Too often today it seems we find ourselves communicating from radically different perspectives on the world and we often despair of communication even being possible. Peter Ludlow argues that perspectival content, or what some call indexical content, is ineliminable and ubiquitous, running through our accounts of human action and emotions, perception, normative behaviour, and even our theories of computation and information. While such content may be ineliminable, it also gives rise to philosophical puzzles - particularly those involving reporting these contents from different perspectival positions. Such puzzles have led some to try and abandon perspectival content, and others to despair of communication across diverse perspectival positions. Ludlow argues that communication across diverse perspectival positions is not only possible, but routine, and develops a theory of interperspectival content and cognitive dynamics to explain how it is accomplished.
