Relevance logics are known to be sound and complete for relational semantics with a ternary accessibility relation. This paper investigates the problem of adequacy with respect to special kinds of dynamic semantics (i.e., proper relation algebras and relevant families of relations). We prove several soundness results here. We also prove the completeness of a certain positive fragment of R as well as of the first-degree fragment of relevance logics. These results show that some core ideas are shared between relevance logics (...) and relation algebras. Some details of certain incompleteness results, however, pinpoint where relevance logics and relation algebras diverge. To carry out these semantic investigations, we define a new tableaux formalization and new sequent calculi (with the single cut rule admissible) for various relevance logics. (shrink)

We confirm a conjecture, about neat embeddings of cylindric algebras, made in 1969 by J. D. Monk, and a later conjecture by Maddux about relation algebras obtained from cylindric algebras. These results in algebraic logic have the following consequence for predicate logic: for every finite cardinal α ≥ 3 there is a logically valid sentence X, in a first-order language L with equality and exactly one nonlogical binary relation symbol E, such that X contains only 3 variables (each of (...) which may occur arbitrarily many times), X has a proof containing exactly α + 1 variables, but X has no proof containing only α variables. This solves a problem posed by Tarski and Givant in 1987. (shrink)

Despite Vancil’s (1979) proclamation over twenty years ago that topoi have been abandoned in argument theory, this essay contends that topoi should have a vital role in contemporary argumentation theory. Four key areas are identified where topoi are (or can be) essential tools for argumentation: Locating argument, building argument, development of critical thinking, and argument pedagogy. As a result, teachers and students of argument can both benefit from a (re)discovery of topoi.

J. Angelo Corlett ABSTRACT: This is a paper on the philosophy of sport or the ethics of sport more specifically. It provides a critical assessment of a particular feminist approach to a specific issue in the ethics of sport with regard to what some feminist scholars refer to as the ‘sexualizing’ of women in sport...

C. A. J. Littlewood approaches Seneca's tragedies as Neronian literature rather than as reworkings of Attic drama, and emphasizes their place in the Roman world and in the Latin literary corpus. The Greek tragic myths are for Seneca mediated by non-dramatic Augustan literature. In literary terms Phaedra's desire, Hippolytus' innocence, and Hercules' ambivalent heroism look back through allusion to Roman elegy, pastoral, and epic respectively. Ethically, the artificiality of Senecan tragedy, the consciousness that its own dramatic worlds, events, and people (...) are literary constructs, responds to the contemporary Stoical dismissal of the public world as mere theatre.

In this monograph, authors J. Caleb Clanton and Kraig Martin argue that two classical approaches to moral grounding (natural law theory and divine command theory), while commonly opposed, can nevertheless be combined into a "third way" through precepts derived from the Stone-Campbell tradition. As such, this work represents an attempt to show the rich potential the Stone-Campbell tradition has in contributing to important, long-standing metaethical and philosophical questions.

According to the legend, Bishop Wilberforce at a meeting of the British Association for the Advancement of Science in Oxford on Saturday, June 30th, 1860, turned to Thomas Huxley, and asked him ``Is it on your grandfather's or your grandmother's side that you claim descent from a monkey''; whereupon Huxley delivered a devastating rebuke, thereby establishing the primacy of scientific truth over ecclesiastical obscurantism. Although the legend is historically untrue in almost every detail, its persistence suggests that it may nonetheless (...) be true in some deeper, mythical, sense. To explore this possibility the British Academy has invited Dr Janet Browne to be a neo-Huxley confronting Mr J.R. Lucas, as a neo-Wilberforce, with each reconsidering their earlier arguments.
