Abstract: In this paper, I take issue with a core commitment of logical conventionalism: that we impose a logic on ourselves by adopting general linguistic conventions governing our use of logical terms, thereby determining the meanings of the logical constants and which of our inferences are valid. Drawing on Kripke’s ‘adoption problem’, I argue that general logical principles cannot be adopted, either explicitly or implicitly. I go on to argue that the meanings of our logical terms, and the validity of our inferences, cannot depend on our adoption of logico-linguistic conventions.

Abstract: Poincare is well known for his conventionalism and structuralism. However, the relationship between these two theses and their place in Poincare's epistemology of science remain puzzling. In this paper I show the scope of Poincare's conventionalism and its position in Poincare's hierarchical approach to scientific theories. I argue that for Poincare scientific knowledge is relational and made possible by synthetic a priori, empirical and conventional elements, which, however, are not chosen arbitrarily. By examining his geometric conventionalism, his hierarchical account of science and defence of continuity in theory change, I argue that Poincare defends a complex structuralist position based on synthetic a priori and conventional elements, the mind-dependence of which precludes epistemic access to mind-independent structures.
