Just one line from 'The Mysterious Mr.Quin', Agatha Christie

This line from 'The Mysterious Mr. Quin' (by Agatha Christie) has really struck me:

" 'Has it ever struck you,' he said, 'that civilization's damned dangerous?' "

Overwhelming. Don't you think??

Side Note: I'm happy because it's a long time since I published a post in english for the last time. I missed it. I know it's a short one, but I think it gets the point.
