Natural Justice is a bold attempt to lay the foundations for a genuine science of morals using the theory of games. Since human morality is no less a product of evolution than any other human characteristic, the book takes the view that we need to explore its origins in the food-sharing social contracts of our prehuman ancestors. It is argued that the deep structure of our current fairness norms continues to reflect the logic of these primeval social contracts, but the (...) particular fairness norm a society operates is largely a product of cultural evolution. In pursuing this point, the book proposes a naturalistic reinterpretation of John Rawls' original position that reconciles his egalitarian theory of justice with John Harsanyi's utilitarian theory by identifying the environment appropriate to each.

Game theory has proved a useful tool in the study of simple economic models. However, numerous foundational issues remain unresolved. The situation is particularly confusing in respect of the non-cooperative analysis of games with some dynamic structure in which the choice of one move or another during the play of the game may convey valuable information to the other players. Without pausing for breath, it is easy to name at least 10 rival equilibrium notions for which a serious case can (...) be made that here is the “right” solution concept for such games. (shrink)

If some external enforcement agency compels us to honor deals reached in the original position, then Harsanyi has shown that the outcome will be utilitarian. Under the same hypotheses, Rawls claims that the outcome will be egalitarian. This chapter confirms that Harsanyi is correct. It goes on to use the concept of an empathy equilibrium to predict the standard of interpersonal comparison needed to operate a utilitarian norm that will evolve in the medium run.

Wilber's groundbreaking synthesis of religion, philosophy, physics, and psychology started a revolution in transpersonal psychology.

In Gemes (1990) I examined certain formal versions of hypothetico-deductivism (H-D) showing that they have the unacceptable consequence that "Abe is a white raven" confirms "All ravens are black"! In Gemes (1992) I developed a new notion of content that could save H-D from this bizarre consequence. In this paper, I argue that more traditional formulations of H-D also need recourse to this new notion of content. I present a new account of the vexing notion of the natural axiomatization of (...) a theory. The notion is used to construct a form of H-D that allows for the type of selective confirmation without which Glymour (1980a,b) claims H-D is hopeless. (shrink)

It's hard to say exactly when modern science began. Many scholars would date it at roughly 1600, when both Kepler and Galileo started using precision measurement to map the universe. But one thing is certain: starting from whatever date we choose, modern science was, in many important ways and right from the start, deeply antagonistic to established religion.

Some behavioral economists argue that the honoring of social norms can be adequately modeled as the optimization of social utility functions in which the welfare of others appears as an explicit argument. This paper suggests that the large experimental claims made for social utility functions are premature at best, and that social norms are better studied as equilibrium selection devices that evolved for use in games that are seldom studied in economics laboratories.

This is the second part of a two-part paper. It can be read independently of the first part provided that the reader is prepared to go along with the unorthodox views on game theory which were advanced in Part I and are summarized below. The body of the paper is an attempt to study some of the positive implications of such a viewpoint. This requires an exploration of what is involved in modeling “rational players” as computing machines.

Wilber's groundbreaking synthesis of religion, philosophy, physics, and psychology started a revolution in transpersonal psychology. He was the first to suggest in a systematic way that the great psychological systems of the West could be integrated with the noble contemplative traditions of the East. Spectrum of Consciousness, first released by Quest in 1977, has been the prominent reference point for all subsequent attempts at integrating psychology and spirituality.

This article is extracted from a forthcoming book, ‘Natural Justice’. It is a nontechnical introduction to the part of game theory immediately relevant to social contract theory. The latter part of the article reviews how concepts such as trust, responsibility, and authority can be seen as emergent phenomena in models that take formal account only of equilibria in indefinitely repeated games. Key Words: game theory • equilibrium • evolutionary stability • reciprocity • folk theorem • trust • altruism • responsibility (...) • authority. (shrink)

Although far from unanimous, there seems to be a general consensus that neither mind nor brain can be reduced without remainder to the other. This essay argues that indeed both mind and brain need to be included in a nonreductionistic way in any genuinely integral theory of consciousness. In order to facilitate such integration, this essay presents the results of an extensive cross-cultural literature search on the ‘mind’ side of the equation, suggesting that the mental phenomena that need to be (...) considered in any integral theory include developmental levels or waves of consciousness, developmental lines or streams of consciousness, states of consciousness, and the self . A ‘master template’ of these various phenomena, culled from over one-hundred psychological systems East and West, is presented. It is suggested that this master template represents a general summary of the ‘mind’ side of the brain-mind integration. The essay concludes with reflections on the ‘hard problem', or how the mind-side can be integrated with the brain-side to result a more integral theory of consciousness. (shrink)

This paper argues that we need to look beyond Bayesian decision theory for an answer to the general problem of making rational decisions under uncertainty. The view that Bayesian decision theory is only genuinely valid in a small world was asserted very firmly by Leonard Savage [18] when laying down the principles of the theory in his path-breaking Foundations of Statistics. He makes the distinction between small and large worlds in a folksy way by quoting the proverbs ”Look before you (...) leap” and ”Cross that bridge when you come to it”. You are in a small world if it is feasible always to look before you leap. You are in a large world if there are some bridges that you cannot cross before you come to them. As Savage comments, when proverbs conflict, it is proverbially true that there is some truth in both—that they apply in different contexts. He then argues that some decision situations are best modeled in terms of a small world, but others are not. He explicitly rejects the idea that all worlds can be treated as small as both ”ridiculous” and ”preposterous”. The first half of his book is then devoted to a very successful development of the set of ideas now known as Bayesian decision theory for use in small worlds. The second half of the book is an attempt to develop a quite different set of ideas for use in large worlds, but this part of the book is usually said to be a failure by those who are aware of its existence.2 Frank Knight [15] draws a similar distinction between making decision under risk or uncertainty.3 The pioneering work of Gilboa and Schmeidler [7] on making..

Biological understanding of human cognitive functions is incomplete because of failure to understand the evolution of complex functions and organisms in general. Here, that failure is attributed to an aspect of the standard neo-Darwinian synthesis, namely commitment to evolution by natural selection of genetic programs in stable environments, a position that cannot easily explain the evolution of complexity. When we turn to consider more realistic, highly changeable environments, however, another possibility becomes clearer. An alternative to genetic programs—dubbed “biogrammars”—is proposed here (...) to deal with complex, changing environments and explain evolving complexity from pre-genetic life to human socio-cognitive functions.

This paper argues that Nietzsche is deliberately imprecise in his characterization of what he calls the slave revolt in morality. In particular, none of the people or groups he nominates as instigators of the slave revolt, namely, Jewish priests, the Jewish people, the prophets, Jesus, and Paul, were literally slaves. Analysis of Nietzsche's texts, including his usage of the term “slaves,” and his sources concerning those he nominates as the instigators of the slave revolt, make clear that Nietzsche knew none (...) of these were literally slaves. He calls it a slave revolt because he means that the propagators of that revolt preached what he takes to be the slavish values, including, humility, compassion, obedience, and lack of egoism. He uses the high loaded term “slave” both to disparage those values and, most importantly, to bring home to his readers the message that they, as inheritors of Judeo‐Christian values, actual adhere to and practice the debased slavish values preached, but not necessarily practiced, by the original instigators of the slave revolt. For Nietzsche, his readers are strangers to themselves, thus he notes “slavery is everywhere visible, although it does not call itself as such.”. (shrink)

My answer to the question why? is relatively uncontroversial among anthropologists. Sharing food makes good evolutionary sense, because animals who share food thereby insure themselves against hunger. It is for this reason that sharing food is thought to be so common in the natural world. The vampire bat is a particularly exotic example of a food-sharing species. The bats roost in caves in large numbers during the day. At night, they forage for prey, from whom they suck blood if they (...) can, but they aren’t always successful. If they fail to obtain blood for several successive nights, they die. The evolutionary pressure to share blood is therefore strong. The biologist Wilkinson [59] reports that a hungry bat begs for blood from a roostmate, who will sometimes respond by regurgitating some of the blood it is carrying in its own stomach. This isn’t too surprising when the roostmates are related, but the bats also share blood with roostmates who aren’t relatives. The behaviour is nevertheless evolutionarily stable, because the sharing is done on a reciprocal basis, which means that a bat is much more likely to help out a roostmate that has helped it out in the past. Bats that refuse to help out their fellows therefore risk not being helped out themselves in the future. Vampire bats have their own way of sharing, and we have ours. We call our way of sharing “fairness”. If the accidents of our evolutionary history had led to our sharing in some other way, it would not occur to us to attribute some special role to our current fairness norms. Whatever alternative norms we then.. (shrink)

Playing for Real is a problem-based textbook on game theory that has been widely used at both the undergraduate and graduate levels. This Coursepack Edition will be particularly useful for teachers new to the subject. It contains only the material necessary for a course of ten, two-hour lectures plus problem classes and comes with a disk of teaching aids including pdf files of the author's own lecture presentations together with two series of weekly exercise sets with answers and two sample (...) final exams with answers. There are at least three questions a game theory book might answer: What is game theory about? How is game theory applied? Why is game theory right? Playing for Real is perhaps the only book that attempts to answer all three questions without getting heavily mathematical. Its many problems and examples are an integral part of its approach. Just as athletes take pleasure in training their bodies, there is much satisfaction to be found in training one's mind to think in a way that is simultaneously rational and creative. With all of its puzzles and paradoxes, game theory provides a magnificent mental gymnasium for this purpose. It is the author's hope that exercising on the equipment provided by this Coursepack Edition will bring the reader the same kind of pleasure that it has brought to so many other students. (shrink)

This volume looks outward to the twenty-first century and to the dynamics of this first truly global age. It asks the fundamental question: how might human societies live? In contrast to the orthodoxies of academic Philosophy and International Relations in much of the twentieth century, which marginalised or rejected the study of ethics, the contributors here believe that there is nothing more political than ethics, and therefore deserving of scholarly analysis. By exploring some of the oldest questions about duties and (...) obligations within and beyond humanly constructed boundaries, the essays help us ponder the most profound question in world politics today: who will the twenty-first century be for?

My article concerns constitutional interpretation and substantive due process, issues that played a central role in Obergefell v. Hodges (2015), one of the two same-sex marriage cases. (The other same-sex marriage case was United States v. Windsor (2013).) -/- The late Justice Scalia consistently maintained that the Court “invented” substantive due process and continues to apply this legal “fiction” not because the Constitution supports it but simply because the justices like it. Two theories underlay his cynical conclusion. First is the (...) theory of “Constitutional Textualism”—or just plain “Textualism”—which says that the meaning of the Constitution lies entirely within the “four corners” of the document. Second is the theory of “Originalism,” which says that this meaning was fixed at the time of ratification. (Likewise, the meanings of the amendments were fixed at the time of their ratification.) -/- While Justice Scalia helped to inspire a Textualist/Originalist (and anti-substantive-due-process) movement, his Originalism has received far more attention than his Textualism. Since Judge Robert Bork first introduced Originalism to the general public during his Supreme Court nomination hearings in 1987, this theory has ignited passions on all sides and effectively re-framed the entire debate about how to interpret the Constitution. Constitutional scholars, left and right, now define themselves as either for or against Originalism. Meanwhile, Textualism has merely retreated into the background. -/- Part of the reason for this disparate treatment is that many who reject Originalism still consider themselves to be Textualists. They agree with Justice Scalia (and Judge Bork) that the text is all-important. They disagree, however, that its meaning was fixed for eternity at ratification. Instead, they maintain that either the meaning of the text or applications of this meaning to new cases can change as society changes. -/- In this Article, I bring Textualism out of Originalism’s shadow and into broad daylight. I argue that once we dig just a little deeper into the proposition that all of the meaning in the Constitution inheres in its words, we find that this theory simply cannot work. In order to interpret the nation’s foundational document, we must resort to assumptions that it does not explicitly state. (Indeed, even Textualism itself is a theory that the Constitution does not explicitly endorse.) And the notion that “extra-textual” assumptions necessarily inform our interpretations of the Constitution poses a direct and insurmountable threat to Textualism. -/- The Constitution actually requires each judge, when faced with a case concerning the right to privacy, not merely to consider the text but also to anticipate and evaluate the moral, social, and political consequences of both possible decisions before choosing between them. While this position may initially sound counterintuitive, it turns out to be a much more realistic theory of constitutional interpretation than Textualism (and Originalism). -/- I ultimately conclude that, contrary to Justice Scalia, the Constitution most certainly does protect a right to privacy. For what it’s worth, the Obergefell majority agree with me (and oppose Justice Scalia). I aim to show exactly why they are correct. (shrink)

In this paper, I argue that accounts of the normative basis of morality face the following puzzle, drawing on a case found in Susan Wolf’s influential discussion of conflicts between the moral and personal points of view. On the one hand, morality appears to constitute an independent point of view that can intelligibly conflict with, and can conceivably be overruled by, the verdicts of other points of view. On the other hand, moral demands appear to carry a distinctive sort of (...) authority; moral reasons normally seem to take priority over other kinds of considerations, and the verdicts of morality seem to possess a distinctive place in our deliberations, in that they appear to represent standards that we are open to legitimate complaint for failing to honor. After clarifying the nature of the problem, I argue that a contractualist theory of morality can resolve the puzzle by offering a compelling vindication of the independence of the moral perspective, the normal priority of moral reasons, and the deliberative significance of moral verdicts, within a unified theoretical framework. Furthermore, I claim that this contractualist analysis can help account for the sense of deep conflict that is characteristic of the sort of troubling moral choices that Wolf calls to our attention.

Moral contractualism holds that addressing our minds to the morality of right and wrong involves identifying principles for the mutual regulation of behavior that could be the object of reasonable agreement among persons if they were appropriately motivated and fully informed. A common criticism of the theory is that the test of reasonable agreement it endorses is indeterminate. To be more specific, it is claimed that the notion of reasonableness is too vague or ill-defined to be of use in guiding (...) our decisions in situations where it is necessary to balance the complaints of different people against each other, so that we may derive an all things considered conclusion regarding what we ought, morally, to do. In this article, I propose a novel interpretation of the contractualist method of reasoning that overcomes the indeterminacy objection, building on a broadly Aristotelian conception of practical deliberation about ends. I demonstrate that this criticism is based on a misunderstanding of the nature of contractualist moral reasoning. The key is to recognize that deliberation about what others could not reasonably reject is not a matter of applying a fixed criterion of reasonableness in order to arbitrate conflicts between the interests of different individuals, as it is commonly assumed. Rather, it is a process in which the ideal of justifiability to others and people’s moral claims are specified together through holistic deliberation. The goal of this process is to construct a coherent conception of both our particular moral claims and the general aim of reasonable agreement that is reasonably acceptable to each person. On this view, contrary to what critics assert, the contractualist method of reasoning, properly understood, will almost always have a determinate answer. (shrink)

In his paper "Why a Class Can't Change Its Members," Richard Sharvy appears to establish the impossibility of the existence of a variable class—that is, a class that at one time has a member that is not a member of it at another time. I first indicate the importance of Sharvy's argument for our understanding of the concept of identity in the contexts of time and modality, and I summarize his argument. Sharvy says that a class C that has one (...) (non-variable) group of members at t2 and another (nonvariable) group of members at t2 would be identical with both the class C1 that always has the first group as members and the class C2 that always has the second group as members. This is an impossibility, since in general, one thing cannot be identical with two.I then criticize Sharvy's argument by pointing out a weakness in the defense of the claim that C = C1 and C = C2. This weakness is due to an ambiguity in Sharvy's Principle of Extensionality. (shrink)

The ambiguity aversion reported in experiments on the Ellsberg paradox is then explained by assigning a larger weight to the lower probability of winning than to the upper probability. However, arguments are given here that would make anything but equal weights irrational when using the Hurwicz criterion. The paper continues by embedding the Hurwicz criterion in an extension of expected utility theory that we call expectant utility. (shrink)

This commentary emphasizes two problem areas mentioned by Burt. First, that within-family designs do not eradicate stratification confounds. Second, that the linear/additive model of genetic causes of form and variation is not supported by recent progress in molecular biology. It concludes with an appeal for a (biologically and psychologically) more realistic model of such causes.

Advances in machine learning and the development of very large knowledge graphs have accompanied a proliferation of ontologies of many types and for many purposes. These ontologies are commonly developed independently, and as a result, it can be difficult to communicate about and between them. To address this difficulty of communication, ontologies and the communities they serve must agree on how their respective terminologies and formalizations relate to each other. The process of coming into accord and agreement is called “harmonization.” (...) The Ontology Summit 2021 examined the overall landscape of ontologies, the many kinds of ontology generation and harmonization, as well as the sustainability of ontologies. The Communiqué synthesizes and summarizes the findings of the summit as well as earlier summits on related issues. One of the major impediments to harmonization is the relatively poor quality of natural language definitions in many ontologies. The summit surveyed the state of the art in natural language definition development, based on lexicographic principles, as well as examples of ongoing projects that are explicitly dealing with harmonization and sustainability.

This chapter looks to the broad consequences of the theory of fairness advanced in this book to questions of social reform. The traditional spectrum of political attitudes that ranges from the utilitarian left to the libertarian right is rejected in favor of a more realistic opposition between the neofeudal societies in which we currently live, and the prospect of fairer and freer societies that could be created by a planned program of decentralization which is identified with the whiggery that inspired (...) the Glorious Revolution of 1688 and the Declaration of Independence of 1776. The contribution that game theory can make to such a program is briefly reviewed along with the deficiencies of the current theory. (shrink)

The folk theorem shows that cooperative behavior can be sustained as a Nash equilibrium in indefinitely repeated games — a phenomenon known as reciprocal altruism. The same theorem offers a solution to various other social mysteries. Who guards the guardians? How are authority, blame, courtesy, dignity, envy, friendship, guilt, honor, integrity, justice, loyalty, modesty, ownership, pride, reputation, status, trust, virtue, and the like to be explained as emergent phenomena? How do beliefs that many people privately know to be false survive?

The realist belief in the primacy of the world and its underlying structure answers the question ‘why is there something rather than nothing.’ The world, and all things contained in it exists because of God’s creative act. Personal death in Christian philosophy continues the gift of human existence by shifting that temporal existence into eternal life. The death and resurrection of Christ lays the foundation for the possibility of eternal life, while the will of God provides an answer to the (...) why of human existence. The aim of this paper is to examine the effects of the death and resurrection of Christ on the metaphysical strings of human existence. The phenomenon of human death takes place on the arms of consciousness and being’s unconcealment. The subjective correlate of human death is the irreversible loss of consciousness, while the objective correlate of human death presents as the infolding of the gift of existence, namely, of being’s unconcealment from consciousness. These correlates function as a dynamic unit to explain human death and resurrection. The attempt to justify a belief in the existence of life after death from the point of view of consciousness alone is dualistic and leads to several absurdities and confusions about the nature of the afterlife state. The explanation of the resurrection of Christ as a continuation of the dialogue between being and consciousness begun on earth avoids those absurdities while maintaining personal identity. (shrink)

Environmental ethics arises as the output of a trade-off between our rights and nature's right to life. This negotiation secures the possibility of achieving sustainable developments, if it is conducted fairly. The rights of persons are delimited by their origin, as are the rights of the other. A person is the output of relationships taking place at three levels: (1) a material self; (2) a social self; and (3) a private or internal self. Pollution and war serve as an epitaph (...) to remind us of failed ethical trade-offs in these associations. (shrink)
