Stewart Brand talks about the LSD trip that inspired his Whole Earth Catalog

In this remarkable 7-minute video shot in 2016, Stewart Brand recalls his experiences as a Merry Prankster in the San Francisco 1960s, the back-to-the-land movement, hippies, and the low-dose acid trip he took that made him wonder how humanity would be affected if people saw a photo of the entire earth taken from space. This led to the creation of The Whole Earth Catalog in 1968.
