The Personalized A-Theory of Time and Perspective Vincent Conitzer∗ Abstract A-theorists and B-theorists debate whether the “Now” is metaphysically distinguished from other time slices. Analogously, one may ask whether the “I” is metaphysically distin- guished from other perspectives. Few philosophers would answer the second question in the affirmative. An exception is Caspar Hare, who has devoted two papers and a book to arguing for such a positive answer. In this paper, I argue that those who answer the first question in the affirmative – A-theorists – should also answer the second question in the affirmative. This is because key arguments in favor of the A-theory are more effective as arguments in favor of the resulting combined position, and key arguments against the A-theory are ineffective against the combined position. Keywords: metaphysics, philosophy of time, philosophy of self. ∗Departments of Computer Science, Economics, and Philosophy, Duke University, Box 90129, Durham, NC 27708, USA; Email:
[email protected] 1 1 Introduction In a series of unconventional but lucid works, Caspar Hare has laid out and defended a theory of egocentric presentism (or, in his more recent work, perspectival realism), in which a distinguished individual’s experiences are present in a way that the experiences of others are not (Hare, 2007, 2009, 2010). Closely related ideas appear in the writings of others. One example is Valberg (2007)’s notion of the “personal horizon,” especially considering his discussion of “the truth in solipsism” and his insistence that “my” horizon is really “the” (preeminent) horizon. Merlo (2016)’s “subjectivist view of the mental” is arguably even more closely related; he argues that “one’s own mental states are metaphysically privileged vis-a-vis` the mental states of others” and discusses in detail the relationship of his view to Hare’s.
