Ursula K. Le Guin said this quote
“ Her concern with landscapes and living creatures was passionate. This concern, feebly called, the love of nature seemed to Shevek to be something much broader than love. There are souls, he thought, whose umbilicus has never been cut. They never got weaned from the universe. They do not understand death as an enemy; they look forward to rotting and turning into humus. It was strange to see Takver take a leaf into her hand, or even a rock. She became an extension of it, it of her. ”
