Abstract: This article examines questions connected with the two features of Locke’s intellectual landscape that are most salient for understanding his philosophy of science: (1) the profound shift underway in disciplinary boundaries, in methodological approaches to understanding the natural world, and in conceptions of induction and scientific knowledge; and (2) the dominant scientific theory of his day, the corpuscular hypothesis. Following the introduction, section 2 addresses questions connected to changing conceptions of scientific knowledge. What does Locke take science (scientia) and scientific knowledge to be generally, why does he think that scientia in natural philosophy is beyond the reach of human beings, and what characterizes the conception of human knowledge in natural philosophy that he develops? Section 3 addresses the question provoked by Locke’s apparently conflicting treatments of the corpuscular hypothesis. Does he accept or defend the corpuscular hypothesis? If not, what is its role in his thought, and what explains its close connection to key theses of the Essay? Since a scholarly debate has arisen about the status of the corpuscular hypothesis for Locke, Section 3 reviews some main positions in that debate. Section 4 considers the relationship between Locke’s thought and that of a figure instrumental to the changing conceptions of scientific knowledge, Isaac Newton
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.
Types and Tokens
Abstract: The distinction between a type and its tokens is a useful metaphysical distinction. In §1 it is explained what it is, and what it is not. Its importance and wide applicability in linguistics, philosophy, science and everyday life are briefly surveyed in §2. Whether types are universals is discussed in §3. §4 discusses some other suggestions for what types are, both generally and specifically. Is a type the sets of its tokens? What exactly is a word, a symphony, a species? §5 asks what a token is. §6 considers the relation between types and their tokens. Do the type and all its tokens share the same properties? Must all the tokens be alike in some or all respects? §7 explains some problems for the view that types exist, and some problems for the view that they don’t. §8 elucidates a distinction often confused with the type-token distinction, that between a type (or token) and an occurrence of it. It also discusses some problems that occurrences might be thought to give rise to, and one way to resolve them.
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.
Teleological Theories of Mental Content
Abstract: Teleological theories of mental content try to explain the contents of mental representations by appealing to a teleological notion of function. Take, for example, the thought that blossoms are forming. On a representational theory of thought, this thought involves a representation of blossoms forming. A theory of content aims among other things to tell us why this representation has that content; it aims to say why it is a thought about blossoms forming rather than about the sun shining or pigs flying or nothing at all. In general, a theory of content tries to say why a mental representation counts as representing what it represents.
According to teleological theories of content, what a representation represents depends on the functions of the systems that produce or use the representation. The relevant notion of function is said to be the one that is used in biology and neurobiology in attributing functions to components of organisms (as in “the function of the pineal gland is secreting melatonin” and “the function of brain area MT is processing information about motion”). Proponents of teleological theories of content generally understand such functions to be what the thing with the function was selected for, either by ordinary natural selection or by some other natural process of selection.
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.
Causation: A Very Short Introduction
Publisher’s Note: Causation is the most fundamental connection in the universe. Without it, there would be no science or technology. There would be no moral responsibility either, as none of our thoughts would be connected with our actions and none of our actions with any consequences. Nor would we have a system of law because blame resides only in someone having caused injury or damage.
Any intervention we make in the world around us is premised on there being causal connections that are, to a degree, predictable. It is causation that is at the basis of prediction and also explanation. This Very Short Introduction introduces the key theories of causation and also the surrounding debates and controversies. Do causes produce their effects by guaranteeing them? Do causes have to precede their effects? Can causation be reduced to the forces of physics? And are we right to think of causation as one single thing at all?
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.
Causality and Determination
Summary: A classic text in which Anscombe argues for a realist view of causation. Specifically, Anscombe holds that causation is both directly perceivable and not subject to philosophical analysis. Anscombe seeks to establish that causal relations do not presuppose laws, and that causal relations can be perceived in a direct way.
