This is the first full-length biography of John Langshaw Austin (1911–60). The opening four chapters outline his origins, childhood, schooling, and time as an undergraduate, while the next four examine his early career in professional philosophy, looking at the influence of Oxford Realism, Logical Positivism, Pragmatism, and the later Wittgenstein. The central twelve chapters then explore Austin’s wartime career in British Intelligence. The first three examine the contributions he made to the campaigns in North Africa; the next seven the seminal (...) role he played in ensuring the outstanding accuracy of the D-Day Intelligence; while the final two explore his contributions to Arnhem, the Ardennes, and the post-war administration of Germany. The last main section of the book then outlines and assesses Austin’s contributions to post-war Oxford Ordinary Language Philosophy. The first three chapters discuss the impact on Oxford philosophy of the cultural atmosphere of post-war Britain and the later Wittgenstein’s ideas. The next four look at Austin’s influence on post-war Oxford, particularly his Saturday morning discussion group and his perception lectures. The next five chapters concentrate on America’s influence on Austin and vice versa, paying particular attention to Austin’s work on speech-acts and his semesters in Harvard and Berkeley. The final two chapters examine Austin’s declining influence in Oxford, and his tragically premature death. (shrink)

ArgumentIn the United States, scientific knowledge is brought before the courts by way of testimony – the testimony of scientific experts. We argue that this expertise is best understoodfirstas related to the quality of the underlying scienceand thenin terms of who delivers it. Bloodstain pattern analysis (BPA), a contemporary forensic science, serves as the vaulting point for our exploration of objectivity as a metric for the quality of a science in judicial contexts. We argue that BPA fails to meet the (...) minimal standard set by Helen Longino’s social-procedural account of objectivity (1990, 2002). In light of some pressing issues for social-procedural accounts, we offer an infrastructural account of objectivity. This account offers what amounts to a friendly amendment to Longino’s account and adds to the ways in which we might analyze social-procedural objectivity. Finally, we address an issue that is pressing in the legal context: given that scientific knowledge is delivered by individuals, not communities, at least in U.S. courts, we (may) need a way to evaluate individual scientific and epistemic agents. We suggest a means for making this evaluation that is derived from our infrastructural account of objectivity. (shrink)

The standard deduction theorem or introduction rule for implication, for classical logic is also valid for intuitionistic logic, but just as with predicate logic, other rules of inference have to be restricted if the theorem is to hold for weaker implicational logics.In this paper we look in detail at special cases of the Gentzen rule for and show that various subsets of these in effect constitute deduction theorems determining all the theorems of many well known as well as not well (...) known implicational logics. In particular systems of rules are given which are equivalent to the relevance logics E,R, T, P-W and P-W-I. (shrink)

This paper will survey and assess the ways in which moral thinkers in the early modern tradition of casuistry considered a range of cases of conscience (casus conscientiae) relating to lying, deception, and witholding the truth. Arguing that the position of the casuists has been unjustly maligned — not least by Pascal's brillant yet partizan Les Proviniciales — casuistical theories of lying and simulation will be placed in a broad intellectual context which will examine attihules to mendacity among early modern (...) medical writers, political theorists, anbl philosophers. Contrasting casuistical theoriessuch as equivocation and mental reservation with the approach to lying of other early modern writers, the lecture will advancfcahe view that the casuists promulgated a conceptual outlook on the differences betweefc lying and deception which is of inherent interest, and which helps to clarify some of the salient issues that attend a philosophical account of lying.

The first system of intersection types, Coppo and Dezani [3], extended simple types to include intersections and added intersection introduction and elimination rules (( $\wedge$ I) and ( $\wedge$ E)) to the type assignment system. The major advantage of these new types was that they were invariant under β-equality, later work by Barendregt, Coppo and Dezani [1], extended this to include an (η) rule which gave types invariant under βη-reduction. Urzyczyn proved in [6] that for both these systems it is (...) undecidable whether a given intersection type is empty. Kurata and Takahashi however have shown in [5] that this emptiness problem is decidable for the sytem including (η), but without ( $\wedge$ I). The aim of this paper is to classify intersection type systems lacking some of ( $\wedge$ I), ( $\wedge$ E) and (η), into equivalence classes according to their strength in typing λ-terms and also according to their strength in possessing inhabitants. This classification is used in a later paper to extend the above (un)decidability results to two of the five inhabitation-equivalence classes. This later paper also shows that the systems in two more of these classes have decidable inhabitation problems and develops algorithms to find such inhabitants. (shrink)

My hope has been to persuade readers that Hobbes's mighty thought experiment of the state of nature distorts our conceptual learning because it ignores the second morality. Instead, it inflates the first morality as the whole of morality. This inflation arises from Hobbes's exclusive preoccupation with universalizable reason. As important as universal reason undeniably is, it does not encompass the whole of moral reality. To suppose that it does is to distort moral reality. Like so many Enlightenment figures, Hobbes would (...) have political theory be more like logic than life.To refer once again to the Enlightenment allows me to observe that the drive to universality through reason is a distinctive feature of European civilization. To proceed along this line might lead to the conclusion that the pursuit of the universal is a cultural artifact. It is itself culturally relative. I am in no position to argue that point here at the end of the day, but did not the universal criteria propounded by the Enlightenment prove serviceable in the justification of European imperialism? By the universal standards of the Enlightenment only Europe was civilized.Reason is often a weapon. Alasdair MacIntyre has termed the search for rationality in moral philosophy a masquerade. MacIntyre sees the quest for rationality to be a quest for authority. He cites John Maynard Keynes's observations that “in practice, victory [in moral argument] was with those who could speak with the greatest appearance of clear, undoubting conviction and could best use the accents of infallibility.” Rationality is a weapon. “In moral argument the apparent assertion of principles functions as a mask for expressions of personal preference.” Alasdair MacIntyre, After Virtue, 2nd ed. (London: Duckworth, 1985), pp. 9, 17, and 19. Seasoned participants in academic conferences and learned seminars realize the intensity of involvement in what Sheila Ruth has called “The Hunt.”Sheila Ruth, “Methodocracy, Misogyny, and Bad Faith,” Men's Studies Modified, Dale Spender (ed.) (Oxford: Pergamon, 1981), p. 48. The speaker is the quarry. The others, the auditors are the hunters. Some are accomplished, others are not yet blooded. They wait for the weak point. It's blood. They attack. The inexperienced hunters are enthusiastic. The seasoned hunters take their time. The quarry defends. An arbitrary time limit ends the combat, and after tea it is someone else's turn. Can anyone say that this is the best way to search out alternatives, weigh experience, assess implications, evaluate assertions? My title “The Government of Reason” is deliberately ambiguous. On the one hand it might mean governing according to the light of reason. This was, of course, the avowed aim of the Enlightenment. The conduct of political life would follow the bright line of reason. On the other hand, the title could mean governing reason, taking control of reason and using it as a weapon. Here we may be forgiven for thinking of Michel Foucault on the use of knowledge as power. The ambiguity of the title is meant to reflect the ambiguity of reality where both alternatives have occurred. Only half of the moral realm has been made the subject of political theory. (shrink)

This study compared the family characteristics, victimization histories, and number of perpetration offenses of juvenile offenders who admitted to having had sex with animals to juvenile offenders who did not. The study found that 96% of the juveniles who had engaged in sex with nonhuman animals also admitted to sex offenses against humans and reported more offenses against humans than other sex offenders their same age and race. Those juveniles who had engaged in sex with animals were similar to other (...) sex offenders in that they also came from families with less affirming and more incendiary communication, lower attachment, less adaptability, and less positive environments. Those juveniles who had engaged in sex with animals reported victimization histories with more emotional abuse and neglect and a higher number of victimization events than other offenders. This would seem to indicate that sex with animals may be an important indicator of potential or co-occurring sex offenses against humans and may be a sign of severe family dysfunction and abuse that should be addressed in the arenas of psychological intervention, juvenile justice programs, and public policy.

The passing on of information to GPs by genito-urinary doctors is to be encouraged but is not always possible and ultimately the patient's wishes and confidentiality must be respected if sexually transmitted diseases and HIV infection are to be controlled. Infected health-care workers should seek counselling and medical support and clear guidelines from professional organisations which are in existence. However, they will only do so if strict confidentiality is maintained and assurance about future employment can be given.

The classical relativistic theory is developed of electric and magnetic fields in terms of boost and rotation generators, respectively, of the Lorentz group of space-time. This development shows that Minkowski geometry requires that there be threestates of polarization of radiation in free space. The magnetic components in a circular basis are right and left circular and longitudinal. The longitudinal component is real and physical, and proportional to one of the three, nonzero, rotation generators of the Lorentz group. The longitudinal electric (...) component is pure imaginary, and proportional to one of the three boost generators. These theoretical arguments conform with experimental data from the Planck radiation law and from magnetic effects of light such as the inverse Faraday effect. (shrink)

The relation is developed between rotation generators of the Lorentz group and the magnetic fields of free-space electromagnetism. Using these classical relations, it is shown that in the quantum field theory there exists a longitudinal photomagneton, a quantized magnetic flux density operator which is directly proportional to the photon spin angular momentum. Commutation relations are given in the quantum field between the longitudinal photomagneton and the usual transverse magnetic components of quantized electromagnetism. The longitudinal component is phase free, but the (...) transverse components are phase dependent. All three components can magnetize material in general, but only the transverse components contribute to Planck's law. The photon therefore has three, not two, relativistically invariant degrees of polarization, an axial, longitudinal, polarization, and the usual right and left circular transverse polarizations. Since the longitudinal polarization is axial, it is a phase- free magnetic field. (shrink)

In positive logic the negation of a propositionA is defined byA X whereX is some fixed proposition. A number of standard properties of negation, includingreductio ad absurdum, can then be proved, but not the law of noncontradiction so that this forms a paraconsistent logic. Various stronger paraconsistent logics are then generated by putting in particular propositions forX. These propositions range from true through contingent to false.
