Binding specificity is a centrally important concept in molecular biology, yet it has received little philosophical attention. Here I aim to remedy this by analyzing binding specificity as a causal property. I focus on the concept’s role in drug design, where it is highly prized and hence directly studied. From a causal perspective, understanding why binding specificity is a valuable property of drugs contributes to an understanding of causal selection—of how and why scientists distinguish between causes, not just causes from (...) noncauses. In particular, the specificity of drugs is precisely what underwrites their value as experimental interventions on biological processes. (shrink)

Imperatives cannot be true, but they can be obeyed or binding: `Surrender!' is obeyed if you surrender and is binding if you have a reason to surrender. A pure declarative argument — whose premisses and conclusion are declaratives — is valid exactly if, necessarily, its conclusion is true if the conjunction of its premisses is true; similarly, I suggest, a pure imperative argument — whose premisses and conclusion are imperatives — is obedience-valid (alternatively: bindingness-valid) exactly if, necessarily, its conclusion is (...) obeyed (alternatively: binding) if the conjunction of its premisses is. I argue that there are two kinds of bindingness, and that a vacillation between two corresponding variants of bindingness-validity largely explains conflicting intuitions concerning the validity of some pure imperative arguments. I prove that for each of those two variants of bindingness-validity there is an equivalent variant of obedience-validity. Finally, I address alternative accounts of pure imperative inference.

Numerous societal issues, from climate change to pandemics, require public engagement with scientific research. Such engagement reveals challenges that can arise when experts communicate with laypeople. One of the most common frameworks for framing these communicative interactions is the deficit model of science communication, which holds that laypeople lack scientific knowledge and/or positive attitudes towards science, and that imparting knowledge will fill knowledge gaps, lead to desirable attitude/behavior changes, and increase trust in science. §1 introduces the deficit model in more (...) detail and shows that adhering to this model often fails to achieve its aims, which motivates the main question of this chapter: how can Ludwik Fleck’s theory of thinking collectives address the persistent problem of deficit approaches in science communication? I suggest that it can do so by exposing the deficit model’s implicit assumption of an expert-lay divide. Accordingly, §2 lays out Fleck’s theory and §3 contrasts it with contemporary debates about science communication. Following this descriptive work, §4 draws on Fleck’s ideas to make four concrete suggestions for further questioning the expert-lay divide. (shrink)

According to Hempel's paradox, evidence (E) that an object is a nonblack nonraven confirms the hypothesis (H) that every raven is black. According to the standard Bayesian solution, E does confirm H but only to a minute degree. This solution relies on the almost never explicitly defended assumption that the probability of H should not be affected by evidence that an object is nonblack. I argue that this assumption is implausible, and I propose a way out for Bayesians. Introduction Hempel's (...) paradox, the standard Bayesian solution, and the disputed assumption Attempts to defend the disputed assumption Attempts to refute the disputed assumption A way out for Bayesians Conclusion.

The Principal Principle (PP) says that, for any proposition A, given any admissible evidence and the proposition that the chance of A is x%, one's conditional credence in A should be x%. Humean Supervenience (HS) claims that, among possible worlds like ours, no two differ without differing in the spacetime-point-by-spacetime-point arrangement of local properties. David Lewis (1986b, 1994a) has argued that PP contradicts HS, and the validity of his argument has been endorsed by Bigelow et al. (1993), Thau (1994), Hall (...) (1994), Strevens (1995), Ismael (1996), Hoefer (1997), and Black (1998). Against this consensus, I argue that PP might not contradict HS: Lewis's argument is invalid, and every attempt – within a broad class of attempts – to amend the argument fails. (shrink)

The paper challenges the view that public justification sits well with emancipatory and egalitarian intuitions. I distinguish between the depth, scope and the purchase of the discursive standing that such justification allocates, and situate within this matrix Rawls’s view of public justification. A standard objection to this view is that public justification should be more inclusive in scope. This is both plausible and problematic in emancipatory and egalitarian terms. If inclusive public justification allocates discursive standing that is rich in purchase, (...) as seems desirable in emancipatory terms, it may be unable to allocate equal standing to all relevant people. And if it is to allocate equal standing, then the equality of that standing should be construed in terms that allow for unequal discursive purchase. (shrink)

The problem of evil is an ideal topic for experimental philosophy. Suffering--which is at the heart of most prominent formulations of the problem of evil--is a universal human experience and has been the topic of careful reflection for millennia. However, interpretations of suffering and how it bears on the existence of God are tremendously diverse and nuanced. We might immediately find ourselves wondering why (and how!) something so universal might be understood in so many different ways. Why does suffering push (...) some people toward atheism while pushing others toward deeper faith? What cultural, psychological, or sociological differences account for this diversity of responses? And, importantly, what light might this diversity of responses shed on the problem of evil and how it has been formulated by philosophers in recent years? The primary aim of this paper is to highlight how the tools and resources of experimental philosophy might be fruitfully applied to the problem of evil. In the first section, we review some recent work in this area and describe the current state of this emergent body of literature. In the second section, we review the broader and more recent theoretical developments on the problem of evil. Finally, in the final section, we outline some potential areas of future empirical research that we see as especially promising given those developments. (shrink)

David Lewis (1980) proposed the Principal Principle (PP) and a “reformulation” which later on he called ‘OP’ (Old Principle). Reacting to his belief that these principles run into trouble, Lewis (1994) concluded that they should be replaced with the New Principle (NP). This conclusion left Lewis uneasy, because he thought that an inverse form of NP is “quite messy”, whereas an inverse form of OP, namely the simple and intuitive PP, is “the key to our concept of chance”. I argue (...) that, even if OP should be discarded, PP need not be. Moreover, far from being messy, an inverse form of NP is a simple and intuitive Conditional Principle (CP). Finally, both PP and CP are special cases of a General Principle (GP); it follows that so are PP and NP, which are thus compatible rather than competing. (shrink)

In this article I propose an original view of the nature of shared intention. In contrast to psychological views (Bratman, Searle, Tuomela) and normative views (Gilbert), I argue that both functional roles played by attitudes of individual participants and interpersonal obligations are factors of central and independent significance for explaining what shared intention is. It is widely agreed that shared intention (I) normally motivates participants to act, and (II) normally creates obligations between them. I argue that the view I propose (...) can explain why it is not a mere accident that both (I) and (II) are true of shared intention, while psychological and normative views cannot. The basic idea is that shared intention involves a structure of attitudes of individuals –including, most importantly, attitudes of reliance – which normally plays the relevant motivating roles and creates the relevant obligations.

In Wollstonecraft’s early writings, she articulates the foundational theological and philosophical principles that would underpin her work throughout her career. One difference between her early and later work lies in the way that the values to which she refers are combined. Whereas Wollstonecraft at first appeals to the separate ideals of independence, equality, and virtue, from the 1790s onwards she integrates these into a characteristic republican framework that was in common use amongst dissenting theorists at the time. The set of (...) values on which Wollstonecraft draws, and the version of the republican framework that she develops, closely resemble those of Richard Price with whose work she was familiar. Examining the structural similarities between their respective models, I argue, gives us an insight into the systematic manner of aspects of Wollstonecraft’s own thought. It also allows us to see how Wollstonecraft goes beyond the republicanism of Price and others as she develops her own feminist solutions to the problems of structural domination. (shrink)

Must philosophers incorporate tools of experimental science into their methodological toolbox? I argue here that they must. Tallying up all the resources that are now part of standard practice in analytic philosophy, we see the problem that they do not include adequate resources for detecting and correcting for their own biases and proclivities towards error. Methodologically sufficient resources for error- detection and error-correction can only come, in part, from the deployment of specific methods from the sciences. However, we need not (...) imagine that the resulting methodological norms will be so empirically demanding as to require that all appeals to intuition must first be precertified by a thorough vetting by teams of scientists. Rather, I sketch a set of more moderate methodological norms for how we might best include these necessary tools of experimental philosophy. (shrink)

Reasoning over our knowledge bases and theories often requires non-deductive inferences, especially – but by no means only – when commonsense reasoning is the case, i.e. when practical agency is called for. This kind of reasoning can be adequately formalized via the notion of supraclassical consequence, a non-deductive consequence tightly associated with default and non-monotonic reasoning and featuring centrally in abductive, inductive, and probabilistic logical systems. In this paper, we analyze core concepts and problems of these systems in the light (...) of supraclassical consequence. (shrink)

Abstract: Context: grapevine leaves are an important agricultural product that is used in many Middle Eastern dishes. The species from which the grapevine leaf originates can differ in terms of both taste and price. Method: In this study, we build a deep learning model to tackle the problem of grape leaf classification. 500 images were used (100 for each species) that were then increased to 10,000 using data augmentation methods. Convolutional Neural Network (CNN) algorithms were applied to build this model (...) specifically using the pre-trained model on top of the VGG16 architecture. Then, dense layers were added to classify the output of the Convolutional layers and classify outputs to the five classes (species) the leaf belonged to. Results: It was found that feature extraction without fine-tuning the convolutional layers yielded poor results, about 86% accuracy, while training the whole network along with some data preprocessing gave the best results, about 99.45% accuracy on the testing dataset. Conclusions: The proposed CNN model is an effective one for the problem of classification of grape leaf species. (shrink)

Patient-funded trials are gaining traction as a means of accelerating clinical translation. However, such trials sidestep mechanisms that promote rigor, relevance, efficiency, and fairness. We recommend that funding bodies or research institutions establish mechanisms for merit review of patient-funded trials, and we offer some basic criteria for evaluating PFT protocols.

This article examines whether it is possible to uphold one form of deflationism towards metaphysics, ontological pluralism, whilst maintaining metaphysical realism. The focus therefore is on one prominent deflationist who fits the definition of an ontological pluralist, Eli Hirsch, and his self-ascription as a realist. The article argues that ontological pluralism is not amenable to the ascription of realism under some basic intuitions as to what a “realist” position is committed to. These basic intuitions include a commitment to more than (...) a stuff-ontology, and a view that realism carries with it more than a rejection of idealism. This issue is more than merely terminological. The ascription of realism is an important classification in order to understand what sorts of entities can be the truthmakers within a given theory. “Realism” is thus an important term to understand the nature of the entities that a given theory accepts into its ontology.

Mango is an economically significant fruit crop cultivated in various tropical and subtropical regions around the world. However, the productivity and quality of mangoes can be severely impacted by a range of pests. This research paper introduces an innovative approach to identify mango pests using an expert system. The expert system integrates knowledge from entomology and plants to provide accurate identification of common mango pests. The paper outlines the development and implementation of the expert system using Clips shell, which utilizes (...) rule-based techniques to analyze symptoms associated with mango pests. By inputting observed symptoms, such as leaf spots, fruit damage, leaf mild and stem cankers the system can accurately identify the specific pest species affecting the mango tree. For each pest, the paper discusses their specific symptoms and Favorable conditions that affect the mango plant. By understanding the identification and symptoms of these pests, mango growers and agricultural professionals can implement appropriate pest management strategies to mitigate the economic losses caused by these insects. The research presented in this paper aims to contribute to the body of knowledge on mango pest management, facilitating sustainable mango production and ensuring the availability of high-quality mangoes in global markets.

In this paper I consider the possibility of a kind of a priori cognition that serves the purposes of metaphysics, given that metaphysics involves the search for modal knowledge. Necessary or, better, modal knowledge is a priori; so metaphysical knowledge is likewise a priori. Here I argue that intuition is the route to modal knowledge in metaphysics, and I insist that conceivability or knowledge of conceptual truths does not lead towards the modal realm of metaphysics.

In spite of its everyday connotations, the term independence as republicans understand it is not a celebration of individualism or self-reliance but embodies an acknowledgement of the importance of personal and social relationships in people’s lives. It reflects our connectedness rather than separateness and is in this regard a relational ideal. Properly understood, independence is a useful concept in addressing a fundamental problem in social philosophy that has preoccupied theorists of relational autonomy, namely how to reconcile the idea of individual (...) human agency with the inevitable and necessary influence of other people, both directly and indirectly. I derive my account from the work of Mary Wollstonecraft and Catharine Macaulay, whose contributions have remained largely overlooked by current republican theorists. I have three purposes in this chapter. First, I set out the relational character of independence. Secondly, I outline a republican approach to the problem of structural social threats to agency. Finally, I hope to establish the basis for a fruitful dialogue between republicans and relational autonomy theorists on the requirements and dynamics of individual agency and freedom in oppressive social situations. I identify three distinctive features of the internal logic of freedom as independence that give it a relational character: it always locates the person within a community; there is a mediating role played by the notion of arbitrariness in connecting individual and collective perspectives; a causal relationship exists linking each person’s freedom as independence such that that the dependence of one class of persons jeopardizes the independence of the whole community.

Every quantum state can be represented as a probability distribution over the outcomes of an informationally complete measurement. But not all probability distributions correspond to quantum states. Quantum state space may thus be thought of as a restricted subset of all potentially available probabilities. A recent publication (Fuchs and Schack, arXiv:0906.2187v1, 2009) advocates such a representation using symmetric informationally complete (SIC) measurements. Building upon this work we study how this subset—quantum-state space—might be characterized. Our leading characteristic is that the inner (...) products of the probabilities are bounded, a simple condition with nontrivial consequences. To get quantum-state space something more detailed about the extreme points is needed. No definitive characterization is reached, but we see several new interesting features over those in Fuchs and Schack (arXiv:0906.2187v1, 2009), and all in conformity with quantum theory. (shrink)

To comprehend the special relativity genesis, one should unfold Einstein’s activities in quantum theory first . His victory upon Lorentz’s approach can only be understood in the wider context of a general programme of unification of classical mechanics and classical electrodynamics, with relativity and quantum theory being merely its subprogrammes. Because of the lack of quantum facets in Lorentz’s theory, Einstein’s programme, which seems to surpass the Lorentz’s one, was widely accepted as soon as quantum theory became a recognized part (...) of physics. A new approach to special relativity genesis enables to broaden the bothering “Trinity” group of its creators to include Gilbert N. Lewis. Notwithstanding that the links necessarily existing between all the 1905 papers were obscured by Einstein himself due to the reasons discussed below, Lewis revealed from the very beginning the connections between special relativity and quasi-corpuscular theory of light, as he punctuated: “The consequences which one of us obtained from a simple assumption as to the mass of a beam of light, and the fundamental conservation of mass, energy and momentum, Einstein has derived from the principle of relativity and the electromagnetic theory” (Lewis G.N.& Tolman R.C. “The Principle of Relativity and Non-Newtonian Mechanics”, Philosophical Magazine, 1908).

In Free Market Fairness, John Tomasi tries to show that ‘thick’ economic liberties, including the right to own productive property, are basic liberties. According to Tomasi, the policy-level consequences of protecting economic liberty as basic are essentially libertarian in character. I argue that if economic liberties are basic, just societies must guarantee their fair value to all citizens. And in order to secure the fair value of economic liberty, states must guarantee that citizens of roughly similar dispositions and talents are (...) roughly equally able to use their economic liberties to develop and pursue a conception of the good. This, I will argue, is a very demanding standard that requires aggressive taxation and redistribution. (shrink)

The developing body of empirical work on the "Gettier effect" indicates that, in general, the presence of a Gettier-type structure in a case makes participants less likely to attribute knowledge in that case. But is that a sufficient reason to diverge from a JTB theory of knowledge? I argue that considerations of good model selection, and worries about noise and overfitting, should lead us to consider that a live, open question. The Gettier effect is perhaps so transient, and so sensitive (...) to other, epistemologically-inappropriate factors, that it raises the question of whether it ought to be counted as something to include in our theories -- or as a piece of noise to be excluded from them.

The relations between ontology and information are many and fundamental, and they help us to understand the present gulf between (formal) ontology and (philosophical) Ontology: We can speak of respectively ontology-driven information and information-driven ontology as the focus on being informed vs. informed being. The question of whether these two (can) coincide is relevant to both fields, and in this article I elaborate on what needs to be addressed first of all to provide us with an answer: The form. This (...) core ontological concept rooting in Aristotelian metaphysics was central to philosophical ontology, in particular in Latin Scholasticism, when it was clearly put into relation with information as that which defines an entity. In this context, Dietrich of Freiberg synthesized this long debate in a way that matters not only to the philosophical effort of producing information-driven ontologies but also to the engineering constructs of ontology-driven information systems.

Introduction: The Faculty of Medicine, University of Moratuwa, established during the COVID-19 pandemic, was compelled to conduct the teaching activities online for the first intake of students until their first bar examination. Online learning is known to be linked to several health issues. This study aims to explore the academic performance and perceived health effects related to online learning in the Faculty of Medicine, Moratuwa. Methods: A descriptive cross-sectional study was conducted among all 104 first-intake students using an anonymous online (...) self-administered questionnaire to explore health effects and academic performance after ethical clearance. Results: Out of 104 students, 82 students responded (response rate=78.85%). Majority participated from home using their own laptop (74.4%) and personal Wi-Fi (69.5%) and spent 5-10 hours daily for online academic activities (72%). Majority complained of related physical (86.6%), and psychological (81.7%) health issues: eye problems (69.5%), headache (47.6%), backache (43.9%), stress (46.3%) and concentration difficulties (45.1%). The first bar examination was cleared by 84.1% with the majority (52.4%) obtaining classes. There was a statistically significant positive association (p< .05) between physical and psychological health concerns with the average screen-time spent on academic activities, but not with the academic performance. There was also no statistically significant association between screen-time and academic performance. Conclusions: Majority of students using online learning had related physical and psychological health issues which were positively associated with the screen-time though not with academic performance. Designing online activities with less screen time may be considered as a strategy to minimise health effects related to online learning. (shrink)

THE MAIN OBJECTIVES of the following discussions are, first, to show the logical inconsistency of Hegel’s theory of the necessity of private property and, second, to show its exegetical inconsistency with the most plausible and consistent interpretations of Hegel’s theory of the self and its relation to the state in Ethical Life. I begin with the latter objective, by distinguishing three basic conceptions of the self that can be gleaned from various passages in the Philosophy of Right. I suggest viable (...) connections between each of these three conceptions and three respective interpretations of what I call the Hegelian requirement, i.e., that the individual be able to identify his personal interests and values with those of the state [141, 147, 147r, 151, 155].1 This can be understood as the requirement that the individual be capable of transcending certain limits of individuality in the service of broader and more inclusive political goals. I argue that Hegel’s theory of Personality and the requirements of Ethical Life in the state commit him to a conception of the self as capable of achieving such selftranscendence through action, despite appearances to the contrary that suggest that self-transcendence is to be primarily achieved through acquisition of various kinds. I then try to demonstrate the logical inconsistency of Hegel’s theory of the necessity of private property. I argue that the fallacies inherent in his exposition of this theory can be explained by his presupposing a conception of the self which both is inadequate to meet the criteria of Hegel’s theories of Personality and Ethical Life and also, therefore, fails the Hegelian requirement.

I was quite excited when I first read Restall and Russell’s (2010) paper. For two reasons. First, because the paper provides rigorous formulations and formal proofs of implication barrier theses, namely “theses [which] deny that one can derive sentences of one type from sentences of another”. Second (and primarily), because the paper proves a general theorem, the Barrier Construction Theorem, which unifies implication barrier theses concerning four topics: generality, necessity, time, and normativity. After thinking about the paper, I am satisfied (...) with its treatment of the first three topics, namely generality, necessity, and time. But I am not satisfied with its treatment of normativity, so my comments are exclusively on that topic. (shrink)

According to one brand of 'externalism', cognitive theories should individuate mental content 'widely'--that is, partly in terms of environmental features. David Marr's theory of vision is often cited in support of this view. Many philosophers (most notably, Tyler Burge) regard it as a prime example of a fruitful cognitive theory that widely individuates the representations it posits. I argue that, contrary to popular belief, Marr's theory does not presuppose an externalist view of mental content.

I examine the role of the imagination (Einbildung) for Martin Heidegger after his Kant-reading of 1929. In 1929 he broadens the imagination to the openness of Dasein. But after 1930 Heidegger either disparages it as a representational faculty belonging to modernity; or further develops and clarifies its ontological broadening as the clearing or poiesis. If the hylo-morphic duality implied by Kantian imagination requires a prior unity, that underlying power unfolding beings in aletheic formations (poiesis) of being (the happening of being, (...) the opening of the world) would have to ultimately be in excess to any spontaneous power of subjectivity.

There are two inspirations for the theory presented. One is the Kantian idea that a free choice affects a deterministic sequence of events globally rather than just locally. The second is the Leibnizian idea that God chooses for actuality the possible world he deems best. But instead of God choosing, suppose free agents collectively do. Let actuality be an office which deterministic possible worlds are voted in and not of. In this way free choice can change things even if every (...) event is fully governed by deterministic laws: free choice substitutes one deterministic world for another. One way to look at the actual world on this theory is as a patchwork of segments of possible worlds. This gives the theory two advantages over familiar compatibilisms: it explains how the future is unsettled until chosen, and it allows that free choices are spontaneous. (shrink)

In this paper, I will explore how the work of Wallace Stevens constitutes a phenomenology that resonates strongly with that of William James. I will, first, explore two explicit references to James in the essays of Stevens that constitute a misrepresentation of a rather duplicitous quote from James’ personal letters. Second, I will consider Stevens’ little known lecture-turned-essay, “A Collect of Philosophy,” and the poem, “Large Red Man Reading,” as texts that are both about a conception of poetryphilosophy as well (...) as being performances of poetry-philosophy. Finally, I will compare James’ and Stevens’ thought on the imagination, highlighting both form and content and the poetic-philosophical union or blend that makes possible those similarities.

Team reasoning gives a simple, coherent, and rational explanation for human cooperative behavior. This paper investigates the robustness of team reasoning as an explanation for cooperative behavior, by assessing its long-run viability. We consider an evolutionary game theoretic model in which the population consists of team reasoners and ‘conventional’ individual reasoners. We find that changes in the ludic environment can affect evolutionary outcomes, and that in many circumstances, team reasoning may thrive, even under conditions that, at first glance, may seem (...) unfavorable. We also pursue several extensions that augment the basic account, and conclude that team reasoning is an evolutionarily viable mechanism with the potential to explain behavior in a range of human interactions.

This paper examines how the concepts of utility, impartiality, and universality worked together to form the foundation of Adam Smith's jurisprudence. It argues that the theory of utility consistent with contemporary rational choice theory is insufficient to account for Smith's use of utility. Smith's jurisprudence relies on the impartial spectator's sympathetic judgment over whether third parties are injured, and not individuals' expected utility associated with individuals' expected gains from rendering judgments over innocence or guilt.

It is argued that the origins of modern science can be revealed due to joint account of external and internal factors. The author tries to keep it in mind applying his scientific revolution model according to which the growth of knowledge consists in interaction, interpenetration and even unification of different scientific research programmes. Hence the Copernican Revolution as a matter of fact consisted in realization and elimination of the gap between the mathematical astronomy and Aristotelian qualitative physics in Ptolemaic cosmology. (...) Yet the very realization of the contradictions became possible because at the first stages European science was a result of Christian Weltanschaugung evolution with its gradual elimination of pagan components. Key words: modern European science, Christian Weltanschaugung. (shrink)

In this paper I explore the implications of the notion of hyperspace for scientific realism and the sort of theoretical activity represented by the attempt to arrive at a literal characterization of the noumenal realities that natural science, especially physics, investigates.

Only a very attenuated form of scientific realism, then, can reasonably (...) be endorsed by sober philosophy. (shrink)

Recursion or self-reference is a key feature of contemporary research and writing in semiotics. The paper begins by focusing on the role of recursion in poststructuralism. It is suggested that much of what passes for recursion in this field is in fact not recursive all the way down. After the paradoxical meaning of radical recursion is adumbrated, topology is employed to provide some examples. The properties of the Moebius strip prove helpful in bringing out the dialectical nature of radical recursion. (...) The Moebius is employed to explore the recursive interplay of terms that are classically regarded as binary opposites: identity and difference, object and subject, continuity and discontinuity, etc. To realize radical recursion in an even more concrete manner, a higher-dimensional counterpart of the Moebius strip is utilized, namely, the Klein bottle. The presentation concludes by enlisting phenomenological philosopher Maurice Merleau-Ponty’s concept of depth to interpret the Klein bottle’s extra dimension. (shrink)

Nancy Cartwright’s arguments in favor of the phenomenological laws and against the fundamental ones are discussed. I support and strengthen her criticism of the standard covering-law account but I am skeptical in respect to her radical conclusion that the laws of physics lie. Arguments in favor of the opposite stance are based on V.S. Stepin’s analysis of mature theory structure.

Special Relativity and the Early Quantum Theory were created within the same programme of statistical mechanics, thermodynamics and maxwellian electrodynamics reconciliation. I shall try to explain why classical mechanics and classical electrodynamics were “refuted” almost simultaneously or, in more suitable for the present congress terms, why did quantum revolution and the relativistic one both took place at the beginning of the 20-th century. I shall argue that quantum and relativistic revolutions were simultaneous since they had common origin - the clash (...) between the fundamental theories of the second half of the 19-th century that constituted the “body” of Classical Physics. The revolution’ s most dramatic point was Einstein’s 1905 photon paper that laid the foundations of both Special Relativity and Old Quantum Theory. Hence the dialectic of the old theories is crucial for theory change. Modern physics began with Einstein’s reconciliation of electrodynamics, mechanics and thermodynamics in 1905 and his unification of Special Relativity and Newtonian Theory of Gravity. Or, in more general social context: progressive scientific change can be described not in Weberian terms of zweckrational action forcing out all the other forms of action only but in terms of Habermas’s communicative rationality encouraging the establishment of mutual understanding between the various scientific communities also. Einstein’s programme constituted a progressive step in respect to its rivals not because it could explain more “facts” or was more “mathematical”. It was high than its rivals because it constituted a basis of communication and interpenetration between three main paradigms of 19-th century physics. Of course in the long run it resulted in empirical successes. Key words: Einstein, scientific revolution, communicative rationality. (shrink)

What were the reasons of the Copernican Revolution ? How did modern science (created by a bunch of ambitious intellectuals) manage to force out the old one created by Aristotle and Ptolemy, rooted in millennial traditions and strongly supported by the Church? What deep internal causes and strong social movements took part in the genesis, development and victory of modern science? The author comes to a new picture of Copernican Revolution on the basis of the elaborated model of scientific revolutions (...) that takes into account some recent advances in philosophy, sociology and history of science. The model was initially invented to describe Einstein’s Revolution of the XX century beginning. The model considers the growth of knowledge as interaction, interpenetration and unification of the research programmes, springing out of different cultural traditions. Thus, Copernican Revolution appears as a result of revealation and (partial) resolution of the dualism , of the gap between Ptolemy’s mathematical astronomy and Aristotelian qualitative physics. The works of Copernicus, Galileo, Kepler and Newton were all the stages of mathematics descendance from skies to earth and reciprocal extrapolation of earth physics on skies. The model elaborated enables to reassess the role of some social factors crucial for the scientific revolution. It is argued that initially modern science was a result of the development of Christian Weltanschaugung . Later the main support came from the absolute monarchies. In the long run the creators of modern science appeared to be the “apparatchics” of the “regime of truth” built-in state machine. Natural science became a part of ideological state apparatus providing not only scientific education but the internalization of values crucial for the functioning of state. -/- . (shrink)

What are the reasons of the second scientific revolution that happened at the beginning of the XX century? Why did the new physics supersede the old one? The author tries to answer the subtle questions with a help of the epistemological model of scientific revolutions that takes into account some recent advances in philosophy, sociology and history of science. According to the model, Einstein’s Revolution took place due to resolution of deep contradictions between the basic classical research traditions: Newtonian mechanics, (...) maxwellian electrodynamics, thermodynamics and statistical mechanics. As a result, two new research programmes – relativistic and quantum- had been constructed. It was the interaction between them that formed the interdisciplinary context of Einstein’s Revolution.

Peter van Inwagen's Direct Argument (DA) purports to establish the incompatibility of determinism and moral responsibility, without appealing to the notion of avoidability, a notion on whose analysis compatibilists and incompatibilists disagree. Van Inwagen intended DA to refute compatibilism, or at least to shift the burden of proof onto the compatibilist. In this paper, we offer a critical assessment of DA. We examine a variety of objections to DA due to John Fischer and Mark Ravizza, Ishtiyaque Haji, Seth Shabo, Michael (...) McKenna, and David Widerker. We divide these objections into those based on dialectical considerations (section 1), and objections in the form of counterexamples to a central principle which the Direct Argument employs (sec 2). The conclusion we reach is that the proponent of DA can deal plausibly with these objections, thus establishing DA as a powerful argument in favor of incompatibilism. (shrink)
