Crescas Hasdai ben Abraham (c. 1340 - 1410/1411) was a Jewish philosopher and a renowned halakhist. His halakhic works - if indeed he ever committed such work to writing - have not reached us. But his concise philosophical work The Light of the Lord was the ultimate Jewish refutation of medieval Aristotelianism, and a harbinger of the scientific revolution in the 16th century.


The Light of the Lord (Hebrew: Or Hashem or Or Adonai)
The Refutation of the Christian Principles (polemics and some philosophy)
Passover Sermon (religious philosophy and some halakha)
