In the second book of the Foundation trilogy, Foundation and Empire, written in 1953, the Mule appears, an amazing and intriguing character. Reading this book give me the sensation that George Lucas based his ideas of the Jedi and Sith orders around the influence of the Asimov tale.
Is there any evidence that Foundation series - especially the Mule - influenced Star Wars ideas of Jedi and Sith, given the multitude of acknowledged and unacknowledged-but-obvious influences that Lucas had?
Here's a fragment of the mule description:
One of the greatest conquerors the galaxy has ever seen, he is a mentalic who has the ability to reach into the minds of others and "adjust" their emotions, individually or en masse, using this capability to conscript individuals to his cause. Not direct mind-control per se, it is a subtle influence of the subconscious; individuals under the Mule's influence behave otherwise normally - logic, memories, and personality intact."
Can explain for example, one the Jedi/Sith main talents... and so on.
