Organisms' environments are thought to play a fundamental role in determining their fitness and hence in natural selection. Existing intuitive conceptions of environment are sufficient for biological practice. I argue, however, that attempts to produce a general characterization of fitness and natural selection are incomplete without the help of general conceptions of what conditions are included in the environment. Thus there is a "problem of the reference environment"—more particularly, problems of specifying principles which pick out those environmental conditions which determine (...) fitness. I distinguish various reference environment problems and propose solutions to some of them. While there has been a limited amount of work on problems concerning what I call "subenvironments", there appears to be no earlier work on problems of what I call the "whole environment". The first solution I propose for a whole environment problem specifies the overall environment for natural selection on a set of biological types present in a population over a specified period of time. The second specifies an environment relevant to extinction of types in a population; this kind of environment is especially relevant to certain kinds of long-term evolution. (shrink)

I describe a realist, ontologically objective interpretation of probability, "far-flung frequency (FFF) mechanistic probability". FFF mechanistic probability is defined in terms of facts about the causal structure of devices and certain sets of frequencies in the actual world. Though defined partly in terms of frequencies, FFF mechanistic probability avoids many drawbacks of well-known frequency theories and helps causally explain stable frequencies, which will usually be close to the values of mechanistic probabilities. I also argue that it's a virtue rather than (...) a failing of FFF mechanistic probability that it does not define single-case chances, and compare some aspects of my interpretation to a recent interpretation proposed by Strevens.

One controversy about the existence of so called evolutionary forces such as natural selection and random genetic drift concerns the sense in which such “forces” can be said to interact. In this paper I explain how natural selection and random drift can interact. In particular, I show how population-level probabilities can be derived from individual-level probabilities, and explain the sense in which natural selection and drift are embodied in these population-level probabilities. I argue that whatever causal character the individual-level probabilities (...) have is then shared by the population-level probabilities, and that natural selection and random drift then have that same causal character. Moreover, natural selection and drift can then be viewed as two aspects of probability distributions over frequencies in populations of organisms. My characterization of population-level probabilities is largely neutral about what interpretation of probability is required, allowing my approach to support various positions on biological probabilities, including those which give biological probabilities one or another sort of causal character. ‡This paper has benefited from feedback on and discussions of this and earlier work.

It has been argued that biological fitness cannot be defined as expected number of offspring in all contexts. Some authors argue that fitness therefore merely satisfies a common schema or that no unified mathematical characterization of fitness is possible. I argue that comparative fitness must be relativized to an evolutionary effect; thus relativized, fitness can be given a unitary mathematical characterization in terms of probabilities of producing offspring and other effects. Such fitnesses will sometimes be defined in terms of probabilities (...) of effects occurring over the long term, but these probabilities nevertheless concern effects occurring over the short term. †To contact the author, please write to: Department of Philosophy, University of Alabama at Birmingham, HB 414A, 900 13th Street South, Birmingham, AL 35294‐1260; e‐mail: [email protected].

This chapter explores a philosophical hypothesis about the nature of (some) probabilities encountered in social sciences. It should be of interest to those with philosophical concerns about the foundations of probability, and to social scientists and philosophers of science who are somewhat puzzled by the nature of probability in social domains. As will become clear below, the chapter is not intended as a contribution to an empirical methodology such as a particular way of applying statistics.

Recent debate on the nature of probabilities in evolutionary biology has focused largely on the propensity interpretation of fitness (PIF), which defines fitness in terms of a conception of probability known as “propensity”. However, proponents of this conception of fitness have misconceived the role of probability in the constitution of fitness. First, discussions of probability and fitness have almost always focused on organism effect probability, the probability that an organism and its environment cause effects. I argue that much of the (...) probability relevant to fitness must be organism circumstance probability, the probability that an organism encounters particular, detailed circumstances within an environment, circumstances which are not the organism’s effects. Second, I argue in favor of the view that organism effect propensities either don’t exist or are not part of the basis of fitness, because they usually have values close to 0 or 1. More generally, I try to show that it is possible to develop a clearer conception of the role of probability in biological processes than earlier discussions have allowed. (shrink)

It’s recently been argued that biological fitness can’t change over the course of an organism’s life as a result of organisms’ behaviors. However, some characterizations of biological function and biological altruism tacitly or explicitly assume that an effect of a trait can change an organism’s fitness. In the first part of the paper, I explain that the core idea of changing fitness can be understood in terms of conditional probabilities defined over sequences of events in an organism’s life. The result (...) is a notion of “conditional fitness” which is static but which captures intuitions about apparent behavioral effects on fitness. The second part of the paper investigates the possibility of providing a systematic foundation for conditional fitness in terms of spaces of sequences of states of an organism and its environment. I argue that the resulting “organism–environment history conception” helps unify diverse biological perspectives, and may provide part of a metaphysics of natural selection. (shrink)

and was correct to conclude that the way a biological population is described should affect conclusions about whether natural selection occurs, but wrong to conclude that natural selection is therefore not a cause. After providing a new argument that ignored crucial biological details, I give a biological illustration that motivates a fairly extreme dependence on description. I argue that contrary to an implication of , biologists allow much flexibility in describing populations, as contemporary research on recent human evolution shows. Properly (...) understood, such description-dependence is consistent with descriptions capturing different causal relations involving the same population. I thus show that Walsh’s arguments fail for reasons that have not previously been understood; I argue that Walsh’s more recent “Sure Thing” argument fails for similar reasons. The resulting view provides a new perspective on causation in evolutionary processes. (shrink)

One finds intertwined with ideas at the core of evolutionary theory claims about frequencies in counterfactual and infinitely large populations of organisms, as well as in sets of populations of organisms. One also finds claims about frequencies in counterfactual and infinitely large populations—of events—at the core of an answer to a question concerning the foundations of evolutionary theory. The question is this: To what do the numerical probabilities found throughout evolutionary theory correspond? The answer in question says that evolutionary probabilities (...) are “hypothetical frequencies” (including what are sometimes called “long-run frequencies” and “long-run propensities”). In this paper, I review two arguments against hypothetical frequencies. The arguments have implications for the interpretation of evolutionary probabilities, but more importantly, they seem to raise problems for biologists’ claims about frequencies in counterfactual or infinite populations of organisms and sets of populations of organisms. I argue that when properly understood, claims about frequencies in large and infinite populations of organisms and sets of populations are not threatened by the arguments. Seeing why gives us a clearer understanding of the nature of counterfactual and infinite population claims and probability in evolutionary theory. (shrink)

I define a concept of causal probability and apply it to questions about the role of probability in evolutionary processes. Causal probability is defined in terms of manipulation of patterns in empirical outcomes by manipulating properties that realize objective probabilities. The concept of causal probability allows us see how probabilities characterized by different interpretations of probability can share a similar causal character, and does so in such way as to allow new inferences about relationships between probabilities realized in different chance (...) setups. I clarify relations between probabilities and properties defined in terms of them, and argue that certain widespread uses of computer simulations in evolutionary biology show that many probabilities relevant to evolutionary outcomes are causal probabilities. This supports the claim that higher-level properties such as biological fitness and processes such as natural selection are causal properties and processes, contrary to what some authors have argued.

Sewall Wright ’s FST is a mathematical test widely used in empirical applications to characterize genetic and other differences between subpopulations, and to identify causes of those differences. Cockerham and Weir’s popular approach to statistical estimation of FST is based on an assumption sometimes formulated as a claim that actual populations tested are sampled from.

Pseudorandom number generating algorithms play crucial roles in computer modeling and statistical modeling, but they have received little attention from philosophers of science. I revisit an argument that the success of practices in evolutionary biology using such algorithms in computer simulations provides evidence that evolutionary processes incorporate objective probabilities. I discuss the kind of stochasticity that pseudorandom number generators provide--what I call "pseudochance"--and argue that the argument from simulation practice, as well as other arguments, supports the view that evolutionary processes (...) incorporate pseudochance. I suggest that similar arguments might be given in other domains of science. (shrink)

I investigate the structure of an argument that culture cannot be maintained in a population if each individual learns only from a single person. This appears to conflict with many models of cultural transmission and real-world cases. I resolve the first problem by showing that one of the models central to the argument is conceptually analogous and mathematically equivalent to one used to investigate the evolution of sexual reproduction. I resolve the second by arguing that probabilistic models of epistemological coherence (...) can be reinterpreted as models of support between cultural variants—illustrating the idea with a new model. (shrink)

Focus on the way in which cultural variants affect other variants' probabilities of transmission in modeling and empirical work can enrich Kline's conceptualization of teaching. For example, the problem of communicating complex cumulative culture is an adaptive problem; teaching methods that manage transmission so that acquisition of some cultural variants increases the probability of acquiring others, provide a partial solution.

Smaldino suggests that patterns that give rise to group-level cultural traits can also increase individual-level cultural diversity. I distinguish social roles and related social network structures and discuss ways in which each might maintain diversity. I suggest that cognitive analogs of “cohesion,” a property of networks that helps maintenance of diversity, might mediate the effects of social roles on diversity.

Research in evolutionary ecology on random foraging seems to ignore the possibility that some random foraging is an adaptation not to environmental randomness, but to what Wimsatt called “perceived randomness”. This occurs when environmental features are unpredictable, whether physically random or not. Mere perceived randomness may occur, for example, due to effects of climate change or certain kinds of static landscape variation. I argue that an important mathematical model concerning random foraging doesn’t depend on environmental randomness, despite contrary remarks by (...) researchers. I use computer simulations to illustrate the idea that random foraging is an adaptation to mere perceived randomness. (shrink)

In a recent paper in Psychological Science, Kouider and Dupoux reported obtaining unconscious Stroop priming only when subjects had partial awareness of the masked distractor words . Kouider and Dupoux conjectured that semantic priming occurs only when such partial awareness is present. The present experiments tested this conjecture in an affective categorization priming task that differed from Kouider and Dupoux’s in using masked distractors that subjects had practiced earlier as visible words. Experiment 1 showed priming from practiced words when subjects (...) had no partial awareness of those words. Experiment 2 showed that, in the absence of partial awareness, practiced words yielded priming but not-practiced words did not. Experiment 3 corroborated Experiment 1 and 2s results using a different test of partial awareness. These results suggest that unconscious processing of subword elements drives masked semantic priming by practiced words. (shrink)

In the debate over clinicians’ conscience, there is a greater ethical, legal, and scholarly focus on negative, rather than positive, claims of conscience. This asymmetry produces a seemingly unjustified double standard with respect to clinicians’ conscience under the law. For example, a Roman Catholic physician working at a secular institution may refuse to provide physician-aid-in-dying on the basis of conscience, but a secular physician working at a Roman Catholic institution may not insist on providing physician-aid-in-dying on the basis of conscience. (...) This article outlines arguments against this asymmetry and critiques them for failing to distinguish between positive claims of conscience as positive or negative rights. I suggest the asymmetry debate should be focused on whether positive claims of conscience as positive rights ought to enjoy the same protections as negative claims of conscience. Clarifying the debate in this way helps elucidate some of the best reasons for the asymmetry, which these arguments have not addressed. This article does not take a definitive position on whether the asymmetry is justified, but attempts to bring some focus to the debate by directing arguments against the asymmetry to address the significant differences between positive claims of conscience as positive rights and negative claims of conscience.

Physicians generally recommend that patients resuscitated with naloxone after opioid overdose stay in the emergency department for a period of observation in order to prevent harm from delayed sequelae of opioid toxicity. Patients frequently refuse this period of observation despiteenefit to risk. Healthcare providers are thus confronted with the challenge of how best to protect the patient’s interests while also respecting autonomy, including assessing whether the patient is making an autonomous choice to refuse care. Previous studies have shown that physicians (...) have widely divergent approaches to navigating these conflicts. This paper reviews what is known about the effects of opioid use disorder on decision-making, and argues that some subset of these refusals are non-autonomous choices, even when patients appear to have decision making capacity. This conclusion has several implications for how physicians assess and respond to patients refusing medical recommendations after naloxone resuscitation. (shrink)

What is the proper role of a clinical ethics consultant’s religious beliefs in forming recommendations for clinical ethics consultation? Where Janet Malek has argued that religious belief should have no influence on the formation of a CEC’s recommendations, Clint Parker has argued a CEC should freely appeal to all their background beliefs, including religious beliefs, in formulating their recommendations. In this paper, I critique both their views by arguing the position envisioned by Malek puts the CEC too far from religion (...) and the position envisioned by Parker puts the CEC too close. For a CEC to give recommendations about what is morally prohibited, permissible, or obligatory in the clinic, I propose a view of the CEC that is neither religious nor non-religious but quasi-religious. I argue that a quasi-religious approach avoids the problems of both religious and non-religious views while preserving their benefits. Additionally, a quasi-religious view resists the marginalization of “religious” traditions that occurs when secular ethicists come to think of their approach as somehow distinctly non-religious.

This paper provides a close reading of Erwin Straus’ “The Upright Posture” from a disability studies perspective. Straus argues that the upright posture dominates the human world. But he excludes those who dwell in it otherwise. By reviewing phenomenological disability literature, this paper asks what a disabled phenomenology would look like, one rooted in the problem of inclusion from the outset. Disabled phenomenology addresses ‘subjectivity’ critically, asking: what socio-material arrangements make subjectivity possible in the first place? This project is, I (...) argue, equal parts political economy and existential phenomenology. I conclude with some suggestions for future research. (shrink)

Legal precedent, professional‐society statements, and even many medical ethicists agree that some situations may call for a clinician to engage in an act of lying or nonlying deception of a patient or patient's family member. Still, the moral terrain of clinical deception is largely uncharted, and when it comes to practical guidance for clinicians, many might think that ethicists offer nothing more than the rule never to deceive. This guidance is insufficient to meet the real‐world demands of clinical practice, and (...) this article endeavors to articulate a framework to help clinicians better navigate the ethics of clinical deceit. The framework articulates four morally relevant dimensions of a potential deceptive act that should be examined to better determine the moral justification that might be required: the target of the act, the nature of the information, the nature of the act, and the context of the act.

In this acclaimed exploration of the search for "authentic" individual identity, Marshall Berman explores the historical experiences and needs out of which this new radicalism arose. Focussing on eighteenth-century Paris, a time and place in which a distinctively modern form of society was just coming into its own, Berman shows how the ideal of authenticity—of a self that could organize the individual's energy and direct it toward his own happiness—articulated eighteenth-century man's deepest responses to this brave new world, and (...) his most ardent hope for a new life in it. Exploring in particular the ideas of Montesquieu and Rousseau, Berman shows how the ideal of authenticity was radically opposed to the bourgeois, capitalistic idea of "self-interest.". (shrink)

In a recent issue of the Journal of Medicine and Philosophy, several scholars wrote on the topic of ethics expertise in clinical ethics consultation. The articles in this issue exemplified what we consider to be two troubling trends in the quest to articulate a unique expertise for clinical ethicists. The first trend, exemplified in the work of Lisa Rasmussen, is an attempt to define a role for clinical ethicists that denies they have ethics expertise. Rasmussen cites the dependence of ethical (...) expertise on irresolvable meta-ethical debates as the reason for this move. We argue against this deflationary strategy because it ends up smuggling in meta-ethical assumptions it claims to avoid. Specifically, we critique Rasmussen’s distinction between the ethical and normative features of clinical ethics cases. The second trend, exemplified in the work of Dien Ho, also attempts to avoid meta-ethics. However, unlike Rasmussen, Ho tries to articulate a notion of ethics expertise that does not rely upon meta-ethics. Specifically, we critique Ho’s attempts to explain how clinical ethicists can resolve moral disputes using what he calls the “Default Principle” and “arguments by parity.” We show that these strategies do not work unless those with the moral disagreement already share certain meta-ethical assumptions. Ultimately, we argue that the two trends of attempting to avoid meta-ethics by denying that clinical ethicists have ethics expertise, and attempting to articulate how ethics expertise can be used to resolve disputes without meta-ethics both fail because they do not, in fact, avoid doing meta-ethics. We conclude that these trends detract from what clinical ethics consultation was founded to do and ought to still be doing—provide moral guidance, which requires ethics expertise, and engagement with meta-ethics. To speak of ethicists without ethics expertise leaves their role in the clinic dangerously unclear and unjustified. (shrink)

The national standards for clinical ethics consultation set forth by the American Society for Bioethics and Humanities endorse an “ethics facilitation” approach, which characterizes the role of the ethicist as one skilled at facilitating consensus within the range of ethically acceptable options. To determine the range of ethically acceptable options, ASBH recommends the standard model of decision-making, which is grounded in the values of autonomy, beneficence, nonmaleficence, and justice. H. Tristram Engelhardt Jr. has sharply criticized the standard model for presuming (...) contentful moral claims in circumscribing the range of ethically acceptable options, which, he argues, cannot be rationally justified in a pluralistic context. Engelhardt’s solution is a secular clinical ethics based on a contentless principle of permission. The first part of this article lays out Engelhardt’s negative claim, that reason cannot establish contentful moral claims, and his positive claim, that secular clinical ethics ought to be based on a contentless principle of permission. The second part critiques these negative and positive claims. The purpose of this paper is to defend secular clinical ethics expertise—defined as the ability of ethicists to offer justified moral recommendations grounded in consensus positions endorsed by the American Society for Bioethics and Humanities—from the radical critiques of Engelhardt, who argues that no moral or metaphysical claims, and hence no bioethical consensus, can be rationally justified. Engelhardt’s critiques have caused some to worry that secular clinical ethics is in a state of theoretical crisis; this article concludes that Engelhardt’s view is an unstable basis for that worry.

Considered the most original thinker in the Italian philosophical tradition, Giambattista Vico has been the object of much scholarly attention but little consensus. In this new interpretation, David L. Marshall examines the entirety of Vico's oeuvre and situates him in the political context of early modern Naples. He demonstrates Vico's significance as a theorist who adapted the discipline of rhetoric to modern conditions. Marshall presents Vico's work as an effort to resolve a contradiction. As a professor of rhetoric (...) at the University of Naples, Vico had a deep investment in the explanatory power of classical rhetorical thought, especially that of Aristotle, Cicero, and Quintilian. Yet as a historian of the failure of Naples as a self-determining political community, he had no illusions about the possibility or worth of democratic and republican systems of government in the post-classical world. As Marshall demonstrates, by jettisoning the assumption that rhetoric only illuminates direct, face-to-face interactions between orator and auditor, Vico reinvented rhetoric for a modern world in which the Greek polis and the Roman res publica are no longer paradigmatic for political thought.

While many Catholic hospitals permit the prescription of the emergency contraception drug levonorgestrel for rape victims, some continue to prohibit this practice as a matter of institutional conscience. While the standard approach to this issue has been to offer an argument that levonorgestrel either is or is not morally permissible, we have taken a different tack. We begin by briefly describing and acknowledging that reasonable disagreement exists on this question (part one), and then arguing that the reasonable disagreement itself can (...) serve as a compelling basis for Catholic leadership at hospitals that prohibit emergency contraception for rape victims to accommodate physicians who wish to provide levonorgestrel as a matter of conscience (part two).

Given recent legal developments in the United States, now is a critical time to draw attention to how ‘conscientious objection’ is sometimes used by health care providers to discriminate against the LGBTQ community. We review legal developments from 2019 and present several cases where health care providers used conscientious objection in ways that discriminate against the LGBTQ community, resulting in damaged trust by this underserved population. We then discuss two important conceptual points in this debate. The first involves the interpretation (...) of discrimination (provider versus patient-centered views), and we argue for a patient-centered view; the second involves the use of the people versus procedure distinction to reach a compromise between LGBTQ individuals and the clinicians who do not want to treat them. We argue the distinction is problematic when applied to treatment of the LGBTQ population. (shrink)

The legal and ethical asymmetry between honoring positive claims of conscience versus negative claims of conscience was recently analyzed by several articles in this journal. The first author of this article (ALB) identified unique but defeasible reasons against honoring positive claims of conscience, such as the greater threat they post to institutional values and institutional resources than negative claims of conscience. However, ALB wrote, when these reasons can be overcome, positive claims of conscience should enjoy the same ethical and legal (...) respect as negative claims of conscience. This article argues that the prescription of birth control by non-Roman Catholic physicians in Roman Catholic institutions is an example of a positive claim of conscience that can overcome concerns of institutional values and resources, and therefore ought to receive the same ethical respect and legal protection as negative claims of conscience. In making this argument, this article also responds to several of the thoughtful comments raised by Alberto Giubilini and Dominic Wilkinson. (shrink)

Our aim in this article is to bring some clarity to the clinical ethics expertise debate by critiquing and replacing the taxonomy offered by the Core Competencies report. The orienting question for our taxonomy is: Can clinical ethicists offer justified, normative recommendations for active patient cases? Views that answer “no” are characterized as a “negative” view of clinical ethics expertise and are further differentiated based on (a) why they think ethicists cannot give justified normative recommendations and (b) what they think (...) ethicists can offer, if they cannot offer recommendations. Views that answer “yes” to the orienting question are characterized as a “positive” view of clinical ethics expertise. Positive views are distinguished according to four additional questions. First (P1), how are those recommendations generated? Second (P2), what is the nature of the recommendations? Third (P3), we ask, how are the recommendations justified? And finally (P4), how are the recommendations communicated? (shrink)

This article describes and rejects three standard views of reason in secular clinical ethics. The first, instrumental reason view, affirms that reason may be used to draw conceptual distinctions, map moral geography, and identify invalid forms of argumentation, but prohibits recommendations because reason cannot justify any content-full moral or metaphysical commitments. The second, public reason view, affirms instrumental reason, and claims ethicists may make recommendations grounded in the moral and metaphysical commitments of bioethical consensus. The third, comprehensive reason view, also (...) affirms instrumental reason, but encourages ethicists to make recommendations grounded in the moral and metaphysical commitments of their private worldviews. A compatibilist view of public reason is then defended, which holds that each standard view captures an important role for reason in different aspects of secular clinical ethics. The article ends by identifying three implications for enduring theoretical debates in clinical ethics. (shrink)
