 Natural law. Albo was one of the first Jewish philosophers to specifically address the concept of natural law along with his contemporary Zerahia Halevi Saladin. Apparently, this was due to the influence of the Christian theologian Thomas Aquinas, who classified laws in his book Summa Theologica. Albo’s view of natural law has attracted the attention of many scholars, in comparison to other topics in his philosophy, but the popular view among these scholars is that Albo did not attach great importance to this concept (Guttmann 1955, 176–184; Lerner 1964; Novak 1983, 319–350; Melamed 1989; Ehrlich 2006; Ackerman 2013).
