Business ethics’ theories have come under a lot of criticism lately. The problem has been the lack of a philosophical base or the inadequate implementation of it. We are trying to solve this problem by examining the roots of ethics and then applying it to the business environment. The root that has been undeservedly overlooked has been the concept of free will, the oldest philosophical problem on which every ethics theory lies. We have chosen two theories that we think would (...) be the best base for business ethics. We will shortly present the others. Since free will presents the core of business ethics, business ethicists must first agree on which theory to implement. Aristotle’s and Aquinas’ theory of free will best amplify the core of economic theory, because it gives reason a central and most important role in the theory. The concept of free will is mainly philosophical as is business ethics so the article follows this tradition, but we tried to give business examples where possible. We do not give a final conclusion because it should be reached by debate and mutual agreement between business ethicists. (shrink)

The decline of empirical research on ethical decision-making based on ethical theories might imply a tacit consensus has been reached. However, the exclusion of virtue ethics, one of the three main normative ethical theories, from this stream of literature calls this potential consensus into question. This article investigates the role of all three normative ethical theories—deontology, utilitarianism and virtue ethics—in ethical decision-making of corporate executives. It uses virtue ethics as a dependent variable thus studying the interconnectivity of all three normative (...) ethical theories in specific circumstances. We find that managers use different ethical theories in different circumstances (business vs. private life, formal vs informal ethical leadership, etc.). A predictive model of ethical decision-making, however, cannot be established. We also find that only a limited number of variables influence the choice of ethical theory, which leans business ethics towards postmodern management paradigm. We suggest that moral pragmatism could provide the answer to ethical decision-making. (shrink)

In this book, Matej Kohar demonstrates how the new mechanistic account of explanation can be used to support a non-representationalist view of explanations in cognitive neuroscience, and therefore can bring new conceptual tools to the non-representationalist arsenal. Kohar focuses on the explanatory relevance of representational content in constitutive mechanistic explanations typical in cognitive neuroscience. The work significantly contributes to two areas of literature: 1) the debate between representationalism and non-representationalism, and 2) the literature on mechanistic explanation. Kohar begins with (...) an introduction to the mechanistic theory of explanation, focusing on the analysis of mechanistic constitution as the basis of explanatory relevance in constitutive mechanistic explanation. He argues that any viable analysis of representational contents implies that content is not constitutively relevant to cognitive phenomena. The author also addresses objections against his argument and concludes with an examination of the consequences of his account for both traditional cognitive neuroscience and non-representationalist alternatives. This book is of interest to readers in philosophy of mind, cognitive science and neuroscience. (shrink)

Though historically important, the notion of tacit consent plays little role in contemporary discussions of political legitimacy. The idea, in fact, is often dismissed as obviously implausible. The ambition of this paper is to challenge this assumption and show that tacit consent can become a key ingredient in a theory of legitimacy. Instead of defining tacit consent through residence (where, according to John Locke or Plato's Socrates, staying in the country amounts to tacitly consenting to its system of rule), the (...) paper explores a different strategy, delimiting tacit consent as an absence of active dissent. The basic idea starts from the fact that widespread anti-government protests and demonstrations always carry a potent delegitimating force. Political legitimacy is therefore never permanent and unchangeable, regardless of the nature of the regime, and can be undermined at all times by active dissent from the population. Having established the relationship between dissent and delegitimation of political power, even the inverted, stronger claim is defended: the absence of active dissent (i.e., tacit consent) can, under certain circumstances, serve to legitimize political power. The paper sets up and defends several conditions that need to be met for the right normative mandate to be created by the population tacitly accepting the existing power arrangements. If those are fulfilled (especially when full freedom of expression and information is granted), tacit consent can become a vital element of political legitimacy. (shrink)

The popularity of conspiracy theories poses a clear challenge for contemporary liberal democracies. Conspiracy theories undermine rational debate, spread dangerous falsehoods and threaten social cohesion. However, any possible public policy response, which would try to contain their spread, needs to respect the liberal commitment to protect pluralism and free speech. A successful justification of such a policy must therefore: 1) clearly identify the problematic class of conspiracy theories; and 2) clarify the grounds on which the state is justified in acting (...) against them. This article argues that the prevailing epistemic approaches to conspiracy theorizing cannot fulfil these criteria. Defining conspiracy theories by their flaws in reasoning, questionable coherence or factual mistakes can neither sharply distinguish problematic conspiracy theories from other, non-problematic worldviews nor justify state action. Thus, we propose to understand conspiracy theories through their ethical unreasonableness. We hold that containment of conspiracy theories is justifiable insofar as they undermine the liberal-democratic ideals of mutual respect, freedom and equality. We then show that such ‘ethical’ criteria for conspiracy theories can be sufficiently robust and clear-cut so that they can serve as a useful guide for public policy. (shrink)

In this paper, I show how normative inferentialism could be used to explain several phenomena related to natural languages. First, I show how the distinction between the inferential potential and the inferential significance fits the standard distinction between the meaning of a sentence and the content of an utterance. Second, I show how the distinction could be used to explain ambiguity and free pragmatic enrichment from the perspective of normative inferentialism. The aim of this paper is to establish theoretical foundations (...) that enable normative inferentialism to enter the discussions within the literalism-contextualism debate. As I argue, the biggest advantage of inferentialism is that it provides one general framework for the representation of meaning/content that naturally incorporates contextual information and so it can be used to represent meanings of various types of context-dependent sentences.

The aim of this paper is to establish a specific view of linguistic understanding based on the framework of normative inferentialism. Normative inferentialism is presented as an overspecification (rich) account of meaning—the meaning of a sentence is understood as a cluster of context‐dependent contents. The standard psychological mechanism responsible for reaching understanding of an utterance depends on the ability to eliminate contextually irrelevant aspects/parts of meaning. The advantages of the view are that the mechanism can (a) explain a wide range (...) of linguistic phenomena including polysemy, homonymy, and conversational implicatures, and (b) explain partial understanding of an utterance.

Tattoos are widely regarded as morally neutral, and the decision to have them as carrying no ethical implications. The aim of this paper is to question this assumption. I argue that decisions to have tattoos involve risks that are not merely prudential—they are normative. The argument starts with a thesis that the power we presently have over our lives is constrained by the need to respect our future selves. If we make a discretionary choice that disregards our future interests and (...) preferences, then, under certain circumstances, we can be morally to blame. I argue that certain decisions to get tattoos fit this description. Therefore, getting some tattoos makes us blameworthy. (shrink)

For more than a decade now a profound rule-of-law crisis has gripped the European Union, and while the fight for the rule of law has topped not only the academic but also the judicial and political agenda, the results have been disappointingly meagre. This article argues that the main reason for that should be sought in a political strategic move of justifying the assaults on the rule of law by resorting to an “illiberal democracy.” This premeditated political narrative shift has (...) unleashed onto the political sphere and onto public discourse at large comprehensive doctrines which had hitherto been left dormant thanks to an overlapping consensus on the rule of law as a central building block of the political conception of justice à la Rawls. Once this overlapping consensus was broken, the rule of law itself lost its neutral character as a referee on the right among the many conceptions of the good, itself becoming part of the highly politicized power play for dominance among irreconcilable—liberal and illiberal—comprehensive doctrines. The overlapping consensus in the EU is thus broken, but there are no conceptual reasons inherent to the rule of law itself for which it could not be rebuilt in the future. (shrink)

Opponents of the new mechanistic account of scientific explanation argue that the new mechanists are committed to a ‘More Details Are Better’ claim: adding details about the mechanism always improves an explanation. Due to this commitment, the mechanistic account cannot be descriptively adequate as actual scientific explanations usually leave out details about the mechanism. In reply to this objection, defenders of the new mechanistic account have highlighted that only adding relevant mechanistic details improves an explanation and that relevance is to (...) be determined relative to the phenomenon-to-be-explained. Craver and Kaplan (B J Philos Sci 71:287–319, 2020) provide a thorough reply along these lines specifying that the phenomena at issue are contrasts. In this paper, we will discuss Craver and Kaplan’s reply. We will argue that it needs to be modified in order to avoid three problems, i.e., what we will call the Odd Ontology Problem, the Multiplication of Mechanisms Problem, and the Ontic Completeness Problem. However, even this modification is confronted with two challenges: First, it remains unclear how explanatory relevance is to be determined for contrastive explananda within the mechanistic framework. Second, it remains to be shown as to how the new mechanistic account can avoid what we will call the ‘Vertical More Details are Better’ objection. We will provide answers to both challenges.

The paper examines the complex relation between anti-democratic forces (“the extremists”) and the broader liberal-democratic institutional environment. The task of containing extremists is analysed both from a theoretical standpoint and in terms of its practical feasibility. I argue that the realities of political communication and the character of political argumentation make containing extremism in practice a much more daunting proposition than is usually understood in the literature. Insights from political philosophy, political science and communication theory are brought together to press (...) these points. As a result, extremists often cannot be stopped from running for office even if the state possesses tools to ban extremist parties. Moreover, once extremist politicians become members of legislative bodies, several democratic and procedural considerations start to apply to them so that it becomes difficult to limit their influence. Their elevated status (given their positions as legitimate representatives of the people, together with the increased media and argumentative platform they gain) complicates attempts at stopping the proliferation of their views. The last part of the paper briefly sketches possible (remnants of) a strategy of containment, arguing that only a combination of informal sanctions can be (partially) successful, including deplatforming, refusal to engage with them, and a pariah status in the legislative assembly.

A theory is presented in which a field depends not only on spacetime coordinates xμ, but also on a Lorentz-invariant parameter τ. Such a theory is conceptually and technically simple and manifestly covariant at every step. The generator of evolution and the generator of spacetime translations and Lorentz transformations are obtained in a straightforward way. In the quantized theory the Heisenberg equation of motion is written in a covariant form and is equivalent to the field equation. The equal τ commutator (...) between the field and its canonically conjugate momentum is just proportional to the spacetime δ function. Finally comparison with the conventional field theory is done, and it is found that the expectation value of the momentum operator in the on shell states is the same. (shrink)

Continuously from the 1940s, Michael Polanyi comments on topics that have resonated later since the 1960s in the works of his fellow theorists of science, philosophers of natural sciences, and epistemologists. First part of this article provides a brief reconstruction of Polanyi’s concept of „personal knowledge“ which focuses mainly on the interconnection of the individual level of scientific research with its social dimension. My aim is to evaluate the potential of this concept for the interpretation of research fields where sciences (...) are in close contact with other disciplines. I am convinced that Polanyi’s original approach to the problem of reality should be read as an advocacy of diversity of thought. In my interpretation, Polanyi carries out some form of philosophical therapy of science and its self-concept, which, like the whole of Western society, has undergone dramatic changes over the last century.

In his book Moralna spoznaja Baccarini argues that, with respect to the individual reasoning about morality, the method of reflective equilibrium is the appropriate method of moral reasoning. The starting point of my argument is Baccarini’s refutation of Hare’s view. As I see it, one of Baccarini’s central arguments against Hare consists in claiming that Hare’s approach to the amoralist objection weakens the deductive model of moral reasoning. I argue that the amoralist objection also posses a threat to the method (...) of reflective equilibrium. At the end of the paper, I consider another view of moral reasoning which, in my view, is better suited to deal with the amoralist objection. (shrink)

Prolonged trunk flexion is known to affect passive and active stabilization of the trunk. Previous studies have evaluated changes in spinal range of motion, muscle activity and reflex behavior induced by prolonged trunk flexion, whereas the effect on sitting postural control is vastly underexplored. In this study, we compared the effects of supported and unsupported intermittent trunk flexion on center of pressure motion during sitting on an unstable seat. Participants were exposed to 1-h intermittent trunk flexion and CoP root mean (...) square distance, velocity and frequency before and after the exposure were assessed. Contrary to our hypothesis, there were no main effects of exposure, no main effects of condition, and no interaction between exposure and condition. Our results indicate that prolonged intermittent flexion does not induce any changes in CoP motion during a seated balance task, regardless of the presence of a trunk support during prolonged intermittent flexion. This suggests a successful compensation of decreased passive stiffness by increased reflex activity. (shrink)

Prema hjumovskoj teoriji motivacije, motivacijski se proces sastoji od dva međusobno nezavisna mentalna stanja , što znači da subjekt ne može biti u potpunosti motiviran na djelovanje ako mu jedno od tih stanja nedostaje.

This paper is guided by two research hypotheses: (1) In contemporary public discourse, many of the most urgent political problems are predominantly framed and understood in moral terms; (2) this shift in framing has far-reaching consequences, impeding our understanding of the underlying problems and their eventual solution. The two hypotheses are demonstrated using multiple examples, with the fight against climate change serving as the main case study. The moral framing (thinking in terms of individual actions, duties and obligations, blame and (...) personal responsibility) is shown to crowd out political considerations (focused on institutions and policy), even when such moral considerations are either out of place or immaterial. Consequently, individual actions and responsibility are shown to be overemphasized in contemporary public discourse to such an extent that the viable political solutions are often discounted or overlooked. The context of the argument offered here is provided by the realism-moralism debate on the distinction between morality and politics. The ambition of the paper is to show that, regardless of their possible deeper distinction (the “distinctively political normativity”), there is a strong pragmatic case for carefully distinguishing between ethical and political theorizing. Morality and politics provide different frames, distinct interpretive frameworks that consequently give rise to contrasting solutions. Therefore, they need to be kept apart. (shrink)

Medieval interpretations of hylomorphism, in which substances are conceived as metaphysical composites of prime matter and substantial form, are receiving attention in contemporary philosophy. It has even been suggested that a recovery of Aquinas's conception of prime matter as a ‘pure potentiality’, lacking any actuality apart from substantial form, may be expedient in hylomorphic interpretations of quantum mechanics. In this paper, we consider a recent hylomorphic interpretation of non-relativistic quantum mechanics, the theory of Cosmic Hylomorphism, which does not explicitly invoke (...) any notion of prime matter in its original formulation. We argue that prime matter does in fact play a role in constituting and individuating particles in this theory. However, we demonstrate that the notion of prime matter which features in the extended version of Cosmic Hylomorphism that we propose here is distinct from Aquinas's conception of prime matter, inasmuch as it has discrete metaphysical parts.

Ever since the publication of Scanlon’s Promises and Practices and What We Owe to Each Other, expectations have become an important topic within discussions on promises. However, confining the role of expectations to promises does not do justice to their importance in creating obligations more generally. This paper argues that expectations are one of the major sources of obligations created within our personal relationships. What we owe to our friends, partners, or siblings very often follows neither from the duties associated (...) with the given role, nor from our explicit promises, commitments, declarations, or consents. The obligations that our close relationships create often arise from a shared understanding of those relationships—and subsequent mutually acknowledged expectations. (shrink)

The contribution of the body to cognition and control in natural and artificial agents is increasingly described as “off-loading computation from the brain to the body”, where the body is said to perform “morphological computation”. Our investigation of four characteristic cases of morphological computation in animals and robots shows that the ‘off-loading’ perspective is misleading. Actually, the contribution of body morphology to cognition and control is rarely computational, in any useful sense of the word. We thus distinguish (1) morphology that (...) facilitates control, (2) morphology that facilitates perception and the rare cases of (3) morphological computation proper, such as ‘reservoir computing.’ where the body is actually used for computation. This result contributes to the understanding of the relation between embodiment and computation: The question for robot design and cognitive science is not whether computation is offloaded to the body, but to what extent the body facilitates cognition and control – how it contributes to the overall ‘orchestration’ of intelligent behaviour.

After a brief discussion of the terms determinism and free will, the paper sets out to compare some recent philosophical approaches to the problem of free will with a theological anthropology account of the notion. It aims to defend the claim, that even though different kind of questions are asked on both sides, they tackle similar issues and a complementary approach is needed. Recent philosophy considers the problem mostly from the standpoint of logic, naturalist evolutionary ontology and cognitive science. In (...) the Christian theological tradition, the idea of free will has been discussed mostly from the perspective of the problem of sin and grace, thus on the grounds of soteriology, hamartiology and theological ethics. The paper shows similarities between the approaches, mainly between the problem of physical determinism and theological determinism and also divine foreknowledge. (shrink)

In spite of the iron curtain looming large between western academics and their (often politically persecuted and institutionally detached) colleagues in the eastern bloc, some intellectual developments bear striking similarities. This paper analyses one of them: the conception of human rights by Ladislav Hejdánek as opposed to Kantian constructivism, which was developed in the “west” by John Rawls and others. Both Rawls and Hejdánek, who was one of the philosophical heavyweights of Czech dissent, are moved by very similar concerns: the (...) need to ground objective values without falling into utilitarianism or some (other) form of naïve ethical objectivism. They view political values as constructed and yet objective, not given but still sound. Given the immense difference in their professional position and philosophical style, this indicates a truly interesting case of a unity of concern bridging the east and the west, even under very unfavorable political conditions.

Contemporary defenses of the doctrine of double effect are mainly focused on avoiding the absurdity charge raised by Judith Thomson (). There are two strategies proposed in the literature for refuting Thomson's argument.

Thomson's argument reveals that the proponents of the DDE can at best (...) provide a partial defense of the claim that intentions can be relevant to permissibility. (shrink)

This paper examines a well-known non-identity case of a mother who chooses to conceive a blind child instead of a sighted one.

This paper proposes a somewhat middle approach. It is argued that the conclusion of the non-identity argument is not necessarily in conflict (...) with our intuitive response to this case. (shrink)

In the corpus of phenomenological philosophy (as far as it is influenced by the works of Jacob von Uexküll and the debate of phenomenologists with philosophical anthropologists such as E. Cassirer, F. J. J. Buytendijk, and A. Portmann), we find the allegation that one of the fundamental differences between human and non-human animals is that while the non-human animal has a species-specific umwelt, humans have access to (a certain idea of) welt. In this sense, Heidegger speaks of the animal as (...) a being “poor-in-world” in contrast to man as a “world-making” being. Similarly, Merleau-Ponty states that language helps a human person step out of her umwelt into the idea of welt. In the present study, I proceed from the critical reflection of this umwelt–welt distinction, emphasizing the question of the status of this “world.” For a better understanding of this problem, I illustrate it by the example of sign language acquisition by congenitally deafblind people, using phenomenological analysis of intercorporeality and associated phenomena in combination with “dialogical epistemology” as an interpretive framework. Claude Romano’s thesis of “evential hermeneutics” can illuminate this situation, as it explains the vital role various events play in establishing the world through our experience. From this point of view, the “world” plays a role not as a sum of objects in a play of objective causes, but rather it is a transcendental field from which events arise. (shrink)

ABSTRACT: A traditional objection to inferentialism states that not all inferences can be meaning-constitutive and therefore inferentialism has to comprise an analytic-synthetic distinction. As a response, Peregrin argues that meaning is a matter of inferential rules and only the subset of all the valid inferences for which there is a widely shared corrective behaviour corresponds to rules and so determines meaning. Unfortunately, Peregrin does not discuss what counts as “widely shared”. In the paper, I argue for an empirical plausibility of (...) Peregrin’s proposal. The aim of the paper is to show that we can find examples of meaning-constitutive linguistic action, which sustain Peregrin’s response. The idea is supported by examples of meaning modulation. If Peregrin is right, then we should be able to find specific meaning modulations in which a new meaning is publicly available and modulated in such a way that it has a potential to be widely shared. I believe that binding modulations – a specific type of meaning modulations – satisfy this condition. (shrink)

Práce se zabývá filosofickou analýzou vědeckého výzkumu, kterou v polovině minulého století provedla botanička Agnes Arberová.

We consider a theory in which spacetime is a 4-dimensional manifold V4 embedded in an N-dimensional space VN. The dynamics is given by a first-order action which is a straightforward generalization of the well-known Nambu-Gotto string action. Instead of the latter action we then consider an equivalent action, a generalization of the Howe-Tucker action, which is a functional of the (extrinsic) embedding variables ηa(x) and of the (intrinsic) induced metric gυv (x) on V4. In the quantized theory we can define (...) an effective action by means of the Feynman path integral in which we functionally integrate over the embedding variables. What remains is functionally dependent solely on the induced metric. It is well known that the effective action so obtained contains the Ricci scalar R and its higher orders. But due to our special choice of a quantity, the so-called “matter” density ω(η) in VN entering the original first-order action, it turns out that the effective action contains also the source term. The latter is in general that of a p-dimensional membrane (p-brane). In particular we consider the case of bosonic point particles. Finally we discuss and clarify certain interpretational aspects of quantum mechanics from the viewpoint of our embedding model. (shrink)

The relativistic quantum mechanics with Lorentz-invariant evolution parameter and indefinite mass is a very elegant theory. But it cannot be derived by quantizing the usual classical relativity in which there is the mass-shell constraint. In this paper the classical theory is modified so that it remains Lorentz invariant, but the constraint disappears; mass is no longer fixed—it is an arbitrary constant of motion. The quantization of this unconstrained theory gives the relativistic quantum mechanics in which wave functions are localized and (...) normalized in spacetime. Though many authors have published good works in support for such a localization in time, the latter has been generally considered as problematic. Here I show that wave packets restricted to a finite region of spacetime are not a nuisance, but just the contrary. They have the physical interpretation in the fact that an observer perceives a world line event by event, as his experience of “now” proceeds in spacetime. Quantum mechanically this means that at a certain value of the evolution parameter τ the event is most probably to occur within the spacetime region around {ie1005-1} occupied by the wave packet; at later value of τ the position {ie1005-2}—and hence the time coordinate t—of the wave packet is changed. This is closely related to the interpretation of quantum mechanics in general. (shrink)

Engineers fine-tune the design of robot bodies for control purposes, however, a methodology or set of tools is largely absent, and optimization of morphology (shape, material properties of robot bodies, etc.) is lagging behind the development of controllers. This has become even more prominent with the advent of compliant, deformable or ”soft” bodies. These carry substantial potential regarding their exploitation for control—sometimes referred to as ”morphological computation”. In this article, we briefly review different notions of computation by physical systems and (...) propose the dynamical systems framework as the most useful in the context of describing and eventually designing the interactions of controllers and bodies. Then, we look at the pros and cons of simple vs. complex bodies, critically reviewing the attractive notion of ”soft” bodies automatically taking over control tasks. We address another key dimension of the design space—whether model-based control should be used and to what extent it is feasible to develop faithful models for different morphologies. (shrink)

Recent work on compositional distributional models shows that bialgebras over finite dimensional vector spaces can be applied to treat generalised quantifiersGeneralised quantifiers for natural language.

We show that this category is a concrete instantiation of the (...) compositional distributional model.

The article provides an analysis of Paul and Patricia Churchland’s eliminative materialism. I will distinguish two lines of argument in their eliminativism: one seeking to eliminate folk psychology and the second criticising Jerry Fodor’s language of thought hypothesis. Then I will closely examine the second line of argument, and show that it represents the main motive of Churchland’s work since the end of 1980s and demonstrate why the success of the argument against the language of thought hypothesis does not constitute (...) a reason for the elimination of folk psychology. Finally, I will examine the consequences of this approach for the role of folk psychology in the study of mind and show that the weakened eliminativist position still fulfils the original aim of Churchland’s program.

The criterion of naturalness represents David Lewis’s attempt to answer some of the sceptical arguments in semantics by comparing the naturalness of meaning candidates. Recently, the criterion has been challenged by a new sceptical argument. Williams argues that the criterion cannot rule out the candidates which are not permuted versions of an intended interpretation. He presents such a candidate – the arithmetical interpretation semantics by comparing the naturalness of meaning candidates. Recently, the criterion has been challenged by a new sceptical (...) argument. Williams argues that the criterion cannot rule out the candidates which are not permuted versions of an intended interpretation. He presents such a candidate – the arithmetical interpretation, and he argues that it opens up the possibility of Pythagorean worlds, i.e. the worlds similar to ours in which the arithmetical interpretation is the best candidate for a semantic theory. The aim of this paper is a) to reconsider the general conditions for the applicability of Lewis’s criterion of naturalness and b) to show that Williams’s new sceptical challenge is based on a problematic assumption that the arithmetical interpretation is independent of fundamental properties and relations. As I show, if the criterion of naturalness is applied properly, it can respond even to the new sceptical challenge. (shrink)
