Julie Klein, 1996:

"Argument remains inescapable. When interdisciplinary work is conceived as part of the 'natural' generation and gravitation of fruitful inquiries that will be located in the disciplinary system, assumptions about criteria tend to be strongly disciplinary. [...] In critical interdisciplinarities, radical change is the goal. The 'rhetoric of interpenetration' that is characteristic of critical interdisciplinarities does not simply enrich existing fields. It constructs new criteria and replaces them. It alters not only the products of research but the very procedures."
