Obligation incompatibilism is the view that determinism precludes moral obligation. I argue for the following. Two principles, ‘ought’ implies ‘can’ and ‘ought not’ is equivalent to ‘impermissi...

As Socrates famously noted, there is no more important question than how we ought to live. The answer to this question depends on how the reasons that we have for living in various different ways combine and compete. To illustrate, suppose that I've just received a substantial raise. What should I do with the extra money? I have most moral reason to donate it to effective charities but most self-interested reason to spend it on luxuries for myself. So, whether I (...) should live my life as I have most moral reason to live it or as I have most self-interested reason to live it depends on how these and other sorts of reasons combine and compete to determine what I have most reason to do, all things considered. This Element seeks to figure out how different sorts of reasons combine and compete to determine how we ought to live. (shrink)

A woman risks her life to save someone else's child from a house that is on fire. While in his prime, a man donates one of his kidneys to a dialysis patient whom he does not know. In Auschwitz, Maximilian Kolbe sacrifices his life for the life of another prisoner.

Expressivists, such as Blackburn, analyse sentences such as 'S thinks that it ought to be the case that p' as S hoorays that p'. A problem is that the former sentence can be negated in three different ways, but the latter in only two. The distinction between refusing to accept a moral judgement and accepting its negation therefore cannot be accounted for. This is shown to undermine Blackburn's solution to the Frege-Geach problem.

Discussions of supererogation usually focus on cases in which the agent can choose among a finite number of options. However, Daniel Muñoz has recently shown that cases in which the agent faces an infinite chain of increasingly less good options make trouble for existing definitions of supererogation. Muñoz proposes a promising new definition as a solution to the problem of infinite cases. I argue that any acceptable account of supererogation must (1) enable us to accurately identify supererogatory acts in both (...) finite and infinite option cases. It must also (2) include a suitably related account of what makes one act more supererogatory than another for finite, infinite, single-choice (one agent choosing among several supererogatory options) and inter-choice (two different agents, each choosing a supererogatory option) cases. I further argue that the best current account of supererogation for finite cases works well for finite cases, but cannot handle infinite cases. However, Muñoz’s proposal cannot handle inter-choice cases in either finite or infinite cases. I conclude we still need an account for infinite cases, and may have to settle for separate definitions of supererogation for finite and infinite cases. (shrink)

According to many, to have epistemic justification to believe P is just for it to be epistemically permissible to believe P. Others think it is for believing P to be epistemically good. Yet others think it has to do with being epistemically blameless in believing P. All such views of justification encounter problems. Here, a new view of justification is proposed according to which justification is a kind of composite normative status. The result is a view of justification that offers (...) hope of solving some longstanding epistemological problems. (shrink)

Recently, a number of philosophers have argued that we can and should “consequentialize” non-consequentialist moral theories, putting them into a consequentialist framework. I argue that these philosophers, usually treated as a group, in fact offer three separate arguments, two of which are incompatible. I show that none represent significant threats to a committed non-consequentialist, and that the literature has suffered due to a failure to distinguish these arguments. I conclude by showing that the failure of the consequentializers’ arguments has implications (...) for disciplines, such as economics, logic, decision theory, and linguistics, which sometimes use a consequentialist structure to represent non-consequentialist ethical theories.

Promises to perform supererogatory actions present an interesting puzzle. On the one hand, this seems like a promise that one should be able to keep simply by performing some good deed or other. On the other hand, the only way to keep it is to do something that exceeds one’s duties. But any good deed that one performs, which might otherwise have been supererogatory, will not go above and beyond what one is morally required to do in such a case (...) because one has an obligation that one does not normally have—namely, an obligation to do something supererogatory. Thus, some scholars have argued that promises of this sort cannot possibly be kept and so are wrong to make. I show that, far from being impossible, keeping promises to supererogate is easy, and so there is nothing wrong with making promises of this sort. (shrink)

Supererogatory acts are those that lie “beyond the call of duty.” There are two standard ways to define this idea more precisely. Although the definitions are often seen as equivalent, I argue that they can diverge when options are infinite, or when there are cycles of better options; moreover, each definition is acceptable in only one case. I consider two ways out of this dilemma.

Whereas geometrical oppositions (logical squares and hexagons) have been so far investigated in many fields of modal logic (both abstract and applied), the oppositional geometrical side of “deontic logic” (the logic of “obligatory”, “forbidden”, “permitted”, . . .) has rather been neglected. Besides the classical “deontic square” (the deontic counterpart of Aristotle’s “logical square”), some interesting attempts have nevertheless been made to deepen the geometrical investigation of the deontic oppositions: Kalinowski (La logique des normes, PUF, Paris, 1972) has proposed a (...) “deontic hexagon” as being the geometrical representation of standard deontic logic, whereas Joerden (jointly with Hruschka, in Archiv für Rechtsund Sozialphilosophie 73:1, 1987), McNamara (Mind 105:419, 1996) and Wessels (Die gute Samariterin. Zur Struktur der Supererogation, Walter de Gruyter, Berlin, 2002) have proposed some new “deontic polygons” for dealing with conservative extensions of standard deontic logic internalising the concept of “supererogation”. Since 2004 a new formal science of the geometrical oppositions inside logic has appeared, that is “ n -opposition theory”, or “NOT”, which relies on the notion of “logical bi-simplex of dimension m ” ( m = n − 1). This theory has received a complete mathematical foundation in 2008, and since then several extensions. In this paper, by using it, we show that in standard deontic logic there are in fact many more oppositional deontic figures than Kalinowski’s unique “hexagon of norms” (more ones, and more complex ones, geometrically speaking: “deontic squares”, “deontic hexagons”, “deontic cubes”, . . ., “deontic tetraicosahedra”, . . .): the real geometry of the oppositions between deontic modalities is composed by the aforementioned structures (squares, hexagons, cubes, . . ., tetraicosahedra and hyper-tetraicosahedra), whose complete mathematical closure happens in fact to be a “deontic 5-dimensional hyper-tetraicosahedron” (an oppositional very regular solid).

Continuing prior work by the author, a simple classical system for personal obligation is integrated with a fairly rich system for aretaic (agent-evaluative) appraisal. I then explore various relationships between definable aretaic statuses such as praiseworthiness and blameworthiness and deontic statuses such as obligatoriness and impermissibility. I focus on partitions of the normative statuses generated ("normative positions" but without explicit representation of agency). In addition to being able to model and explore fundamental questions in ethical theory about the connection between (...) blame, praise, permissibility and obligation, this allows me to carefully represent schemes for supererogation and kin. These controversial concepts have provided challenges to both ethical theory and deontic logic, and are among deontic logic's test cases. (shrink)

On the traditional deontic framework, what is required (what morality demands) and what is optimal (what morality recommends) can't be distinguished and hence they can't both be represented. Although the morally optional can be represented, the supererogatory (exceeding morality's demands), one of its proper subclasses, cannot be. The morally indifferent, another proper subclass of the optional-one obviously disjoint from the supererogatory-is also not representable. Ditto for the permissibly suboptimal and the morally significant. Finally, the minimum that morality allows finds no (...) place in the traditional scheme. With a focus on the question, What would constitute a hospitable logical neighborhood for the concept of supererogation?, I present and motivate an enriched logical and semantic framework for representing all these concepts of common sense morality.

ZusammenfassungDem sogenannten Knobe-Effekt zufolge bestimmt die moralische Valenz von Nebeneffekten menschlichen Verhaltens die Zuschreibung ihrer absichtlichen Verursachung. Wir argumentieren, dass erstens die empirisch ermittelten sozialpsychologischen Daten den Knobe-Effekt in der üblichen Lesart nicht belegen, vor allem wegen der unvollständigen Untersuchung der entscheidenden moralischen Varianzfaktoren. Zweitens zeigen wir, dass - und wie - eine spezifische Version des traditionellen Prinzips des Doppeleffekts den empirisch bestätigten Teil des Knobe-Effekts philosophisch erklärt. Die Erklärungskraft des Prinzips des Doppeleffekts kann auch als eine Rechtfertigung eben dieses (...) Prinzips gesehen werden. (shrink)

In Manipulated Agents: A Window to Moral Responsibility, Alfred Mele invokes radical reversal cases in which one agent is covertly manipulated to be just like another agent in relevant respects to defend a version of the following “externalist” thesis: how agents acquire their springs of action, such as desires and beliefs, bears on whether they are morally responsible for their actions. I assess proposed rationales for the crucial verdict that agents in such cases are not responsible for their germane actions. (...) I argue for the superiority of Mele’s rationale and propose that these cases also support accepting an externalist constraint on other normative appraisals, such as those of practical rationality. Key words: Moral obligation; practical rationality; radical reversal cases; ultimate origination; zygote argument. (shrink)

I start by using “Frankfurt-type” examples to cast preliminary doubt on the “Objective View” - that one is blameworthy for an action only if that action is objectively wrong, and follow by providing further arguments against this view. Then I sketch a replacement for the Objective View whose core is that one is to blame for performing an action, A, only if one has the belief that it is morally wrong for one to do A, and this belief plays an (...) appropriate role in the etiology of one's A-ing. I next defend this core against recently advanced objections and then show how it helps with defusing a skeptical challenge from the direction of causal determinism against blameworthiness. Finally, I exploit the core to isolate an analogous epistemic core for nonmoral but “normative” varieties of blameworthiness. (shrink)

Frankfurt examples attempt to establish that a person can be morally responsible, morally blameworthy, for instance, for doing something despite not being able to do otherwise, as long as the conditions that render him unable to do otherwise play no role in bringing about what he does.Harry Frankfurt, “Alternate Possibilities and Moral Responsibility,” The Journal of Philosophy, Vol. 66 . A more cautious manner of arguing would be to assume only that it is not demonstrated that the agent is not (...) morally responsible. See, e.g., John M. Fischer, “Recent Work on Moral Responsibility,” Ethics, Vol. 110 ; Ishtiyaque Haji and Michael McKenna, “Defending Frankfurt’s Argument in Deterministic Contexts: A Reply to Palmer,” The Journal of Philosophy, Vol. 103 ; and Ishtiyaque Haji and Michael McKenna, “Dialectical Delicacies in the Debate about Freedom and Alternative Possibilities,” The Journal of Philosophy, Vol. 101 .

In a recent and highly engaging paper, Reid Blackman argues against the principle that if determinism is true, then it is not the case that one can do otherwise. He says that the combination of determinism, CAN, and plausible principles, such as the ‘ought’ implies ‘can’ principle, entails false conclusions about the normative, including the propositions that people never fail to do what they ought to have done and one never has any reason to do anything but what one does. (...) If CAN is, indeed, false compatibilists ought to be motivated to defend a reading of ‘can’ such that one can do otherwise even if determinism is true. In this paper I argue against Blackman’s dismissal of CAN on the basis that his relevant arguments are insufficiently sensitive to strong and weak readings of ‘can.’. (shrink)

Frankfurt examples invite controversy over whether the pertinent agent in these examples lacks the specific ability to do otherwise, and whether what she does can be obligatory or permissible. We develop an account of ability that implies that this agent does not have the specific ability to refrain from performing the germane action. The account also undergirds a view of obligation that entails that it is morally required or prohibited for an agent to perform an action only if she has (...) the specific ability to do, and to do otherwise than, perform it. Therefore, in Frankfurt examples, it is neither obligatory nor impermissible for the relevant agent to do what she does. (shrink)

The set with the following members is inconsistent: F-Lesson: A person can be blameworthy for performing an action even though she cannot refrain from performing it. Equivalence: ‘Ought not’ is equivalent to ‘impermissible.’ OIC: ‘Ought’ implies ‘can’ and ‘ought not’ implies ‘can refrain from.’ BRI: Necessarily, one is morally blameworthy for doing something only if it is overall morally impermissible for one to do it. Since Equivalence seems unassailable, one can escape the inconsistency by renouncing any one of the other (...) members. I first argue against BRI and then motivate a replacement for it that ties blameworthiness to belief in impermissibility. (shrink)

Ever since its formulation by Hume, the idea of an inferential barrier between non-ethical (“is”) propositions and ethical (“ought”) propositions (also known as Hume’s is-ought thesis) has received much philosophical attention. Prior’s Paradox appears to demonstrate that the ban on “is”-“ought” inferences is violated in every possible instance, from which it follows that Hume’s is-ought thesis must be false. In this article, I will formulate a logically rigorous version of Hume’s is-ought thesis, introduce Prior-style counterexamples, and suggest how they might (...) demonstrate the falsity of Hume’s is-ought thesis, identify the substitution criterion, and develop at length the unrestricted and restricted versions of this criterion as it is applied by Pigden and Schurz. Thereafter, I will outline Schurz’s defence of the is-ought gap in accordance with his interpretation of the substitution criterion, before introducing a more sophisticated version of Prior-style objections, proposing a possible response from Pigden, identifying the costs of Pigden’s response and counter proposing a response on behalf of Schurz through an extension of his approach, and offering concluding remarks.

The crucial feature of obligation sentences to which the puzzles point is that such sentences, and evaluative sentences more generally, are defeasible. They may be warranted, given some information, only to be defeated by further information. A theory that recognizes this no longer needs to see conditional obligation as anything more than a simple combination of unary obligation and the conditional.

A familiar part of debates about supererogatory actions concerns the role that cost should play. Two camps have emerged: one claiming that extreme cost is a necessary condition for when an action is supererogatory, while the other denies that it should be part of our definition of supererogation. In this paper, I propose an alternative position. I argue that it is comparative cost that is central to the supererogatory and that it is needed to explain a feature that all accounts (...) agree is central to the very notion of supererogation: optionality. Perhaps because of this agreement on its importance, few attempts have been made to clarify and explain the notion of optionality. I argue that giving an account of the optionality of supererogatory requires drawing a line between doing the bare minimum permissible and going beyond the bare minimum and that this line ought to be drawn based on comparative cost of alternative permissible acts. Having outlined my account and motivated it, I discuss and reject two concerns that might be raised: firstly, that it is extreme cost, not comparative cost, that matters and, secondly, that in fact no cost is needed for an act to be supererogatory. (shrink)

It is often claimed that all acts of supererogation involve sacrifice. This claim is made because it is thought that it is the level of sacrifice involved that prevents these acts from being morally required. In this paper, I will argue against this claim. I will start by making a distinction between two ways of understanding the claim that all acts of supererogation involve sacrifice. I will then examine some purported counterexamples to the view that supererogation always involves sacrifice and (...) examine their limitations. Next, I will examine how this view might be defended, building on comments by Dale Dorsey and Henry Sidgwick. I will then argue that the view and the argument in favor of it should be rejected. I will finish by showing how an alternative explanation for the limits of moral obligation avoids the problems facing The Sacrifice View. (shrink)

A commonly accepted feature of commonsense morality is that there are some acts that are supererogatory or beyond the call of duty. Recently, philosophers have begun to ask whether something like supererogation might exist in other normative domains such as epistemology and esthetics. In this paper, I will argue that there is good reason to think that sporting supererogation exists. I will then argue that recognizing the existence of sporting supererogation is important because it highlights the value of sport as (...) a mutual pursuit of excellence and reinforces the value of sportsmanship. (shrink)

It is a recognizable feature of commonsense morality that some actions are beyond the call of duty or supererogatory. Acts of supererogation raise a number of interesting philosophical questions and debates. This article will provide an overview of three of these debates. First, I will provide an overview of the debate about whether or not acts of supererogation exist. Next, I will investigate the issue of how to define the supererogatory. I will finish by examining a problem known as the (...) Paradox of Supererogation. (shrink)

How can we make sense of God’s moral goodness if God cannot be subject to moral obligations? This question is troubling for divine command theorists, as if we cannot make sense of God’s moral goodness then it seems hard to see how God’s commands could be morally good. Alston argues that the concept of supererogation solves this problem. If we accept the existence of acts that are morally good but not morally required then we should accept that there is no (...) need for an act to fulfill a moral obligation in order for it to be morally good. This view has been criticized by both Stump and Lombardi :313–326, 2005), who claim that it is impossible for an agent who has no obligations to perform acts of supererogation. Young attempts to defend Alston’s solution by offering a new analysis of supererogation. In this paper I will argue first that Young fails to provide an adequate response to Lombardi’s objection. I will then provide my own defence of Alston’s proposal. (shrink)

It is commonly assumed that praiseworthiness should form part of the analysis of supererogation. I will argue that this view should be rejected. I will start by arguing that, at least on some views of the connection between moral value and praiseworthiness, it does not follow from the fact that acts of supererogation go beyond what is required by duty that they will always be praiseworthy to perform. I will then consider and dismiss what I will call the Argument from (...) Stipulation in favour of holding that acts of supererogation are always praiseworthy. Next, I will examine what I will call the Necessary Connection Argument, which posits a necessary connection between supererogation and praiseworthiness. I will argue that the intuitions used to motivate this argument are best explained by a debunking explanation. (shrink)

Standing in San Marco Cathedral in Venice, you immediately notice the exquisitely decorated spandrels: the triangular spaces bounded on either side by adjoining arches and by the dome above. You would be forgiven for seeing them as the starting point from which to understand the surrounding architecture. To do so would, however, be a mistake. It is a similar mistaken inference that evolutionary biologists have been accused of making in assuming a special adaptive purpose for such biological features as fingerprints (...) and chins. I argue that a mistake of just this sort is being made by ethicists who appeal to the intrinsic value of supererogatory acts in their efforts to make space for supererogation in ethical theory. Many cases of supererogatory action are simply spandrels: by-products of uncontroversial commitments elsewhere in our moral thought. This is not to downplay their value but rather to show that their value need not be the justification for making room for the supererogatory. I demonstrate this by examining two areas: rights and the distribution of burdens among a group. My argument has significance for those who take themselves to be defends of the possibility of supererogatory actions, as well as those who are committed to the contrary and those who believe themselves to be indifferent on the matter.

A general introduction to consequentialism.

This article proposes a general strategy to overcome normative conflicts, namely, paradoxes represented in Standard Deontic Logic. This solution is based on preference relations between norms that circumvent situations of conflict. Pragmatic justifications of the proposed method are also given.

Overview of fundamental work in deontic logic.

The principle of alternate possibilities says that you are morally praiseworthy or blameworthy for something you do only if you could have done otherwise. Frankfurt examples are putative counterexamples to PAP. These examples feature a failsafe mechanism that ensures that some agent cannot refrain from doing what she does without intervening in how she conducts herself, thereby supposedly sustaining the upshot that she is responsible for her behavior despite not being able to do otherwise. I introduce a Frankfurt example in (...) which the agent who could not have done otherwise is God. Paying attention to the freedom requirements of moral obligation, the example is commissioned, first, to assess whether various statesof affairs that are unavoidable for God can be obligatory for God and for whichGod can be praiseworthy. The example is, next, used to unearth problems with conventional Frankfurt examples that feature human agents. I argue that conceptual connections between responsibility and obligation cast suspicion on these examples. Pertinent lessons that the divine Frankfurt example helps to reveal motivate the view that divine foreknowledge and determinism, assuming that both preclude freedom to do otherwise, may well imperil obligation and responsibility. (shrink)

In this paper we offer an argument against supererogation and in favour of moral perfectionism. We argue three primary points: 1) That the putative moral category is not generated by any of the main normative ethical systems, and it is difficult to find space for it in these systems at all; 2) That the primary support for supererogation is based on intuitions, which can be undercut by various other pieces of evidence; and 3) That there are better reasons to favour (...) perfectionism, including competing intuitions about the good-ought tie-up, and the epistemic preference for theoretical simplicity.

There is a growing consensus, long maintained by Derek Parfit, that there is an important distinction between what we have reason to do on the one hand, and what it is rational for us to do on the other. Philosophers are now realising that there is a conceptual distinction between rationality and normativity. Given this distinction, it thus becomes a substantive question whether rationality is genuinely normative; that is, whether there is any reason to do what rationality requires. While some (...) philosophers have argued that we sometimes have reason to do what rationality requires, it is notoriously difficult to show that there are always universal and categorical reasons to do what rationality requires. But if it is not the case that there are always universal and categorical reasons to do what rationality requires, then rationality is not genuinely normative.This dissertation offers a vindication of the normativity of rationality. I maintain that there is a robust relation between rational requirements and normative reasons. In arguing for this claim, I develop what I call the reasons-sensitive view of rationality, according to which rational requirements are normative verdicts: they are second-order claims about what there is conclusive reason of rationality to do. This view explains why there are always universal and categorical reasons to be rational. So while we may not always have most reason to do what it is rational for us to do, there is always some reason—reasons of rationality—to do what it is rational for us to do. I then show how this reasons-sensitive view addresses and responds to what I diagnose to be the major sources of skepticism about the normativity of rationality. (shrink)
