W.D. Ross on Prima Facie Duties and What Makes Acts Right

~5 min read 5 sections Philosophy · Moral Responsibility Decision Making
Abstract

This paper examines W.D. Ross's ethical theory as presented in his essay "What Makes Right Acts Right?" Ross rejects both Mill's utilitarianism and Kant's deontology, arguing that moral action cannot be reduced to a single good. Instead, he proposes a pluralistic framework built around prima facie (conditional) duties — obligations arising from promises, relationships, consequences, and past actions. The paper traces how Ross navigates the tension between rule-based and outcome-sensitive ethics, exploring the concept of "cases of conscience" where competing duties clash, and assessing why Ross's framework is considered more explanatorily powerful than utilitarian alternatives.

Key Takeaways
  • Introduction to Ross's Ethical Framework: Ross rejects single-principle ethics for pluralistic moral theory
  • Critique of Utilitarianism and Kantian Deontology: Ross argues utilitarianism lacks sufficient explanatory power
  • Prima Facie Duties and Conditional Obligation: Conditional duties arise from promises, relationships, and consequences
  • Consequence-Sensitivity and the Limits of Promise-Keeping: Ross concedes consequences can override promise-keeping duties
  • Cases of Conscience and Terminology: Clashing duties create conscience cases; prima facie terminology debated

What makes this paper effective

  • The paper clearly situates Ross's theory in relation to competing ethical frameworks (utilitarianism and Kantianism), giving the reader immediate comparative context.
  • It accurately tracks the internal tension within Ross's own position — acknowledging where he reluctantly concedes to consequence-sensitivity — rather than presenting his view as monolithic.
  • Specific examples, such as the promise-keeping and friend-versus-stranger scenarios, are used to ground abstract philosophical claims in concrete moral situations.

Key academic technique demonstrated

The paper demonstrates comparative philosophical analysis: rather than summarizing Ross in isolation, it evaluates his theory against utilitarian and Kantian alternatives, showing where each framework succeeds or fails on explanatory grounds. This technique is especially effective in ethics essays, as it forces the writer to articulate not just what a theorist believes, but why that position is preferable to rival views.

Structure breakdown

The essay opens by introducing Ross's core rejection of monistic ethical theories. It then examines the content of his conditional duties and compares them favorably to utilitarianism. The second half shifts to a more critical reading, identifying where Ross's own theory becomes consequence-sensitive and exploring the terminological difficulties he admits around the phrase "prima facie duty." The conclusion returns to the broader significance of the concept for modern ethics.

Introduction to Ross's Ethical Framework

In his essay "What Makes Right Acts Right?" W.D. Ross rejects both Mill's utilitarianism and Kant's deontology, asserting that ethics cannot be reduced to any single good, as claimed by these theories. Instead, he argues that moral acts are those that generate the greatest good, where "good" can imply many diverse things, including pleasures and duties. He begins by assessing what individuals take into consideration while deliberating about which action to take.

When an individual reflects on a promise he or she has made, Ross observes that the individual normally does not consider it with regard to its consequences. Furthermore, keeping the promise is not thought of as good merely because it results in the best outcomes. Under ordinary circumstances, the word "promise" itself suffices to demand that the promise be kept; however, this obligation can be annulled if breaking the promise does more substantial good.

Ross contends that, instead of any one simple principle governing how one must act, there are numerous ethically relevant facts — such as one's will, relationships, and consequences — that create a conditional, or prima facie, duty. Therefore, in the absence of any significant countervailing concern, an individual has a conditional duty to abide by promises, be truthful, be kind to friends, and so on. To ascertain whether one has an actual (or proper) duty, one must consider all the morally relevant particulars of one's situation.

Critique of Utilitarianism and Kantian Deontology130 words
Ross developed a number of conditional duties — duties arising from promises, from prior relationships, from outcomes, from one's past wrongdoings, and others — in order to compare his approach with utilitarianism. While utilitarianism is an essentially simple theory, he believes it does…
Prima Facie Duties and Conditional Obligation110 words
Ross's essay arrives at the concept of prima facie (conditional) duty, an idea that some modern authors have deemed worthy of integration with a revised version of certain aspects of Kantian deontology. Ross disagrees with utilitarian ethics' commitment to treating the maximization of…
Consequence-Sensitivity and the Limits of Promise-Keeping160 words
While Ross appears to offer a direct and simple opposition to utilitarianism, he reluctantly accepts a point of utilitarian theory, acknowledging that circumstances may arise wherein fulfilling a vow may have extremely adverse consequences, and the right thing would be to break the promise (Banham, 2010). Therefore, while a promise can be kept for reasons unrelated to…
Cases of Conscience and Terminology120 words
Ross introduces the prima facie concept as a means to express consequence-sensitivity, which results in cases where two moral obligations clash and both cannot be adopted simultaneously. The author terms these "cases of conscience." Ross's terminology is, by…
