The key idea behind reduction is a simple and familiar one: it’s that there’s more to things than meets the eye. Surprisingly, this simple idea provides the resources to block a number of notable anti-reductionist arguments: Mackie’s argument from queerness against objective moral values, Kripke’s Humphrey objection and its recent variants, and Jubien’s objection from irrelevance against Lewisian modal realism. What is wrong with each of these arguments is that they suppose that what is to be reduced must not be dissimilar to what it is to be reduced to. This supposition is shown to be misguided and that the success or otherwise of a reduction turns on quite different considerations.
Ever since the rise of the so-called analytic school in 20th century philosophy, philosophical analysis has often been considered to be synonymous with conceptual analysis. However, criticism has also been levelled at the conceptual analysis procedures, which undermined confidence in the merits of conceptual analysis. As far as the clarification of concepts is concerned, explication is therefore sometimes proposed as an alternative means. Combining historical and systematic perspectives, this volume collects new work on analytical and explicatory methods within 20th century philosophy. The contributions explore how clarificatory and reformatory methods of engaging with concepts have been construed and utilized by such different authors as Aristotle, Russell, Wittgenstein, Carnap or Mackie, marking out underappreciated congruencies and reevaluating historical disputes. They explore the role of analysis in metaphysics as well as metaethics and examine how methodological accounts relate to underlying ideas about concepts.
