Two-level human

Prompted by the celebration of bin Laden's death, an article in the New York Times talks about the two qualities underlying the natural selection:

• Lower-level (selfish self): Humans are selfish and will compete aggressively with others in the group. This concept promotes the selfish nature of humans.
  
  
• Higher-level (collective self): Humans as collectives compete with other collectives for the survival of the group, not individuals. In other words, each one of us focuses on something that is bigger than each one of us.
  

The question is how can we apply this understanding to workplace or community that promotes the higher-level thinking rather than the lower-level thinking of selves.
