Expressivism in logic is the view that logical vocabulary plays a primarily expressive role: that is, that logical vocabulary makes perspicuous in the object language structural features of inference and incompatibility (Brandom, 1994, 2008). I present a precise, technical criterion of expressivity for a logic (§2). I next present a logic that meets that criterion (§3). I further explore some interesting features of that logic: first, a representation theorem for capturing other logics (§3.1), and next some novel logical vocabulary for (...) expressing structural features of inference (§4).

Naturalism is perhaps the most pervasive “-ism” in contemporary philosophy. Different variations of naturalism can be found in virtually all corners of theoretical and practical philosophy. Critics have rightfully noted that it is (a) often not clear what “naturalism” means exactly and, subsequently, (b) whether those who consider themselves naturalists in the same philosophical debate actually hold compatible, let alone the same, beliefs. -/- Among the different forms of naturalism that hold currency today, scientific naturalism seems to be the most (...) widespread and therefore articulated. It can be summarized as the ontological thesis that what exists are solely the entities posited by the natural sciences and the methodological thesis that philosophical inquiry should take the results of the natural sciences as authoritative. The paradigm of scientific naturalism has received a growing amount of critical attention from within and outside of analytic philosophy in the last few decades. The main thrust of a host of these critiques is to “soften” the claim of scientific naturalism by rejecting its reductionist or even eliminativist implications, yet retaining a commitment to naturalism under a new description. This has led to a proliferation of new forms of naturalism that seek to broaden the criteria which determine what belongs to the natural world, usually self-titled as a “liberal” or “relaxed” naturalism. Within the analytic tradition, naturalism has been thus critiqued since the 1990s by thinkers like Hornsby, Strawson, Nagel, Stroud, Putnam, McDowell or more recently Baker, De Caro, Macarthur, Beale & Kidd, Cahill & Raleigh. Such critiques are commonly motivated by Neo-Aristotelian and/or Wittgensteinian intuitions. From outside the analytic tradition, phenomenologists in the Husserlian tradition as well as thinkers in the Idealist tradition have been steadfastly critical of scientific naturalism as well, albeit for different reasons. However, these new proposals all have to contend with scientific naturalism and its more restrictive criteria for what counts as natural (although these are debated in their own right). (shrink)
