Kant · Reading guide for episode 3 · Samuel Woodall and Jack Thomson

The third Kant conversation turns from the limits of knowledge to practical reason: what makes an action moral, and how can duty express freedom rather than merely restrict it? Use this guide to read the Groundwork alongside the published conversation.

The reading route

Begin with the good will and Kant’s distinction between acting in accordance with duty and acting from duty. Then examine false promising, the universal-law test, respect for humanity and the kingdom of ends. Compare freedom understood as following a desire with autonomy understood as rational self-legislation.

Read before listening

Read the Groundwork free in Abbott’s translation. Focus on sections I and II; identify a maxim before asking whether it could become universal law.
