Jeffrey Collins’ new book aims to presents Locke’s views on religious toleration in the light of Thomas Hobbes’ political philosophy. At first blush, Hobbes seems an unusual choice as a point of co...

In Spandrels of Truth, Beall concisely presents and defends a modest, so-called dialetheic theory of transparent truth.

Consequence is at the heart of logic, and an account of consequence offers a vital tool in the evaluation of arguments. This text presents what the authors term as 'logical pluralism' arguing that the notion of logical consequence doesn't pin down one deductive consequence relation; it allows for many of them.

Orthologic is defined by weakening the axioms and rules of inference of the classical propositional calculus. The resulting Lindenbaum-Tarski quotient algebra is an orthoimplication algebra which generalizes the author's implication algebra. The associated order structure is a semi-orthomodular lattice. The theory of orthomodular lattices is obtained by adjoining a falsity symbol to the underlying orthologic or a least element to the orthoimplication algebra.

A good argument is one whose conclusions follow from its premises; its conclusions are consequences of its premises. But in what sense do conclusions follow from premises? What is it for a conclusion to be a consequence of premises? Those questions, in many respects, are at the heart of logic (as a philosophical discipline). Consider the following argument: 1. If we charge high fees for university, only the rich will enroll. We charge high fees for university. Therefore, only the rich (...) will enroll. There are many different things one can say about this argument, but many agree that if we do not equivocate (if the terms mean the same thing in the premises and the conclusion) then the argument is valid, that is, the conclusion follows deductively from the premises. This does not mean that the conclusion is true. Perhaps the premises are not true. However, if the premises are true, then the conclusion is also true, as a matter of logic. This entry is about the relation between premises and conclusions in valid arguments. (shrink)

The Liar paradox raises foundational questions about logic, language, and truth (and semantic notions in general). A simple Liar sentence like 'This sentence is false' appears to be both true and false if it is either true or false. For if the sentence is true, then what it says is the case; but what it says is that it is false, hence it must be false. On the other hand, if the statement is false, then it is true, since it (...) says (only) that it is false. -/- How, then, should we classify Liar sentences? Are they true or false? A natural suggestion would be that Liars are neither true nor false; that is, they fall into a category beyond truth and falsity. This solution might resolve the initial problem, but it beckons the Liar's revenge. A sentence that says of itself only that it is false or beyond truth and falsity will, in effect, bring back the initial problem. The Liar's revenge is a witness to the hydra-like nature of Liars: in dealing with one Liar you often bring about another. -/- JC Beall presents fourteen new essays and an extensive introduction, which examine the nature of the Liar paradox and its resistance to any attempt to solve it. Written by some of the world's leading experts in the field, the papers in this volume will be an important resource for those working in truth studies, philosophical logic, and philosophy of language, as well as those with an interest in formal semantics and metaphysics.

The two purposes of this essay. The general philosophical problem with most versions of social libertarianism and how this essay will proceed. The specific problem with liberty explained by a thought-experiment. The positive and abstract theory of interpersonal liberty-in-itself as ‘the absence of interpersonal initiated constraints on want-satisfaction’, for short ‘no initiated impositions’. The individualistic liberty-maximisation theory solves the problems of clashes, defences, and rectifications without entailing interpersonal utility comparisons or libertarian consequentialism. The practical implications of instantiating liberty: three rules (...) of liberty-in-practice, 1) initial ultimate control of one’s body, 2) initial ultimate control of one’s used resources, 3) consensual interpersonal interactions and resource transfers. These rules are economically efficient and maximise general want-satisfaction. Private property and legal remedies are additional practical institutional aspects, but to which ‘initiated impositions’ then apply prima facie. Libertarian law is often mistaken for complete libertarianism. Moral explanations are a separate issue. The three main moral theories imply libertarianism, but it can be morally posited independently of them. Critical rationalism and its application. No empirical or argumentative support for theories. An important ambiguity with ‘justification’. How the epistemology applies to the theory of liberty and its application but remains separable in principle. Conclusion: there are further published explanations but this should be enough to generate useful criticism. Appendix replying to some typical comments. (shrink)

In the late nineteenth century and the early decades of the twentieth thematic resemblances to the Roman elegists in Paulus Silentiarius were explained as the result of the poets' reliance on a common Hellenistic source – usually this was identified as the so-called ‘subjective Alexandrian love elegy’ – and this represented a departure from the views of earlier scholars such as Hertzberg and Postgate, who had maintained that Paulus knew and imitated the elegists. In recent years the pendulum has swung (...) back , and the prevailing opinion seems to be that the Roman elegists were known to Paulus. This is the view of, for instance, Giovanni Viansino in his edition of Paulus, of Elmar Schulz-Vanheyden in his important work on Propertius' relationship to Greek epigram, and of Hermann Beckby in his edition of the Greek Anthology. Recently, too, Gordon Williams has put forward a very strong case for earlier epigrammatists like Antipater and Crinagoras imitating the Augustan poets. (shrink)

The aim of this paper is to show the relationship between the normative outlook and political philoso- phy of traditional societies on the one hand, and the crises of governance and leadership in contemporary African Societies, particularly subSaharan states, on the other. Although there are quite some differences in the quality of leadership and governance among sub-Saharan African states because of the different political and economic circumstances, this part of the globe taken as a whole remains underdeveloped in terms of (...) having the will to institute and maintain stable polities with responsive, responsible and efficient governance.

Extensively classroom-tested, Possibilities and Paradox provides an accessible and carefully structured introduction to modal and many-valued logic. The authors cover the basic formal frameworks, enlivening the discussion of these different systems of logic by considering their philosophical motivations and implications. Easily accessible to students with no background in the subject, the text features innovative learning aids in each chapter, including exercises that provide hands-on experience, examples that demonstrate the application of concepts, and guides to further reading.

This paper examines the role of ideology in the emergence of the empirical sciences and the evolution of philosophy. It argues that the orientation of the religious ideology, Christianity, at the epistemological and ontological levels was very instrumental in the emergence of the empirical sciences in the area dominated by the culture of the Western (Latin) church. This claim is demonstrated by an analysis of the theoretical and methodological orientation of pre-Christian Europe, the epistemological and other philo- sophical values sponsored (...) by Christianity, as well as a comparative analysis of other cultural regions where such philosophical values did not exist. The paper then explores the evolution of philosophy after the emergence of the empirical sciences. It points out that the progress of philosophy along rational lines and the generation of knowledge thereof is not equivalent to embracing the method of the empirical sciences (scientism), but rather is a rediscovery of the rational attitude bearing in mind the context in which it has to operate.

The paper reviews a number of approaches for handling restricted quantification in relevant logic, and proposes a novel one. This proceeds by introducing a novel kind of enthymematic conditional.

Semantic and soritical paradoxes challenge entrenched, fundamental principles about language - principles about truth, denotation, quantification, and, among others, 'tolerance'. Study of the paradoxes helps us determine which logical principles are correct. So it is that they serve not only as a topic of philosophical inquiry but also as a constraint on such inquiry: they often dictate the semantic and logical limits of discourse in general. Sixteen specially written essays by leading figures in the field offer new thoughts and arguments (...) about the paradoxes. (shrink)

“We Need Not hesitate to translate the word eudaimonia by the English ‘happiness’”. So Burnet wrote in 1900, but the hardening consensus is that he was wrong. The differences between the two notions, it is now commonly supposed, are too many and too deep to think that happiness and eudaimonia are very closely related; and consequently “happiness”, the long-established conventional translation, will seriously mislead us in understanding the nature of Aristotelian eudaimonia.

Little, if anything, in Justin scholarship has been as controversial as the dating of the so-called Epitome of the Philippic History of Pompeius Trogus. Suggested dates have varied from the time of Antoninus Pius through the third century to the end of the fourth. The latter was proposed in 1988 by Sir Ronald Syme, but has in fact received little support in subsequent literature on Justin, which has tended to accept the earlier dating . An exception is T. D. Barnes, (...) who has voiced support for a later dating based on a linguistic parallel to Justin in the Historia Augusta. Barnes observes that Oscar Hey, author of the article ducatus in TLL , drew attention to the similarity between Justin 30.2.5 Agathocles regis lateri iunctus civitatem regebat, tribunatus et praefecturas et ducatus mulieres ordinabant and HA Heliog. 6.2 militaribus… praeposituris et legationibus et ducatibus venditis. Hey, he notes, refers at the head of that particular section of the article to Seeck's article on dux. Seeck had demonstrated—and this is now taken for granted by scholars—that from the time of Diocletian dux is used technically as a formal title, and, in drawing attention to the parallel between HA Heliog. 6.2 and Justin, Hey must have been intimating that Justin is, like the author of Heliog. 6.2, using ducatus as a formal title. He then seems to suggest that Hey was right and Justin is to be dated to at least some time after 260. (shrink)

Books 31 to 40 of Livy's history chart Rome's emergence as an imperial nation and the Romans tempestuous involvement with Greece, Macedonia and the near East in the opening decades of the second century BC; they are our most important source for Graeco-Roman relations in that century. Livy's dramatic narrative includes the Roman campaigns in Spain and against the Gallic tribes of Northern Italy; the flight of Hannibal from Carthage and his death in the East; the debate on the Oppian (...) law; and the Bacchanalian Episode.

In his very valuable study of generic patterns in ancient poetry Francis Cairns assigns Propertius 2.28, [Tib.] 3.10 , and Ovid Am. 2.13 to the genre Soteria, that is works of congratulation and thanksgiving on the recovery from illness of a friend, and he sees the resemblances between the poems as due to the elegists’ attempts to produce ‘dramatized’ examples of the genre, with the situation developing from the girl's illness at the beginning of the poem to her recovery at (...) the end , pp.153–7). Cairns's arguments and interpretation of the poems should, I feel, be scrutinized carefully, especially since his classification of the poems has been accepted recently without demur by at least one scholar , 118 and n.50).
