A recent online article by Giulo Prisco drew attention to the fact that Octavia Butler’s fictional religion Earthseed (a major focus in her novel Parable of the Talents) has apparently inspired the creation of a real-life religion based on it. This new religion, Terasem, is intended to recall “Earthseed” although the article reflects some confusion about what language is being drawn on to make the name. Presumably “Earthseed” itself is copyrighted, although sometimes people like the mystery that is created by using obscure and foreign-sounding terms.
See also Steve Wiggins’ blog post which starts with Terasem and moves from there to transhumanism. Steve’s post in turn led me to discover an earlier article by Jessica Roy about Terasem, in TIME magazine.
