Joseph Herman Hertz's theology placed him in the traditional group within the acknowledgement school although he was influenced by its scientific, romantic and aesthetic branches. This chapter examines Hertz's position on secular learning, non-Jews and non-Jewish religious movements, and on Jews and Jewish movements. It looks at how Zionism fitted into Hertz's theological outlook. The chapter establishes Hertz's religious attitudes, traces their origins, and identifies Hertz's religious and intellectual inspirations. It compares Hertz's views with those of Jewish religious leaders with different attitudes and also looks at how Hertz's approach can be seen as a reaction to those attitudes and as interventions in an ongoing debate within Judaism. The chapter argues that Hertz was a member of the group of traditionalists who wished to acknowledge what they considered to be the valuable aspects of modernity.
