Season 14 · 13 Apr 2026Language and thought: The case of Lavoisier- 49:01"I must eat to live" is not a duty; the verb must takes on meaning only where the opposite is possible.
Worked through in 12 videos · 12 passages.
Dominique Pagani returns regularly, from 2015 to 2026, to the same distinction: "I must eat to live" misuses the verb "must" (devoir), because it expresses a physical necessity, an "I cannot not", which in fact belongs to the realm of power (pouvoir)12. Duty in the strong sense only makes sense where I could do the opposite. It therefore presupposes choice and a space of freedom3. He takes the example of the red light: I must respect it because I can break the law, and freedom is thus maintained4. Moral duty then implies choosing a value5. He also contrasts duty with blind obedience: to obey out of duty is to obey a law that I recognize as well-founded6. On the political level, he brings up the distinction between what is and what ought to be. Hegel mocks the "ought" and wants reason to understand what is7. Marx studies what is in order to be able to change it, against utopian socialism8.
