Although Dianetics and Scientology were founded by L. Ron Hubbard, and all the scriptures are solely comprised of his writings and recorded lectures, he nonetheless wrote:

“Acknowledgment is made to fifty thousand years of thinking men without whose speculations and observations the creation and construction of Dianetics would not have been possible. Credit in particular is due to: Anaxagoras, Thomas Paine, Aristotle, Thomas Jefferson, Socrates, René Descartes, Plato, James Clerk Maxwell, Euclid, Charcot, Lucretius, Herbert Spencer, Roger Bacon, William James, Francis Bacon, Sigmund Freud, Isaac Newton, van Leeuwenhoek, Cmdr Thompson (MC) USN, Voltaire, William A. White, Will Durant, Count Alfred Korzybski and my instructors in atomic and molecular phenomena, mathematics and the humanities at George Washington University and at Princeton.”
