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.

Eliminativism has been a major focus of discussion in the philosophy of mind for the last two decades. According to eliminativists, beliefs and other intentional states are the posits of a folk theory of mind standardly called "folk psychology". That theory, they claim, is radically false and hence beliefs and other intentional states do not exist. We argue that the expression "folk psychology" is ambiguous in an important way. On the one hand, "folk psychology" is used by many philosophers and cognitive scientists to refer to an internally represented theory of human psychology exploited in the prediction of behavior. On the other hand, "folk psychology" is used to refer to the theory of mind implicit in our everyday talk about mental states. We then argue that sorting out the conceptual and terminological confusion surrounding "folk psychology" has major consequences for the eliminativism debate. In particular, if certain models of cognition turn out to be true, then on some readings of "folk psychology" the arguments for eliminativism collapse.

The aim of this paper is to demonstrate a prima facie tension between our commonsense conception of ourselves as thinkers and the connectionist programme for modelling cognitive processes. The language of thought hypothesis plays a pivotal role. The connectionist paradigm is opposed to the language of thought; and there is an argument for the language of thought that draws on features of the commonsense scheme of thoughts, concepts, and inference. Most of the paper (Sections 3-7) is taken up with the argument for the language of thought hypothesis. The argument for an opposition between connectionism and the language of thought comes towards the end (Section 8), along with some discussion of the potential eliminativist consequences (Sections 9 and..

The Cognitive Basis of Science concerns the question 'What makes science possible?' Specifically, what features of the human mind and of human culture and cognitive development permit and facilitate the conduct of science? The essays in this volume address these questions, which are inherently interdisciplinary, requiring co-operation between philosophers, psychologists, and others in the social and cognitive sciences. They concern the cognitive, social, and motivational underpinnings of scientific reasoning in children and lay persons as well as in professional scientists. The editors' introduction lays out the background to the debates, and the volume includes a consolidated bibliography that will be a valuable reference resource for all those interested in this area. The volume will be of great importance to all researchers and students interested in the philosophy or psychology of scientific reasoning, as well as those, more generally, who are interested in the nature of the human mind.

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.

Normative questions – particularly questions about what we should believe and how we should behave – have always been high on the agenda for philosophers, and over the centuries there has been no shortage of answers proposed. But this abundance of answers raises yet another fundamental philosophical question: How should we evaluate the proposed answers; how can we determine whether an answer to a normative question is a good one? The best known and most widely used method for evaluating answers to normative questions can be traced all the way back to Plato. Recently, however, cognitive scientists interested in cross cultural differences have reported findings that pose a serious challenge to this venerable philosophical method. Indeed, in light of these new findings some philosophers – I am one of them – have come to think that after 2400 years it may be time for philosophy to stop relying on Plato’s method. In the pages that follow I’ll sketch the path that led me to this conclusion.

For the last decade and more Noam Chomsky has been elaborating a skein of doctrines about language learning, linguistic universals, Empiricism and innate cognitive mechanisms. My aim in this paper is to pull apart some of the claims that Chomsky often defends collectively. In particular, I want to dissect out some contentions about the existence of linguistic universals. I shall argue that these claims, while they may be true, are logically independent from a cluster of claims Chomsky makes about Empiricism, language learning and innate cognitive mechanisms. The latter claims are, on my view, significantly more plausible than the former. Failure to note the logical space between the two has had lamentable consequences both for Chomsky and for his critics. Chomsky has been rather too ready to accept the existence of linguistic universals, and in arguing that one or another specific feature of a grammar is universal, he has consistently invoked an argument form of dubious merit. The critics, for their part, have sometimes argued against Chomsky's attack on Empiricist learning theories by criticizing Chomsky's views on language universals. If, as I shall maintain, the two positions are quite independent, then the critics' skepticism about linguistic universals is largely irrelevant to the Chomskian critique of Empiricist theories of learning.

Questions regarding the nature of moral judgment loom large in moral philosophy. Perhaps the most basic of these questions asks how, exactly, moral judgments and moral rules are to be defined; what features distinguish them from other sorts of rules and judgments? A related question concerns the extent to which emotion and reason guide moral judgment. Are moral judgments made mainly on the basis of reason, or are they primarily the products of emotion? As an example of the former view, Kant held all moral requirements to be derived from a principle of rationality (the categorical imperative). As an example of the latter, Hume famously claimed that reason is “the slave of the passions” and that moral judgments stem from the moral emotions. When addressing these issues, philosophers have largely relied on the traditional tools of philosophical analysis, along with introspection, anecdotal evidence and armchair speculation. In recent years, however, a rich body experimental psychology has emerged which, in the view of a growing number of philosophers, casts important new light on these venerable questions. Our aim, in this chapter, is to illustrate how empirical methods can help move traditional philosophical debates forward in interesting and important ways. Since space does not permit an exhaustive survey of the relevant experimental work, we will focus on a few of the most compelling examples.

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.
