Title: Left-wing is best wing? The meaning and justification of political orientation.
Abstract: Political philosophers rarely analyse the categories of “left” and “right” in their own right, yet these labels structure much of public political debate. This talk, framed as a response to Joshi’s 2020 paper, What Are the Chances You’re Right About Everything? An Epistemic Challenge for Modern Partisanship, considers three questions. First, is there a shared justificatory and motivational core that unifies otherwise disparate left-wing (and right-wing) positions? Second, if such a core exists, can one be justified in endorsing a political orientation as such, rather than only particular policies? Third, are there arguments that favour the left, considered as a family of positions, beyond case-by-case evaluations? I argue (1) that there is a common justificatory and motivational basis across standard left positions; (2) that this basis supplies moral reasons to align with the left and makes it more likely than not that left positions will be correct on a randomly selected political question; and (3) that engaging these orientation-level questions can reconnect political philosophy with the concerns of practical politics.
