In this paper I argue that Beall and Restall's claim that there is one true logic of metaphysical modality is incompatible with the formulation of logical pluralism that they give. I investigate various ways of reconciling their pluralism with this claim, but conclude that none of the options can be made to work.

Logical pluralism is the view that there is more than one correct logic. In this article, I explore what logical pluralism is, and what it entails, by: (i) distinguishing clearly between relativism about a particular domain and pluralism about that domain; (ii) distinguishing between a number of forms logical pluralism might take; (iii) attempting to distinguish between those versions of pluralism that are clearly true and those that are might be controversial; and (iv) surveying three prominent attempts to argue for logical pluralism and evaluating them along the criteria provided by (ii) and (iii).

In this paper I explore the extent to which a perspectival understanding of scientific knowledge supports forms of “scientific pluralism.” I will not initially attempt to formulate a general characterization of either perspectivism or scientific pluralism. I assume only that both are opposed to two extreme views. The one extreme is a (monistic) metaphysical realism according to which there is in principle one true and complete theory of everything. The other extreme is a constructivist relativism according to which scientific claims about any reality beyond that of ordinary experience are merely social conventions.

Pluralism: The Philosophy and Politics of Diversity is the first volume to open the window on philosophical pluralism and link pluralist themes in philosophy and politics. It advances recent debates on political pluralism in a range of essays that challenge or defend the association of liberalism and pluralism. The volume is divided into three parts: an investigation of the philosophical sources of pluralism, including an essay on William James; the value of pluralism and liberalism, discussing the compatibility of these ideas; and an investigation of difference in pluralism, with writing on women, ethnocultural, and the public-private distinction.

In this book, Robert Talisse critically examines the moral and political implications of pluralism, the view that our best moral thinking is indeterminate and that moral conflict is an inescapable feature of the human condition. Through a careful engagement with the work of William James, Isaiah Berlin, John Rawls, and their contemporary followers, Talisse distinguishes two broad types of moral pluralism: metaphysical and epistemic. After arguing that metaphysical pluralism does not offer a compelling account of value and thus cannot ground a viable conception of liberal politics, Talisse proposes and defends a distinctive variety of epistemic pluralism. According to this view, certain value conflicts are at present undecidable rather than intrinsic. Consequently, epistemic pluralism countenances the possibility that further argumentation, enhanced reflection, or the acquisition of more information could yield rational resolutions to the kinds of value conflicts that metaphysical pluralists deem irresolvable as such. Talisse’s epistemic pluralism hence prescribes a politics in which deep value conflicts are to be addressed by ongoing argumentation and free engagement among citizens; the epistemic pluralist thus sees liberal democracy is the proper political response to ongoing moral disagreement. While developing his view, Talisse engages central issues in contemporary liberal political theory, including toleration, state neutrality, public justification, and the accommodation of illiberal sub-cultures. This book will be of interest to ethicists, political philosophers, and political scientists.

This review essay is an in-depth evaluation of Michael P. Lynch's book Truth in Context. Lynch argues that metaphysical pluralism-- the idea that truth propositions and facts concerning the nature of reality are relative to conceptual schemes or worldviews-- is compatible with realism about truth. It is argued that Lynch is correct that there are consistent, interesting, and nontrivial forms of pluralism. However, much needs to be done to think that pluralism is the correct theory of truth.

I criticize conceptual pluralism, as endorsed recently by John Dupre and Philip Kitcher, for failing to supply strategies for demarcating science from non-science. Using creation-science as a test case, I argue that pluralism blocks arguments that keep creation-science in check and that metaphysical pluralism offers it positive, metaphysical support. Logical empiricism, however, still provides useful resources to reconfigure and manage the problem of creation-science in those practical and political contexts where pluralism will fail.

Beall and Restall [2000], [2001] and [2006] advocate a comprehensive pluralist approach to logic, which they call Logical Pluralism, according to which there is not one true logic but many equally acceptable logical systems. They maintain that Logical Pluralism is compatible with monism about metaphysical modality, according to which there is just one correct logic of metaphysical modality. Wyatt [2004] contends that Logical Pluralism is incompatible with monism about metaphysical modality. We first suggest that if Wyatt were right, Logical Pluralism would be strongly implausible because it would get upside down a dependence relation that holds between metaphysics and logic of modality. We then argue that Logical Pluralism is prima facie compatible with monism about metaphysical modality.
