📖Philosophical Texts Unit 10 – Ethics and Moral Philosophy
Ethics and moral philosophy explore the principles guiding human behavior and decision-making. This field examines concepts like deontology, consequentialism, and virtue ethics, which offer different approaches to determining right and wrong actions.
Key thinkers from ancient Greece to the present have shaped ethical theories. These include Aristotle's virtue ethics, Kant's categorical imperative, and Mill's utilitarianism. Contemporary debates address issues like effective altruism, AI ethics, and moral enhancement.
Ethics involves the study of moral principles, values, and standards that guide human behavior and decision-making
Morality refers to the set of beliefs, principles, and practices that distinguish right from wrong and good from bad
Deontology emphasizes the inherent rightness or wrongness of actions based on moral rules or duties (Kantian ethics)
Consequentialism judges the morality of an action based on its outcomes or consequences (utilitarianism)
Utilitarianism seeks to maximize overall happiness or well-being for the greatest number of people
Virtue ethics focuses on the moral character of the agent rather than the rightness or wrongness of specific actions
Moral relativism holds that moral judgments are relative to individual or cultural beliefs and practices
Moral absolutism maintains that there are universal, objective moral truths that apply to all people regardless of context
Ethical egoism asserts that moral agents ought to do what is in their own self-interest
Historical Context and Major Thinkers
Ancient Greek philosophers (Socrates, Plato, Aristotle) laid the foundations for Western moral philosophy
Socrates emphasized the importance of questioning societal norms and engaging in moral reasoning
Plato's theory of forms and the ideal of the philosopher-king influenced later ethical thought
Aristotle's virtue ethics focused on cultivating moral character through practical wisdom and moderation
Medieval Christian thinkers (Augustine, Aquinas) synthesized classical philosophy with religious doctrine
Enlightenment philosophers (Hume, Kant, Mill) developed systematic ethical theories based on reason and empiricism
David Hume's moral sentimentalism grounded ethics in human emotions and social utility
Immanuel Kant's deontological ethics emphasized the categorical imperative and respect for persons
John Stuart Mill's utilitarianism sought to maximize overall happiness and minimize suffering
20th-century philosophers (Rawls, MacIntyre, Nussbaum) engaged with contemporary moral issues and critiqued traditional theories
John Rawls' theory of justice as fairness aimed to establish principles for a just society
Alasdair MacIntyre's virtue ethics revived Aristotelian ideas in response to modern moral fragmentation
Martha Nussbaum's capabilities approach emphasized human flourishing and social justice
Ethical Theories and Frameworks
Normative ethics involves prescriptive theories about how one ought to act and what constitutes moral behavior
Deontological theories focus on the intrinsic rightness or wrongness of actions based on moral rules or duties
Kant's categorical imperative states that one should act only according to maxims that could become universal laws
The principle of double effect distinguishes between intended and foreseen consequences of an action
Consequentialist theories judge the morality of an action based on its outcomes or consequences
Act utilitarianism evaluates the morality of each individual action based on its utility (happiness or well-being produced)
Rule utilitarianism holds that the morally right action is the one that conforms to rules that maximize overall utility
Virtue ethics emphasizes the importance of moral character and the cultivation of virtues (courage, temperance, justice, wisdom)
Care ethics focuses on the interdependence of human relationships and the moral salience of attending to others' needs
Feminist ethics critiques traditional male-dominated moral theories and highlights the experiences of women and marginalized groups
Moral Dilemmas and Case Studies
The trolley problem presents a classic thought experiment in which one must choose between two morally fraught options
A runaway trolley is about to kill five people on the track ahead, but you can divert it to a side track where it will kill only one person
Variations of the trolley problem test our intuitions about the doctrine of double effect and the distinction between killing and letting die
The violinist analogy, proposed by Judith Jarvis Thomson, challenges the idea that abortion is always morally impermissible
It asks us to imagine being involuntarily connected to a famous violinist for nine months in order to save their life
The analogy suggests that the right to bodily autonomy may sometimes outweigh the duty to preserve life
The organ transplant scenario raises questions about the ethics of sacrificing one innocent person to save multiple lives
The Heinz dilemma, used in Lawrence Kohlberg's stages of moral development, presents a conflict between obeying the law and saving a life
The prisoner's dilemma illustrates the tension between individual and collective rationality in decision-making
Arguments and Counter-Arguments
The argument from marginal cases challenges the consistency of our moral consideration of humans and animals
If we grant moral status to humans with limited cognitive capacities, we should extend similar consideration to animals with comparable capacities
Critics argue that there are morally relevant differences between humans and animals that justify differential treatment
The non-identity problem suggests that we cannot harm future people by creating them with a low quality of life, since they would not have existed otherwise
This challenges the idea that we have moral obligations to future generations and raises questions about the ethics of reproduction
Responses to the non-identity problem appeal to impersonal or threshold conceptions of harm and the value of human existence
The demandingness objection claims that consequentialist theories (utilitarianism) are too demanding and fail to respect the separateness of persons
If we are always required to maximize overall utility, this may lead to extreme self-sacrifice and the neglect of personal projects and relationships
Consequentialists may bite the bullet and accept demandingness, or propose satisficing or hybrid theories that incorporate agent-relative permissions
The is-ought problem, raised by David Hume, challenges the logical derivation of prescriptive (ought) statements from purely descriptive (is) premises
This questions the foundations of moral realism and the possibility of deriving moral truths from empirical facts about the world
Responses to the is-ought problem may appeal to bridging principles, the practical necessity of moral norms, or non-cognitivist metaethical theories
Real-World Applications
Biomedical ethics addresses moral issues in healthcare, such as informed consent, euthanasia, and the allocation of scarce medical resources
The four principles of biomedical ethics (autonomy, non-maleficence, beneficence, justice) provide a framework for navigating complex medical decisions
The COVID-19 pandemic raised pressing questions about the ethics of lockdowns, vaccine distribution, and the balance of individual liberty and public health
Business ethics examines the moral dimensions of commercial activity, including corporate social responsibility, stakeholder theory, and ethical consumerism
Environmental ethics considers the moral status of non-human animals, ecosystems, and future generations in light of climate change and mass extinction
The land ethic, proposed by Aldo Leopold, calls for a holistic, ecological approach to moral consideration that includes the biotic community as a whole
The precautionary principle suggests that we have a duty to prevent harm when it is within our power to do so, even when some cause-and-effect relationships are not fully established
The ethics of war and peace addresses issues such as just war theory, pacifism, and the moral permissibility of military intervention
The doctrine of double effect is often invoked to justify collateral damage in war, while the principle of discrimination prohibits the intentional targeting of civilians
The ethics of emerging military technologies, such as autonomous weapons systems and cyberwarfare, pose new challenges for traditional just war theory
Contemporary Debates
The effective altruism movement applies consequentialist reasoning to charitable giving and career choice, emphasizing the importance of doing the most good possible
Effective altruists use evidence and reason to identify the most cost-effective ways to improve lives and reduce suffering on a global scale
Critics argue that effective altruism neglects the intrinsic value of personal relationships and local community engagement
The debate over moral enhancement considers whether we should use biotechnology to improve moral decision-making and behavior
Proponents argue that moral enhancement could help us overcome cognitive biases and reduce moral atrocities
Opponents worry that moral enhancement would undermine autonomy, authenticity, and the meaning of moral choice
The ethics of artificial intelligence (AI) examines the moral implications of developing and deploying AI systems
The value alignment problem highlights the challenge of ensuring that AI systems pursue goals that are consistent with human values
The question of moral agency and responsibility arises when considering the potential for autonomous AI systems to make moral decisions
The expanding circle of moral consideration traces the historical trend of extending moral status to an ever-wider range of beings
This raises questions about the moral status of non-human animals, potential extraterrestrial intelligence, and future digital minds
The long-termism perspective emphasizes the importance of shaping the far future and the vast potential for positive or negative outcomes
