Ethics Skill
Master ethical theory: metaethics (nature of morality), normative ethics (what we ought to do), and applied ethics (specific issues).
Structure of Ethics
ETHICAL THEORY ══════════════
METAETHICS ├── What is the nature of moral claims? ├── Are there moral facts? └── Can we have moral knowledge?
NORMATIVE ETHICS ├── What makes actions right/wrong? ├── Consequentialism, deontology, virtue ethics └── General moral principles
APPLIED ETHICS ├── Specific moral issues ├── Bioethics, environmental ethics, business ethics └── Applying principles to cases
Metaethics
Moral Realism vs. Anti-Realism
Moral Realism:
-
There are objective moral facts
-
Moral claims are truth-apt
-
Some moral beliefs are true
Moral Anti-Realism:
-
Error theory: Moral claims are false
-
Non-cognitivism: Moral claims aren't truth-apt
-
Relativism: Truth relative to culture/individual
Non-Cognitivism
Emotivism (Ayer, Stevenson):
-
"X is wrong" = "Boo X!"
-
Moral claims express attitudes, not beliefs
Prescriptivism (Hare):
-
"X is wrong" = "Don't do X!"
-
Moral claims are universal prescriptions
Expressivism (Blackburn, Gibbard):
-
Moral claims express non-cognitive states
-
But can still be "true" in a deflated sense
Moral Epistemology
Intuitionism: We directly perceive moral truths Rationalism: Moral truths knowable a priori Naturalism: Moral facts = natural facts Constructivism: Moral truths constructed by rational procedures
Normative Ethics
Consequentialism
Core Idea: Actions are right if they produce best outcomes
CONSEQUENTIALIST THEORIES ═════════════════════════
UTILITARIANISM ├── Maximize happiness/pleasure ├── Bentham: Quantity of pleasure ├── Mill: Quality matters too └── Hedonistic vs. preference utilitarianism
ACT UTILITARIANISM ├── Each act evaluated by its consequences └── Problems: demanding, counter-intuitive
RULE UTILITARIANISM ├── Follow rules that maximize utility └── Handles some objections
CONSEQUENTIALIST FORMULA: Right action = Action that maximizes good outcomes
Objections:
-
Integrity (Williams): Alienates us from our projects
-
Justice: Might justify punishing innocents
-
Demandingness: Requires constant maximization
-
Calculation: Impossible to know all consequences
Deontology
Core Idea: Actions have intrinsic rightness/wrongness regardless of consequences
KANTIAN ETHICS ══════════════
CATEGORICAL IMPERATIVE (CI) ├── Formula of Universal Law │ └── Act only on maxims you can will as universal laws ├── Formula of Humanity │ └── Treat humanity never merely as means └── Formula of Autonomy └── Act as if legislating for a kingdom of ends
APPLYING THE CI:
- Formulate maxim (e.g., "Lie when convenient")
- Universalize: What if everyone acted this way?
- If contradiction (logical or practical), action is wrong
- Lying universalized → No trust → Lying pointless ∴ Lying is wrong
Deontological Constraints:
-
Some acts wrong regardless of consequences
-
Negative duties (don't harm) stronger than positive (help)
-
Agent-relative: My killing is worse than allowing death
Virtue Ethics
Core Idea: Focus on character, not acts or rules
VIRTUE ETHICS ═════════════
EUDAIMONIA (Flourishing) ├── The good life; well-being ├── Achieved through virtue └── Not just feeling good
VIRTUES ├── Character traits that promote flourishing ├── Courage, temperance, justice, wisdom ├── Acquired through habituation └── Mean between extremes
PHRONESIS (Practical Wisdom) ├── Knowing what virtue requires in situations ├── Cannot be reduced to rules └── Developed through experience
VIRTUOUS PERSON AS STANDARD: Right action = What the virtuous person would do
Neo-Aristotelian: MacIntyre, Foot, Hursthouse Challenges: Action guidance, moral disagreement, relativism
Comparison
Theory What's Primary Right Action
Consequentialism Good outcomes Maximizes good
Deontology Right acts/duties Follows rules
Virtue Ethics Good character What virtuous do
Thought Experiments
Trolley Problems
TROLLEY CASES ═════════════
SWITCH: Trolley heading to kill 5. Flip switch → diverts to kill 1. Most say: Permissible
FOOTBRIDGE: Trolley heading to kill 5. Push large man off bridge to stop trolley. Most say: Impermissible
WHY THE DIFFERENCE? ├── Doing vs. allowing ├── Intended vs. foreseen (Double Effect) ├── Using person as means └── Physical contact
Experience Machine
Nozick: Would you plug into a machine that simulates perfect happiness?
-
Most say no → Pleasure isn't everything
-
Authenticity, achievement, reality matter
Violinist
Thomson: You wake up connected to a famous violinist who needs your kidneys.
-
Argues: Even if fetus is person, abortion can be permissible
-
Your body, your choice
