R. Chaim David Halevy, prominent and recently deceased halakhic authority, former Chief Sephardic Rabbi of Tel Aviv, is quoted as being of the following view in Rabbi Haim David Halevy: Gentle Scholar and Courageous Thinker:
Rabbi Halevy remarked that Rambam, who was himself a prominent doctor, relied on contemporary medical and scientific knowledge, even when that information was at time in conflict with opinions of rabbis in the Talmud.[31] Indeed, the rabbis in the Talmud themselves admitted that non-Jewish scholars sometimes had more accurate scientific knowledge.[32] This was a tribute to our rabbis' commitment to truth.Evidently, he disagreed with those who signed the ban against Rabbi Slifkin's books that this view is unacceptable and heretical.
