We give an explicit solution of a model Boltzmann kinetic equation describing a gas between two walls maintained at different temperatures. In the model, which is essentially one-dimensional, there is a probability for collisions to reverse the velocities of particles traveling in opposite directions. Particle number and speeds (but not momentum) are collision invariants. The solution, which depends on the stochastic collision kernels at the walls, has a linear density profile and the energy flux satisfies Fourier's law.

"--Brian Greene, Columbia University "This book includes material that is intellectually innovative and comes as a surprise even to specialists in the field.

Originally published in 1963, this classic book is a rethinking of the history of Western political philosophy. Charles N. R. McCoy contrasts classical-medieval principles against the "hypotheses" at the root of modern liberalism and modern conservativism. In Part I, "The Classical Christian Tradition from Plato to Aquinas," the author lays the foundation for a philosophical "structure" capable of producing "constitutional liberty." Part II, "The Modern Theory of Politics from Machiavelli to Marx," attempts to show, beginning with Machiavelli, the reversal and (...) destruction of the pre-modern "structure" postulated in Part I. McCoy stresses the great contributions of Aristotle to political thought found in his more familiar Ethics and Politics, but also includes key insights drawn from Metaphysics and Physics. These contributions are developed and perfected, McCoy argues, by Augustine and Aquinas. Two other important features include McCoy's epistemological insights into Plato's work that will be new to many readers and the author's juxtaposition of traditional natural law with "the modernized theory of natural law." The modern account of autonomous natural law, in McCoy's view, helps explain the totalitarian direction of key aspects of modern political thought. This classic volume on the origins of modern philosophical thought remains a standard in the field. (shrink)

This paper answers the title question, “Yes,” on both counts. The first part of the paper argues that modern liberals are socialists, and the second part argues that they are also social democrats. The main idea behind the first argument is that the state has effectively taken control of the incidents of ownership through its taxation, spending, and regulatory policies. The main idea behind the second argument is that the institutions of social democracy are replicated by the institutions favored by (...) modern American liberalism. Specifically, the takeover of the American healthcare system, Social Security, employers' mandatory contributions to unemployment insurance, and workers' compensation insurance replicate the institutions of social democracy.

To understand the distinctive characteristics of the institutions of law, one needs to understand the idea of law. Understanding the nature of law is not ultimately a matter of achieving a careful description of social practices but a matter of grasping the idea towards which those practices must be understood as oriented. The idea of law is the focal point that enables us to make coherent sense of the otherwise diverse features of practice, but it is not itself a matter (...) of observable practice. It resembles a notional point in space that enables us to grasp the relationship between various parts of a complex drawing, although in itself it forms no part of the drawing. But how is such an idea to be investigated? We expect a clear understanding of the idea of law to explain our settled understandings about what will and will not count as an instance of legal ordering. We expect it, in other words, to explain some at least of the minimum conditions for applicability of the idea. But, since the idea of law is invoked within the practices of law, we also expect a philosophical understanding of that idea to clarify its role in guiding and orienting practice, and not simply in describing practice. Although the practices of law are oriented towards the idea of law, that idea is not straightforwardly available to be read in the surface appearance of the practices. For such practices, while involving systematic appeal to the idea of law, operate for the most part on the basis of that unreflective conformity that assists the stable functioning of most human institutions. Can we begin by identifying a "minimum specification" of the concept of law, in the form of a set of conditions without which nothing could count as law at all? From such a minimum specification, can we proceed in some orderly and intellectually defensible way towards "later phases" of the concept, with their "qualitative changes as well as additions and complications"? The possibility is worth exploring, however unfashionable may be the philosophical viewpoint from which it springs. Fuller's famous story of Rex, and his failed attempts to enact law, identifies the minimum conditions that something must satisfy in order to count as an instance of law. Fuller's theory becomes interesting when he proceeds to demonstrate that the eight desiderata (identified as minimum conditions), when taken collectively, be regarded as a guiding ideal for legal thought: the ideal that we usually label "the rule of law". Fuller claimed that his eight requirements represent an "inner morality of law". Hart's critique of Fuller appeared to suggest that the moral value of compliance with the eight requirements is wholly contingent upon the law's content, and that the eight requirements are more akin to precepts of efficiency than to moral standards. This criticism has been widely endorsed as correct. In fact, the criticism is not correct. The eight requirements are not principles of efficacy, but (when taken together) represent a moral ideal for legal systems. Fuller never really succeeded in giving a clear explanation of the moral status of his eight requirements. I argue that Fuller's eight desiderata represent an intrinsically moral ideal that we may call "freedom as independence from the power of another". This is the aspect of freedom that distinguishes the slave from the free man. My theory seeks to establish the existence of a very tight and necessary connection between law and morality. Positivists will find it impossible to deny that governance by law involves some degree of compliance with Fuller's eight requirements, and that such compliance necessarily involves the realisation of some degree of freedom as independence. If they are tempted to deny that freedom as independence is a distinct aspect of freedom, they must also argue that connections between slavery and the lack of freedom are purely contingent. If they accept that the lack of freedom as independece is what makes a slave a slave, but they deny that freedom as indepenence is a moral value, they must say that there is nothing intrinsically morally wrong with slavery: the moral wrongness of slavery would then have to be seen as stemming from purely contingent features of the slave's position. The value of freedom as independence may be thin. But it is real, it is genuinely valuable, and it is tightly connected to the existence of law. (shrink)

Die Herrschaft des Behaviorismus in der Psychologie ist gebrochen! Das ist die Ausgangsthese dieses Buches, die im Rahmen des Modells revolutionärer Wissenschaftsentwicklung (Kuhn) als Behauptung eines Paradigmawechsels präzisiert wird. Die Argumentation beschränkt sich nicht nur auf den Nachweis des Niedergangs des Behaviorismus, sondern gibt auch konstruktiv das mögliche neue Paradigma an: als Psychologie des reflexiven Subjekts, das wie der Wissenschaftler (subjektive) Theorien aufstellt, überprüft, bewertet. Der Aufriss einer solchen Psychologie des epistemischen Subjekts unter allgemein-, sozial-, pädagogisch- und klinisch-psychologischem Aspekt thematisiert (...) vor allem: die Rationalität der Reflexionen, Normenkritik und -begründung im Austausch von wissenschaftlichen und naiven Theorien sowie die Berücksichtigung von Reflexivität in der therapeutischen Praxis. Die Rückwendung dieser pychologisch-metatheoretischen Perspektiven auf die Wissenschaftstheorie führt auch zu einer neu. (shrink)

By ‘the logic of religious language’ I understand both a problem: What is the correct account of the logic of religious language? and a theme, a recurrent theme in the modern philosophical discussion of religion, which raises a related but distinguishable question: Is the approach to religion of linguistic analysis an adequate approach? Can we do justice to the logic of religious language by attending to the recognition and analysis of different linguistic forms?

Abstract Global climate change will have a strong impact on Nigeria, particularly on agricultural production and associated livelihoods. Although there is a growing scientific consensus about the impact of climate change, efforts so far in Nigeria to deal with these impacts are still rudimentary and not properly coordinated. There is little evidence of any pragmatic approach towards tracking climate change in order to develop an evidence base on which to formulate national adaptation strategies. Although Nigeria is not alone in this (...) regard, the paper asserts that National Climate Change Adaptation Strategy could help address this situation by guiding the integration of climate change adaptation into government policies, strategies, and programs, with particular focus on the most vulnerable groups and the agricultural sectors. There is an urgent need to adopt abatement strategies that will provide economic incentives to reduce the risk from disasters, such as developing agricultural practices that are more resilient to a changing climate.
