LEAD: L. RON HUBBARD: Messiah or Madman? By Bent Corydon and L. Ron Hubbard Jr. (Lyle Stuart, $20.) The Church of Scientology is a bizarre cult, and its founder and leader, L. Ron Hubbard, was a "cosmic outlaw," in the words of L. Ron Hubbard Jr. There is little of the son in this book but a good deal of Bent Corydon, who headed one of the Scientology "missions" in California during the 1970's until Hubbard decided to take over these lucrative franchises, leaving their well-rewarded leaders bewildered and broke.
