The passion for destruction is also a creative passion.
The destructive character lives from the feeling, not that life is worth living, but that suicide is not worth the trouble.
We shall not have succeeded in demolishing everything unless we demolish the ruins as well. But the only way I can see of doing that is to use them to put up a lot of fine, well-designed buildings.
Destruction, hence, like creation, is one of Nature's mandates.
