Early life Slater was born on May 15, 1927, in
Riverton, New Jersey, to Pauline Holman and John Elliot Slater, a shipping company president and chairman of the
New Haven Railroad. He also took up playwriting and helped found the Santa Cruz County Actors' Theatre, later becoming its artistic director. In the 1970s, Slater began to experiment with psychedelics again, after staying away from them for the most part since the early to mid-1950s, although he had smoked cannabis in the late 1960s. His interest in the
counterculture of the 1960s and the
human potential movement began to move towards the then emerging genre of
New Age literature with his book
The Wayward Gate: Science and the Supernatural (1977). It received many good reviews in the popular press, but more serious critical reviews panned it, with writer and book critic Gerald Jonas calling it
antiscience.
Film Slater collaborated with filmmaker Gene Searchinger on
Paradox on 72nd Street (1982), a one-hour TV documentary aired nationally by
PBS. The film features dialogue by Slater and
Lewis Thomas (known for his book
The Lives of a Cell, 1974) interspersed over film footage of a bustling city street filled with people. The "paradox" refers to a theme that Slater and Thomas both touch upon in their respective work, but is directly expressed by Thomas: "It is in our genes to live together and to depend on each other. To be our individual, separate selves and at the same time the working parts of others is a paradox. And to be human is to live in this paradox." Tom Jory of the
Associated Press and John J. O'Connor of
The New York Times both praised the film, with Jory describing it as "remarkable" and "worthwhile" while O'Connor called it "unusually stimulating" and "fascinating". Henry Allen of
The Washington Post disagreed, saying that the use of
crowd watching in film and television was cliché at that point.
Theatre work Several of Slater's plays were produced for the Santa Cruz Actors' Theatre in the 1990s. At least two featured women as lead characters.
To the Dump (1993) depicts a woman who compulsively
hoards trash, while
Bug (1994) tells the story about a woman who is the leader of a spiritual community that faces a turning point but finds help from a member of her family.
Bug was directed by Bonnie Ronzio and was considered bold and unconventional for its time; it was well-received.
April Showers (1999), Slater's ten-minute play about anthropomorphic
cutlery in a
dishwasher, was chosen as a winning entry for the Santa Cruz
Eight Tens @ Eight festival in 2000, and was given a five-week run. Slater performed in the same festival in the role of "James" in a production of
Love and Death by
Kathryn Chetkovich.
Later life and death Slater began teaching again in his eighties in the doctoral program in Transformative Studies at the
California Institute of Integral Studies. He died of
non-Hodgkin lymphoma in
Santa Cruz, California, at the age of 86 on June 20, 2013. According to his daughter
Dashka Slater, her father did not own a car and "his only possessions fit into two small storage bins, in his view, proof of a life well-lived". ==Interest in democracy==
