the virus, which, if not for the care of HCPs, could worsen the situation with snowballing consequences to society as a whole. While it is expected for any health care professional as a frontliner in times of pandemic, their motivation to serve exemplifies the greater value for the common good. (shrink)

Principles of Charity have become central features of any plausible theory of interpretation. The trick has been to explain how the truth of the text to appear without abandoning one’s critical resources in the process. I argue that Gadamer’s discussion of “the logic of question and answer,” when applied to textual interpretation, functions as a principle of charity provides the right balance between being too liberal and being too critical.

The subject of this article is the Principle of Characterization—the most controversial principle of Alexius Meinong’s Theory of Objects. The aim of this text is twofold. First of all, to show that Bertrand Russell’s well-known objection to the Principle of Characterization can be reformulated against contemporary unrestricted interpretations of it. Second, to propose an alternative formulation of this principle. This refers to the methodology of metaphysics and is based on the distinction between pre-theoretical and theoretical languages. (...) The proposed formulation fits well with every type of contemporary interpretation of the Theory of Objects and helps to overcome Russell’s criticism. (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)

Canonical defenders of the principle of sufficient reason (PSR), such as Leibniz and Spinoza, are metaphysical foundationalists of one stripe or another. This is curious since the PSR—which says that everything has a ground, cause, or explanation—in effect, denies fundamental entities. In this paper, I explore the apparent inconsistency between metaphysical foundationalism and approaches to metaphysical system building that are driven by a commitment to the PSR. I do so by analyzing how Indian Buddhist philosophers arrive at foundationalist and (...) anti-foundationalist positions motivated by implicit commitments to different versions of the PSR. I begin by introducing the Buddhist principle of dependent origination (pratītyasamutpāda) as a proto-PSR that is restricted to causal explanation. Next, I show how Vasubandhu’s Sautrāntika Abhidharma metaphysics is shaped by a qualified commitment to both causal and metaphysical grounding versions of the PSR. I then reveal how Nāgārjuna’s Madhyamaka metaphysics is driven by an unrestricted and exceptionless commitment to causal and metaphysical grounding versions of the PSR. Finally, I consider how Nāgārjuna’s account may put him in a unique position to respond to a common contemporary objection to the PSR from necessitarianism. I conclude by addressing a competing interpretation on which Nāgārjuna is best understood as an anti-rationalist rather than an uber-rationalist, as I characterize him. (shrink)

In Bayesian epistemology, the problem of the priors is this: How should we set our credences (or degrees of belief) in the absence of evidence? That is, how should we set our prior or initial credences, the credences with which we begin our credal life? David Lewis liked to call an agent at the beginning of her credal journey a superbaby. The problem of the priors asks for the norms that govern these superbabies. -/- The Principle of Indifference gives (...) a very restrictive answer. It demands that such an agent divide her credences equally over all possibilities. That is, according to the Principle of Indifference, only one initial credence function is permissible, namely, the uniform distribution. In this paper, we offer a novel argument for the Principle of Indifference. I call it the Argument from Accuracy. (shrink)

I argue that Émilie Du Châtelet breaks with Christian Wolff regarding the scope and epistemological content of the principle of sufficient reason, despite his influence on her basic ontology and their agreement that the principle of sufficient reason has foundational importance. These differences have decisive consequences for the ways in which Du Châtelet and Wolff conceive of science.

This volume of translations unites three shorter works by Arthur Schopenhauer that expand on themes from his book The World as Will and Representation. In On the Fourfold Root he takes the principle of sufficient reason, which states that nothing is without a reason why it is, and shows how it covers different forms of explanation or ground that previous philosophers have tended to confuse. Schopenhauer regarded this study, which he first wrote as his doctoral dissertation, as an essential (...) preliminary to The World as Will. On Will in Nature examines contemporary scientific findings in search of corroboration of his thesis that processes in nature are all a species of striving towards ends; and On Vision and Colours defends an anti-Newtonian account of colour perception influenced by Goethe's famous colour theory. This is the first English edition to provide extensive editorial notes on the different published versions of these works. (shrink)

Resumen Tomando como punto de partida las condiciones del contexto socio político donde se originó el brote epidémico del virus SARS-CoV-2, los autores analizan la influencia que tuvo el principio de beneficencia como una de las razones éticas que condujeron al oftalmólogo Li Wenliang a alertar a través de la red social Weibo, sobre el surgimiento de un brote epidémico distinto, por su agresividad, al del SARS. Se asume que dicho principio puede comprenderse a partir de un enfoque donde se (...) conjugan referentes occidentales -la primera formulación del imperativo categórico kantiano y el legado hipocrático- y orientales -el principio del Ren o humanidad, derivado del pensamiento confuciano-. El artículo concluye señalando que en un mundo interrelacionado donde las prácticas médicas tienen fundamentos científicos universales, es posible tomar decisiones éticas médicas válidas para diferentes contextos culturales, siempre y cuando se continúe avanzando en el terreno de un diálogo inter-civilizatorio con perspectiva horizontal.This article analyzes the influence of the principle of beneficence as one of the ethical reasons that led ophthalmologist Li Wenliang to alert, using the Weibo plaform, about the emergence of an epidemic outbreak different from SARS. Accordingly, we discuss the socio-political context of the SARS-CoV-2 epidemic in China. We assume that the principle of beneficence might be understood from an approach combining Western references - the first formulation of the Kantian categorical imperative and the Hippocratic legacy - with Oriental ones - the Ren or humanity, derived from Confucian thought. We conclude that in an interrelated world, with medical practices having universal scientific foundations, it is possible to validate medical ethical decisions from different cultural contexts, as long as progress continues in the field of an inter-civilizational dialogue with a horizontal perspective.

In this article, I derive a weak version of Kant's categorical imperative within an informal game-theoretic framework. More specifically, I argue that Hobbesian agents would choose what I call the weak principle of universalization, if they had to decide on a rule of conflict resolution in an idealized but empirically defensible hypothetical decision situation. The discussion clarifies (i) the rationality requirements imposed on agents, (ii) the empirical conditions assumed to warrant the conclusion, and (iii) the political institutions that are (...) necessary to implement the derived principle. The analysis demonstrates the moral significance of the weak principle of universalization and its epistemic advantage over the categorical imperative. (shrink)

This article offers a novel, conservative account of material constitution, one that incorporates sortal essentialism and features a theory of dominant sortals. It avoids coinciding objects, temporal parts, relativizations of identity, mereological essentialism, anti-essentialism, denials of the reality of the objects of our ordinary ontology, and other departures from the metaphysic implicit in ordinary ways of thinking. Defenses of the account against important objections are found in Burke 1997, 2003, and 2004, as well as in the often neglected six paragraphs (...) that conclude section V of this article. (shrink)

In a recent article, Elliot Sober responds to challenges to a counter-example that he posed some years earlier to the Principle of the Common Cause (PCC). I agree that Sober has indeed produced a genuine counter-example to the PCC, but argue against the methodological moral that Sober wishes to draw from it. Contrary to Sober, I argue that the possibility of exceptions to the PCC does not undermine its status as a central assumption for methods that endeavor to draw (...) causal conclusions from statistical data. 1 The PCC and the counter-example 2 Making non-stationary time series stand still 3 Sober's alternative.

The principle of total evidence says that all relevant information should be considered when making an inference about a hypothesis. In this article, we argue that the criminalist’s paradox from the literature on the methodology of forensic science constitutes a counterexample against the principle of total evidence. The paradox arises, for example, when a forensic scientist uses the results from other forensic procedures to inform their own analysis. In such cases, their results can become more reliable, but at (...) the same time also dependent on those other forensic results and therefore less useful for decisions in court cases. Consequently, such influences are generally avoided in forensic science. We argue that structurally similar problems plague also other scientific disciplines, anticipate an objection to the counterexample, and propose two new versions of the principle of total evidence that do not fall prey to the criminalist’s paradox.

The term “principle of sufficient reason” (PSR) was coined by Leibniz, and he is often regarded as its paradigmatic proponent. But as Leibniz himself often insisted, he was by no means the first philosopher to appeal to the idea that everything must have a reason. Histories of the principle attribute versions of it to various ancient authors. A few of these studies include—or at least do not exclude—medieval philosophers; one finds the PSR in Abelard, another finds it in (...) Aquinas. And while Leibniz retains pride of place in these histories, Spinoza is sometimes said to precede him “in appreciating the importance of the Principle and placing it at the center of his philosophical system.” In this paper, the author argues that the same should be said of the Islamic philosopher Avicenna. Writing 600 years before his early modern counterparts, Avicenna routinely and consistently appeals to the PSR in generating his metaphysical system. The paper aims first to establish that Avicenna deserves a position of prominence in histories of the PSR, and then to consider how he addresses certain challenges to the PSR, especially the threat posed by necessitarianism.

This collection of original papers on the special and general theories of relativity constitutes an indispensable part of a library on relativity. Here are the 11 papers that forged the general and special theories of relativity: seven papers by Einstein, plus two papers by Lorentz and one each by Minkowski and Weyl.

James Lenman argues that consequentialism fails as a moral theory because it is impossible to predict the long-term consequences of our actions. I agree that it is impossible to predict the long-term consequences of actions, but argue that this does not count as a strike against consequentialism. I focus on the principle of indifference, which tells us to treat unforeseeable consequences as cancelling each other out, and hence value-neutral. I argue that though we cannot defend this principle independently, (...) we cannot do without it in practical rationality. Thus abandoning the principle of indifference would involve abandoning all of rationality, not just consequentialist reasoning. I suggest that we should understand the principle as P. F. Strawson understands inductive reasoning – as being part of rationality. Correspondence:c1 [email protected]. (shrink)

Leibniz, and many following him, saw the Principle of Sufficient Reason (PSR) as pivotal to a scientific (demonstrated) metaphysics. Against this backdrop, Kant is expected to pay close attention to PSR in his reflections on the possibility of metaphysics, which is his chief concern in the Critique of Pure Reason. It is far from clear, however, what has become of PSR in the Critique. On one reading, Kant has simply turned it into the causal principle of the Second (...) Analogy. On a different reading, PSR is but the supreme principle of reason, which roughly states that, if the conditioned is given, so is the unconditioned. On my reading, PSR appears in the guises of both the causal principle and the supreme principle. This twofold specification, I argue, is key to understanding (i) Kant’s allegations that past metaphysicians failed to prove PSR, (ii) his own Critical account of the possibility of metaphysics in both of its parts (ontology and metaphysics proper), and (iii) his nuanced answer to the contentious question about the relation between physical inquiry and metaphysical reasoning about nature (both being quests for reasons).

The surprise minimization principle has been applied to explain various cognitive processes in humans. Originally describing perceptual and active inference, the framework has been applied to different types of decision making including long-term policies, utility maximization and exploration. This analysis extends the application of surprise minimization to a multi-agent setup and shows how it can explain the emergence of social rules and cooperation. We further show that in social decision-making and political policy design, surprise minimization is superior in many (...) aspects to the classical approach of maximizing utility. Surprise minimization shows directly what value freedom of choice can have for social agents and why, depending on the context, they enter into cooperation, agree on social rules, or do nothing of the kind.

This article argues that a successful answer to Hume's problem of induction can be developed from a sub-genre of philosophy of science known as formal learning theory. One of the central concepts of formal learning theory is logical reliability: roughly, a method is logically reliable when it is assured of eventually settling on the truth for every sequence of data that is possible given what we know. I show that the principle of induction (PI) is necessary and sufficient for (...) logical reliability in what I call simple enumerative induction. This answer to Hume's problem rests on interpreting PI as a normative claim justified by a non-empirical epistemic means-ends argument. In such an argument, a rule of inference is shown by mathematical or logical proof to promote a specified epistemic end. Since the proof concerning PI and logical reliability is not based on inductive reasoning, this argument avoids the circularity that Hume argued was inherent in any attempt to justify PI. (shrink)

Faced with strong arguments to the effect that Leibniz''sPrinciple of the Identity of Indiscernibles (PII) is not a necessary truth, many supporters of the Principle have staged a strategic retreat to the claim that it is contingently true in this, the actual, world. The purpose of this paper is to examine the status of the various forms of PII in both classical and quantum physics, and it is concluded that this latter view is at best doubtful, at worst, simply (...) wrong.

abstract: Leibniz holds that there are no two perfectly similar things, a doctrine he calls the Principle of the Identity of Indiscernibles (the PII). What is his attitude toward its modal status? Most commentators hold that the principle is best understood as a necessary truth because it is allegedly entailed by doctrines such as the conceptual containment theory of truth, the Principle of Sufficient Reason (the PSR), and the denial of purely extrinsic denominations, which are arguably regarded (...) by Leibniz as necessary truths. In this paper, I argue against this consensus and show that (1) neither the conceptual containment theory of truth, nor the PSR, nor the denial of purely extrinsic denominations give Leibniz a good reason to hold that the PII is necessary; (2) Leibniz says that the PII is contingent in the correspondence with Clarke and not for dialectical reasons; and (3) the argument that Leibniz gives for the PII in §21 of his Fifth Letter to Clarke has been misunderstood; properly interpreted, it gives Leibniz a cogent argument rooted in some of his most important doctrines for the conclusion that the PII is a contingent truth.

Events between which we have no epistemic reason to discriminate have equal epistemic probabilities. Bertrand’s chord paradox, however, appears to show this to be false, and thereby poses a general threat to probabilities for continuum sized state spaces. Articulating the nature of such spaces involves some deep mathematics and that is perhaps why the recent literature on Bertrand’s Paradox has been almost entirely from mathematicians and physicists, who have often deployed elegant mathematics of considerable sophistication. At the same time, the (...) philosophy of probability has been left out. In particular, left out entirely are the philosophical ground of the principle of indifference, the nature of the principle itself, the stringent constraint this places on the mathematical representation of the principle needed for its application to continuum sized event spaces, and what these entail for rigour in developing the paradox itself. This book puts the philosophy and its entailments back in and in so doing casts a new light on the paradox, giving original analyses of the paradox, its possible solutions, the source of the paradox, the philosophical errors we make in attempting to solve it and what the paradox proves for the philosophy of probability. The book finishes with the author’s proposed solution—a solution in the spirit of Bertrand’s, indeed—in which an epistemic principle more general than the principle of indifference offers a principled restriction of the domain of the principle of indifference.

The Principle of Sufficient Reason must be justified dialectically: by showing the disastrous consequences of denying it. We formulate a version of the Principle that is restricted to basic natural facts, which entails the obtaining of at least one supernatural fact. Denying this principle results in extreme empirical skepticism. We consider six current theories of empirical knowledge, showing that on each account we cannot know that we have empirical knowledge unless we all have a priori knowledge of (...) the PSR. We consider objections based on Neo-Humeanism and the essentiality of origins, and we consider the possibility that we have empirical knowledge without knowing it. (shrink)

This article concerns the nature of reason in the work of the Twentieth Century Catholic theologian Erich Przywara and Georg Wilhelm Friedrich Hegel. The discussion centers on three interlocking issues: the question whether proper thinking submits to or transgresses the principle of non-contradiction; the relationship between reason and history; the theological concern with distinguishing the “history of reason” and the divine life. It is argued that both Hegel and Przywara give an account of reason where there are moments of (...) contradiction, and that this is a necessary feature of historical existence. Further, while Przywara and others are concerned with Hegel’s making reason’s reconciliation of contradiction in history identical with the divine life, I argue that although this is a real concern, Hegel’s account is more equivocal than normally admitted. Finally, I argue that the distinguishing feature between Przywara and Hegel is what happens after the moment of contradiction; that is where we see the most important difference between an analogical and a dialectical account of reason.

We argue that David Lewis’s principal principle implies a version of the principle of indifference. The same is true for similar principles that need to appeal to the concept of admissibility. Such principles are thus in accord with objective Bayesianism, but in tension with subjective Bayesianism. 1 The Argument2 Some Objections Met.

The chapter begins by contrasting two approaches to the analysis of hope, one which takes its departure from a view broadly shared by Hobbes, Locke and Hume, another which fits better with Aquinas's definition of hope. The former relies heavily on a sharp distinction between the cognitive and conative aspects of hope. It is argued that while this approach provides a valuable source of insights, its focus is too narrow and it rests on a problematic rationalist psychology. The chapter then (...) discusses the phenomenology of hope with particular reference to the contrast between the lived experience of expectation and anticipation. This leads to a discussion of the value of hope. My thesis here is that when philosophers reflect on hope, they bring along background, tacit assumptions regarding its worth, which I attempt to make explicit. Finally the chapter identifies a second kind of philosophical reflection on hope, which is concerned not so much with the logic or value of hope as with hope understood as a 'principle.'. (shrink)

The principle of sufficient reason threatens modal collapse. Some have suggested that by appealing to the indefinite extensibility of contingent truth, the threat is neutralized. This paper argues that this is not so. If the indefinite extensibility of contingent truth is developed in an analogous fashion to the most promising models of the indefinite extensibility of the concept set, plausible principles permit the derivation of modal collapse.

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.
