  Baudrillard continues this line of thought in his 1999 text Impossible Exchange (2001). In three parts containing a series of short essays, he first develops his concept of an “impossible exchange” between concepts and the world, theory and reality, and subject and object. He attacks philosophical attempts to capture reality, arguing for an incommensurability between concepts and their objects, systems of thought and the world. For Baudrillard, the latter always elude capture by the former, thus philosophy is an “impossible exchange” in which it is impossible to grasp the truth of the world, to attain certainty, to establish a foundation for philosophy, and/or produce a defensible philosophical system.
