To date, no definition of life has been unequivocally accepted by the scientific community. In frustration, some authors advocate alternatives to standard definitions. These include using a list of characteristic features, focusing on life’s effects, or categorizing biospheres rather than life itself; treating life as a fuzzy category, a process or a cluster of contingent properties; or advocating a ‘wait-and-see’ approach until other examples of life are created or discovered. But these skeptical, operational, and pluralistic approaches have intensified the debate, (...) rather than settled it. Given the failure of even these approaches, we advocate a new strategy. In this paper, we reverse the usual line of reasoning and argue that the “life problem” arises from thinking incorrectly about the nature of life. Scientists most often conceptualize life as a class or kind, with earthly life as a single instance of it. Instead, we advocate thinking about Earth’s Life as an individual, in the way that species are now thought to be. In this view, Life is a monophyletic clade that originated with a last universal common ancestor, and includes all its descendants. We can continue to use the category ‘life’ pragmatically to refer to similarities between various phenomena and Life. But the relevant similarities are a matter of interest and preference, not a matter of fact. The search for other life in the Universe, then, is merely a search for entities that resemble parts of Life in whatever sense astrobiologists find most appealing. This does not mean that the search for evolved complexity elsewhere in the universe or its creation in the lab are futile endeavors, but that debates over whether they count as ‘life’ are. Ironically, finally abandoning the concept ‘life’ may make our searches for evolved complexity more fruitful. We explain why. (shrink)

This paper contributes to the study of paracompleteness and paraconsistency. We present two logics that address the following questions in novel ways. How can the paracomplete theorist characterize the formulas that defy excluded middle while maintaining that not all formulas are of this kind? How can the paraconsistent theorist characterize the formulas that obey explosion while still maintaining that there are some formulas not of this kind?

Unlike the overall framework of Ernest Nagel's work on reduction, his theory of intertheoretic connection still has life in it. It handles aptly cases where reduction requires complex representation of a target domain. Abandoning his formulation as too liberal was a mistake. Arguments that it is too liberal at best touch only Nagel's deductivist theory of explanation, not his condition of connectability. Taking this condition seriously gives a powerful view of reduction, but one which requires us to index explanatory power (...) to sciences as they are formulated at particular times. While we may thereby reduce more than philosophers have supposed, we must abandon hope (as Nagel did) of saying anything useful about reductionism. (shrink)

According to recently influential conceptions of public reasoning, citizens have the right to demand of each other ‘public justifications’ for controversial political action. On this view, only arguments that all reasonable citizens can affirm from within their diverse ethical standpoints can count as legitimate justifications for political action. Both proponents and critics often assume that the case for this expectation derives from the special justificatory burden created by the systematically coercive character of political action. This paper challenges that assumption. While (...) conceding that citizens who propose to deploy the coercive apparatus of the state to enforce controversial legislation owe their fellows a justification that overcomes the strong presumption against coercing agents, it denies that this consideration can explain why public justifications are also required. Having argued that the public justification requirement is not among the justification conditions for public coercion, the paper then proposes an alternative rationale for the expectation that political action be publicly justified. On this alternative, the case for the public justification requirement depends on democratic citizens’ standing as legislative co-authors, and not on considerations having to do with their liability as private individuals to coercion at the hands of the state.

Recently something close to a consensus about the best way to naturalize the notion of biological function appears to be emerging. Nonetheless, teleological notions in biology remain controversial. In this paper we provide a naturalistic analysis for the notion of natural design. Many authors assume that natural design should be assimilated directly to function. Others find the notion problematic because it suggests that evolution is a directed process. We argue that both of these views are mistaken. Our naturalistic account does (...) not simply equate design with function. We argue that the distinction between function and design is important for understanding the evolution of the physical and behavioral traits of organisms. (shrink)

Bioethics at the Movies explores the ways in which popular films engage basic bioethical concepts and concerns. Twenty philosophically grounded essays use cinematic tools such as character and plot development, scene-setting, and narrative-framing to demonstrate a range of principles and topics in contemporary medical ethics. The first section plumbs popular and bioethical thought on birth, abortion, genetic selection, and personhood through several films, including The Cider House Rules, Citizen Ruth, Gattaca, and I, Robot. In the second section, the contributors examine (...) medical practice and troubling questions about the quality and commodification of life by way of Dirty Pretty Things, Eternal Sunshine of the Spotless Mind, and other movies. The third section's essays use Million Dollar Baby, Critical Care, Big Fish, and Soylent Green to show how the medical profession and society at large view issues related to aging, death, and dying. A final section makes use of Extreme Measures and select Spanish and Japanese films to discuss two foundational matters in bioethics: the role of theories and principles in medicine and the importance of cultural context in devising care. Structured to mirror bioethics and cinema classes, this innovative work includes end-of-chapter questions for further consideration and contributions from scholars from the United States, Canada, the United Kingdom, Israel, Spain, and Australia.

By an argument form I shall mean a schema consisting of a string of symbols that are place-­‐holders for either logical terms or non-­‐logical (descriptive/content) terms: substituting terms of the appropriate kind for the symbols yields an argument. A substitution instance of an argument form is an argument that arises as a result of such a substitution. By a valid argument I shall mean an argument such that it is impossible for the premises to be true and the conclusion false. (...) Thus, an invalid argument is an argument such that it is possible for the premises to be true and the conclusion false. (shrink)

This paper is about the underlying logical principles of scientific theories. In particular, it concerns ex contradictione quodlibet (ECQ) the principle that anything follows from a contradiction. ECQ is valid according to classical logic, but invalid according to paraconsistent logics. Some advocates of paraconsistency claim that there are ‘real’ inconsistent theories that do not erupt with completely indiscriminate, absurd commitments. They take this as evidence in favor of paraconsistency. Michael (2016) calls this the non-triviality strategy (NTS). He argues that this (...) strategy fails in its purpose. I will show that Michael's criticism significantly over-reaches. The fundamental problem is that he places more of a burden on the advocate of paraconsistency than on the advocate of classical logic. The weaknesses in Michael's argument are symptomatic of this preferential treatment of one viewpoint in the debate over another. He does, however, make important observations that allow us to clarify some of the complexities involved in giving a logical reconstruction of a theory. I will argue that there are abductive arguments deserving of further consideration for the claim that paraconsistent logic offers the best explanation of the practice of inconsistent science. In this sense, the debate is still very much open. (shrink)

The Quine/Putnam indispensability argument is regarded by many as the chief argument for the existence of platonic objects. We argue that this argument cannot establish what its proponents intend. The form of our argument is simple. Suppose indispensability to science is the only good reason for believing in the existence of platonic objects. Either the dispensability of mathematical objects to science can be demonstrated and, hence, there is no good reason for believing in the existence of platonic objects, or their (...) dispensability cannot be demonstrated and, hence, there is no good reason for believing in the existence of mathematical objects which are genuinely platonic. Therefore, indispensability, whether true or false, does not support platonism. Mathematical platonists claim that at least some of the objects which are the subject matter of pure mathematics (e.g. numbers, sets, groups) actually exist. Furthermore, they claim that these objects differ radically from the concrete objects (trees, cats, stars, molecules) which inhabit the material world. We take the standard platonistic position to include the claim that platonic objects lack spatio-temporal location and causal powers. Many (perhaps most) mathematical platonists subscribe to this view.1 But some who call themselves (or might be called) mathematical platonists.. (shrink)

It is widely believed that medically inert treatments (“placebos”) can bring about therapeutic benefits. There is also evidence that medically active treatments may also have “placebo” effects. Since anything that has the potential to benefit patients ought to be exploited, subject to appropriate ethical standards, it has been suggested that more should be done to investigate and exploit the power of the placebo for therapeutic benefit. I explore the acute epistemic and ethical constraints that such exploitation is likely to face, (...) and conclude that effective exploitation is unlikely. (shrink)

It has been much debated whether Tractarian objects are what Russell would have called particulars or whether they include also properties and relations. This paper claims that the debate is misguided: there is no logical category such that Wittgenstein intended the reader of the Tractatus to understand his objects either as providing examples of or as not providing examples of that category. This is not to say that Wittgenstein set himself against the very idea of a logical category: quite the (...) contrary. However, where Russell presents his logical variety of particulars and the various types of universal, and Frege presents his of objects and the various types of function, Wittgenstein denies the propriety of such a priori expositions. Wittgenstein envisages a variety of logical types of entity but insists that the nature of these types is something to be discovered only through analysis. (shrink)

Foucault is one of the most widely cited thinkers across social sciences and humanities disciplines today. Foucault’s appeal, and ongoing value, across the disciplines has much to do with the power of his thought and his method to help us see the contingency of practices we take to be inevitable. It is argued in this introductory article that Foucault’s emphasis on contingency is as misunderstood as it is influential. I distinguish two senses of contingency in Foucault. A first sense, widely (...) acknowledged, concerns Foucault’s facility at showing that a taken-for-natural practice is in fact contingently produced. A second sense, widely neglected, concerns the facility of Foucauldian methods for grasping how a given practice was contingently produced. The second sense of contingency opens up possibilities for practical transformation that the former sense of contingency largely leaves to the side. (shrink)

According to standard mathematical platonism, mathematical entities (numbers, sets, etc.) are abstract entities. As such, they lack causal powers and spatio-temporal location. Platonists owe us an account of how we acquire knowledge of this inaccessible mathematical realm. Some recent versions of mathematical platonism postulate a plenitude of mathematical entities, and Mark Balaguer has argued that, given the existence of such a plenitude, the attainment of mathematical knowledge is rendered non-problematic. I assess his epistemology for such a profligate platonism and find (...) it unsatisfactory because it lacks an adequate semantics, in particular, an adequate account of reference. (shrink)

Social play is naturally characterized in intentional terms. An evolutionary account of social play could help scientists to understand the evolution of cognition and intentionality. Alexander Rosenberg (1990) has argued that if play is characterized intentionally or functionally, it is not a behavioral phenotype suitable for evolutionary explanation. If he is right, his arguments would threaten many projects in cognitive ethology. We argue that Rosenberg's arguments are unsound and that intentionally and functionally characterized phenotypes are a proper domain for ethological (...) investigation. (shrink)

According to mathematical platonism, mathematical entities (e.g. numbers) exist as abstract objects. If numbers are abstract objects, then I doubt our ability to know of their existence.objects lack causal powers and spatio-temporal location. On the other hand, we human knowers exist within the causal nexus and are wholly spatio-temporal. So our epistemic isolation from abstract objects is total and unbridgeable (Benacerraf 1973, Cheyne 2001). Any version of mathematical platonism that is worth taking seriously must claim that we can and do (...) know of the existence of abstract objects. Since I deny that knowledge of the existence of abstract objects is possible, I reject mathematical platonism. (shrink)

This article utilizes the case of Ms H. to examine the contrasting ways that surrogate decision makers move from simply hearing information about the patient to actually knowing and understanding the patient’s medical condition. The focus of the case is on a family’s request to actually see the patient’s wounds instead of being told about the wounds, and the role of clinical ethicists in facilitating this request. We argue that clinical ethicists have an important role to play in the work (...) of converting information into knowledge and that this can serve as a valuable way forward in the midst of seemingly intractable conflicts in the medical setting.

Frege's strict alignment between his syntactic and ontological categories is not, as is commonly assumed, some kind of a philosophical thesis. There is no thesis that proper names refer only to objects, say, or that what refers to an object is a proper name. Rather, the alignment of categories is internal to Frege's conception of what syntax and ontology are. To understand this, we need to recognise the pride of place Frege assigns within his theorising to the notion of truth. (...) For both language and the world, the Fregean categories are logical categories, categories, that is, of truth. The elaboration of this point makes clear the incoherence of supposing that they might not align. (shrink)

William James’s moral and political thought was remarkably well adapted to its historical context, in particular to the emergence in the late nineteenth century of a generalized culture of uncertainty, contingency, and probability that called into question traditional conceptions of sovereign selfhood and autonomous freedom. Facing the solidification of numerous apparatus of chance, James developed a strenuous ethics rooted in a conception of freedom as self-transformation. That this ethics was attuned to the pressing problematics of his day is shown by (...) sideways glances at his contemporaries Edith Wharton, William Dean Howells, Charles Sanders Peirce, Josiah Royce, as well as then-emergent forms of everydayness such as personal health insurance. Such an ethics remains a valuable source of freedom today insofar as we remain bound to chance as an ongoing problematic conditioning our moral possibilities. (shrink)

Immanuel Kant: The Very Idea of a Critique of Pure Reason is a study of the background, development, exposition, and justification of Kant's Critique of Pure Reason. Instead of examining Kant's arguments for the transcendental ideality of space and time, his deduction of the pure concepts of the understanding, or his account of the dialectic of human reason, J. Colin McQuillan focuses on Kant's conception of critique. By surveying the different ways the concept of critique was used during the (...) eighteenth century, the relationship between Kant's critique and his pre-critical experiments with different approaches to metaphysics, the varying definitions of a critique of pure reason Kant offers in the prefaces and introductions to the first Critique, and the way Kant responds to objections, McQuillan is able to highlight an aspect of Kant's critical philosophy that is too often overlooked—the reason that philosophy is critical.

Millikan's account of concepts is applicable to questions about concepts in nonhuman animals. I raise three questions in this context: (1) Does classical conditioning entail the possession of simple concepts? (2) Are movement property concepts more basic than substance concepts? (3) What is the empirical content of claiming that concept meanings do not necessarily change as dispositions change?

The issue of plagiarism—claiming credit for work that is not one’s own, rightly, continues to cause concern in the academic community. An analysis is presented that shows the effects that may arise from metrics-based assessments of research, when credit for an author’s outputs (chiefly publications) is given to an institution that did not support the research but which subsequently employs the author. The incentives for what is termed here “institutional plagiarism” are demonstrated with reference to the UK Research Assessment Exercise (...) in which submitting units of assessment are shown in some instances to derive around twice the credit for papers produced elsewhere by new recruits, compared to papers produced ‘in-house’.

This article enumerates several different possible construals of the idea that religion is owed respect. It asks: 1. how religion might be an object of respect; 2. what sorts of respect religion might command; and 3. whose respect might be at stake in complaints about and demands for religious recognition. By distinguishing various ways in which these questions can be interpreted, the discussion aims to introduce some clarity to a notoriously controversial and knotty area of public discussion. Although the article (...) does not propose any particular answer to the question ‘Does religion deserve our respect?’, it does urge that theorists give greater attention to the neglected way in which religions have a ‘public presence’ that engenders distinctive sorts of social respect. I suggest that the popularity among academic political theorists and philosophers of a ‘liberal’ paradigm emphasising the importance of freedom of conscience and ‘respect for persons’ has led them to ignore the implications of ‘public presence’ for debates over the place of religion in modern secular societies.

Contemporary theories of civic education frequently appeal to an ideal of mutual respect in the context of ethical, ethical and religious disagreement. This paper critically examines two recently popular criticisms of this ideal. The first, coming from a postmodern direction, charges that the ideal is hypocritical in its effort to be maximally impartial and fair. The second, which I associate with such 'new atheists' as Sam Harris and Richard Dawkins, argues that notions of mutual respect pose a threat to such (...) basic goals of education as the cultivation of critical thinking.

Nanotechnology thrives in the realm of the virtual.
