Very interesting article on The Conversation website under the heading "Hubris, power and the correct way to topple dictators: an interview with David Owen".
Quote from the article:
Owen has established the Daedalus Trust to raise awareness about the phenomenon of hubris. “It must not be seen as purely negative – it is essential to risk taking. But we must become aware of it as a problem in every domain of life … business for instance. It has taken post-traumatic stress disorder 20 years to become accepted as a real, genuine phenomenon which needs treatment and attention. It may take another 20 years for the hubris syndrome to be similarly recognised as an acquired personality change – and as a huge problem.”
