Abstract

According to Marc Peschansky, one of the leaders in biotechnological research in France, «with stem-cells, the imagination is in charge». This paper explores the new role of imagination in the converging technologies (NBIC report) in their relationship to practice. For the great German philosopher Hans Jonas, it is knowledge (positive: what we know, or negative: what we don’t know) that must guide our action. With converging technologies (nano-, bio-, info- and cogno-), knowledge and technique are relegated to the rank of servants of imagination: it is the triumph of imagination. The paper examines ways to fight the dizziness we feel about this potential reign of unlimited possibilities, no longer limited by the principle of reality
