The danger [of this enterprise], in short, is that instead of providing a basis for what already exists …, one is forced to advance beyond familiar territory, far from the certainties to which one is accustomed, towards an as yet uncharted land and unforeseeable conclusion … Is there not a danger that everything that has so far protected the historian [consultant, manager, psychologist …] in his daily journey and accompanied him until nightfall … may disappear, leaving for analysis a blank, indifferent space, lacking in both interiority and promise? (Foucault 1972, p. 39)
