Charles Hartshorne:

“Are we making progress?” should not reduce entirely to “Are we coming to own more things?” It should include “Are we learning to do without some material things?” … The clearest basis for respect for nature is to renounce two forms of dualism: an absolute difference between matter and mind, and a quasi-absolute difference between the human and other forms of mind.
