(1) Does "because it holds great promise" mean "because free will holds great promise"?
If so, why not used "because it held great promise" since the author first expressed "no one was moved (to enjoy the existence of free will)"? Used past tense, then use it along in the same sentence.
The author has some liberty about the verb tenses in order to communicate the desired nuance. There's also personal preference and regional variations to take into account. The author used the past tense in "was ever" to suggest that his claim is true no matter how far back into the past you go. S/he could have used "is ever," but the nuance would be limited to the present.
However, both in the past, present and future, it is true that free will doesn't hold great promise as an abstract idea, so the simple present is used.
Quote:(2) Does "this notion" still refer to "free will"?
Yes.
