The Rashba and Rambam
The Rashba defended Rambam (Maimonides) during contemporary debates over his works, and he authorized the translation of Rambam's commentary on the Mishnah from Arabic to Hebrew.
Nevertheless, the Rashba was opposed to the philosophic-rationalistic approach to Judaism often associated with Rambam, and he was part of the beit din (rabbinical court) in Barcelona that forbade men younger than 25 from studying secular philosophy or the natural sciences (although an exception was made for those who studied medicine). On July 26, 1305, the Rashba wrote:
"In that city are those who write iniquity about the Torah and if there would be a heretic writing books, they should be burnt as if they were the book of sorcerers."
