From Descartes to Popper, philosophers have criticized and tried to improve the strategies of reasoning invoked in science and in everyday life. In recent years leading cognitive psychologists have painted a detailed, controversial, and highly critical portrait of common sense reasoning. Stephen Stich begins with a spirited defense of this work and a critique of those writers who argue that widespread irrationality is a biological or conceptual impossibility.Stich then explores the nature of rationality and irrationality: What is it that distinguishes (...) good reasoning from bad? He rejects the most widely accepted approaches to this question approaches which unpack rationality by appeal to truth, to reflective equilibrium or conceptual analysis. The alternative he defends grows out of the pragmatic tradition in which reasoning is viewed as a cognitive tool. Stich's version of pragmatism leads to a radical epistemic relativism and he argues that the widespread abhorrence of relativism is ill founded. (shrink)

According to some philosophers, we are “cognitively closed” to the answers to certain problems. McGinn has taken the next step and offered a list of examples: the mind/body problem, the problem of the self and the problem of free will. There are naturalistic, scientific answers to these problems, he argues, but we cannot reach them because of our cognitive limitations. In this paper, we take issue with McGinn's thesis as the most well-developed and systematic one among the so-called “new mysterians”. (...) McGinn aims to establish a strong, representational notion of cognitive closure: a principled inaccessibility of a true theory of certain properties of the world, but he offers arguments that only bear on difficulties with psychologically grasping the correct answers. The latter we label psychological closure. We argue that representational closure does not follow from psychological closure, and that McGinn's case therefore falters. We could very well be able to represent the correct answer to some question, even without being able to grasp that answer psychologically. McGinn's mistake in deriving representational closure from psychological closure rests on a fallacy of equivocation relating to the concept of ‘understanding’. By making this distinction explicit, we hope to improve our thinking about the limits of science in particular and human knowledge in general. (shrink)

The now-classic Metaphors We Live By changed our understanding of metaphor and its role in language and the mind. Metaphor, the authors explain, is a fundamental mechanism of mind, one that allows us to use what we know about our physical and social experience to provide understanding of countless other subjects. Because such metaphors structure our most basic understandings of our experience, they are "metaphors we live by"--metaphors that can shape our perceptions and actions without our ever noticing them. In (...) this updated edition of Lakoff and Johnson's influential book, the authors supply an afterword surveying how their theory of metaphor has developed within the cognitive sciences to become central to the contemporary understanding of how we think and how we express our thoughts in language.

The paper discusses Colin McGinn’s mysterianist approach to the phenomenon of consciousness. According to McGinn, consciousness is, in and of itself, a fully natural phenomenon, but we humans are just cognitively closed to it, meaning that we cannot in principle understand its nature. I argue that, on a proper conception of the relation between an intellectual problem and its solution, we may well not know what the solution is to a problem we understand, or we may not understand exactly what (...) the problem is, but it is incoherent to suppose that we cannot understand what would count as a solution to a problem we can and do understand. The argument appeals to certain accepted assumption in the logic of questions, developed in the early sixties, mainly by Stahl. I close with a general characterization of mysterianism as such, and formulate a form of mysterianism which is in some sense more optimistic and in another more pessimistic than McGinn’s. (shrink)

As the subtitle indicates, this book is concerned with the relationship between consciousness and the physical world. It recommends a novel and disturbingly pessimistic view about this topic that it calls “naturalistic mysterianism.” The view is naturalistic because it maintains that states of consciousness are reducible to physical properties of the brain. It counts as “mysterian” because it asserts that the physical properties in question are entirely beyond our ken—that they lie well beyond the scope of contemporary neuroscience, and quite (...) likely beyond the scope of any body of scientific knowledge that we might develop in the future. Naturalistic mysterianism thus affirms the unity of consciousness with the physical world, while also claiming that the nature of that unity will forever elude us, due to inherent limits of our cognitive capacities.

Certain enterprises at the fringes of science, such as intelligent design creationism, claim to identify phenomena that go beyond not just our present physics but any possible physical explanation. Asking what it would take for such a claim to succeed, we introduce a version of physicalism that formulates the proposition that all available data sets are best explained by combinations of “chance and necessity”—algorithmic rules and randomness. Physicalism would then be violated by the existence of oracles that produce certain kinds (...) of noncomputable functions. Examining how a candidate for such an oracle would be evaluated leads to questions that do not admit an easy resolution. Since we lack any plausible candidate for any such oracle, however, chance-and-necessity physicalism appears very likely to be correct. (shrink)

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

The scientific study of living organisms is permeated by machine and design metaphors. Genes are thought of as the ‘‘blueprint’’ of an organism, organisms are ‘‘reverse engineered’’ to discover their func- tionality, and living cells are compared to biochemical factories, complete with assembly lines, transport systems, messenger circuits, etc. Although the notion of design is indispensable to think about adapta- tions, and engineering analogies have considerable heuristic value (e.g., optimality assumptions), we argue they are limited in several important respects. In (...) particular, the analogy with human-made machines falters when we move down to the level of molecular biology and genetics. Living organisms are far more messy and less transparent than human-made machines. Notoriously, evolution is an oppor- tunistic tinkerer, blindly stumbling on ‘‘designs’’ that no sensible engineer would come up with. Despite impressive technological innovation, the prospect of artificially designing new life forms from scratch has proven more difficult than the superficial analogy with ‘‘programming’’ the right ‘‘software’’ would sug- gest. The idea of applying straightforward engineering approaches to living systems and their genomes— isolating functional components, designing new parts from scratch, recombining and assembling them into novel life forms—pushes the analogy with human artifacts beyond its limits. In the absence of a one-to-one correspondence between genotype and phenotype, there is no straightforward way to imple- ment novel biological functions and design new life forms. Both the developmental complexity of gene expression and the multifarious interactions of genes and environments are serious obstacles for ‘‘engi- neering’’ a particular phenotype. The problem of reverse-engineering a desired phenotype to its genetic ‘‘instructions’’ is probably intractable for any but the most simple phenotypes. Recent developments in the field of bio-engineering and synthetic biology reflect these limitations. Instead of genetically engi- neering a desired trait from scratch, as the machine/engineering metaphor promises, researchers are making greater strides by co-opting natural selection to ‘‘search’’ for a suitable genotype, or by borrowing and recombining genetic material from extant life forms.

True beliefs are better guides to the world than false ones. This is the common-sense assumption that undergirds theorizing in evolutionary epistemology. According to Alvin Plantinga, however, evolution by natural selection does not care about truth: it cares only about fitness. If our cognitive faculties are the products of blind evolution, we have no reason to trust them, anytime or anywhere. Evolutionary naturalism, consequently, is a self-defeating position. Following up on earlier objections, we uncover three additional flaws in Plantinga's latest (...) formulation of his argument: a failure to appreciate adaptive path dependency, an incoherent conception of content ascription, and a conflation of common-sense and scientific beliefs, which we diagnose as the ‘foundationalist fallacy’. More fundamentally, Plantinga's reductive formalism with respect to the issue of cognitive reliability is inadequate to deal with relevant empirical details. (shrink)

Reexamines the Western philosophical tradition, looking at the basic concepts of the mind, time, causation, morality, and the self.

This book is an outstanding contribution to the philosophical study of language and mind, by one of the most influential thinkers of our time. In a series of penetrating essays, Chomsky cuts through the confusion and prejudice which has infected the study of language and mind, bringing new solutions to traditional philosophical puzzles and fresh perspectives on issues of general interest, ranging from the mind-body problem to the unification of science. Using a range of imaginative and deceptively simple linguistic analyses, (...) Chomsky defends the view that knowledge of language is internal to the human mind. He argues that a proper study of language must deal with this mental construct. According to Chomsky, therefore, human language is a 'biological object' and should be analyzed using the methodology of the sciences. His examples and analyses come together in this book to give a unique and compelling perspective on language and the mind. (shrink)

How does science work? _Making Truth: Metaphor in Science_ argues that most laypeople, and many scientists, do not have a clear understanding of how metaphor relates to scientific thinking. With stunning clarity, and bridging the worlds of scientists and nonscientists, Theodore L. Brown demonstrates the presence and the power of metaphorical thought. He presents a series of studies of scientific systems, ranging from the atom to current topics in chemistry and biology such as protein folding, chaperone proteins, and global warming. (...) These case studies provide the basis for far-reaching conclusions about science as an intellectual and social practice and about the nature of scientific truth. (shrink)

The book formulates an evolutionary approach to the theory of knowledge, based on the parallelism between the natural selection of our cognitive capacities and the rational selection of the methodological processes by which we put them to work. The former reflects the biological evolution of homo sapiens, the latter the cultural evolution of homo quaerens through the development of a scientific community of inquirers with its characteristic practices. This dual aspect of cognitive evolution indicates that our human cognitive accomplishments are (...) limited by our particular evolutionary attunement to the world's scheme of things and are bound to reflect the character of our particular evolutionary niche. The resulting doctrinal position is one of a realistic relativism. (shrink)

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. (...) And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility. (shrink)

This study synthesizes current information from the various fields of cognitive science in support of a new and exciting theory of mind. Most psychologists study horizontal processes like memory and information flow; Fodor postulates a vertical and modular psychological organization underlying biologically coherent behaviors. This view of mental architecture is consistent with the historical tradition of faculty psychology while integrating a computational approach to mental processes. One of the most notable aspects of Fodor's work is that it articulates features not (...) only of speculative cognitive architectures but also of current research in artificial intelligence.

Language and Problems of Knowledge is sixteenth in the series Current Studies in Linguistics, edited by Jay Keyser.

When this book was originally published in 2006, Epistemetrics was not as yet a scholarly discipline. With regard to scientific information there was the discipline of scientometrics, represented by a journal of that very name. Science, however, had a monopoly on knowledge. Although it is one of our most important cognitive resources, it is not our only one. While scientometrics is a centerpiece of epistemetrics, it is not the whole of it. Nicholas Rescher's endeavor to quantify knowledge is not only (...) of interest in itself, but is also instructive in bringing into sharper relief the nature of and the explanatory rationale for the limits that unavoidably confront our efforts to advance the frontiers of knowledge. In particular, his book demonstrates the limitations of human knowledge and will be of great value to scholars working in this area. (shrink)

One of our most original thinkers addresses the scientific world's premier question: What is the nature of consciousness?

Aristotle's observation that all human beings by nature desire to know aptly captures the spirit of "intellectualist" research in psychology and anthropology. Intellectualists in these fields agree that humans' have fundamental explanatory interests (which reflect their rationality) and that the idioms in which their explanations are couched can differ considerably across places and times (both historical and developmental). Intellectualists in developmental psychology (e.g., Gopnik and Meltzoff, 1997) maintain that young children's conceptual structures, like those of scientists, are theories and that (...) their conceptual development--like the development of science--is a process of theory formation and change. They speculate that our explanatory preoccupations result, at least in part, from a natural drive to develop theories. Intellectualists in the anthropology of religion (e.g., Horton, 1970 and 1993) hold that, although it may do many other things as well, religion is primarily concerned with providing explanatory theories. They maintain that religion and science have the same explanatory goals; only the idioms of their explanations differ. The connections between the concern for explanation, the pursuit of science, the persistence of religion, and the cognitive processes underlying each clearly merit further examination. By considering both their cultural manifestations and their cognitive foundations, I hope to clarify not only how science and religion are related but some of the ways their explanatory projects differ. I shall argue that, despite their centuries' old antagonisms, no development in science will ever seriously threaten the persistence of religion or the forms of explanation religion employs or the emergence of new religions. (I strongly suspect that science will never seriously threaten the persistence of particular religions either, but I only aim to defend the weaker, collective claim here.) In this paper's fourth section I shall show that religion and its characteristic forms of explanation 1 are a natural outgrowth of the character and content of human association and cognition..

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? In this chapter we apply this argument to beliefs in three different domains: morality, religion, and science. We identify replies to evolutionary scepticism that work in some domains but not in others. The simplest reply to evolutionary scepticism is that the truth of beliefs (...) in a certain domain is, in fact, connected to evolutionary success, so that evolution can be expected to design systems that produce true beliefs in that domain. We call a connection between truth and evolutionary success a ‘Milvian bridge’, after the tradition which ascribes the triumph of Christianity at the battle of the Milvian bridge to the truth of Christianity. We argue that a Milvian bridge can be constructed for commonsense beliefs, and extended to scientific beliefs, but not to moral and religious beliefs. An alternative reply to evolutionary scepticism, which has been used defend moral beliefs, is to argue that their truth does not depend on their tracking some external state of affairs. We ask if this reply could be used to defend religious beliefs. (shrink)
