Reading group: Kant’s Groundwork, Section I, the good will and the honest shopkeeper
Most readers skip straight to the formulas of the categorical imperative, and for years so did I. I want to read the beginning properly: Section I of the Groundwork of the Metaphysics of Morals (1785), where Kant starts from what he calls ordinary moral understanding.
It is about a dozen pages in the Akademie edition, 4:393 to 4:405, and dense, so I propose three weeks.
Week 1 (4:393–396). The famous opening claim that nothing can be thought good without limitation except a good will. Then the odd argument that nature would not have given us reason if our purpose were merely happiness, since instinct would serve that better.
Week 2 (4:397–401). The examples of acting in accordance with duty versus from duty: the shopkeeper who does not overcharge an inexperienced customer, the person who preserves his life, the sympathetic person who enjoys helping others. And the propositions about duty and respect for the law.
Week 3 (4:402–405). The first statement of the universal-law formula, the lying-promise example, and Kant's closing remarks on why ordinary people need philosophy at all.
Mary Gregor's translation in the Cambridge edition gives the Akademie numbers in the margin. Any translation that does so is fine. I would especially welcome readers who come to Kant from outside the European tradition, because Section I makes claims about what “everyone” already knows that seem worth testing.
