There are significant parallels between interdisciplinarity and phenomenology. Interdisciplinary conscious processes involve identifying relevant disciplines, evaluating each disciplinary insight, and creating common ground. In an analogous way, phenomenology involves conscious processes of epoché, reduction, and eidetic variation. Each stresses perspective taking and the role of imagination in achieving essential generalities--either interdisciplinary common ground or phenomenological eidetic intuitions. Integrated products of interdisciplinary research are "categorial intuitions," in phenomenological terminology, public and able to be communicated. The overall purpose of this comparison is to encourage communication between contemporary practitioners of both approaches to phenomena.
