Famous Stories
The Rashba stood at the head of the rabbis' controversy over the study of philosophy. Around 1305 he imposed, together with other rabbis of his time, a ban on the study of philosophy and the natural sciences before the age of 25, with the exception of the works of the Rambam. The ban was intended to preserve the faith of the young students from the influence of Aristotelian philosophy. The Rashba reinforced the ban twice more. His letters in this controversy were included in the work Minchat Kenaot by Rabbi Abba Mari of Lunel, who esteemed the Rambam's Guide for the Perplexed yet opposed the study of philosophy.
The Rashba was among the rabbis most esteemed by Rabbi Yosef Karo, the author of the Shulchan Aruch. In the introduction to his work Beit Yosef, Karo counted him among the pillars of halachic decision. Elsewhere Rabbi Yosef Karo wrote of him: 'A surging spring, the pillar of the world, by whose light light is seen.' This praise reflects the standing of the Rashba as one of the greatest decisors in all the generations.
The Rashba answered thousands of responsa to Jewish communities in all the diaspora — from Spain and Provence, from France and Ashkenaz, and as far as the Land of Israel and the East. His responsa deal with every field of halacha — forbidden and permitted, Sabbath, marriage, monetary law, and more. His responsa became renowned throughout the diaspora, and became a foundation of halachic decision for the generations. Thus the Rashba became the spiritual leader of the Jews of Spain and of all the diaspora in his generation.
