Summary: In this paper Beebee argues that the problem of induction, which she describes as a genuine sceptical problem, is the same for Humeans than for Necessitarians. Neither scientific essentialists nor Armstrong can solve the problem of induction by appealing to IBE (Inference to the Best Explanation), for both arguments take an illicit inductive step.
How scientific models can explain
Abstract: Scientific models invariably involve some degree of idealization, abstraction, or fictionalization of their target system. Nonetheless, I argue that there are circumstances under which such false models can offer genuine scientific explanations. After reviewing three different proposals in the literature for how models can explain, I shall introduce a more general account of what I call model explanations, which specify the conditions under which models can be counted as explanatory. I shall illustrate this new framework by applying it to the case of Bohr’s model of the atom, and conclude by drawing some distinctions between phenomenological models, explanatory models, and fictional models.
A critique of Methodological Naturalism
Abstract: Larry Laudan defends “methodological naturalism” – the position that scientific methodology can be fully empirical and be subject to radical change without sacrificing the rationality of science. This view has two main components: (a) the historical claim that just as substantive science has changed and developed in response to new information and evidence, so have the basic rules and methods which guide theory appraisal in science changed in response to new information about the world; and (b) the philosophical claim that all aspects of science are in principle subject to radical change and evolution in the light of new information about the world. In this paper, the athor argues that one main historical example used by Laudan, namely, the scientific revolution that accompanied the change from the corpuscular to the wave theory of light, does not in fact support the view that there have been radical methodological changes in the history of science.
Epistemology in The Age of Neuroscience
Comment: Churchland argues that advances in neuroscience should should bring about reform in a number of central areas of philosophy. Formal logic does not model human reasoning, formal semantics cannot account for how human language is meaningful, there are no foundations of knowledge, there is no a priori knowledge, and true belief is not a goal of human nervous systems.
Biosemantics
Summary: The term ‘biosemantics’ has usually been applied only to the theory of mental representation. This article first characterizes a more general class of theories called ‘teleological theories of mental content’ of which biosemantics is an example. Then it discusses the details that distinguish biosemantics from other naturalistic teleological theories. Naturalistic theories of mental representation attempt to explain, in terms designed to fit within the natural sciences, what it is about a mental representation that makes it represent something. Frequently these theories have been classified as either picture theories, causal or covariation theories, information theories, functionalist or causal-role theories, or teleological theories, the assumption being that these various categories are side by side with one another.
In Defense of Proper Functions
Abstract: I defend the historical definition of “function” originally given in my Language, Thought and Other Biological Categories (1984a). The definition was not offered in the spirit of conceptual analysis but is more akin to a theoretical definition of “function”. A major theme is that nonhistorical analyses of “function” fail to deal adequately with items that are not capable of performing their functions.
Natural Selection as a Population-Level Causal Process
Abstract: Recent discussions in the philosophy of biology have brought into question some fundamental assumptions regarding evolutionary processes, natural selection in particular. Some authors argue that natural selection is nothing but a population-level, statistical consequence of lower-level events (Matthen and Ariew [2002]; Walsh et al. [2002]). On this view, natural selection itself does not involve forces. Other authors reject this purely statistical, population-level account for an individual-level, causal account of natural selection (Bouchard and Rosenberg [2004]). I argue that each of these positions is right in one way, but wrong in another; natural selection indeed takes place at the level of populations, but it is a causal process nonetheless.
On three theories of implicature: default theory, relevance and minimalism
Abstract: Grice’s distinction between what is said by a sentence and what is implicated by an utterance of it is both extremely familiar and almost universally accepted. However, in recent literature, the precise account he offered of implicature recovery has been questioned and alternative accounts have emerged. In this paper, I examine three such alternative accounts. My main aim is to show that the two most popular accounts in the current literature (the default inference view and the relevance theoretic approach) still face signifi cant problems. I will then conclude by suggesting that an alternative account, emerging from semantic minimalism, is best placed to accommodate Grice’s distinction.
Knowledge of Arithmetic
Abstract: The goal of the research programme I describe in this article is a realist epistemology for arithmetic which respects arithmetic’s special epistemic status (the status usually described as a prioricity) yet accommodates naturalistic concerns by remaining funda- mentally empiricist. I argue that the central claims which would allow us to develop such an epistemology are (i) that arithmetical truths are known through an examination of our arithmetical concepts; (ii) that (at least our basic) arithmetical concepts are accurate mental representations of elements of the arithmetical structure of the inde- pendent world; (iii) that (ii) obtains in virtue of the normal functioning of our sensory apparatus. The first of these claims protects arithmetic’s special epistemic status relative, for example, to the laws of physics, the second preserves the independence of arithmetical truth, and the third ensures that we remain empiricists.
The Enduring Appeal of Natural Theological Arguments
Abstract: Natural theology is the branch of theology and philosophy that attempts to gain knowledge of God through non-revealed sources. In a narrower sense, natural theology is the discipline that presents rational arguments for the existence of God. Given that these arguments rarely directly persuade those who are not convinced by their conclusions, why do they enjoy an enduring appeal? This article examines two reasons for the continuing popularity of natural theological arguments: (i) they appeal to intuitions that humans robustly hold and that emerge early in cognitive development; (ii) they serve an argumen- tative function by presenting particular religious views as live options. I conclude with observations on the role of natural theology in contemporary analytic philosophy of religion.
