Kant (2) The Categorical Imperative
Imperatives • An imperative represents an action as something good to do • Hypothetical: good if you take some end as good (good as a means) • Categorical: good in itself
Morality gives us categorical imperatives • If moral law contained only hypothetical imperatives, then our reason to comply would derive from some end we were trying to accomplish. • But then there would be no such thing as a good will • Hence morality must give us categorical imperatives
“The” Categorical Imperative • General principle of practical reason underlying all categorical imperatives • General idea: act only on principles acceptable to all rational beings • Formulation: “Act only on that maxim whereby you can at the same time will that it should become a universal law”
The “CI Procedure” • Step 1: Propose a maxim • Step 2: Generalize it • Step 3: Transform it into a law of nature • Step4: Figure out the Perturbed Social World • Q1: Could I rationally act on my maxim in the PSW? • Q2: Could I rationally choose to live in the PSW?
Step 1: Propose a maxim • I am to do x in circumstances y in order to bring about z. • I am to lie on a loan application when I am in severe financial difficulty and there is no other way to obtain funds, in order to ease the strain on my finances. • Note: the proposal should be sincere • Note: the maxim should be instrumentally rational
Step 2: Generalize the maxim • Everyone is to do x in circumstances y in order to bring about z. • Everyone is to lie on a loan application when he is in severe financial difficulty and there is no other way to obtain funds, in order to ease the strain on his finances
Step 3: Transform it into a law of nature • Everyone always does x in circumstances y in order to bring about z • Everyone always lies on a loan application when he is in severe financial difficulty and there is no other way to obtain funds, in order to ease the strain on his finances.
Step 4: Figure out the Perturbed Social World • What would the world be like with the new law of nature? • Note: assume that in the PSW the new law is common knowledge • What would the world be like if it were common knowledge that everyone always lied on a loan application when ...
Q1: Could I rationally act on my maxim in the PSW? • “Rationally” means instrumental rationality • In the PSW, would doing x in circumstances y still be an effective means of achieving z? • In the PSW, would lying on a loan application when I am in severe financial difficulty and there is no other way to obtain funds still be an effective means of easing the strain on my finances?
Q2: Could I rationally choose to live in the PSW? • Don’t ask this question if you get a no answer to Q1 • Q1: “contradiction in conception” test • Q2: “contradiction in the will” test
Maxim of indifference to the needs of others • In order to advance my own interests, I will not do anything to help others in need unless I have something to gain from doing so. • X = refraining from helping someone in need • y = I don’t have anything to gain from helping • z = advancement of my own interests
Contradiction in conception? • In the PSW, would refraining from helping when I have nothing to gain still be an effective way of promoting my own interests? • Answer seems yes
Contradiction in the will? • Could I rationally choose the PSW as a world to live in? • Kant says no: I would be choosing not to be helped when in need unless it was in someone’s interest to do so, and this is not rational.
