The nature of necessary truth was a central concern of Ludwig Wittgenstein. It was present in his early reflections on logic, a core motif of the Tractatus, and a topic he returned to over and again in his reflections on language, logic, and mathematics. This chapter explores the aspects of Wittgenstein's account of necessity and apriority, beginning with the Tractatus, where many of his core insights received their first expression. It discusses two more contemporary accounts of these topics: conceptual role (...) semantic theories of the a priori, and the arguments for divorcing apriority from necessity. Necessity in the Tractatus appears at two locations. One is at the level of individual elementary propositions. The other is at the level of the inferential connections between propositions. The chapter looks at the Tractatus theory of the proposition. Wittgenstein saw an important difference between the formulations of the rules of grammar and descriptions of states of affairs.

Wittgenstein's Tractatus carefully distinguished the concept all from\nthe notion of a truth-function, and thereby from the quantifiers.\nI argue that Wittgenstein's rationale for this distinction is lost\nunless propositional functions are understood within the context\nof his picture theory of the proposition. Using a model Tractatus\nlanguage, I show how there are two distinct forms of generality implicit\nin quantified Tractatus propositions. Although the explanation given\nin the Tractatus for this distinction is ultimately flawed, the distinction\nitself is a genuine one, and the forms of generality that (...) Wittgenstein\nindicated can be seen in the quantified sentences of contemporary\nlogic. (shrink)

Analyticity, or the 'analytic/synthetic' distinction is one of the most important and controversial problems in contemporary philosophy. It is also essential to understanding many developments in logic, philosophy of language, epistemology and metaphysics. In this outstanding introduction to analyticity Cory Juhl and Eric Loomis cover the following key topics: The origins of analyticity in the philosophy of Hume and Kant Carnap's arguments concerning analyticity in the early twentieth century Quine's famous objections to analyticity in his classic 'Two Dogmas of (...) Empiricism' essay The relationship between analyticity and central issues in metaphysics, such as ontology The relationship between analyticity and epistemology Analyticity in the context of the current debates in philosophy, including mathematics and ontology Throughout the book the authors show how many philosophical controversies hinge on the problem of analyticity. Additional features include chapter summaries, annotated further reading and a glossary of technical terms making the book ideal to those coming to the problem for the first time. (shrink)

This review considers ethical challenges to research design and informed consent in biomedical and behavioral studies conducted in resource-poor settings. A review of the literature explores relevant social, cultural, and ethical issues in the conduct of biomedical and social health research in developing countries. Ten case vignettes illustrate ethical challenges that arise in international research with culturally diverse populations. Recommendations for researchers and policy-makers concerned about ethical practices in multinational studies conducted in resource-poor settings are also listed.

Alexander George has put forward a novel interpretation of the Quine-Carnap debate over analyticity. George argues that Carnap's claim that there exists an analytic-synthetic distinction was held by Carnap to be empty of empirical consequences. As a result, Carnap understood his position to be empirically indistinguishable from Quine's. Although George defends his interpretation only briefly, I show that it withstands further examination and ought to be accepted. The consequences of accepting it undermine a common understanding of Quine's criticism of Carnap, (...) and I argue that it is difficult to find a perspective from which Quine can criticize Carnap in a non-question-begging way.

In this book about the philosophy of education, Loomis and Rodriguez carefully examine the first principles of theoretic and practical reason necessary for human development and flourishing. Collaborating with the genius of C.S. Lewis, and particularly his brilliant work The Abolition of Man , the authors offer a multi-facetted, interdisciplinary investigation of perennial questions that impact human development and freedom. What is the human being? What are essential criteria for human flourishing? What is the best institutional framework for education? (...) What are the non-naturalistic, normative constraints to the ordering and functioning of a social institution like education? Are there particular institutional environments that threaten moral agency and human freedom? Are there information patterns and practices that substitute one institutional vision of reality for another? Is there a model of education that reflects truer structures of reality? Is there a particular vision embodied in the logic of institutional growth? (shrink)

This article critically examines Saul Kripke's (1972) argument for the separability of necessary truths from truths known a priori, focusing on his criticism of the standard meter case presented by Wittgenstein (1968). It attempts to show that Kripke's argument is unworkable on any of several readings. Wittgenstein's own broadly conventionalist account of necessary truth is then considered in the light of the standard meter example.

Uncertainties about how to achieve sustainable and reliable biobased value chains can be remedied by inclusion of local biomass producers. Such inclusion implies that the knowledge, values, interests and skills of these local producers are integrated into the set-up, design, development and associated distribution of risk and benefits of the specific value chain. To make sure that this inclusion is both fair and effective, capabilities of relevant actors need to be taken into account, i.e. the capabilities of biomass producers and (...) of companies and local governments. Building on these capabilities can lead to context sensitive design of biorefineries that allow for true inclusion of local stakeholders. We support this claim with reference to the case of sugarcane production in Jamaica. (shrink)

Ignorance is essential to life as we know it. Foreknowledge of the future would preclude choice, responsibility, individuality—even history. True knowledge of the past would obviate historiography. Without human ignorance of God's larger plan, His omnipotence and benevolence would not make sense, given the evils of the world. Full knowledge is the enemy of both intimate and impersonal relationships; for that matter, even less important personal decisions are made in ignorance. Military strategy and natural science both depend on ignorance, as (...) do the law and politics—especially inasmuch as the latter requires myths that divide the world into good and evil forces.

Forgiveness is much more than isolated acts and words of individuals. The capacity to discover what it means to forgive and be forgiven depends, in part, on the richness of one's communal practices and disciplines.
