Abstract
Based on an assessment of the history and status quo of the concept of rationality within AI, I propose to establish research on (artificial) rationality as a research program in its own right, aiming at developing appropriate notions and theories of rationality suitable for the special needs and purposes of AI. I identify already existing initial attempts at and possible foundations of such an endeavor, give an account of motivations, expected consequences and rewards, and outline how such a program could be linked to efforts in other disciplines
