euroscience of Rule-Guided Behavior brings together, for the first time, the experiments and theories that have created the new science of rules. Rules are central to human behavior, but until now the field of neuroscience lacked a synthetic approach to understanding them. How are rules learned, retrieved from memory, maintained in consciousness and implemented? How are they used to solve problems and select among actions and activities? How are the various levels of rules represented in the brain, ranging from simple (...) conditional ones if a traffic light turns red, then stop to rules and strategies of such sophistication that they defy description? And how do brain regions interact to produce rule-guided behavior? These are among the most fundamental questions facing neuroscience, but until recently there was relatively little progress in answering them. It was difficult to probe brain mechanisms in humans, and expert opinion held that animals lacked the capacity for such high-level behavior. However, rapid progress in neuroimaging technology has allowed investigators to explore brain mechanisms in humans, while increasingly sophisticated behavioral methods have revealed that animals can and do use high-level rules to control their behavior. The resulting explosion of information has led to a new science of rules, but it has also produced a plethora of overlapping ideas and terminology and a field sorely in need of synthesis. In this book, Silvia Bunge and Jonathan Wallis bring together the worlds leading cognitive and systems neuroscientists to explain the most recent research on rule-guided behavior. Their work covers a wide range of disciplines and methods, including neuropsychology, functional magnetic resonance imaging, neurophysiology, electroencephalography, neuropharmacology, near-infrared spectroscopy, and transcranial magnetic stimulation. This unprecedented synthesis is a must-read for anyone interested in how complex behavior is controlled and organized by the brain. (shrink)

The paper has two main aims. The first is to reformulate Hempel's version of the thesis of the symmetry of explanation and prediction, as regards the deductive covering-law model, so as to generalise it and make it no longer subject to some of the criticisms which have been directed at it (Section II). The second aim is to consider, with special critical reference to Hempel's recent treatment in Aspects of Scientific Explanation (New York and London, 1965), some central criticisms of (...) both the constituent parts of the above symmetry thesis, viz. that adequate explanations are potentially predictive (Section III), and that adequate predictive arguments are potentially explanatory (Section IV).

There is a widespread belief, more often implied than explicitly asserted, that Hume considered all necessary propositions to be analytic.Of course Hume did not use the analytic-synthetic distinction explicitly. This only come to the forefront with Kant; and it is Kant who is probably the main source of the above-mentioned belief. Kant ascribed to Hume the view that mathematical propositions are, in his terminology, analytic. If this is correct, then since mathematics was for Hume the paradigm of a body of (...) necessary truths, it is plausible to infer that he considered necessary propositions to be one and all analytic. The absence in Hume's writings of the analytic-synthetic terminology is by no means decisive: though he did not have the terms he may well have possessed the concepts, as evidenced by his use of them.

According to Sir Karl Popper, there is a harmful approach to the social sciences called 'historicism'. This takes their principal aim to be historical prediction of an unconditional sort and the chief means to this the discovery of laws of historical development. The chief exemplar is held to be Marx. This paper distinguishes two possible sorts of laws of historical development. Popper's arguments against each are rejected. Which sort it is most plausible to ascribe to Marx is considered. Four models (...) of historical determinism are distinguished and the question of Marx's view or views on the question is discussed in terms of them. (shrink)

When we start with the wrong question, no matter how good an answer we get, it won’t give us the results we want. Rather than joining the throngs who are asking, When will this economic crisis be over? Jim Wallis says the right question to ask is How will this crisis change us? The worst thing we can do now, Wallis tells us, is to go back to normal. Normal is what got us into this situation. We need (...) a new normal, and this economic crisis is an invitation to discover what that means. Some of the principles Wallis unpacks for our new normal are . . . • Spending money we don’t have for things we don’t need is a bad foundation for an economy or a family. • It’s time to stop keeping up with the Joneses and start making sure the Joneses are okay. • The values of commercials and billboards are not the things we want to teach our children. • Care for the poor is not just a moral duty but is critical for the common good. • A healthy society is a balanced society in which markets, the government, and our communities all play a role. • The operating principle of God’s economy says that there is enough if we share it. • And much, much more . . . In the pages of this book, Wallis provides us with a moral compass for this new economy—one that will guide us on Wall Street, Main Street, and Your Street. Embracing a New Economy Getting back to "the way things were" is not an option. It is time we take our economic uncertainty and use it to find some moral clarity. Too often we have been ruled by the maxims that greed is good, it’s all about me, and I want it now. Those can be challenged only with some of our oldest and best values—enough is enough, we are in it together, and thinking not just for tomorrow but for future generations. Jim Wallis shows that the solution to our problems will be found only as individuals, families, friends, churches, mosques, synagogues, and entire communities wrestle with the question of values together.

"This is an excellent textbook on Neoplatonism which gives the reader a very concise and lucid overview of the basic doctrines and leading thinkers of the last great philosophy to emerge before the Christianization of the Roman Empire. I’ve no doubt that my students next semester will benefit from the analyses contained in the book. The contents of the chapters are very informative and adequately place developments in their socio-cultural context." --Michael B. Simmons, Auburn University at Montgomery.

Brian Ellis has argued that the assigning of forces is, in the final analysis, a matter of convention. This conclusion is backed by the premises (1) that forces and force-effects are necessary and sufficient for each other, and (2) that the classification of some state of affairs as a force-effect is at least partly conventional. We argue that the first premise is false, that the second premise is ambiguous as between several senses of "conventional," and finally that he has not (...) established that force-effects are conventional in the sense required for the conclusion he wishes to draw.
