Carl Jung coined the notion of the Collective Unconscious. The theory is that when shielded by the anonymity of a crowd, people will abandon their personal values to surrender to the contagious emotions of the crowd. A crowd thus assumes a life of its own, stirring up emotions and driving people toward irrational action. Freud called it Crowd Psychology.  

Liberalism depends on the Collective Unconscious to move ahead it's global warming agenda. How's that? Leftwing political activists know that it does not matter if it's hot or cold outside. What matters is that if enough Americans  BELIEVE it's hot, then indeed it will be hot. And the more Americans that believe it's getting hotter, the hotter it will get. Then eventually it will get so hot, America will ask the Government to step in and make it colder - even if that means a loss of our Constitutional rights. They need the Collective Unconsious because nobody can proove Global Warming, nor can we even FEEL it.

I experienced this phenomenon myself yesterday. I was in Denver stuck at the airport. A late winter storm had stopped air traffic. It was snowing, and it was cold. But a young teenage girl sitting next to me was explaining to her friends how she was "so" worried about global warming. Pretty soon her friends were all in agreement and they belabored it together. Now I realize that one day's bad weather does not make a climate, but it cannot be argued that hell froze over this winter. This is, in fact, the coldest winter on record in the United States. Did you get that? Coldest ON RECORD. So this teenage girl didn't believe in global warming because she was hot (she was wearing a winter coat and scarf), but because someone told her it was getting hot. And now her friends believe it too.

The Collective Unconscious is a dangerous thing. McCarthy needed it. King Ferdinand needed it. Hitler needed it. Al Gore needs it too. I cannot recall anything in my lifetime, or in American history, that got so much attention despite so little evidence or even personal experience (none of us feel like things are really getting hotter).
