What does it mean when he says don't use any physical examples just expand on the main concept. Also how is Greed related to "war as a social disease" and how is empathy related. We need to explain the main concept with no examples. I'm struggling and I really do appreciate your help.

Answer 1

Greed is a cause of war. It's contagious as each nation strives to get more than its neighbors. Fear may be a cause of greed is a nation is afraid that it will lose status and power if it doesn't acquire more land and resources.

When a culture or person is sick with a disease, it saps its strength so that there's no room for empathy.
