"I am, therefore there is a God"
About this Quote
A neat inversion of Descartes, delivered with the calm audacity of an Enlightenment insider who still insists religion can survive the age of reason. Where "I think, therefore I am" tries to rebuild certainty from the inside out, Mendelssohn flips the hinge: existence itself becomes a breadcrumb trail back to God. The move is strategic. It turns the modern subject, newly empowered by rational inquiry, into evidence for the very metaphysical order skepticism wants to dissolve.
The specific intent is apologetic, but not in a pulpit-thumping way. Mendelssohn is arguing that faith need not be an embarrassment before philosophy. His claim doesn’t ask you to accept revelation first; it asks you to take seriously the fact of being and the conditions that make it intelligible. Subtext: the era’s fashionable atheism is less a triumph of logic than a refusal to follow logic to its uncomfortable end. If you grant that existence is not self-explaining, he suggests, you’ve already opened the door to something like God.
Context sharpens the stakes. Mendelssohn, a central figure in the Jewish Enlightenment (Haskalah), lived inside a Europe debating whether Jews could be citizens and whether religion could be rational. A proof-of-God line from him is also a bid for cultural translation: a way to defend Judaism without retreating into sectarian authority. It’s philosophy as social strategy - insisting that modernity doesn’t have to mean spiritual amnesia, and that the right kind of reason can serve as a bridge rather than a wrecking ball.
