In regard to Heidegger, I confess that I find him difficult to read. I gleaned a few things from my attempts:
- Human hands evolved as instruments for grasping the world. Grasping is a huge step toward making use of the world. Our eyes and brains help focus this innate predisposition toward taking parts of the world and making them do things.
- Because our ability to manipulate the world is individually advantageous and to the species, and because we’ve evolved cultural mechanisms for transporting across time and space useful knowledge about how to manipulate the world, humans tend to see the world as a “standing reserve” of resources for our use.
