||The infosphere refers to an environment populated by informational entities, called inforgs (or informational organisms). The infosphere extends beyond the cyberspace, as it is to be intended as including both offline and analogue information. The philosophical reflection on the infosphere includes all the ontological, epistemic and ethical problems connected to the relation of organisms within such environment: the ontological nature of informational objects, their inner (moral) value and the interface between those objects. Other philosophical issues related to the Infosphere are the nature of informational media and their properties, e.g the trustability of informational sources and privacy. Such analyses rely on the underlying notion of information that is assumed as the substrate of the Infosphere and which can vary (from Shannon to quantum information). The thesis that the Infosphere coincides with the totality of what there is leads directly to an informational ontology. Outside of the philosophical debate, the term infosphere is used to refer to sets of informational infrastructure put in place and used to offer service; IBM uses explicitly the term to refer to its service infrastructure.
