No other scientific theory has had as tremendous an impact on our understanding of the world as Darwin's theory as outlined in his Origin of Species, yet from the very beginning the theory has been subject to controversy. The Evolution of Darwinism focuses on three issues of debate - the nature of selection, the nature and scope of adaptation, and the question of evolutionary progress. It traces the varying interpretations to which these issues were subjected from the beginning and the (...) fierce contemporary debates that still rage on and explores their implications for the greatest questions of all: Where we come from, who we are and where we might be heading. Written in a clear and non-technical style, this book will be of use as a textbook for students in the philosophy of science who need to become familiar with the background to the debates about evolution.

Thanks to its brilliant melding of film noir, science fiction, and cyberpunk motifs, not to mention its stirring music and unprecedented visual density, Ridley Scott’s Blade Runner (1982/2007) has become an influential cultural icon. What really sets the film apart from most movies, however, are the ways in which it encourages philosophical questions. Virtually all commentators agree that “What does it mean to be human?” – understood as asking something like “What characterizes the real (or authentic) human being?” – is (...) the central philosophical question the film raises. Attempting to answer that question can be a fertile approach to the film, with moral implications for how to think about the qualifications for inclusion in the human community. That is not, however, the only way to appreciate the philosophical significance of Blade Runner. The film also encourages viewers to ponder the question, “What fundamental experiences constitute the uniquely human mode of self-consciousness?” Showing how the latter question leads to a richer appreciation of Blade Runner as philosophy is the aim of this chapter.

THERE IS WIDESPREAD AGREEMENT among historians that the writings of Robert Boyle (1697-1691) constitute a valuable archive for understanding the concerns of seventeenth-century British natural philosophers. His writings have often been seen as representing, in one fashion or another, all of the leading intellectual currents of his day. ~ There is somewhat less consensus, however, on the proper historiographic method for interpreting these writings, as well as on the specific details of the beliefs expressed in them. Studies seeking to explicate (...) Boyle's thought have been, roughly speaking, of two general sorts. On the one hand there are those studies of a broadly "intellectualist" orientation which situate his natural philosophy within the intellectual context provided by metaphysics, religion, and early modern science. In this connection his corpuscularianism has been shown to be motivated by specific epistemological, theological, as well as empirical concerns. One of the central aims of such studies has been to show that apparently discordant elements in his scientific thought are rendered coherent by referring them to such "non-scientific" commitments. Among studies of this sort might be mentioned the works of John Hedley Brooke, E. A. Burtt, Gary B. Deason, J. E. McGuire, R. Hooykaas, Robert H. Kargon, Eugene M. Klaaren, P. M. Rattansi, and Richard S. Westfall. (shrink)

In recent years philosophers have attempted to clarify the units of selection controversy in evolutionary biology by offering conceptual analyses of the term 'unit of selection'. A common feature of many of these analyses is an emphasis on the claim that units of selection are entities exhibiting heritable variation in fitness. In this paper I argue that the demand that units of selection be characterized in terms of heritability is unnecessary, as well as undesirable, on historical, theoretical, and philosophical grounds. (...) I propose a positive account of the proper referent of the term 'unit of selection', distinguishing between the processes of evolution and phenotypic selection. The main result of this analysis is greater clarity about the conceptual structure of evolutionary theory. (shrink)

In an influential paper, Stephen Jay Gould and Richard Lewontin contrasted selection-driven adaptation with phylogenetic, architectural, and developmental constraints as distinct causes of phenotypic evolution. In subsequent publications Gould has elaborated this distinction into one between a narrow “Darwinian Fundamentalist” emphasis on “external functionalist” processes, and a more inclusive “pluralist” emphasis on “internal structuralist” principles. Although theoretical integration of functionalist and structuralist explanations is the ultimate aim, natural selection and internal constraints are treated as distinct causes of evolutionary change. This (...) distinction is now routinely taken for granted in the literature in evolutionary biology. I argue that this distinction is problematic because the effects attributed to non-selective constraints are more parsimoniously explained as the ordinary effects of selection itself. Although it may still be a useful shorthand to speak of phylogenetic, architectural, and developmental constraints on phenotypic evolution, it is important to understand that such “constraints” do not constitute an alternative set of causes of evolutionary change. The result of this analysis is a clearer understanding of the relationship between adaptation, selection and constraints as explanatory concepts in evolutionary theory. (shrink)

Darwinian evolutionary biology has often been criticized for appealing to the notion of 'chance' in its explanations. According to some critics, such appeals exhibit the explanatory poverty of evolutionary theory. In response, defenders of Darwinism sometimes downplay the importance of 'chance' in evolution. I believe that both of these approaches are mistaken. The main thesis of this paper is that the term 'chance' encompasses a number of distinct concepts, and that at least some of these concepts serve essential explanatory functions (...) in evolutionary biology. This claim is defended by way of an historical survey of the major concepts of 'chance' in the history of evolutionary biology, especially the concepts used by Jean Baptiste Lamarck, Charles Darwin, and Sewall Wright. An examination of their biologies shows how the concepts of 'chance' used cohere with their major scientific objectives and methods. These concepts survive and continue to function as important explanatory factors in contemporary evolutionary biology. Examples of such usage are given, and the explanatory status of 'chance' assessed. (shrink)

THE DANISH chemist and physicist Hans Christian Oersted (1777-I 851) is recognized by historians of science primarily as the discoverer of electromagnetism. His experiments in 1820 demonstrated a definite lawlike relationship between electrical and magnetic phenomena. The quite general question of whether there is in science such a thing as a “logic of discovery” can in this case be given a more precise formulation. Why was Oersted, rather than another of the many scientists interested in electricity and magnetism in the (...) nineteenth century, the fortunate one to have made the discovery, and thus to have his name immortalized in the history of science? What events, ideas, or methods were responsible for the discovery? (shrink)

The concept of ‘phylogenetic inertia’ is routinely deployed in evolutionary biology as an alternative to natural selection for explaining the persistence of characteristics that appear sub-optimal from an adaptationist perspective. However, in many of these contexts the precise meaning of ‘phylogenetic inertia’ and its relationship to selection are far from clear. After tracing the history of the concept of ‘inertia’ in evolutionary biology, I argue that treating phylogenetic inertia and natural selection as alternative explanations is mistaken because phylogenetic inertia is, (...) from a Darwinian point of view, simply an expected effect of selection. Although Darwin did not discuss ‘phylogenetic inertia,’ he did assert the explanatory priority of selection over descent. An analysis of ‘phylogenetic inertia’ provides a perspective from which to assess Darwin’s view. (shrink)

In an important article, Kim Sterelny and Philip Kitcher challenge the common assumption that for any biological phenomenon requiring a selectionist explanation, it is possible to identify a uniquely correct account of the relevant selection process. They argue that selection events can be modeled in any of a number of different, equally correct ways. They call their view ' Pluralism,' and explicitly connect it with various antirealist positions in the philosophy of science. I critically evaluate Sterelny and Kitcher's Pluralism along (...) with its attendant antirealist theses. In particular, I argue that there are serious problems with their pluralistic antirealism regarding units of selection. By correctly diagnosing these problems a more adequate position can be constructed. I defend such a position, which I designate Inclusive Hierarchical Monism, and show how it captures the important virtues of Sterelny and Kitcher's approach while avoiding its problems. (shrink)

In his (1984) John Beatty correctly identifies the issue of the role of chance in evolution as one of the liveliest disputes in evolutionary biology. He argues, on the basis of a carefully articulated example, that "Even on a proper construal of 'natural selection', it is difficult to distinguish between the 'improbable results of natural selection' and evolution by random drift". His other remarks indicate that he is thinking of conceptual as well as practical indistinguishability. In this discussion I take (...) issue with one of the consequences Beatty draws from his example. I argue that the example at most shows that the effects of drift and selection are sometimes difficult to separate in practice, but that the stronger conceptual claim is not warranted. The deeper problems raised by the example are seen to demand causal, rather then conceptual, analysis. (shrink)

In The Advancement of Science (1993) Philip Kitcher develops what he calls the 'Compromise Model' of the closure of scientific debates. The model is designed to acknowledge significant elements from 'Rationalist' and 'Antirationalist' accounts of science, without succumbing to the one-sidedness of either. As part of an ambitious naturalistic account of scientific progress, Kitcher's model succeeds to the extent that transitions in the history of science satisfy its several conditions. I critically evaluate the Compromise Model by identifying its crucial assumptions (...) and by attempting to apply the model to a major transition in the history of biology: the rejection of 'naive group selectionism' in the 1960s. I argue that the weaknesses and limitations of Kitcher's model exemplify general problems facing philosophical models of scientific change, and that recognition of these problems supports a more modest vision of the relationship between historical and philosophical accounts of science.

In philosophy, an argument consists of a set of statements called premises that serve as grounds for affirming another statement called the conclusion. Philosophers typically distinguish arguments in natural languages (such as English) into two fundamentally different types: deductive and inductive. Each type of argument is said to have characteristics that categorically distinguish it from the other type. The two types of argument are also said to be subject to differing evaluative standards. Pointing to paradigmatic examples of each type of (...) argument helps to clarify their key differences. The distinction between the two types of argument may hardly seem worthy of philosophical reflection, as evidenced by the fact that their differences are usually presented as straightforward, such as in many introductory philosophy textbooks. Nonetheless, the question of how best to distinguish deductive from inductive arguments, and indeed whether there is a coherent categorical distinction between them at all, turns out to be considerably more problematic than commonly recognized. This article identifies and discusses a range of different proposals for marking categorical differences between deductive and inductive arguments while highlighting the problems and limitations attending each. Consideration is also given to the ways in which one might do without a distinction between two types of argument by focusing solely on the application of evaluative standards to arguments instead.

Widely acclaimed upon its release as a future classic, Denis Villeneuve’s Blade Runner 2049 is visually stunning, philosophically profound, and a provocative extension of the story in Ridley Scott’s Blade Runner. Containing specially commissioned chapters by a roster of international contributors, this fascinating collection explores philosophical questions that abound in Blade Runner 2049, including: -/- What distinguishes the authentically "human" person? How might natality condition one’s experience of being-in-the-world? How might shared memories feature in the constitution of personal identities? What (...) happens when created beings transcend the limits intended in their design? What (if anything) is it like to be a hologram? Can artificial beings participate in genuinely romantic relationships? How might developing artificial economics impact our behaviour as prosumers? What are the implications of techno-human enhancement in an era of surveillance capitalism? -/- Including a foreword by Denis Villeneuve, Blade Runner 2049: A Philosophical Exploration is essential reading for anyone interested in philosophy, film studies, philosophy of mind, psychology, gender studies, and conceptual issues in cognitive science and artificial intelligence.

Biologists Richard Dawkins and Stephen Jay Gould have recently extended their decades-old disagreements about evolution to the issue of the nature and reality of evolutionary progress. According to Gould, 'progress' is a noxious notion that deserves to be expunged from evolutionary biology. In Dawkins' view, on the other hand, progress is one of the most important, pervasive and inevitable aspects of evolution. Simple appeals to 'the evidence' are clearly insufficient to resolve this disagreement, since it is precisely the interpretation of (...) the evidence that is in dispute. Scientific controversies in general, and the Dawkins/Gould dispute over evolutionary progress in particular, are worth examining in some detail because doing so sheds light on the interconnected roles of methodological and contextual factors in the formation, articulation and defense of scientific claims. My aim in this paper is to clarify the structure of the Dawkins/Gould dispute by analyzing it in terms of a tri-level model of scientific controversies, involving 'top-level' substantive disagreements, 'middle-level' methodological differences, and 'bottom-level' differences in historical and social factors. This simple three-tiered model is sufficiently abstract to have more general applicability to other scientific controversies. (shrink)

Vagueness provides the first comprehensive examination of a topic of increasing importance in metaphysics and the philosophy of logic and language. Timothy Williamson traces the history of this philosophical problem from discussions of the heap paradox in classical Greece to modern formal approaches such as fuzzy logic. He illustrates the problems with views which have taken the position that standard logic and formal semantics do not apply to vague language, and defends the controversial realistic view that vagueness is a (...) kind of ignorance--that there really is a grain of sand whose removal turns a heap into a non-heap, but we cannot know which one it is.

This paper presents a computer model of cortical broadcast and competition based on spiking neurons and inspired by the hypothesis of a global neuronal workspace underlying conscious information processing in the human brain. In the model, the hypothesised workspace is realised by a collection of recurrently inter-connected regions capable of sustaining and disseminating a reverberating spatial pattern of activation. At the same time, the workspace remains susceptible to new patterns arriving from outlying cortical populations. Competition among these cortical populations for (...) influence on the workspace is effected by a combination of mutual inhibition and top-down amplification. (shrink)

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

The paper clarifies and defends the orthodox view that counterfactual conditionals with impossible antecedents are vacuously true against recent criticisms. It argues that apparent counterexamples to orthodoxy result from uncritical reliance on a fallible heuristic used in the processing of conditionals. A comparison is developed between such counterpossibles and vacuously true universal generalizations.

Humean arguments from evil are some of the most powerful arguments against Theism. They take as their data what we know about good and evil. And they argue that some rival to Theism better explains, or otherwise predicts, that data than Theism. However, this paper argues that there are many problems with various methods for defending Humean arguments. I consider Philo’s original strategy; modern strategies in terms of epistemic probability; phenomenological strategies; and strategies that appeal to scientific and metaphysical explanations. (...) None of these methods have been sufficiently developed to provide a clear and distinctive defense of Humean arguments. Defenders of Humean arguments need to spend more time on the underlying methodology of their arguments. (shrink)

The author argues that all forms of life are interconnected and that no being, construct, or object can exist independently from the ecological entanglement, nor does "nature" exist as an entity separate from the uglier or more synthetic elements of life. Realizing this interconnectedness is what the author calls the ecological thought. He investigates the philosophical, political, and aesthetic implications of this interconnectedness.

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

When I take off my glasses, the world looks blurred. When I put them back on, it looks sharpedged. I do not think that the world really was blurred; I know that what changed was my relation to the distant physical objects ahead, not those objects themselves. I am more inclined to believe that the world really is and was sharp-edged. Is that belief any more reasonable than the belief that the world really is and was blurred? I see more (...) accurately with my glasses on than off, so visual appearances when they are on have some cognitive priority over visual appearances when they are off. If I must choose which kind of visual appearance to take at face value, I will choose the sharp-edged look. But what should I think when I see a mist, which looks very blurred however well I am seeing? Indeed, why choose to take any of the looks at face value? Why not regard all the choices as illegitimate projections of ways of seeing the world onto the world itself? (shrink)

Two opposing tendencies in the philosophy of language go by the names of ‘referentialism’ and ‘inferentialism’ respectively. In the crudest version of the contrast, the referentialist account of meaning gives centre stage to the referential semantics for a language, which is then used to explain the inference rules for the language, perhaps as those which preserve truth on that semantics (since a referential semantics for a language determines the truth-conditions of its sentences). By contrast, the inferentialist account of meaning gives (...) centre stage to the inference rules for the language, which are then used to explain its referential semantics, perhaps as the semantics on which the rules preserve truth. On pain of circularity, we cannot combine both directions of explanation. (shrink)

This paper challenges the soundness of the two-dimensional conceivability argument against the derivation of phenomenal truths from physical truths in light of a hyperintensional, ground-theoretic regimentation of the ontology of consciousness. The regimentation demonstrates how ontological dependencies between truths about consciousness and about physics cannot be witnessed by epistemic constraints, when the latter are recorded by the conceivability—i.e., the epistemic possibility—thereof. Generalizations and other aspects of the philosophical significance of the hyperintensional regimentation are further examined.

The fundamental freedoms of speech, conscience, privacy, and religion are now an essential part of the fabric of contemporary society, set down in our most basic laws and regularly invoked in our political and cultural debates. These freedoms play a vital role in securing the spaces and opportunities within which people are able to pursue their own lives in their own ways. Independence of Mind takes this accepted thought a step further, by exploring the ways in which the fundamental freedoms (...) help us to achieve something even more profound, by enabling us to arrive at beliefs, convictions and voices of our own, so that we truly come to think, believe and speak for ourselves in the rich and various ways that the freedoms then protect. Privacy grants us the distance and refuge from others necessary to develop views of our own; freedom of speech calls on us to imagine ways of expressing ourselves that are both true to the views we have developed and innovative in their own right; freedom of conscience enables each of us to create a distinctive rational personality in which to embed the convictions that we wish to treat as non-negotiable; freedom of religion allows groups of us to endorse certain beliefs as articles of faith, free from the full demands of rational scrutiny. Much has been written about the political and legal implications of the fundamental freedoms and their entrenchment in bills of rights. This is the first book to undertake a comprehensive philosophical examination of their moral bases. It offers a penetrating analysis of what makes these particular freedoms matter to us in the ways that they do, and of the true significance of their entrenchment in law. (shrink)

Previous research has suggested that bodily signals from internal organs are associated with diverse cortical and subcortical processes involved in sensory-motor functions, beyond homeostatic reflexes. For instance, a recent study demonstrated that the preparation and execution of voluntary actions, as well as its underlying neural activity, are coupled with the breathing cycle. In the current study, we investigated whether such breathing-action coupling is limited to voluntary motor action or whether it is also present for mental actions not involving any overt (...) bodily movement. To answer this question, we recorded electroencephalography (EEG), electromyography (EMG), and respiratory signals while participants were conducting a voluntary action paradigm including self-initiated motor execution (ME), motor imagery (MI), and visual imagery (VI) tasks. We observed that the voluntary initiation of ME, MI, and VI are similarly coupled with the respiration phase. In addition, EEG analysis revealed the existence of readiness potential (RP) waveforms in all three tasks (i.e., ME, MI, VI), as well as a coupling between the RP amplitude and the respiratory phase. Our findings show that the voluntary initiation of both imagined and overt action is coupled with respiration, and further suggest that the breathing system is involved in preparatory processes of voluntary action by contributing to the temporal decision of when to initiate the action plan, regardless of whether this culminates in overt movements. -/- .

Early practitioners of the social studies of science turned their attention away from questions of institutionalisation, which had tended to emphasize macrolevel explanations, and attended instead to microstudies of laboratory practice. The author is interested in re-investigating certain aspects of institution formation, notably the formation of scientific, medical, and engineering disciplines. He emphasises the manner in which science as cultural practice is imbricated with other forms of social, political, and even aesthetic practices. The author considers the following topics: the organic (...) physics of 1847; the innovative research program of Carl Ludwig as a model for institutionalising science-based medicine, optics, painting, and ideology in Germany, 1845-95; the Haber-Bosch synthesis of ammonia; and the introduction of nuclear magnetic resonance instrumentation into the practice of organic chemistry.
