A Paradise Built in Hell, Rebecca Solnit

"Disasters are, most basically, terrible, tragic, grievous, and no matter what positive side effects and possibilities they produce, they are not to be desired. But by the same measure, those side effects should not be ignored because they arise amid devastation. The desires and possibilities awakened are so powerful they shine even from wreckage, carnage, and ashes. What happens here is relevant elsewhere. And the point is not to welcome disasters. They do not create these gifts, but they are one avenue through which the gifts arrive. Disasters provide an extraordinary window into social desire and possibility, and what manifests there matters elsewhere, in ordinary times and in other extraordinary times."
