The death of Rabbi David Hartman in Israel on Sunday has deprived the Jewish world of one of its most forward-looking thinkers.

The Shalom Hartman Institute he founded endeavoured to find bridges between rabbinic tradition and the pluralism of contemporary Jewish life.

Rabbi Hartman was one of the speakers at Traditional Alternatives, the symposium of Orthodox thought in London staged in 1989 shortly before Jonathan Sacks was appointed Chief Rabbi.

But, sadly, I am not sure he would have been included in such an event were it to have been held 20 years on.
