In the history of ethics and moral philosophy, few philosophers wrote accessible theories lay people and non-specialists could understand. Ross's straightforward, intuitive approach makes him a favorite for courses in introductory ethics, medical ethics and legal ethics. Ross maintains significance in the field as a result of his Aristotle translations, contributions to Kant's ethics and commitment to conceptualizing the good life.
Ross's prima facie duties constitute a development of Kant's moral theory and a departure. Rather than accepting Kant's abstractions, Ross considers human intuition and emotional attachment. He uses Aristotle's conception of the flourishing life and H.A. Pritchard's intuitionism. Intuitionism allows Ross to develop ethical duties without reason-based defense. By definition, prima facie, intuitive duties hold regardless of empirical evidence. Ross draws from many sources and discourages reliance on one religious or philosophical system.
Duties of fidelity involve the promises you make to friends and loved ones. By taking these promises seriously and following through, you uphold your duties of fidelity. Such promises often materialize explicitly, meaning that you acknowledge them outright. Implicit promises hold as well. For example, a spouse may defy your expectations and have an extramarital affair. This constitutes a transgression of fidelity that hurts one or more other people.
Duties of reparation involve your responsibilities to make amends with people you hurt in the past. For example, you should replace property or resources you damaged or wasted in the past. If you caused previous emotional pain, apologize to those whom you hurt. If the person wishes not to hear from you, respect her decision. If you remain in a relationship with the person, abandon the hurtful behavior.
Duties of gratitude invoke your responsibility to repay the kindness or generosity of others. Gratitude sometimes involves repayment of material assets, but material repayment can sometimes prove inappropriate. When someone gives a generous gift, you need not reciprocate exactly. Express thanks and maintain a meaningful relationship that brings you opportunities to give back materially or emotionally. Express gratitude for emotional giving and reciprocate, as those who supply support and comradeship enrich your life.
Duties of justice in part imply an imperative to distribute goods and services fairly. Even so, Ross supports the use of common sense rather than exact redistribution. Reward those who perform tasks that benefit society, such as medicine or teaching. Distribute necessities so that all have an opportunity to flourish. In families, treat children equally within the realm of common sense. If one child steals from or abuses you, invest emotional or material resources in the others.
Duties of beneficence, or kindness, require that you treat others in ways that help them access the good life. Perform thoughtful acts that improve the well-being of others. Give liberally to people in need. Stand for the well-being of the collective society without losing the ability to express kindness and compassion in personal relationships. In close relationships, behave thoughtfully and generously. The practice of beneficence benefits society as well as the people you love.
The duties of self-improvement posit self-care as important ethical behavior. Perform acts that make you a better person. Study diligently. Work hard. Learn about your talents so you may advance within your career. Practice ingenuity and determine creative solutions to difficult problems. Earn enough resources to allow you and your family to flourish, but use your talents and surplus wealth to benefit the common good.
The duties of non-malfeasance, or non-harm, prohibit deliberate actions meant to injure yourself or others. Refrain from cruelty, and treat others as valued members of society. Do not hurt others, but also make an effort to help others avoid hurt. Educate yourself about social inequality and poverty so you may work to prevent people from the harm of starvation. Teach children not to enter cars driven by strangers to help them avoid future hurt.
Sometimes Ross's seven prima facie duties receive criticism for representing a mere typology or list. That is, Ross provides a list of what he sees as the seven most important and self-evident ethical duties, but fails to integrate them into a cohesive theoretical approach. Philosophers of history, for example, argue that a more historical approach which increases the depth of engagement with past thinkers could improve the theory. Feminist philosophers call for a more broad and inclusive ethics.
