This paper provides a comparative analysis of six prominent ethical theories: relativism, utilitarianism, egoism, Kant's Categorical Imperative, natural law/rights, and virtue ethics. For each theory, the paper explains the core premise, illustrates it with concrete examples, and evaluates its key strengths and weaknesses. The discussion highlights how these frameworks differ in their treatment of consequences, individual rights, cultural variation, and moral character. Together, the comparisons reveal the complexity of ethical decision-making and the trade-offs inherent in any single theoretical approach to determining right and wrong conduct.
The paper uses comparative analysis across a shared evaluative framework (strengths vs. weaknesses) to organize discussion of multiple theories. This technique allows readers to see not just what each theory claims, but how the theories relate to and differ from one another — for example, the explicit contrast drawn between Kant's deontological approach and utilitarian consequentialism using the same blanket-theft scenario.
The paper opens with a brief definitional introduction to ethics, then devotes one section to each of six theories in sequence: relativism, utilitarianism, egoism, Kant's theory, natural law/rights, and virtue ethics. Each section follows the same internal pattern — definition, example, strengths, weaknesses — before the paper closes with a works cited list. There is no separate conclusion section; the virtue ethics section serves as the final substantive discussion.
Ethics is an elusive concept that refers to the standards of what is right and what is wrong. Ethics is based on what people should do in terms of fairness, values, and obligations. Ethical theory provides the framework for better understanding the rationale behind ethics as a concept. This paper compares several of the more prominent theories, examining their strengths and weaknesses. These include: relativism, utilitarianism, egoism, Kant's theory, natural law and rights, and virtue ethics.
Ethical relativism surmises that there are no ethical absolutes when it comes to what is right and what is wrong. Instead, a group's ethics change and evolve with the social norms of its members, as well as with the cultural changes that occur over time. What is right for the individual is dependent on what the group feels is right. Slavery is a common example of ethical relativism ("What is Ethical Relativism?").
The primary strength of relativism is its ability to change with increased social awareness over time. Not so long ago, it was considered by many to be ethical to own slaves. Not only was it deemed acceptable to own slaves, but it was also perfectly acceptable to treat these human beings as sub-human — as chattel. However, as society recognized how inhumane this treatment was and how unfair it was to treat people like livestock simply because of their race, American culture changed and slavery was no longer deemed ethical.
The weakness of relativism lies in its inability to provide an accurate measure of a group's values and morals. Relying on an individual's or a society's moral choices is analogous to using one's sense of touch to determine the extent of a child's fever: when a child is sick, a more precise and consistent measurement is imperative. Our moral growth and the health of our collective conscience are also worthy of a more accurate gauge than subjective human feelings. Furthermore, conventional relativism implies that all one needs to do is convince a few close friends to engage in some activity viewed as immoral by the rest of society — and that previously unacceptable activity suddenly becomes ethically and morally correct ("What is Ethical Relativism?").
Utilitarianism was founded by Jeremy Bentham and John Stuart Mill (Weiss). Although there are a variety of interpretations of this ethical theory, the basic premise is that an action is deemed right or wrong based on its consequences. In utilitarianism, the end justifies the means. For this reason, the results of an action — regardless of the motivations or means behind it — are all that matter in determining whether the action is good or just. Utilitarianism further holds that an action is ethical if it provides the greatest good for the greatest number of people. Morally correct actions, according to this theory, are also those that offer a ratio of net benefits to costs greater than that of any other available alternative. Lastly, utilitarianism theorizes that an action is right if the benefits are the greatest for each individual and outweigh both the costs and the benefits of other solutions (MacKinnon).
The strength of utilitarianism lies in the altruistic nature of this theory. The pursuit of the "greater good" is a powerful motivator. Viewed from a wide perspective, it is easy to see the value in making decisions based on the amount of good they do for the greatest number of people. However, utilitarianism's weakness is that when one looks more closely at the individuals affected by a decision, there will inevitably be those who lose. This theory does not take into consideration the rights of the individual or the protection of minorities. There is no respect for human dignity in utilitarianism. In addition, it is not always possible to accurately anticipate the consequences of every decision.
