We examine the modes of intervention of global public intellectuals at times of crisis. In critical situations, public intellectuals take positions on matters that affect the societies they inhabit and, eventually, all humanity. To this end, they take advantage of the opportunities afforded by new communications technologies, establishing an important distinction between the “analog” intellectual (who relies on the slow time of books, opinion columns, and bookstores) and the “digital” intellectual who uses modern information and communications technologies. To study the activities of global public intellectuals and their political influence, we propose to leave aside the notion of “transnational intellectual field” in favor of an understanding of a transnational intellectual stage peopled by a certain type of intellectual agent whose symbolic and cultural production is disseminated through a digital global public circuit. To illustrate the functioning of a circuit of this type, we take the example of the Project Syndicate platform.
