Hartry Field's revised logic for the theory of truth in his new book, Saving Truth from Paradox , seeking to preserve Tarski's T-scheme, does not admit a full theory of negation. In response, Crispin Wright proposed that the negation of a proposition is the proposition saying that some proposition inconsistent with the first is true. For this to work, we have to show that this proposition is entailed by any proposition incompatible with the first, that is, that it is the (...) weakest proposition incompatible with the proposition whose negation it should be. To show that his proposal gave a full intuitionist theory of negation, Wright appealed to two principles, about incompatibility and entailment, and using them Field formulated a paradox of validity (or more precisely, of inconsistency). The medieval mathematician, theologian and logician, Thomas Bradwardine, writing in the fourteenth century, proposed a solution to the paradoxes of truth which does not require any revision of logic. The key principle behind Bradwardine's solution is a pluralist doctrine of meaning, or signification, that propositions can mean more than they explicitly say. In particular, he proposed that signification is closed under entailment. In light of this, Bradwardine revised the truth-rules, in particular, refining the T-scheme, so that a proposition is true only if everything that it signifies obtains. Thereby, he was able to show that any proposition which signifies that it itself is false, also signifies that it is true, and consequently is false and not true. I show that Bradwardine's solution is also able to deal with Field's paradox and others of a similar nature. Hence Field's logical revisions are unnecessary to save truth from paradox. (shrink)

Thomas Bradwardine's solution to the semantic paradoxes, presented in his Insolubilia written in Oxford in the early 1320s, turns on two main principles: that a proposition is true only if things are wholly as it signifies; and that signification is closed under consequence. After exploring the background in Walter Burley's account of the signification of propositions, the question is considered of the extent to which Bradwardine's theory is compatible with the distribution of truth over conjunction, disjunction, negation and the conditional.

In line with the Principle of Uniform Solution, Graham Priest has challenged advocates like myself of the “multiple-meanings” solution to the paradoxes of truth and knowledge, due to the medieval logician Thomas Bradwardine, to extend this account to a similar solution to the paradoxes of denotation, such as Berry’s, König’s and Richard’s. I here rise to this challenge by showing how to adapt Bradwardine’s principles of truth and signification for propositions to corresponding principles of denotation and signification for (...) descriptive phrases, applying them to give a “multiple-meanings” solution to the denotational paradoxes.

Bradwardine’s solution to the the logical paradoxes depends on the idea that every sentence signifies many things, and its truth depends on things’ being wholly as it signifies. This idea is underpinned by his claim that a sentence signifies everything that follows from what it signifies. But the idea that signification is closed under entailment appears too strong, just as logical omniscience is unacceptable in the logic of knowledge. What is needed is a more restricted closure principle. A (...) clue can be found in speech act pluralism, whereby indirect speech reports are closed under intersubstitutivity of co-referential terms. The conclusion is that solving the semantic paradoxes does not require revision of logic, thus saving logic from paradox. (shrink)

The Bradwardine-Read multiple-meanings solution to paradoxes invented in 1320s and formally reconstructed and developed in 2000s is based on the so-called “closure principle for signification”, in particular, for sentential meaning. According to this principle, sentences are assumed to signify whatever they imply. As a consequence, paradoxical sentences are proved to signify their own truth and thereby are reduced to simply false self-contradictions. One of the problems of this solution to paradoxes is that the closure principle over-generates if (...) sentences are closed under unrestricted entailment. The present proposal will introduce a restriction based on what will be called the “dynamic closure principle”: sentential meaning will be regarded as closed under the inference steps performed in the (actual or optimal) process of evaluating the respective sentence’s truth-value.

Jean Buridan has offered a solution to the Liar Paradox, i.e. to the problem of assigning a truth-value to the sentence ‘What I am saying is false’. It has been argued that either this solution is ad hoc since it would only apply to self-referencing sentences [Read, S. 2002. ‘The Liar Paradox from John Buridan back to Thomas Bradwardine’, Vivarium, 40 , 189–218] or else it weakens his theory of truth, making his ‘a logic without truth’ [Klima, G. 2008. ‘Logic (...) without truth: Buridan on the Liar’, in S. Rahman, T. Tulenheimo and E. Genot, Unity, Truth and the Liar: The Modern Relevance of Medieval Solutions to the Liar Paradox, Berlin: Springer, 87–112 ; Dutilh Novaes, C. 2011. ‘Lessons on truth from mediaeval solutions to the Liar Paradox’, The Philosophical Quarterly, 61 , 58–78]. Against , I will argue that Buridan's solution by means of truth by supposition does not involve new principles. Self-referential sentences force us to handle supposition more carefully, which does not warrant the accusation of adhoccery. I will also argue, against (2), that it is exaggerated to assert that this solution leads to a ‘weakened’ theory of truth, since it is consistent with other passages of the Sophismata, which only gives necessary conditions for the truth of affirmative propositions, but sufficient conditions for falsity.

Swedenborg's Principles of Usefulness presents a possibly unsuspected historical undercurrent that further evidences Emanuel Swedenborg's pervasive influence on a whole host of historical figures-from poets and artists to philosophers and statesmen-whose contributions to the evolution of self and society have resonated throughout time and into the present. Besides having an impact on individual thinkers, Swedenborg's ideas worked their way into the various social reform traditions that vitalized the American landscape during the nineteenth and early-twentieth centuries.

The fourteenth-century thinker Thomas Bradwardine is well known in both the history of science and the history of theology. The first of the Merton Calculators (mathematical physicists) and passionate defender of the Augustinian doctrine of salvation through grace alone, he was briefly archbishop of Canterbury before succumbing to the Black Death in 1349. This new edition of his Insolubilia, made from all thirteen known manuscripts, shows that he was also a logician of the first rank. The edition is accompanied by (...) a full English translation. In the treatise, Bradwardine considers and rejects the theories of his contemporaries about the logical puzzles known as 'insolubles,' and sets out his own solution at length and in detail. In a substantial introduction, Stephen Read describes Bradwardine's analysis, compares it with other more recent theories, and places it in its historical context. The text is accompanied by three appendices, the first of which is an extra chapter found in two manuscripts (and partly in a third) that appears to contain further thoughts by Bradwardine himself. The second contains an extract from Ralph Strode's Insolubilia, composed in the 1360s, repeating and enlarging on Bradwardine's text; and the third consists of an anonymous text that applies Bradwardine's solution to a succession of different insolubles"--P.

Expanding on the recent research of Stephen Read and Catarina Dutilh Novaes concerning Thomas Bradwardine's theory of truth, the present paper makes an effort to analyse the Currian conditional in terms of the so-called ?Bradwardine principle?, i.e. the principle that meaning is closed under entailment. Based upon two possible applications of this approach, alternative solutions to the issues of semantic pathology and trivialisation of deductive systems are presented.

The principle of indifference is supposed to suffice for the rational assignation of probabilities to possibilities. Bertrand advances a probability problem, now known as his paradox, to which the principle is supposed to apply; yet, just because the problem is ill‐posed in a technical sense, applying it leads to a contradiction. Examining an ambiguity in the notion of an ill‐posed problem shows that there are precisely two strategies for resolving the paradox: the distinction strategy and the well‐posing strategy. (...) The main contenders for resolving the paradox, Marinoff and Jaynes, offer solutions which exemplify these two strategies. I show that Marinoff’s attempt at the distinction strategy fails, and I offer a general refutation of this strategy. The situation for the well‐posing strategy is more complex. Careful formulation of the paradox within measure theory shows that one of Bertrand’s original three options can be ruled out but also shows that piecemeal attempts at the well‐posing strategy will not succeed. What is required is an appeal to general principle. I show that Jaynes’s use of such a principle, the symmetry requirement, fails to resolve the paradox; that a notion of metaindifference also fails; and that, while the well‐posing strategy may not be conclusively refutable, there is no reason to think that it can succeed. So the current situation is this. The failure of Marinoff’s and Jaynes’s solutions means that the paradox remains unresolved, and of the only two strategies for resolution, one is refuted and we have no reason to think the other will succeed. Consequently, Bertrand’s paradox continues to stand in refutation of the principle of indifference. (shrink)

It is well known that Husserl considered phenomenology to be First Philosophy—the ultimate science. For Husserl, this means that phenomenology must clarify the ultimate phenomenological-epistemological principle that leads to ultimate elucidation. But what is this ultimate principle and what does ultimate elucidation mean? It is the aim of this paper to answer these questions. In section 2, we shall discuss what role Husserl’s principle of all principles can play in the quest for ultimate elucidation and what it (...) means for a principle to be ultimately elucidating and ultimately elucidated. We will see that the Husserlian thesis that originary presentive intuitions are an immediate and the ultimate source of justification qualifies as the ultimate epistemological principle. (shrink)

The early David Lewis was a staunch critic of the Truthmaker Principle. To endorse the principle, he argued, is to accept that states of affairs are truthmakers for contingent predications. But states of affairs violate Hume's prohibition of necessary connections between distinct existences. So Lewis offered to replace the Truthmaker Principle with the weaker principle that ‘truth supervenes upon being’. This chapter argues that even this principle violates Hume's prohibition. Later Lewis came to ‘withdraw’ his (...) doubts about the Truthmaker Principle, invoking counterpart theory to show how it is possible to respect the principle whilst admitting only things that do not violate Hume's prohibition. What this really reveals is that the Truthmaker Principle is no explanatory advance on the supervenience principle. Extending Lewis's use of counterpart theory also allows us to explain away the necessary connections that threatened to undermine his earlier statements of supervenience. (shrink)

In this essay, “The Principle of Autonomy in Kant’s Moral Theory: Its Rise and Fall,” Pauline Kleingeld notes that Kant’s Principle of Autonomy, which played a central role in both the Groundwork for the Metaphysics of Morals and the Critique of Practical Reason, disappeared by the time of the Metaphysics of Morals. She argues that its disappearance is due to significant changes in Kant’s political philosophy. The Principle of Autonomy states that one ought to act as if (...) one were giving universal laws through one’s maxims. The criterion of just legislation that Kant accepted in the mid-1780s does not require any actual consent on the part of the citizens—genuine universality is sufficient for a law to be just. Hence, at that time, Kant could indeed explicate the criterion governing the moral permissibility of one’s maxims by drawing an analogy with the criterion governing the justice of political laws. In the Metaphysics of Morals and in other works in the 1790s, however, he added the further condition that laws must be given with the consent of the citizens. With this further condition, the moral criterion was no longer fully analogous to the criterion for political laws being just. Accordingly, Kleingeld argues, Kant dropped the Principle of Autonomy, which was firmly based on that analogy. (shrink)

The Pauli exclusion principle is interpreted using a geometrical theory of electrons. Spin and spatial motion are described together in an eight dimensional spinor coordinate space. The field equation derives from the assumption of conformal waves. The Dirac wave function is a gradient of the scalar wave in spinor space. Electromagnetic and gravitational interactions are mediated by conformal transformations. An electron may be followed through a sequence of creation and annihilation processes. Two electrons are branches of a single particle. (...) Each satisfies a Dirac equation, but together they are a solution of the curvature condition. As two so identified electrons approach each other, the exclusion principle develops from the boundary conditions in spinor space. The gradient motion does not allow the particles to overlap. Since the spinor-gradient of the scalar wave function is odd in the coordinates, the sign of the wave function must change at the electron-electron boundary. The exclusion principle becomes geometry intrinsic and all electrons are combined into one field. Further applications are proposed including the possibility of improved numerical calculations in atomic and molecular systems. There also may be extensions to nuclear or particle physics. Implications are expected for the properties of rotating objects in a gravitational field. (shrink)

Adherents of Ockham’s fundamental razor contend that considerations of ontological parsimony pertain primarily to fundamental objects. Derivative objects, on the other hand, are thought to be quite unobjectionable. One way to understand the fundamental vs. derivative distinction is in terms of the Aristotelian distinction between ontologically independent and dependent objects. In this paper I will defend the thesis that every natural number greater than 0 is an ontologically dependent object thereby exempting the natural numbers from Ockham’s fundamental razor.

Stephen Read (2002, 2006) has recently discussed Bradwardine's theory of truth and defended it as an appropriate way to treat paradoxes such as the liar. In this paper, I discuss Read's formalisation of Bradwardine's theory of truth and provide a class of models for this theory. The models facilitate comparison of Bradwardine's theory with contemporary theories of truth.

This article presents an account of temporal understanding in Mandarin Chinese. Aspectual, lexical, and adverbial information, and pragmatic principles all contribute to the interpretation of temporal location. Aspectual viewpoint and situation type give information in the absence of explicit temporal forms. The main, default pattern of interpretation is deictic.

Paul Ramsey has argued that the rule of double effect is morally significant because of the existence of indeterminate choices between incommensurable values. I interpret his argument as the following disjunctive syllogism.

The second does not work, so we are left with the first. I respond, first, that this argument commits the fallacy of bifurcation (...) and second, that for all Ramsey has shown, and surprisingly, a commensurate reason principle can deal with indeterminate choices.

According to Locke’s Principle, material objects are identical if and only if they are of the same kind and once occupy the same place at the same time.

In this paper, I take issue with two arguments that have been offered in support of this claim by arguing (i) (...) that we can have knowledge of past whereabouts, and so verify the right hand side of Locke’s Principle, without having to assess concrete identity claims first; (ii) that even under conditions of incomplete knowledge of past whereabouts we can use Locke’s Principle to decide concrete identity problems.

Summary In establishing what he called the metaphysics of science , the French naturalist Buffon was confronted with the problem of situating the place occupied by man in the natural world, a problem which ultimately depended on discerning his true nature. The paradox of Descartes' dualism offered various solutions — the extremes being, either to condemn man's material nature as corrupted in order to exalt his spiritual nature as a moral being, as Pascal had done, or to reduce man's pretended (...) spiritual nature to nothing more than a manifestation of his material organization, the solution of La Mettrie. Buffon could accept neither, proves man's duality, and proceeds to establish his gnoseological principle on his critique of these two radical solutions. (shrink)

Most recently Smart and Thébault revived an almost forgotten debate between Katzav and Ellis on the compatibility of Hamilton’s Principle with Dispositional Essentialism. Katzav’s arguments inter alia aim to show that HP presupposes a kind of metaphysical contingency which is at odds with the basic tenets of DE, and offers explanations of a different type and direction from those given by DE. In this paper I argue that though dispositional essentialists might adequately respond to these arguments, the question about (...) the compatibility of HP with DE has not been answered yet; therefore, dispositional essentialists have not yet provided an illuminating DE-friendly metaphysical account of HP.

Augustine advances the view that morally devout interpreters of a Biblical text, such as the Psalter, can each advance contradictory interpretations of the very same portion of the text and yet both interpretations can be true. But the moral character of the interpreter is paramount in weighing the validity of the interpretation. I explore this hermeneutical principle Augustine advances with Donald Davidson’s secular “Principle of Charity”.

Reid's principle of credulity may be interpreted as equivalent to a principle of charity, due to the nature of three beliefs it implies concerning the interlocutors, which are held by the person who attempts to acquire their language: They are telling truth in the sense that they are saying what they really think, perceive, feel, believe; they are veracious in the sense that what they say is objectively true; they use language consistently. This interpretation relies on Reid's straightforward (...) remarks on his principle of credulity and on his view of two related correspondences: One correspondence is between the principle of credulity and the principle of veracity. The other is between these two principles and the principles that create the ‘language of nature’ and guide us in our efforts to unravel it. (shrink)

Mach's principle is discussed as a fundamental statement on kinematics, and an apparent contradiction is identified in the Lorentz-Minkowski form of the inertial metric. To resolve the incompatibility, length is redefined so that the speed of light is a field-dependent variable, although still constant for all inertial observers at a point in space-time. Gravitational theories with variableG are considered, and it is shown that a redefinition of length and time results in constantG and variablec.

The Institute of Medicine (IOM) Committee on Ethical Considerations for Revisions to DHHS Regulations for Protection of Prisoners Involved in Research published its report in 2006. It was charged with developing an ethical framework for the conduct of research with prisoners and identifying the safeguards and conditions necessary to ensure that research with prisoners is conducted ethically. The recommendations contained in the IOM report differ from current European regulations in several ways, some being more restrictive and some less so. For (...) example, the IOM report suggests limiting the percentage of prisoners that should be involved in a biomedical study to 50%, a limit that does not exist in Europe. However, the report does not specifically advise against research without a direct benefit to an individual prisoner: the European regulations are more restrictive than the IOM committee recommendations in this respect. The definition of minimal risk varies, as well as the proposed role of the minimal risk requirement and of the principle of subsidiarity (research that can only be done effectively in prisons). The IOM report proposes a number of thoughtful suggestions, which it would be beneficial to implement everywhere, such as registers of research on prisoners. The European regulations offer pragmatic solutions to several thorny issues. In summary, the IOM committee report represents an admirable effort to tackle the present inconsistencies and deficiencies of federal regulations in the US on research on prisoners (45 CFR 46 Subpart C). Nonetheless, before acting on the recommendations, US regulators might consider revisiting international guidelines such as those published by the Council for International Organizations of Medical Science (CIOMS) and the Declaration of Helsinki.

Skene and Parker1 raise a number of concerns about religious doctrine unduly influencing law and public policy through amicus curiae contributions to civil litigations or direct lobbying of politicians. Oakley2 picks this up in the same issue with an emphasis on the Roman Catholic Church’s interest in preventing the destruction of embryos for embryonic stem cell research. Skene, Parker, and Oakley seem to be concerned mostly with religious views having undue influence on public policy. My concern is the negative effect (...) that such Church influenced public policy may have on the progress of the biomedical research that is itself foundational to the debate. Oakley seems to be particularly incensed that, as he puts it: “Those who support a total ban on embryonic stem cell research sometimes talk as if theirs are the only views based on moral principle”.2 What seems to be at issue here though are not the moral principles of the sanctity and dignity of human life, but the application of those moral principles to biomedical research.The Roman Catholic Church has historically defended the sanctity and dignity of human life to varying degrees at different times. Human life for much of the past 2000 years was defined by the Church as the presence of the soul, which was thought at different times to appear at various different stages during development. Only recently, with the advent of modern biology, has the Roman Catholic Church shifted its position to claim that the fertilised egg also qualifies as the right sort of human life.3 It should be noted that this doctrinal change was fundamentally driven by developments in our understanding of embryology and not the process of ensoulment.The Church’s current position on the embryo is thus based not solely on Church doctrine but also on ….

The central feature of modern liberal political morality is the principle of equal respect for persons. According to Ronald Dworkin, governments have an obligation to treat each person as an equal, with equal concern and respect. In distributive contexts, this principle stipulates that each individual is entitled to an “equal” share of social resources, where equal is a function of what is required by the abstract principle of equal concern and respect. For Dworkin, this requirement means that (...) liberal justice is fundamentally concerned with treating peopleas equalsand notequally. By treating someone as an equal he supposes that government must treat each of its citizens with equal dignity, regarding her as an individual with a standing interest in leading a truly good life. By contrast, to treat someone equally, according to Dworkin, “...requires that government treat all those in its chargeequallyin the distribution of some resource or opportunity....” To treat persons as equals, that is, with equal concern and respect, is to arrange for all individuals to receive those material goods and opportunities that make living a good life possible. For my purposes, I will assume that treating people as equals is the constitutive feature of liberal equality. (shrink)

BackgroundThe proper and ethical inclusion of PWLHIV and their young children in research is paramount to ensure valid evidence is generated to optimize treatment and care. Little empirical data exists to inform ethical considerations deemed most critical to these populations. Our study aimed to systematically review the empiric literature regarding ethical considerations for research participation of PWLHIV and their young children.MethodsWe conducted this systematic review in partnership with a medical librarian. A search strategy was designed and performed within the following (...) electronic databases: Ovid MEDLINE, Embase and CINAHL. We screened titles and abstracts using the following inclusion criteria: (1) a study population of PWLHIV or children under 5 years of age; and (2) collection of qualitative or quantitative data regarding ethics of research participation. Excluded were reviews, commentaries, policy statements, clinical care-related ethics concerns, abstracts, case studies, or studies unrelated to HIV research. Studies were appraised for quality, data were extracted, and studies were qualitatively analyzed using a principle-based ethical framework within the Belmont Report.ResultsOf the 7470 titles identified, 538 full-text articles were reviewed for eligibility and only three articles met full criteria for inclusion within this review. While we allowed for inclusion of studies involving young children born to mothers with HIV, only articles focused on PWLHIV were identified. Within the results of these studies, four themes emerged: (1) adequacy of informed consent; (2) consideration of paternal involvement; (3) balancing risks; and (4) access to research and treatment. A strength of this review is that it included perspectives of international research investigators, community leaders, and male partners. However, only two studies collected empiric data from PWLHIV regarding their experiences participating in researchConclusionResearchers and funding agencies should be aware of these considerations and appreciate the value of and critical need for formative research to ensure clinical trials involving PWLHIV promote ethical, well-informed research participation and, ultimately, improve care outcomes. More research is needed to create a comprehensive ethical framework for researchers when conducting studies with PWLHIV. (shrink)
