Jack Forbes 'Columbus and other cannibals' . It made me realize that what I used to call civilization was too often the opposite. I learned (remembered) that groups of people and philosophies exist outside of the Western(or 'modern') line of thought who are by default silenced or drowned against the mainstream, but who we should probably listen to - considering we are walking towards growing ecological disaster. Forbes' book and then 'Braiding Sweetgrass' (cause you can't always be angry) made the world make sense again.
