 Sefer ha-‘Ikkarim is composed of a preface, which includes a highly detailed table of contents; an introduction; and four treatises divided into chapters. Although Albo completed writing the book around 1425, scholars have long agreed that before the book was published in its entirety, a preliminary version appeared, comprising the first of the four treatises (Back 1869, 8–10; Tänzer 1896, 19–22, 27; Schweid 1967, 25).
