UU minister Tim Jensen, The Eclectic Cleric, offered in the comments one of his sermons as a follow-up to the recent posts on Timothy Leary (and, happily, with a connection to the current posts on Ram Dass). Check out this interesting link to read more about Leary’s background and evolution: The Most Dangerous Man in America.
As he notes, Leary and his fellow researchers were carrying out these experiments on seminarians of Andover Newton Theological School, a long-standing bastion of UU ministerial development. In fact, some of the participants in the Good Friday Miracle experiment, which involved ingesting psychedelics in order to determine their relationship to religious experiences, went on to become Unitarian-Universalist ministers.
