Wikipedia is on its way to becoming something of an institution in today’s intellectual landscape. What role, one might ask, is scientific expertise going to play here? According to Philippe Lacour, this problem is not so much going to find a solution inside the encyclopaedia’s framework, as it is going to be resolved in an external operationalisation process, following the twofold principle of clinical as well as critical differentiation. Wikipedia’s development is based on the dissembling and reassembling of knowledge and digital data, foreshadowing, undoubtedly, what will be a new form of intellectual life.
