1. History of PhilosophyLecture 17Immanuel Kant’ Ethics By David Kelsey

2. Immanuel Kant • Immanuel Kant: • 1724-1804 • was born in Konigsberg in what was then Germany. • lived in Konigsberg his entire life and he was never married. • Interestingly, didn’t publish his first work, The Critique of Pure Reason, until 1781, when he was 57. • Widely regarded as one of the most influential and important philosopher’s of all time.

3. Deontological Theories compared toConsequentialist theories Immanuel Kant’s moral theory is a Deontological theory not a Consequentialist one. Consequentialist moral theories: Put the good before the right They first specify what good is of value. What is right is just whatever maximizes what’s good. So it is the consequences or end results that matter… Deontological moral theories: Put the right before the good. Do not: first specify some good and then determine what is right by asking what will maximize that good. Instead, Deontological theories determine what is right through some other method: and direct you to do what is right even if some other act would produce greater happiness. But Deontological theories don’t think consequences don’t matter. They think consequences are not the only thing that matters…

4. Deontologists Deontologists like rules. A rule tells us whether an action is right or wrong just on the basis of what kind of action it is, rather than on the basis of its consequences. For example, ‘Never kill the innocent’. Is it general enough? Or the Golden Rule: ‘Act the way you would like everyone to act’. Is it clear enough?

5. Kant’s picture • Personhood: Kant’s moral theory stems from his view of personhood. • For Kant, a person is just an agent. • An agent is rational: • To be rational is to be capable of guiding one’s own behavior on the basis of reasons, directives and principles. • As Kant puts it: “Everything in nature works in accordance with laws. Only a rational being has the power to act in accordance with his idea of laws-that is, in accordance with principles-and only so has he a will.” • So To be rational is to act for reasons or by principle. • A reason: a consideration that weighs in favor of or supports doing something. • A principle: the same thing as a law. • It is just a rule of action…

6. BDI • A rational agent has beliefs, desires, intentions and a will. • Beliefs, Desires & Intentions: • We form desires or wants for things, • We form beliefs on how to satisfy those wants, • And we form intentions on how to satisfy those desires. • We form a plan, given our beliefs, by which we will be able to satisfy the desire. • The Will: the capacity an agent has to act for reasons... • The will carries us from the intention to satisfy some desire, to actually satisfying that desire. It gets our feet moving. • It is the power that us rational beings have to get from reasons to action.

7. Kant’s freedom of the will • Freedom: • A person is free when bound only by her own will and not by the will of another. • We can be commanded only by our own wills. • Freedom as a first cause: • Freedom (and rationality) consists in seeking to be the first cause of one’s actions wholly and completely through the exercise of one’s own will. • Her actions then express her own will. • Internal authority: the authority of the principles binding her will is then also not external to her will. • Kant then give us the Categorical imperative as this binding principle.

8. The Categorical Imperative • Binding our will: So the Categorical imperative is supposed to bind our wills. • Binding us to being rational: The CI binds our wills by binding us to being rational. • So It provides us with a how to guide to being rational. • But is it rational to be rational? • Yes or No?

9. The Categorical Imperative • Kant called his Supreme principle of morality the Categorical Imperative, which he said was to be distinguished from a hypothetical imperative. • A Hypothetical imperative is conditional on some want or desire. • If you don’t have the relevant desire, then you aren’t directed to perform the action… • Doesn’t depend on desires: • it simply commands you to do X, no matter what. • Putting the right before the good: • Since the categorical imperative is categorical it commands you to act irrespective of the consequences of your actions. • This is what it means for Kant’s theory to be deontological and to put the right before the good…

10. The Categorical Imperative • So what is the categorical imperative? • He gives a number of different formulations… • We will focus on the one known as the formula of the end in itself: • Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means but always at the same time as an end.

11. The Formula of the End in itself • The Categorical Imperative: • Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means but always at the same time as an end. • Means vs. Mere Means: Kant does not say that you should never use another person as a means! • We use people as a means for our own ends every day • In-N-Out example… • What he says is never treat yourself or any other person as a mere means. • So if you treat someone as a means make sure to treat her as an end in herself: • respect her as an agent with ends of her own. • Rational consent: • To determine if you are treating someone as a mere means you need ask only: Would this person rationally consent to being treated as such?

12. The Scapegoat • So for Kant, what’s wrong with punishing an innocent person to prevent a riot? • A Consequentialist moral theory might permit or even require you to punish an innocent person in order to prevent a riot and thereby save many other lives. • The Formula of the End in itself explains what is wrong with punishing someone who is innocent merely to prevent a riot: • You are not punishing him because he deserves punishment, • You are using him as a mere means to save others.

13. The perfect and imperfect duties • Duties: From the Formula of the end in itself several duties are derived: • More specific formulations of the categorical imperative… • Perfect and Imperfect Duties: He divided the duties into two groups. • The perfect duties: duties of justice. • Prohibited: They are necessary and ought never be violated. • The perfect duties include: • The duty one has to never harm herself or anyone else. • The duty one has to others to keep her promises and to tell the truth. • The imperfect duties: duties of beneficence, charity and kindness. • Not prohibited: Violating these duties isn’t prohibited. • The imperfect duties include: • The duty one has to others to assist those in need. • The duty one has to oneself to develop her talents. • Perfect duties are said to trump imperfect duties…

14. The Good Will • The Good will: Kant thought that “the only thing good without qualification is a good will”. • To be good without qualification is to be good in and of itself. • To have a good will: • the same thing as having a good moral character, which is just to act for the right reasons. • For Kant, to act for the right reasons one must act always for the sake of duty. • One acts for the sake of duty when: • she performs some action X and her reason for performing x is merely that it is what the moral law prescribes her to do. • What is required in performing X is: • one’s action be motivated by the moral law & • that no other motives, even love or friendship, cooperate. • The good person: • What makes a good person good is his possession of a will that is determined by the moral law…

15. Kant’s theory in action • In-N-Out Example: • Desire: I’m hungry for In-N-Out • Belief: • Intention: • Willing: • False Promises: • A friend asks me to keep a secret • Desire: I want to break the promise… • Belief: • Intention: • Why can’t I tell her?

16. To sum up • So the big picture for the Kantian looks like this: • Following the Categorical Imperative gets you the following: • Freedom, Rightness and Rationality… • But following the categorical imperative isn’t enough: • To be a truly good person you must do what the categorical imperative tells you to do just because it is Right…

17. Problems for Kant’s Theory So why we can’t just opt out of rationality: Live like the animals: Even though we can be bound by the moral law, and in so being exercise our capacity as a rational agent, why not just live like the animals? Why be rational at all? Plausible responses: There is value in rationality…

18. Is Rationality the correct starting point? • Is Rationality the correct starting point? • Kant’s view of morality stems from the notion of a person. • Why should this be our starting point? • Hume’s response to Kant: • Reason is slave to the passions • A Kantian response: • Aren’t rational creatures morally privileged?

19. Problems for Kant’s theory • Acting for the sake of the moral law: • makes the agent seem cold and heartless. • Say you go to visit your friend in the hospital. • She is very sick. So you bring her some flowers and a get well card. You say hello and chat with her for a while. Then you stay for a bit while she sleeps. • For a Kantian, for the visitation to be a truly good action your motive for visiting your friend must be that it is your moral duty to do so. • But don’t you really go for the friendship and loyalty you have for your friend? • So maybe the Kantian picture gets moral motivation all wrong?

20. Final thoughts? • Final thoughts on Kant: • Remaining objections… • The completeness of the picture… • Other thoughts…
