The concept of “representation” is used broadly and uncontroversially throughout neuroscience, in contrast to its highly controversial status within the philosophy of mind and cognitive science. In this paper I first discuss the way that the term is used within neuroscience, in particular describing the strategies by which representations are characterized empirically. I then relate the concept of representation within neuroscience to one that has developed within the field of machine learning. I argue that the recent success of artificial neural (...) networks on certain tasks such as visual object recognition reflects the degree to which those systems exhibit inherent inductive biases that reflect the structure of the physical world. I further argue that any system that is going to behave intelligently in the world must contain representations that reflect the structure of the world; otherwise, the system must perform unconstrained function approximation which is destined to fail due to the curse of dimensionality, in which the number of possible states of the world grows exponentially with the number of dimensions in the space of possible inputs. An analysis of these concepts in light of philosophical debates regarding the ontological status of representations suggests that the representations identified within both biological and artificial neural networks qualify as legitimate representations in the philosophical sense.

"Well-publicized research in psychology tells us that over half of our attempts to change habitual behavior fail within one year. Even without reading the research, most of us will intuitively sense the truth in this, as we have all tried and failed to rid ourselves of one bad habit or another. The human story of habits and the difficulty of change has been told in many books - most of which will make only a quick reference to dopamine or the (...) "lizard brain" before moving on to practical tips and tricks for behavior change. In contrast, Stuck: The Neuroscience of Why Changing Our Behavior is So Hard will tell the brain's story about why behavior is so hard to change. Russell Poldrack offers an in-depth, yet entirely accessible, guide to the neuroscientific research on habits and habit change. Part I introduces the "anatomy of a habit," starting with the argument that the resilience of our habits stems largely from a mismatch between the environment in which our brains evolved and the one in which we now live, and continuing on to introduce current work on fear and anxiety, motivation, and cognitive control that bears on habit formation. Part II focuses on what neuroscience can tell us about breaking habits, introducing evidence-based strategies that give us the best possible chance to break cycles of bad behavior. Throughout the book, Poldrack offers a clear-eyed view of what neuroscience can tell us about habit change, and what it cannot - and importantly, how we know what we know"--. (shrink)

Cognitive neuroscience aims to map mental processes onto brain function, which begs the question of what “mental processes” exist and how they relate to the tasks that are used to manipulate and measure them. This topic has been addressed informally in prior work, but we propose that cumulative progress in cognitive neuroscience requires a more systematic approach to representing the mental entities that are being mapped to brain function and the tasks used to manipulate and measure mental processes. We describe (...) a new open collaborative project that aims to provide a knowledge base for cognitive neuroscience, called the Cognitive Atlas, and outline how this project has the potential to drive novel discoveries about both mind and brain.

We discuss recent progress in the development of cognitive ontologies and summarize three challenges in the coordinated development and application of these resources. Challenge 1 is to adopt a standardized definition for cognitive processes. We describe three possibilities and recommend one that is consistent with the standard view in cognitive and biomedical sciences. Challenge 2 is harmonization. Gaps and conflicts in representation must be resolved so that these resources can be combined for mark-up and interpretation of multi-modal data. Finally, Challenge (...) 3 is to test the utility of these resources for large-scale annotation of data, search and query, and knowledge discovery and integration. As term definitions are tested and revised, harmonization should enable coordinated updates across ontologies. However, the true test of these definitions will be in their community-wide adoption which will test whether they support valid inferences about psychological and neuroscientific data. (shrink)

ExcerptAll rational liberal philosophic positions have lost their significance and power. One may deplore this but I for one cannot bring myself to clinging to philosophic positions which have been shown to be inadequate. Leo Strauss, “Existentialism”1The Supreme Court decision on the Patient Protection and Affordable Care Act, the Obama administration's signature legislation on health care, attracted exceptional public attention, and rightly so. Health is a vital concern, and the topic is charged with acerbic party politics.

ExcerptProfound change in society may involve shifting control of political power, the character of economic systems, or access to resources, but it can also have to do with the structures of meaning we bundle together in various understandings of culture. This issue of Telos looks at the explosive forces located specifically in the intangible dimensions of culture and how they may play out in revolutionary or counter-revolutionary processes. No process has been more disruptive of inherited traditions and stable structures than (...) globalization, the spread of the dynamic economy of capitalism coupled with liberal democracy.

The concept of the public sphere is the touchstone of Peter Hohendahl's scholarship, which has been profoundly influential on both sides of the Atlantic. One is tempted to suggest that the public sphere is the central concept of Atlanticism. Historically, the urgency of publicness emerged, via Jürgen Habermas's foundational study, in the Federal Republic against the backdrop of the Nazi dictatorship.1 The pursuit of a public sphere represented an insistence on the desideratum of liberal democratic institutions in contrast to totalitarian (...) domination—whether the latter was understood as the absence of a public sphere or, alternatively, as the hyperpoliticization of the….

The “nation” has been the primary unit of political membership in modernity, typically stronger than “region” (the American 1865) and almost always stronger than “class” (the European 1914). Membership in the nation has meant citizenship, the basis of civil rights and civic responsibility within the rule of law. However “nation” is also related to the “people,” the source of all democratic power. The “people” was the population in the age of the democratic revolutions before anything like contemporary mass immigration. While (...) the Enlightenment notion of “the people” was not an ethnic definition, the romanticization of the term and its metamorphosis.. (shrink)

Are the arguments of the Frankfurt School still relevant? Modern Culture and Critical Theory investigates this question in the context of important issues in contemporary cultural politics: neoconservatism and new social movements, discontents with modernity and debates on postmodernism, the political hegemony of Ronald Reagan, and the cultural hegemony of structuralism and poststructuralism. Russell Berman thoughtfully explores the theories of Horkheimer, Adorno, Benjamin, Lyotard, and Foucault and their relevance to both historical and contemporary issues in literature, politics, and the (...) arts.

A study probing the ambiguities of German nationhood. Berman takes a theoretical perspective of cultural studies, exploring such themes as: the constitution of nationhood; what holds a citizenry together; and history's role in providing a framework for current identities and institutions.

It is difficult to start a discussion about religion. The topic irritates the modern public, especially the part that has been schooled in Critical Theory. Enlightenment hostility toward religion, which regularly goes far beyond skepticism, has profoundly shaped sensibilities and the habits of debate. Spoken or unspoken assumptions in the secular public sphere relegate religion to a fully private matter, and, therefore, not an appropriate topic for consideration, let alone a possible source for reflection on current theoretical or political matters. (...) The elaboration of theory within the project of modernity is taken to be fully separate from religion, or perhaps…. (shrink)

Matthias Küntzel's account of the centrality of anti-Semitism within jihadist ideology appeared in German in 2002. The text has been expanded and updated for this translation. The volume includes a foreword by Jeffrey Herf, who highlights key aspects of the argument and the context. Heir to the tradition of Critical Theory—the website of the original publisher, Ça ira, carries a quotation by Hans-Jürgen Krahl, Adorno's student and antagonist—Küntzel's forcefully argued presentation stretches from the origins of twentieth-century Islamism, with the founding (...) of the Muslim Brotherhood in 1928, to the worldwide wave of anti-Semitism that followed the 9/11 attacks.
