The truth about what the COS
claims for Hubbard's academic credentials happens to be exactly the same as every single other
claim the COS has ever made and continues to make about anything.
They
claim whatever them can get away with at the moment.
For example, the early books' claim that the author was a "doctor and nuclear physicist", after thoroughly being debunked, were erased like a engram in later editions. Hubbard and his well-funded propaganda apparatus then expended substantial resources and marketing efforts in the ensuing decades to assert a litany of not as easily debunked proclamations and jingles about Hubbard's mastery of so many disciplines & arts. Some examples are:
"Mankind's Greatest Friend"
"Source"
"Commodore"
Ron the Musician
Ron the Humanitarian
Ron the Photographer
Ron the Writer
Ron the Movie Maker
Ron the Explorer
Ron the Botanist
Ron the Bigamist
Oh, wait, I don't think the COS published that last one. They much prefer to show winning photos of Dr. Hubbard.
Especially photos of Ron the Happy Husband" wearing navy costumes and waving to his adoring fans with one hand--while the other affectionately holds Mary Sue Hubbard's hand just before he framed her for Operation Show White felonies that sent her away to federal prison. That reminds me. . .
Ron the Buddha, Mettreya and Betraya'
