"Torah min Hashamayim B'aspaklariya shel Hadorot" (תורה מן השמים באספקלריה של הדורות) was written by R' Abraham Joshua Heschel and published by Soncino Press and JTS Press in 1962. It was translated into English by R' Gordon Tucker in "Heavenly Torah as Refracted through the Generations" in 2006.
The book is based on the thesis that there were two main schools in the times of the Tanaim which differed on a wide range of fundamental issues, halachic and aggadic (although the book deals mainly with the aggadic topics). These were the school of R' Akiva and the school of R' Yishmael. R' Akiva was representative of a more mystical approach to things, while R' Yishmael typified a more rational approach. The book moves through the many topics on which they differed chapter by chapter and not a page goes by without several quotes or references to Talmudic or midrashic literature to support this thesis. (I am aware that Heschel was not the first to state this observation; however, he is possibly the first to elaborate on it at such great length and with so many sources, certainly with respect to the aggadic issues.)
I'm specifically looking for a review of this book by a more traditional figure within Orthodox Judaism. (I say this because although it is unclear to me just from online information the state of R' Heschel's religious affiliation, it is at least clear that he is not what we would call a "traditional" source.) [Also, I am familiar with R' Gil Student's review posted when the translation was published. I am looking for the review of a more prominent and authoritative figure, if it exists, and preferably more in-depth.] However, I would also be satisfied with a (in-depth) discussion of this topic (R' Akiva vs. R' Yishmael) offered by a more traditional source.
