Summary

German-Jewish Enlightenment philosopher who argued for religious toleration and the separation of church and state from within the Jewish tradition, and defended rationalist metaphysics including the immortality of the soul.

Core Contribution

Jerusalem: the state should not coerce religious belief; Judaism as a religion of revealed law (not dogma) is uniquely compatible with Enlightenment toleration — its laws regulate action but not belief. Phädon: rationalist argument for the immortality of the soul in Platonic dialogue form.

Key Spikes & Highlights

Was challenged by Johann Caspar Lavater to either refute Christianity publicly or convert — chose a carefully diplomatic response that demonstrated both philosophical integrity and political pragmatism.
Kant called him 'the greatest example' of a philosopher who could purify and uplift metaphysics, and the Pantheism controversy (Jacobi vs. Mendelssohn about Lessing's Spinozism) dominated the final years of his life.
