The shared world : perceptual common knowledge, demonstrative communication, and social space

Description

"The Shared World offers a new treatment of the capacity to perceive, act on, and know about the world together with others. It develops the view that creatures capable of joint attention stand in a unique perceptual and epistemic relation to their surroundings: they operate in an environment that they, through communication with their fellow perceivers, help constitute. This environment is characterized by a specific spatial order. Joint perceivers determine the location of the object of their attention and action relative to their respective standpoints, and thus operate with a spatial frame of reference in which these standpoints are presented as centres of perception and action. The resulting theory casts light on a range of philosophical and psychological issues: the essay discusses demonstrative reference in communication, common knowledge about jointly perceived objects, and spatial awareness in joint perception and -action. It integrates these social phenomena into a more general discussion about the nature of mind and argues for their crucial relevance in the context of that discussion"--  Read more...
