Throughout the last quarter of the nineteenth century, researchers became increasingly interested in explaining the ways in which mammalian teeth, especially molars, and their complex arrangements of cusps arose along both developmental and evolutionary timescales. By the 1890s, two theories garnered special prominence; the tritubercular theory and the concrescence theory. The tritubercular theory was proposed by Edward Drinker Cope in 1883, and later expanded by Henry Fairfield Osborn in 1888, while the concrescence theory was developed by Carl Röse (...) in 1892. Reviews concerning the evolution of mammalian molar teeth tended to paint the two theories as occupying opposing sides, and debates arose between their main proponents; however, their tenets do not seem logically incompatible. Throughout this paper, I argue that the conflict that arose was due not to the content of the theories, but to a diverse array of commitments Cope, Osborn, and Röse held, which turned into background assumptions within the setting of these theories. This history traces the context in which Cope, Osborn, and Röse developed the tritubercular and concrescence theories, and the ways in which the assumptions that these investigators held influenced their perceptions of their theories.

ABSTRACT Our ascriptions of content to past utterances assign to them a level of conceptual continuity and determinacy that extends beyond what could be grounded in the usage up to their time of utterance. If one accepts such ascriptions, one can argue either that future use must be added to the grounding base, or that such cases show that meaning is not, ultimately, grounded in use. The following will defend the first option as the more promising of the two, though (...) this ultimately requires understanding the relation between use and meaning as ‘normative’ in two important ways. The first way is that the function from use to meaning must be of a sort that allows us to maintain a robust distinction between actual and correct use. The second sort of normativity is unique to theories that extend the grounding base into the future. In particular, if meaning is partially a function of future use, we can see our commitment to the ‘determinacy’ of meaning as a practical commitment that structures our linguistic practices rather than a theoretical commitment that merely describes them.

I analyze the epistemic strategies used by paleontologists (between 1830–1930) to reconstruct features of ancient organisms from fossilized bodies and footprints by presenting two heuristics: (1) a “claim of harmony” which posits the harmonious interaction of natural objects in order for complex systems to be simplified and (2) the “kintsugi heuristic” which is used inter-theoretically to explore new claims of harmony. I apply these to three successive historical cases: Georges Cuvier’s laws of correlation, the panpsychist paleontology of Edward Drinker (...) Cope, and the single-character approach of Henry Fairfield Osborn. (shrink)

A new research programme conceives of consciousness as a natural kind. One proposed virtue of this approach is that it can help resolve the methodological puzzle of consciousness, which involves distinguishing consciousness from cognitive access. The present article raises a novel problem for this approach. The problem is rooted in the fact that there may be episodes of conscious experience that have not been classified as such. I argue that conceiving of consciousness as a natural kind cannot distinguish consciousness from (...) cognitive access. (shrink)

We investigate under what conditions contrary-to-duty (CTD) structures lacking temporal and action elements can be given a coherent reading. We argue, contrary to some recent proposals, that CTD is not an instance of defeasible reasoning, and that methods of nonmonotonic logics are inadequate since they are unable to distinguish between defeasibility and violation of primary obligations. We propose a semantic framework based on the idea that primary and CTD obligations are obligations of different kinds: a CTD obligation pertains to, or (...) pre-supposes, a certain context in which a primary obligation is already violated. This framework is presented initially as an extension of Standard Deontic Logic (SDL), a normal modal logic of type KD, and is illustrated by application to a series of examples. The concluding section is concerned with some resemblances between CTD and defeasible reasoning. We show first that the SDL-based framework contains a flaw and must be adjusted. A discussion of possible adjustments, including an alternative treatment in terms of a preference-based semantics, reveals difficulties that are reminiscent of problems in defeasible reasoning and intensional accounts of defeasible conditionals.

One of the most influential of the Victorian philosophers, Henry Sidgwick also made important contributions to fields such as economics, political theory and classics. A proponent of the utilitarianism of Jeremy Bentham and John Stuart Mill, which he analysed in his classic work The Methods of Ethics , he later turned to the practical side of politics in this work, published in 1891. His aim was to have a 'rational discussion of political questions in modern states', and he offers (...) a thorough examination of Victorian politics, beginning with a discussion of political theory before moving on to more concrete matters such as property and law. The later chapters discuss the function of government through themes such as procedural matters, international affairs, war, political parties, and public participation, giving a comprehensive account of both ideas about and the functioning of late-nineteenth-century government.

CHAPTER I GENERAL ACCOUNT OF THE SUBJECT THERE is some difficulty in defining the subject of Ethics in a manner which can fairly claim general acceptance ...

The Ancient Greeks understood both art and technology (techne) as imitation (mimesis) of Nature (physis). This article argues that the rapidly growing ecological innovation strategy known as biomimicry makes it possible for technology to leave behind the modern goal of “mastering and possessing” Nature and instead to rediscover the initial vocation it shared with art: imitating Nature. This in turn suggests a general strategy for philosophical inquiry into the biomimetic principle of “Nature as model”: the transposition of philosophical analyses of (...) concepts associated primarily with poetics and related fields—mimesis, mimicry, translation, analogy, metaphor, etc.—into the philosophy of biomimicry.

After the terrorist attacks of September 11, 2001, most legacy airlines filed for bankruptcy protection as a way to cut costs drastically, with the exception of American Airlines. This article applies the Principle of Double-Effect to the act of filing for Chapter 11 bankruptcy protection for reasons of management strategy, in particular, cost-cutting. It argues that the Principle can be a useful tool for discerning the ethicality of the action, and demonstrates the usefulness by proposing three double-effect criteria that, when (...) fulfilled, argues for the ethical justifiability the action in question.

Raz's method is as unusual, and as admirable, as the substance of his sometimes rather unfortunately labeled "perfectionist liberalism"—unfortunate because "it is not perfectionist in the more ordinary sense of the term" in that it recognizes that "imperfect ways of life may be the best which is possible for people" and "is strongly pluralistic", while understanding its fundamental value of well-being as the active and autonomous making of a life of one's own. Raz's approach is simultaneously alert to the complexity (...) of argument, to a degree that practitioners of practical ethics sometimes are not, and aware of the limits of theorizing, as devotees of theoretical ethics rarely are. Thus, while scorning "supermarket liberalism" and rejecting, in company with Rawls, "hand-to-mouth piecemeal intuitionism", Raz also doubts whether ideal theory in the Rawlsian mode is "a meaningful enterprise", emphasizing wisely, in my judgment, that "not everything we know can be exhaustively stated in the abstract". The "dense webs of complex actions and interactions" that give meaning to our lives "defy explicit learning or comprehensive articulation. They are available only to those who have or can acquire practical knowledge of them, that is, knowledge embodied in social practices and transmitted by habituation". (shrink)

This is an exploration of what Locke and Whately said about the Argumentatum ad Hominem, especially in the context of what they said about the other ad arguments, and with a view to ascertaining whether what they said lends support to the understanding of this argument implicit in Johnstone's thesis that all valid philosophical arguments are ad hominem. It is concluded that this support is forthcoming insofar as Locke and Whately had in mind an argument concerned with principles.The essay ends (...) with a brief reformulation of Johnstone's generalization regarding philosophical arguments.

This brief, but tightly argued, work advances a dual thesis: Kant’s compatibilist solution to the free will problem is best understood in terms of Davidson’s anomalous monism; so understood, it constitutes a viable position, defensible in contemporary terms. The text consists of a short introduction followed by four substantive chapters dealing, respectively, with: Kant’s theory of compatibilism ; Kant and contemporary metaphysics ; Kant’s theory of causal determinism ; and Kant’s theory of free will. Because of the range of topics (...) covered and the thoroughness of its argumentation, this book should be of interest not only to Kantians, but to philosophers concerned with the more general issues regarding compatibilism.

Supererogation is the theory that some acts go beyond the call of duty. They are praiseworthy, but their omission is not blameworthy. Notice that supererogation has to do with praise and blame as well as with what is a duty or morally obligatory. Moral duty requires a moral system on the basis of which duty or obligation is assigned. Utilitarianism can provide a criterion of moral obligation, and it can also provide a criterion for moral praise and blame. However, there (...) is no necessity that the utilitarian criteria for praise and blame should be precisely correlated with its criteria of the morally obligatory and permissible. (shrink)

The thesis is two-fold: to show that to be human is to have a nature disposed to inalienable conflict of interests, and to show that creativity is the best principle by which to organize interests.

This book’s basic argument is that the Freudian unconscious, far from constituting a radical break with the philosophy of consciousness, is merely the latest exemplar in a heritage of philosophical misunderstanding of the Cartesian cogito that interprets “I think, therefore I am” as “I represent myself, therefore I am” (in the classic interpretation of Heidegger, one of the targets of the book).

ObjectiveHead and neck cancer treatments are known to significantly affect functionality and appearance, leading to an increased risk for body image disturbances. Yet, few longitudinal studies exist to examine body image in these patients. Based on a conceptual model, the current study aimed to determine, in patients newly diagnosed with HNC: the prevalence, level, and course of body image concerns; correlates of upon cancer diagnosis body image concerns; predictors of immediate post-treatment body image concerns; and association between body image concerns (...) and levels of anxiety, depression, suicidal ideation, support, and alcohol and drug misuse.MethodsTwo hundred and twenty-three, newly diagnosed with a primary HNC were assessed using structured clinical interviews and psychometric measures at three, and 6 months after diagnosis. Primary outcome was 3-month, as it was most salient to body image disturbance. Multiple linear regression analyses were conducted on the potential body image predictors, based on the model.ResultsSixty-eight percent of patients with HNC presented some level of body image concerns. Body image concerns at baseline and post-treatment were significantly related and significantly increased from pre- to post-treatment. Immediately post-treatment, 89% presented some level of body image concerns. Correlates of body image concerns in patients with HNC at baseline included: physical symptom burden, difficulties with communication and eating, coping with the cancer diagnosis using denial, suicidal ideation, and having had a past anxiety diagnosis. When controlling for sociodemographic and medical variables, body image concerns in patients with HNC in the immediate post-treatment were predicted by: baseline body image, physical symptom burden, and neuroticism.ConclusionThis longitudinal study helps identify patients more susceptible to experience body image disturbance following head and neck cancer. Clinicians ought to pay special attention to body image concerns upon cancer diagnosis, physical symptom burden, and neuroticism, and may want to target these factors in future preventive interventions.

Supposing that talk of a distinctively artistic type of value is warranted, what separates it from other sorts of value? Any plausible answer must explain both what is of value and what is artistic about artistically valuable properties. Flaws with extant accounts stem from neglect of one component or the other; the account offered here, based on careful attention to actual art-critical practices, brings both together. The “value” component depends on the capacity of artworks to provide subjectively valuable experiences, while (...) the “artistic” component relies on the specific norms constitutive of artworld institutions. Understanding artistic value in this way allows for progress on several persistent problems, including the ethical value of art, relativism in artistic value, and the proper boundaries of philosophical aesthetics.

Despite the spectacular contributions to knowledge made by molecular biology during the last half century, cancer research has not delivered an agreed explanation of how malignant tumours originate. The models assiduously investigated in molecular terms largely reflect waves of fashion, and time has revealed their inadequacy: cancer is (1) not caused by the direct action of oncogenes, (2) not fully explained by the impairment of tumour suppressor genes, (3) not set in motion by mutations controlling the cell cycle, (4) not (...) governed by the dependence of malignant tumours on an adequate blood supply and (5) not triggered by a failure of programmed cell death. But there is now strong evidence that cancers may have their origin in mutations that block the execution of critical steps in the process of normal differentiation. Cancer, thus seen, is not initially a disease of cell multiplication, but a disease of differentiation. The evidence for this point of view should now be explored.
