The knowledge of the theory of logic has no tendency whatever to make men good reasoners.

Creator of Scientology.                          

L. Ron Hubbard founded the Church of Scientology in Camden, New Jersey in 1953.

L. Ron Hubbard moved to England where he supervised the growing organization from Saint Hill Manor near the Sussex town of East Grinstead, a Georgian manor house once owned by the Maharajah of Jaipur which Hubbard purchased in 1959. This became the world headquarters of Scientology.

Hubbard claimed that Dianetics could cure physical illnesses and increase intelligence. In his introduction to Dianetics, Hubbard called his discoveries "a milestone for Man comparable to his discovery of fire and superior to his inventions of the wheel and the arch".

Church members were expected to pay fixed donation rates for courses, auditing, books and E-meters, all of which proved very lucrative for the Church, which paid emoluments directly to Hubbard and his family.

"Fair Game" was introduced by Hubbard as a policy against people or groups that "actively seeks to suppress or damage Scientology or a Scientologist by Suppressive Acts." He defined it as: ENEMY — SP Order. Fair game. May be deprived of property or injured by any means by any Scientologist without any discipline of the Scientologist. May be tricked, sued or lied to or destroyed.

The Times, a daily national newspaper published in the United Kingdom, claimed in 2009 that British diplomats exposed Hubbard as "a fraud" in the 1970s.
