Sefer HaIkkarim (Hebrew: סֵפֶר הָעִקָּרִים, romanized: sēp̄er hāʿiqqārim, lit. 'Book of Principles') is a fifteenth-century work by rabbi Joseph Albo, a student of Hasdai Crescas. It is an eclectic, popular work, whose central task is the exposition of the principles of Judaism.[1]
The work contains several internal contradictions. While most scholars see this as indicating Sefer HaIkkarim is an eclectic work, lacking originality and vision, recent scholars instead see this as one of Albo's methods for conveying esoteric messages.[2]
