Caveat discipulus…

As we lick our pencils, we might send thoughtful birthday greetings to Immanuel Kant; he was born on this date in 1724. One of the central figures of modern philosophy, Kant is remembered primarily for his efforts to unite reason with experience (e.g., Critique of Pure Reason [Kritik der reinen Vernunft], 1781), and for his work on ethics (e.g., Metaphysics of Morals [Die Metaphysik der Sitten], 1797) and aesthetics (e.g., Critique of Judgment [Kritik der Urteilskraft], 1790). But he made important contributions to mathematics as well: Kant’s argument that mathematical truths are a form of synthetic a priori knowledge was cited by Einstein as an important early influence on his work.
There is … only a single categorical imperative and it is this: Act only on that maxim through which you can at the same time will that it should become a universal law.
– Chapter 11, Metaphysics of Morals
