Meaning of the word 'Scientology'

Although today associated almost exclusively with Hubbard's work, the word "scientology" predates Hubbard's creation by several decades. Philologist Allen Upward used the word "scientology" in his 1901 book The New Word as a synonym for "pseudoscience",[47] and this is sometimes cited as the first coining of the word.[48] In 1934, the Argentine-German writer Anastasius Nordenholz published a book using the word positively: Scientologie, Wissenschaft von der Beschaffenheit und der Tauglichkeit des Wissens ("Scientology, Science of the Constitution and Usefulness of Knowledge").[49] Nordenholz's book is a study of consciousness, and its usage of the word is not greatly different from Hubbard's definition, "knowing how to know".[50] However, it is not clear to what extent Hubbard was aware of these earlier uses. The word itself is a pairing of the Latin word scientia ("knowledge", "skill"), which comes from the verb scire ("to know"), and the Greek λογος lógos ("reason" or "inward thought" or "logic" or "an account of").
