Humans, by their very nature, tend to fall - and rather quickly - into thinking that their side has all the right answers. There was an old Star Trek episode where Captain Kirk was split into two separate beings by a malfunctioning transporter. One Kirk was brutal, aggressive and completely bereft of conscience, the other was empathetic, compassionate and introspective. The short story is that neither one could survive without the existence of the other.
As I always suspected, the answer to all the world's problems is William Shatner...
