The importance of incorporating value pluralism into a theory of justice is recognized in many conceptualizations of justice. This pluralism is often seen as a reason to attend to a range of perspectives, perspectives which can function as a source of information in determining which principles should guide justice. However, philosophy’s ability to properly attend to different perspectives has received extensive attention in the criticisms of various non-ideal theorists, who argue that ideal-theoretical philosophy runs the risk of excluding important aspects of actual social problems. Taking these criticisms on board, this paper builds on non-ideal theory by arguing for a Wittgensteinian family resemblance approach to justice. I will explain how this linguistic practice-embedded understanding of justice can be a helpful tool for non-ideal theory, as it can give us insight into why, in various similar but different cases, the notion of justice is seen as applicable. In light of this approach, I will suggest a reorientation of the pluralist demand towards an empirical starting point.
The controversial issue of information transfer in quantum teleportation procedure is analyzed in the framework of the many-worlds interpretation of quantum mechanics. In contrast to the claims of Deutsch & Hayden 2000, it is argued that quantum information, considered as a measurable property for an observer in a particular world, is transferred in a nonlocal way in the teleportation process. This, however, does not lead to action at a distance on the level of the universe which includes all parallel worlds. Preprint: https://philsci-archive.pitt.edu/21447/
