“Barbarism is the natural state of mankind. Civilization is unnatural. It is a whim of circumstance. And barbarism must always ultimately triumph.” ~ Robert E. Howard in his story Beyond the Black River.
This is a good insight by Robert E. Howard. In the short term, a civilization dominated by intellectuals might score some victories, but barbarism always triumphs in the end. By barbarism, I mean the political and cultural forces that are ruthless, realistic, religious, passionate, energetic, ambitious, tradition-bound, and innovative. Barbarism does not entail mindless destruction.
From history we learn that the greatest acts of mindless destruction have been caused by the civilizations which were dominated by the intellectuals (the most recent examples are communism, nazism, fascism, and neoliberalism). Mindless intellectualism is the death sentence for a civilization.
