"A Life (Un)Worthy of Living" is a comprehensive study that examines the different approaches of German and Israeli societies to the question of the value of life. Based on a variety of empirical materials, the research illustrates how social, cultural, religious, and legal frameworks in Germany restrict the selection of embryos through prenatal diagnoses, while in Israel there is a strong promotion of these practices. Through a detailed comparative analysis, the study highlights the tension between the quality and sanctity of life, leading to a provocative discussion about reproductive genetics. The study employs contemporary social theories to capture the political dimensions of life and to understand the differences between these two societies, which diverge significantly in their attitudes toward reproductive genetics. This results in an original intercultural discussion about the current techno-medical manipulations of life.
