Summary: Cartwright explains and defends the view that causal capacities are more fundamental than laws of nature. She does this by considering scientific practice: the kind of knowledge required to make experimental setups and predictions is knowledge of the causal capacities of the entities in those systems, not knowledge of laws of nature.
Mathematics and Reality
Publisher’s Note: Mary Leng offers a defense of mathematical fictionalism, according to which we have no reason to believe that there are any mathematical objects. Perhaps the most pressing challenge to mathematical fictionalism is the indispensability argument for the truth of our mathematical theories (and therefore for the existence of the mathematical objects posited by those theories). According to this argument, if we have reason to believe anything, we have reason to believe that the claims of our best empirical theories are (at least approximately) true. But since claims whose truth would require the existence of mathematical objects are indispensable in formulating our best empirical theories, it follows that we have good reason to believe in the mathematical objects posited by those mathematical theories used in empirical science, and therefore to believe that the mathematical theories utilized in empirical science are true. Previous responses to the indispensability argument have focussed on arguing that mathematical assumptions can be dispensed with in formulating our empirical theories. Leng, by contrast, offers an account of the role of mathematics in empirical science according to which the successful use of mathematics in formulating our empirical theories need not rely on the truth of the mathematics utilized.
Truth deserves to be believed
Abstract: Science seems generally to aim at truth. And governmental support of science is often premised on the instrumental value of truth in service of advancing our practical objectives, both as individuals and as communities, large and small. While there is some political expediency to this view, it is not correct. The value of truth is nowise that it helps us achieve our aims. In fact, just the contrary: truth deserves to be believed only on the condition that its claim upon us is orthogonal to any utility it might have in the service of (any and all) practical ends
Representationalism
Abstract: Representationalism, in its most widely accepted form, is the view that the human mind is an information-using system, and that human cognitive capacities are to be understood as representational capacities. This chapter distinguishes several distinct theses that go by the name “representationalism,” focusing on the view that is most prevalent in cogntive science. It also discusses some objections to the view and attempts to clarify the role that representational content plays in cognitive models that make use of the notion of representation.
Truth and Meaning: An Introduction to the Philosophy of Language
Summary: This lucid and wide-ranging volume constitutes a self-contained introduction to the elements and key issues of the philosophy of language. In particular, it focuses on the philosophical foundations of semantics, including the main challenges to and prospects for a truth conditional semantics. Since the book is neither single-mindedly philosophical, nor single-mindedly technical, it is an accessible introduction to the philosophical foundations of semantics, and will provide the ideal basis for a first course in the philosophy of language and philosophical logic.
Perception and Action: Alternative Views
Abstract: A traditional view of perception and action makes two assumptions: that the causal flow between perception and action is primarily linear or one-way, and that they are merely instrumentally related to each other, so that each is a means to the other. Either or both of these assumptions can be rejected. Behaviorism rejects the instrumental but not the one-way aspect of the traditional view, thus leaving itself open to charges of verificationism. Ecological views reject the one-way aspect but not the instrumental aspect of the traditional view, so that perception and action are seen as instrumentally interdependent. It is argued here that a better alternative is to reject both assumptions, resulting in a two-level interdependence view in which perception and action co-depend on dynamically circular subpersonal relations and as a result may be more than merely instrumentally interdependent. This is illustrated by reference to motor theories of perception and control theories of action.
Persistence Through Time
Introduction: Things change: objects come into existence, last for a while, go out of existence, move through space, change their parts, change their qualities, change in their relations to things. All this would seem to be uncontroversial. But philosophical attention to any of these phenomena can generate perplexity and has resulted in a number of long-standing puzzles. One of the most famous puzzles about change threatens to demonstrate that nothing can persist through time, that all existence is momentary at best. Let’s use the term ‘alteration’ for the sort of change that occurs when a persisting object changes its properties.
Against Creationism in Fiction
Abstract: Sherlock Holmes is a fictional individual. So is his favorite pipe. Our pre-theoretical intuition says that neither of them is real. It says that neither of them really, or actually, exists. It also says that there is a sense in which they do exist, namely, a sense in which they exist “in the world of” the Sherlock Holmes stories. Our pre-theoretical intuition says in general of any fictional individual that it does not actually exist but exists “in the world of” the relevant fiction. I wish to defend this pre-theoretical intuition. To do so, I need to defend two claims: that fictional individuals do not actually exist, and that they exist “in the world of” the relevant fiction. The aim of this paper is to defend the first claim.
Possible Objects
Abstract: Deep theorizing about possibility requires theorizing about possible objects. One popular approach regards the notion of a possible object as intertwined with the notion of a possible world. There are two widely discussed types of theory concerning the nature of possible worlds: actualist representationism and possibilist realism. They support two opposing views about possible objects. Examination of the ways in which they do so reveals difficulties on both sides. There is another popular approach, which has been influenced by the philosophy of Alexius Meinong. The Meinongian approach is relevant to theorizing about possible objects because it attempts to construct a general theory of objects other than ordinary concrete existing objects. Independently of the debate about the nature of possible worlds or about Meinongianism, it is not always as straightforward as it may at first appear to determine whether putative possible objects are indeed possible. Another category of object similar to that of a possible object is the category of a fictional object. Although initially attractive, the idea that fictional objects are possible objects should not be accepted blindly. An important instance of theoretical usefulness of possible objects is their central role in the validation of two controversial theorems of a simple quantified modal logic.
We Are Living in a Material World (And I am a Material Girl)
Abstract: In this paper I examine the question of whether the characterization of physicalism that is presupposed by some influential anti-physicalist arguments, namely, the so-called conceivability arguments, is a good characterization of physicalism or not. I compare this characterization with some alternative ones, showing how it can overcome some problems, and I defend it from several objections. I conclude that any arguments against physicalism characterised in that way are genuine arguments against physicalism, as intuitively conceived.
