The book significantly influenced modern culture in a variety of ways.
Church of All Worlds
A central element of the second half of the novel is the religious movement founded by Smith, the "Church of All Worlds", an initiatory mystery religion blending elements of paganism and revivalism, with psychic training and instruction in the Martian language. In 1968, Oberon Zell-Ravenheart (then Tim Zell) founded the Church of All Worlds, a Neopagan religious organization modeled in many ways after the fictional organization in the novel.[17] The spiritual path included several ideas from the book, including polyamory, non-mainstream family structures, social libertarianism, water-sharing rituals, an acceptance of all religious paths by a single tradition, and the use of several terms such as "grok", "Thou art God", and "Never Thirst".
Heinlein objected to Zell's lumping him with other writers such as Ayn Rand and Robert Rimmer; Heinlein felt that those writers used their art for propaganda purposes, while he simply asked questions of the reader, expecting each reader to answer for him- or herself. He wrote to Zell in a letter: "... each reader gets something different out of the book because he himself supplies the answers. If I managed to shake him loose from some prejudice, preconception or unexamined assumption, that was all I intended to do."[18]
Though Heinlein was neither a member nor a promoter of the Church, it was formed including frequent correspondence between Zell and Heinlein, and Heinlein was a paid subscriber to the Church's magazine Green Egg. This Church still exists as a 501(c)(3) recognized religious organization incorporated in California, with membership worldwide, and it remains an active part of the neopagan community.[19]
Grok
The word "grok", coined in the novel, made its way into the English language. In Heinlein's invented Martian language, "grok" literally means "to drink" and figuratively means "to comprehend", "to love", and "to be one with". The word rapidly became common parlance among science fiction fans, hippies, and later computer programmers[20] and hackers,[21] and has since entered the Oxford English Dictionary.[22]
Fair Witness
The profession of Fair Witness, invented for the novel, has been cited in such varied contexts as environmentalism,[23] psychology,[24] technology,[25] digital signatures,[26] and science,[27] as well as in books on leadership[28] and Sufism.[29] A Fair Witness is an individual trained to observe events and report exactly what is seen and heard, making no extrapolations or assumptions. While wearing the Fair Witness uniform of a white robe, they are presumed to be observing and opining in their professional capacity.[30] Works that refer to the Fair Witness emphasize the profession's impartiality, integrity, objectivity, and reliability.[31][32]
An example from the book illustrates the role of Fair Witness when Anne is asked what color a house is. She answers, "It's white on this side." The character Jubal then explains, "You see? It doesn't occur to Anne to infer that the other side is white, too. All the King's horses couldn't force her to commit herself... unless she went there and looked – and even then she wouldn't assume that it stayed white after she left."[30]
Waterbed
Stranger in a Strange Land contains an early description of the waterbed, an invention that made its real-world debut in 1968. Charles Hall, who submitted a waterbed design to the United States patent office, was initially refused a patent on the grounds that Heinlein's descriptions in Stranger in a Strange Land and another novel, Double Star (1956), constituted prior art.[33]
