Lecture Content
I. Why Ethical Frameworks Matter in Medicine
Physicians face moral dilemmas routinely: questions about resource allocation, end-of-life decisions, truth-telling, and confidentiality breaches arise in everyday practice. Ethical frameworks provide structured ways to reason through these dilemmas rather than relying on gut instinct alone. No framework gives a "right answer" in every case, but each illuminates different aspects of a problem. The goal is not to pick one theory and apply it rigidly but to develop fluency in multiple perspectives, enabling richer and more defensible moral reasoning.
II. Deontology (Duty-Based Ethics)
Deontology holds that morality is about following rules or duties, regardless of consequences. Its most influential proponent was Immanuel Kant (1724-1804), who formulated the Categorical Imperative in two key versions. The first formulation instructs: "Act only according to that maxim by which you can at the same time will that it should become a universal law." The test here is whether everyone could do what you are about to do without contradiction. The second formulation demands: "Treat humanity, whether in your own person or in that of another, always as an end and never merely as a means." In other words, persons possess intrinsic dignity and cannot be used merely as tools for others' benefit.
Several key features define deontological thinking. Actions are right or wrong in themselves, not because of their outcomes. Moral rules are understood as absolute and universal -- "do not lie" and "do not kill" apply without exception. Autonomy and human dignity serve as foundational commitments.
In medicine, deontology has powerful applications. Informed consent reflects the deontological principle that patients must never be deceived or manipulated, because they are ends in themselves. A Kantian physician must always tell the truth, even if the truth causes distress. In research ethics, using patients merely as experimental subjects without their consent violates the categorical imperative.
Deontology's strengths include providing clear, unwavering moral rules, protecting individual rights and dignity, and guarding against the instrumentalization of persons. Its limitations are equally notable: it can be rigid, refusing exceptions even when consequences are catastrophic. Rules can conflict with one another -- for instance, the duty to tell the truth may clash with the duty to prevent harm -- and the theory offers no clear method for determining which duty takes priority.

Decision path 1: "Is there a moral duty to tell the truth? YES -> Tell the patient the truth, regardless of consequences." Decision path 2: "Would I want this action to be a universal law? (Can I will that all physicians always tell the truth?) YES -> Truth-telling is morally required." A side note reads: "The outcome (patient distress, hope, etc.) is morally irrelevant to the decision."</image>
III. Utilitarianism (Consequentialist Ethics)
Utilitarianism takes the opposite approach: the morally right action is the one that produces the greatest good for the greatest number. Jeremy Bentham (1748-1832) articulated "the greatest happiness principle," treating pleasure and pain as the currency of morality and developing the hedonic calculus to measure them. John Stuart Mill (1806-1873) refined the framework by distinguishing higher and lower pleasures and introducing rule utilitarianism, which evaluates rules rather than individual actions by their overall consequences.
The two main types of utilitarianism differ in their focus. Act utilitarianism evaluates each individual action by its consequences, while rule utilitarianism asks which rules, if generally adopted, would produce the greatest overall utility. In both versions, consequences are all that matter -- intentions and duties are morally irrelevant. All interests count equally, reflecting a commitment to impartiality. However, the framework requires predicting and comparing outcomes, which is often difficult in practice.
Utilitarianism finds natural application in medicine through public health policy, where vaccination mandates, quarantine, and fluoridation are justified by population-level benefit. Triage decisions allocate scarce resources such as ventilators and organs to maximize overall benefit. Cost-effectiveness analysis chooses treatments that provide the most quality-adjusted life years (QALYs) per dollar.
The framework is flexible and practical, adapts to circumstances, forces consideration of broader social consequences, and aligns well with public health reasoning. However, it can justify harming individuals for the greater good -- the notorious example of involuntary organ harvesting to save five lives illustrates this danger. Accurately predicting consequences is often difficult, individual rights and dignity can be violated, and minority interests may be sacrificed to benefit the majority.
IV. Virtue Ethics
Virtue ethics shifts the focus from rules and consequences to the character of the moral agent. Aristotle (384-322 BCE) is the foundational figure, and his concept of eudaimonia -- human flourishing -- stands as the highest good. Virtues are character traits or dispositions developed through practice and habituation, not simply rules to follow. The doctrine of the mean holds that virtues lie between extremes: courage, for instance, lies between cowardice and recklessness. Phronesis, or practical wisdom, is the ability to discern the right thing to do in particular situations, and it is perhaps the most important virtue of all.
Virtue ethics asks "What kind of person should I be?" rather than "What should I do?" It emphasizes moral development, mentorship, and role models, and it is inherently context-sensitive, recognizing that the right action depends on the situation and the moral agent's judgment. Edmund Pellegrino and David Thomasma identified several medical virtues: compassion (the capacity to suffer with the patient), trustworthiness (fidelity to the patient's well-being), integrity (consistency between one's values and actions), practical wisdom (good clinical and moral judgment), justice (fairness in the distribution of care), and courage (willingness to advocate for patients even at personal cost).
In medical education, virtue ethics supports character formation through role modeling and mentorship. It speaks to the "good doctor" question -- what traits and dispositions define excellent medical practice -- and it acknowledges that moral life is messy, requiring judgment rather than just rules. Its strengths include recognizing the importance of character and moral development, being flexible and context-sensitive, and aligning with how we actually think about good physicians. Its limitations include a lack of clear action-guidance in specific dilemmas, disagreement about which virtues matter most across different cultures and traditions, and a risk of moral relativism or elitism.

Row 2: Indifference -- Compassion -- Over-identification. Row 3: Rigidity -- Practical Wisdom -- Inconsistency. Row 4: Deception -- Honesty -- Brutal bluntness. Each virtue is shown as a balanced point between two extremes, with a brief clinical example beneath each row.</image>
V. Principlism: The Four Principles Approach
Principlism was developed by Tom Beauchamp and James Childress in their landmark work Principles of Biomedical Ethics, first published in 1979 and now in its eighth edition. It is not a standalone ethical theory but a practical framework that draws on multiple traditions. The four principles -- respect for autonomy, beneficence, non-maleficence, and justice -- will be covered in depth in Lecture 4. These principles are considered "prima facie," meaning they are binding unless overridden by a stronger competing principle in a specific case.
Principlism dominates bioethics for several reasons. It is accessible, requiring no commitment to a single philosophical theory. It is practical, providing a common vocabulary for interdisciplinary discussion. And it is flexible, allowing the balancing and weighing of principles in context.
Critics have called the four principles the "Georgetown mantra," arguing that the framework is too simple and masks deeper disagreements. It offers no method for resolving conflicts between principles. It may also be Western-centric, failing to capture moral values central to other cultures, such as community, harmony, or filial piety. And it lacks the depth and theoretical grounding of a full ethical theory.

VI. Integrating Frameworks in Clinical Practice
Real ethical dilemmas rarely map neatly onto one framework. Skilled moral reasoning involves identifying which frameworks are relevant to a given case, examining the dilemma from multiple perspectives, recognizing tensions and trade-offs explicitly, and making a judgment that one can articulate and defend. The rest of this course will apply these frameworks to specific issues in medicine, building the fluency that thoughtful clinical practice demands.
