Our experiences of the world can no longer be called direct, or primary. They are secondary, mediated experiences. Concrete covers whatever would grow from the ground.
Buildings block the natural vistas.
We are so surrounded by a reconstructed world that it is difficult to grasp how astonishingly different it is from the world of only one hundred years ago, and that it bears virtually no resemblance to the world in which human beings lived for four million years before that. That that would affect the way we think is rarely considered. We are left with no frame of reference untouched by human interpretation. When people cannot distinguish with certainty the natural from the interpreted, or the artificial from the organic, then all theories of the ideal organization of life become equal. None of them can be understood as any more or any less connected to planetary truth.
