How does the semantic guess make sense here?


I am not so sure how backward thinker is contrasting enlightened here. Especially, if we focus on the Far from as the logic word.
Could someone shed light on it please?
@gregmat @vince @Joan or anyone who can help please.

Use the main idea of the first clause, not just “enlightened”. And you’ve also got the final clause that supports what kind of thinker he was.
