The paper presents a novel view of social norms that reflects the importance of different agent types, their specific motivations and roles. How one identifies with a role and behavioral options available to the agent is crucial for the sustainability of the social norms. The analysis of a simple case of social norm is suggested as a default model for analysis, and then the classification of subjects, enforcers, and audience is introduced. This triangular typology of agents is (...) extended by introducing a network of interlocking patterns underlying social behavior. Lastly, the paper describes two categories of transgressions based on misidentification. (shrink)

In this paper, we first propose a simple formal language to specify types of agents in terms of necessary conditions for their announcements. Based on this language, types of agents are treated as ‘first-class citizens’ and studied extensively in various dynamic epistemic frameworks which are suitable for reasoning about knowledge and agent types via announcements and questions. To demonstrate our approach, we discuss various versions of Smullyan’s Knights and Knaves puzzles, including the Hardest Logic Puzzle Ever (...) (HLPE) proposed by Boolos (in Harv Rev Philos 6:62–65, 1996). In particular, we formalize HLPE and verify a classic solution to it. Moreover, we propose a spectrum of new puzzles based on HLPE by considering subjective (knowledge-based) agent types and relaxing the implicit epistemic assumptions in the original puzzle. The new puzzles are harder than the previously proposed ones in the literature, in the sense that they require deeper epistemic reasoning. Surprisingly, we also show that a version of HLPE in which the agents do not know the others’ types does not have a solution at all. Our formalism paves the way for studying these new puzzles using automatic model checking techniques. (shrink)

In this issue of Philosophical Studies, Richard Arneson, Jonathan Quong and Robert Talisse contribute papers discussing The Order of Public Reason (OPR). All press what I call “agent-type challenges” to the project of OPR. In different ways they all focus on a type (or types) of moral (or sometimes not-so-moral) agent. Arneson presents a good person who is so concerned with doing the best thing she does not truly endorse social morality; Quong a bad person who rejects (...) it and violates the basic rights of others, and Talisse a morally ugly person, a hypocrite, who criticizes others for failing to do what he does not do. All suggest that OPR does not give a satisfying account of what we are to say to, or how we should act towards, such agents. In my response I highlight some core concerns of OPR, while also seeking to show that OPR does not say quite what they think it says, and it often leaves them room for saying what they would like to say about such agents.

The main task is to discuss the issue in belief dynamics in which philosophical beliefs and rational introspective agents incorporate Moorean type new information. First, a brief survey is conducted on Moore’s Paradox, and one of its solutions is introduced with the help of Update Semantics. Then, we present a Dynamic Doxastic Logic (DDL) which revises the belief of introspective agents put forward by Lindström & Rabinowicz. Next, we attempt to incorporate Moorean type new information within the DEL (DDL) framework, (...) as advised by van Benthem, Segerberg et al. Though we maintain the principle of “the primacy of new information” from the literature on traditional belief revision theory, several unsuccessful ways are also presented. We then conclude that some special kind of success (weak success) can still be found in those revision processes although absolute success does not hold. At last, the relevant problem of “learnability” is re-considered through weak success. (shrink)

Agent communication languages (ACLs) invoke speech act theory and define individual message types by reference to particular combinations of beliefs and desires of the speaker (feasibility preconditions). Even when the mental states are restricted to a small set of nested beliefs, it seems that there might be a very large number of different possible preconditions, and therefore a very large number of different message types. With some constraints on the mental attitude of the speaker, we enumerate the (...) possible belief states that could serve as preconditions for individual message types, and we identify how these states correspond to different possible message types. We then compare these with FIPA’s primitive message types. Our approach clarifies the nature of core message types in an ACL, and perhaps settles issues concerning just how many, and what types of, speech acts should be seen as primitive in such languages.

While philosophers hold that it is patently absurd to blame robots or hold them morally responsible [1], a series of recent empirical studies suggest that people do ascribe blame to AI systems and robots in certain contexts [2]. This is disconcerting: Blame might be shifted from the owners, users or designers of AI systems to the systems themselves, leading to the diminished accountability of the responsible human agents [3]. In this paper, we explore one of the potential underlying reasons for (...) robot blame, namely the folk's willingness to ascribe inculpating mental states or "mens rea" to robots. In a vignette-based experiment (N=513), we presented participants with a situation in which an agent knowingly runs the risk of bringing about substantial harm. We manipulated agent type (human v. group agent v. AI-driven robot) and outcome (neutral v. bad), and measured both moral judgment (wrongness of the action and blameworthiness of the agent) and mental states attributed to the agent (recklessness and the desire to inflict harm). We found that (i) judgments of wrongness and blame were relatively similar across agent types, possibly because (ii) attributions of mental states were, as suspected, similar across agent types. This raised the question - also explored in the experiment - whether people attribute knowledge and desire to robots in a merely metaphorical way (e.g., the robot "knew" rather than really knew). However, (iii), according to our data people were unwilling to downgrade to mens rea in a merely metaphorical sense when given the chance. Finally, (iv), we report a surprising and novel finding, which we call the inverse outcome effect on robot blame: People were less willing to blame artificial agents for bad outcomes than for neutral outcomes. This suggests that they are implicitly aware of the dangers of overattributing blame to robots when harm comes to pass, such as inappropriately letting the responsible human agent off the moral hook.

In this chapter we reflect on questions about the nature and sources of agentive phenomenology – that is, the set of those experience-types associated with exercises of agency, and paradigmatically with intentional actions. Our discussion begins with pioneering work in psychology and neuroscience that dates to the early 80s (section 1). As we will see, much of the current work on agentive phenomenology in both psychology and philosophy draws motivation from this work, and the questions it raises. After discussing (...) empirical work relevant to agentive phenomenology, we turn to consideration of its nature. We cover questions about the scope of agentive phenomenology, about its relationship to other types of experiences (section 2.1), about the best way to characterize aspects of agentive phenomenology, and about the function of various types of agentive experience (section 2.2).

In the literature there are at least two main formal structures to deal with situations of interactive epistemology: Kripke models and type spaces. As shown in many papers :149–225, 1999; Battigalli and Siniscalchi in J Econ Theory 106:356–391, 2002; Klein and Pacuit in Stud Log 102:297–319, 2014; Lorini in J Philos Log 42:863–904, 2013), both these frameworks can be used to express epistemic conditions for solution concepts in game theory. The main result of this paper is a formal comparison between (...) the two and a statement of semantic equivalence with respect to two different logical systems: a doxastic logic for belief and an epistemic–doxastic logic for belief and knowledge. Moreover, a sound and complete axiomatization of these logics with respect to the two equivalent Kripke semantics and type spaces semantics is provided. Finally, a probabilistic extension of the result is also presented. A further result of the paper is a study of the relationship between the epistemic–doxastic logic for belief and knowledge and the logic STIT by Belnap and colleagues. (shrink)

This study provides a basic introduction to agent-based modeling (ABM) as a powerful blend of classical and constructive mathematics, with a primary focus on its applicability for social science research. The typical goals of ABM social science researchers are discussed along with the culture-dish nature of their computer experiments. The applicability of ABM for science more generally is also considered, with special attention to physics. Finally, two distinct types of ABM applications are summarized in order to illustrate concretely (...) the duality of ABM: Real-world systems can not only be simulated with verisimilitude using ABM; they can also be efficiently and robustly designed and constructed on the basis of ABM principles.

Now that complex Agent-Based Models and computer simulations spread over economics and social sciences - as in most sciences of complex systems -, epistemological puzzles (re)emerge. We introduce new epistemological concepts so as to show to what extent authors are right when they focus on some empirical, instrumental or conceptual significance of their model or simulation. By distinguishing between models and simulations, between types of models, between types of computer simulations and between types of empiricity obtained (...) through a simulation, section 2 gives the possibility to understand more precisely - and then to justify - the diversity of the epistemological positions presented in section 1. Our final claim is that careful attention to the multiplicity of the denotational powers of symbols at stake in complex models and computer simulations is necessary to determine, in each case, their proper epistemic status and credibility.

It is commonly held that all deontological moral theories are agent-relative in the sense that they give each agent a special concern that she does not perform acts of a certain type rather than a general concern with the actions of all agents. Recently, Tom Dougherty has challenged this orthodoxy by arguing that agent-neutral deontology is possible. In this article I counter Dougherty's arguments and show that agent-neutral deontology is not possible.

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.

Talk of different types of cells is commonplace in the biological sciences. We know a great deal, for example, about human muscle cells by studying the same type of cells in mice. Information about cell type is apparently largely projectible across species boundaries. But what defines cell type? Do cells come pre-packaged into different natural kinds? Philosophical attention to these questions has been extremely limited [see e.g., Wilson (Species: New Interdisciplinary Essays, pp 187–207, 1999; Genes and the Agents of (...) Life, 2005; Wilson et al. Philos Top 35(1/2):189–215, 2007)]. On the face of it, the problems we face in individuating cellular kinds resemble those biologists and philosophers of biology encountered in thinking about species: there are apparently many different (and interconnected) bases on which we might legitimately classify cells. We could, for example, focus on their developmental history (a sort of analogue to a species’ evolutionary history); or we might divide on the basis of certain structural features, functional role, location within larger systems, and so on. In this paper, I sketch an approach to cellular kinds inspired by Boyd’s Homeostatic Property Cluster Theory, applying some lessons from this application back to general questions about the nature of natural kinds.

There is, on a given moral view, an agent-centered restriction against performing acts of a certain type if that view prohibits agents from performing an instance of that act-type even to prevent two or more others from each performing a morally comparable instance of that act-type. The fact that commonsense morality includes many such agent-centered restrictions has been seen by several philosophers as a decisive objection against consequentialism. Despite this, I argue that agent-centered restrictions are more plausibly (...) accommodated within a consequentialist framework than within the more standard side-constraint framework. For I argue that when we combine agent-relative consequentialism with a Kantian theory of value, we arrive at a version of consequentialism, which I call 'Kantsequentialism', that has several advantages over the standard side-constraint approach to accommodating constraints. What’s more, I argue that Kantsequentialism doesn’t have any of the disadvantages that critics of consequentializing have presumed that such a theory must have. (shrink)

In this paper, I argue that the conscious awareness one has of oneself as acting, i.e., agentive awareness, is not a type of sensory awareness. After providing some set up in Sect. 1, I move on in Sect. 2 to sketch a profile of sensory agentive experiences as representational states with sensory qualities by which we come to be aware of ourselves as performing actions. In Sect. 3, I critique two leading arguments in favor of positing such sensory experiences: the (...) argument from pathology and the argument from cognitive impenetrability. Since neither of these arguments succeeds, the case for positing SAEs is dealt a significant blow. I proceed in Sect. 4 to advance my positive argument against SAEs. The argument runs as follows: If SAEs exist, then they must exist in some sensory modality or set of sensory modalities. Either the relevant sensory modalities are ones that we already recognize, or they are novel sensory modalities. I will argue that neither of these options is workable, and so we have nowhere to locate SAEs. Agentive awareness is not sensory awareness. (shrink)

Agent-based modeling has become a common and well-established tool in the social sciences and certain of the humanities. Here, we aim to provide an overview of the different modeling approaches in current use. Our discussion unfolds in two parts: we first classify different aspects of the model-building process and identify a number of characteristics shared by most agent-based models in the humanities and social sciences; then we map relevant differences between the various modeling approaches. We classify these into (...) different dimensions including the type of target systems addressed, the intended modeling goals, and the models’ degree of abstraction. Along the way, we provide reference to related debates in contemporary philosophy of science. (shrink)

Many philosophers are persuaded by familiar arguments that free will is incompatible with causal determinism. Yet, notoriously, past attempts to articulate how the right type of indeterminism might secure the capacity for autonomous action have generally been regarded as either demonstrably inadequate or irremediably obscure. This volume gathers together the most significant recent discussions concerning the prospects for devising a satisfactory indeterministic account of freedom of action. These essays give greater precision to traditional formulations of the problems associated with indeterministic (...) accounts and to the range of theoretical avenues for pursuing resolutions. The first four essays set out different challenges (from both compatibilists and those skeptical of the possibility of free will) to the adequacy of standard indeterministic theories. The next seven essays meet one or more of these challenges. Each of the fundamental types of approach--simple indeterminism, causal indeterminism, and agent causation--is represented in these novel and sophisticated proposals. The collection finishes with two essays that debate whether compatibilism entails that freedom of choice is a comparatively rare phenomenon within an individual's life. Eloquently presenting some of the most compelling and accessible arguments surrounding this central philosophical issue, Agents, Causes, and Events makes a valuable contribution to courses in free will/action theory and metaphysics.

An idea that has attracted a lot of attention lately is the thought that consequentialism is a theory characterized basically by its agent neutrality.1 The idea, however, has also met with skepticism. In particular, it has been argued that agent neutrality cannot be what separates consequentialism from other types of theories of reasons for action, since there can be agent-neutral non-consequentialist theories as well as agent-relative consequentialist theories. I will argue in this paper that this (...) last claim is false. The paper is divided into four sections. Section one specifies two senses in which consequentialism is agent-neutral. Section two and three examine and reject, respectively, the claim that there are agent-relative consequentialist views as well as agent-neutral non-consequentialist views. I end the paper with some remarks on the plausibility, or better, the implausibility of characterizing consequentialism in terms other than agent neutrality. (shrink)

According to the “Textbook View,” there is an extensional dispute between consequentialists and deontologists, in virtue of the fact that only the latter defend “agent-relative” principles—principles that require an agent to have a special concern with making sure that she does not perform certain types of action. I argue that, contra the Textbook View, there are agent-neutral versions of deontology. I also argue that there need be no extensional disagreement between the deontologist and consequentialist, as characterized (...) by the Textbook View. (shrink)

By distinguishing between models and simulations, between types of models, between types of computer simulations and between types of (...) empiricity, section 2 gives conceptual tools to explain the rationale of the diverse epistemological positions presented in section 1. Finally, we claim that a careful attention to the real multiplicity of denotational powers of symbols at stake and then to the implicit routes of references operated by models and computer simulations is necessary to determine, in each case, the proper epistemic status and credibility of a given model and/or simulation.

Agent-based models (ABMs) are one type of simulation model used in the context of the COVID-19 pandemic. In contrast to equation-based models, ABMs are algorithms that use individual agents and attribute changing characteristics to each one, multiple times during multiple iterations over time. This paper focuses on three philosophical aspects of ABMs as models of causal mechanisms, as generators of emergent phenomena, and as providers of explanation. Based on my discussion, I conclude that while ABMs cannot help much with (...) causal inference, they can be viewed as etio-prognostic explanations of illness occurrence and outcome. (shrink)

Where artificial agents are not liable to be ascribed true moral agency and responsibility in their own right, we can understand them as acting as proxies for human agents, as making decisions on their behalf. What I call the ‘Moral Proxy Problem’ arises because it is often not clear for whom a specific artificial agent is acting as a moral proxy. In particular, we need to decide whether artificial agents should be acting as proxies for low-level agents — e.g. (...) individual users of the artificial agents — or whether they should be moral proxies for high-level agents — e.g. designers, distributors or regulators, that is, those who can potentially control the choice behaviour of many artificial agents at once. Who we think an artificial agent is a moral proxy for determines from which agential perspective the choice problems artificial agents will be faced with should be framed: should we frame them like the individual choice scenarios previously faced by individual human agents? Or should we, rather, consider the expected aggregate effects of the many choices made by all the artificial agents of a particular type all at once? This paper looks at how artificial agents should be designed to make risky choices, and argues that the question of risky choice by artificial agents shows the moral proxy problem to be both practically relevant and difficult.

To address what I call the “Uniformity”, “Capriciousness”, and “Reducibility” objections, recent agent-causation theories hold that agent-causation is a type of substance causation. Substance causation consists in substances producing effects by exercising or manifesting their powers. Importantly, these versions of agent-causation assume a realist metaphysics of powers, where powers are properties of substances that can exist unmanifested. However, the realist theories of powers that agent-causal theories have relied upon explicitly hold that powers—rather than their substances—are causes. (...) Substances are merely derivative causes, as the bearers of powers. Critics therefore argue that agent-causation is reducible to causation by the agent’s powers. In this paper, I argue that agent-causation is reducible to causation by the agent’s powers only if powers are self-exemplifying properties. I also offer reasons for why powers—especially agent-causal powers—are non-self-exemplifying properties, in support of the irreducibility of agent-causation. (shrink)

Currently, two frameworks of causal reasoning compete: Whereas dependency theories focus on dependencies between causes and effects, dispositional theories model causation as an interaction between agents and patients endowed with intrinsic dispositions. One important finding providing a bridge between these two frameworks is that failures of causes to generate their effects tend to be differentially attributed to agents and patients regardless of their location on either the cause or the effect side. To model different types of error attribution, we (...) augmented a causal Bayes net model with separate error sources for causes and effects. In several experiments, we tested this new model using the size of Markov violations as the empirical indicator of differential assumptions about the sources of error. As predicted by the model, the size of Markov violations was influenced by the location of the agents and was moderated by the causal structure and the type of causal variables. (shrink)

Collaboration requires agents to coordinate their behavior on the fly, sometimes cooperating to solve a single task together and other times dividing it up into sub‐tasks to work on in parallel. Underlying the human ability to collaborate is theory‐of‐mind (ToM), the ability to infer the hidden mental states that drive others to act. Here, we develop Bayesian Delegation, a decentralized multi‐agent learning mechanism with these abilities. Bayesian Delegation enables agents to rapidly infer the hidden intentions of others by inverse (...) planning. We test Bayesian Delegation in a suite of multi‐agent Markov decision processes inspired by cooking problems. On these tasks, agents with Bayesian Delegation coordinate both their high‐level plans (e.g., what sub‐task they should work on) and their low‐level actions (e.g., avoiding getting in each other's way). When matched with partners that act using the same algorithm, Bayesian Delegation outperforms alternatives. Bayesian Delegation is also a capable ad hoc collaborator and successfully coordinates with other agent types even in the absence of prior experience. Finally, in a behavioral experiment, we show that Bayesian Delegation makes inferences similar to human observers about the intent of others. Together, these results argue for the centrality of ToM for successful decentralized multi‐agent collaboration. (shrink)

This article begins by identifying three key features of the traditional approach to defense and shows how these features reflect ideas from our philosophical tradition. It then presents an interpersonal reconceptualization of defense, which is guided by an alternative philosophical perspective based on what Merleau–Ponty referred to as "involved subjectivity." This reconceptualization, or theory of "interpersonal defense," calls for viewing defense primarily as interpersonal behavior, attending to the functional role it plays in ongoing interactions, and recognizing that defensive behavior is (...) a special type of problematic interpersonal pattern. Interpersonal defenses often are quite effective when it comes to avoiding clear-cut versions of feared interaction outcomes, but they make it virtually impossible for clear-cut versions of wished-for outcomes to occur, promote indirect versions of feared outcomes, and lead to highly distorted forms of wished-for consequences. They are characterized by a failure in how individuals integrate their behaviors in the context of interactions in which they are engaged as participants. This is a breach precisely in what the alternative philosophical perspective takes to be the core of human behavior. Defense represents a struggle against the person’s fundamental involvement in the world, and viewing it in this light helps us understand concrete features of the phenomena of interest. Implications of the theory of interpersonal defense for research and practice are discussed, including using discourse analysis to operationalize defensive behavior. The article concludes with the suggestion that the basis for defense involves a "fundamental fault-line" in human nature which concerns a delicate balance between integrating our actions in the contexts that make up our lives and attempting to control constraints of those situations.

Propositional attitudes, such as beliefs, desires, and intentions, can be attributed to collective agents. In my paper I focus on cognitive attitudes, and I explore the various types of collective beliefs. I argue that there is a whole spectrum of collective beliefs, and I distinguish between two extremes: the weak opinion poll conception and the strong agreement-based conception. Strong collective beliefs should be understood in terms of the acceptance of a proposition rather than of belief proper. They are not (...) purely epistemic and involve practical considerations. To believe that p collectively in the strong sense is to adopt a policy to use that proposition in the group’s deliberations about future actions. (shrink)

Here, I put forward a new account of how experience gives rise to the belief that time passes. While there is considerable disagreement amongst metaphysicians as to whether time really does pass, it has struck many as a default, ‘common sense’ way of thinking about the world. A popular way of explaining how such a belief arises is to say that it seems perceptually as though time passes. Here I outline some difficulties for this approach, and propose instead that the (...) belief in time passing is elicited by a particular feature of agentive experience. When we deliberately move our bodies, bring something to mind, or focus our attention, we experience ourselves as the sources of these actions. Sensing oneself as a source, I argue, is a unique type of change experience, one which leads us to a belief that time is passing. (shrink)

We develop and defend a distinction between two types of self-censorship: public and private. First, we suggest that public self-censorship refers to a range of individual reactions to a public censorship regime. Second, private self-censorship is the suppression by an agent of his or her own attitudes where a public censor is either absent or irrelevant. The distinction is derived from a descriptive approach to self-censorship that asks: who is the censor, who is the censee, and how do (...) they interact? We label situations in which censor and censee are different agents as public self-censorship, and situations in which they are the same agents as private self-censorship. We demonstrate the salience of this distinction by analysing the case of publication of Mohammed cartoons by the Danish newspaper Jyllands-Posten. Our analysis reveals the presence and interaction of a number of different instances of private and public self-censorship. While our article is primarily concerned with establishing this novel descriptive distinction between public and private self-censorship, our analysis has important evaluative implications. We explain for instance how Jyllands-Posten was laudable as a public self-censor but not so as a private self-censor. In general, our analysis reveals that the agents and processes involved in public and private self-censorship are substantively different, as are the agents to whom normative principles regarding censorship should be applied. In particular, principles of free speech do not apply to the case of private self-censorship, because while an instance of censorship, the absence of an external censor makes the censorship non-coercive.

In this paper, we outline a theory of the nature of self-directed agents. What is distinctive about self-directed agents is their ability to anticipate interaction processes and to evaluate their performance, and thus their sensitivity to context. They can improve performance relative to goals, and can, in certain instances, construct new goals. We contrast self-directedness with reactive action processes that are not modifiable by the agent, though they may be modified by supra-agent processes such as populational adaptation or (...) external design.Self-directedness lies at the nexus of issues concerning the evolution and nature of intentionality, intelligence, and agency. It provides some insight into the evolution of intelligence because it helps explain how organisms are able to manage variable interaction processes, e.g., a hunting strategy that varies with prey type, ground condition, and hunger level. Simple self-directed organisms like bumblebees manage variability in one or a few dimensions. (shrink)

Although the sense of agency is often reduced if not absent in dreams, our agentive dream experiences can at times be similar to or enhanced compared to waking. The sense of agency displayed in dreams is perplexing as we are mostly shut off from real stimulus whilst asleep. Theories of waking sense of agency, in particular, comparator and holistic models, are analysed in order to argue that despite the isolation from the real environment, these models can help account for dream (...) experience. The dreamer might feel an increased sense of control of their dream bodies and a sense that they can directly control elements of the dream world. Such experiences may at times be caused by superstitious or delusional thinking due to altered cognition and changes to the sleeping brain. Here it is argued that some such experiences are akin to specific waking delusions, such as delusions of grandeur, with similar cognitive features. However, other instances of increased sense of agency in dreaming appear to be sui generis and nothing like what we experience when awake. Lucid control dreams, in which the dreamer realises that they are dreaming and that they can control the dream environment, are examples of such an experience although further nuance is required to account for their specific cognitive attributes. Future empirical research should focus on controlled dream reporting conditions in order to clarify the types of experience that occur and determine the relevant cognitive mechanisms that relate to each type.

: On a standard libertarian account of free will, an agent acts freely on some occasion only if there remains, until the action is performed, some chance that the agent will do something else instead right then. These views face the objection that, in such a case, it is a matter of luck whether the agent does one thing or another. This paper considers the problem of luck as it bears on agent‐causal libertarian accounts. A view (...) of this type is defended against a recent and challenging version of the argument from luck.

Using agent‐based modelling, Harrington, Kleber, Reubold, Schiel & Stevens (2018) develop a unified model of sound change based on cognitive processing of human speech and theories of how social factors constrain the spread of change throughout a community. They conclude that many types of change result from how biases in the phonetic distribution of phonological categories are transmitted via accommodation processes between individuals in interaction.

We analyze the sequential structure of dynamic games with perfect information. A three-stage account is proposed, that species setup, reasoning and play stages. Accordingly, we define a player as a set of agents corresponding to these three stages. The notion of agent connectedness is introduced into a type-based epistemic model. Agent connectedness measures the extent to which agents' choices are sequentially stable. Thus describing dynamic games allows to more fully understand strategic interaction over time. In particular, we provide (...) suffcient conditions for backward induction in terms of agent connectedness. Also, our framework makes explicit that the epistemic independence assumption involved in backward induction reasoning is stronger than usually presumed, and makes accessible multiple-self interpretations for dynamic games. (shrink)

We conceive of a player in dynamic games as a set of agents, which are assigned the distinct tasks of reasoning and node-specific choices. The notion of agent connectedness measuring the sequential stability of a player over time is then modeled in an extended type-based epistemic framework. Moreover, we provide an epistemic foundation for backward induction in terms of agent connectedness. Besides, it is argued that the epistemic independence assumption underlying backward induction is stronger than usually presumed.

In this two-volume set, Larry D. Barnett delves into the macrosociological sources of law concerned with society-important social activities in a structurally complex, democratically governed nation. Barnett explores why, when, and where particular proscriptions and prescriptions of law on key social activities arise, persist, and change. The first volume, Societal Agents in Law: A Macrosociological Approach, puts relevant doctrines of law into a macrosociological framework, uses the findings of quantitative research to formulate theorems that identify the impact of several society-level (...) agents on doctrines of law, and takes the reader through a number of case analyses. The second volume, Societal Agents in Law: Quantitative Research, reports original multivariate statistical studies of sociological determinants of law on specific types of key social activities. Taken together, the two volumes offer an alternative to the almost-total monopoly of theory and descriptive scholarship in the macrosociology of law, comparative law, and history of law, and underscore the value of a mixed empirical/theoretical approach.

How should we understand the relationship between conscious perception and action? Does an appeal to action have any place in an account of colour experience? This essay aims to shed light on the first question by giving a positive response to the second. I consider two types of enactive approach to perceptual consciousness, and two types of account of colour perception. Each approach to colour perception faces serious objections. However, the two views can be combined in a way (...) that resists the criticisms to each. Furthermore, the hybrid view we arrive at lets us see which enactive account of perceptual consciousness we should prefer in the case of colour. (shrink)

I argue that current discussions of the epistemological significance of reflection have entangled concerns about reflection with agential concerns. I begin by showing that a central strand of internalist criticism finds externalism unsatisfactory because it fails to provide a particular kind of self-knowledge, knowledge about the epistemic status of one’s own beliefs. Identifying this internalist motivation as the desire for a kind of self-knowledge opens up new possibilities and suggests new conceptual resources. I employ one of these resources—Richard Moran’s distinction (...) between the theoretical stance and the deliberative stance—to locate two types of reflection: mere reflective awareness of one’s attitudes and agent-awareness of one’s attitudes. I then examine Ernest Sosa’s account of the importance of reflection, showing how Moran’s distinction brings out the centrality of agential concerns in Sosa’s argument for reflective knowledge. I also consider briefly its relevance to fully apt knowledge. While I focus on Sosa’s epistemology, the point extends to internalism more generally. (shrink)

Several philosophers claim that the phenomenology of one’s own agency conflicts with standard causal theories of action, couched in terms of causation by mental events or states. Others say that the phenomenology is prima facie incompatible with such a theory, even if in the end a reconciliation can be worked out. Here it is argued that the type of action theory in question is consistent with what can plausibly be said to be presented to us in our experience of our (...) agency. Several routes to a claim that there is nevertheless a prima facie incompatibility are examined, and all are found wanting. The phenomenology of agency, it is argued, is no threat to a standard causal theory of action. (shrink)

Assuming that moral discourse is prescriptive, what distinguishes it from other types of prescriptive discourse? To say, as Hare does, that it is its overridingness, is subject both to criticisms that assume that overridingness could, in principle, be used to distinguish one type of prescriptive discourse from another, and then show that it is doubtful that moral discourse is overriding, and to the criticisms that claim that it is in principle impossible to use overridingness to distinguish one type of (...) prescriptive discourse from another, because all of them are bound to be on a par in respect of overridingness. ;It is also impossible to distinguish moral discourse from other types of prescriptive discourse by saying that in it we use arguments based on imaginatively putting oneself in the shoes of others, because such arguments are used in prudential discourse as well. However, we can account for the distinction, if we realize that such arguments can be performed only on certain designated argument-places, and that in moral claims argument-places of two different types are designated for the purpose: those for moral agents and those for moral patients; while in prudential claims argument-places of only one type are designated: those for prudential agents. ;If this account is accepted, this raises a number of further questions. Examination of these questions leads to a form of relativism about membership in the sets of moral agents and moral patients. This form of relativism, however, leaves considerable room for rational discussion of membership in these sets and is compatible with the rejection of relativism about the content of moral rules.

We distinguish three qualitatively different types of uncertainty—ethical, option and state space uncertainty—that are distinct from state uncertainty, the empirical uncertainty that is typically measured by a probability function on states of the world. Ethical uncertainty arises if the agent cannot assign precise utilities to consequences. Option uncertainty arises when the agent does not know what precise consequence an act has at every state. Finally, state space uncertainty exists when the agent is unsure how to construct (...) an exhaustive state space. These types of uncertainty are characterised along three dimensions—nature, object and severity—and the relationship between them is examined. We conclude that these different forms of uncertainty cannot be reduced to empirical uncertainty about the state of the world without inducing an increase in its severity. (shrink)

In this paper, I defend the agent/patient distinction against critics who argue that causal interactions are symmetrical. Specifically, I argue that there is a widespread type of causal interaction between distinct entities, resulting in a type of ontological asymmetry that provides principled grounds for distinguishing agents from patients. The type of interaction where the asymmetry is found is when one of the entities undergoes a change in kind, structure, powers, or intrinsic properties as a result of the interaction while (...) the other does not. Interactions of this type are widespread in molecular biology and chemistry. I focus specifically on (i) the actions of enzymes on substrates and (ii) water molecules breaking the bonds of polarized molecules. Finally, I respond to objections by laying out and to a limited extent defending three commitments of my account: emergent entities and powers, realism about chemical kinds or structures, and the assumption of the agent/patient distinction in functional attributions in biology.

I examine John Martin Fischer's attempt to block an argument for the conclusion that without alternative possibilities, morally deontic judgments (judgments of moral right, wrong, and obligation) cannot be true. I then criticize a recent attempt to sustain the principle that an agent is morally blameworthy for performing an action only if this action is morally wrong. I conclude with discussing Fisher's view that even if causal determinism undermines morally deontic judgments, it still leaves room for other significant moral (...) assessments including assessments of moral blameworthiness.

The paper discusses the category of one of the most fundamental expressions of agency, those movements of agents that are actions. There have been three dominant views of action since the 1960s: 1. the Causal Theory of Action, 2. the Tryings/Willings view, and 3. Agent Causation. These views claim that actions are: 1. events of bodily movements which have the right causes; 2. specific types of mental events causing events of bodily movements; 3. instances of the causal relationship (...) between agents and events of bodily movements. Among other arguments, a specific interpretation of the difference between transitive and intransitive verbs has been taken by defenders of the Tryings/Willings views and Agent Causation to support their main claims. The paper argues that these three views mischaracterise actions of bodily movements. It argues for this by highlighting some implausible claims and problems of the three views; by offering an interpretation of the difference between transitive and intransitive verbs that does not lend support to these views; and finally, by providing an alternative view of actions. This view is the Pluralist View according to which agents’ movements are the activations of agents’ abilities to move. (shrink)

One of the claims of Type Theory with Records is that it can be used to model types learned by agents in order to classify objects and events in the world, including speech events. That is, the types can be represented by patterns of neural activation in the brain. This claim would be empty if it turns out that the types are in principle impossible to represent on a finite network of neurons. We will discuss how to (...) represent types in terms of neural events on a network and present a preliminary computational implementation that maps types to events on a network. The kind of networks we will use are closely related to the transparent neural networks discussed by Strannegård. (shrink)

Standard notions in philosophy of mind have a tendency to characterize socio-cognitive abilities as if they were unique to sophisticated human beings. However, assuming that it is likely that we are soon going to share a large part of our social lives with various kinds of artificial agents, it is important to develop a conceptual framework providing notions that are able to account for various types of social agents. Recent minimal approaches to socio-cognitive abilities such as mindreading and commitment (...) present a promising starting point from which one can expand the field of application not only to infants and non-human animals but also to artificial agents. Developing a minimal approach to the socio-cognitive ability of acting jointly, I present a foundation for future discussions about the question of how our conception of sociality can be expanded to artificial agents.

Konolige''s technical notion of belief based on deduction structures is briefly reviewed and its usefulness for the design of artificial agents with limited representational and deductive capacities is pointed out. The design of artificial agents with more sophisticated representational and deductive capacities is then taken into account. Extended representational capacities require in the first place a solution to the intensional context problems. As an alternative to Konolige''s modal first-order language, an approach based on type-free property theory is proposed. It considers (...) often neglected issues, such as the need for a more general account of thede dicto-de re distinction, and quasi-indicators. Extended deductive capacities require a subdivision of Konolige''s notion of belief into two distinct technical notions,potential anddispositional belief. The former has to do with what an artificial agent could in principle come to actively believe, given enough time and its specific logical competence; the latter with what an agent can be assumed to believe with respect to a specific goal to be fulfilled.
