"My tribe is always right. Other tribes are evil and the source of all my tribe's suffering."
"We've met the enemy, and he is us." Pogo, I think, had it right. And, "There is nothing to fear but fear itself" also seems relevant.
I think until we can each look in the mirror and deal with the enemy we see, we'll keep projecting our shadows onto some "other." Othering is psychological scapegoating. It's what created the Salem witch trials and the madness of McCarthyism. We seem to be approaching similar madness.
Large, ostensibly "American" corporations are draining the life out of this country far faster than any illegal workers. Speeders are our greatest daily threat to life and limb, not terrorists. Both the leaders of these corporations and the speeders I refer to are part of "us," this current tribe, but it's apparently more psychologically appealing (and I suppose less threatening) to view the enemy outside than the enemy among us, within us.
Burn the witches. Round up the Jews. Blacklist the sympathizers. Lock up the Japanese.
Maybe we aren't really evolving. But I still think we can.
I'll leave off with a few quotes from one of my favorite human beings who I never was fortunate enough (or old enough) to meet:
"We can't solve problems by using the same kind of thinking we used when we created them." - "Peace cannot be kept by force. It can only be achieved by understanding." - "Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe." - "The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed."
