I have recently finished reading the Manga of Nausicaa of the Valley of the Wind and can't recommend it highly enough. However some aspects of it I'm struggling to understand. It is a post-apocalyptic story. The earth became hostile to humanity due to a disaster many hundreds or thousands of years ago. Humans are clearly in decline and extinction is a real and imminent possibility.
Late in the story we learn that steps were taken to preserve the best elements of human civilization. Technology, art and music have been stored away for preservation. It's even revealed that
The giant insects and toxic jungle were constructed for the express purpose of purifying the earth of toxins, so that human civilization can be rebuilt. And it's explicitly intended that the rebuilt civilization will be peaceful.
Yet Nausicaa finds something about this enterprise to be grossly offensive. She says:
I suppose those men left that black thing to be the kernel of the reconstruction... and it never occurred to them that that itself was the ultimate demonstration of contempt for life.
She has reason to be angry, given that some of the preserved technology has been shared and used for nefarious purposes with catastrophic results. A considerable portion of the remaining land capable of supporting human life has been lost and many people have died as a result. Yet from the quote above, and from her arguments with the Master of the Crypt it's clear that she disagrees in principle with what has been done. It's not simply that some powerful technology was misused by bad people. She doesn't think that the project of restoring the world and rebuilding civilization should have been done in the first place.
Why does she believe this shows "contempt for life"?
