5 Mill s Empiricism a. Visible = df able to be seen b. Desirable = df able to be desired c. valuable = df what we desire G.E. Moore s Objection THE NATURALISTIC FALLACY Value cannot be defined in naturalistic terms (e.g., pleasure, what we desire). Any naturalistic definition of value is not true by definition. Whether the definition is true is an open question. So whether value is what we desire is also an open question.

6 Immanuel Kant ( ) He s technical and complex. He s enormously influential. Timmons / Shafer-Landau One of the greatest philosophers in history, with major contributions in epistemology, metaphysics, ethics, the philosophy of religion, aesthetics, and many other areas.

7 Bentham s source of moral salience: sentience (pleasure) Kant s source of moral salience: agency (rationality)

8 Bentham s source of moral salience: sentience Kant s source of moral salience: agency Moral Claims: empirical knowable a posteriori contingent Moral Claims: non-empirical knowable a priori necessary

9 Agents make rules for themselves (call these maxims). This ability is known as autonomy.

13 Kant s Theory of Value

14 The Good The Right Good Will The Categorical Imperative

15 Agency is not good without qualification Unconditional: Good without qualification / in all circumstances. Vs. Conditional: Good only with qualification / in some circumstances.

16 Kant s Theory of the Good Nothing in the world indeed nothing even beyond the world- can possible be conceived which could be called good without qualification except a good will.

17 KANT S THREE PROPOSITIONS 1. to have moral worth an action must be done from duty 2. An action performed from duty does not have its moral worth in the purpose which is to be achieved through it but in the maxim by which it is determined. 3. Duty is the necessity of an action executed from respect for the law.

18 Persons who help or benefit others because they have a spontaneous inclination toward sympathy (or benevolence or generosity) are, like the shopkeeper, doing what they want to do and not acting out of duty; thus their actions have no real moral worth

19 An act done from duty. vs. An act done merely in accordance with duty. An act done merely in accordance with duty (with sympathy/inclination). vs. An act done merely in accordance with duty (with no sympathy/inclination).

20 The person worthy of moral esteem is the one who has no desire or inclination at all to help anyone but who helps others out of moral duty alone

21 Bob visits his friend in the hospital and initially the friend is very grateful until she realizes that Bob does this act because he feels that it is his duty, not because he cares for the individual in the hospital bed. Is it morally important that Bob acts out of a sense of duty? Is there something missing in his motivational set? (Adapted from Michael Stocker s Moral Schizophrenia) Huckleberry Finn helps his friend, Jim, escape slavery. As a result, Huck experiences pangs of extreme guilt. This is because he believes that he violating his duty, i.e., the racist norms of the 19 th century rural American South. Is it morally important that Huck Finn acts against his sense of duty? Is there something missing in his motivational set? (Adapted from Jonathon Bennett s The Conscience of Huckleberry Finn)

22 Maxim: principle of volition or reason for action. Hypothetical Imperatives claim that a possible action is necessary as a means to the attainment of something one wants. A Categorical Imperative represents an action as objectively necessary, without regard to a further end.

23 Utilitarianism Theory of value: pleasure is the only intrinsic good. Right action: consequences are the sole determinate. Motivation: the agent s maxim is irrelevant to the action s moral worth. Kantianism Theory of value: the good will is the only unconditional good. Right action: consequences are irrelevant. Motivation: the agent s maxim is the sole determinant of moral worth.

24 The Formulation of Universal Law

25 Act only according to that maxim by which you can at the same time will that it should become a universal law of nature. An action is right if and only if one can (a) consistently conceive of everyone adopting and acting on the general policy of one s action, and also (b) consistently will that everyone act on that maxim (Timmons, 17).

26 Imperatives An imperative being a command of reason, holds for any rational being. Hypothetical Imperative A maxim which assumes an end and commands an action as a means to that end. If you want x, then you ought to do y. E.g., If you want do to well on the Kant quiz this week, you should study very hard.

27 Imperatives An imperative being a command of reason, holds for any rational being. Categorical Imperative A maxim demanding the performance of actions and the settings of ends without being conditional on any prior setting of an end. Don t do X, period! E.g., Don t torture puppies for fun, period!

28 Moral duties are imperative and apply to all rational beings as such. Therefore Moral principles are necessary. Moral principles are nonempirical / knowable a priori. Moral principles are universal: they must give the same kind of answer to each rational being placed in the same kind of situation. Categorical Imperative A maxim demanding the performance of actions and the settings of ends without being conditional on any prior setting of an end. Don t do X, period! E.g., Don t torture puppies for fun, period!

30 The Formulation An action is right if and only if one can (a) consistently conceive of everyone adopting and acting on the general policy of one s action, and also (b) consistently will that everyone act on that maxim (Timmons, 17). How does it work? Step-one: Take a maxim. Step-two: Universalize it. Step-three: Run a consistency test. Contradiction in Conception Can you conceive of a world in which this maxim is universally followed? Contradiction in Will Can you rationally will for this world to exist?

31 A universal law is a sentence that is always true or always followed by everyone. When you will your maxim to become universal law, formulate it is as rule or general principle, which is law-like such that any rational agent can act on it. Consistency test: you may not be able to will your maxim to become a universal law if it entails a formal contradiction A formal contradiction: holding P and not-p (e.g., a round-square). How does it work? Step-one: Take a maxim. Step-two: Universalize it. Step-three: Run a consistency test. Contradiction in Conception Can you conceive of a world in which this maxim is universally followed? Contradiction in Will Can you rationally will for this world to exist?

32 For my lie to work, I need other people to believe my lie. I thus need lies to be exceptional, and most people to tell the truth.

33 1. That most people keep their promises (so the institution of promise making exists). 2. That I don t have to keep my promise (so the institution of promise making does not exist).

34 1. You should only do those actions that conform to rules that you could will to be adopted universally. 2. If you were to make an insincere promise, you would be following the rule: when I believe myself to be in need of money, I shall borrow money and promise to repay it, even though I have no intention of repaying it. 3. This rule could not be adopted universally, because it would be self-contradicting. 4. Therefore, you ought not to make lying promises.

35 Group Exercise I eat a meal at a restaurant. After I finish, I wait until the waiter s attention is distracted, and leave without paying. I am not caught. What reasons would a Kantian give to explain why my action is morally wrong? In your answer, be sure to explain the maxim this action exemplifies, the universal law, and how the universal law entails a formal contradiction. How does it work? Step-one: Take a maxim. Step-two: Universalize it. Step-three: Run a consistency test. Contradiction in Conception Can you conceive of a world in which this maxim is universally followed? Contradiction in Will Can you rationally will for this world to exist?

36 Perfect Duties A perfect duty is one that strictly requires certain specific actions, with no choice or leeway (B/B, 358). Determined by the contradiction in conception test. E.g., The lying promise Imperfect Duties an imperfect duty is one that can be fulfilled in several different ways, among which the agent may choose, and thus no one of which is strictly required (B/B, 358). Determined by the contradiction in will test. E.g., The duty to render mutual aid.

37 1. You should only do those actions that conform to rules that you could will to be adopted universally. 2. If you were to refuse to aid others in need, you would be following the rule: when I believe others to be in need I will not aid them. 3. This rule could not be willed universally, because it would defeat the rational will s wider purposes. (A universal law would imply that others not help you when you are in need.) 4. Therefore, you should accept the (imperfect) duty to aid others in need.

38 The Formulation of Universal Law

39 Absolute Duty: a moral obligation that cannot be overridden. Prima Facie Duty: a moral obligation that can be overridden. Problem: You have Nazi s at your door asking, Do you know where any Jews are? Does Kant give us the right answer?

40 The Sneaky Maxim Maker Objection MacIntyre: the Categorical Imperative imposes restrictions only on those insufficiently equipped with ingenuity (A Short History of Ethics, 198). Is universalizability vacuous and conservative?

41 [Kant] fails, almost grotesquely, to show that there would be any contradiction, any logical (not to say physical) impossibility in the adoption by all rational beings of the most outrageously immoral rules of conduct All he shows is that the consequences of their universal adoption would be such as no one would choose to incur (Utilitarianism, Ch. 3). Is Kant guilty of covert consequentialism?

42 The Formulation of Humanity

43 Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. An action is right if and only if (and because) the action treats persons (including oneself) as an ends in themselves and not as a mere means (Timmons, 16).

44 Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. An action is right if and only if (and because) the action treats persons (including oneself) as an ends in themselves and not as a mere means (Timmons, 16). Clarifications mere means? Humanity = df Agency

45 Agents can make rules for themselves (maxims). This ability is known as autonomy.

46 HETERONOMY AUTONOMY

48 HUMANITY FORMULATION Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. Treating as a means: dealing with someone so as to achieve your goals. Treating as an end: treating someone with the respect he or she deserves.

49 HUMANITY FORMULATION Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. Negative Aspect: never as a mere means Positive Aspect: always as an ends

50 HUMANITY FORMULATION Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. Negative Aspect: never as a mere means Standard violations: Deception Coercion Paternalism Manipulation

51 HUMANITY FORMULATION Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. Positive Aspect: always as an ends Respect the ends of others!

52 HUMANITY FORMULATION Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. Interpretations: 1. Personal Tone 2. Actual Consent 3. Hypothetical Consent 4. Possible Consent *From Onora O Neil

58 Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. a.animal Rights b.trolley Cases c.reluctant Donor d.huckleberry Finn e.nazi at the door f. Suicide / Euthanasia g.prostitution / Pornography

59 The Basic Problem The notion of treating someone as an end is vague, and so the principle is difficult to apply. The principle fails to give us good advice about how to determine what people deserve.

60 The principle assumes that we are genuinely autonomous, but that assumption may be false. The Argument against Autonomy 1) Either our choices are necessitated, or they are not. 2) If they are necessitated, then they are out of our control, and so we lack autonomy. 3) If they are not necessitated, then they are random, and so we lack autonomy. 4) Therefore, we lack autonomy.

61 The principle assumes that the morality of our actions depends only on what we can autonomously control, but the existence of moral luck calls this into question. Moral luck: cases in which the morality of an action depends on factors outside of our control.

62

63

64 The principle cannot explain why those who lack rationality and autonomy are deserving of respect. The Argument against Animals 1) If the principle of humanity is true, then animals have no rights. 2) If animals have no rights, then it is morally acceptable to torture them. 3) Therefore, if the principle of humanity is true, then it is morally acceptable to torture animals. 4) It isn t morally acceptable to torture animals. 5) Therefore, the principle of humanity is false.

65 The Formulation of The Kingdom of Ends

66 Big picture Formula of Universal Law Act only according to that maxim by which you can at the same time will that it should become a universal law of nature. Objections 1. Rigorism 2. Vacuity 3. Covert Consequentialism

67 Big picture Formula of Universal Law Act only according to that maxim by which you can at the same time will that it should become a universal law of nature. Question What are the rational will s wider purposes?

68 Big picture Formula of Humanity Act so that you treat humanity, whether in your own person or in that of another, always as an end and never as a means only. Question How do you respect the ends of others?

69 Big picture The Kingdom of Ends So act as if you, by your own maxims, were at all times a legislative member in the universal realm of ends. Kant s CI Kingdom of ends A systematic union of rational beings by common objective laws. Self-Legislation We, as rational agents, legislate the law to which we are subject. Co-Legislation Our maxims must be consistent with the idea of the will of every rational being as a will giving universal law.

70 a) It is individually rational not to cooperate. b) It is collectively rational to cooperate.

71 Kant and Hobbes agree that we are rationally required to leave the state of nature and submit to a coercive authority in order to adjudicate between conflicts of individual interests. For Kant, the rationale is autonomous. For Hobbes, the rational is heteronomous.

73 Discussion Question The Happy Slave Question (about Autonomy) Is it morally permissible to (happily) consent to a life of slavery? (a)how would Kant answer this question? (b)how would Mill answer this question? (c)how would Hobbes answer this question? (d)in your assessment, which answer is better and why?
