What sort of epistemic positions are compatible with inquiries driven by interrogative attitudes like wonder and puzzlement? The ignorance norm provides a partial answer: interrogative attitudes directed at a particular question are never compatible with knowledge of the question’s answer. But some are tempted to think that interrogative attitudes are incompatible with weaker positions like belief as well. This paper defends that the ignorance norm is exhaustive. All epistemic positions weaker than knowledge directed at the answer to a question are (...) compatible with having an interrogative attitude towards that question. We offer two arguments for this conclusion. The first is based on considerations about the role of hedging in inquiry. The second is conditional on considerations related to the aim of inquiry as a goal-directed activity. (shrink)

Highly idealized models, such as the Hawk-Dove game, are pervasive in biological theorizing. We argue that the process and motivation that leads to the introduction of various idealizations into these models is not adequately captured by Michael Weisberg’s taxonomy of three kinds of idealization. Consequently, a fourth kind of idealization is required, which we call hypothetical pattern idealization. This kind of idealization is used to construct models that aim to be explanatory but do not aim to be explanations.

Within the modeling literature, there is often an implicit assumption about the relationship between a given model and a scientific explanation. The goal of this article is to provide a unified framework with which to analyze the myriad relationships between a model and an explanation. Our framework distinguishes two fundamental kinds of relationships. The first is metaphysical, where the model is identified as an explanation or as a partial explanation. The second is epistemological, where the model produces understanding that is (...) related to the explanation of interest. Our analysis reveals that the epistemological relationships are not always dependent on the metaphysical relationships, contrary to what has been assumed by many philosophers of science. Moreover, we identify several importantly different ways that scientific models instantiate these relationships. We argue that our framework provides novel insights concerning the nature of models, explanation, idealization, and understanding. (shrink)

Part of what makes the environment valuable is its autonomy. There are some who think that any human influence on an environment is necessarily autonomy-compromising because it is a form of human control. In this article, I will assume human influence on the environment necessarily undermines autonomy. However, I will argue, even given this assumption, it is still possible for the intervention to enable autonomy in the long run. My focus is on genetic intervention into organisms, because some might think (...) human influence in these cases cannot dissipate. I argue this is mistaken and, borrowing a concept from botany, I argue genes, even genes inserted into a genome by humans, can “naturalize.” Furthermore, they can function in ways that are autonomy-enabling to the individual and to the system to which the organism belongs.

Speech unfolds over time, and the cues for even a single phoneme are rarely available simultaneously. Consequently, to recognize a single phoneme, listeners must integrate material over several hundred milliseconds. Prior work contrasts two accounts: (a) a memory buffer account in which listeners accumulate auditory information in memory and only access higher level representations (i.e., lexical representations) when sufficient information has arrived; and (b) an immediate integration scheme in which lexical representations can be partially activated on the basis of early (...) cues and then updated when more information arises. These studies have uniformly shown evidence for immediate integration for a variety of phonetic distinctions. We attempted to extend this to fricatives, a class of speech sounds which requires not only temporal integration of asynchronous cues (the frication, followed by the formant transitions 150–350 ms later), but also integration across different frequency bands and compensation for contextual factors like coarticulation. Eye movements in the visual world paradigm showed clear evidence for a memory buffer. Results were replicated in five experiments, ruling out methodological factors and tying the release of the buffer to the onset of the vowel. These findings support a general auditory account for speech by suggesting that the acoustic nature of particular speech sounds may have large effects on how they are processed. It also has major implications for theories of auditory and speech perception by raising the possibility of an encapsulated memory buffer in early auditory processing. (shrink)

Can one still have understanding in situations that involve the kind of epistemic luck that undermines knowledge? Kvanvig (The value of knowledge and the pursuit of understanding, 2003; in: Haddock A, Miller A, Pritchard D (eds) Epistemic value, 2009a; in: Haddock A, Miller A, Pritchard D (eds) Epistemic value, 2009b) says yes, Prichard (Grazer Philos Stud 77:325–339, 2008; in: O’Hear A (ed) Epistemology, 2009; in: Pritchard D, Millar A, Haddock A (eds) The nature and value of knowledge: three investigations, 2010) (...) say sometimes, DePaul and Grimm (Philos Phenomenol Res 74:498–514, 2007) and Grimm (Br J Philos Sci 57:515–535, 2006; in: Bernecker S, Pritchard D (eds) The Routledge companion to epistemology, 2011), Kvanvig’s critics, say no. The cases put forth by Kvanvig’s critics share a common feature, which seems to drive the intuition that understanding can’t be lucky: the fact that the information that makes up the individual’s understanding comes exclusively from a bad source. I formulate a case that lacks this feature, drawing on the fact that understanding produced from scientific inquiry is often produced by collaboration. I argue that my case provides good evidence that understanding is not a species of knowledge. (shrink)

Many environmental ethicists think evolutionary processes are good or, put differently, that they are morally valuable. Furthermore, many claim this value can be compromised when humans disrupt or cause a break in these processes. In this paper, I argue this account is mistaken. Evolution is not good. Furthermore, evolution cannot be “broken” by mere human involvement. There is no preordained trajectory in evolution; randomness, genetic drift, and historical contingency influence all evolutionary histories. Additionally, to think humans necessarily undermine so-called “natural” (...) processes and turn them artificial is to ignore Vogel (2011, 2015), and insist on pre-Darwinian dualism. There is no morally meaningful distinction between natural selection and artificial selection; they are both simply selection. Furthermore, animals shape their own evolutionary trajectories, their progenies’, and those of other organisms through their intentions and choices—as is illustrated in the theory of niche construction. Human involvement in evolutionary processes does not “break” them nor does it necessarily reduce the value of the end products of those processes. (shrink)

We argue that the de-extinction of the mammoth cannot be ethically grounded by duties to the extinct mammoth, to ecosystem health or to individual organisms in ecosystems missing the mammoth. However, the action can be shown to be morally permissible via the goods it will afford humans, including advances in scientific knowledge, valuable experiences of awe and pleasure, and perhaps improvements to our moral character or behaviour—if and only if suffering is minimal. Finally, we call for empirical research into how (...) the possibility of the technology affects our behaviour or our character to help the debate transcend duelling intuitions. (shrink)

Some conservation biologists invoke the concept of ‘genetic integrity,’ which they generally assume is a good worth preserving without explicit justification. We examine the question of whether or not there is a prima facie duty to preserve genetic integrity in conservation biology. We examine several possible justifications for the potential duty found in the conservation biology literature. We argue, contra a dominant trend of thought in conservation biology, that there is no prima facie duty to preserve genetic integrity and that (...) any moral obligation to preserve genetic integrity in specific cases is merely derivative of other possible duties.

Each year, over 200 million people are infected with the malaria parasite, nearly half a million of whom succumb to the disease. Emerging genetic technologies could, in theory, eliminate the burden of malaria throughout the world by intentionally eradicating the mosquitoes that transmit the disease. In this paper, we offer an ethical examination of the intentional eradication of Anopheles gambiae, the main malaria vector of sub-Saharan Africa. In our evaluation, we focus on two main considerations: the benefit of alleviating the (...) malaria burden, and the loss of value that would accompany the eradication of the species. We outline a typology of the different ways in which species are valued or could be valuable, then use that typology to appraise the value of the species in question. We argue that Anopheles gambiae has minor (and redundant) instrumental value, little final subjective value and no objective final value. (shrink)

In this article I argue that humans have a pro tanto duty to cognitively enhance some animals threatened with extinction. I will use as a case study a particular set of animals: smaller Australian marsupials. Many of these animals are on the brink of extinction thanks to the introduction of the fox and the domestic cat to the continent of Australia. Ecologists conjecture that these marsupials do not have the behavioural flexibility to cope with these introduced predators. By introducing predators, (...) humans performed a wrong action because it led to the extinction of species and continues to threaten many marsupials species such as woylies, Gilbert's potoroos, numbats and mountain pygmy possums. This wrong action gives rise to an obligation to intervene to prevent further species loss. Traditional means of conservation do not seem sufficient to address this obligation; therefore, there is a duty to cognitively enhance these creatures as soon as the technology is sufficiently researched and safe.

Game theory has played a critical role in elucidating the evolutionary origins of social behavior. Sober and Wilson model altruism as a prisoner's dilemma and claim that this model indicates that altruism arose from group selection pressures. Sober and Wilson also suggest that the prisoner's dilemma model can be used to characterize punishment; hence, punishment too originated from group selection pressures. However, empirical evidence suggests that a group selection model of the origins of altruistic punishment may be insufficient. I argue (...) that examining dominance hierarchies and coalition formation in chimpanzee societies suggests that the origins of altruistic punishment may be best captured by individual selection models. I suggest that this shows the necessity of coupling of game-theoretic models with a conception of what our actual social structure may have been like to best model the origins of our own behavior. ‡I would like to thank Zachary Ernst and Emma Marris for their many helpful comments which greatly improved this paper. †To contact the author, please write to: Department of Philosophy, University of Maryland, Skinner Building, College Park, MD 20742; e-mail: [email protected].

In this paper, we argue that rather than exclusively focusing on trying to determine if an idealized model fits a particular account of scientific explanation, philosophers of science should also work on directly analyzing various explanatory schemas that reveal the steps and justification involved in scientists’ use of highly idealized models to formulate explanations. We develop our alternative methodology by analyzing historically important cases of idealized statistical modeling that use a three-step explanatory schema involving idealization, mathematical operation, and explanatory interpretation.

In response to earlier papers in Informal Logic by Robert Fogelin and Andrew Lugg, this paper explores the issue of whether disagreement could ever be so deep that it defied rational resolution. Contra Lugg, I agree with Fogelin that such unresolvable disagreement is possible and, contra Fogelin, I suggest that the focus of such disagreement can be quite Iimited-a single proposition rather than a whole system of beliefs. I also suggest that emphasising arguing as a human practice rather than arguments (...) as a structure of propositions is unhelpful to consideration of these issues. (shrink)

A recent fMRI study by Webb et al. (Cortical networks involved in visual awareness independent of visual attention, Proc Natl Acad Sci U S A 2016;113:13923–28) proposes a new method for finding the neural correlates of awareness by matching atten- tion across awareness conditions. The experimental design, however, seems at odds with known features of attention. We highlight logical and methodological points that are critical when trying to disentangle attention and awareness.

The concept of explanation is central to scientific practice. However, scientists explain phenomena in very different ways. That is, there are many different kinds of explanation; e.g. causal, mechanistic, statistical, or equilibrium explanations. In light of the myriad kinds of explanation identified in the literature, most philosophers of science have adopted some kind of explanatory pluralism. While pluralism about explanation seems plausible, it faces a dilemma Explanation beyond causation, Oxford University Press, Oxford, pp 39–56, 2018). Either there is nothing that (...) unifies all instances of scientific explanation that makes them count as explanations, or there is some set of unifying features, which seems incompatible with explanatory pluralism. Different philosophers have adopted different horns of this dilemma. Some argue that no unified account of explanation is possible. Others suggest that there is a set of necessary features that can unify all explanations under a single account Explanation beyond causation, Oxford University Press, Oxford, pp 74–95, 2018; Strevens in Depth: an account of scientific explanation, Harvard University Press, Cambridge, 2008). In this paper, we argue that none of the features identified by existing accounts of explanation are necessary for all explanations. However, we argue that a unified account can still be provided that accommodates pluralism. This can be accomplished, we argue, by reconceiving of scientific explanation as a cluster concept: there are multiple subsets of features that are sufficient for providing an explanation, but no single feature is necessary for all explanations. Reconceiving of explanation as a cluster concept not only accounts for the diversity of kinds of explanations, but also accounts for the widespread disagreement in the explanation literature and enables explanatory pluralism to avoid Pincock’s dilemma.

Through an analysis of key themes in Heidegger's work, the book challenges the traditional theological appropriation of Heidegger and the usual characterizations of religious thinking in terms of faith or belief in, or experience of, some ultimate reality. Heidegger, it is argued, offers a unique approach to a variety of issues and problems in contemporary religious thought and philosophy of religion that results in understanding religious thinking as a resolute openness to the holiness and meaningfulness of the world.

In a recent paper in this journal, Jim Garrison (1997) opines that a Deweyan social constructivism ought to be embraced by science educators in preference to the subjectivist variety espoused by Ernst von Glasersfeld as it '. . . retains all [of the latter's] virtues and does not get caught up in its confusions' (p. 543), In this response, I argue that key elements of Garrison's complaints are misguided and that his preferred Deweyan social constructivism is a theoretical framework without (...) apparent superiority and with enough flaws that it is best eschewed by science educators (and metascientists, generally). © 2000 Kluwer Academic Publishers.
