In 2017 we published a paper in this journal proposing a philosophical framework for recognizing ecological communities as natural entities, the Evolutionary Community Concept. That paper attracted a lengthy reply; herein we take the opportunity to clarify critical aspects of the ECC and use a case study to demonstrate how the ECC can be made operational. We maintain the ECC provides a framework useful for establishing objectives associated with ongoing and proposed restoration and conservation efforts.

Recent work has suggested that conservation efforts such as restoration ecology and invasive species eradication are largely value-driven pursuits. Concurrently, changes to global climate are forcing ecologists to consider if and how collections of species will migrate, and whether or not we should be assisting such movements. Herein, we propose a philosophical framework which addresses these issues by utilizing ecological and evolutionary interrelationships to delineate individual ecological communities. Specifically, our Evolutionary Community Concept recognizes unique collections of species that interact and (...) have co-evolved in a given geographic area. We argue this concept has implications for a number of contemporary global conservation issues. Specifically, our framework allows us to establish a biological and science-driven context for making decisions regarding the restoration of systems and the removal of exotic species. The ECC also has implications for how we view shifts in species assemblages due to climate change and it advances our understanding of various ecological concepts, such as resilience. (shrink)

Increasingly, epistemologists are becoming interested in social structures and their effect on epistemic enterprises, but little attention has been paid to the proper distribution of experimental results among scientists. This paper will analyze a model first suggested by two economists, which nicely captures one type of learning situation faced by scientists. The results of a computer simulation study of this model provide two interesting conclusions. First, in some contexts, a community of scientists is, as a whole, more reliable when its (...) members are less aware of their colleagues' experimental results. Second, there is a robust tradeoff between the reliability of a community and the speed with which it reaches a correct conclusion. ‡The author would like to thank Brian Skyrms, Kyle Stanford, Jeffrey Barrett, Bruce Glymour, and the participants in the Social Dynamics Seminar at University of California–Irvine for their helpful comments.

Theories of emotion have often maintained artificial boundaries: for instance, that cognition and emotion are separable, and that an emotion concept is separable from the emotional events that comprise its category (e.g. “fear” is distinct from instances of fear). Over the past several years, research has dissolved these artificial boundaries, suggesting instead that conceptual construction is a domain-general process—a process by which the brain makes meaning of the world. The brain constructs emotion concepts, but also cognitions and perceptions, all in (...) the service of guiding action. In this view, concepts are multimodal constructions, dynamically prepared from a set of highly variable instances. This approach obviates old questions (e.g. how does cognition regulate emotion?) but generates new ones (e.g. how does a brain learn emotion concepts?). In this paper, we review this constructionist, predictive coding account of emotion, considering its implications for health and well-being, culture and development. (shrink)

There is significant interest in type-free systems that allow flexible self-application. Such systems are of interest in property theory, natural language semantics, the theory of truth, theoretical computer science, the theory of classes, and category theory. While there are a variety of proposed type-free systems, there is a particularly natural type-free system that we believe is prototypical: the logic of recursive algorithms. Algorithmic logic is the study of basic statements concerning algorithms and the algorithmic rules of inference between such statements. (...) As shown in [1], the threat of paradoxes, such as the Curry paradox, requires care in implementing rules of inference in this context. As in any type-free logic, some traditional rules will fail. The first part of the paper develops a rich collection of inference rules that do not lead to paradox. The second part identifies traditional rules of logic that are paradoxical in algorithmic logic, and so should be viewed with suspicion in type-free logic generally. (shrink)

Context: There is a growing recognition in consciousness science of the need for rigorous methods for obtaining accurate and detailed phenomenological reports of lived experience, i.e., descriptions of experience provided by the subject living them in the “first-person.” Problem: At the moment although introspection and debriefing interviews are sometimes used to guide the design of scientific studies of the mind, explicit description and evaluation of these methods and their results rarely appear in formal scientific discourse. Method: The recent publication of (...) an edited book of papers dedicated to the exploration of first-and second-person methods, Ten Years of Viewing from Within: The Legacy of Francisco Varela, serves as a starting point for a discussion of how these methods could be integrated into the growing discipline of consciousness science. We complement a brief review of the book with a critical analysis of the major pilot studies in Varela’s neurophenomenology, a research program that was explicitly devised to integrate disciplined experiential methods with the latest advances in neuroscience. Results: The book is a valuable resource for those who are interested in impressive recent advances in first- and second-person methods, as applied to the phenomenology of lived experience. However, our review of the neurophenomenology literature concludes that there is as yet no convincing example of these specialized techniques being used in combination with standard behavioral and neuroscientific approaches in consciousness science to produce results that could not have also been achieved by simpler methods of introspective reporting. Implications: The end of behaviorism and the acceptance of verbal reports of conscious experience have already enabled the beginning of a science of consciousness. It can only be of benefit if new first- and second-person methods become well-known across disciplines. Constructivist content: Constructivism has long been interested in the role of the observer in the constitution of our sense of reality, so these developments in the science of consciousness may open new avenues of constructivist research. More specifically, one of the ways in which the insights from first- and second-person methods are being validated is by recursively applying the methods to themselves; a practical application of an epistemological move that will be familiar to constructivists from the second-order cybernetics tradition.

Wittgenstein used the notion of a language game to illustrate how language is interwoven with action. Here we consider how successful linguistic discourse of the sort he described might emerge in the context of a self-assembling evolutionary game. More specifically, we consider how discourse and coordinated action might self-assemble in the context of two generalized signaling games. The first game shows how prospective language users might learn to initiate meaningful discourse. The second shows how more subtle varieties of discourse might (...) co-emerge with a meaningful language. (shrink)

Is fertility relevant to evolutionary analyses conducted in modern industrial societies? This question has been the subject of a highly contentious debate, beginning in the late 1980s and continuing to this day. Researchers in both evolutionary and social sciences have argued that the measurement of fitness-related traits (e.g., fertility) offers little insight into evolutionary processes, on the grounds that modern industrial environments differ so greatly from those of our ancestral past that our behavior can no longer be expected to be (...) adaptive. In contrast, we argue that fertility measurements in industrial society are essential for a complete evolutionary analysis: in particular, such data can provide evidence for any putative adaptive mismatch between ancestral environments and those of the present day, and they can provide insight into the selection pressures currently operating on contemporary populations. Having made this positive case, we then go on to discuss some challenges of fertility-related analyses among industrialized populations, particularly those that involve large-scale databases. These include “researcher degrees of freedom” (i.e., the choices made about which variables to analyze and how) and the different biases that may exist in such data. Despite these concerns, large datasets from multiple populations represent an excellent opportunity to test evolutionary hypotheses in great detail, enriching the evolutionary understanding of human behavior.

There exists substantial cultural variation in how emotions are expressed, but there is also considerable evidence for universal properties in facial and vocal affective expressions. This is the first empirical effort examining the perception of vocal emotional expressions across cultures with little common exposure to sources of emotion stimuli, such as mass media. Shuar hunter-horticulturalists from Amazonian Ecuador were able to reliably identify happy, angry, fearful and sad vocalizations produced by American native English speakers by matching emotional spoken utterances to (...) emotional expressions portrayed in pictured faces. The Shuar performed similarly to English speakers who heard the same utterances in a content-filtered condition. These data support the hypothesis that vocal emotional expressions of basic affective categories manifest themselves in similar ways across quite disparate cultures. (shrink)

We examine an argument for the non-context-freeness of English that has received virtually no discussion in the literature. It is based on adjuncts of the form 'X or no X', where X is a nominal. The construction has been held to exemplify unbounded syntactic reduplication. We argue that although the argument can be made in a mathematically valid form, its empirical basis is not secure. First, the claimed unbounded syntactic identity between nominals does not always hold in attested cases, and (...) second, an understanding of the semantics of the construction removes the necessity of making reference to any syntactic reduplication.

The significance of informed consent in research involving humans has been a topic of active debate in the last decade. Much of this debate, we submit, is predicated on an ideology of individualism. We draw on our experiences as anthropologists working in Western and non Western (Iban) health care settings to present ethnographic data derived from diverse scenes in which consent is gained. Employing classical anthropological ritual theory, we subject these observational data to comparative analysis. Our article argues that the (...) individualist assumptions underlying current bioethics guidelines do not have universal applicability, even in Western research settings. This is based on the recognition that the social world is constitutive of personhood in diverse forms, just one of which is individualistic. We submit that greater attention must be paid to the social relations the researcher inevitably engages in when conducting research involving other people, be this in the context of conventional medical research or anthropological field work. We propose, firstly, that the consenting process continues throughout the life of any research project, long after the signature has been secured, and secondly, that both group and individual dimensions of consent, and the sequence in which these dimensions are addressed, should be carefully considered in all cases where consent is sought.

Recently the intramural debate among Christians over the correct interpretation of Genesis 1 and the age of the earth has become heated between leaders of certain science-based ministries. A major point of contention revolves around the question of whether there was animal death before Adam and Eve’s first sin. Many young-earth proponents charge that if God allowed death before Adam and Eve sinned, then God would not be morally perfect. In this paper I propose and critique a logical argument from (...) these charges. First, I formulate a logical problem based on the claims of young-earth proponents. Next, I discuss several theistic interpretations of God’s moral perfection and explain how deontological and consequentialist interpretations are problematic. After this I discuss Aquinas’ interpretation of God’s moral perfection. Finally, I provide a solution to the problem of death before the fall using Aquinas’ interpretation. I conclude that it is not logically contradictory to believe that God is all-knowing, all-powerful, and all-good and that He created a world that initially contained animal death. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called 'subjective validation'. An objective validation of a statement can be accomplished by showing that the statement actually matches up to the way the world is; this can be done by comparing the statement to the world itself. Combined with other mistakes, like confirmation bias and availability error, subjective validation can fool people into thinking that psychics can read their minds, predict the future, or even communicate with the (...) dead. Although the subjective validation of Nostradamus's “predictions” doesn't fuel much else besides silly beliefs in the paranormal, falling prey to subjective validation can be much more costly. The same subjective validation “retrodiction” techniques are also used to interpret the prophecies of the Bible, like those that are supposedly in the Book of Revelation. (shrink)

FROST (copy 2): From the John Holmes Library collection.

Originally published in 1940, this book contains a succinct introduction to Boethius, the influential medieval philosopher who was writing during the final days of the Western Roman Empire. Barrett keeps the general reader in mind as she explains Boethius' philosophy and his role in keeping Greek thinking available to his fellow Romans even as they were being conquered by the Ostrogoths. This book will be of value to anyone with an interest in ancient thought and in Late Antique philosophy.

Neural language models (NLMs) are susceptible to producing inconsistent output. This paper proposes a new diagnosis as well as a novel remedy for NLMs' incoherence. We train NLMs on synthetic text corpora that are created by simulating text production in a society. For diagnostic purposes, we explicitly model the individual belief systems of artificial agents (authors) who produce corpus texts. NLMs, trained on those texts, can be shown to aggregate the judgments of individual authors during pre-training according to sentence-wise vote (...) ratios (roughly, reporting frequencies), which inevitably leads to so-called discursive dilemmas: aggregate judgments are inconsistent even though all individual belief states are consistent. As a remedy for such inconsistencies, we develop a self-training procedure—inspired by the concept of reflective equilibrium—that effectively reduces the extent of logical incoherence in a model's belief system, corrects global mis-confidence, and eventually allows the model to settle on a new, epistemically superior belief state. Thus, social choice theory helps to understand why NLMs are prone to produce inconsistencies; epistemology suggests how to get rid of them. (shrink)

Humans and many animals are capable of learning and learning how to learn better. We are concerned here with one way that reinforcement learners might learn how to learn better. In an experiment described by Harlow in (Psychol Rev 56:51–65, 1949) a group of rhesus monkeys learn a new way of learning in the context of a specific type of problem. We will consider how such agents might coevolve a new learning dynamics and new attendant saliences. To this end, we (...) propose a self-tuning dynamics that illustrates one way that a reinforcement learner might acquire forms of learning that are well-suited to context-specific problems. (shrink)

For many decades, researchers have explored the true potential of human achievement. The expertise field has come a long way since the early works of de Groot (1965) and Chase and Simon (1973). Since then, this inquiry has expanded into the areas of music, science, technology, sport, academia and art. Despite the vast amount of research to date, the capability of study methodologies to truly capture the nature of expertise remains questionable. Some considerations include (i) the individual bias in the (...) retrospective recall of developmental activities, (ii) the ability to develop ecologically valid tasks, and (iii) difficulties capturing the influence of confounding factors on expertise. This article proposes that expertise research in electronic sports (esports) presents an opportunity to overcome some of these considerations. Esports involves individuals or teams of players that compete in video game competitions via human-computer interaction. Advantages of applying the expert performance approach in esports include (i) developmental activities are objectively tracked and automatically logged online, (ii) the constraints of representative tasks correspond with the real-world environment of esports performance, and (iii) expertise has emerged without the influence of guided systematic training environments. Therefore, this article argues that esports research provides an ideal opportunity to further advance research on the development and assessment of human expertise. (shrink)

In addition to ensuring that appropriate standards of evidence are employed when attempting to identify adaptations, researchers should investigate all nonevolutionary factors that could potentially explain their results. Evolutionary analyses may be undermined by alternative, non-evolutionary explanations either because not all relevant information is included in an evolutionary analysis, or because inappropriate methods incapable of detecting an adaptation are employed.
