Certainly neo-Platonism, Plotinus and Porphyry and that school are psychedelic philosophers. Their idea of an ascending hierarchy of more and more rarefied states is a sophisticated presentation of the shamanic cosmology, which is the cosmology that one experientially discovers when they involve themselves with psychedelics.

Impressionism is simply twenty minutes into LSD.

Certainly the central Platonic idea, which is the idea of the ideas, these archetypal forms which stand outside of time is one which is confirmed by the psychedelic experience.

Culture is a simplification and a lie. It's the currency by which fools navigate the world. Smart people get beyond it.

Notice that the whole story of Eden is the story of the struggle over a woman's relationship to a psychoactive plant.

Inwardness is the characteristic feature of the vegetable rather than the animal approach to existence. The animals move, migrate and swarm, while plants hold fast. Plants live in a dimension characterised by solid state, the fixed and the enduring.

This is the truth that the shamans have always known and practiced. Awareness of the green side of mind was called Veriditas by the twelfth century visionary Hildegard Von Bingen.

...the mind is more powerful than any imaginable particle accelerator, more sensitive than any radio receiver or the largest optical telescope, more complete in its grasp of information than any computer: the human body- its organs, its voice, its powers of locomotion, and its imagination- is a more-than-sufficient means for the exploration of any place, time or energy level in the universe.
