Rothblatt is one of the more consequential people to found a religion in the last fifty years, and the biography explains the doctrine better than the doctrine does. She founded the satellite radio venture that became Sirius, then founded United Therapeutics after her daughter was diagnosed with pulmonary arterial hypertension, developing treatments for a disease that had been considered a death sentence — a life spent, in other words, treating mortality as a problem that yields to sufficient effort. Terasem follows from that rather than departing from it. She is filed as a teacher rather than a messenger because Terasem claims no revelation: the Truths are presented as propositions she wrote and that participants are expected to interrogate, and the movement is explicit that they are questions.
