" There was something lacking – in him, he thought, not in the place. He was not up to it. He was not strong enough to take what was so generously offered. He felt himself dry and arid, like a desert plant, in this beautiful oasis. Life on Anarres had sealed him, closed off his soul; the waters of life welled all around him, and yet he could not drink. "

― Ursula K. Le Guin , The Dispossessed (Hainish Cycle, #6)
