Native-born writers who published their work in the 1940s and 1950s, often called the "War of Independence generation," brought a "sabra" mentality and culture to their writing. S. Yizhar, Moshe Shamir, Hanoch Bartov and Benjamin Tammuz vacillated between individualism and commitment to society and state. In the early 1960s, A.B. Yehoshua, Amos Oz, and Yaakov Shabtai broke away from ideologies to focus on the world of the individual, experimenting with narrative forms and writing styles such as psychological realism, allegory, and symbolism.
