Perception is said to have assertoric force: It inclines the perceiver to believe its content. In contrast, perceptual imagination is commonly taken to be non-assertoric: Imagining winning a piano contest does not incline the imaginer to believe they actually won. However, abundant evidence from clinical and experimental psychology shows that imagination influences attitudes and behavior in ways similar to perceptual experiences. To account for these phenomena, I propose that perceptual imaginings have implicit assertoric force and put forth a theory—the (...) class='Hi'>Prima Facie View—as a unified explanation for the empirical findings reviewed. According to this view, mental images are treated as percepts in operations involving associative memory. Finally, I address alternative explanations that could account for the reviewed empirical evidence—such as a Spinozian model of belief formation or Gendler’s notion of alief—as well as potential objections to the Prima Facie View.

There are many uses in English of the word “ought” (see Ought). This essay concerns the normative uses and the concepts or properties denoted thereby. In particular, it concerns two nonfinal oughts commonly used in the philosophical literature: prima facie oughts and pro tanto oughts.

This paper presents a nonmonotonic deontic logic based on commonsense entailment. It establishes criteria a successful account of obligation should satisfy, and develops a theory that satisfies them. The theory includes two conditional notions of prima facie obligation. One is constitutive; the other is epistemic, and follows nonmonotonically from the constitutive notion. The paper defines unconditional notions of prima facie obligation in terms of the conditional notions.

Until recently, it was widely assumed in societies with long-established, publicly funded school systems that school attendance served the interests of children, society, and parents alike. In the United States and other common-law jurisdictions, safeguarding and promoting the independent welfare and developmental interests of every child was a public responsibility under the parens patriae doctrine. Compulsory schooling laws enacted under parens patriae authority required all persons having care and control of a child to share their custodial authority with publicly certified (...) teachers for limited periods of time. By compelling all parents to send their children to school, the state ensured that all children had access to instruction and opportunities for social, economic, and civic participation beyond what their parents alone could provide. Parents were incidentally freer to manage the competing demands of domestic life and paid employment, and the enforcement of child labor laws was greatly facilitated by efforts to ensure school attendance. While compulsory schooling laws imposed obvious limits on the custodial authority of all parents for the sake of all children, they were rarely challenged on that basis. Not so today. (shrink)

Sir David Ross introduced prima facie duties, or acts with a tendency to be duties proper. He also spoke of general prima facie principles, wwhich attribute to acts having some feature the tendency to be a duty proper. Like Utilitarians from Mill to Hare, he saw a role for such principles in the epistemology of duty: in the process by means of which, in any given situation, a moral code can help us to find out what (...) we ought to do.After formalizing general prima facie principles as universally quantified conditionals I will show how seeming duties can be detached from them. There will be examples involving lies, burnt offerings and the question of whether to have a napkin on your lap while eating asparagus. They will illustrate the defeasibility of this detachment, how it can lead into dilemmas, and how general prima facie principles are overridden by more specific ones. (shrink)

Analyses are given of the concepts of absolute and prima facie obligation. The former is a maximizing analysis: roughly, one ought absolutely to perform those actions which are performed in the best worlds accessible to one. The latter analysis is roughly this: one ought prima facie to perform those actions which are such that those accessible worlds in which they are performed are better than the closest accessible worlds in which they are not performed. Accounts of (...) conditional obligation, both absolute and prima facie, are also given, and the issue of the detachment of unconditional from conditional obligation is addressed. (shrink)

Even when a person appears to have consented to another’s interference with her interests, we sometimes treat this apparent consent as ineffective. This may either be because the law does not permit consent to validate the actions concerned, or because the consent is undermined by the presence of additional factors which render it insufficiently autonomous to be effective. In this paper I propose that the project of categorising and systematically analysing the latter set of cases, would be furthered by recognising (...) (1) that prima facie consent is undermined when the prima facie consenter’s autonomy to choose whether or not to consent has been unfairly constrained, and (2) that theoretical and doctrinal clarity can be promoted by analysing the factors that unfairly constrain autonomy in the criminal law using a framework developed in contract law to determine analogous questions arising in relation to assent to a contract.

The pressing problem of prima facie validity must be treated on the basis of a differentiation of types of normative rules. Rules stating principles or purposes are always applied as views determining the decision by weighing (but not by subsumption) so that the problem of prima facie validity does not arise. Neither is there a problem of such a restricted form of validity concerning power‐conferring rules. The author shows that prima facie validity of rules (...) of behaviour must not be treated as a different kind of validity and that the notion of prima facie validity can be explained in a logically satisfactory way on the basis of traditional norm‐logical considerations.

It is argued that a little-Discussed notion of prima facie good (and a related notion of a "basic value experience") can throw light on some of the most vexing problems of value theory, About the meaning of 'good', The naturalistic fallacy, The objectivity of value, The fact-Value distinction and intrinsic value. The notion of prima facie good is formally analogous to w d ross's notion of prima facie duty, But is more general (applying to (...) value generally) and (it is argued) is more useful and less problematic. Views of spinoza, Ross, Moore, Perry and recent value theorists are discussed. (shrink)

In "moral philosophy" richard garner and bernard rosen give a counter-Example against w d ross. We have no prima facie duty to tell a neighbor our love life, Although he might gain knowledge and pleasure. I argue that for ross we could have such a prima facie, Though not an actual, Duty. The lover-Acquaintance relation makes unlikely such an action becoming an actual duty. Also we can conceive of cases in which it might be an actual (...) duty; viz. A case in which the divulger is a psychologist who needs to gain the neighbor's confidence in a group therapy situation. (shrink)

Este artículo examina algunos de los problemas que presenta el tratamiento lógico de las obligaciones prima facie en la obra de Carlos Alchourrón. Por una parte, señalaremos que su sistema para los condicionales derrotables DFT no formaliza adecuadamente la noción intuitiva de condición contribuyente que Alchourrón utiliza para elucidar la de condicional derrotable. Por otra parte, argumentaremos que la noción de deber prima facie de David Ross no queda adecuadamente formalizada en el sistema AD de lógica (...) deóntica que Alchourrón construye como una extensión de DFT. This paper deals with some problems concerning the logical treatment of prima facie obligations in the work of Carlos Alchourrón. On the one hand, we will argue that his DFT system for defeasible conditionals does not adequately formalize the intuitive notion of contributory condition used by Alchourrón to elucidate the notion of defeasible conditional. On the other hand, we will argue that David Ross' notion of prima facie duty is not adequately formalized in Alchourrón' s deontic system AD, an extension of his DFT logic. (shrink)

The paper argues that the idea of prima facie rights implies insurmountable difficulties in connection with the function such rights are said to have in a scheme of justice. G vlastos's version of prima facie rights theories is scrutinized as typical and more advanced than others. The paper shows that natural rights are contextually absolute; they cannot (morally) be overruled in a context of normal political circumstances but may have to be disregarded whenever politics is impossible. (...) Vlastos's insight is preserved without sacrificing the integrity of a scheme of justice based on natural rights. (shrink)

In this note it is argued that professor jaakko hintikka's explication of the notion of a 'prima facie obligation' within the framework of deontic logic must be regarded as unsatisfactory. since our world is not morally (or 'deontically') perfect, hintikka's proposal seems to have the absurd consequence that everything is a prima facie obligation.

In The Right and the Good, W. D. Ross commits himself to the view that, in addition to being distinct and defeasible, some prima facie duties are more binding than others. David McNaughton has argued that there appears to be no way of making sense of this claim that is both coherent and consistent with Ross's overall picture. I offer an alternative way of understanding Ross's remarks about the comparative stringency of prima facie duties, which, in (...) addition to being compatible with his view as presented in the text, provides us with a coherent, and indeed plausible, account of what it means for some duties to be more binding than others.

Some conservation biologists invoke the concept of ‘genetic integrity,’ which they generally assume is a good worth preserving without explicit justification. We examine the question of whether or not there is a prima facie duty to preserve genetic integrity in conservation biology. We examine several possible justifications for the potential duty found in the conservation biology literature. We argue, contra a dominant trend of thought in conservation biology, that there is no prima facie duty to preserve (...) genetic integrity and that any moral obligation to preserve genetic integrity in specific cases is merely derivative of other possible duties.

Hobbes advocates 'thin absolutism'; a system of authority that merely ensures respect of the core concepts of sovereignty – hierarchy and normative closure. This new interpretation of Hobbes's absolutism shows that the concerns regarding sovereign tyranny are not fatal to his account of political authority. With thin absolutism, the sovereign is neither necessarily ineffective nor inherently dangerous. This, then, leaves Hobbesian absolutism in the position of being a 'reasonable contender'– a system of political authority that might require our allegiance, but (...) at the very least requires serious attention.

W. K. Clifford famously argued that it is “wrong always, everywhere and for anyone, to believe anything upon insufficient evidence.” Though the spirit of this claim resonates with me, the letter does not. To wit, I am inclined to think that it is not morally wrong for, say, an elderly woman on her death bed to believe privately that she is going to heaven even if she does so on insufficient evidence—indeed, and lest there be any confusion, even if the (...) woman herself deems the evidence for her so believing to be insufficient. After all, her believing so does not appear to endanger, harm, or violate the rights of anyone, nor does it make the world a worse place in a significant, if any, way. That Clifford might have put too fine a point on the matter, however, does not entail that there are no conditions under which it is wrong to believe something upon insufficient evidence. In this paper, I argue that, in cases where believing a proposition (read: believing a proposition to be true) will affect others, it is prima facie wrong to have propositional faith—for present purposes, to believe the proposition despite deeming the evidence for one’s believing to be insufficient—before one has attempted to believe the proposition by proportioning one’s belief to the evidence.

A properly programmed artificially intelligent agent may eventually have one duty, the duty to satisfice expected welfare. We explain this claim and defend it against objections.

Ross divides prima facie duties into derivative and foundational ones, but seems to understand the notion of a derivative prima facie duty in two very different ways. Sometimes he understands them in a non-eliminativist way. According to this understanding, basic prima facie duties ground distinct derivative ones. According to the eliminativist understanding, basic duties do not ground distinct derivative duties, but replace them. On the eliminativist view, discovering that a prima facie duty (...) is derivative is discovering that it is not genuine. The genuine one is the basic one. I argue that Ross is best understood as an eliminativist. (shrink)

THE PROJECT OF THIS PAPER IS TO GIVE AN EXPLICIT DEFINITION OF 'PRIMA FACIE' DUTY EMPLOYING THE NOTION OF DUTY (SIMPLICITER) AS THE ONLY MORAL NOTION. THIS DEFINITION AVOIDS THE CIRCULARITY OF SOME DEFINITIONS WHILE ALSO BEING SUFFICIENTLY GENERAL SO AS NOT TO DEPEND ON THE ADOPTION OF ANY PARTICULAR MORAL VIEWPOINT. THIS PAPER ATTACKS THE VIEW THAT A MORAL PHILOSOPHER (OR AN ANTHROPOLOGIST DESCRIBING A MORAL CODE) CAN ALWAYS IN PRINCIPLE AVOID EMPLOYING THE NOTION OF A ' (...) class='Hi'>PRIMA FACIE' DUTY SIMPLY BY GIVING A CAREFUL STATEMENT OF EACH RULE MAKING EXPLICIT ITS EXCEPTIONS.

In modern German ‘Anschauung’ is translated as intuition. But in Kant’s technical philosophical context, it means an intuition derived from previous visualizations of physical processes in the world of perceptions. The nineteenth century chemists’ predilection for Kantian Anschauung led them to develop an intuitive representation of what exists beyond the bounds of the senses. Molecular structure is one of the illuminating outcomes. (Ochiai 2021, pp. 1–51) This mental habit seems to be dominant among chemists even in the twentieth century, as (...) is illustrated by the electronic theory of organic chemistry and the frontier orbital theory as well. The former assumes that (1) bonds are paired electrons shared by bonded atoms—in fact, electrons in molecules are not localized in bonds; (2) the difference of electronegativities between bonded atoms causes electron drifts—expressed by the curly arrow—that result in bond formation or bond cleavage. The latter focuses on the orbitals that make the greatest contribution to the energy of a system undergoing electron delocalization, while the LCAO method says, as is suggested by the word Linear Combination of Atomic Orbitals, molecular orbitals should be constructed from all of the atomic orbitals that have the appropriate symmetry. In other words, every molecular orbital contributes to some extent to the electronic state of a molecule. The curly arrow in the electronic theory and the orbital lobe in the frontier orbital theory illustrate an intuitive character of these theories. Although both theories rely on such simple and qualitative models rather than mathematically rigid quantum mechanical calculations, they are successful in explaining, predicting, and designing chemical reactions. What makes these prima facie intuitive theories so successful? In this study we address this problem from a historical and philosophical as well as scientific point of view. The key to solve this problem is that they are concerned with only bond formation or bond cleavage, in which the localized-bond principle holds. (shrink)

This paper is about certain of the ways in which rights and liberties are interrelated. It is also about the distinction between "prima facie" and "on balance" rights. Although philosophers concerned with the former issue commonly reject the notion of a prima facie right or ignore it entirely, I argue that an adequate account of how rights are related to liberties must rest on the idea that some rights are only prima facie.

In the early 1980’s van Inwagen presented the Direct Argument for the incompatibility of determinism with moral responsibility. In the course of the ensuing debate, Fischer, McKenna and Loewenstein have replied, each in their own way, that versions of the Direct Argument do not pose even a prima facie threat to compatibilism. Their grounds were that versions of the Direct Argument all use the “Transfer NR” inference rule in a dialectically problematic way. I rebut these replies here. By (...) so doing, I hope to set the Direct Argument debate on a more fruitful path. (shrink)

Raanan Gillon is a noted defender of the four principles approach to healthcare ethics. His general position has always been that these principles are to be considered to be both universal and prima facie in nature. In recent work, however, he has made two claims that seem to present difficulties for this view. His first claim is that one of these four principles, respect for autonomy, has a special position in relation to the others: he holds that it (...) is first among equals. We argue that this claim makes little sense if the principles are to retain their prima facie nature. His second claim is that cultural variation can play an independent normative role in the construction of our moral judgments. This, he argues, enables us to occupy a middle ground between what he sees as the twin pitfalls of moral relativism and moral imperialism. We argue that there is no such middle ground, and while Gillon ultimately seems committed to relativism, it is some form of moral imperialism that will provide the only satisfactory construal of the four principles as prima facie universal moral principles.

Sir David Ross introduced and discussed his notion of prima facie duties in chapter 2 of The Right and the Good , and it is to this chapter that I shall devote most attention. I wish to show that the distinction between prima facie and “actual” duties, as expounded by Ross, entails that there are no “actual” duties; and I wish to show that this unfortunate consequence of the distinction arises from Ross's explicit epist-emological views. Writers (...) such as Ewing, Baier and Frankena, who have quoted Ross's distinction with some degree of approval, force one to ask how, precisely, they interpreted it. In the first part of this paper I set out Ross's exposition in detail, since failure to do this has blinded adherents to its difficulties; in the second part I summarise my findings and indicate the problems Ross rightly poses for us; in the third part I suggest possible sources for Ross's views. Two points should be noted at the outset. Firstly, the distinction applies to acts, not actions; “act” refers to “the thing done, the initiation of change, and ‘action’ the doing of it, the initiating of change, from a certain motive” . Secondly, the term “right” is used throughout as synonymous with “what is my duty”. (shrink)
