In this paper a formalized logic of propositions, PA1, is presented. It is proven consistent and its relationships to traditional logic, to PM ([15]), to subjunctive (including contrary-to-fact) implication and to the “paradoxes” of material and strict implication are developed. Apart from any intrinsic merit it possesses, its chief significance lies in demonstrating the feasibility of a general logic containing theprinciple of subjunctive contrariety, i.e., the principle that ‘Ifpwere true thenqwould be true’ and ‘Ifpwere true thenqwould be false’ are incompatible.

We give a tensor formulation of synchronization transformations within special relativity in order to bridge the gap between some philosophical discussions (e.g., by Grünbaum and Winnie) and the analyses given by physicists (e.g., Møller). As an application, we discuss a physical interpretation of the duality between covariant and contravariant indices in the tensor formulation.

It is argued that the Tractatus Project of Logical Atomism, in which the world is conceived of as the totality of independent atomic facts, can usefully be understood by conceiving of each fact as a bit in logical space. Wittgenstein himself thinks in terms of logical space. His elementary propositions, which express atomic facts, are interpreted as tuples of co-ordinates which specify the location of a bit in logical space. He says that signs for elementary propositions are arrangements of names. (...) Here, the names are understood as numerical symbols specifying coordinates. It is argued that, using this approach, the so-called colour-exclusion problem, which was Wittgensteins reason for abandoning the Tractatus, is in fact soluble. However, if logical space is a continuum then some coordinates will need to be expressed by numerical symbols that are infinite in size. How is this to be understood in Tractatus terms? It is shown that, in the Tractatus, Wittgenstein did recognise the possibility of infinite propositions and sentences expressing them. At first sight his approach to infinite sentences, and the approach of the present paper, seem to differ, but it is argued that the difference is superficial. Finally, we address the question of whether Logical Atomism is viable and this raises issues concerning its relationship to natural science. (shrink)

This essay explores some of the dogmatic challenges involved in developing a distinctively evangelical account of the doctrine of theosis, that is, humanity’s participation in the life of God. After offering some preliminary clarifications regarding the terminology of theosis, the paper sketches in broad strokes how an account of theosis might take shape within the structures of evangelical theology. David Bebbington’s famous evangelical quadrilateral— biblicism, crucicentrism, conversionism, and activism—serves as the basic framework (Bebbington 1989: 1-19). It will be argued that (...) evangelical theology can accommodate a version of theosis within this structure, but that evangelicals’ understanding of these categories may require some ‘flexing’ in order to make room for a more Christocentric and participatory conceptualization of redemption, one that culminates in the beatific vision of the redeemed when ‘God will be all in all’ (1 Cor 15:28). The final section of the paper points to a pair of important figures who may serve as resources for an evangelical retrieval of theosis. (shrink)

Much speculation on the sources of Duhem's historical interests fails to account for the major shifts in these interests: neither his belief in the continuous development of physics nor his Catholicism, when his Church was encouraging the study of generally Aristotelian scholastic thought, led to any interest in mediaeval science before 1904. Equally, his own claim that he was merely testing his views on the nature of physical theory is easily squared only with earlier work with no trace of mediaeval (...) science. Behind this discontinuity lies a major crisis. Though not a positivist, Duhem had based all his work on assumptions acceptable to positivists. One of these, the sterility of the Middle Ages, was refuted by his chance discovery of evidence of genuine mediaeval science in the autumn of 1903, but that left the doctrine of scholastic sterility intact.

This concise, lively introduction to ancient Greek philosophy will help beginning students of both classical studies and philosophy get their bearings within an important yet complex array of names, schools, and ideas. The book illuminates the key period from the sixth to the third century BC, looking at the ideas that engaged the Greeks, in particular those of the Presocratics, the Sophists, Socrates, Plato, Aristotle, and the earliest Hellenistic philosophers. After chronologically mapping the main figures and their interconnections, _Introducing Greek (...) Philosophy_ focuses on themes especially relevant to philosophy today, including the origins of the universe and its mathematical structures; divine creation versus evolution and natural law; probability theory and the criteria for truth; political debates on democracy, citizen rights, and state obligations; and finally ethics, happiness, and the best way to live.

This article looks at the vigorous questioning of the immortality of the soul during the early modern period. It offers an account of some significant aspects of the philosophy of the soul in the early modern period and of its transformation across that period. It proposes a thesis about the place of the soul in early modern conceptions of what it meant to be a human animal and traces the contribution of the early modern philosophy of the soul to the (...) enlightened science of human nature.

In Russell's Problems of Philosophy (PP), acquaintance is the basis of thought and also the basis of empirical knowledge. Thought is based on acquaintance, in that a thinker has to be acquainted with the basic constituents of his thoughts. Empirical knowledge is based on acquaintance, in that acquaintance is involved in perception, and perception is the ultimate source of all empirical knowledge.
