Revelation @Hospital • I am caring for you because I feel like doing so. • I am caring for you although I didn’t feel like doing. • I acted out of my duty to care for you. More praiseworthy?
2Kantian ideas • How should I live? • Moral worth of actions • What are my duties? • Categorical imperative
2 Formulas “… common human reason, with this compass in hand, knows very well how to distinguish in every case what is good and what is evil, what conforms with duty or is contrary to duty.”
Imperatives • Hypothetical Imperative • Do this if you want that… • Depends on what you want • Categorical Imperative • Do this. • Independent of what you want
The Categorical Imperative 1 “Act only on that maxim whereby you can at the same time will that it should be a universal law.” Equality of persons: No arbitrary privileges
The Universalisability Test “It is wrong to act on any principle of which it is true that, if everyone accepted and acted upon this principle, or everyone believed that it was permissible to act upon it, that would make it impossible for anyone successfully to act upon it.”
Can it be universalised? • State the principle of action • Consider what would happen if everyone follows that principle • If it results in the impossibility of following that principle, then the action is not universalisable. Test of unfair privilege
Keeping promises • I wish to borrow $1000 from you. • You ask that I promise to return it. • I consider promising while intending to break the promise
Universalisable? Principle: Promise but intend to break it If everyone promises but intends to break her promise. No one will believe promises anymore Cannot be universalised
Application: False Promises Kant: “the universality of a law that everyone . . . could promise whatever he pleases with the intention of not keeping it would make the promise . . . impossible, since no one would believe what was promised him but would laugh at all such expressions as vain pretenses.”
Crafty liar Principle: Making false promises only when not under suspicion What if everyone makes false promises only when not under suspicion? People will continue to believe promises Can be universalised?
Humanity Kant: “I say that man, and in general every rational being, exists as an end in himself, not merely as a means for arbitrary use by this or that will.”

Against human dignity “To allow one’s person for [the sake of] profit to be used by another for the satisfaction of sexual desire, to make of oneself an object of demand, is to…make of oneself a thing on which another satisfies his appetite, just as he satisfies his hunger upon a steak.” Immanuel Kant
