"The first two lectures place the alternative I defend -- a kind of pragmatic realism -- in a historical and metaphysical context. Part of that context is provided by Husserl's remark that the history of modern philosophy begins with Galileo -- that is, modern philosophy has been hypnotized by the idea that scientific facts are all the facts there are. Another part is provided by the analysis of a very simple example of what I call 'contextual relativity'. The position I (...) defend holds that truth depends on conceptual scheme and it is nonetheless 'real truth'. "In my third lecture I turn to the Kantian antecedents of this view, explaining what I think should be retained of the Kantian idea of autonomy as the central theme of morality, and extracting from Kant's work a 'moral image of the world' that connects the ideals of equality and intellectual liberty. In this lecture I defend the idea that moral images are an indispensible part of our moral and cultural heritage. "In the final lecture I defend the idea of moral objectivity. I compare our epistemological positions in ethics, history, analysis of human character, and science, and I argue that in no area can we hope for a 'foundation' which is more ultimate than the beliefs that actually, at a given time, function as foundational in the area, the beliefs concerning which one has to say 'this is where my spade is turned'. In ethics such beliefs are represented in moral images of the world.". (shrink)

As the eleventh volume in the New Directions in Cognitive Science series (formerly the Vancouver Studies in Cognitive Science series), this work promises superb scholarship and interdisciplinary appeal. It addresses three areas of current and varied interest: common sense, reasoning, and rationality. While common sense and rationality often have been viewed as two distinct features in a unified cognitive map, this volume offers novel, even paradoxical, views of the relationship. Comprised of outstanding essays from distinguished philosophers, it considers what constitutes (...) human rationality, behavior, and intelligence covering diverse areas of philosophy, psychology, cognitive science, and computer science. Indeed, it is at the forefront of cognitive research and promises to be of unprecedented influence across numerous disciplines. (shrink)

Knowledge in a Social World offers a philosophy for the information age. Alvin Goldman explores new frontiers by creating a thoroughgoing social epistemology, moving beyond the traditional focus on solitary knowers. Against the tides of postmodernism and social constructionism Goldman defends the integrity of truth and shows how to promote it by well-designed forms of social interaction. From science to education, from law to democracy, he shows why and how public institutions should seek knowledge-enhancing practices. The result is a bold, (...) timely, and systematic treatment of the philosophical foundations of an information society. (shrink)

Against the traditional view, Alvin Goldman argues that logic, probability theory, and linguistic analysis cannot by themselves delineate principles of rationality or justified belief. The mind's operations must be taken into account.

This systematic investigation of computation and mental phenomena by a noted psychologist and computer scientist argues that cognition is a form of computation, that the semantic contents of mental states are encoded in the same general way as computer representations are encoded.

Artificial intelligence research has foundered on the issue of representation. When intelligence is approached in an incremental manner, with strict reliance on interfacing to the real world through perception and action, reliance on representation disappears. In this paper we outline our approach to incrementally building complete intelligent Creatures. The fundamental decomposition of the intelligent system is not into independent information processing units which must interface with each other via representations. Instead, the intelligent system is decomposed into independent and parallel activity (...) producers which all interface directly to the world through perception and action, rather than interface to each other particularly much. The notions of central and peripheral systems evaporateeverything is both central and peripheral. Based on these principles we have built a very successful series of mobile robots which operate without supervision as Creatures in standard office environments. (shrink)

One of the most important Anglo-American philosophers of our time here joins the current philosophical debate about the nature of truth. William P. Alston formulates and defends a realist conception of truth, which he calls alethic realism. This idea holds that the truth value of a statement depends on whether what the statement is about is as the statement says it is. Michael Dummett and Hilary Putnam are two of the prominent and widely influential contemporary philosophers whose anti-realist ideas Alston (...) attacks. (shrink)

John Searle began to discuss his recently published book `The Construction of Social Reality' with Anthony Freeman, and they ended up talking about God. The book itself and part of their conversation are introduced and briefly reflected upon by Anthony Freeman. Many familiar social facts -- like money and marriage and monarchy -- are only facts by human agreement. They exist only because we believe them to exist. That is the thesis, at once startling yet obvious, that philosopher John Searle (...) explores in The Construction of Social Reality. (shrink)

Bertrand Russell was one of the greatest logicians since Aristotle, and one of the most important philosophers of the past two hundred years. As we approach the 125th anniversary of the Nobel laureate's birth, his works continue to spark debate, resounding with unmatched timeliness and power. The Problems of Philosophy, one of the most popular works in Russell's prolific collection of writings, has become core reading in philosophy. Clear and accessible, this little book is an intelligible and stimulating guide to (...) those problems of philosophy which often mistakenly lead to its status as too lofty and abstruse for the lay mind. Focusing on problems he believes will provoke positive and constructive discussion, Russell concentrates on knowledge rather than metaphysics, steering the reader through his famous 1910 distinction between "knowledge by acquaintance and knowledge by description," and introducing important theories of Descartes, Kant, Hegel, Hume, Locke, Plato, and others to lay the foundation for philosophical inquiry by general readers and scholars alike.With a new introduction by John Perry, this valuable work is a perfect introduction to the field and will continue to stimulate philosophical discussion as it has done for nearly forty years.

This thesis offers a theory of actual human cognizers' epistemic connection to truth of their beliefs or statements. It comprises four major parts. First, I develop a quasirealist metaphysic which differs, in fundamental ways, from the customary realist and anti-realist ontologies. Second, I produce an account of nonepistemic truth and truthmaking relation according to which there is an irreducible logical gap between the concepts of propositional truth and evidential support. Although such a characterization places me in the same camp with (...) the realists regarding the independence of the notion of propositional truth from that of evidence, I endorse antirealism with respect to the medium or "world" in/through which truths are made. Third, I question the ubiquitous supposition that nonepistemic truth is a necessary condition of propositional knowledge, concluding that it is not as sound as it first seems. Finally, I employ the ideas that have been developed in the preceding chapters in order to answer the question of the possibility and nature of higher-level empirical knowledge. The resultant account is a linguistic Kantian theory of actual---as opposed to misleadingly idealized---human agents' alethic world, and, in this sense, it shares the gist of Immanuel Kant's epistemic-ontological perspective: we do have reliable and objective knowledge of the world around us; but this certainly does not mean that such knowledge comes without substantial limits.

Focusing on Truth explores the question of what truth is, balancing historical with issue-orientated discussion. The book offers a comprehensive survey of all the major theories of truth. Lawrence Johnson investigates a number of closely related matters of truth in his inquiry, such as: What sorts of things are true or false? What is attributed to them when they are said to be true or false? What do facts have to do with truth? What can we learn from previous theories? (...) The book opens with an analysis of the coherence theory of truth and then the correspondence theory of truth, as developed by Moore, Russell and Wittgenstein. Through a study of the semantic conceptions of truth, the author reveals that an adequate theory of truth must take account of the pragmatics of person, purpose, and circumstance. A full understanding of facts and truth bearers is considered central to Johnson's criticism of the opposing truth theories of J. L. Austin and P. F. Strawson. Drawing on the merits of these theories and others, while identifying their deficiencies, Johnson presents a new account of truth, based on the correlation of referential foci and the use of linguistic conventions. This account is defended as being adequate to meet the legitimate demands made on a theory of truth. Johnson argues that the account leaves scope for statements of many different sorts to be true in their own widely varying ways, without the existence of a need to posit fundamentally different kinds of truth.

Are humans rational? Various experiments performed over the last several decades have been interpreted as showing that humans are irrational we make significant and consistent errors in logical reasoning, probabilistic reasoning, similarity judgements, and risk-assessment, to name a few areas. But can these experiments establish human irrationality, or is it a conceptual truth that humans must be rational, as various philosophers have argued? In this book, Edward Stein offers a clear critical account of this debate about rationality in philosophy and (...) cognitive science. He discusses concepts of rationality - the pictures of rationality that the debate centres on - and assesses the empirical evidence used to argue that humans are irrational. He concludes that the question of human rationality must be answered not conceptually but empirically, using the full resources of an advanced cognitive science. Furthermore, he extends this conclusion to argue that empirical considerations are also relevant to the theory of knowedge - in other words, that epistemology should be naturalized. from the reviews: 'Stein has done a great service in bringing together all of the important arguments in the human rationality debate and providing a measured critical assessment of them....

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)

This book offers an introductory account of the central theories of truth. A wide range of theories, from those of correspondence and coherence to Tarski's semantic conception of truth are presented and assessed in order to profit from that which is of value in them. The authot proposes a new account which it is asserted is adequate to meet the legitimate demands made on the theory of truth.

Can the output of human cognition be predicted from the assumption that it is an optimal response to the information-processing demands of the environment? A methodology called rational analysis is described for deriving predictions about cognitive phenomena using optimization assumptions. The predictions flow from the statistical structure of the environment and not the assumed structure of the mind. Bayesian inference is used, assuming that people start with a weak prior model of the world which they integrate with experience to develop (...) stronger models of specific aspects of the world. Cognitive performance maximizes the difference between the expected gain and cost of mental effort. Memory performance can be predicted on the assumption that retrieval seeks a maximal trade-off between the probability of finding the relevant memories and the effort required to do so; in categorization performance there is a similar trade-off between accuracy in predicting object features and the cost of hypothesis formation; in casual inference the trade-off is between accuracy in predicting future events and the cost of hypothesis formation; and in problem solving it is between the probability of achieving goals and the cost of both external and mental problem-solving search. The implemention of these rational prescriptions in neurally plausible architecture is also discussed. (shrink)

A Choice Outstanding Academic Title for 1999 Academic debates about pluralism and truth have become increasingly polarized in recent years. One side embraces extreme relativism, deeming any talk of objective truth as philosophically naïve. The opposition, frequently arguing that any sort of relativism leads to nihilism, insists on an objective notion of truth according to which there is only one true story of the world. Both sides agree that there is no middle path. In Truth in Context, Michael Lynch argues (...) that there is a middle path, one where metaphysical pluralism is consistent with a robust realism about truth. Drawing on the work of Hilary Putnam, W.V.O. Quine, and Ludwig Wittgenstein, among others, Lynch develops an original version of metaphysical pluralism, which he calls relativistic Kantianism. He argues that one can take facts and propositions as relative without implying that our ordinary concept of truth is a relative, epistemic, or "soft" concept. The truths may be relative, but our concept of truth need not be. (shrink)

This paper aims to describe and defend a Pluralistic Kantian, as opposed to a Tractarian, version of realism vis-à-vis the ontological basis of truthmaking relations. One underlying assumption of my position is that propositional truth is a robust property and, consequently, is normatively distinct from epistemic justification. Still, it does not follow from this realist contention that truth is generated ontologically, viz., independently of cognitive and intensional contributions of human agents. This point brings my view notably close to H. Putnam’s (...) peculiar blend of certain Wittgensteinian and Kantian themes. However, I argue that Putnam’s apparent denial of the in-itself reality with an intrinsic structure gives rise to a rather un-Kantian and problematic metaphysical picture. I suggest that the solution to the puzzle may be found in a synthesis of the best intuitions of Armstrong’s Tractarian realism and Putnam’s quasi-Kantianism. (shrink)
