|Western science rests on procedures reductive of diversity in particular
because it takes into account only linear causality. This reduction is all the more
fundamental since its aim is generalisation and mathematisation. The consequence for
social sciences and humanities are the loss or the reduction of spatio-temporal
references, the elimination of reference to the subject and historical and evolutionary
characteristic of scientific knowledge. Today the planetarisation of exchanges forces
social sciences and humanities specialists to reconsider their processing and management
of human diversity.
