Some issues just won't go away. One of these is whether Rav Soloveitchik זצ"ל was in favor of co-education, ab initio, or only ex post facto. A friend recently sent me this discussion of the issue by R. Shmuel Eliyahu, the Chief Rabbi of Safed (and a leader of the Hardali communuty).
Essentially he makes two points. First, the Rav nowhere wrote that co-education was permissible, halakhically. Second, unnamed students of the Rav were interviewed by Shaul Schiff of the late, lamented HaZofeh. His findings were, not surprisingly for a Hareidi publicist, that co-education at Maimonides was a concession to the times.
With all due respect, R. Eliyahu is wrong. First, his argument from the lack written sources discussing the issue is, at best, disingenuous. Anyone who knows anything about Rav Soloveitchik knows that he hardly ever wrote (never mind published) his halakhic decisions. This might be regrettable. It is, however, a fact. Similarly, the Rav never wrote a programmatic essay on the positive need for a broad secular education. Yet can anyone, save the most extreme revisionists, deny that (as Professor Twersky זצ"ל once wrote) that such a need was self-evident?
As far as Shaul Schiff's article (which is no longer on line), since I don't know who he asked, there's no way of knowing how reliable his sources were. I can only repeat what I know from close family members (as reported by Seth Farber here). The Rav and Rebbetzin never considered co-education an halakhic issue. For them it was an educational question. They were convinced that separate classes would deprive the girls of the same level of Torah and academic excellence as the boys. Therefore, co-educational classes, ipse facto, were self-justifying.
Since Rav Shmuel Eliyahu and his followers oppose equal education for girls, obviously such considerations are of no import.
[As for his claim that co-education is in violation of the Shulchan Arukh, hasn't he ever heard of the Levush?]
