While reading the wiki bio of R' Shimshon of Sens, a few statement there caught my eye.
The Rash sided with the opponents of the Rambam in their disputes.
condemned Rambams' rationalistic views on bodily resurrection and Talmudic haggadah
reproached Rambam for not having indicated the Talmudic sources in his Mishna Torah
he did express his great admiration for the Rambam saying, "I have heard that the gates of wisdom have been revealed to him"
The source for all these is given as the Artscroll book 'The Rishonim', page 136-137. True, it is all there. But I want to know Artscroll's source. Where are these words of R' Shimshon found?
Part 2. While looking in the Artscroll section mentioned I saw another curious statement which I would like to source.
Rambam's son, R' Avraham , heard that R' Shimshon disagreed with his father (presumably on matters basic to Judaism, e.g., G-d's incorporeality) but refused to credit the report.
Where is this statement of Avraham ben HaRambam to be found?
