This study evaluated the effects of an exergame program combined with traditional tennis training on autonomic regulation, tennis technique, gross motor skills, clinical reaction time, and cognitive inhibitory control in children. Sixty-three children were randomized into four groups and compared at baseline, 6-month immediately post intervention and at 1-year follow-up post intervention. At 6-month post intervention the combined exergame and regular training sessions revealed: higher breathing frequency, heart rate and lower skin conductance levels during exergaming; additional benefits in the point (...) of contact and kinetic chain elements of the tennis forehand and backhand technique ; negative impact on the shot preparation and the follow-through elements ; higher ball skills ; higher percentages of clinical reaction time improvement and cognitive inhibitory control improvement in both congruent and incongruent trials. The 1-year follow-up test showed no differences in the tennis technique, clinical reaction time and cognitive inhibitory control improvement between groups with the same number of trainings per week. The findings support exergaming as an additional training tool, aimed to improve important cognitive-motor tennis skills by adding dynamics to the standardized training process. Caution should be placed to planning this training, e.g., in a mesocycle, since exergaming might decrease the improvement of specific tennis technique parts of the trainees.. (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 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)

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)

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)

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)

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.

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)

I argue that Robert Nozick, in his well-known book “Anarchy, State, Utopia”, is working with Locke’s notion of the natural right to property merely instrumentally. I use the term “instrumentally” in the sense that the pieces of the source are not used within the context of the original work but are used atomically to support one’s argument or theory. Instrumental use of Locke’s theory causes incoherence in his theory. This paper introduces the incoherence in the question and explains how this (...) incoherency is inherent to Nozick’s interpretation and usage of Lockean Proviso. (shrink)

Starting from the geometric calculus based on Clifford algebra, the idea that physical quantities are Clifford aggregates (“polyvectors”) is explored. A generalized point particle action (“polyvector action”) is proposed. It is shown that the polyvector action, because of the presence of a scalar (more precisely a pseudoscalar) variable, can be reduced to the well known, unconstrained, Stueckelberg action which involves an invariant evolution parameter. It is pointed out that, starting from a different direction, DeWitt and Rovelli postulated the existence of (...) a clock variable attached to particles which serve as a reference system for identification of spacetime points. The action they postulated is equivalent to the polyvector action. Relativistic dynamics (with an invariant evolution parameter) is thus shown to be based on even stronger theoretical and conceptual foundations than usually believed. (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 theory of unconstrained membranes of arbitrary dimension is presented. Their relativistic dynamics is described by an action which is a generalization of the Stueckelberg point-particle action. In the quantum version of the theory, the evolution of a membrane's state is governed by the relativistic Schrödinger equation. Particular stationary solutions correspond to the conventional, constrained membranes. Contrary to the usual practice, our spacetime is identified, not with the embedding space (which brings the problem of compactification), but with a membrane of (...) dimension 4 or higher. A 4-membrane is thus assumed to represent spacetime. The Einstein-Hilbert action emerges as an effective action after functionally integrating out the membrane's embedding functions. (shrink)

The arguments by Pandres that the double valued spherical harmonics provide a basis for the irreducible spinor representation of the three dimensional rotation group are further developed and justified. The usual arguments against the inadmissibility of such functions, concerning hermiticity, orthogonality, behaviour under rotations, etc., are all shown to be related to the unsuitable choice of functions representing the states with opposite projections of angular momentum. By a correct choice of functions and definition of inner product those difficulties do not (...) occur. And yet the orbital angular momentum in the ordinary configuration space can have integer eigenvalues only, for the reason which have roots in the nature of quantum mechanics in such space. The situation is different in the velocity space of the rigid particle, whose action contains a term with the extrinsic curvature. (shrink)

Dewey, kućni prijatelj i politički istomišljenik njegova oca, inspirirao je Rortyja od malih nogu, ostajući uzor kojemu bi se na svakom spoznajnom raskrižju uvijek vraćao. Njegov pragmatizam poslužio mu je u odbacivanju filozofskih, društvenih i kulturnih dogmi, a njegov demokratizam poticao na oduševljenje američkim patriotizmom, koji je obojici važio za esencijalnu komponentu građanstva, što su im kritičari predbacivali kao crtu naiviteta. No i ta se »naivistička« Deweyjeva načela Rortyjevog zagovaranja slobode pravednije jednakosti, temelje na baštini njegove prosvjetiteljski katarzične socijalne etike, (...) kojom se je Rorty, s velikim povjerenjem u društveno dobro, izvlačio iz kreativnog nihilizma svog ironičnog »antiizma«.Dewey inspired Rorty in the first place as his father’s friend and political mate. Whenever the younger man was at some kind of a cognitive crossroads Dewey would act as his philosophical anchor. Dewey’s pragmatism and democratism helped him in casting off philosophical, social and cultural dogmas, at the same time encouraging him to turn towards the enthusiasm of America’s patriotism that was for both of them an essential component of citizenry. Their critics described this component and the principles of Dewey’s and Rorty’s social ethics as some kind of naïveté. Rorty followed the so-called naïveté of Dewey pleading for liberty as some kind of fundamental fairer equality. Rorty applied Dewey’s heritage of enlightened cathartic social ethics using it with great belief in public good, and as a means of saving himself from the creative nihilism of his own ironic “antiism”.

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)

Scientific knowledge production is a domain of human excellence, but recently this position became progressively challenged by machine intelligence. Some human tasks will be conquered sooner; others, which include design, may still require human intuition. Would the automated knowledge production truly challenge the human, or is one just an extension – a prosthetic – of the other? What could be the place of art in such environment? Mess and messy scientific models have the potential to provide paradigm shifts in molecular (...) modelling, cancer research and systems biology where not only living humans but also machine learning algorithms craft knowledge. Together with art they have the potential for different reading and re-framing, which are the qualities scientists are looking for when engaging works of art within their molecular modelling process. In my opinion, these are the same qualities scientists are also looking for in the outputs of machine learning and computational chemistry modelling. (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)

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.

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.

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)

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)

These carry substantial potential regarding their exploitation for control – sometimes referred to as "mor- phological computation" in the sense of offloading computation (...) needed for control to the body. Here, we will argue in favor of a dynamical systems rather than com- putational perspective on the problem. Then, we will 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 will 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. ----- This paper was also published in the 2014 AISB proceedings http://aisb50.org/representation-of-reality-humans-animals-and-machines/ - http://doc.gold.ac.uk/aisb50/.

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.

The relativistic theory of unconstrained p-dimensional membranes (p-branes) is further developed and then applied to the embedding model of induced gravity. Space-time is considered as a 4-dimensional unconstrained membrane evolving in an N-dimensional embedding space. The parameter of evolution or the evolution time τ is a distinct concept from the coordinate time t=x0. Quantization of the theory is also discussed. A covariant functional Schrödinger equation has a solution for the wave functional such that it is sharply localized in a certain (...) subspace P of space-time, and much less sharply localized (though still localized) outside P. With the passage of evolution the region P moves forward in space-time. Such a solution we interpret as incorporating two seemingly contradictory observations: (i) experiments clearly indicate that space-time is a continuum in which events are existing; (ii) not the whole 4-dimensional space-time, but only a 3-dimensional section which moves forward in time, is accessible to our immediate experience. The notorious problem of time is thus resolved in our approach to quantum gravity. Finally we include sources into our unconstrained embedding model. (shrink)

A new theory is considered according to which extended objects in n-dimensional space are described in terms of multivector coordinates which are interpreted as generalizing the concept of center of mass coordinates. While the usual center of mass is a point, by generalizing the latter concept, we associate with every extended object a set of r-loops, r=0,1,...,n−1, enclosing oriented (r+1)-dimensional surfaces represented by Clifford numbers called (r+1)-vectors or multivectors. Superpositions of multivectors are called polyvectors or Clifford aggregates and they are (...) elements of Clifford algebra. The set of all possible polyvectors forms a manifold, called C-space. We assume that the arena in which physics takes place is in fact not Minkowski space, but C-space. This has many far reaching physical implications, some of which are discussed in this paper. The most notable is the finding that although we start from the constrained relativity in C-space we arrive at the unconstrained Stueckelberg relativistic dynamics in Minkowski space which is a subspace of C-space.

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 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.

This article examines the relationship between the concept of sovereignty and the process of European integration. It is argued that the nature of this relationship has been both mutually informative and transformative. As a particular understanding of sovereignty has influenced and determined the perception of European integration, i.e., its conceptualization, so the process of European integration has reflected back on sovereignty and entailed its rethinking. This poses a particular challenge for legal theorists: how to pin down the meaning of sovereignty (...) and European integration so as to put both in the best conceptual and normative light. The article begins by looking at the traditional perspective on sovereignty and how this has been challenged by European integration. The focus then shifts from sovereignty to European integration in order to examine how different perspectives on sovereignty, when used as an epistemic lens for understanding the process of European integration, have produced uneven conceptions of this integration. Finally, the article concludes by making a choice between the various conceptions of sovereignty and European integration. It is argued that the best conception of European integration is offered by the constitutional form of a union founded on pluralist sovereignty. (shrink)

In this paper, I discuss Quine’s views on language sharing and linguistic communities. It is sometimes explicitly and often implicitly taken for granted that Quine believes that speakers can form communities in which they share a language. The aim of the paper is to show that this is a misinterpretation and, on the contrary, Quine is closer to linguistic individualism – the view according to which there is no guarantee that speakers within a community share a language and the notion (...) of idiolect is more fundamental than the notion of shared language.

A relativistic, i.e., Lorentz co-variant theory without constraints is formulated. This is possible if we allow the dynamical variables to depend on an invariant parameter τ. Thus we obtain a dynamical theory in spacetime, called relativistic dynamics. First the case of a point particle, and then of extended objects such as membranes of arbitrary dimensions are considered.

The invariant evolution parameter τ is often used in the formulation of a so-called unconstrained relativistic quantum theoryof a point particle. Such a theory is very elegant, and contains the usual Klein-Gordon or the Dirac particle as a special case. In the present paper we extend the unconstrained theory to describe a continuous set of point particles forming a string or, in general, a membrane of arbitrary dimension p.The action of this system is not invariant with respect to reparametrizations of (...) the evolution parameter τ and therefore there is no constraints among the dynamical variables, and no need for ghosts in the quantized theory. Then we show that such an unconstrained membrane is equivalent to a wiggly membranewhich has variable tension on its (p+1)-dimensional worldsheet. The equations of motion admit the usual well-known Dirac-Nambu-Goto membranes as particular solutions. (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.

Internalisti razloga smatraju da je prisutnost motiva preduvjet za postojanje razloga. Prema humeovskoj interpretaciji ovog stajališta, razlozi za djelovanje uvijek su relativni budući da njihovo postojanje ovisi o arbitrarnim elementima koji čine nečiji subjektivni motivacijski skup. Jedan od najvećih izazova humeovskom internalizmu predstavlja kantovska interpretacija internalističkog stajališta.

The main intention of Kantian approach is to prove the possibility of rational motivation and thus deny Humean internalism. In this article I critically examine this discussion and attempt to defend Humean internalism against one contemporary Kantian proposal. (shrink)
