In a discussion with my father yesterday he outlined the primary reason for war. He stated that warfare occurs when humans identify with a smaller group of humans and no longer see humanity as a whole. He also reported that there are three ways in which people identify with a smaller group; these are ethnicity, race, and religion. When we are unable to recognize that we are all made from the same flesh, blood and spirit and humanity is one we begin to kill each other.
