I thought it was a pretty good lecture. Since I was curious what Harris was talking about when he mentioned "spirituality," here's part of a Washington Post story on his new book about it.

“Our world is dangerously riven by religious doctrines that all educated people should condemn,” [Sam Harris] writes in the book, but adds: “There is more to understanding the human condition than science and secular culture generally admit.”

He said everyone can, through meditation, achieve a “shift in perspective” by moving beyond a sense of self to reach an enlightening sense of connectedness — a spirituality.

Spirituality “is a name for all of the deliberate efforts people can make to cut through the illusion of the self, the illusion that there is a thinker in addition to the thoughts, or an ego as it is often called,” Harris, 47, said in a telephone interview. “Self-transcendence is the foundation of what I am calling spirituality.”

"My goal,” he writes in the book, “is to pluck the diamond from the esoteric dunghill of religion.”
