Against Magnitude Realism

In recent work, Christopher Peacocke has argued for a kind of realism (or anti-reductionism) about magnitudes such as temperature and spatial distance. Peacocke’s argument is that are an ineliminable commitment scientific everyday explanations (including high-level explanations), they the natural candidates semantic values our ordinary magnitude talk, contents mental states. I critique these arguments, in particular focusing on whether realist satisfactory account how facts grounded lower-level facts. argue less (i.e., more reductionist approach) preferable, or at least viable. also aim to substantially clarify what stake debate.
