Summary: In this article Massimi discusses the important role that history and philosophy of science plays or ought to play within philosophy. The aim of the paper is to offer a historical reconstruction and a possible diagnosis of why the long marriage between philosophy and the sciences was eventually wrong after Kant. Massimi examines Kant’s view on philosophy and the sciences, from his early scientific writings to the development of critical philosophy and the pressing epistemological he felt the need to address in response to the sciences of his time.
Experiment, observation and the confirmation of laws
Summary: It is customary to distinguish experimental from purely observational sciences. The former include physics and molecular biology, the latter astronomy and palaeontology. Surprisingly, mainstream philosophy of science has had rather little to say about the observational/experimental distinction. For example, discussions of confirmation usually invoke a notion of ‘evidence’, to be contrasted with ‘theory’ or ‘hypothesis’; the aim is to understand how the evidence bears on the hypothesis. But whether this ‘evidence’ comes from observation or experiment generally plays no role in the discussion; this is true of both traditional and modern confirmation theories, Bayesian and non-Bayesian. In this article, the author sketches one possible explanation, by suggesting that observation and experiment will often differ in their confirmatory power. Based on a simple Bayesian analysis of confirmation, Okasha argues that universal generalizations (or ‘laws’) are typically easier to confirm by experimental intervention than by pure observation. This is not to say that observational confirmation of a law is impossible, which would be flatly untrue. But there is a general reason why confirmation will accrue more easily from experimental data, based on a simple though oft-neglected feature of Bayesian conditionalization.
Models in Physics
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.
On intuitional stability: The clear, the strong and the paradigmatic
Abstract: Skepticism about the epistemic value of intuition in theoretical and philosophical inquiry has recently been bolstered by empirical research suggesting that people’s concrete-case intuitions are vulnerable to irrational biases (e.g., the order effect). What is more, skeptics argue that we have no way to “calibrate” our intuitions against these biases and no way of anticipating intuitional instability. This paper challenges the skeptical position, introducing data from two studies that suggest not only that people’s concrete-case intuitions are often stable, but also that people have introspective awareness of this stability, providing a promising means by which to assess the epistemic value of our intuitions.
Can there be a feminist science?
Abstract: This paper explores a number of recent proposals regarding “feminist science” and rejects a content-based approach in favor of a process-based approach to characterizing feminist science. Philosophy of science can yield models of scientific reasoning that illuminate the interaction between cultural values and ideology and scientific inquiry. While we can use these models to expose masculine and other forms of bias, we can also use them to defend the introduction of assumptions grounded in feminist political values.
The myth of non-reductive materialism
Summary: This article explores the idea that we can assuage our physicalist qualms by embracing “ontological physicalism”, the claim that all that exists in space-time is physical, but, at the same time, accept “property dualism”, a dualism about psychological and physical attributes, insisting that psychological concepts or properties form an irreducible, autonomous domain. The issue the author explores is whether or not a robust physicalist can, consistently and plausibly, swear off reductionism – that is, whether or not a substantial form of physicalism can be combined with the rejection of psycho-physical reduction. The author argues that a middle-of-the road position of the sort just described is not available. More specifically, he claim that a physicalist has only two genuine options, eliminativism and reductionism.
A ctitique of localized realism
Abstract: In an attempt to avert Laudan’s pessimistic induction, Worrall and Psillos introduce a narrower version of scientific realism. According to this version, which can be referred to as “localized realism”, realists need not accept every component in a successful theory. They are supposed only to accept those components that led to the theory’s empirical success. Consequently, realists can avoid believing in dubious entities like the caloric and ether. This paper examines and critiques localized realism. It also scrutinizes Psillos’s historical study of the caloric theory of heat, which is intended to support localized realism.
Dispositions without conditionals
Abstract: Dispositions are modal properties. The standard conception of dispositions holds that each disposition is individuated by its stimulus condition(s) and its manifestation(s), and that their modality is best captured by some conditional construction that relates stimulus to manifestation as antecedent to consequent. In this paper Vetter proposes an alternative conception of dispositions: each disposition is individuated by its manifestation alone, and its modality is closest to that of possibility – a fragile vase, for instance, is one that can break easily. The view is expounded in some detail and defended against the major objections.
Philosophical expertise and scientific expertise
Abstract: The “expertise defense” is the claim that philosophers have special expertise that allows them to resist the biases suggested by the findings of experimental philosophers. Typically, this defense is backed up by an analogy with expertise in science or other academic fields. Recently, however, studies have begun to suggest that philosophers’ intuitions may be just as subject to inappropriate variation as those of the folk. Should we conclude that the expertise defense has been debunked? In this paper, the author argues that the analogy with science still motivates a default assumption of philosophical expertise; however, the expertise so motivated is not expertise in intuition, and its existence would not suffice to answer the experimentalist challenge. She suggests that there are deep parallels between the current methodological crisis in philosophy and the decline of introspection-based methods in psychology in the early twentieth century. The comparison can give us insight into the possible future evolution of philosophical methodology.
Pierre Duhem’s Good Sense as a Guide to Theory Choice
Abstract: This paper examines Duhem’s concept of good sense as an attempt to support a non rule-governed account of rationality in theory choice. Faced with the underdetermination of theory by evidence thesis and the continuity thesis, Duhem tried to account for the ability of scientists to choose theories that continuously grow to a natural classification. The author examines the concept of good sense and the problems that stem from it. The paper presents a recent attempt by David Stump to link good sense to virtue epistemology. It is argued that even though this approach can be useful for the better comprehension of the concept of good sense, there are some substantial differences between virtue epistemologists and Duhem. The athor proposes a possible way to interpret the concept of good sense, which overcomes the noted problems and fits better with Duhem’s views on scientific method and motivation in developing the concept of good sense.
