Can you find a Yeshiva two hundred years ago?
The ramchal and others who talk about what to learn all mention tanach; those who followed the rambam about being meshalesh definitely did so, and those who didn’t probably didn’t have fornal time spent on nach. Not everything which doesn’t come up in a bar ilan search is false
I think it’s also a nice fairy tale to claim that there’s no mesorah and that until the chasam sofer everyone just thought and did whatever they pleased, had no rebbe, no shimush, and accepted any obscure sefer written by anyone who lived in the times of the rishonim. In this fairy tale, no one is an apikores, no one ever thought that hilchos deos was a halachik issue, and of course no one uses agadeta as a source for daas torah. Come to think of it, in the same fairy tale, there was a Jewish army defending its citizens, democracy and total tolerance for LGBT people. There was also no rashu that says that klal yisroel does nothing without its leaders, and all non-kashrus decisions were made by individuals without consulting the archaic and out of date daas torah. They also used to look at the characters of tanach as being no different than you and me, with no particularly special spiritual levels and attributes, and believed that parts of chumash were added later and compiled by some shadow beis din which has no record.
Did i miss anything?
