The perennial quest for a framework to guide human action and define the good life has yielded diverse philosophical approaches. Among these, Natural Law theory and Virtue Ethics stand out as enduring traditions with distinct origins but notable common ground. Natural Law, often associated with figures like Thomas Aquinas, posits that morality is discernible through reason, inherent in the natural order of things, and aimed at promoting human flourishing. Virtue Ethics, tracing its roots to Aristotle, focuses on the cultivation of character, emphasizing that right action flows from a virtuous agent. While Natural Law offers a more objective, deontological-style guidance based on inherent human purposes, and Virtue Ethics prioritizes character development and practical wisdom, a closer examination reveals significant points of convergence, particularly in their shared emphasis on human nature and the pursuit of eudaimonia, or genuine well-being.
A key area of overlap lies in their shared understanding of human nature as a foundation for morality. Natural Law theory, in its Thomistic formulation, argues that God's eternal law is imprinted on creation, and humans, possessing reason, can access this law. This includes understanding our inherent inclinations towards self-preservation, procreation, knowledge, and social living. Acting in accordance with these inclinations, as guided by reason, is considered acting according to nature and thus morally good. For instance, the Natural Law prohibition against murder stems from the inclination towards self-preservation, a fundamental aspect of human nature. Similarly, Virtue Ethics, particularly Aristotle's, also begins with an account of human nature. Aristotle argues that every being has a function (ergon), and for humans, this function is rational activity. Flourishing, or eudaimonia, is achieved by performing this function well, which means developing and exercising virtues like courage, temperance, and justice. Both traditions, therefore, ground their ethical systems in an understanding of what it means to be human and what constitutes a good human life, rather than solely on abstract rules or divine command.
Despite this shared foundation, their approaches to ethical guidance diverge. Natural Law offers a more prescriptive set of principles. It suggests that certain actions are intrinsically right or wrong because they either promote or hinder the fulfillment of natural inclinations. For example, the Natural Law tradition generally holds that certain sexual acts are unnatural and thus immoral because they do not align with the procreative purpose of sexuality, even if they are pleasurable or consensual. This provides a relatively clear, albeit sometimes debated, standard for judging actions. Virtue Ethics, conversely, focuses on the agent's character. It asks not just "What is the right thing to do?" but "What kind of person should I be?" The emphasis is on developing virtues, which are stable dispositions to act well. A courageous person, for instance, acts courageously not because of a rigid rule, but because courage is part of their character, enabling them to face fear appropriately in various situations. Practical wisdom (phronesis) is crucial here, allowing the virtuous individual to discern the right course of action in complex, nuanced circumstances, recognizing that rigid rules might not always apply.
However, the distinction is not absolute, and the two traditions can be seen as complementary. Virtue Ethics, in emphasizing practical wisdom, implicitly acknowledges the importance of discerning what actions are conducive to flourishing. This discernment can be informed by the principles identified by Natural Law. For example, a virtuous person cultivating justice would likely recognize the importance of respecting the Natural Law principle of not harming others, as this is fundamental to a well-ordered society and individual well-being. Conversely, Natural Law's focus on inherent purposes can be understood as providing a framework for what virtues are necessary to achieve those purposes. To live a life of reason and sociality, as Natural Law suggests are fundamental goods, one needs virtues like temperance, justice, and wisdom. The development of these virtues, as advocated by Virtue Ethics, is precisely what allows individuals to successfully live in accordance with Natural Law and achieve genuine flourishing. Thus, while Natural Law provides a blueprint for a good life based on human nature, Virtue Ethics offers the psychological and characterological tools to inhabit that blueprint.
In conclusion, Natural Law theory and Virtue Ethics, though distinct in their primary focus and method, share a profound connection rooted in their commitment to human nature and flourishing. Natural Law offers a rational account of inherent goods and principles, while Virtue Ethics centers on the cultivation of character and practical wisdom to achieve a good life. Rather than being mutually exclusive, they can be viewed as offering complementary perspectives: Natural Law identifies the ends of human existence, and Virtue Ethics provides the means, through character development, to achieve those ends. Together, they offer a robust framework for understanding morality and living a fulfilling human life.
