Rather than describing psychedelic experiences, it presents four future-oriented ideas 'coming over the psychedelic horizon', which illustrate the potential benefits of psychedelics for humanity:
* Stanislav Grof's view of our minds as a way to understand works of art (looking at Disney's Snow White).
* The evidence that psychedelic-occasioned mystical experiences can boost our immune systems.
* Psychedelics as a way of adding new cognitive programmes to our thinking skills.
* Applying the ideas from Part 3 to learning.
