RECENT STUDIES IN NORMATIVE ETHICS have concentrated on act evaluations, neglecting, almost ignoring, agent evaluations. A partial explanation of this defect is found in two related ones: the neglect of act evaluations other than the obligation notions, and the failure to do justice even to them. In each case, neglecting the "other" concepts is implicated in serious misunderstandings of what is considered—or more accurately, what is over-considered. Take, for example, the view that it is obligatory to obtain for oneself (...) the greatest good one can, e.g., pleasure. Even a cursory study of prudence and other primarily self-regarding notions could have saved Moore, Ross, Ewing, and many others from holding or committing themselves to this silly view. (shrink)

Agentive awareness is the awareness one has of oneself as acting, or as performing a particular action. Theorists distinguish between high-level (e.g., Wegner 2002), low-level (e.g., Frith 2007), and integrative approaches (e.g., Pacherie 2008) to explaining this brand of subjective awareness. In this paper, I evaluate the commitment of both low-level and integrative approaches to the claim that the representations involved in sensorimotor control, specifically as described by the comparator model (e.g., Frith 1992), contribute in some significant way to agentive (...) awareness. I examine the main empirical data offered in support of this claim and argue that it does not succeed in establishing a role for sensorimotor states in generating agentive awareness. This helps clear the way for high-levelapproaches to explaining this phenomenon. (shrink)

Argument evaluation, one of the central problems in argumentation theory, consists in studying what makes an argument a good one. This paper proposes a formal approach to argument evaluation from the perspective of justification logic. We adopt a multi-agent setting, accepting the intuitive idea that arguments are always evaluated by someone. Two general restrictions are imposed on our analysis: non-deductive arguments are left out and the goal of argument evaluation is fixed: supporting a given proposition. Methodologically, (...) our approach uses several existing tools borrowed from justification logic, awareness logic, doxastic logic and logics for belief dependence. We start by introducing a basic logic for argument evaluation, where a list of argumentative and doxastic notions can be expressed. Later on, we discuss how to capture the mentioned form of argument evaluation by defining a preference operator in the object language. The intuitive picture behind this definition is that, when assessing a couple of arguments, the agent puts them to a test consisting of several criteria. As a result of this process, a preference relation among the evaluated arguments is established by the agent. After showing that this operator suffers a special form of logical omniscience, called preferential omniscience, we discuss how to define an explicit version of it, more suitable to deal with non-ideal agents. The present work exploits the formal notion of awareness in order to model several informal phenomena: awareness of sentences, availability of arguments and communication between agents and external sources. We discuss several extensions of the basic logic and offer completeness and decidability results for all of them. (shrink)

In developing artificial intelligence (AI), researchers often benchmark against human performance as a measure of progress. Is this kind of comparison possible for moral cognition? Given that human moral judgment often hinges on intangible properties like “intention” which may have no natural analog in artificial agents, it may prove difficult to design a “like‐for‐like” comparison between the moral behavior of artificial and human agents. What would a measure of moral behavior for both humans and AI look like? We unravel the (...) complexity of this question by discussing examples within reinforcement learning and generative AI, and we examine how the puzzle of evaluating artificial agents' moral cognition remains open for further investigation within cognitive science.

In this chapter I discuss Taylor’s claim that strong evaluation is inevitable for human agency: without a framework of strong evaluations human agents would be in a crisis which Taylor calls, perhaps misleadingly, “an identity crisis”. With a broad brush I introduce some of the essential background in first three sections, and scrutinize the inevitability of strong evaluation more closely in the last three sections. I introduce first the distinction between the engaged perspective, which in Taylor’s view provides (...) the correct approach to humans and values, and two kinds of disengaged perspectives (objectivist and subjectivist ones) (2.1). Taylor’s ideal typical distinction (engaged and disengaged) resembles Sellars’s (1963) distinction between manifest and scientific image, but Taylor takes the scientific worldview to be only one objectivist variant of disengaged views: the Cartesian view of mind is detached from the lifeworldly reality, and is a variant of a subjectivist disengaged view. There are many aspects to Taylor’s philosophical anthropology, based on such an engaged perspective. He defends many “human constants” related to humans as social, self-interpreting, embodied language animals. Although here the focus is merely on one of the human constants, namely on the claim that humans are essentially strong evaluators, I give a sketchy account of the essentials of the broader picture in section 2.2. Taylor uses transcendental argumentation in trying to show the inescapability of strong evaluation in human life. I will, following Nicholas Smith’s reconstruction, discuss Taylor’s reasons for adopting such argumentative strategy in relation to this issue, as opposed to socalled ordinary language philosophy, phenomenological description, hermeneutical interpretation, or strict Hegelian dialectics (2.3). The central point is that although we may want to stress the hermeneutical or interpretive nature of being-in-the-world, and the constitutive nature of human self-interpretations, the few human constants are true whether explicitly taken to be true or not: humans are self-interpreting animals, or strong evaluators, even though they may hold opposing theories in their self-interpretations (cf. Abbey 2000, 4). In a sense, Taylor’s label for his claim, which he terms a “transcendental argument”, may seem to make heavy weather of a simple point: without strong evaluation those aspects of life and experience which presuppose strong evaluation would not be possible. These aspects of life include more or less everything that is peculiarly human. The arguments try to bring into focus these dependencies: strong evaluations are inescapable for our lives as humans or as persons, as opposed to “mere” animals. To be fully outside the scope of strong evaluation is to be in a pathological state. Various disengaged theories of humans neglect this. These are theories of human agency, subjectivity, personhood or identity which have ignored this dimension of human life, or have not taken it to be essential. Taylor’s arguments are directed against such views. In this chapter I will clarify the nature of Taylor’s argument by distinguishing different concepts (human agency, personhood, subjectivity, selfhood, and identity) and asking what it is exactly that strong evaluation is necessary for (2.4). The notions of personhood and identity will be discussed in more detail in the next two chapters. The crucial point in Taylor’s argumentation is made by the claim that for someone capable of strong evaluation, the lack of a framework of strong evaluations involves them in a terrible, frightening crisis, an identity-crisis. I will distinguish several meanings of this claim and discuss their validity in 2.5. I suggest that some “identity-crises” are not at all what Taylor has in mind. But the point itself is valid: without a framework of strong evaluations, human agents would be in a state of crisis. In the last section, I defend Taylor’s view against possible counterexamples, posed by Owen Flanagan and Paul Johnston. (shrink)

Experimental philosophers have investigated various ways in which non‐epistemic evaluations can affect knowledge attributions. For example, several teams of researchers (Beebe and Buckwalter 2010; Beebe and Jensen 2012; Schaffer and Knobe 2012; Beebe and Shea 2013; Buckwalter 2014b; Turri 2014) report that the goodness or badness of an agent’s action can affect whether the agent is taken to have certain kinds of knowledge. These findings raise important questions about how patterns of folk knowledge attributions should influence philosophical theorizing (...) about knowledge. (shrink)

ArgumentAgent-based social simulations have historically been evaluated using two criteria: verification and validation. This article questions the adequacy of this dual evaluation scheme. It claims that the scheme does not conform to everyday practices of evaluation, and has, over time, fostered a theory-practice gap in the assessment of social simulations. This gap originates because the dual evaluation scheme, inherited from computer science and software engineering, on one hand, overemphasizes the technical and formal aspects of the implementation process (...) and, on the other hand, misrepresents the connection between the conceptual and the computational model. The mismatch between evaluation theory and practice, it is suggested, might be overcome if practitioners of agent-based social simulation adopt a single criterion evaluation scheme in which: i) the technical/formal issues of the implementation process are tackled as a matter of debugging or instrument calibration, and ii) the epistemological issues surrounding the connection between conceptual and computational models are addressed as a matter of validation.

We document outcome bias in situations where an agent makes risky financial decisions for a principal. In three experiments, we show that the principal’s evaluations and financial rewards for the agent are strongly affected by the random outcome of the risky investment. This happens despite her exact knowledge of the investment strategy, which can, therefore, be assessed independently of the outcome. The principal thus judges the same decision by the agent differently, depending on factors that the (...) class='Hi'>agent has no influence on. The effect of outcomes persists in a setting where principals communicate a preferred investment level. Principals are more satisfied with the agent after a random success when the agent did not follow the requested investment level, than after a failed investment that followed their explicit request.

Traditional studies have shown that the moral judgments are influenced by many biasing factors, like the consequences of a behavior, certain characteristics of the agent who commits the act, or the words chosen to describe the behavior. In the present study we investigated a new factor that could bias the evaluation of morally relevant human behavior: the perceived similarity between the participants and the agent described in the moral scenario. The participants read a story about a driver (...) who illegally overtook another car and hit a pedestrian who was crossing the street. The latter was taken to the hospital with a broken leg. The driver was described either as being similar to the participant (a student, 21 years old, the same gender as th­e participant) or dissimilar (a retired person, 69 years old, different gender as the participant). The results show that the participants from the increased similarity group expressed more lenient evaluations of the immorality of the driver’s behavior compared to the participants from the decreased similarity group. The results are discussed within a framework which puts emphasis on motivational and protective reasons. (shrink)

According to a naïve view sometimes apparent in the writings of moral philosophers, ‘ought’ often expresses a relation between agents and actions – the relation that obtains between an agent and an action when that action is what that agent ought to do. It is not part of this naïve view that ‘ought’ always expresses this relation – on the contrary, adherents of the naïve view are happy to allow that ‘ought’ also has an epistemic sense, on which (...) it means, roughly, that some proposition is likely to be the case, and adherents of the naïve view are also typically happy to allow that ‘ought’ also has an evaluative sense, on which it means, roughly, that were things ideal, some proposition would be the case.1 What is important to the naïve view is not that these other senses of ‘ought’ do not exist, but rather that they are not exhaustive – for what they leave out, is the important deliberative sense of ‘ought’, which is the central subject of moral inquiry about what we ought to do and why – and it is this deliberative sense of ‘ought’ which the naïve view understands to express a relation between agents and actions.2 In contrast, logically and linguistically sophisticated philosophers – with a few notable exceptions3 – have rejected this naïve view. According to a dominant perspective in the interpretation of deontic logic and in linguistic semantics, for example, articulated by Roderick Chisholm (1964) and Bernard Williams (1981) in philosophy and in the dominant paradigm in linguistic semantics as articulated in particular by..

According to a naive view sometimes apparent in the writings of moral philosophers, 'ought' often expresses a relation between agents and actions—the relation that obtains between an agent and an action when that action is what that agent ought to do. It is not part of this naive view that 'ought' always expresses this relation—adherents of the naive view are happy to allow that 'ought' also has an evaluative sense, on which it means, roughly, that were things ideal, (...) some proposition would be the case. What is important to the naive view is that there is also a deliberative sense of 'ought', on which it relates agents to actions. In contrast, logically and linguistically sophisticated philosophers have typically rejected this naive view. According to them, there is no argument-place for an agent in any relation expressed by 'ought', nor is there any argument-place for an action. According to this view, if Jim ought to jam, that is not because there is a special distinctive deliberative ought relation between Jim and jamming; rather, it is because a certain proposition ought to be the case: namely, that Jim jams. This essay defends the naive view, by first arguing that there are two distinct normative senses of 'ought', which actually exhibit different syntactic behavior, and then going on to argue that the deliberative sense of 'ought' relates agents to actions, rather than to propositions. It closes by drawing lessons for a range of issues in moral theory. (shrink)

-/- This essay discusses the relation between ideal theory and two forms of political moralism identified by Bernard Williams, structural and enactment views. It argues that ideal theory, at least in the sense Rawls used that term, only makes sense for structural forms of moralism. These theories see their task as describing the constraints that properly apply to political agents and institutions. As a result, they are primarily concerned with norms that govern action. In contrast, many critiques of ideal theory (...) are structured and motivated by their commitment to an enactment model of political theorizing. This instead sees political agents and institutions as instruments for producing or promoting better states of affairs. Enactment models treat the evaluations that rank different states of affairs as justificatorily basic, rather than norms governing action on which structural models focus. This reveals an important feature of debates about ideal theory. Whether ideal theory is capable of appropriately guiding action will depend on what the criteria for appropriately guiding action are, about which different theorists have importantly different views. For example, some popular strategies for defending ideal theory fail, while it may be much less clear that some alternatives to ideal theory can provide action guidance than their advocates claim.

Evaluative judgements have both belief-like and desire-like features. While cognitivists think that they can easily explain the belief-like features, and have trouble explaining the desire-like features, non-cognitivists think the reverse. I argue that the belief-like features of evaluative judgement are quite complex, and that these complexities crucially affect the way in which an agent's values explain her actions, and hence the desire-like features. While one form of cognitivism can, it turns out that non-cognitivism cannot, accommodate all of these complexities. (...) The upshot is that that form of cognitivism can explain both features of evaluative judgements, and that non-cognitivism can explain neither. (shrink)

Agent-based accounts of virtue ethics, such as the one provided by Michael Slote, base the rightness of action in the motive from which it proceeds. A frequent objection to agent-basing is that it does not allow us to draw the commonsense distinction between doing the right thing and doing it for the right reasons, that is, between act-evaluation and agent-appraisal. I defend agent-basing against this objection, but argue that a more fundamental problem for this account (...) is its apparent failure to provide adequate argue action guidance. I then show that this problem can be solved by supplementing an agent-based criterion of right action with a hypothetical-agent criterion of action guidance. (shrink)

Our beliefs, intentions, desires, regrets, and fears are evaluable for fit—they can succeed or fail to be fitting responses to the objects they are about. Can our headaches and heartrates be evaluable for fit? The common view says ‘no’. This chapter argues: sometimes, yes. First, it claims that when a racing heart accompanies fear it seems to have the typical characteristics of fit-evaluable items. Then, it suggests that suspicion of this initial impression is explained by the assumption that whether an (...) item is ever fit-evaluable is determined by the type of item it is. Fear is the type of thing that can be fit-evaluable, a racing heart is not. The chapter then proposes an alternative whereby the same type of item can be fit-evaluable on one occasion but not on another. What explains the difference, it is argued, is that only in the former occasion the item is explained by the agent’s narrative as an element of a fit-evaluable response. (shrink)

According to agent-based approaches to virtue ethics, the rightness of an action is a function of the motives which prompted that action. If those motives were morally praiseworthy, then the action was right; if they were morally blameworthy, the action was wrong. Many critics find this approach problematically insensitive to an act’s consequences, and claim that agent-basing fails to preserve the intuitive distinction between agent- and act-evaluation. In this article I show how an agent-based account (...) of right action can be made sensitive to an act’s consequences. According to the approach which I defend, an action is right just in case it realizes an agent’s morally praiseworthy motive. Conversely, an action is wrong just in case it realizes a morally blameworthy motive. Specifying act-evaluation in terms of the realization, rather than the expression, of an agent’s motives allows an agent-based approach to distinguish between agent- and act-evaluation. This is because an agent may act from a morally praiseworthy motive, but fail to realize that motive. Her action will therefore not have been the right one, despite its being the expression of morally praiseworthy motives. (shrink)

This paper presents a new solution to the problems for orthodox decision theory posed by the Pasadena game and its relatives. I argue that a key question raised by consideration of these gambles is whether evaluative compositionality (as I term it) is a requirement of rationality: is the value that an ideally rational agent places on a gamble determined by the values that she places on its possible outcomes, together with their mode of composition into the gamble (i.e. the (...) probabilities assigned to them)? The paper first outlines a certain simple response to the Pasadena game and identifies two problems with this response, the second of which is that it leads to a wholesale violation of evaluative compositionality. I then argue that rationality does not require decision makers to factor in outcomes of arbitrarily low probability. A method for making decisions which flows from this basic idea is then developed, and it is shown that this decision method (Truncation) leads to a limited — as opposed to wholesale — violation of evaluative compositionality. The paper then argues that the truncation method yields solutions to the problems posed by the Pasadena game and its relatives that are both attractive in themselves and superior to those yielded by alternative proposals in the literature.

Qualified-agent virtue ethics provides an account of right action in terms of the virtuous agent. It has become one of the most popular, but also most frequently criticized versions of virtue ethics. Many of the objections rest on the mistaken assumption that proponents of qualified-agent virtue ethics share the same view when it comes to fundamental questions about the meaning of the term ‘right action’ and the function of an account of right action. My aim in this (...) paper is not to defend qualified-agent virtue ethics but to correct this misunderstanding, and this will hopefully leave us in a better position to evaluate it. (shrink)

Contemporary philosophers and scientists have done much to expand our understanding of the structure and neural mechanisms of joint action. But the phenomenology of joint action has only recently become a live topic for research.One method of clarifying what is unique about the phenomenology of joint action is by considering the alternative perspective of agents subsumed in group action. By group action we mean instances of individual agents acting while embedded within a group agent, instead of with individual coordination. (...) Paradigm examples are educational bureaucracies, corporations, and nation states. There is a phenomenological difference between agents whose actions are subsumed within a group action as compared to agents who act jointly. Attending to this difference clarifies what is phenomenologically distinctive about joint action.Appealing to an Aristotelian account of agency and to the metaphysical concept of weak emergence, we argue that what makes paradigmatic group action distinctive is the relative inaccessibility, un-revisability, and evaluative simplicity of the group agent’s goal from the perspective of individual agents. This suggests that a distinctive feature of joint agency is the maintenance of a greater sense of individual agency. Put simply, joint agency is often experienced as an enhancement of the individuals’ agency precisely because our paradigmatic agential powers are extended intersubjectively as we act together. In contrast, group agency often involves a loss of the sense of agency, precisely because it is the emergent group agent that maintains the agential powers. (shrink)

This paper reports research concerning a suitable dialogue model for human computer debate. In particular, we consider the adoption of Moore's (1993) utilization of Mackenzie's (1979) game DC, means of using computational agents as the test-bed to facilitate evaluation of the proposed model, and means of using the evaluation results as motivation to further develop a dialogue model, which can prevent fallacious argument and common errors. It is anticipated that this work will contribute toward the development of human (...) computer dialogue, and help to illuminate research issues in the field of dialectics itself. (shrink)

This book argues that the moral quality of an act comes from the agent's inner states. By arguing for the indispensable relevance of intention in the moral evaluation of acts, the book moves against a mainstream, 'objective' approach in normative ethics. It is commonly held that the intentions, knowledge, and volition of agents are irrelevant to the moral permissibility of their acts. This book stresses that the capacities of agency, rather than simply the label 'agent', must be (...) engaged during an act if its moral evaluation is to be coherent. The author begins with an ontological argument that an act is a motion or a causing of change in something else. He argues that the source of an act's moral meaning is in the agent: specifically, what the agent, if aware of relevant facts around her, aims to accomplish. He then moves to a series of critical chapters that consider arguments for mainstream approaches to act evaluation, including Thomson's dismissal of the agent knowledge and volition requirements, Scanlon's arguments for a derivative relevance of intentions to permissibility, Frowe's "causal roles" of agents in the moral evaluation of acts, and Bennett's explicit defense of the objective approach. The book concludes by offering the author's preferred replacement for the objective approach, an Aristotelian-Thomist view of acts. Acts, Intentions, and Moral Evaluation will be of interest to scholars and advanced students working in ethics, just war theory, the ethics of self-defense, and philosophy of action. (shrink)

This paper evaluates the current use of the Principal Agent Model (PAM) in accounting and finance, focusing on the agent'ss use of private information. The agent'ss behavioral norms in the the PAM deviate from commonly held ethical values in society, from models of man in conventional economic theory, and also from behavioral foundations of related business school fields like corporate strategy, business ethics, and human resource management. Still, it would be unwise to reject the PAM solely because (...) of its distasteful ethical assumptions. The model does appear to have predictive power, but its descriptive or normative qualities remain unexplored. The popularity of the PAM, with its extreme model of man, raises fundamental questions about the impact of this model on business school stakeholders and society at large. (shrink)

This paper provides a sketch of an agent-centered way of understanding and answering the question, “What’s wrong with that?” On this view, what lies at the bottom of judgments of wrongness is a bad attitude; when someone does something wrong, she does something that expresses a bad, or inappropriate, attitude . In order to motivate this account, a general Kantian agent-centered ethics is discussed, as well as Michael Slote’s agent-based ethics, in light of analysis of the grounding (...) role of attitudes in the evaluation of two core cases. In light of these discussions, it is argued that there are advantages to preserving the grounding of the appropriateness of attitudes in facts about their objects , while cutting such an agent-centered ethics away from a Kantian grounding.

Agents and agent-based systems are becoming essential in the development of various fields, such as artificial intelligence, ubiquitous computing, ambient intelligence, autonomous computing, and intelligent robotics. The concept of autonomous agents, inspired by the observed agency in living systems, is also central to current theories on the origin, development, and evolution of life. Therefore, it is crucial to develop an accurate understanding of agents and the concept of agency. This paper begins by discussing the role of agency in natural (...) systems as an inspiration and motivation for agential technologies and then introduces the idea of artificial agents. A systematic approach is presented for the classification of artificial agents. This classification aids in understanding the existing state of the artificial agents and projects their potential future roles in addressing specific types of problems with dedicated agent types.

A fiction may prescribe imagining that a pig can talk or tell the future. A fiction may prescribe imagining that torturing innocent persons is a good thing. We generally comply with imaginative prescriptions like the former, but not always with prescriptions like the latter: we imagine non-evaluative fictions without difficulty but sometimes resist imagining value-rich fictions. Thus arises the puzzle of imaginative resistance. Most analyses of the phenomenon focus on the content of the relevant imaginings. The present analysis focuses instead (...) on the character of certain kinds of imaginings, arguing that we resist in such cases given the rich evaluative character of the imaginings prescribed, and the agent-dependent constraints on imagining in such ways.

This article contributes to the literature on the evaluation of sets of opportunities. The starting point is Lancaster's characteristics approach. However, instead of assuming the existence of a canonical utility function, a reference point or reference level is postulated from which an agent evaluates set expansions in appropriate directions. One of the major tools for this exercise is the notion of directed cones. Desirability of characteristics is restricted to the interior of these cones. Satiation and non-monotonic evaluation (...) is considered as well. An axiomatic characterization for various cases is provided. (shrink)

In a digital communication environment, information security is mandatory. Three essential parameters used in the design process of a steganography algorithm are Payload, security, and fidelity. However, several methods are implemented in information hiding, such as Least Significant Bit (LBS), Discrete Wavelet Transform, Masking, and Discrete Cosine Transform. The paper aims to investigate novel steganography techniques based on agent technology. It proposes a Framework of Steganography based on agent for secret communication using LSB. The most common image steganography (...) databases are explored for training and testing. The methodology in this work is based on the statistical properties of the developed agent software using Matlab. The experiment design is based on six statistical feature measures, including Histogram, Mean, Standard deviation, Entropy, Variance and Energy. For steganography, an Ensemble classifier is used to test two scenarios: embedding a single language message and inserting bilingual messages. ROC Curve represents the evaluation metrics. The result shows that the designed agent-based system with 50% training/testing sample set and 0.2 Payload can pick out the best cover image for the provided hidden message size to avoid visual artifact.

Cognitive agents form beliefs representing the world, evaluate the world as represented, form plans for making the world more to their liking, and perform actions executing the plans. Then the cycle repeats. This is the doxastic-conative loop, diagrammed in figure one.1 Both human beings and the autonomous rational agents envisaged in AI are cognitive agents in this sense. The cognition of a cognitive agent can be subdivided into two parts. Epistemic cognition is that kind of cognition responsible for producing (...) and maintaining beliefs. Practical cognition evaluates the world, adopts plans, and initiates action. There is a massive literature both in philosophy and artificial intelligence concerning various aspects of epistemic cognition, and large parts of it are well understood. Practical cognition is less well understood. We can usefully divide practical cognition into five parts: (1) the evaluation of the world as represented by the agent’s beliefs, (2) the adoption of goals for changing it, (3) the construction of plans for achieving goals, (4) the adoption of plans, and (5) the execution of plans. There is a substantial literature in AI concerning the construction and execution of plans, and I will say nothing further about those topics here. This paper will focus on the evaluative aspects of practical cognition. Evaluation plays an essential role in both goal selection and plan adoption. My concern here is the investigation of evaluation as a cognitive enterprise performed by cognitive agents. I am interested both in how it is performed in human beings and how it might be performed in artificial rational agents. (shrink)

We introduce a new operator, called rational evaluation, in belief change. The operator evaluates new information according to the agent’s core beliefs, and then exports the plausible part of the new information. It belongs to the decision module in belief change. We characterize rational evaluation by axiomatic postulates and propose two functional constructions for it, based on the well-known constructions of kernel sets and remainder sets, respectively. The main results of the paper are two representation theorems with (...) respect to the two functional constructions. We also compare and connect the evaluation operator with some related operators in belief revision, including contraction, set contraction, and prioritized multiple revision. (shrink)

This paper describes a study of the effects of two acts of social intelligence, namely mimicry and social praise, when used by an artificial social agent. An experiment ( N = 50) is described which shows that social praise—positive feedback about the ongoing conversation—increases the perceived friendliness of a chat-robot. Mimicry—displaying matching behavior—enhances the perceived intelligence of the robot. We advice designers to incorporate both mimicry and social praise when their system needs to function as a social actor. Different (...) ways of implementing mimicry and praise by artificial social actors in an ambient persuasive scenario are discussed. (shrink)

This article examines if bottom-up artificial moral agents are capable of making genuine moral judgements, specifically in light of David Hume’s is-ought problem. The latter underscores the notion that evaluative assertions could never be derived from purely factual propositions. Bottom-up technologies, on the other hand, are those designed via evolutionary, developmental, or learning techniques. In this paper, the nature of these systems is looked into with the aim of preliminarily assessing if there are good reasons to suspect that, on the (...) foundational level, their moral reasoning capabilities are prone to the no-ought-from-is thesis. The main hypothesis of the present work is that, by conceptually analysing the notion of bottom-up artificial moral agents, it would be revealed that their seeming moral judgements do not have proper philosophical basis. For one, the said kinds of artifacts arrive at the understanding of ethically-relevant ideas by means of culling data or facts from the environment. Thus, in relation to the is-ought problem, it may be argued that, even if bottom-up systems seem prima facie capable of generating apparent moral judgments, such are actually absent of good moral grounding, if not empty of any ethical value.

In ‘Moral Luck,’ Bernard Williams famously argued that “there is a particularly important species of regret, which I shall call ‘agent-regret,’ which a person can feel only towards his past actions.” Much subsequent commentary has focused on Williams’s claim that agent-regret is not necessarily restricted to voluntary actions, and questioned whether such an attitude could be rationally justified. This focus, however, obscures a more fundamental set of questions raised by Williams’s discussion: what is the role in our moral (...) psychology of evaluative attitudes that relate essentially to past exercises of our agency—occurrences which, by their very nature, cannot be repeated? On a standard conception, regret is directed principally towards actions that resulted from suboptimal deliberation. On this view, the main point of regret is to guide us away from similar poor decisions in the future. But Williams’s key insight in ‘Moral Luck,’ I argue, is that there is a mode of evaluation of one’s past actions and decisions that does not track considerations one could and should have been responsive to at the time, and is for this reason essentially retrospective. From this perspective, the full significance of regret cannot be captured in terms of a disposition to deliberate better in the future. Rather, the particular kind of painful of consciousness of the past embodied in regret amounts to a reflective, and essentially backward-looking, insight into the contingency and finitude of our own agency—that I am a particular person leading a particular life, and that the possibility of leading a different life is now gone forever. I end by making some speculative comments about the intractable question whether it is ultimately good or desirable to be disposed to regret one’s past mistakes. (shrink)

Accidie, depression, and dejection seem to be psychological phenomena that are best characterized as cases in which an agent has no motivation to pursue what he or she judges to be good or valuable.

In the standard theory of deontic modals, ‘ought’ is understood as expressing a propositional operator. However, this view has been called into question by Almotahari and Rabern’s puzzle about deontic ‘ought’, according to which the ethical principle that one ought to be wronged by another person rather than wrong them is intuitively coherent but the standard theory makes it incoherent. In this paper, I take up Almotahari and Rabern’s challenge and offer a refinement of the standard theory to handle the (...) puzzle. I propose that ‘ought’ is evaluated relative to contextual parameters (e.g., Kratzer’s conversational backgrounds, Finlay and Snedegar’s alternative sets) and those contextual parameters are sensitive to agents as well as possible worlds.

Purpose: This article looks at the role played by agents: the people responsible for articulating and implementing inculturation in Africa. The article asks the simple question of are these agents useful or a hindrance in the process of inculturation? The article begins by identifying these agents then discusses the challenges they face in the process of inculturation. The article concludes by giving a way forward and that is an integrated approach in inculturation.Methodology: This study will review the available literature on (...) the subject with a view to examining what previous research says concerning the role of the agents, that is human beings, in the process of inculturation. This was done with the main objective of examining the challenges that he agents of inculturation face, and concluding by exploring an integrated approach to inculturation, where all the agents are brought on board. Findings: This study found out that if inculturation is to truly take root in African Christianity, it must bring on board all actors, not just Church leaders, and trained theologians, but also the laity. All these actors also need to overcome some of the challenges that have hindered the prospects of inculturation which include but not limited to fear of syncretism, lack of enthusiasm by some Church leaders, answering the question of culture in a post-modern and globalized world.Unique Contribution to Theory, Practice and Policy: This paper will offer unique contributions to policies and practices governing the attempts to make the Church in Africa truly African by proposing a re-evaluation of the way inculturation has been carried out in the past. This has tended to be spearheaded by professional theologians and some church leaders, neglecting the biggest constituency in the entire process, and that is the consumer of inculturational processes; the laity.

The article presents the nature of shared intentions and collective responsibility in simultaneous discussion of individualism, which views that collective agents and shared intentions are to be analyzed in relation between individual agents who are members of the collectives. It discusses as well the agent meaning theory that states that an agent moves against the interpretive background of action evaluation shared by the agent and the moral community.

This thesis develops a theory about the structure of modal judgment and knowledge. Arguing in favour of pluralism about the source of modal knowledge, it focuses on the questions of the varieties of modal judgment and their relations, the function of modal judgment and the scope of modal knowledge. It offers a hypothesis about the development of the framework of modal knowledge, grounding it on the capacity to evaluate temporal judgments, from which the capacity to evaluate alternatives comes from, and (...) it suggests that the most basic framework of modal judgments consists in that of agentive modality, and in particular, about what one can do, and how. Then, it is argued that the rest of the framework of modal judgment can be developed on this basis, although this imposes certain restrictions about the scope of modal knowledge. Additionally, the thesis provides analyses of various agentive modal notions, such as imaginability, what is a way to do something, and discusses how to understand counterfactuals with impossible antecedents.

This paper contributes to the foundations of a theory of rational choice for artificial agents in dynamic environments. Our work is developed within a theoretical framework, originally due to Bratman, that models resource-bounded agents as operating against the background of some current set of intentions, which helps to frame their subsequent reasoning. In contrast to the standard theory of rational choice, where options are evaluated in isolation, we therefore provide an analysis of situations in which the options presented to an (...) agent are evaluated against a background context provided by the agent’s current plans—commitments to future activities, which may themselves be only partially specified. The interactions between the new options and the background context can complicate the task of evaluating the option, rendering it either more or less desirable in context than it would have been in isolation.  2001 Elsevier Science B.V.

Resumo O objetivo do texto é relacionar a abordagem expressivista do agente moral em Nietzsche com as condições de sucesso de avaliação de juízos práticos perfeccionistas. Como locus da transformação, o agente moral se exprime por meio do potencial transformativo que consegue produzir, e não como entidade por trás das ações. Duas condições podem ser usadas, regulativamente, para avaliar o sucesso de juízos de caráter perfeccionista: por um lado, a maximização de conexões e interrelações no espaço, bem como o endosso (...) afirmativo de promessas no tempo e, por outro lado, a boa constituição que alguém mantém em meio à tensão entre um plano individual e supraindividual. No desdobramento do potencial transformativo, crítica e transformação são interdependentes e, além disso, o julgamento público reforça a dimensão social da filosofia de Nietzsche.The aim of the text is to relate the expressivist approach of the moral agency in Nietzsche to the conditions for successful evaluation of practical perfectionist judgments. As the locus of transformation, the moral agent expresses him/herself in the transformative potential that he/she manages to produce, and not as an entity behind the actions. Two conditions can be used, regulatively, to evaluate the success of perfectionist judgments: on the one hand, the maximization of connections and interrelationships in space, as well as the affirmative endorsement of promises in time, and, on the other hand, the good constitution one keeps in the middle of the tension between an individual and supraindividual plan. In the unfolding of transformative potential, criticism and transformation are interdependent and, moreover, public judgment reinforces the social dimension of Nietzsche's philosophy. (shrink)

Imagination contributes to human agency in ways that haven't been well understood. I argue here that pathways from imagistic imagining to emotional engagement support three important agential capacities: 1. bodily preparedness for potential events in one's nearby environment; 2. evaluation of potential future action; and 3. empathy-based moral appraisal. Importantly, however, the kind of pathway in question (I-C-E-C: imagining-categorization-emotion-conceptualization) also enables engagement with fiction. So human enchantment with fiction is a consequence of imaginative pathways that make us the kind (...) of agents we are. Finally, I use this approach to address imaginative resistance and the paradox of fiction. [The version archived here is a penultimate draft.

The study ascertained (1) whether an observer's scope of justice with reference to either the moral agent or the target person of a moral act, would affect his/her judgements of the ethicality of the act, and (2) whether observer judgements of ethicality parallel the moral agent's decision processes in systematically evaluating the intensity of the moral issue. A scenario approach was used. Results affirmed both research questions. Discussions covered the implications of the findings for the underlying cognitive processes (...) of moral judgements, for the link between judgements of fairness and ethicality, as well as for the debate of ethical absolutism versus relativism.

This paper presents the intelligent virtual animals that inhabit Omosa, a virtual learning environment to help secondary school students learn how to conduct scientific inquiry and gain concepts from biology. Omosa supports multiple agents, including animals, plants, and human hunters, which live in groups of varying sizes and in a predator-prey relationship with other agent types (species). In this paper we present our generic agent architecture and the algorithms that drive all animals. We concentrate on two of our (...) animals to present how different parameter values affect their movements and inter/intra-group interactions. Two evaluations studies are included: one to demonstrate the effect of different components of our architecture; another to provide domain expert validation of the animal behavior. (shrink)

Agent-Based Models are useful to describe and understand social, economic and spatial systems' dynamics. But, beside the facilities which this methodology offers, evaluation and comparison of simulation models are sometimes problematic. A rigorous conceptual frame needs to be developed. This is in order to ensure the coherence in the chain linking at the one extreme the scientist's hypotheses about the modeled phenomenon and at the other the structure of rules in the computer program. This also systematizes the model (...) design from the thematician conceptual framework as well. The aim is to reflect upon the role that a well defined ontology, based on the crossing of the philosophical and the computer science insights, can play to solve such questions and help the model building. We analyze different conceptions of ontology, introduce the 'ontological test' and show its usefulness to compare models. Then we focus on the model building and show the place of a systematic ABM ontology. The latter process is situated within a larger framework called the 'knowledge framework' in which not only the ontologies but also the notions of theory, model and empirical data take place. At last the relation between emergence and ontology is discussed. (shrink)

Artificial models of cognition serve different purposes, and their use determines the way they should be evaluated. There are also models that do not represent any particular biological agents, and there is controversy as to how they should be assessed. At the same time, modelers do evaluate such models as better or worse. There is also a widespread tendency to call for publicly available standards of replicability and benchmarking for such models. In this paper, I argue that proper evaluation (...) ofmodels does not depend on whether they target real biological agents or not; instead, the standards of evaluation depend on the use of models rather than on the reality of their targets. I discuss how models are validated depending on their use and argue that all-encompassing benchmarks for models may be well beyond reach. (shrink)
