In the centuries following Maimonides, Arabic-speaking Jews continued to engage with philosophy and mysticism, and wrote many fascinating original works. These works, authored over 300 years, were almost entirely lost. They are now being rediscovered, published, and studied, for the first time in centuries. We will discover a number of thinkers from the lost period, and read some fascinating texts that are both deeply Jewish, and deeply informed by Islamic philosophy and Sufism.
