Abstract: The thesis of underdetermination of theory by evidence has led to an opposition between realism and relationism in philosophy of science. Various forms of the thesis are examined, and it is concluded that it is true in at least a weak form that brings realism into doubt. Realists therefore need, among other things, a theory of degrees of confirmation to support rational theory choice. Recent such theories due to Glymour and Friedman are examined, and it is argued that their criterion of "unification" for good theories is better formulated in Bayesian terms. Bayesian confirmation does, however, have consequences that tell against realism. It is concluded that the prospects are dim for scientific realism as usually understood.

Publisher's Note: A danger of a heavily formalist approach to the structure of science is that it may lose sight of the concrete actualities on which scientific inference is exercised. On the other hand, and excessively descriptive and relativist approach fails to achieve a general systematization of models of inference. This book tries to steer a middle course between these extremes. Hesse first discusses some epistemological problems bequeathed by positivists analyses of science and also considers the problem of inductive justification of theories in relation to evidence. Following Keynes and Carnap she argues that the axioms of probability constitute the best postulate system for a logic of confirmation.

Summary: In this book Hesse argues, contra Duhem, that models and analogies are integral to understanding scientific practice in general and scientific advancement in particular, especially how the domain of a scientific theory is extended and how theories generate genuinely novel predictions. Hesse thinks that, in order help us to understand a new system or phenomenon, we will often create an analogical model that compares this new system or phenomenon with a more familiar system or phenomenon. Hesse distinguishes different types of analogies according to the kinds of similarity relations in which two objects enter: Positive analogies, negative analogies, and neutral analogies. The crux of the argument is that the recognition of similarities of meaning between paired terms and the recognition of similar causal relations within two analogies plays an essential role in theoretical explanation and prediction in science.

Summary: In this article Hesse defends the idea that scientific theories are hypothetico-deductive in form. She examines this hypothetico-deductive method by considering some examples from nineteenth-century mathematical physics. By means of these examples she brings out two points about scientific hypothesis. The first is that mathematical formalisms, when used as hypotheses in the description of physical phenomena, may function like the mechanical models of an earlier stage in physics, without having in themselves any mechanical or other physical interpret. The second point is that most physicists do not regard models as literal descriptions of nature, but as standing in a relation of analogy to nature.

Introduction: For over three decades, a handful of partially true assumptions were permitted to shape the construction of general evolutionary theories about sexual selection. These theories of sexual selection presupposed the existence of a highly discriminating, exually 'coy' female who was courted by sexually undiscriminating males. Work by female primatologists undermined these assumptions.

Abstract: The orthodox approach to the environment and its inhabitants is deemed to be anthropocentric in that it recognises the moral standing of human beings alone, and as such other beings are given at the most indirect moral consideration when their interests conflict with the interests of humans. However, many global environmental problems and worldwide practices directly affect not just human beings but many other creatures too. In the light of this, the anthropocentric approach has been accused by some philosophers of being too narrowly focused on human interests to creditably account for the true extent of our moral obligations. This article provides a conceptual outline of biocentrism as an alternative approach to ethics; one which widens the moral scope to include all living beings as candidates deserving of moral consideration. The article also discusses how this approach might be applied to contemporary ethical issues which are international in their dimension, including environmental issues, as well as issues concerning our use of animals in worldwide human practices.

Abstract: In the light of the current environmental crisis, different approaches to mitigating climate change have been put forward, some more plausible than others. However, despite problems with anthropocentric approaches to global warming (whether these be weak or strong versions of the approach), it seems that because of the largely anthropocentric outlook of the Western world, an internationally united approach to mitigating climate change will (perhaps inevitably) come from human-centred values. But what are the long-term implications of this? Such values need to be at the very least challenged if we are interested in providing justifiable and sustainable solutions to the current crisis. Indeed, this paper will analyse sentientism as an alternative environmental ethic stance and will discuss why it provides a more plausible approach than anthropocentric ones whilst recognising where it falls short.

Abstract: The considerable conservation research on environmental problems and climate change tends to focus on species “biodiversity” rather than individuals. Individuals of the same species get categorized as “wild” or “captive”, with the latter often omitted from conservationists’ concerns. But wild and captive animals, although they may require different treatment, have comparable interests as individuals. Equity requires taking this into account in conservation efforts.

Abstract: I defend the view that we should not overintellectualize the mind. Nonhuman animals can occupy islands of practical rationality: they can have contextbound reasons for action even though they lack full conceptual abilities. Holism and the possibility of mistake are required for such reasons to be the agent's reasons, but these requirements can be met in the absence of inferential promiscuity. Empirical work with animals is used to illustrate the possibility that reasons for action could be bound to symbolic or social contexts, and connections are made to simulationist accounts of cognitive skills.

Introduction: Quantum mechanics is, at least at first glance and at least in part, a mathematical machine for predicting the behaviors of microscopic particles - or, at least, of the measuring instruments we use to explore those behaviors - and in that capacity, it is spectacularly successful: in terms of power and precision, head and shoulders above any theory we have ever had. Mathematically, the theory is well understood; we know what its parts are, how they are put together, and why, in the mechanical sense (i.e., in a sense that can be answered by describing the internal grinding of gear against gear), the whole thing performs the way it does, how the information that gets fed in at one end is converted into what comes out the other. The question of what kind of a world it describes, however, is controversial; there is very little agreement, among physicists and among philosophers, about what the world is like according to quantum mechanics. Minimally interpreted, the theory describes a set of facts about the way the microscopic world impinges on the macroscopic one, how it affects our measuring instruments, described in everyday language or the language of classical mechanics. Disagreement centers on the question of what a microscopic world, which affects our apparatuses in the prescribed manner, is, or even could be, like intrinsically; or how those apparatuses could themselves be built out of microscopic parts of the sort the theory describes.
