Ralph Metzner, psychologist, and author, teamed up with Richard Alpert and Timothy Leary during the early 60’s in studying psychedelics at the Harvard University. His 45-year long career was centered on consciousness research where he focused on shamanism, meditation, and, of course, psychedelics.
This 24-minute long video contains an interview of Metzner and where he explains that he is not promoting the use of psychedelics. Rather, he just wants everyone to know that it can help in re-establishing the connection between man and nature. This one reason why he co-founded the non-profit organization called Green Earth Foundation. It aims to “heal and harmonize” the relationship between man and the environment.
