  Yet, as Heidegger argues in Being and Time (1927), taking this modern subject/object dichotomy as our point of departure leads us to fundamentally mischaracterize the way we experience the everyday world in which we are usually unreflectively immersed, the world of our practical engagements. By failing to recognize and do justice to the integral entwinement of self and world that is basic to our experiential navigation of our lived environments, modern philosophy effectively splits the subject off from objects and from other subjects. In this way, modern philosophy lays the conceptual groundwork for subjectivism, the “worldview” in which an intrinsically-meaningless objective realm (“nature”) is separated epistemically from isolated, value-bestowing, self-certain subjects, and so needs to be mastered through the relentless epistemological, normative, and practical activities of these subjects. Heidegger suggests that this problem is not merely theoretical, because the subjectivism of the modern worldview functions historically like a self-fulfilling prophecy. Its progressive historical realization generates not only the political freedoms and scientific advances we cherish, but also unwanted downstream consequences such as our escalating environmental crisis and less predictable side-effects like the aestheticization of  art.[21]
