We will have to let go of our hope for a controllable world and accept our own comparative powerlessness. --I think this would be a good thing to do in lots of spheres. It's not the same as being fatalistic or abrogating responsibility, because you stay involved and still try to work on the things you can work on, but you recognize that the world isn't 100 percent controllable.

You know the saying "an ounce of prevention is worth a pound of cure"? But actually, you want some cure too, for when prevention doesn't work. Similarly, since we can't control everything, we have to have *some* capacity to deal with adverse, unexpected events.
