I used Harris's app, and was a bit surprised to hear him use language that he'd savage anyone else for.

I get the problem there; you're trying to teach what something feels like, and there just aren't words.

It's not surprising that you can alter the brain by various exercises, or that those exercises are counterintuitive. The brain is complicated and our tools for manipulating it are baroque. Still, it was a little weird to hear Harris give in without apparently reconsidering other forms of mental exercise from that standpoint.
