It is indeed as though the interdisciplinarity which is today held up as a prime value in research cannot be accomplished by the simple confrontation of specialist branches of knowledge. Interdisciplinarity is not the calm of an easy security; it begins effectively (as opposed to the mere expression of a pious wish) when the solidarity of the old disciplines breaks down—perhaps even violently, via the jolts of fashion—in the interests of a new object and a new language neither of which has a place in the field of the sciences that were to be brought peacefully together, this unease in classification being precisely the point from which it is possible to diagnose a certain mutation.
