The Sleeping Beauty problem is test stone for theories about selflocating belief, i.e. theories about how we should reason when data or theories contain indexical information. Opinion on this problem is split between two camps, those who defend the “1/2 view” and those who advocate the “1/3 view”. I argue that both these positions are mistaken. Instead, I propose a new “hybrid” model, which avo...

Abstract This article applies some conceptual tools from semiotics to better understand the disastrous impacts of world economy on global ecology. It traces accelerating production material disorder and waste logic money sign, as economic processes simultaneously increase exchange-values entropy.

Stewart Cohen’s (1984) New Evil Demon argument raises familiar and widely discussed concerns for reliabilist accounts of epistemic justification.

Juan Comesaña (2002; 2010) has recently and prominently claimed that his Indexical Re...

We have outfitted a mobile research robot with several sensors and algorithms designed to facilitate smalland large-scale navigation and natural language interaction. We begin with a parser using a large, hand-crafted English grammar and lexicon. We then add a standard gradient navigation algorithm for local obstacle avoidance, and a line segment comparison algorithm for basic, high-performance...
