Ursula K. Le Guin said this quote

Suffering is the condition on which we live. And when it comes you know it. You know it as the truth. Of course it's right to cure diseases, to prevent hunger and injustice, as the social organism does. But no society can change the nature of its existence. We can't prevent suffering. This pain and that pain, yes, but not Pain. A society can only relieve social suffering - unnecessary suffering. The rest remains. The root, the reality.
