This paper gives an account of evolutionary explanations in biology. Briefly, the explanations I am primarily concerned with are explanations of adaptations. These explanations are contrasted with other nonteleological evolutionary explanations. The distinction is made by distinguishing the different kinds of questions these different explanations serve to answer. The sense in which explanations of adaptations are teleological is spelled out.

Population-level theories of evolution—the stock and trade of population genetics—are statistical theories par excellence. But what accounts for the statistical character of population-level phenomena? One view is that the population-level statistics are a product of, are generated by, probabilities that attach to the individuals in the population. On this conception, population-level phenomena are explained by individual-level probabilities and their population-level combinations. Another view, which arguably goes back to Fisher but has been defended recently, is that the population-level statistics are sui (...) generis, that they somehow emerge from the underlying deterministic behavior of the individuals composing the population. Walsh et al. label this the statistical interpretation. We are not willing to give them that term, since everyone will admit that the population-level theories of evolution are statistical, so we will call this the emergentist statistical interpretation. Our goals are to show that: This interpretation is based on gross factual errors concerning the practice of evolutionary biology, concerning both what is done and what can be done; its adoption would entail giving up on most of the explanatory and predictive projects of evolutionary biology; and finally a rival interpretation, which we will label the propensity statistical interpretation succeeds exactly where the emergentist interpretation fails.

In this paper the common association between ontological reductionism and a methodological position called 'Mechanism' is discussed. Three major points are argued for: (1) Mechanism is not to be identified with reductionism in any of its forms; in fact, mechanism leads to a non-reductionist ontology. (2) Biological methodology is thoroughly mechanistic. (3) Mechanism is compatible with at least one form of teleology. Along the way the nature and value of scientific explanations, some recent controversies in biology and why reductionism has (...) proven to be such an attractive position are discussed. (shrink)

Empirically successful scientific theories are intellectual hurricanes. They flood lowlands set aside for worries about definitions. They carry away philosophical reflections that are less dense than the accumulated scientific findings that give these storms their strength, and they fundamentally reshape the conceptual landscape. The history of scholarship reveals that once an empirically corroborated scientific theory explains and predicts phenomena in some domain noticeably better than the available alternatives (whether those alternatives are scientific theories or not), among experts at least, the (...) process of conceptualizing those phenomena, thereafter, mostly floats along on the surface of debates about the comparative scientific merits of that theory and its competitors. Earlier debates about definitions lose most of their interest until new theories arise that generate new, less easily managed empirical findings in the pertinent domains. Across the centuries, the fates of such concepts as ‘inertia’ and ‘planet’ are fitting illustrations of these patterns, as are, more recently, the fates of such concepts as ‘gene’ and ‘deciding’ (aka “decision making”).

Research suggests political identity has strong influence over individuals’ attitudes and beliefs, which in turn can affect their behavior. Likewise, firsthand experience with an issue can also affect attitudes and beliefs. A large survey of Americans was analyzed to investigate the effects of both political identity and personal impact on individuals’ reactions to the COVID-19 pandemic. Results show that political identity and personal impact influenced the American public’s attitudes about and response to COVID-19. Consistent with prior research, political identity exerted (...) a strong influence on self-reports of emotional distress, threat perception, discomfort with exposure, support for restrictions, and perception of under/overreaction by individuals and institutions. The difference between Democrats and Republican responses were consistent with their normative value differences and with the contemporary partisan messaging. Personal impact exerted a comparatively weaker influence on reported emotional distress and threat perception. Both factors had a weak influence on appraisal of individual and government responses. The dominating influence of political identity carried over into the bivariate relations among these self-reported attitudes and responses. In particular, the appraisal of government response divided along party lines, tied to opposing views of whether there has been over- or under-reaction to the pandemic. The dominance of political identity has important implications for crisis management and reflects the influence of normative value differences between the parties, partisan messaging on the pandemic, and polarization in American politics.

Aristotle's observation that all human beings by nature desire to know aptly captures the spirit of "intellectualist" research in psychology and anthropology. Intellectualists in these fields agree that humans' have fundamental explanatory interests (which reflect their rationality) and that the idioms in which their explanations are couched can differ considerably across places and times (both historical and developmental). Intellectualists in developmental psychology (e.g., Gopnik and Meltzoff, 1997) maintain that young children's conceptual structures, like those of scientists, are theories and that (...) their conceptual development--like the development of science--is a process of theory formation and change. They speculate that our explanatory preoccupations result, at least in part, from a natural drive to develop theories. Intellectualists in the anthropology of religion (e.g., Horton, 1970 and 1993) hold that, although it may do many other things as well, religion is primarily concerned with providing explanatory theories. They maintain that religion and science have the same explanatory goals; only the idioms of their explanations differ. The connections between the concern for explanation, the pursuit of science, the persistence of religion, and the cognitive processes underlying each clearly merit further examination. By considering both their cultural manifestations and their cognitive foundations, I hope to clarify not only how science and religion are related but some of the ways their explanatory projects differ. I shall argue that, despite their centuries' old antagonisms, no development in science will ever seriously threaten the persistence of religion or the forms of explanation religion employs or the emergence of new religions. (I strongly suspect that science will never seriously threaten the persistence of particular religions either, but I only aim to defend the weaker, collective claim here.) In this paper's fourth section I shall show that religion and its characteristic forms of explanation 1 are a natural outgrowth of the character and content of human association and cognition..

These days 'evolution' is usually defined as any change in the relative frequencies of genes in a population over time. This definition and some obvious alternatives are examined and rejected. The criticism of these definitions points out the need for a more holistic analysis of genotypes. I attempt such analysis by introducing measures of similarity of whole genotypes and then by grouping genotypes into similarity classes. Three sorts of measures of similarity are examined: a measure of structural similarity, a measure (...) of functional similarity and one of relational or historical similarity. The functional approach is shown to be superior and a definition of 'evolution' is suggested. (shrink)

Bringing Ritual to Mind explores the cognitive and psychological foundations of religious ritual systems. Participants must recall their rituals well enough to ensure a sense of continuity across performances, and those rituals must motivate them to transmit and re-perform them. Most religious rituals the world over exploit either high performance frequency or extraordinary emotional stimulation to enhance their recollection. But why do some rituals exploit the first of these variables while others exploit the second? McCauley and Lawson advance the ritual (...) form hypothesis, arguing that participants' cognitive representations of ritual form explain why. Reviewing evidence from cognitive, developmental and social psychology and from cultural anthropology and the history of religions, they utilize dynamical systems tools to explain the recurrent evolutionary trajectories religions exhibit.

In this paper we first briefly review Bell's (1964, 1966) Theorem to see how it invalidates any deterministic "hidden variable" account of the apparent indeterminacy of quantum mechanics (QM). Then we show that quantum uncertainty, at the level of DNA mutations, can "percolate" up to have major populational effects. Interesting as this point may be it does not show any autonomous indeterminism of the evolutionary process. In the next two sections we investigate drift and natural selection as the locus of (...) autonomous biological indeterminacy. Here we conclude that the population-level indeterminacy of natural selection and drift are ultimately based on the assumption of a fundamental indeterminacy at the level of the lives and deaths of individual organisms. The following section examines this assumption and defends it from the determinists' attack. Then we show that, even if one rejects the assumption, there is still an important reason why one might think evolutionary theory (ET) is autonomously indeterministic. In the concluding section we contrast the arguments we have mounted against a deterministic hidden variable account of ET with the proof of the impossibility of such an account of QM. (shrink)

Hearing Voices and Other Unusual Experiences examines the long-recognized and striking similarities between features of mental disorders and features of religions. Robert McCauley and George Graham emphasize underlying cognitive continuities between familiar features of religiosity, of mental disorders, and of everyday thinking and action. They contend that much religious thought and behavior can be explained in terms of the cultural activation of humans' natural cognitive systems, which address matters that are essential to human survival: hazard precautions, agency detection, language (...) processing, and theory of mind. Those systems produce responses to cultural stimuli that may mimic features of cognition and conduct associated with mental disorders, but are sometimes coded as "religious" depending on the context. Their approach promises to shed light on both mental abnormalities and religiosity. (shrink)

Abstract Like the logical empiricists many contemporary philosophers wish to bring the determinateness of scientific judgment to epistemology. Recent efforts to naturalise epistemology (such as those of the Churchlands) seem to jeopardise the position of epistemology as a normative discipline. Putnam argues that attempts to naturalise epistemology are self?refuting. My goal is not to defeat the project for the naturalisation of epistemology, but rather to help clarify what it does and does not amount to. I maintain that attempts to completely (...) eliminate the normative will be either forever incomplete or inimical to the progress of science. However, because it is the first horn of this dilemma which will prevail, these considerations do not undermine the importance of future epistemology carefully attending to the results of the relevant sciences.

This anthology collects some of the most important papers on what is believed to be the major force in evolution, natural selection. An issue of great consequence in the philosophy of biology concerns the levels at which, and the units upon which selection acts. In recent years, biologists and philosophers have published a large number of papers bearing on this subject. The papers selected for inclusion in this book are divided into three main sections covering the history of the subject, (...) explaining its conceptual foundations, and focusing on kin and group selection and higher levels of selection.One of the book's interesting features is that it draws together material from the biological and philosophical literatures. The philosophical literature, having thoroughly absorbed the biological material, now offers conceptual tools suitable for the reworking of the biological arguments. Although a full symbiosis has yet to develop, this anthology offers a unique resource for students in both biology and philosophy.Robert N.

The principle of natural selection is stated. It connects fitness values (actual reproductive success) with expected fitness values. The term 'adaptedness' is used for expected fitness values. The principle of natural selection explains differential fitness in terms of relative adaptedness. It is argued that this principle is absolutely central to Darwinian evolutionary theory. The empirical content of the principle of natural selection is examined. It is argued that the principle itself has no empirical biological content, but that the presuppositions of (...) its applicability are empirical. They form the empirical biological core of evolutionary theory. (shrink)

Recent theoretical work on the psychology of categorization emphasizes the role cognitive constructs play in perception and categorization. This approach supports Putnam's rejection of metaphysical realism. However, the experimental findings concerning basic level categories, in particular, suggest that robust stabilitites among our systems of empirical concepts persist in the face of considerable theoretical diversity and change. These stabilities undermine Putnam's strongest negative conclusions concerning the correspondence theory of truth (once it is uncoupled from metaphysical realism). The centrality of a correspondence (...) criterion of truth (in a larger theory of truth) is psychologically inescapable, rationally indispensable, and (therefore) epistemologically fundamental.

Drift is to evolution as inertia is to Newtonian mechanics. Both are the "natural" or default states of the systems to which they apply. Both are governed by zero-force laws. The zero-force law in biology is stated here for the first time.

Prudence, if not sheer logical necessity, dictates that when discussing something, it helps to have some idea of what you are talking about. This is why even the most experienced scholars periodically discuss their terms.

Richard Lewontin's (1970) early work on the units of selection initiated the conceptual and theoretical investigations that have led to the hierarchical perspective on selection that has reached near consensus status today. This paper explores other aspects of his work, work on what he termed continuity and quasi-independence, that connect to contemporary explorations of modularity in development and evolution. I characterize such modules and argue that they are the true units of selection in that they are what evolution by natural (...) selection individuates, selects among, and transforms. (shrink)

After distinguishing three kinds of pluralism, an individualist pluralism at one pole, a communalist pluralism at the other, and a third more complex concept ofpluralism, I address the meaning of commitment in America as iIIuminated by these distinctions. This continues a line opened up in Habits of the Heart. An earlierversion of this paper was presented at Marquette University in the Edward J. O’Donnell, S.J., Distinguished Lecture Series.

Unified, all-purpose, philosophical models of reduction in science lack resources for capturing varieties of cross-scientific relations that have proven critical to understanding some scientific achievements. Not only do those models obscure the distinction between successional and cross-scientific relations, their preoccupations with the structures of both theories and things provide no means for accommodating the contributions to various sciences of theories and research about long-term diachronic processes involving large-scale, distributed systems. Darwin's theory of evolution by natural selection is the parade case. (...) Explanatory pluralism accommodates a wider range of connections between theories and inquiries in science than all-purpose models of reduction do. Consequently, it provides analytical tools for understanding the roles of the theoretical proposals about the evolution of the human mind/brain that have proliferated over the last two decades. Those proposals have testable implications pertaining to both structure and processing in the modern human mind/brain. An example of such research illustrates how those proposals and investigative tools and experiments cut across both explanatory levels and modes of analysis within the cognitive sciences and how those studies can yield evidence that bears on the assessment of competing theories and models.

Kant held that “an incentive can determine the will [Willkür] to action only so far as the individual has incorporated it into his maxim”, a view dubbed the “Incorporation Thesis” by Henry Allison (hereafter, “IT”). Although many see IT as basic to Kant’s views on agency, it also seems irreconcilable with the possibility of a kind of weakness, the kind exhibited by a person who acts on incentives that run contrary to principles she holds dear. The problem is this: According (...) to IT, if an incentive determines the will of the weak person when she acts contrary to her principles, then it must be the case that she incorporated that incentive into her maxim. But that in turn means that she has made it her principle to act on the wayward incentive, and so is not, after all, exhibiting weakness in failing to follow her own principles, but at best simply dropping one principle in favor of another. So either the weak person does not incorporate the wayward incentive into her maxim and IT is false, or she does incorporate it and weakness is impossible. (shrink)

Cognitive approaches to religious phenomena have attracted considerable interdisciplinary attention since their emergence a couple of decades ago. Proponents offer explanatory accounts of the content and transmission of religious thought and behavior in terms of underlying cognition. A central claim is that the cross‐cultural recurrence and historical persistence of religion is attributable to the cognitive naturalness of religious ideas, i.e., attributable to the readiness, the ease, and the speed with which human minds acquire and process popular religious representations. In this (...) article, we primarily provide an introductory summary of foundational questions, assumptions, and hypotheses in this field, including some discussion of features distinguishing cognitive science approaches to religion from established psychological approaches. Relevant ethnographic and experimental evidence illustrate and substantiate core claims. Finally, we briefly consider the broader implications of these cognitive approaches for the appropriateness of ‘religion’ as an explanatorily useful category in the social sciences. (shrink)

The emergence of cognitive science over the past thirty years has stimulated new approaches to traditional problems and materials in well-established disciplines. Those approaches have generated new insights and reinvigorated aspirations for theories in the sciences of the socio-cultural (about the structures and uses of symbols and the cognitive processes underlying them) that are both more systematic and more accountable empirically than the recently available alternatives. Without rejecting interpretive proposals, projects in both the cognitive science of religion and in cognitive (...) archaeology seek to redress imbalances within those disciplines favoring the interpretive over the explanatory. (See Lawson and McCauley, 1990 and Renfrew, 1994a, respectively.) Both projects aim to reinvigorate scientific aspirations without reviving any sort of scientistic or explanatory exclusivism. Both have arisen, in part, in response to the science-bashing crusades that have enjoyed such prominence in both disciplines over the past twenty years. With the exception, perhaps, of linguistics, the influence of cognitive science has been as notable in archaeology and religious studies as it has been in any discipline in contemporary intellectual life. In both disciplines new sub-fields have begun to thrive, which take theoretical inspiration from cognitive science and, at least sometimes, deploy its findings and, in the case of the cognitive science of religion, even its methods in the course of testing their theories. This paper contains three sections. The first provides a framework for thinking about the constituents of culture as a means both for situating ritual and for considering its accessibility to cognitive and archaeological analysis. The second section outlines our theory of religious ritual competence and the ritual form hypothesis. The final section reviews the theory=s predictions about an assortment of properties of both individual religious rituals and religious ritual systems. It includes occasional speculations about some of the theory=s possible implications for some archaeological matters. A word of caution before we begin .. (shrink)
