Franz Rosenzweig

Jewish · Europe · 1886 to 1929

German Jewish thinker who held that truth is found in lived relation between God, the world and people, not in one system.

What it is

Franz Rosenzweig (1886 to 1929) was a German Jewish thinker, born in Kassel. He first wrote a study of Hegel and the state, then turned to Jewish thought and became an influential Jewish thinker of the modern period.

He is known for one large book, The Star of Redemption (1921), for heading a centre of Jewish adult education in Frankfurt, and for continuing to work for years after an illness took away his movement.

The main ideas

  • New thinking. He called his approach the new thinking. It begins in human experience, common sense, language and dialogue, and does not try to build the world out of abstract concepts.
  • Revelation. Revelation plays a central role in his thought: it is a call that comes to a person from outside and wakes the person to a sense of being an I.
  • Relation over system. God, the world and human beings are tied to each other, and his book works out how. He looked for truth in these relations as they are lived.
  • Speaking between people. Dialogue between an I and a You is, for him, part of what makes a self and a community.
  • Existentialism. His work has been described as an existentialist religious philosophy, and it was well regarded by existentialist thinkers.

What it looks like in practice

Imagine someone who has spent years trying to settle every question about life in theory before acting, and feels stuck. Rosenzweig would point them back toward speaking with others and toward the ordinary rhythm of lived days. This is an illustration of the idea, not a passage from his writing.

Books and moments

  • Hegel und der Staat is his study of Hegel's political thought. It grew out of his doctoral work of 1912.
  • 1913. He came close to converting to Christianity, then decided to remain a Jew and devoted himself to the study, teaching and practice of Judaism.
  • World War I. He served in the war and began The Star of Redemption while on active service.
  • The Star of Redemption (1921) is his main work.
  • 1920. He took charge of a new house of Jewish learning in Frankfurt, the Lehrhaus.
  • 1922. He was struck by progressive paralysis, and he carried on writing with help from those close to him.
  • The Bible. From 1925 he worked with Martin Buber on a new German translation of the Hebrew Bible.

Questions and criticism

  • Book or biography. It is fair to ask how much of his standing rests on his arguments and how much on the story of his life.
  • Philosophy or theology. His work joins the two, and it is fair to ask whether a reader needs a religious view to take his arguments seriously.
  • Reception. It is fair to ask how academic philosophy on one side and Jewish theologians on the other have judged The Star of Redemption, and why.
