In Plato’s Republic, Socrates argues that justice is good not only for its consequences but also in and of itself. Challenged by Glaucon and Adeimantus, who suggest that all human interactions are inherently competitive and that being unjust could help you get the better in these conflicts, Socrates establishes that justice is good because it is harmony in the city and in the soul. If justice is a kind of health of the soul, then surely it is better to be just than unjust. This claim might ameliorate the concerns of Glaucon and Adeimantus, but I will argue that Plato does more than address the vision of justice brought forth by Socrates’ interlocutors. Particularly through the contrasts among the different kinds of lives that are either described or depicted in the Republic, Plato points his readers toward a conception of justice that reveals it as the ground of mutuality, reciprocity, dialogue and friendship. In fact, the Republic reveals justice to be necessary to the philosophical life and, hence, to the best kind of life.

Well-known ties between arithmetical proof and intuitionistic logic make it natural to think of provability in terms of intuitionistic logic and hence absolute provability in terms of one of its extensions. For this reason, we propose Intuitionistic Tense Logic, or tINT, to study absolute provability. We delineate tINT models and a Hilbert-style system, and then prove soundness and completeness. We then use the tINT framework to discuss and compare ideas of absolute provability of authors in the literature.

The Saul Kripke Center is pleased to announce that Vincent A. Peluce (PhD student, Philosophy, CUNY Graduate Center) will deliver the fourth Saul Kripke Center Young Scholars Series talk on Thursday, December 5, 2019, from 2:00 to 4:00 in room 9206 of the CUNY Graduate Center.

This event will feature a thought-provoking panel discussion with sexual and reproductive justice experts on the value of the sexual and reproductive justice framework and how it can be applied to diverse stakeholders, settings, and contexts. Panelists will also highlight examples from around the world of momentum towards sexual and reproductive justice.

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.
