  • Book: The Semantic Sphere: Computation, Cognition and Information Economy. Pierre Levy. Wiley-ISTE. 2011



"New advances in digital media offer unprecedented memory capacities, an omnipresent channel of communication, and ever-growing computational power. We must ask ourselves how we can exploit this medium in order to augment our own social cognitive processes for human development.

Through a combination of a profound knowledge of humanities and social sciences, and an understanding of computer sciences, Pierre Lévy proposes a collaborative construction of a global hyper-cortex, coordinated by a computable metalanguage.

By fully recognizing the symbolic and social nature of human cognition, we could transform our current, opaque, global brain into a reflexive collective intelligence."
