The monumental works of Bertrand Russell and Louis Couturat have set a firm pattern of interpretation which many follow in their approach to the Philosophy of Leibniz. In the Preface to the second edition of The Philosophy of Leibniz , Russell reaffirms his contention that “Leibniz’s philosophy was almost entirely derived from his logic”. He welcomes the support provided in Couturat’s La Logique de Leibniz . Russell remarks “No candid reader—can doubt that Leibniz’s metaphysic was derived by him from the (...) subject-predicate logic. This appears, for example, from the paper ‘Primae Veritates’ where all the main doctrines of the Monadology are deduced, with terse logical rigor from the premises; ‘Always therefore the predicate or consequent adheres in the subject or antecedent, and in this fact consists the nature of truth in general—But this is true in every affirmative truth, universal or singular, necessary or contingent’.” Referring further to Couturat, he points out that in his book the “Principle of Sufficient Reason” and “The Identity of Indiscernibles” are “expressly deduced—from the analytic character of all true propositions”. In short, Russell is contending that in formulating his metaphysics Leibniz used the rigorous methods of deductive logic and employed “models” drawn from logic to construct his “picture of reality”, i.e. his metaphysics.

There is little to indicate from, her circumstances that events would propel Helga Wanglie, an 86-year-old Minneapolis woman, into the center of public controversy. We know little of her life prior to the events that removed her from the world of conscious, sentient beings. By the time of her death on 4 July 1991, Mrs. Wanglie had become the focus of a nationwide public and professional debate on the rights of a patient in a persistent vegetative state to receive aggressive (...) medical treatment when such treatment is felt by the patient's doctors not to be in the patient's best interests.

In this overview article, we first explain what we take informal logic to be, discussing misconceptions and distinguishing our conception of it from competing ones; second, we briefly catalogue recent informal logic research, under 14 headings; third, we suggest four broad areas of problems and questions for future research; fourth, we describe current scholarly resources for informal logic; fifth, we discuss three implications of informal logic for philosophy in particular, and take note ofpractical consequences of a more general sort.

Assisted suicide is a tragic issue, one of those for which the tools of mere logic are inadequate and in which the power of the individual case is compelling and seductive but not necessarily clarifying. Meaningful dialogue is difficult. Persuasion is limited because the resolution of the issue, on a moral level, must be founded upon fundamental notions of what it means to be human, especially in the midst of suffering or disability or at the point of death.

He further argues that it is necessary to rethink traditional conceptions of argument, and to find a position that avoids the limitations of both the highly abstract approach of formal logic and the highly contextualized approaches of rhetoric and communication theory.".

What are the processes, from conception to adulthood, that enable a single cell to grow into a sentient adult? Neuroconstructivism is a pioneering 2 volume work that sets out a whole new framework for considering the complex topic of development, integrating data from cognitive studies, computational work, and neuroimaging.

This book is a cultural phenomenology of doing physics. It describes the ways physicists actually do their work--their motives, and their ways of making sense of the world--so that outsiders can understand it. Martin H. Krieger explains that physicists employ a small number of everyday notions to get at the world experimentally and conceptually.

We assessed the automaticity of spatial-numerical and spatial-musical associations by testing their intentionality and load sensitivity in a dual-task paradigm. In separate sessions, 16 healthy adults performed magnitude and pitch comparisons on sung numbers with variable pitch. Stimuli and response alternatives were identical, but the relevant stimulus attribute (pitch or number) differed between tasks. Concomitant tasks required retention of either color or location information. Results show that spatial associations of both magnitude and pitch are load sensitive and that the spatial (...) association for pitch is more powerful than that for magnitude. These findings argue against the automaticity of spatial mappings in either stimulus dimension. (shrink)
