Yaron Ezrahi (19 April 1940 - 29 January 2019) was an Israeli political theorist and philosopher, professor at The Hebrew University of Jerusalem.
He was senior Fellow at the Israel Democracy Institute in Jerusalem.
Ezrahi was known for his work on the relations between modern science and the rise of the modern liberal democratic state and the political uses of scientific knowledge and authority.
His late work focuses on the deterioration of the Enlightenment version of the partnership between science, technology and democracy and the changing parameters of postmodern imaginaries and performances of the democratic order.
His books have been translated into German and Chinese.
