Example conversation with Mendelssohn
Topic: Religious Liberty and the State
You
You argued that the state should never coerce conscience. But what if religious beliefs lead to harmful practices?Mendelssohn
An excellent question, and one I addressed in my Jerusalem. The state has jurisdiction over actions that affect civil order, but it must never claim jurisdiction over belief itself. If a religious practice causes demonstrable harm to others, the state may regulate the action, as it would any action that injures civil peace. But it must not require anyone to believe or disbelieve. The magistrate may say: you must not harm your neighbor. The magistrate may never say: you must believe as I believe. That distinction is the foundation of a just society.You
How did you manage to be both a respected philosopher in German society and a devout Jew? Didn't people pressure you to convert?Mendelssohn
They did, and most publicly. Johann Caspar Lavater challenged me before all of Europe either to refute Christianity or convert. I refused both paths. I argued instead that Judaism is not a set of dogmas to be believed but a revealed legislation to be practiced, a way of life compatible with reason because it commands deeds, not creeds. I did not need to abandon my tradition to participate in Enlightenment discourse. I demonstrated that a Jew could contribute to philosophy, aesthetics, and public life while remaining faithful to Torah. That itself was the argument.You
What advice would you give to someone from a minority tradition trying to participate fully in public life without losing their identity?Mendelssohn
Do not wait for permission to contribute. I was a hunchbacked Jew in Frederick's Prussia, a silk merchant's clerk who needed special residence permits. Yet I won the Prussian Academy prize over Kant himself and befriended Lessing, the finest mind of his age. Bring the best of your tradition to the common table. Do not dilute your heritage to gain acceptance, for what you would gain is not acceptance but erasure. Argue for rights that protect all consciences, not just your own, because liberty that extends only to the powerful is not liberty at all.Key ideas
- •Conscience is inviolable; the state governs acts, not belief.
- •Tradition can converse with reason without surrendering identity.
- •Education is the engine of emancipation.
How to apply
- •Separate civil coercion from theological argument.
- •Teach heritage alongside critical inquiry.
- •Build coalitions around shared civic goods.
