Dr. Griffith's research seems perfectly acceptable to me. I do not quite understand Peterson's objections that this experiment made it through an ethics committee. The participants in this subject have every right to willingly partake, and the experiment should be legal on the grounds of personal liberty alone.

The mystical and psychedelic experience is certainly real, as he sums up in the end. It is part of the human capacity and likely is for many life forms on this planet and others - to some degree or another.
