The business community of Canada manifests questionable moral and ethical standards in its criticism of government spending, since it itself bears considerable responsibility for the increase in government spending and budget deficits. The contradiction arises from the failure of the business community to recognize the liberalization of society at large and the associated social responsibility for the well-being of its citizens; a well-being manifested in income maintenance programmes, in access to education and training, in health care, and others. The failure (...) to recognize such expectations is manifested in its failure to provide adequately for the retirement of its employees, for the health care of its employees, for laid-off and seperated employees, thereby shifting the burden to government. Further, it has failed to assume responsibility for the training and retraining of the workers it employs, including high-level workers trained specifically to its purposes in business schools. While expecting government to bear full financial responsibility for income maintenance, health, education and training, the business community makes every effort to deny government the revenues it needs to meet its obligations. The avoidance of tax payments stands high amongst business objectives, manifested in the employment of highly paid accountants and tax lawyers specifically for the purpose. Finally, in their criticism of government spending, business spokesmen deliberately fail to distinguish between consumption spending and capital investment spending, notwithstanding the significant contribution to the production infrastructure of the economy of government investment expenditures. If the capital expenditures were to be taken out of the government's budget, the deficit will decrease substantially. (shrink)

Science and the End of Ethics examines some of the most important positive and negative implications that science has for ethics. Addressing the negative implications first, author Stephen Morris discusses how contemporary science provides significant challenges to moral realism. One threat against moral realism comes from evolutionary theory, which suggests that our moral beliefs are unconnected to any facts that would make them true. Ironically, many of the same areas of science (e.g. evolutionary biology, neuroscience, psychology) that present difficulties (...) for moral realism point to a new ethical approach that focuses on achieving some of the key practical goals shared by ethicists. Chief among these is how to increase amicable behavior among people. (shrink)

By , we denote the system of second-order arithmetic based on recursive comprehension axioms and Σ10 induction. is defined to be plus weak König's lemma: every infinite tree of sequences of 0's and 1's has an infinite path. In this paper, we first show that for any countable model M of , there exists a countable model M′ of whose first-order part is the same as that of M, and whose second-order part consists of the M-recursive sets and sets not (...) in the second-order part of M. By combining this fact with a certain forcing argument over universal trees, we obtain the following result : if proves X!Y with arithmetical, so does . We also discuss several improvements of this results. (shrink)

We investigate the provability or nonprovability of certain ordinary mathematical theorems within certain weak subsystems of second order arithmetic. Specifically, we consider the Cauchy/Peano existence theorem for solutions of ordinary differential equations, in the context of the formal system RCA 0 whose principal axioms are ▵ 0 1 comprehension and Σ 0 1 induction. Our main result is that, over RCA 0 , the Cauchy/Peano Theorem is provably equivalent to weak Konig's lemma, i.e. the statement that every infinite {0, 1}-tree (...) has a path. We also show that, over RCA 0 , the Ascoli lemma is provably equivalent to arithmetical comprehension, as is Osgood's theorem on the existence of maximum solutions. At the end of the paper we digress to relate our results to degrees of unsolvability and to computable analysis. (shrink)

Tube feeding is often presented as a nearly risk free and beneficial treatment for patients with dementia. But evidence shows that its benefits are illusory, while its risks are greater than many realize. Assisted oral feeding and good hospice care are better options.

The thesis that scientists give greater weight to novel predictions than to explanations of known facts is tested against historical cases in physical science. Several theories were accepted after successful novel predictions but there is little evidence that extra credit was given for novelty. Other theories were rejected despite, or accepted without, making successful novel predictions. No examples were found of theories that were accepted primarily because of successful novel predictions and would not have been accepted if those facts had (...) been previously known. (shrink)

The interface between religion, psychiatry, and ethics is often a locus for considerable controversy. This article focuses on the response of American psychiatry to religious nonconformism, and to religious conversion generally. At issue is the societal pressure against unpopular religious movements. The author argues for an ethic that conserves the freedom of religious conscience, and that guards against inquisitions in the guise of medical expertise and nosology.

This paper examines the way Charles Darwin applied his domestic breeding analogy to the practical workings of species evolution: that application, it is argued, centered on Darwin's distinction between methodical and unconscious selection. Methodical selection, which entailed pairing particular individuals for mating purposes, represented conditions of strict geographic isolation, obviously useful for species multiplication (speciation). By contrast, unconscious selection represented an open landmass with a large breeding population. Yet Darwin held that this latter scenario, which often would include multiple ecological (...) subdistricts and thus partial isolation, was better suited for speciation than were isolated conditions. At the same time, many passages in Darwin's writings that apparently portrayed phyletic evolution exclusively (these including references to unconscious selection), actually applied to speciation as well, for phyletic change in a single district could constitute a local manifestation of a larger common-descent pattern. This generic use of "phyletic" change was reflected in Darwin's deployment of the unconscious selection analogy in his published writings as well as in his dispute with Moritz Wagner over the necessity of geographic isolation for speciation. We can thus understand Darwin's otherwise puzzling declaration in The Origin of Species that unconscious selection was 'more important' than the methodical approach. (shrink)

Research on thermal “black-body” radiation played an essential role in the origin of the quantum theory at the beginning of the twentieth century. This is a well-known fact, but historians of science up to now have not generally recognized that studies of radiant heat were also important in an earlier episode in the development of modern physics: the transition from caloric theory to thermodynamics. During the period 1830–50, many physicists were led by these studies to accept a “wave theory of (...) heat”, although this theory subsequently faded into obscurity. (shrink)

Are theories judged on the basis of empirical tests of their predictions, as proposed by Karl Popper and others, or are new theories adopted by younger scientists while old theories fade away when their advocates die, as Max Planck suggested? A famous historical episode, the rejection of steady state cosmology and the revival of the big bang cosmology following the 1965 discovery of the cosmic microwave background radiation, is examined to determine whether the scientific community followed Popper’s or Planck’s principle. (...) It is found that by 1975 almost all supporters of the steady state had either switched to the big bang or stopped publishing on cosmology. This case therefore seems to exemplify Popper’s principle, although it should be noted that two of the founders of steady state cosmology had strongly proclaimed their adherence to that principle. The case does not support the Popperian claim that successful novel predictions provide better evidence for a theory than deductions of known facts. (shrink)

Since philosophers generally agree that free will is understood partly by the relation it holds to moral responsibility, achieving a better understanding of free will requires that we have a clear idea of the sort of moral responsibility to which free will is thought to be connected. I argue that examining the substantive differences that exist between compatibilists and incompatibilists reveals a specific notion of moral responsibility that is best suited for philosophical debates regarding free will. Upon examination, it becomes (...) apparent that the primary substantive disputes between compatibilists and incompatibilists—as well as between libertarians and skeptics—have to do with the issue of whether retributivist reward or punishment is ever appropriate for certain kinds of agents. Drawing from this, I suggest that participants in the free will debate adopt a particular understanding of moral responsibility that can ground the propriety of retributivist justice. (shrink)

In his book The descent of man , Charles Darwin paid tribute to a trio of writers who offered naturalistic explanations of the origin of language. Darwin’s concurrence with these figures was limited, however, because each of them denied some aspect of his thesis that the evolution of language had been coeval with and essential to the emergence of humanity’s characteristic mental traits. Darwin first sketched out this thesis in his theoretical notebooks of the 1830s and then clarified his position (...) in Descent, where he argued that mind–language coevolution had occurred prior to the rise of distinct racial groups. He thus opposed the view of August Schleicher and Ernst Haeckel, who taught that speech had originated subsequent to the geographical and racial dispersion of humanity’s ancestors. As Darwin argued in Descent, this quasi-polygenetic version of coevolution was unable to explain primeval man’s initial dominance over rival ape-like populations. Drawing inspiration from British anthropologists, Darwin made the early development of language, hence mental monogenesis, central to his account of human evolution. (shrink)

SummaryIn the first part of the 19th century, geologists explained volcanoes, earthquakes and mountain-formation on the assumption that the earth has a large molten core underneath a very thin (25–50 mile) solid crust. This assumption was attacked on astronomical grounds by William Hopkins, who argued that the crust must be at least 800 miles thick, and on physical grounds by William Thomson, who showed that the earth as a whole behaves like a solid with high rigidity. Other participants in the (...) debate insisted that there is evidence for a fluid or plastic layer not far below the crust. It was also suggested that the interior of the earth is a supercritical fluid. By the end of the century many geologists had incorporated the doctrine of a completely solid earth into their theories. Acceptance of a relatively small liquid core, indicated by seismological research, was delayed for another two decades. (shrink)

The Fifth Annual Conference of the Hegel Society of Great Britain took place on September 15–16, 1983 in the delightful setting of St. Edmund Hall, Oxford. The theme of this year’s conference - “Hegel’s Dialectic” - was approached in a variety of ways by the contributors and provoked several lively and interesting discussions. The first paper of the conference was to have been given by Howard Williams, but unfortunately he had found his way to Pembroke College instead of St. Edmund (...) Hall and so was unable to begin the proceedings. The conference started therefore with a paper by John Llewelyn entitled “The Development of Dialectic from Kant to Hegel.”. (shrink)
