Interference phenomena are a well-known and crucial feature of quantum mechanics, the two-slit experiment providing a standard example. There are situations, however, in which interference effects are (artificially or spontaneously) suppressed. We shall need to make precise what this means, but the theory of decoherence is the study of (spontaneous) interactions between a system and its environment that lead to such suppression of interference. This study includes detailed modelling of system-environment interactions, derivation of equations (‘master equations’) for the (reduced) state (...) of the system, discussion of time-scales etc. A discussion of the concept of suppression of interference and a simplified survey of the theory is given in Section 2, emphasising features that will be relevant to the following discussion (and restricted to standard non-relativistic particle quantum mechanics.[1] A partially overlapping field is that of decoherent histories, which proceeds from an abstract definition of loss of interference, but which we shall not be considering in any detail.

Advances in assisted reproductive technologies can give rise to several ethical challenges. One of these challenges occurs when the reproductive desires of two individuals become incompatible and conflict. To address such conflicts, it is important to unbundle different aspects of (non)parenthood and to recognize the corresponding reproductive rights. This article starts on the premise that the six reproductive rights—the right (not) to be a gestational, genetic, and social parent—are negative rights that do not entail a right to assistance. Since terminating (...) or continuing a pregnancy is a form of assistance, the right (not) to be a gestational parent should enjoy primacy in conflicts. However, while refusing assistance may hinder the reproductive project of another person, “prior assistance” does not entitle someone to violate a reproductive right. Therefore, our analysis provides reasons to argue that someone has a right to unilaterally use cryopreserved embryos or continue the development of an entity in an extracorporeal gestative environment (i.e., ectogestation). Although this could lead to a violation of the right not to be a genetic parent, it does not necessarily entail a violation of the right not to be a social parent. (shrink)

Hassin recently proposed the “Yes It Can” (YIC) principle to describe the division of labor between conscious and unconscious processes in human cognition. According to this principle, unconscious processes can carry out every fundamental high-level cognitive function that conscious processes can perform. In our commentary, we argue that the author presents an overly idealized review of the literature in support of the YIC principle. Furthermore, we point out that the dissimilar trends observed in social and cognitive psychology, with respect to (...) published evidence of strong unconscious effects, can better be explained by the way how awareness is defined and measured in both research fields. Finally, we show that the experimental paradigm chosen by Hassin to rule out remaining objections against the YIC principle is unsuited to verify the new default notion that all high-level cognitive functions can unfold unconsciously.

Invariantists argue that the notion of concept in psychology should be reserved for knowledge that is retrieved in a context-insensitive manner. Contextualists argue that concepts are to be understood in terms of context-sensitive ad hoc constructions. I review the central empirical evidence for and against both views and show that their conclusions are based on a common mischaracterization of both theories. When the difference between contextualism and invariantism is properly understood, it becomes apparent that the way the question of stability (...) is currently investigated will not lead to a consensus. Instead of focusing directly on stability, we should turn our attention to other desiderata on a theory of concepts. In particular, I show that invariantism, but not contextualism, fails to account for compositionality and abstract concepts. (shrink)

Nelson’s programme for a stochastic mechanics aims to derive the wave function and the Schroedinger equation from natural conditions on a diffusion process in configuration space. If successful, this pro- gramme might have some advantages over the better-known determin- istic pilot-wave theory of de Broglie and Bohm. The essential points of Nelson’s strategy are reviewed, with particular emphasis on concep- tual issues relating to the role of time symmetry. The main problem in Nelson’s approach is the lack of strict equivalence (...) between the cou- pled Madelung equations and the Schroedinger equation. After a brief discussion, the paper concludes with a possible suggestion for trying to overcome this problem. (shrink)

It is a commonly held view in contemporary epistemology that for having knowledge it is necessary to have an appropriately based belief, although numerous different views exist about when a belief’s base is appropriate. Broadly speaking, they all share the view that one can only have knowledge if the belief’s base is in some sense truth-related or tracking the truth. Baseless knowledge can then be defi ned as knowledge where the belief is acquired and sustained in a way that does (...) not track the truth. I will argue that rejecting baseless knowledge leads to controversial consequences. The problem increases if we consider contrasting persons who know because of appropriate belief forming processes but who fail to possess further epistemic virtues such as understanding. I will not argue which belief bases constitute a suffi cient condition for knowledge. Rather I will stress the point that the common assumption that an appropriate basing relation constitutes a necessary condition for knowledge has controversial consequences. (shrink)

Resumo Neste artigo o autor apresenta cinco abordagens diferentes ao debate entre o platonismo e o nominalismo: a quantificacional, a reducionista, a dependência da mente / linguagem, a extensional versus intensional, a hierárquica. Cada uma apresenta suas vantagens e desvantagens que devem ser discutidas em detalhe. Palavras-chave : existência, meta-metafísica, nominalismo, platonismoIn this paper I present five different approaches to the debate between Platonism and Nominalism: the quantifier approach, the reductionist approach, the mind / language dependence approach, the extension versus (...) intension approach and the hierarchichal approach. Each one has its advantages and disadvantages that have to be discussed in detail. Keywords : existence, metametaphysics, nominalism, platonism. (shrink)

Un viaggio nell'arte medica del Rinascimento.

Binding needs to be task dependent, and cannot usefully be driven by properties of the stimulus alone. However, task dependent binding can only take place after the patterns in a stimulus have been identified. Thus pattern recognition needs to be done prior to binding. Synchronisation may be a consequence of pattern recognition and can be used to localise the pattern and tag its attributes at different levels of information processing.

As Jasper Reid argues in his book, there are plenty of reasons for taking More’s philosophy seriously, both as an example of early modern metaphysics and a speculative effort in its own terms. More’s metaphysics was experimental, fictional, and theological at once, for it deliberately and passionately engages with the study of nature, stories of preternatural apparitions and the mysteries of revealed religion. More’s philosophical inquiry feeds on experiments, stories, and visions, and these become an organic part of his metaphysical (...) equipment. This, of course, was a hazardous and edgy undertaking, which no doubt contributed to the bad... (shrink)

For the majority of people, death is a threat and the very idea of being dead a vexation. Dying is usually associated with pain which never goes away, pain which is the source of one’s anxiety. Bringing a child into this world can also be a painful process, and sometimes requires surgical procedures, but after a time the pain goes away and one can resume one’s normal life. The pain that leads to death, however, is a definitive pain, a final (...) experience which can no longer bear fruit. Death is haunted by the ghost of annihilation, of no longer existing, of an enduring frustration that human history will continue, perhaps even quite satisfactorily, without us.The mysterious and unknown dimension which surrounds the event of death, and what follows in its wake, is a threat to most human beings and a source of anxiety. No one likes the idea of ‘not knowing’ what will happen next, that curiosity is left unfulfilled.When the ‘expiry date’ is more or less established and approaching fast, something of a psychological crisis situation is induced in many people’s lives, one which in most circumstances has been latent all the while. Such a crisis can sometimes express itself in moments of troubled questioning. The three classical questions — in ‘philosophical crescendo’ — are: Can one expect anything after death, and if so, what? After death, will one have to give an account for the way one has lived this life? Is it really normal that one must die? (shrink)

It is a widely held view that persons have privileged knowledge about their own minds, although numerous different views on what this privilege exactly consists of exist. One possible way of interpreting it is to claim that persons can refer to their own mental states in a privileged way. I will argue that this view has to be extended. Our common-sense view about reference to mental states implies that besides privileges of first-person reference to one's own mental states, there also (...) exist privileges of third-person reference to the mental states of others: Other persons can refer to all of the mental states of a person in a way that the person cannot. In a next step, I will explain that persons can take two perspectives towards their own mental states: a first-person perspective and a third-person perspective. I will conclude that the possibilities of first-person reference from a third-person perspective are limited. (shrink)

Pincione argues that procedural constitutional guarantees of market freedoms best protect individuals from domination. If he is right, Philip Pettit's claim that various forms of state interference with private markets are needed to forestall domination will prove to be unwarranted. Pincione further contends that market freedoms are best protected by procedural rules for political decision-making, as opposed to constitutional guarantees of private property and other substantive rules.Central to his position are claims that the dispersion of economic power precludes domination, and (...) that free entry into markets furthers such dispersion. As against the idea that the state is in a better position to disperse economic power, Pincione argues that the constitutional provisions needed to implement that idea are contestable, and to that extent require interpretive powers that themselves involve domination. Only a constitution that, as a side effect of its procedures for political decision making, generates full private property rights holds out hope of shielding citizens from domination. This is so, because a plurality of suppliers of goods and services is a structural feature of the free market, in a sense of “structural” that matters for measurements of domination based on fairly uncontroversial claims about persons and resources.

Regarding the influence of François Rabelais on the Giordano Bruno‟s works, up to now the criticism have only taken into consideration the lexical and thematic analogies. This article individualizes, in a passage of the Oratio Valedictoria, a literal quotation from the Gargantua et Pantagruel, showing that Rabelais was a direct source of inspiration for Bruno. The protagonist of the passage is the pythagorean Apollonius of Tyana, a character well known by the Nolan, who mentioned him in many occasions. He represents (...) the ideal medium with the oriental wisdom, that had so much influence on the thought of Bruno. Besides, he embodies the model of the "natural magician" in which the philosopher repeatedly identified himself, both in his works and life. (shrink)

Several social and cultural developments have led to a rethinking of the place and meaning of friendship within the life of the Church, not least its relation to family (and marriage). Dietrich Bonhoeffer’s theology has great potential for informing such renewed reflection. At face value, he appears to count both Church and family among the divine ‘mandates’, leaving friendship to a realm of ‘freedom’ outside the mandates. Yet closer reading of his writings—not least his correspondence with Bethge—reveals, first, a more (...) singular role of the Church vis-à-vis the mandates (including family); and secondly, congeniality between friendship and the ‘vicarious representative’ practices that lie at the heart of Bonhoeffer’s ecclesiology. Together, these findings allow us to recognise family and friendship as complementary expressions of discipleship, each supporting the other precisely by setting a limit to the specific type of ‘vicarious representative’ responsibility entrusted to each.
