Guest Editors’ Introduction

In spite of the widespread belief that there is (or at least there was) a clearcut and deep opposition between two forms of philosophizing vaguely characterized as 'continental' and 'analytic', it is not easy to find actual examples of debates between philosophers that clearly belong to the opposed camps. Perhaps the reason is that, on the assumption that the alleged 'divide' is so deep, each side feels that there is no point in arguing against the other, for argumentation would quickly be replaced by invective. In this paper I analyse one of the few recent examples of an across-divide debate m the Searle m Derrida polemic. Using a threefold typology of debates, I try to show that, in spite of the violent and sarcastic tone employed by both contenders, there is enough common ground, questioning of not-argued-for assumptions, and serious argumentation (on both sides) to consider this debate more than just an irrational dispute.     

Conceptual Change,Crucial Experiments and Auxiliary Hypotheses. A Theoretical Contribution

Theories about conceptual change have been generally related to historical and philosophical analysis of science. Yet, there is still much debate on how ideas coming from the history of science and their implications can be applied in this field. Our study intends to investigate the complex structure of conceptual change, by making use of some particularly representative features of the History and Philosophy of science, while considering the structure of so-called crucial experiments and the specific role of implicit hypotheses. Due to their historical importance and logical reasoning aspects, examining these issues may contribute to understand how conceptual change may take place.     

Hilbert-style Presentations of Two Logics Associated to Tetravalent Modal Algebras

We analyze the variety of A. Monteiro’s tetravalent modal algebras under the perspective of two logic systems naturally associated to it. Taking profit of the contrapositive implication introduced by A. Figallo and P. Landini, sound and complete Hilbert-style calculi for these logics are presented.     

Allocentric versus idiocentric tendencies: Convergent and discriminant validation

Allocentric tendencies were studied with a multimethod questionnaire and Illinois undergraduates. Nine scales measuring different aspects of allocentrism were shown to have good reliability and to be intercorrelated, thus showing convergent validity. Factor analysis identified three aspects: subordination of personal to group goals, the ingroup as extension of the self, and ingroup identity. The scales also had satisfactory discriminant validity. Those high on idiocentric tendencies used equity and those high in allocentric tendencies used equality and need in distributing rewards. A second study found that those who are allocentric are more likely to emphasize the values of cooperation, equality, and honesty, and those who are idiocentric to emphasize the values of comfortable life, competition, pleasure, and social recognition. Those who were allocentric reported receiving more social support and a better quality of social support; those who were idiocentric were higher in achievement motivation, alienation, anomie, and reported greater loneliness.     

Zika virus and pregnant women: A psychological approach

Zika virus presents risk of physical harm to pregnant women, but the fear of infection is also affecting women around the world. There is a gap in the research on Zika virus in the areas involving the impact on the psychosocial well-being of pregnant women. Therefore, this study is aimed at the investigation of the psychosocial adjustment of pregnant women to the risks of Zika virus infection during pregnancy. We investigated 14 pregnant women who were classified in three different groups: six in the first trimester, five in the second trimester and three in the third trimester, aged from 28 to 40 years (33.43 ± 3.76 years). Content analysis was used to interpret data. Our results show that the psychosocial adjustment of participants was significantly negative and included five aspects: (1) negative feelings, (2) changes in family planning, (3) adopting new customs (avoiding places of risk, use of specific clothes and use of repellent), (4) changed attitudes regarding body image and (5) feeling of external demand regarding prevention. The fear of Zika virus infection and all its associated risks have a negative biopsychosocial impact on the pregnant women in this study.     

Neuroscience and the possibility of locally determined choices: Reply to Adina Roskies and Eddy Nahmias

In a previous paper, I argued that neuroscience and psychology could in principle undermine libertarian free will by providing support for a subset of what I called “statements of local determination.” I also argued that Libet-style experiments have not so far supported statements of that sort. In a commentary to the paper, Adina Roskies and Eddy Nahmias accept the claim about Libet-style experiments, but reject the claim about the possibilities of neuroscience. Here, I explain why I still disagree with their conclusion, despite being sympathetic to a lot of what they say in support of it.
