title: The prospects of primitivism

authors: Wyatt, Jeremy

abstract: Primitivist theories of truth date back at least to the origins of analytic philosophy, being defended by Moore, Russell, and Frege. A number of contemporary philosophers have also defended primitivist truth theories, with Davidson’s and Sosa’s defenses probably being the best known. The most extensive development of primitivism, however, has been offered by Jamin Asay, who contends that the concept TRUTH is primitive while the property truth is non-primitive yet insubstantial. In this talk, my primary aim will be to critically assess Asay’s primitivism. I’ll explain why his signature argument for primitivism is inconclusive and why his views face a pair of formidable challenges. After defending these negative claims, I’ll suggest that the way forward for inquiry about TRUTH is to move away from purely a priori investigations and towards a sort of inquiry which recognizes the critical role of empirical questions about the nature and acquisition of TRUTH.

title: Anisotropic viscous dissipation in three-dimensional magnetic merging solutions

authors: Litvinenko, Yuri E.

subjects: magnetohydrodynamics (MHD) – sun

abstract: Aims: We consider viscous and resistive energy dissipation in the flaring solar corona. Methods: We compute energy dissipation rates, associated with magnetic merging in three dimensions. We examine an exact 3D solution for steady magnetic merging in a viscous resistive incompressible plasma. We use the Braginskii stress tensor to model viscous effects and derive scalings for the resistive and viscous dissipation rates. We evaluate the dissipation rates for typical parameters of solar active regions. Results: Large-scale advective flows required to sustain resistive current sheets are shown to be associated with significant viscous losses.
