If the Mediterranean people in the days of the Roman Empire had known about dynamite they would never have been conquered by iron. If the Native Americans had learned to smelt metals in greater numbers they would have had a defence against muskets. Throughout history the description of every nation is a description of what the people did not know.
We teach it as a progression of what they knew. It looks better that way. It seems we are going upwards, we are learning more. And yet history teaches us clearly we are living in and through, our ignorance.
And this isn’t just about war. Had we known about the dangers in monoculture in crops the Irish Famine may never have happened, if we had had an early understanding about forests for clean air and water tables, many floods could have been avoided. Ignorance costs lives.
Look around your world. People are dying and suffering because we are ignorant. We have not learned enough about learning.
