Eric Hoffer (1902-1983)
You dehumanize a man as much by returning him to nature - by making him one with rocks, vegetation, and animals - as by turning him into a machine.
Both the natural and the mechanical are the opposite of that which is uniquely human.
Nature is a self-made machine, more perfectly automated than any automated machine. To create something in the image of nature is to create a machine, and it was by learning the inner working of nature that man became a builder of machines.
It is also obvious that when man domesticated animals and plants he acquired self-made machines for the production of food, power, and beauty
