In this paper we review the factors alleged to be responsible for the creation of inaccurate reports among preschool-aged children, focusing on so-called "source misattribution errors." We present the first round of results from an ongoing program of research that suggests that source misattributions could be a powerful mechanism underlying children′s false beliefs about having experienced fictitious events. Preliminary findings from this program of research indicate that all children of all ages are equally susceptible to making source misattributions. Data from (...) a follow-up wave of data indicate that very young children may be disproportionately vulnerable to these kinds of errors when the procedure is changed slightly to create mental images more easily. This vulnerability leads younger preschoolers, on occasion, to claim that they actually experienced events that they only thought about. These preliminary findings are discussed in the context of the ongoing debate over the veracity and durability of delayed reports of early memories, repressed memories, dissociative states, and the validity risks posed by therapeutic techniques that entail repeated visually guided imagery inductions.

In two books and several articles Philip Goff has developed a panpsychist theory. Recently, he has put forth a version which he calls cosmopsychism. Rejecting both perfect being theism and physicalism, according to cosmopsychism, there is a unitary mind that is not only the cause of the universe, but in a sense is the universe. In this essay I critique Goff’s theory, arguing that it is not simpler than PBT, and that it fails to make important issues clear. I conclude (...) that Goff’s theory is a version of theism but fails to be a plausible alternative to PBT. (shrink)

There has been much discussion of the relationship between God and abstract objects. Three positions taken by theists are Absolute Creationism, Theistic Conceptualism, and Antirealism. I argue that Theistic Conceptualism combined with Perfect Being theology can avoid common criticisms, and that it renders the created abstract objects of Absolute Creationism unnecessary. I also hold that Antirealism is quite close to Theistic Conceptualism, and that Antirealism when combined with God as an omniscient being ends up being almost indistinguishable from it.

In his book Why There Is Something Rather Than Nothing, Bede Rundle argues that there is no need to appeal to God for an explanation concerning why the universe exists, and remains in existence. I argue that on the contrary, Rundle’s philosophical naturalism is unable to give a plausible account for the continued existence of the universe in a lawful manner and the objects of which it is composed. The major reason for this inability is that since, as Rundle admits, (...) everything that exists has a logically contingent existence, there can be no necessary principle by which contingent objects are sustained in existence.

Theism and naturalism are rival worldviews. Both seek to explain the nature of reality, but often give radically different explanations. One of the most important areas of conflict is the differing accounts for the existence of the world in which we live. Why is the actual world the one that has been instantiated instead of any other of the apparently infinite number of other possible worlds? In this paper I argue that whereas theism has a puzzle as to why God (...) actualized this particular world, naturalism has a major problem as why any ordered world exists. (shrink)

As every philosopher knows, “the design argument” concludes that God exists from premisses that cite the adaptive complexity of organisms or the lawfulness and orderliness of the whole universe. Since 1859, it has formed the intellectual heart of creationist opposition to the Darwinian hypothesis that organisms evolved their adaptive features by the mindless process of natural selection. Although the design argument developed as a defense of theism, the logic of the argument in fact encompasses a larger set of issues. William (...) Paley saw clearly that we sometimes have an excellent reason to postulate the existence of an intelligent designer. If we find a watch on the heath, we reasonably infer that it was produced by an intelligent watchmaker. This design argument makes perfect sense. Why is it any different to claim that the eye was produced by an intelligent designer? Both critics and defenders of the design argument need to understand what the ground rules are for inferring that an intelligent designer is the unseen cause of an observed effect. (shrink)

The SSIS SEL Brief Scales are multi-informant measures that were developed to efficiently assess the SEL competencies of school-age youth in the United States. Recently, the SSIS SELb was translated into multiple languages for use in a multi-site study across six European countries. The purpose of the current study was to examine concurrent and predictive evidence for the SEL Composite scores from the translated versions of the SSIS SELb Scales. Results indicated that SSIS SELb Composite scores demonstrated expected positive concurrent (...) and predictive relationships with scores from the Connor-Davidson Resilience Scale and negative relationships with scores from the problem behavior scales of the Strengths and Difficulties Questionnaire. Although there were a few exceptions, these patterns generally were consistent across informants and samples providing initial validity evidence for the Composite score from the translated versions of the SSIS SELb Scales. Limitations and future research directions are discussed. (shrink)

Freemasonry was the most widespread form of secular association in eighteenth-century England, providing a model for other forms of urban sociability and a stimulus to music and the arts. Many members of the Royal Society and the Society of Antiquaries, for instance, were Freemasons, while historians such as Margaret Jacob have argued that Freemasonry was inspired by Whig Newtonianism and played an important role in European Enlightenment scientific education. This paper illustrates the importance of natural philosophy in Masonic rhetoric and (...) utilizes material from Masonic histories, lodge records and secondary works to demonstrate that scientific lectures were indeed given in some lodges. It contends, however, that there were other sources of inspiration for Freemasonry besides Newtonianism, such as antiquarianism, and that many other factors as well as the prevalence of Masonic lodges determined the geography of English scientific culture. Although the subject of Freemasonry and natural philosophy has great potential, as Jacob has demonstrated so well, much further work, especially in the form of prosopographical studies of provincial lodges, is required before the nature of the relationship between the two can be fully appreciated.

Conway Morris argues against Stephen Jay Gould's argument that the history of life is radically contingent by describing the abundance of convergences, wherein different lineages starting in different states, arrive at the same adaptations. A standard example is the evolution of the camera eye. This review assesses the validity of Conway Morris' argument.

In this paper we compare two theories about the cognitive architecture underlying morality. One theory, proposed by Sripada and Stich (forthcoming), posits an interlocking set of innate mechanisms that internalize moral norms from the surrounding community and generate intrinsic motivation to comply with these norms and to punish violators. The other theory, which we call the M/C model was suggested by the widely discussed and influential work of Elliott Turiel, Larry Nucci and others on the “moral/conventional task”. This theory (...) posits two distinct mental domains, the moral and the conventional, each of which gives rise to a characteristic suite of judgments about rules in that domain and about transgressions of those rules. We give an overview of both theories and of the data each was designed to explain. We go on to consider a growing body of evidence that suggests the M/C model is mistaken. That same evidence, however, is consistent with the Sripada and Stich theory. Thus, we conclude that the M/C model does not pose a serious challenge for the Sripada and Stich theory. (shrink)

In Ayn Rand's philosophical perspective, and in the working epistemology of science, claims, about which there is no knowledge originating in the evidence of the senses, are considered— in the words of physicist Wolfgang Pauli—" not even false." Theistic arguments presented in Tie Journal of Ayn Rand Studies by Parrish and Toner are in this category. Various claims to which Parrish and Toner refer are shown to come from misuse of intution, middle-school fallacies about probability, and attempts to (...) deduce the existence of a god from temporary gaps in scientific knowledge.

This is response to Stephen Parrish’s article "Theodore Drange on the Fine-Tuning Argument: A Critique," ’Philosophia Christi’, Series 2, 1 (No. 2, 1999), which attacked a section of my book ’Nonbelief and Evil: Two Arguments for God’s Nonexistence’ (Amherst, NY: Prometheus Books, 1998). The Fine-Tuning Argument (FTA) maintains that the physical constants of our universe exhibit evidence of "fine-tuning" by an intelligent designer. In opposition, I suggest alternate explanations which are at least as good. Here I defend my (...) objections to FTA against Parrish’s critique, aiming to show that his defense of the argument is a failure. (shrink)

This first complete study of Marsilio Ficino’s _Commentary on Plotinus_, published in 1492, will serve as the definitive analysis of Ficino’s late philosophy and also as an essential companion to Gersh’s edition-translation of the same work.

Scientists know that human activities, primarily fossil fuel combustion, are causing Earth’s temperature to increase. Yet in 2021, only 60% of the US population understood that human activities are the primary cause of global warming. We experimentally test whether information about the human causes of global warming influences Americans’ beliefs and concerns about global warming and support for climate policies. We find that communicating information about the human-causes of global warming increases public understanding that global warming is human-caused. This information, (...) both alone and with additional information about climate impacts and policy solutions, also increases public concern about global warming and support for climate policies, although the effects on climate concern and policy support are smaller. Importantly, the treatment effects are consistent across political party, with no backlash effects among Republicans. This suggests that when informed about climate change causes, impacts and solutions, most Americans can update their own climate change beliefs, risk perceptions, and policy support. (shrink)

Recent psychology research has established that people do not employ a simple unidimensional scale for attributions of personhood, increasing from non-sentient rocks to mentally complex humans. Rather, there are two personhood dimensions: agency (e.g. planning, deciding, acting) and experience (e.g. feeling, desiring, experiencing). Here we show that this subtle distinction also occurs in the semantic space of natural language. We develop computational-linguistics tools for measuring variation in agency and experience in language and validate the measures against human judgments. To demonstrate (...) the usefulness of the method, we map both dimensions of personhood in historical English-language corpora over the last 200 years. First, we show that while women are now perceived as having similar levels of agency as men, they are still perceived as more patient-like. Second, we show that domesticated animals have gradually gained higher attributions of experience, but not agency, over time. -/- . (shrink)

Many philosophers are attracted to a complaints-based theory of the procreation asymmetry, according to which creating a person with a bad life is wrong (all else equal) because that person can complain about your act, whereas declining to create a person who would have a good life is not wrong (all else equal) because that person never exists and so cannot complain about your act. In this paper, I present two problems for such theories: the problem of impairable-life acceptance and (...) an especially acute version of the problem of improvable-life avoidance. I explain how these problems afflict two recent complaints-based theories of the procreation asymmetry, from Joe Horton and Abelard Podgorski. (shrink)

Common wisdom holds that communication is impossible when messages are costless and communicators have totally opposed interests. This article demonstrates that such wisdom is false. Non-convergent dynamics can sustain partial information transfer even in a zero-sum signalling game. In particular, I investigate a signalling game in which messages are free, the state-act payoffs resemble rock–paper–scissors, and senders and receivers adjust their strategies according to the replicator dynamic. This system exhibits Hamiltonian chaos and trajectories do not converge to equilibria. This persistent (...) out-of-equilibrium behaviour results in messages that do not perfectly reveal the sender's private information, but do transfer information as quantified by the Kullback–Leibler divergence. This finding shows that adaptive dynamics can enable information transmission even though messages at equilibria are meaningless. This suggests a new explanation for the evolution or spontaneous emergence of meaning: non-convergent adaptive dynamics. (shrink)

How does the complex nature of ecological systems affect ecologists' ability to study them? This Element argues that ecological systems are complex in a rather special way: they are causally heterogeneous. The author presents an updated philosophical account with an optimistic outlook of the methods and status of ecological research.

According to Critical-Level Views in population axiology, an extra life improves a population only if that life’s welfare exceeds some fixed ‘critical level.’ An extra life at the critical level leaves the new population equally good as the original. According to Critical-Range Views, an extra life improves a population only if that life’s welfare exceeds some fixed ‘critical range.’ An extra life within the critical range leaves the new population incommensurable with the original. -/- In this paper, I sharpen some (...) old objections to these views and offer some new ones. Critical-Level Views cannot avoid certain Repugnant and Sadistic Conclusions. Critical-Range Views imply that lives featuring no good or bad components whatsoever can nevertheless swallow up and neutralise goodness or badness. Both classes of view entail that certain small changes in welfare correspond to worryingly large differences in contributive value. -/- I then offer a view that retains much of the appeal of Critical-Level and Critical-Range Views while avoiding the above pitfalls. On the Imprecise Exchange Rates View, the quantity of some good required to outweigh a given unit of some bad is imprecise. This imprecision is the source of incommensurability between lives and populations. (shrink)

Lexical views in population axiology can avoid the Repugnant Conclusion without violating Transitivity or Separability. However, they imply a dilemma: either some good life is better than any number of slightly worse lives, or else the ‘at least as good as’ relation on populations is radically incomplete. In this paper, I argue that Archimedean views face an analogous dilemma. I thus conclude that the lexical dilemma gives us little reason to prefer Archimedean views. Even if we give up on lexicality, (...) problems of the same kind remain. (shrink)

Arrhenius’s impossibility theorems purport to demonstrate that no population axiology can satisfy each of a small number of intuitively compelling adequacy conditions. However, it has recently been pointed out that each theorem depends on a dubious assumption: Finite Fine-Grainedness. This assumption states that there exists a finite sequence of slight welfare differences between any two welfare levels. Denying Finite Fine-Grainedness makes room for a lexical population axiology which satisfies all of the compelling adequacy conditions in each theorem. Therefore, Arrhenius’s theorems (...) fail to prove that there is no satisfactory population axiology. In this paper, I argue that Arrhenius’s theorems can be repurposed. Since all of our population-affecting actions have a non-zero probability of bringing about more than one distinct population, it is population prospect axiologies that are of practical relevance, and amended versions of Arrhenius’s theorems demonstrate that there is no satisfactory population prospect axiology. These impossibility theorems do not depend on Finite Fine-Grainedness, so lexical views do not escape them. (shrink)

I explain the shutdown problem: the problem of designing artificial agents that (1) shut down when a shutdown button is pressed, (2) don’t try to prevent or cause the pressing of the shutdown button, and (3) otherwise pursue goals competently. I prove three theorems that make the difficulty precise. These theorems show that agents satisfying some innocuous-seeming conditions will often try to prevent or cause the pressing of the shutdown button, even in cases where it’s costly to do so. And (...) patience trades off against shutdownability: the more patient an agent, the greater the costs that agent is willing to incur to manipulate the shutdown button. I end by noting that these theorems can guide our search for solutions. (shrink)

Lewis signalling games are often used to explain how it is possible for simple agents to develop systems of conventional semantic meaning. In these games, all players obtain identical payoffs in every outcome. This is an unrealistic payoff structure, but it is often employed because it is thought that semantic meaning will not emerge if interests conflict. Here it is shown that not only is conventional meaning possible when interests conflict, but it is the most likely outcome in a finite (...) population model of learning known as the Moran process. On the basis of this result it is suggested that evolutionary game theory’s standard models may yield results that are systematically distorted for a class of signalling games that have the abstract structure of social dilemmas. 1 Introduction2 The Seduction Game3 Imitation Dynamics with Small Mutations4 Dynamics with Unverifiable Message5 Analysis of a Related Three-Strategy Game6 Conclusion.

Critical-set views avoid the Repugnant Conclusion by subtracting some constant from the welfare score of each life in a population. These views are thus sensitive to facts about biographical identity: identity between lives. In this paper, I argue that questions of biographical identity give us reason to reject critical-set views and embrace the total view. I end with a practical implication. If we shift our credences towards the total view, we should also shift our efforts towards ensuring that humanity survives (...) for the long term. (shrink)

Scientific research that could cause grave harm, either through accident or intentional malevolence, is known as dual-use research. Recent high-profile cases of dual-use research in the life sciences have led to debate about the extent to which restrictions on the conduct and dissemination of such research may impede scientific progress. We adapt formal models of scientific networks to systematically explore the effects that different regulatory schemes may have on a community’s ability to learn about the world. Our results suggest that, (...) contrary to common wisdom, some restrictions on the conduct and dissemination of dual-use research do not inhibit scientific progress and may actually aid communities in learning.

I explain and motivate the shutdown problem: the problem of creating artificial agents that (1) shut down when a shutdown button is pressed, (2) don’t try to prevent or cause the pressing of the shutdown button, and (3) otherwise pursue goals competently. I then propose a solution: train agents to have incomplete preferences. Specifically, I propose that we train agents to lack a preference between every pair of different-length trajectories. I suggest a way to train such agents using reinforcement learning: (...) we give the agent lower reward for repeatedly choosing same-length trajectories. (shrink)

Person-affecting views in population ethics state that (in cases where all else is equal) we’re permitted but not required to create people who would enjoy good lives. In this paper, I present an argument against every possible variety of person-affecting view. The argument takes the form of a dilemma. Narrow person-affecting views must embrace at least one of three implausible verdicts in a case that I call ‘Expanded Non-Identity.’ Wide person-affecting views run into trouble in a case that I call (...) ‘Two-Shot Non-Identity.’ One plausible practical upshot of my argument is as follows: we individuals and our governments should be doing more to reduce the risk of human extinction this century.
