Evolutionary debunking arguments aim to undercut the epistemological status of our evaluative beliefs on the basis of the genesis of our belief-forming tendencies. This paper addresses the issue whether responses to these arguments must be question-begging. It argues for a pragmatic understanding of question-beggingness, according to which whether an argument is question-begging depends on the argumentative context. After laying out the debunking argument, the paper considers a variety of responses. It asks whether metaethical responses, such as Sharon Street’s response that (...) relies on a version of antirealism, can avoid begging the question. It argues that so-called ‘third-factor’ responses, which rely on substantive evaluative views, are not question-begging in all contexts. Similarly, it argues, my own ‘quasi-tracking’ response is not question-begging in all contexts. Finally, the paper asks whether responses to the debunking argument can avoid begging the question against someone who is convinced at the outset that the argument is sound. -/- .

‘The problem with simulations is that they are doomed to succeed.’ So runs a common criticism of simulations—that they can be used to ‘prove’ anything and are thus of little or no scientific value. While this particular objection represents a minority view, especially among those who work with simulations in a scientific context, it raises a difficult question: what standards should we use to differentiate a simulation that fails from one that succeeds? In this paper we build on a structural (...) analysis of simulation developed in previous work to provide an evaluative account of the variety of ways in which simulations do fail. We expand the structural analysis in terms of the relationship between a simulation and its real-world target emphasizing the important role of aspects intended to correspond and also those specifically intended not to correspond to reality. The result is an outline both of the ways in which simulations can fail and the scientific importance of those various forms of failure. (shrink) | |
Several philosophers have argued that natural selection will favor reliable belief formation; others have been more skeptical. These traditional approaches to the evolution of rationality have been either too sketchy or else have assumed that phenotypic plasticity can be equated with having a mind. Here I develop a new model to explore the functional utility of belief and desire formation mechanisms, and defend the claim that natural selection favors reliable inference methods in a broad, but not universal, range of circumstances. | |
The proper treatment of correlation in evolutionary game theory has unexpected connections with recent philosophical discussions of the theory of rational decision. The Logic of Decision (Jeffrey 1983) provides the correct framework for correlated evolutionary game theory and a variant of "ratifiability" is the appropriate generalization of "evolutionarily stable strategy". The resulting theory unifies the treatment of correlation due to kin, population viscosity, detection, signaling, reciprocal altruism, and behavior-dependent contexts. It is shown that (1) a strictly dominated strategy may be (...) selected, and (2) under conditions of perfect correlation a strictly efficient strategy must be selected. (shrink) | |
The iterated Prisoner’s Dilemma has become the standard model for the evolution of cooperative behavior within a community of egoistic agents, frequently cited for implications in both sociology and biology. Due primarily to the work of Axelrod (1980a, 198Ob, 1984, 1985), a strategy of tit for tat (TFT) has established a reputation as being particularly robust. Nowak and Sigmund (1992) have shown, however, that in a world of stochastic error or imperfect communication, it is not TFT that finally triumphs in (...) an ecological model based on population percentages (Axelrod and Hamilton 1981), but ‘generous tit for tat’ (GTFT), which repays cooperation with a probability of cooperation approaching 1 but forgives defection with a probability of l/3. In this paper, we consider a spatialized instantiation of the stochastic Prisoner’s Dilemma, using two-dimensional cellular automata (Wolfram, 1984, 1986; Gutowitz, 1990) to model the spatial dynamics of populations of competing strategies. The surprising result is that in the spatial model it is not GIFT but still more generous strategies that are favored. The optimal strategy within this spatial ecology appears to be a form of ‘bending over backwards’, which returns cooperation for defection with a probability of 2/3 - a rate twice as generous as GTFT.

Runaway social selection resulting from partner choice may have shaped aspects of human cooperation and complex sociality that are otherwise hard to account for. Social selection is the subtype of natural selection that results from the social behaviors of other individuals. Competition to be chosen as a social partner can, like competition to be chosen as a mate, result in runaway selection that shapes extreme traits. People prefer partners who display valuable resources and bestow them selectively on close partners. The (...) resulting phenotypic covariance between displays and preferences gives fitness advantages to both, creating runaway selection that could shape a whole suite of prosocial traits including altruism, moral capacities, empathy, and theory of mind. Even though they give a net fitness benefit, traits at the endpoint of runaway social selection can have substantial deleterious effects on other traits such as viability, ability to accumulate resources, or vulnerability to mental disorders. Social selection forces arising from self-interested partner choices may be an invisible hand that shaped capacities for commitment, altruism, and other prosocial capacities of the human social brain.

In their classic analyses, Hobbes and Hume argue that offensively violating a covenant is irrational because the offense ruins one’s reputation. This paper explores conditions under which reputation alone can enforce covenants. The members of a community are modeled as interacting in a Covenant Game repeated over time. Folk theorems are presented that give conditions under which the Humean strategy of performing in covenants only with those who have never offensively violated or performed with an offensive violator characterizes an equilibrium (...) of the repeated Covenant Game. These folk theorems establish that for certain ideal settings Hobbes’ and Hume’s arguments against offensively violating covenants are compelling. However, these ideal settings presuppose that the community has certain mechanisms that generate common knowledge of the identities of those with whom one should perform. I analyze the results of computer simulations of the interactions in a community whose members must rely upon private communication alone. The computer simulation data show that in this community, reputation effects cannot effectively deter members from offensively violating covenants. I conclude that Hobbes’ and Hume’s warnings against offensive violation are compelling only on condition that the community is sufficiently structured to generate common knowledge among its members. I also conclude that even in such structured communities, the Humean strategy is not the uniquely “correct” policy. (shrink) | |
Discussions of altruism occur in three importantly different contexts. During the past four decades, evolutionary theory has been concerned with the possibility that forms of behaviour labelled as altruistic could emerge and could be maintained under natural selection. In these discussions, an agent A is said to act altruistically towards a beneficiary B when A's action promotes the expected reproductive success of B at expected reproductive cost to A. This sort of altruism, biological altruism, is quite different from the kind (...) of behaviour important to debates about ethical and social issues. There the focus is on psychological altruism, a notion that is concerned with the intentions of the agent and that need have no connection with the spread of anyone's genes. Psychological altruists are people with other-directed desires, emotions or intentions (this is a rough preliminary characterization, to be refined below). Finally, in certain kinds of social scientific research, the important concept is that of behavioural altruism. From the outside, behavioural altruists look like psychological altruists, although their motives and preferences may be very different. (shrink) | |
The authors explore the interfaces between different dimensions of moral cognition, bridging economic, Bayesian and reinforcement learning perspectives. The human aversion to harming others cuts across these different interfaces, influencing decisions, judgments, and inferences about morality. | |
A psychologically plausible analysis of the way we assign illocutionary forces to utterances is formulated using a 'contextualist' analysis of what is said. The account offered makes use of J. L. Austin's distinction between phatic acts (sentence meaning), locutionary acts (contextually determined what is said), illocutionary acts, and perolocutionary acts. In order to avoid the conflation between illocutionary and perlocutionary levels, assertive, directive and commissive illocutionary forces are defined in terms of inferential potential with respect to the common ground. Illocutionary (...) forces are conceived as automatic but optional components of the process of interpretation. (shrink) | |
Contrary to widely held assumptions, an evolutionary metaethics need not be non-cognitivist. I define evolutionary metaethics as the claim that certain phenotypic traits expressing certain genes are both necessary and sufficient for explanation of all other phenotypic traits we consider morally significant. A review of the influential cognitivist Immanuel Kants metaethics shows that much of his ethical theory is independent of the anti-naturalist metaphysics of transcendental idealism which itself is incompatible with evolutionary metaethics. By matching those independent aspects to an (...) evolutionary metaethics a cognitivist Kantian evolutionary metaethical theory is a possibility for researchers to consider. (shrink) | |
I present and defend (1) an account of ethical judgments as judgments about our reasons to feel specific motivationally laden attitudes, (2) an account of what an agent should do in terms of what would achieve ends that she has reason to be motivated to pursue, and (3) an account of an agent’s reasons for motivation (and thus action) in terms of the prescriptions of the most fundamental principles that guide her deliberations. Using these accounts, I explain the connection between (...) ethics and reasons for action, how ethical judgments are both descriptive and intrinsically motivating, and how ethical facts arise from facts about agents’ deliberations.

In this article I reevaluate Immanuel Kant's moral philosophy from a post–Darwinian perspective. Taking an evolutionary approach to human reasoning and incorporating some recent work on the science of the emotions, I argue that the Kantian bifurcation of reason and emotion, which underlies his moral philosophy, is no longer tenable. Kant's practical defense of his ethics as being the only option that can save morality from the dangers posed by naturalism is also considered and rejected. Instead, I argue that an (...) evolutionary view of reason and emotion can provide an adequate ground for morality and explore the possibility and advantages of such an ethics. (shrink) | |

La evidencia comparativa reciente sugiere que algunas especies no humanas sienten empatía hacia otros congéneres, la cual es una capacidad necesaria para la presencia y evolución de la moralidad. Por otro lado, la Hipótesis del Cerebro Social plantea relaciones entre la evolución de la neocorteza cerebral en primates y el tamaño de sus grupos sociales. Este artículo vincula estas ideas al señalar que: (i) la empatía y la moralidad son subproductos de la expansión de la neocorteza cerebral, y (ii) la (...) función de tales capacidades es facilitar la cooperación entre individuos, aumentando su cohesión social. Recent comparative evidence suggests that some nonhuman species feel empathy towards fellow group members and empathy is a necessary capacity for the presence and evolution of morality. On the other hand, the Social Brain Hypothesis suggests relationships between the evolution of brain's neocortex in primates and the size of their social groups. This paper links these ideas by suggesting that (i) empathy and morality are by-products of the expansión of brain's neocortex, and that (ii) the function of such capacities is to facilitate cooperation between individuals, increasing their social cohesion.

One reason for the widespread resistance to evolutionary accounts of the origins of humanity is the fear that they undermine morality: if morality is based on nothing more than evolved dispositions, it would be shown to be illusory, many people suspect. This view is shared by some philosophers who take their work on the evolutionary origins of morality to undermine moral realism. If they are right, we are faced with an unpalatable choice: to reject morality on scientific grounds, or to (...) reject our best- confirmed scientific explanation of our origins in order to save morality. Fortunately, as I show, we have no reason to accept the deflationary claims of some evolutionary ethicists: morality, as we ordinarily understand it, is fully compatible with evolution. (shrink) | |
Este texto tem como objetivo apresentar a principal motivação filosófica para se defender uma teoria causal da memória, que é explicar como pode um evento que se deu no passado estar relacionado a uma experiência mnêmica que se dá no presente. Para tanto, iniciaremos apresentando a noção de memória de maneira informal e geral, para depois apresentar elementos mais detalhados. Finalizamos apresentando uma teoria causal da memória que se beneficia da noção de veritação (truthmaking). | |
The study of culture and cultural selection from a biological perspective has been hampered by the lack of any firm theoretical basis for how the information for cultural traits is stored and transmitted. In addition, the study of any living system with a decentralized or multi-level information structure has been somewhat restricted due to the focus in genetics on the gene and the particular hereditary structure of multicellular organisms. Here a different perspective is used, one which regards living systems as (...) self-constructing energy users that utilize their genome as a library of information, making the genetic system just another component that adds fitness to the overall integrated unit. In this framework, basic fitness is measured as the ability to gather energy for growth and reproduction, and the fitness of the genetic system is broken down into two aspects: first, the effectiveness in searching for new somatic functional information, and second, the effectiveness in searching for better structures to store and process information. With this more generalized perspective, major evolutionary transitions to higher levels of organization become competitions between different information structures; furthermore the functioning and fitness of cultural systems can be more easily described and compared with other modes of information storage within biological systems. Modern technological societies are self-constructing systems that rely on written (symbolic) information storage and very complex algorithms that effectively search for variation with a high probability of successful selection. These systems are currently competing with traditional organic systems, and this competition constitutes the latest major evolutionary transition. Upon comparison of the energy-gathering potential of symbolic-based systems with DNA-based life, it appears that symbolic systems have a tremendous fitness potential and the current shift to a higher level of selection may be as significant and far-reaching as any of the previous major evolutionary transitions.

In ''''A Defense of Evolutionary Ethics'''' (1986), Robert J. Richardsendeavors to explain how moral ''oughts'' can be derived from thescience of evolutionary biology without committing the dreadednaturalistic fallacy. First, Richards assumes that ''ought'' as usedin ethical discourse bears the same meaning as ''ought'' used anywherein science, indicating merely that certain results or behaviors arepredicted based on prior structured contexts. To this extent, themoral behavior of animals, what they ''ought'' to do, could arguablybe predicted by evolutionary biology as effectively as, say,molecular (...) behavior may be predicted by chemistry. But afteracknowledging that biological inferences to this limited senseof ''ought'' were never contested by Moore''s naturalistic fallacy,Richard proposes to add to evolutionary ethics a decision procedureto determine which members of a set of predicted behaviors arethose which truly ought to occur – in the genuinelyprescriptive sense intended by ethical discourse. But theprocedure which Richards fabricates for this purpose appealsto such alleged ''facts'' as cultural conventions and moral opinionpolling, hardly a secure foundation for the sort of scientific ethics promised by Richards at the outset.

This monograph discusses the question of what it is to be a reason – mainly in practical ethics – and proposes an original contribution to metaethics.It critically examines theories of metaethical realism, constructivism and error theory and identifies several misunderstandings or unclarities in contemporary debates. Based on this examination, the book suggests a distinction between a conceptual question, that can be answered by pure first-personal thinking, and a material question, that targets responses to reasons as a natural phenomenon in space (...) and time and that can be answered by help of the sciences. While this book defends a sharp distinction between these approaches, it also argues that the insights gained by the distinct approaches can be fruitfully integrated into a comprehensive picture.The comprehensive picture promoted in this book, based on both philosophical analysis and resources from psychology and cognitive science, is a picture of reasons as items in a collective archive of mind – reconfiguring the “domain of reasons” as a collectively established and socially cultivated fund of considerations with normative weight. The developed Collective Archive View combines Reasons Fundamentalism as an answer to the conceptual question, with a social ontological proposal, similar to Haslanger’s critical realism, as an answer to the material question.Thereby, it introduces central ideas from the field of social metaphysics into metaethics. At the same time, it offers a way of settling some controversies within metaethics, going on between proponents of Reasons Fundamentalism and Constitutivism, realism and constructivism, as well as proponents of mind-dependence and mind-independence of normative facts. Finally, the proposal enables us to envision and conceptualize genuine normative change within a metaethical theory. (shrink) | |
My aim in this paper is to demonstrate that a very simple learning rule based on imitation can help to sustain altruism as a culturally transmitted pattern or behaviour among agents playing a standard prisoner’s dilemma game. The point of this demonstration is not to prove that imitation is single-handedly responsible for existing levels of altruism (a thesis that is false), nor is the point to show that imitation is an important factor in explanations for the evolution of altruism (a (...) thesis already prominent in the existing literature). The point is to show that imitation contributes to the evolution of altruism in a particular way that is not always fairly represented by evolutionary game theory models. Specifically, the paper uses a simple model to illustrate that cultural transmission includes mechanisms that do not transmit phenotype vertically (i.e. from parent to related offspring) and that these mechanisms can promote altruism in the absence of any direct biological propensity favouring such behaviour. This is a noteworthy result because it shows that evolutionary models can be built to explicitly reflect the contribution of non-vertical transmission in our explanations for the evolution of altruism among humans and other social species.

This essay addresses recent claims about the compatibility of the sociobiological theory of reciprocal altruism with standard Western formulations of the Golden Rule. Derek Parfit claims that the theory of reciprocal altruism teaches us to be “reciprocal altruists,” who benefit only those people from whom we can reasonably expect benefits in the future. The Golden Rule, on the other hand, teaches us to benefit anyone regardless of their intention or ability to return the favor, or as Parfit puts it, the (...) Golden Rule teaches us to be “suckers.” I argue that this distinction is founded on a misconception of the nature of the theory of reciprocal altruism, which is sociobiological as opposed to moral, and that this distinction accordingly confuses is with ought. Sociobiological theories may explain underlying psychological motivations in individuals (and perhaps even in populations), but these theories do not prescribe any sort of moral behavior. Furthermore, the theory of reciprocal altruism does not imply mental states of which agents are aware. The unconscious motivations assumed by this theory are in fact compatible with certain formulations of the Golden Rule; I will accordingly argue for the view that certain words with moral content related to the Golden Rule—such as “altruism” and “selfishness”—exist only insofar as they are social tools, which can further the self-interests of an individual in any group.

Over the past decade, New Atheists have campaigned against the influence of religion in public life and favored a more enlightened understanding of the world ? one based on the methods and theories of the natural sciences. Although the leaders of this movement refuse to give religion, even moderate religion, any place in determining moral conduct, they offer few alternatives. Most define moral responsibility by referring to facts about human biology or natural moral intuitions, yet without adequately defending this or (...) exploring the possibilities of non-naturalistic secular moralities. This essay argues that New Atheists' moral theories tend to be weak because of their naturalist assumptions. Its leading proponents seem to be unwilling to acknowledge that moral philosophy can play a role in developing secular moral precepts because philosophy fails to meet their strong criteria of scientific validity. This position is misguided not only because it has led New Atheists to defend weak moral theories but also because the methods of inquiry used in moral philosophy make it distinct from faith for many of the same reasons that the New Atheists think that science is distinct from faith.

The paper provides an account of the pragmatist philosophical conception of reciprocity and altruism based on the ontology of “panrelationalism”. The Deweyan concepts of transaction and cooperation are also outlined in some detail as well as the pragmatist (Rortyan) idea of justice. The author attempts to show that altruism is not necessarily just reciprocal but demands as its supplement (at least) altruism without reciprocation. | |
The shortage conditions created by the COVID-19 pandemic have been changing our ordinary way of life around the world since the beginning of 2020. Such conditions pose a challenge for shaping a cohesive theory of justice—one that takes non-ideal circumstances as necessary for the model. These conditions also interfere with agents’ moral capacity in ways that make it difficult for them to tell what is morally relevant, which impairs their ability to identify what actions are just. To shed light on (...) these problems, I turn to David Hume’s theory of justice as a test case to portray how outer conditions shape an agent’s inner conditions and affect the foundation of our moral perception of what is just.

In this dissertation I defend five claims about trust: 1) trusting and trustworthiness are conceptually but not causally connected; 2) trust is risky; 3) trust requires good will; 4) trust is a two-part relation; and 5) trust is an interpretative framework. A concern for trust often appears in discussions about testimony and the expectation of truthfulness; Bentley Glass, John Hardwig, and Jonathan Adler each address the role of trust in science while assuming a necessary connection between trusting and trustworthiness. I (...) argue that this conception is untenable because a justification for one fails to suffice as a justification of the other. I show, instead, that it is our assessment that links trustworthiness to trusting. My second claim, that trust involves risk, is contentious. I argue that the common understanding of risk as harm, which is held by Russell Hardin, contains the more technical understanding of risk as uncertainty, which is suggested by Niklas Luhman. Trust is risky precisely because it is inherently uncertain. Annette Baier argues that failing to recognize a distinction between trusting and action associated with that trust leads us to accept accounts of trust that are too broad. I argue that trust is to believe that another is concerned with your well-being, has good will, because she is concerned about you and not that it will necessarily benefit her in some way. Seeing trust as good will allows me to advance my fourth claim, that trust is a two-part relation, because trust is the assessment of another's good will towards me. Trusting another is believing that the other's good judgment will include concern and consideration for my interests because they are my interests. My fifth point follows naturally once trust is understood to be a risky, two-part relation requiring good will: it is an interpretive framework. Our trust in another sets the tone for understanding her behavior such that we take her actions as either supporting or blocking our interests. This account takes the capacity to trust to be the foundation for, rather than merely an outgrowth of, our judgments. (shrink) | |
The term “altruism” is used in many ways. In this thesis, I discuss altruism as a motivation, which is an influential notion in philosophy and the social sciences. Questions about the nature and the possibility of altruistic motivation have inspired much debate, both in academia and in everyday conversations. How can we know when we are truly altruistic and when we are merely helping others as a means to some egoistic goal? Are humans even capable of genuine altruistic motivation or (...) are we always egoistic deep down? Before answering questions like these, however, we need to ask a more fundamental question: how should we define altruistic motivation? The standard account of altruistic motivation in the literature defines it as an ultimate desire to increase the welfare of others. The central claim I will argue for in this thesis is that this standard account is intrinsically flawed and should be abandoned. -/- The problem with the standard account of altruistic motivation, in short, is its reliance on the notion of “ultimate desire”, which is a limited and unfruitful way of conceptualizing altruistic motivation. The criticism I propose is based on an interdisciplinary analysis of many aspects of the standard account, discussing its philosophical basis, its use in scientific research, its historical development, and its relation to common sense and morality. -/- This thesis is divided into four parts, each composed of two chapters. Part I presents the many technical accounts of altruism present in the scientific literature, distinguishing the standard account of altruistic motivation from alternative accounts of altruism. I discuss the hypotheses of psychological altruism, which states that some of our ultimate desires aim to increase the welfare of others, and psychological egoism, which states that all of our ultimate desires are egoistic. In this first part, I discuss some of the central philosophical concepts underlying the standard account of altruistic motivation, showing their implications for the debate about psychological altruism. -/- Part II discusses the main arguments for the existence of altruistic motivation. I argue that the main arguments in the scientific literature fail in making a defense of psychological altruism and that the definition of altruistic motivation makes the solution to the debate on psychological altruism virtually impossible. I conclude that the standard account makes altruistic motivation an unverifiable and unfruitful notion for scientific research. -/- Part III discusses the history of altruism and egoism, focusing particularly on early modern philosophy. I argue that the modern accounts of altruism and egoism diverge from the contemporary standard account of altruistic motivation. Reading the debates in modern philosophy through the lens of psychological altruism and psychological egoism oversimplifies and impoverishes the modern debate. I argue that the standard account also fails in representing the original use of “altruism”, proposed by Auguste Comte. In this third part, I show how the use of the standard account of altruistic motivation cannot be based on its historical foundations. -/- Finally, Part IV addresses the normative character of altruism and discusses some alternative ways of conceptualizing altruism. I argue that the standard account of altruistic motivation does not reflect the ordinary use of the term “altruism” and fails in accounting for its normative character. As an alternative, I propose an alternative account of altruism, virtue altruism. I claim that this account better reflects the ordinary intuitions about altruism, accommodates the descriptive and normative dimensions of altruism, is at home with most of the historical accounts of altruism, and may promote the active promotion of altruistic actions.
