nationalism

 

One of the great contradictions of human psychology is our notorious double-standard with respect to how we treat others, as a rule.  If a person is viewed as being one of “us” – a member of our group, or our religious faith, or our nation – we are predisposed to cooperate with them, to empathize with their hardships, come to their assistance if needed, and sometimes even sacrifice our lives for them.  Because they are members of our “tribe”, we view them as sharing a common fate.
