George Carlin – Extreme Human Behaviour

“You know what’s interesting about assassination? Well, not only does it change those popularity polls in a big fucking hurry, but it’s also interesting to notice who it is we assassinate. Ya ever notice who it is, got to think who it is we kill? It’s always people who’ve told us to live together in harmony and try to love one another. Jesus, Gandhi, Lincoln, John Kennedy, Bobby Kennedy, Martin Luther King, Medgar Evers, Malcolm X, John Lennon – they all said, “Try to live together peacefully.” Bam! Right in the fucking head! Apparently, we’re not ready for that. Yeah, that’s difficult behavior for us. We’re too busy thinking around, sitting around trying to think up ways to kill each other.”

Michio Kaku – Will Mankind Destroy Itself?

“It’s humbling to realize that the developmental gulf between a minuscule ant colony and our modern human civilization is only a tiny fraction of the distance between a Type 0 and a Type III civilization – a factor of 100 billion billion, in fact. Yet we have such a highly regarded view of ourselves, we believe a Type III civilization would find us irresistible and would rush to make contact with us. The truth is, however, they may be as interested in communicating with humans as we are keen to communicate with ants.”
