Dawkins points to some of science's achievements and describes it as freeing "most of us" from superstition and dogma. Picking up from his superstition-reason distinction in The Root of All Evil? (while recycling some footage from it), he then says reason is facing an "epidemic of superstition" that "impoverishes our culture" and introduces gurus that persuade us "to run away from reality". He calls the present day "dangerous times".
