According to a familiar objection to Davidson's causal theory of action, reasons are not causes qua reasons unless explanations of actions fit reason and action into a nomic nexus. The focus of this criticism should really be redirected to the issue of whether or not Davidson's theory provides an account of the explanatory force of explanations of actions.

We propose a model mechanism for the initiation and spatial positioning of teeth primordia in the alligator, Alligator mississippiensis. Detailed embryological studies by Westergaard and Ferguson (1986, 1987, 1990) have shown that jaw growth plays a crucial role in the developmental patterning of the tooth initiation process. Based on biological data we develop a dynamic patterning mechanism, which crucially includes domain growth. The mechanism can reproduce the spatial pattern development of the first seven teeth primordia in each half jaw (...) of A. mississippiensis. The results for the precise spatio-temporal sequence compare well with experiment. Simulation of the model also predicts that certain transplantations can alter the spatial sequence of teeth primordia initiation. (shrink)
Endothelial cells, when cultured on gelled basement membrane matrix exert forces of tension through which they deform the matrix and at the same time they aggregate into clusters. The cells eventually form a network of cord-like structures connecting cell aggregates. In this network, almost all of the matrix has been pulled underneath the cell cords and cell clusters. This phenomenon has been proposed as a possible model for the growth and development of planar vascular systems in vitro. Our hypothesis is (...) that the matrix is reorganized and the cellular networks form as a result of traction forces exerted by the cells on the matrix and the latter's elasticity. We construct and analyze a mathematical model based on this hypothesis and examine conditions necessary for the formation of the pattern. We show cell migration is not necessary for pattern formation and that isotropic, strain-stimulated traction is sufficient to form the observed patterns. (shrink)
In 2007, Massachusetts instituted a universal coverage health plan that requires all citizens to purchase insurance. I argue that there is nothing wrong in principle with the use of an individual mandate to force citizens to secure health insurance. I argue that state neutrality is not tenable on this issue. Then I proceed to show that even if state neutrality were viable, it is not a violation of state neutrality (thought of as neutrality of intent) to force citizens to insure (...) themselves with the primary purpose of securing the normative good of health. I adapt recent work on universal medical coverage to demonstrate that such a mandate is in keeping with several principles of fairness shared in liberal democratic societies. This argument not only applies to the Massachusetts plan but likely to any other health care coverage schemes using individual mandates in the US political context, including recently passed federal health care reform measures. However, even though the Massachusetts plan may provide increased access to health care for many, there are still legitimate worries that it currently places disproportionate financial burdens on the working poor and thus will need refinement.

A philosophical approach to interracial dialogue in North America is based on moral and epistemological principles defended by James M. Jones, Lawrence Thomas, and Cornel West. The different perspectives of the racial majority and racial minorities give rise to different moral obligations.
Gliomas are diffuse and invasive brain tumors with the nefarious ability to evade even seemingly draconian treatment measures. Here we introduce a simple mathematical model for drug delivery of chemotherapeutic agents to treat such a tumor. The model predicts that heterogeneity in drug delivery related to variability in vascular density throughout the brain results in an apparent tumor reduction based on imaging studies despite continual spread beyond the resolution of the imaging modality. We discuss a clinical example for which the (...) model-predicted scenario is relevant. The analysis and results suggest an explanation for the clinical problem of the long-standing confounding observation of shrinkage of the lesion in certain areas of the brain with continued growth in other areas.

Austrian economics - the school of thought associated with Carl Menger, Frederick von Weiser, Eugen von Bohm-Bawerk, and in this century, Ludwig von Mises, Friedrich Hayek, Murray N. Rothbard, and Israel Kirzner - is based on a framework of methodological principles and assumptions much at variance with those of traditional or 'orthodox' economists. Robert Nozick, in his 'On Austrian Methodology', focuses attention on the most fundamental features of this framework, and subjects them to a thoroughgoing and scathing analysis. (...) Singled out for detailed and critical review are: (1) the praxeological concepts of methodological individualism; (2) the claim that economics is an a priori science of human action; (3) the nature of preference and its relation to choice and action; and (4) the assumptions of time-preference theory. Although Nozick does not consider Austrian views on business cycles, market process analysis, the coordinative and informational effects of the price system, competition, and several other fundamental aspects of praxeology, his criticism strikes at the very root of the praxeological school. This paper attempts to refute each criticism made of the praxeological school by Nozick on a point-by-point basis. It thus follows the same pattern as the original paper, and scrutinizes in detail the arguments made by its author. (shrink)
In this nicely written book, Dale Murray critically discusses the moral rights posited by Robert Nozick in Anarchy, State, and Utopia. His focus is on these rights and not on Nozick's arguments about the justness of the state. He argues that Nozick's rights to compensation give rise to rights to government-financed health care and that Nozick should recognize a natural right to enough goods to ensure a reasonable chance of living a decent and meaningful life (if feasible for (...) all). Murray also discusses issues such as the role of invisible hand arguments, moralized conceptions of freedom, and the issue of whether just steps (transactions) preserve the justice of situations.

In the longstanding debate between liberals and libertarians over the morality of redistributive labor taxation, liberals such as John Rawls and Ronald Dworkin have consistently taken the position that such taxation is perfectly compatible with individual liberty, whereas libertarians such as Robert Nozick and Murray Rothbard have adopted the (very) contrary position that such taxation is tantamount to slavery. I will demonstrate over the course of this paper that their debate over redistributive labor taxation can be usefully reconstituted (...) as a debate over the incidents (or components) of self-ownership, with liberals making the case for a narrow definition of the concept and libertarians arguing for a broad one. By using what Alan Ryan has called the "language of proprietorship," we will be able to pinpoint the source of their disagreement and to assess the relative strengths of their arguments. We will also discover that the respective definitions of self-ownership used by liberals and libertarians are deeply problematic--though for entirely different reasons. (shrink)
Dearly beloved, I want to thank Brother Tim O’Connor for his candid reactions to my published sermons this Sunday morning, and I welcome you all, in the spirit of ecumenicism, to the Church of Fundamentalist Naturalism. Before the collection plate is passed, let me tell you a bit more about the Church. Our symbol is of course the Darwin-fish, the four-legged evolver that echoes the ancient fish symbol of Christianity. I was wearing my Darwin-fish lapel pin at an evolutionary theory (...) conference a few years ago, and the physicist Murray Gell-Mann came up to me and after reminding me of what he said was the first known acronym-- I?1??, the Greek word for fish-- I??”?? ??4??”? 1,”< ?4”? ???0?, Jesus Christ, God the son and savior–he asked me what D-A-R-W-I-N stood for. I said I’d get back to him and went off to have a cup of coffee while dredging up what I could of my high school Latin. I came up with something I’m quite happy with: Delere Auctorem Rerum Ut Universum Infinitum Noscere: Destroy the Author of things in order to understand the infinite universe! That, it seems to me, is our key insight about Darwin’s dangerous idea: in a single non-miraculous stroke, it unites the world of meaning and purpose and design with the world of meaningless matter and mechanism, cause and effect.

attempt to justify the State, or at least a minimal State confined to the functions of protection. Beginning with a free-market anarchist state of nature, Nozick portrays the State as emerging, by an invisible hand process that violates no one’s rights, first as a dominant protective agency, then to an "ultra-minimal state," and then finally to a minimal state. Before embarking on a detailed critique of the various Nozickian stages, let us consider several grave fallacies in Nozick’s conception itself, each (...) of which would in itself be sufficient..

The consistent histories reformulation of quantum mechanics was developed by Robert Griffiths, given a formal logical systematization by Roland Omn\`{e}s, and under the label `decoherent histories', was independently developed by Murray Gell-Mann and James Hartle and extended to quantum cosmology. Criticisms of CH involve issues of meaning, truth, objectivity, and coherence, a mixture of philosophy and physics. We will briefly consider the original formulation of CH and some basic objections. The reply to these objections, like the objections themselves, (...) involves a mixture of physics and philosophy. These replies support an evaluation of the CH formulation as a replacement for the measurement, or orthodox, interpretation. (shrink)
Social constructionists believe that experimental evidence plays a minimal role in the production of scientific knowledge, while rationalists such as myself believe that experimental evidence is crucial in it. As one historical example in support of the rationalist position, I trace in some detail the theoretical and experimental research that led to our understanding of beta decay, from Enrico Fermi’s pioneering theory of 1934 to George Sudarshan and Robert Marshak’s and Richard Feynman and Murray Gell-Mann’s suggestion in 1957 (...) and 1958, respectively, of the V–A theory of weak interactions. This is not a history of an unbroken string of successes, but one that includes incorrect experimental results, incorrect experiment-theory comparisons, and faulty theoretical analyses. Nevertheless, we shall see that the constraints that Nature imposed made the V–A theory an almost inevitable outcome of this theoretical and experimental research. (shrink)
With the advent of quantum theory, the philosophical distinction between “what appears to be” and “what is reasoned to be” has once again, after several centuries of easy dismissal by classical mechanistic materialism, become an important feature of physics. In recent well-regarded interpretations of quantum physics, including those proposed by Robert Griffiths, Roland Omn s, and Nobel laureate Murray Gell-Mann, we have seen careful investigations into the physical (i.e., not “merely philosophical”) distinction between the order of contingent causal (...) relation and the order of necessary logical implication . I argue that a careful philosophical exploration of the function of the logical order in modern interpretations of quantum physics compels the abandonment of derivative classical, dualistic understandings of “determinism versus indeterminism,” “logical necessity versus causal contingency,” “subject versus object,” “epistemic versus ontological,” among other fundamental dualisms. The incoherence underlying this classical understanding of these principle-pairs as mutually exclusive features of reality can be relieved if they are instead understood as mutually implicative features of fundamental units of relation or “quantum praxes.”.

Miller and Rodgers (2001) proposed a central nervous system based Ontogenetic Bonding System that operates across the life course to promote succorant, 1 affiliative, sexual, and nurturant bonds. I discuss features of this theoretical framework that can inform Depue & Morrone-Strupinsky's (D&M-S's) model. Most important, I suggest that the affiliative reward processes D&M-S describe are better conceptualized as subserving the affect/motivation of affection.
