Steven Pinker has said that one of the most important questions humans can ask of themselves is whether moral progress has occurred or is likely to occur. Buchanan and Powell here address that question, in order to provide the first naturalistic, empirically-informed and analytically sophisticated theory of moral progress--explaining the capacities in the human brain that allow for it, the role of the environment, and how contingent and fragile moral progress can be.

Enactivists frequently argue their account heralds a revolution in cognitive science: enactivism will unseat cognitivism as the dominant paradigm. We examine the lines of reasoning enactivists employ in stirring revolt, but show that none of these prove compelling reasons for cognitivism to be replaced by enactivism. First, we examine the hard sell of enactivism: enactivism reveals a critical explanatory gap at the heart of cognitivism. We show that enactivism does not meet the requirements to incite a paradigm shift in the (...) Kuhnian sense—there is no internal crisis in cognitivism. Nor does it provide inherently better explanations of cognition as some have claimed. Second, we consider the soft sell of enactivism: enactivism provides a more attractive, parsimonious, or clear-eyed lens on cognition. This move proves to boil down to a misunderstanding of how theories are selected in science. Instead we lend support to a broader and more desirable way to conceive of enactivism, the recent proposal that enactivism is a philosophy of nature. We explain how a philosophy of nature does more than support a single research paradigm by integrating scientific questions into a cohesive picture. (shrink)

This paper considers a new problem for desire theories of well-being. The problem claims that these theories are implausible because they misvalue the effects of fleeting desires, long-standing desires, and fluctuations in desire strength on well-being. I begin by investigating a version of the desire theory of well-being, simple concurrentism, that fails to capture intuitions in these cases. I then argue that desire theories of well-being that are suitably stability-adjusted can avoid this problem. These theories claim that the average strength (...) of a desire, and the length of time that it is held, both influence the extent to which its fulfilment or frustration affects well-being. I end by considering whether value-fulfilment theories of well-being have a more attractive response to this problem. I find that these theories have significant downsides that make them unappealing alternatives. (shrink)

This article demonstrates that non-mechanistic, dynamical explanations are a viable approach to explanation in the special sciences. The claim that dynamical models can be explanatory without reference to mechanisms has previously been met with three lines of criticism from mechanists: the causal relevance concern, the genuine laws concern, and the charge of predictivism. I argue, however, that these mechanist criticisms fail to defeat non-mechanistic, dynamical explanation. Using the examples of Haken et al.’s model of bimanual coordination, and Thelen et al.’s (...) dynamical field model of infant perseverative reaching, I show how each mechanist criticism fails once the standards of Woodward’s interventionist framework are applied to dynamical models. An even-handed application of Woodwardian interventionism reveals that dynamical models are capable of producing genuine explanations without appealing to underlying mechanistic details. 1Introduction2Interventionism and Mechanistic Explanation 2.1Causal relevance and ideal interventions2.2Invariance2.3Explanation3Covering-Laws and Dynamical Explanation 3.1Dynamical models3.2Covering-law explanation3.3Prediction4Causal Relevance 4.1The causal relevance concern4.2Intervening on dynamical models4.3Test case I: The Haken–Kelso–Bunz model4.4Test case II: Dynamical field model5Genuine Laws 5.1The genuine laws concern5.2Using invariance in place of laws5.3Test case I: The Haken–Kelso–Bunz model5.4Test case II: Dynamical field model6Prediction 6.1Predictivism6.2Crude and invariant prediction7Interventionist Criticism of the Haken–Kelso–Bunz Model8Dynamical Explanation8Conclusion.

One of Russell's most important and interesting books which reconciles the materialistic tendency of psychology with the anti-materialistic tendency of physics.

Desire theories of well-being claim that how well our life goes for us is solely determined by the fulfilment and frustration of our desires. Several writers have argued that these theories are incorrect because they fail to capture the harms of self-sacrifice and severe depression. In this paper, I argue that desire theories of well-being can account for the harm of both phenomena by rejecting proportionalism about desire and motivation. This is the view that desires always motivate proportionally to their (...) strength. If we reject this view, then we can explain the harm of many cases of self-sacrifice as arising when we act upon our weaker desires and thereby frustrate our stronger desires. Moreover, the harm of many cases of severe depression can be explained by its suppression of the motivational force of desires. This inevitably frustrates desires that we are left unmotivated to fulfil. I argue that this approach captures the experiential quality of self-sacrifice and severe depression better than rival views that seek to problematise these phenomena for desire theories of well-being. Moreover, these theories have sufficient conceptual resources to account for residual cases of self-sacrifice and severe depression that are less well explained by this approach. (shrink)

Mechanistic explanations are often said to explain because they reveal the causal structure of the world. Conversely, dynamical models supposedly lack explanatory power because they do not describe causal structure. The only way for dynamical models to produce causal explanations is via the 3M criterion: the model must be mapped onto a mechanism. This framing of the situation has become the received view around the viability of dynamical explanation. In this paper, I argue against this position and show that dynamical (...) models can themselves reveal causal structure and consequently produce nonmechanistic, dynamical explanations. Taking the example of cell fates from systems biology, I show how dynamical models, and specifically the attractor landscapes they describe, identify the causes of cell differentiation and explain why cells select particular fates. These dynamical features of the system better fit Woodward’s (2010, 2018) criteria of specificity and proportionality and make them the best candidate causes of cell fates than mechanisms. I also show how these causes are irreducible and inaccessible to mechanistic models, making 3M unworkable and counterproductive in this case. Dynamical models can reveal dynamical causes and thereby provide causal explanations. (shrink)

This book explores the rise of theoretical physics in 19th century Germany. The authors show how the junior second physicist in German universities over time became the theoretical physicist, of equal standing to the experimental physicist. Gustav Kirchhoff, Hermann von Helmholtz, and Max Planck are among the great German theoretical physicists whose work and career are examined in this book. Physics was then the only natural science in which theoretical work developed into a major teaching and research specialty in its (...) own right. Readers will discover how German physicists arrived at a well-defined field of theoretical physics with well understood and generally accepted goals and needs. The authors explain the nature of the work of theoretical physics with many examples, taking care always to locate the research within the workplace. The book is a revised and shortened version of Intellectual Mastery of Nature: Theoretical Physics from Ohm to Einstein, a two-volume work by the same authors. This new edition represents a reformulation of the larger work. It retains what is most important in the original work, while including new material, sharpening discussions, and making the research more accessible to readers. It presents a thorough examination of a seminal era in physics. (shrink)

Fried and Kollár constructed a fully faithful functor from the category of graphs to the category of fields. We give a new construction of such a functor and use it to resolve a longstanding open problem in computable model theory, by showing that for every nontrivial countable structure${\cal S}$, there exists a countable field${\cal F}$of arbitrary characteristic with the same essential computable-model-theoretic properties as${\cal S}$. Along the way, we develop a new “computable category theory”, and prove that our functor and (...) its partially defined inverse are computable functors. (shrink)

In this paper we examine how the use of robots in caring for elders can impact the meaningfulness of elders’ lives. We present a framework for understanding ‘meaningfulness in life’, and then apply that framework in discussing ways in which the use of robots to assist in activities of daily living can preserve, enhance or undermine the meaningfulness of elders’ lives. We conclude with a discussion of if and how having false beliefs about companion robots can affect meaningfulness in the (...) life of the person having those false beliefs. (shrink)

Any workable ideal of deliberative democracy that includes elections will need modern democracy's ever-present ally, parties. Since the primary function of parties is to win office rather than to reflect on public questions, parties are potential problems for the deliberative enterprise. They are more at home in aggregative models of democracy than in deliberative models. While deliberative democracy will need its moments of aggregation—and therefore, must have parties—partisans as they actually arise in the political world possess traits that undermine the (...) deliberative ideal. If partisans of partisanship are to be unembarrassed by (or are to correct) these defects, even workable ideals of deliberative democracy need to stand at some distance from the partisan imperative.

`Mr Russell's very brilliant criticism of Leibniz ... is a piece of controversial philosophy as well as a contribution to history.' - Bernard Bosanquet.

The proper role, if any, for religion-based arguments is a live and sometimes heated issue within the field of bioethics. The issue attracts heat primarily because bioethical analyses influence the outcomes of controversial court cases and help shape legislation in sensitive biopolicy areas. A problem for religious bioethicists who seek to influence biopolicy is that there is now widespread academic and public acceptance, at least within liberal democracies, that the state should not base its policies on any particular religion’s metaphysical (...) claims or esoteric moral system. In response, bioethicists motivated by religious concerns have adopted two identifiable strategies. Sometimes they rely on slippery-slope arguments that, sometimes at least, have empirically testable premises. A more questionable response is the manipulation and misuse of secular-sounding moral language, such as references to “human dignity,” and the plights of groups of people labeled “vulnerable.”.

Mechanistic explanations, according to one prominent account, are derived from objective explanations (Craver 2007, 2014 ). Mechanistic standards of explanation are in turn pulled from nature, and are thereby insulated from the values of investigators, since explanation is an objectively defined achievement grounded in the causal structure of the world (Craver 2014 ). This results in the closure of mechanism’s explanatory standards—it is insulated from the values, norms and goals of investigators. I raise two problems with this position. First, it (...) relies on several ontological claims which, while plausible, fail to guarantee the objectivity of mechanistic explanatory standards to the degree of certainty required. Second, Craver’s position itself introduces a value–laden explanatory standard—the 3M requirement (Kaplan & Craver 2011 )—which undermines the closure of explanatory standards. I show how in practice mechanistic explanation is in part guided by explanatory taste, shorthand for background contextual values that influence our standards of explanation. Mechanism often has a particular pragmatically-oriented taste for control, and gerrymanders explanatory standards in order to obtain it. I conclude by arguing that objectivity, rather than being obtained through the right set of explanatory standards, is better thought of as the result of processes of intersubjective criticism, which renders visible the contextual values of communities of investigators and allows them to be controlled for (Longino 1990 ).

Many philosophers invoke the "wisdom of nature" in arguing for varying degrees of caution in the development and use of genetic enhancement technologies. Because they view natural selection as akin to a master engineer that creates functionally and morally optimal design, these authors tend to regard genetic intervention with suspicion. In Part II, we examine and ultimately reject the evolutionary assumptions that underlie the master engineer analogy (MEA). By highlighting the constraints on ordinary unassisted evolution, we show how intentional genetic (...) modification can overcome many of the natural impediments to the human good. Our contention is that genetic engineering offers a solution that is more eff icient, reliable, versatile, and morally palatable than the lumbering juggernaut of Darwinian evolution. In Part III, we evaluate a recent attempt to ground precautionary enhancement heuristics in adaptive etiology. Our problem with this approach is two-fold: first, it is based on the same "strong adaptationist" interpretation of evolution that motivates the flawed MEA, and second, the etiological concept of function on which it relies provides indirect and potentially misleading information about the likely consequences of genetic intervention. We offer instead enhancement criteria based on causal relationships in ontogeny. We conclude that rather than grounding a presumption against deliberate genetic modification, the causal structure of the living world gives us good moral reason to pursue it. (shrink)

While its tone is playful and frivolous, this book poses tough questions over the nature of religion and belief. Religion provides comfortable responses to the questions that have always beset humankind - why are we here, what is the point of being alive, how ought we to behave? Russell snatches that comfort away, leaving us instead with other, more troublesome alternatives: responsibility, autonomy, self-awareness. He tells us that the time to live is now, the place to live is here, (...) and the way to be happy is to ensure others are happy. (shrink)

'A scientific opinion is one which there is some reason to believe is true; an unscientific opinion is one which is held for some reason other than its probable truth.' - Bertrand Russell One of Russell's most important books, this early classic on science illuminates his thinking on the promise and threat of scientific progress. Russell considers three questions fundamental to an understanding of science: the nature and scope of scientific knowledge, the increased power over nature that (...) science affords, and the changes in the lives of human beings that result from new forms of science. With customary wit and clarity, Russell offers brilliant discussions of many major scientific figures, including Aristotle, Galileo, Newton and Darwin.

Russell's classic examination of the relation between individual experience and the general body of scientific knowledge. It is a rigorous examination of the problems of an empiricist epistemology.

Stephen Jay Gould argued that replaying the “tape of life” would result in a radically different evolutionary outcome. Some biologists and philosophers, however, have pointed to convergent evolution as evidence for robust replicability in macroevolution. These authors interpret homoplasy, or the independent origination of similar biological forms, as evidence for the power of natural selection to guide form toward certain morphological attractors, notwithstanding the diversionary tendencies of drift and the constraints of phylogenetic inertia. In this paper, I consider the implications (...) of homoplasy for the debate over the nature of macroevolution. I argue that once the concepts of contingency and convergence are fleshed out, it becomes clear that many instances of homoplasy fail to negate Gould’s overarching thesis, and may in fact support a Gouldian view of life. My argument rests on the distinction between parallelism and convergence, which I defend against a recent challenge from developmental biology. I conclude that despite the difficulties in defining and identifying parallelism, the concept remains useful and relevant to the contingency controversy insofar as it underscores the common developmental origins of iterated evolution.

The debate over whether we should believe that mathematical objects exist quickly leads to the question of how to determine what we should believe. Indispensabilists claim that we should believe in the existence of mathematical objects because of their ineliminable roles in scientific theory. Eleatics argue that only objects with causal properties exist. Mark Colyvan’s recent defenses of Quine’s indispensability argument against some contemporary eleatics attempt to provide reasons to favor the indispensabilist’s criterion. I show that Colyvan’s argument is not (...) decisive against the eleatic and sketch a way to capture the important intuitions behind both views. (shrink)

Liberal proponents of genetic engineering maintain that developing human germline modification technologies is morally desirable because it will result in a net improvement in human health and well-being. Skeptics of germline modification, in contrast, fear evolutionary harms that could flow from intervening in the human germline, and worry that such programs, even if well intentioned, could lead to a recapitulation of the scientifically and morally discredited projects of the old eugenics. Some bioconservatives have appealed as well to the value of (...) retaining our “given” human biological nature as a reason for restraining the development and use of human genetic modification technologies even where they would tend to increase well-being. In this article, I argue that germline intervention will be necessary merely to sustain the levels of genetic health that we presently enjoy for future generations—a goal that should appeal to bioliberals and bioconservatives alike. This is due to the population-genetic consequences of relaxed selection pressures in human populations caused by the increasing efficacy and availability of conventional medicine. This heterodox conclusion, which I present as a problem of intergenerational justice, has been overlooked in medicine and bioethics due to certain misconceptions about human evolution, which I attempt to rectify, as well as the sordid history of Darwinian approaches to medicine and social policy, which I distinguish from the present argument.

The key to human nature that Marx found in wealth and Freud in sex, Bertrand Russell finds in power. Power, he argues, is man's ultimate goal, and is, in its many guises, the single most important element in the development of any society. Writting in the late 1930s when Europe was being torn apart by extremist ideologies and the world was on the brink of war, Russell set out to found a 'new science' to make sense of the (...) traumatic events of the day and explain those that would follow. The result was Power , a remarkable book that Russell regarded as one of the most important of his long career. Countering the totalitarian desire to dominate, Russell shows how political enlightenment and human understanding can lead to peace - his book is a passionate call for independence of mind and a celebration of the instinctive joy of human life.

Philosophy students often struggle to master the complex skills needed to succeed in their work, especially in writing thesis-driven essays. Research over the past forty years on instructional scaffolding, both generally and as applied in philosophy, has helped teachers to refine both instruction and assignment design to improve students’ performance on complex philosophical tasks. This essay reviews the fundamentals of scaffolding in order to motivate and support some innovative in-class exercises and writing assignments that can help students develop even finer-grained (...) skills. These skills are useful both intrinsically and for their transfer to longer-form essays, to other philosophical work, and to the general academic and intellectual development of our students.

Philosophy proceeds, supposedly, by way of rational inquiry and argument, yet, as Jonathan Glover has written, “philosophers persistently disagree” to such an extent that the “apparent lack of clear progress or of a body of established results is an embarrassment”. To outside observers, this may appear puzzling. Even professional philosophers sometimes worry about their discipline’s lack of consensus, continuing disagreement on standards and methods, and increasingly fragmented, hyperspecialized state of play. Though philosophy hesitates to speak with one voice, it can (...) endorse and teach values to do with intellectual rigor and honesty, charity to opponents, and openness to evidence. If these are passed down effectively from teachers to students, we might hope that philosophers will bring their characteristic skills and values to some of the great practical questions of our age, not least those relating to global injustice and risks to humanity’s future. All too often, the debates that surround these questions are dominated by tribalism, dogma, and emotional manipulation. With dedication, and perhaps a bit of good luck, philosophical training might provide something of a corrective. If philosophy fails in that respect by not living up to its ideals, that’s a situation we can identify and try to alter. (shrink)

A number of authors have pointed to “convergent evolution” as evidence for the central role of natural selection in shaping predictable trajectories of macroevolution. However, there are numerous conceptual and empirical difficulties that arise in broadly appealing to the frequency of homoplasy as evidence for a non-contingently constrained adaptational design space. Most important is the need to distinguish between convergent (externally constrained) and parallel (internally constrained) evolution, and to consider how the respective frequencies of these significantly different sources of homoplasy (...) affect a strong adaptationist view of life. In this paper, I critically evaluate Simon Conway Morris’s use of the homoplasy literature to support his argument for a non-contingent, counterfactually stable account of macroevolutionary pattern. In so doing, I offer a conception of parallelism which avoids the charge that it differs from convergence merely in degree and not in kind. I argue that although organisms sharing a homoplastic trait will also share varying degrees of homology, it is the underlying developmental homology with respect to the generators directly causally responsible for the homoplastic event that defines parallel evolution and non-arbitrarily distinguishes it from convergence. The notion of “screening-off” is used to distinguish the proximal generators of a homoplastic trait from its more distal genetic causes (such as a master control gene). (shrink)

In “On the Life of thinking in Aristotle’s De Anima,” the author offers an interpretation of the tripartite structure of the unified soul in Aristotle’s text. The principleactivity that unities the nutritive, sensuously perceptive and noetically perceptive parts of the soul into a single, continuous entity is shown by our author to be genesis (or the sexual begetting of offspring). After establishing this observation, the paper provides the textual grounds to understand how both sensuous and noetic perception can be understood (...) as a kind of embodied genesis. A further consequence of this argument will be an interpretation of “thinking,” of noetic perception, as a kind of open and passive reception of the primary forms of other beings. As such, Aristotle’s conception of thinking, qua nous, is a refreshing, if strange, contrast to the more common modern vision of “thinking” as the activity of an agent mentally seizing hold of beings in the service of the mastery of nature.

Habermas asserts that the ‘presupposition’ of the common objective world is thrust upon us by the pragmatics of language use. However, this is a dubious claim. A pre-linguistic relation to the world as common and objective is required for language acquisition. What’s more, Husserl’s analyses indicate that aspects of our experience of the common world are grounded in experiences of spatio-temporal horizonality and of the co-presence of others within that world-horizon. This is not to negate the importance of communicatively achieved (...) intersubjectivity, nor to diminish the rational significance of our linguistically articulated ‘world concepts’. But it is to suggest that the ‘presupposition’ of the common objective world has phenomenological, not linguistic-pragmatic, roots. (shrink)
