Abstract
This essai discusses real-time/real-space research in which the time-space of the researcher and the time-space of the researched overlap, and in which action and reflection are intimately connected through fusion or cooperation. The paper first presents the principles of a pragmatic epistemology, and then briefly reviews real-time/real-space research strategies, particularly co-authorship, by reflective practitioners and pragmatic researchers who get involved together in theory building.
