This essay develops a new interpretation of Moses Mendelssohn’s ontological argument in the Morning Hours: Lectures on God’s Existence. At the beginning, Immanuel Kant’s famous criticism of the ontological proof of God’s existence in the Critique of Pure Reason is presented. Then I offer an in-depth analysis of Mendelssohn’s original ontological argument in the Morning Hours. It is shown that with Mendelssohn’s new proof of God, Kant’s objections are answered. Finally, it is explained why Mendelssohn does not succeed in completely (...) refuting Kant’s objections. (shrink)
