Tzvia Greenfield is the director of the Mifneh Institute, which teaches tolerance, liberalism and democracy. Greenfield was a member of the 17th Knesset on behalf of Meretz. She has a doctorate in political philosophy from the Hebrew University. Her thesis analyzes the phenomenology of traditional social and political systems versus the phenomenology of modern (and post-modern) democratic thought.
Beyond her interest in philosophical theorization, Dr. Greenfield is interested in actual political processes. As the director of Mifne' Institute for Democracy and Cultural Identity, an educational think tank concentrating on issues of Jewish identity and civic culture, Dr. Greenfield has developed research and communicational tools for the analysis of active processes in cultural and civic identification. Following more than 15 publications and text books dealing with questions of cultural identity as manifested through various disciplines, she has published in 2001 her first broad cultural and political analysis, dealing with the rise of the religious political right in Israel.
