If psychedelics are, on any level, to be taken seriously as catalyzers or expanders of consciousness, then we need them, because it's an absence of consciousness that is making this historical transition so excruciating.
This is ideological colonization. They colonize people with ideas that try to change mentalities or structures, but this is not new. This was done by the dictatorships of the last century.
Where psychedelics comes together with that is that it's going to require a transformation of human language and understanding to stop the momentum of the historical process, to halt nuclear proliferation, germ warfare, infantile 19th century politics, all these things. It cannot be accomplished through a frontal assault upon it by political means.
