During the last 25 years, researchers studying human reasoning and judgment in what has become known as the “heuristics and biases” tradition have produced an impressive body of experimental work which many have seen as having “bleak implications” for the rationality of ordinary people (Nisbett and Borgida 1975). According to one proponent of this view, when we reason about probability we fall victim to “inevitable illusions” (Piattelli-Palmarini 1994). Other proponents maintain that the human mind is prone to “systematic deviations from rationality” (Bazerman & Neale 1986) and is “not built to work by the rules of probability” (Gould 1992). It has even been suggested that human beings are “a species that is uniformly probability-blind” (Piattelli-Palmarini 1994). This provocative and pessimistic interpretation of the experimental findings has been challenged from many different directions over the years. One of the most recent and energetic of these challenges has come from the newly emerging field of evolutionary psychology, where it has been argued that it’s singularly implausible to claim that our species would have evolved with no “instinct for probability” and, hence, be “blind to chance” (Pinker 1997, 351). Though evolutionary psychologists concede that it is possible to design experiments that “trick our probability..

Donald Davidson did it. He did it slowly, deliberately, in more than a half dozen widely noted essays. What he did was to elaborate a program for the study of empirical semantics. Nor did he stop there. He went on to apply his program to some of the problems that have long bedeviled semantics: action sentences, indirect discourse and propositional attitudes. My goal in this paper is to assess Davidson's achievement. The first step is to assemble the program from the sketches and hints scattered among Davidson's papers. This is the project of my first section where my aim is sympathetic exposition. Since Davidson sometimes seems to be playing a game of hide and seek with his reader, my reconstruction of his program and arguments is of necessity occasionally speculative. In the second section my stance turns critical. There are anomalies in the program; the sort of theory Davidson advocates is not the sort delivered. When the problems are pushed, I think the program loses whatever initial plausibility it may have had. It is my contention that Davidson has provided no serious framework for the empirical study of natural language.

It is argued that the relation between ‘occurrents’ as characterized by Honderich and familiar ‘contentful’ mental states like beliefs and thoughts is a very murky one. Occurrents are distinct when and only when they can be distinguished by consciousness. By contrast, the criteria of individuation for contentful mental states invoke factors that are not distinguishable by consciousness. It is also suggested that Honderich's strategy for individuating occurrents may sometimes be difficult to apply.

The flight to reference is a widely-used strategy for resolving philosophical issues. The three steps in a flight to reference argument are: (1) offer a substantive account of the reference relation, (2) argue that a particular expression refers (or does not refer), and (3) draw a philosophical conclusion about something other than reference, like truth or ontology. It is our contention that whenever the flight to reference strategy is invoked, there is a crucial step that is left undefended, and that without a defense of this step, the flight to reference is a fatally flawed strategy; it cannot succeed in resolving philosophical issues. In this paper we begin by setting out the flight to reference strategy and explaining what is wrong with arguments that invoke the strategy. We then illustrate the problem by considering arguments for and against eliminative materialism. In the final section we argue that much the same problem undermines Philip Kitcher's attempt to defend scientific realism.

The controversy over inference in perception turns on the nature of the processes that intervene between the stimulus and the perceptual experience or percept. Should the processes be viewed as something like inference and computation, or should they be viewed as psychologically primitive mechanisms whose workings are best accounted for at a neurological or physiological level? It is argued that the view that computational and inference-like processes play a role in perceptual processes should be adopted.

Humans are unique in the animal world in the extent to which their day-to-day behavior is governed by a complex set of rules and principles commonly called norms. Norms delimit the bounds of proper behavior in a host of domains, providing an invisible web of normative structure embracing virtually all aspects of social life. People also find many norms to be deeply meaningful. Norms give rise to powerful subjective feelings that, in the view of many, are an important part of what it is to be a human agent. Despite the vital role of norms in human lives and human behavior, and the central role they play in explanations in the social sciences, there has been very little systematic attention devoted to norms in cognitive science. Much existing research is partial and piecemeal, making it difficult to know how individual findings cohere into a comprehensive picture. Our goal in this essay is to offer an account of the psychological mechanisms and processes underlying norms that integrates what is known and can serve as a framework for future research.

  Along with the increasing popularity of connectionist language models has come a number of provocative suggestions about the challenge these models present to Chomsky's arguments for nativism. The aim of this paper is to assess these claims. We begin by reconstructing Chomsky's argument from the poverty of the stimulus and arguing that it is best understood as three related arguments, with increasingly strong conclusions. Next, we provide a brief introduction to connectionism and give a quick survey of recent efforts to develop networks that model various aspects of human linguistic behavior. Finally, we explore the implications of this research for Chomsky's arguments. Our claim is that the relation between connectionism and Chomsky's views on innate knowledge is more complicated than many have assumed, and that even if these models enjoy considerable success the threat they pose for linguistic nativism is small

For about 2500 years, from Plato’s time until the closing decades of the 20^th century, the dominant view was that the emotions are quite distinct from the processes of rational thinking and decision making, and are often a major impediment to those processes. But in recent years this orthodoxy has been challenged in a number of ways. Damasio (1994) has made a forceful case that the traditional view, which he has dubbed _Descartes’ Error_, is quite wrong, because emotions play a fundamental role in rational decision making. When the systems underlying the emotions don’t function properly, Damasio maintains, rational decision-making breaks down. Other theorists, most notably Robert Frank (1988), have argued that if we view the emotions through the longer lens of evolutionary theory, we can see that much of what looked to be irrational in the emotions is actually part of an effective strategy for achieving agents’ goals and maximizing their reproductive success. In the wake of this and other recent work, the pendulum of received opinion has swung in the other direction. The emotions are now increasingly regarded as inherently rational, as Frank maintains, and as important components of other rational processes

Intuitions play an important role in contemporary epistemology. Over the last decade, however, experimental philosophers have published a number of studies suggesting that epistemic intuitions may vary in ways that challenge the widespread reliance on intuitions in epistemology. In a recent paper, Jennifer Nagel offers a pair of arguments aimed at showing that epistemic intuitions do not, in fact, vary in problematic ways. One of these arguments relies on a number of claims defended by appeal to the psychological literature on intuitive judgment and on mental state attribution (also known as “theory of mind”, “mindreading” and “folk psychology”). I call this the "theoretical argument". The other argument relies on recent experimental work carried out by Nagel and her collaborators. It is my contention that in setting out her theoretical argument, Nagel offers an account of the relevant scientific literature that is, in crucial respects, flawed and misleading. My main goal in this paper is to rectify these errors and to make it clear that, once this is done, Nagel’s theoretical argument collapses. Since Nagel’s experimental work has not yet been published, and available details are very sketchy, I do not discuss this work in detail. However, in the final section of the paper I offer some critical observations about Nagel’s strategy for dealing with empirical data that does not support her view – both other people’s and her own.

In recent years there has been a great deal of discussion about the prospects of developing a ‘naturalized epistemology’, though different authors tend to interpret this label in quite different ways. One goal of this paper is to sketch three projects that might lay claim to the ‘naturalized epistemology’ label, and to argue that they are not all equally attractive. Indeed, I'll maintain that the first of the three—the one I'll attribute to Quine—is simply incoherent. There is no way we could get what we want from an epistemological theory by pursuing the project Quine proposes. The second project on my list is a naturalized version of reliabilism. This project is not fatally flawed in the way that Quine's is. However, it's my contention that the sort of theory this project would yield is much less interesting than might at first be thought.

The debate over recombinant DNA research is a unique event, perhaps a turning point, in the history of science. For the first time in modern history there has been widespread public discussion about whether and how a promising though potentially dangerous line of research shall be pursued. At root the debate is a moral debate and, like most such debates, requires proper assessment of the facts at crucial stages in the argument. A good deal of the controversy over recombinant DNA research arises because some of the facts simply are not yet known. There are many empirical questions we would like to have answered before coming to a decision-questions about the reliability of proposed containment facilities, about the viability of enfeebled strains of E. coli, about the ways in which pathogenic organisms do their unwelcome work, and much more. But all decisions cannot wait until the facts are available; some must be made now. It is to be expected that people with different hunches about what the facts will turn out to be will urge different decisions on how recombinant DNA research should be regulated. However, differing expectations about the facts have not been the only fuel for controversy. A significant part of the current debate can be traced to differences over moral principles. Also, unfortunately, there has been much unnecessary debate generated by careless moral reasoning and a failure to attend to the logical structure of some of the moral arguments that have been advanced.

1. When we attribute beliefs, desires, and other states of common sense psychology to a person, or for that matter to an animal or an artifact, we are assuming or presupposing that the person or object can be treated as an intentional system. 2. An intentional system is one which is rational through and through; its beliefs are those it ought to have, given its perceptual capacities, its epistemic needs, and its biography…. Its desires are those it ought to have, given its biological needs and the most practicable means of satisfying them…. And its behavior will consist of those acts that it would be rational for an agent with those beliefs and desires to perform. [beliefs + desires  action] 3. If rationality is absent, we cannot coherently ascribe beliefs at all. 4. Therefore, no experiment could demonstrate that people systematically invoke invalid or irrational inferential strategies.
