Communicative Reason Juergen Habermas, interviewed by Christoph Demmerling and Hans-Peter Krueger
(2016)
Jurgen Habermas explicates the concept of communicative reason. He explains the key assumptions of the philosophy of language and social theory associated with this concept. Also discussed is the category of life-world and the role of the body-mind difference for the consciousness of exclusivity in our access to subjective experience. as well as the role of emotions and perceptions in the context of a theory of communicative action. The question of the redemption of the various validity claims as they are associated with the performance of speech acts is related to processes of social learning and to the role of negative experiences. Finally the interview deals with the relationship between religion and reason and the importance of religion in modern, post-secular societies. Questions about the philosophical culture of our present times are discussed at the end of the conversation.
In this Comment, we review the results of pattern formation in a reaction-diffusion-advection system following the kinetics of the Gray-Scott model. A recent paper by Das [Phys. Rev. E 92, 052914 (2015)] shows that spatiotemporal chaos of the intermittency type can disappear as the advective flow is increased. This study, however, refers to a single point in the space of kinetic parameters of the original Gray-Scott model. Here we show that the wealth of patterns increases substantially as some of these parameters are changed. In addition to spatiotemporal intermittency, defect-mediated turbulence can also be found. In all cases, however, the chaotic behavior is seen to disappear as the advective flow is increased, following a scenario similar to what was reported in our earlier work [I. Berenstein and C. Beta, Phys. Rev. E 86, 056205 (2012)] as well as by Das. We also point out that a similar phenomenon can be found in other reaction-diffusion-advection models, such as the Oregonator model for the Belousov-Zhabotinsky reaction under flow conditions.
The Gradient Symbolic Computation (GSC) model presented in the keynote article (Goldrick, Putnam & Schwarz) constitutes a significant theoretical development, not only as a model of bilingual code-mixing, but also as a general framework that brings together symbolic grammars and graded representations. The authors are to be commended for successfully integrating a theory of grammatical knowledge with the voluminous research on lexical co-activation in bilinguals. It is, however, unfortunate that a certain conception of bilingualism was inherited from this latter research tradition, one in which the contrast between native and non-native language takes a back seat.
It is argued that, despite differences in cultural norms and practices, the evidence for a link between violent media use and aggression is remarkably consistent across different countries. Along with evidence that different operationalizations of violent media use also converge across countries, these findings strengthen the conclusion that violent media are a risk factor for aggression and validate the psychological explanations for these effects. However, we need comparative studies based on a consistent methodology and a theory-based selection of cultural difference variables to properly examine the potential impact of culture on the association between violent media use and aggression.
