Un savoir à contre-courant: l'interdisciplinarité en action dans les sciences humaines et sociales = Knowledge against the grain: interdisciplinarity in action in action in the humanities and social sciences

Interdisciplinarity has emerged as a critical response to the rigid boundaries of disciplinary specialization, reflecting a need for cross-disciplinary thinking to address complex, shared issues. Since the 1970s, scholars like Bachelard, Popper, and Morin have argued for integrating diverse knowledge domains, countering the hyper-specialization that dominates the 20th and 21st centuries. This focus on isolated expertise often limits broader perspectives, leading to an "expert's right" that restricts access to complex issues requiring collaborative insight. Yves Couturier highlights two key aspects of interdisciplinarity: (i) its role as a critique against imperialistic knowledge representations and (ii) its practical basis in action, crucial for policies and services centered on individual well-being rather than isolated silos. Interdisciplinarity resembles interculturality, challenging researchers to reflect on their fields and approach other disciplinary perspectives with openness. This relational knowledge is essential for tackling hybrid issues—such as climate change, pandemics, and migration—that require integrated approaches. The article examines the nature of interdisciplinarity and proposes ways to enhance methodological pluralism, advocating for the inclusion of knowledge formed outside traditional Western frameworks.
