Sometimes when you're thinking about a subject that you might want to write about -- or even form an opinion about -- you don't know quite where to start or how to proceed.
In rhetorical theory, this stage in the process of developing an argument -- coming up with ideas, thinking of something to say -- is called invention (inventio).
In the fourth century before Christ, the Greek philosopher Aristotle provided would-be orators with a wealth of topoi (sing. topos), literally places, intellectual places to explore, in his Rhetoric.
In their classic textbook, Writing, Gregory and Elizabeth Cowan (1980) adapted Aristotle's concept for modern use in the form of a heuristic, a sort of thought-provoking questionnaire that helps writers develop a more thorough understanding of a topic as they work through each stage. It has become one of my favorite teaching tools.
As superficially "obvious" as these questions seem, as you work through them there comes a point when you say, "Now that's something worth saying" or "I bet no one has looked at it this way before." Originality doesn't come from nowhere. It comes from asking "obvious" questions and thinking hard about the answers. NO CLICHES. Cliches kill brain cells. You're better off hitting yourself in the head with a brick.

I would not be the least bit surprised if anything Hubbard came up with was, well, borrowed without attribution. My guess would be that he borrowed topoi from Aristotle rather than from Cowan & Cowan, or do you think Cowan & Cowan borrowed their modernization from him? I'd have to see the Scientology questions to decide if they sound like copies or originals.
