Question

Hello Rabbi, I started reading your Quartet after finishing Truth but Not Certain.
I noticed a certain difference in how things are presented: in Truth but Not Certain you talk about how it is possible to reach truth but not certainty, and you are basically arguing against the assumption that truth = certainty. But in Two Carts you treat them as one package, or at least that’s how it seems from what I’ve read so far. Did something change between the books?
This question also touches on a somewhat broader one, in light of the publication of the new trilogy: is the Quartet still “relevant”? Do you still agree with what you wrote there, or did you write the trilogy in order to present a new doctrine? By the way, I still haven’t read the trilogy, but I wanted to ask anyway so I’d know.
Thank you very much, and happy holiday.
