Before Toren died, I didn't believe in the power of positive thinking. It wasn't anywhere on my radar. Since his death, I find it totally offensive. If our thoughts really could affect the physical world, he would be alive. All the parents who were excitedly waiting for their babies to be born would be taking care of them, raising them, holding them, instead of living with the grief and stigma associated with stillbirth.
I saw this video and I love the way it exposes the cruelty and destructiveness of the idea that "thinking positive" is some kind of sane and logical life strategy. The art is cool too. It's by the RSA, their website is here, and the speaker is Barbara Ehrenreich.
