His principal work, published in French in 1994 and translated into English, is entitled Collective Intelligence: Mankind's Emerging World in Cyberspace.

[8] He was a member of the editorial board of the Revue virtuelle project of the Pompidou Centre in Paris from 1995 to 1997 and was the author of a report on cyberculture for the Council of Europe in 1996.

He claims that interactivity is a vague term that "has more to do with finding the solution to a problem, the need to develop new ways to observe, design, and evaluate methods of communication, than it does with identifying a simple, unique characteristic that can be assigned to a given system".

[citation needed] In Becoming Virtual: Reality in the Digital Age Lévy explores the way we virtualise every aspect of our lives, from real time (media) interaction through language, to our actions through technology, and our social relations through institutions.

[citation needed] Lévy's current project focuses on the development of an Information Economy MetaLanguage (IEML)[10] for the purposes of improving knowledge management as part of his works on the design of a universal system for semantic addressing of digital documents.
