1Deontology: the Ethics of Duty Immanuel KantDeontology:the Ethics of Duty
2Kant’s Moral Theory Historical Background Immanuel Kant (1724-1804) The concept of the “good will”The concept of dutyThree principlesThe Categorical ImperativeThe Hypothetical ImperativeAutonomy and Heteronomy of willKant on the concept of respectContemporary Deontologists
3Good WillAn action has moral worth only when performed by an agent who possesses a good willAn agent has a good will only if moral obligation based on a universally valid norm is the action’s sole motiveFirst Section, first 3 paragraphs
4DutyAll persons must act not only in accordance with, but for the sake of, obligationA person’s motive for acting must rest in a recognition that what he or she intends is demanded by an obligationp. 2, second paragraphp. 3, last paragraph
5Three Principles“An act must be done from obligation in order to have moral worth.”“An action’s moral value is due to the maxim from which it is performed, rather than to its success in realizing some desired end or purpose.” – motive of benevolence is rejected as morally unworthy“Obligation is the necessity of an action performed from respect for law.”
6An action has moral worth only if a morally valid rule of obligation determines that action Even a motive of benevolence is rejected as morally unworthy, unless there is an accompanying motive of obligationNecessity comes from laws, not from mere subjective maxims. There must be an objective principle underlying willing, one that all rational agents would accept
7Categorical Imperative The supreme principle or moral law.Every moral agent recognizes whenever accepting an action as morally obligatoryWhy is the categorical imperative “imperative”?Human beings are imperfect creatures and hence need rules imposed uponThese rules enjoin us to do or not to do something thus we conceive them as necessitating our action
8Categorical Imperative Act only in such a way in which the maxim of action can be rationally willed as a universal lawIt requires unconditional conformity by all rational beings, regardless of circumstancesIs unconditional and applicable at all times4 examples, p. 9
9Hypothetical Imperative “If I want to obtain e, then I must obtain means m.”E.g. “If I want to buy a house, then I must work hard to make enough money for a down payment.”
11LawRefers to the rules of conduct that rational beings lay down for themselves in the light of reason.
12Categorical Imperatives: Universality “Always act in such a way that the maxim of your action can be willed as a universal law of humanity.”--Immanuel Kant
13Categorical Imperative: Publicity Always act in such a way that you would not be embarrassed to have your actions described on the front page of The New York Times.
14Lying Is it possible to universalize a maxim that permits lying? What is the maxim?It’s ok to cheat when you want/need to?Can this consistently be willed as a universal law?No, it undermines itself, destroying the rational expectation of trust upon which it depends.
15Kant on Respect“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.”
16Kant on Respecting Persons Kant brought the notion of respect to the center of moral philosophy for the first time.To respect people is to treat them as ends in themselves. He sees people as autonomous, i.e., as giving the moral law to themselves.The opposite of respecting people is treating them as mere means to an end.
17Using People as Mere Means The Tuskegee Syphilis ExperimentsMore than four hundred African American men infected with syphilis went untreated for four decades in a project sponsored by the governmentContinued until 1972
18Autonomy and Heteronomy Autonomy of will is present when one knowingly governs oneself in accordance with universally valid moral principlesHeteronomy of will: the will’s determination by persons or conditions other than oneself. (“heteronomy”: any source of determining influence or control over the will, internal or external, except a determination of the will by moral principles)
19The autonomy of the moral agent is to recognize that external authority, even if divine, can provide no criterion for morality; only our own reason that we are taking to be ultimate authority
20Reading: Fundamental Principles of the Metaphysic of Morals The Good Will as “good without qualification”Acting from duty vs. acting from inclinationDuty as the necessity of an action done out of respect for the lawThe Categorical Imperative – first formulationHypothetical vs. categorical imperativesPrudence vs. moralityApplying the categorical imperative: four examplesPersons as ends in themselvesThe Categorical Imperative – second formulationThe four examples again
21DeontologistsAn act is right if, and only if, it conforms to the relevant moral obligation; and it is wrong if, and only if, it violates the relevant moral obligationThey argue that the consequences of an action are irrelevant to moral evaluationThey emphasize that the value of an action lies in motive, especially motives of obligation
22Consequences of Kantian Ethics The dignity of the human being is to be found in his moral responsibility (freedom)The dignity of the human being does not require another foundation, i.e. theological or natureThe dignity of the person is the unconditional (i.e. metaphysical) groundMorality reveals the ultimate metaphysical depth of the human being. To be human is to act morally.One discovers the source of our humanity in the ability to act morally, i.e., to accept the moral imperative as finite, yet grounded in an absolute source, human freedom
