Sam Harris, in his recent article called The Fireplace Delusion, tries to make you feel what it's like to react to a cached belief being irreparably destroyed. Just incase you forgot what your apostasy (if you had one, of course) was like in its early stages.
What are some of the Fireplace Delusions you've come across in your days?
EDIT: WOODSMOKE HEALTH EFFECTS
Wow that's new to me. The only real doubts I felt were that 1. considering the nature of the article this may be a trick that will be revealed at the end and 2. if this is true then how is burning wood fires possibly still legal?
I wish I wasn't primed beforehand with meta-stuff so I could know whether I would have accepted it under normal circumstances but I really can't imagine why I wouldn't.
Although, I remember questioning this in the past. It seemed unusual that only tobacco smoke would be especially unhealthy (even when smoked naturally); I had guessed that this probably implies the unhealthiness of other types of smoke but never bothered to research it.
For the same reason alcohol is legal: we've been using it so long it's unthinkable to ban it.
