There are no textbooks for Jedi, no colleges, no dojos. To learn about the Force and become a Jedi, a character must be trained, by one who already understands.
Why? Why are there no textbooks for Jedi?
There's this newfangled invention, you see, which -- if you can imagine such a thing -- is somehow able to convey information and understanding from one person to another, even when one of them
is not even present!
It's called a book!
Why, exactly, is it impossible to learn how to be a Jedi from a book? How hard would it be to write down stuff like "the Force is a thing", "focus", and "you have to believe really hard"? The book could be
one page! If you really wanted to work it and turn it into a series to keep the publishing company happy, you could call the first book BELIEVE and the next one FOCUS! ( Or BELIEVE 2: JEDI BOOGALOO, whatever. )
A wacky conspiracy theorist might suggest that the real reason a Jedi must be trained by a living, breathing master is to artificially limit the number of Jedi out there. Because if
everyone can use the Force, Philistine, all you'd have to do is mass produce a "Force for Dummies" book and if the thing really caught on you'd have billions of Jedi popping up everywhere!
And how the hell does this writer get away with claiming there's no such thing as a Jedi textbook or a Jedi college? It's as if he never even watched the prequels or the sequels and just stopped at the OT! Like, try to grasp that what you saw in the OT was a few survivors of a pogrom,
in extremis, and not at all what things would be like under normal circumstances...
