Regularization may be used as an alternative to dimensionality reduction when the number of variables in a model is much larger than the number of available observations. In a recent study from our group regularized regression was employed to quantify brain functional connectivity in a sample of healthy controls using a brain parcellation and resting state fMRI images. Here regularization is applied to evaluate resting state connectivity abnormalities at the voxel level in a sample of patients with schizophrenia. Specifically, ridge (...) regression is implemented with different degrees of regularization. Results are compared to those delivered by the weighted global brain connectivity method, which is based on averaged bivariate correlations and from the non-redundant connectivity method, a dimensionality reduction approach that applies supervised principal component regressions. Ridge regression is able to detect a larger set of abnormally connected regions than both GBC and NRC methods, including schizophrenia related connectivity reductions in fronto-medial, somatosensory and occipital structures. Due to its multivariate nature, the proposed method is much more sensitive to group abnormalities than the GBC, but it also outperforms the NRC, which is multivariate too. Voxel based regularized regression is a simple and sensitive alternative for quantifying brain functional connectivity. (shrink)

A posteriori physicalism is the combination of two appealing views: physicalism (i.e. the view that all facts are either physical or entailed by the physical), and conceptual dualism (i.e. the view that phenomenal truths are not entailed a priori by physical truths). Recently, some philosophers such as Goff (2011), Levine (2007) and Nida-Rümelin (2007), among others, have suggested that a posteriori physicalism cannot explain how phenomenal concepts can reveal the nature of phenomenal properties. In this paper, I wish to defend (...) a posteriori physicalism from this new and interesting challenge, by arguing that a posteriori physicalists have the resources to explain how phenomenal concepts can reveal at least something of what it would take for the corresponding phenomenal property to be instantiated.

The inference from conceivability to possibility has been challenged in numerous ways. One of these ways is the so-called phenomenal concept strategy, which has become one of the main strategies against the conceivability argument against physicalism. However, David Chalmers has recently presented a dilemma for the phenomenal concept strategy, and he has argued that no version of the strategy can succeed. In this paper, I examine the dilemma, and I argue that there is a way out of it. I conclude (...) that Chalmers has not posed any serious problem for the phenomenal concept strategy to succeed in blocking the conceivability argument. In doing so, my aim is not only to show that Chalmers’s argument has not refuted the phenomenal concept strategy, but also to clarify what any version of the strategy should achieve in order to be successful.

One of the main strategies against conceivability arguments is the so-called phenomenal concept strategy, which aims to explain the epistemic gap between physical and phenomenal truths in terms of the special features of phenomenal concepts. Daniel Stoljar has recently argued that the phenomenal concept strategy has failed to provide a successful explanation of this epistemic gap. In this paper my aim is to defend the phenomenal concept strategy from his criticisms. I argue that Stoljar has misrepresented the resources of the (...) strategy, which can indeed accomplish the required explanatory task, once it is properly understood. (shrink)

In this paper I examine Chalmers and Jackson’s defence of the a priori entailment thesis, that is, the claim that microphysical truths a priori entail ordinary non-phenomenal truths such as ‘water covers 60% of the Earth surface’, which they use as a premise for an argument against the possibility of a reductive explanation of consciousness. Their argument relies on a certain view about the possession conditions of macroscopic concepts such as WATER, known as ascriptivism. In the paper I distinguish two (...) versions of ascriptivism: reductive versus non-reductive ascriptivism. According to reductive ascriptivism, competent users of a concept have the ability to infer truths involving such concept from lower-level truths, whereas according to non-reductive ascriptivism, all that is required in order to be a competent user of a concept is to be able to infer truths involving that concept from other truths, which need not be lower-level truths. I argue, first, that the a priori entailment thesis is committed to reductive ascriptivism, and secondly, that reductive ascriptivism is problematic because it trivializes the notion of a priori knowledge. Therefore, I conclude that Chalmers and Jackson have not presented a convincing case for the claim that microphysical truths entail ordinary non-phenomenal truths a priori, especially when we understand this claim in the sense that is relevant for their argument against the possibility of a reductive explanation of consciousness.

The hard problem of consciousness is about how we could explain in physicalist terms why we are conscious. The meta-problem of consciousness is about how we could explain why we have a hard problem of consciousness. In this note I argue that the phenomenal concept strategy can in principle provide a satisfactory solution to the meta-problem.

What does it mean to say that some features, such as gender, race and sexual orientation, are socially constructed? Many scholars claim that social constructionism about a kind is a version of realism about that kind, according to which the corresponding kind is a social construction, that it, it is constituted by social factors and practices. Social constructionism, then, is a version of realism about a kind that asserts that the kind is real, and puts forward a particular view about (...) the nature of the kind, namely, that it is constituted by social factors and practices. Social constructivists about human kinds such as gender, race and sexual orientation often make an additional claim, namely, that these kinds are social constructions but they are typically believed to be biological kinds (that is, people are typically wrong about the nature of these kinds). Ron Mallon (2017) calls social constructions that are (falsely) taken to be biological kinds covert social constructions. This paper is about how we could have terms in our natural language that come to refer to covert social constructions. (shrink)

There is some cost to you in voting. While it may be small for some, it is significant for others. Some people go to a great deal of effort just to vote. What return do they get for this effort? Zilch! A single vote can only impact an election when there is a tie, which has essentially zero chance of happening in a state or national election. The typical response to this is "Well, what if everyone did that?" Of course, (...) that would be a disaster. But we are not talking about everyone, we are talking about ONE individual. (shrink)

Are sexual orientations freely chosen? The idea that someone’s sexual orientation is not a choice is very influential in the mainstream LGBT political movement. But do we have good reasons to believe it is not a choice? Going against the orthodoxy, William Wilkerson has recently argued that sexual orientation is partly constituted by our interpretations of our own sexual desires, and we choose these interpretations, so sexual orientation is partly constituted by choice. In this paper I aim to examine the (...) question of whether our interpretations of our own sexual desires are constitutive of our sexual orientations. I will argue that whereas Wilkerson’s argument for the claim that sexual orientations are in part constituted by our chosen interpretations of our sexual desires is not sound, there are good reasons for endorsing a weaker claim, namely, that there are different but equally apt descriptions of the same sexual desires, depending on which concepts we have.

The so-called “disquotational theory of truth” has not previously been developed much beyond the thesis that saying, for example, that ‘Snow is white’ is true amounts only to saying that snow is white. Marian David has set out to see what further sense can be made of the disquotational theory, and to compare its merits with those of correspondence theories of truth. His prognosis is that an intelligible disquotational theory of truth can be developed but will suffer from drastic shortcomings (...) that make it all but unusable. (shrink)

A collection of papers dealing with history as a way of knowing, not a mode of discourse.

Population control through discriminatory practices is found at all times in history. Never before, however, has use of the sciences been so close to achieving the creation of new mechanisms for generating human "subspecies". This study, which is based on a selected theoretical framework, deals with the biotechnological and bioethical challenges on the path to manipulation as concerns the development of potentially harmful practices in a pluralist context. Segregation or even the destruction of undesirable human beings is a frightening reflection (...) of an egocentric and largely prejudiced society. However, the future will not necessarily be obscure if Homo sapiens can act ethically and positively. (shrink)

The social phenomena discussed in this series of essays all center around the problem of individuals in groups faced with the choice of doing what is best for themselves or what is best for the group. Instances of the phenomena are called by many different names: "Volunteer's Dilemma", "Prisoner's Dilemma", "Collective Choice", "Rational Choice", "Social Choice", and "Voter's Paradox" to list just a few. Unfortunately, the academic programs that cover these various manifestations of the "individual vs. group" dilemma do not (...) fall under one discipline.

In this paper I examine the question of whether the characterization of physicalism that is presupposed by some influential anti-physicalist arguments, namely, the so-called conceivability arguments, is a good characterization of physicalism or not. I compare this characterization with some alternative ones, showing how it can overcome some problems, and I defend it from several objections. I conclude that any arguments against physicalism characterised in that way are genuine arguments against physicalism, as intuitively conceived.

El objetivo de este ensayo es mostrar algunos ejemplos del papel fundamental que tuvo la Biblia en la evangelización del Nuevo Mundo durante el siglo XVI. Tres aspectos serán estudiados aquí: 1) el intento inicial de traducir los textos bíblicos a las lenguas indígenas, finalmente frustrado; 2) la importancia de la Sagrada Escritura para dilucidar las estrategias políticas y religiosas a seguir con respecto al Nuevo Mundo, ejemplarizada en la cita de Lc 14,23; 3) los temas bíblicos en el teatro (...) de evangelización.

Sally Haslanger (2006) is concerned with the debate between so-called social constructionists and error theorists about a given category, such as race or gender. For example, social constructionists about race claim that race is socially constructed, that is, the kind or property that unifies all instances of the category is a social feature (not a natural or physical feature, as naturalists about race would hold). On the other hand, error theorists about race claim that the term ‘race’ is an empty (...) term, that is, nothing belongs to this category, since the conditions that something should satisfy in order to fall under ‘race’ are not satisfied by anything. What kind of evidence could we use in order to support one or another of these theories? It seems that this debate is in part semantic: what makes the case that a category is an empty one (and therefore error theory about it holds), as opposed to it being socially constructed, has to do with the meaning of the corresponding expression. In particular, in the case of race, some people have argued that our concept RACE is such that something will fall under it only if it is a natural property that can explain certain features. Arguably, there are no natural properties of human beings that can do the explanatory work that races are supposed to do, and therefore, error theorists have concluded that ‘race’ is an empty term, that is, there are no races (Appiah (1996)). (Some theorists have introduced new terms for a new property that is very similar to that of race and can do part of the explanatory work that races were supposed to do, but it does not have to satisfy all the conditions that races are supposed to satisfy. For instance, Appiah (1996) has introduced the notion of ‘racial identity’ to that effect.) These considerations suggest that if we want to find out whether a certain category is socially constructed, or whether an error theory about it is correct, we have to engage in.... (shrink)

Objectives To develop and test two educational programmes (interactive and passive) aimed at improving family doctors' (FD) prescribing practices and patient's knowledge and use of non-opioid analgesics (NOA).Methods The educational programmes were conducted in two family medicine clinics by using a three-stage approach: baseline evaluation, design, and implementation of educational activities, and post-programme evaluation. An interactive educational programme (IEP) was compared with a passive educational programme (PEP); both were participated by FDs and patients. The IEP for FDs comprised of workshops, (...) discussion groups, in-service training and guidelines, while for patients the IEP consisted of an interactive session with a video, leaflets and a discussion. The PEP consisted in delivering the guidelines to the FDs and the leaflets to patients. The effect of the programmes on the FDs was measured through the appropriateness of prescriptions and analysed using the differences-in-differences estimator (D-in-D), and on patients through changes in self-medication and in their knowledge about the proper use and adverse events by analysing the inter- and intra-group differences before and after the programmes.Results The IEP obtained better results to improve appropriate FDs prescription of NOA than PEP (D-in-D = 15%). Regarding the patients, the PEP group reached higher reduction of self-medication than the IEP group (13.4% vs. 9.1%); the knowledge of proper NOA use increased by 8.5% in both groups, whereas knowledge of NOA-related adverse events was better in the IEP (39.6%) than in the PEP group (9.2%).Conclusions The IEP was better to improve the doctors' abilities to prescribe NOAs, and both programmes improved patients' knowledge.

According to many philosophers, there is an explanatory gap between physical truths and phenomenal truths. Someone could know all the physical truths about the world, and in particular, all the physical information about the brain and the neurophysiology of vision, and still not know what it is like to see red (Jackson 1982, 1986). According to a similar example, someone could know all the physical truths about bats and still not know what it is like to be a bat (Nagel (...) 1974). We can conceive of an individual that is physically identical to me, molecule per molecule, but does not have any phenomenally conscious state whatsoever (Chalmers 1996). Some philosophers have argued that the explanatory gap shows that we cannot explain consciousness in physical terms (Levine 2001), or even that phenomenal consciousness is not physical and therefore physicalism is false (Chalmers 1996, 2002).

This paper gives an account of Colin McGinn's essay: "Can We Solve the Mind-Body Problem?". McGinn's answer to his own essay title is that the problem is forever beyond us due to the particular nature of our cognitive abilities.The present author offers a number of criticisms of the arguments which support this conclusion.

This essay is a defence of the traditional notion of qualia - as properties of consciousness that are ineffable, intrinsic, private and immediately apprehensible - against the eliminative attempts of Daniel Dennett in the influential article "Quining Qualia." It is suggested that a thorough exploration of the concept is an appropriate starting point for future explanations of qualia, and the essay ends with some possible explanations of the four traditional properties.

Daniel Stoljar has recently argued that comparing the zombie argument against physicalism with another influential argument in philosophy of mind, namely, the actor argument against behaviourism, can help to show why recent objections to the zombie argument fail. In this note I want to argue that the zombie argument and the actor argument have important differences, and, because of that, Stoljar's objections to some recent critiques of the zombie argument are not successful.

David Papineau [1999. “Normativity and Judgement.” Proceedings of the Aristotelian Society 73 : 16–43.] argues that norms of judgement pose no special problem for naturalism, because all such norms of judgement are derived from moral or personal values. Papineau claims that this account of the normativity of judgement presupposes an account of content that places normativity outside the analysis of content, because in his view any accounts of content that place normativity inside the analysis of content cannot explain the normativity (...) of judgement in the derivative way he proposes. Furthermore, he argues that normative accounts of content along those lines are independently problematic. In this paper I aim to respond to both objections, by arguing that normative accounts of content can be seen as naturalist accounts, even if they place normativity inside the analysis of content; and that normative accounts of content are compatible with a derivative account of norms of judgement of the sort Papi...

One compelling argument challenging the tenability of physicalism, which sees reality as fundamentally comprised of physical facts, is Jackson's knowledge argument. Through a powerful thought experiment involving the case of Mary, the super neuroscientist, the argument demonstrates how knowledge of phenomenal facts cannot be deduced from knowledge of physical facts. For allegedly leaving out phenomenal facts in its account of reality, physicalism is shown to be incomplete and hence mistaken. Physicalists respond to this argument in a variety of ways, challenging, (...) in turn, some aspects of the knowledge argument. This paper focuses on the replies of the ability hypothesis and the phenomenal concept strategy, which respectively try to block the two crucial moves in the knowledge argument: the establishment of an epistemic gap and the inference from the occurrence of this gap to the existence of an ontological gap. The paper critically examines how proponents of these two replies to the knowledge argument respond to some objections to maintain the viability of physicalism. (shrink)

In the Introduction to her recent translation of the Poetics, Miss Hubbard astutely recognizes the intellectual orientation of Aristotle's aesthetic theory. She observes that for Aristotle the concept of mimesis is intimately connected with that of mathesis and thus that the basic pleasure of art is the intellectual pleasure involved in learning. She then correctly identifies two levels of the learning process involved in mimesis: on a lower level it signifies the way in which children learn their first lessons but (...) on a much more sophisticated plane it denotes a process by which our understanding of ‘moral facts and moral possibilities’ is deepened. She perceptively concludes that if art is to achieve the goal set for it by Aristotle, it must have a significant relationship to ultimate truth. (shrink)

This comment on Ásta’s Categories we live by: the construction of sex, gender, race, and other social categories discusses Ásta’s arguments that the conferralist view on social properties does better than a response-dependence view concerning gender.

Just as the pleasant experience differs from the non-pleasant or unpleasant, and the aesthetic from the non-aesthetic, internally or qualitatively, and not merely in degree, or externally or relationally, so, it is natural to expect, a moment of moral living differs from a moral or immoral moment. Indeed, from many quarters, and most emphatically from the Stoic and Christian, we have been wont to hear that if we but leave our sinful or indifferent lives and put on righteousness or goodness, (...) we shall become new men or men reborn, even creatures of a different species. But according to many analyses of morality these promises of transfiguration or translation are nonsensical lies: for the moral experience, as exhibited in these analyses, differs from the non-moral or immoral only in respect of external relations, or at the most in degree. Whether the truth resides in the promises or in the analyses is, obviously, a question of no mean import. It is also a vast one, while the time and space that can be given up to an article are brief; hence the following will be barely more than a raising of the question, or a provocation, by means of rough statements, some dogmatic, others hypothetical.
