Contains an overall account of morality in its philosophical format particularly with regard to problems of observation, evidence, and truth.

CRS says that the meanings of expressions of a language or other symbol system or the contents of mental states are determined and explained by the way symbols are used in thinking. According to CRS one.

Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory (...) coherence. Originally published in 1973. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Change in View offers an entirely original approach to the philosophical study of reasoning by identifying principles of reasoning with principles for revising one's beliefs and intentions and not with principles of logic. This crucial observation leads to a number of important and interesting consequences that impinge on psychology and artificial intelligence as well as on various branches of philosophy, from epistemology to ethics and action theory. Gilbert Harman is Professor of Philosophy at Princeton University. A Bradford Book.

BonJour offers two main reasons for supposing that there is such a thing as rational insight into necessity. First, he says there are many examples in which it clearly seems that one has such insight. Second, he argues that any epistemology denying the existence of rational insight into necessity is committed to a narrow skepticism. After commenting about possible frameworks for epistemological justification, I argue against these two claims in reverse order.

An attempt to analyse what it is for belief to be based on reasons becomes involved with questions about the goodness of reasons and the gettier examples. intuitions about knowledge and the "gettier effect" can be used to decide when reasoning has occurred and what reasoning there has been. explanation by reasons is not deterministic.

In this important new collection, Gilbert Harman presents a selection of fifteen interconnected essays on fundamental issues at the center of analytic philosophy. The book opens with a group of four essays discussing basic principles of reasoning and rationality. The next three essays argue against the once popular idea that certain claims are true and knowable by virtue of meaning. In the third group of essays Harman presents his own view of meaning and the possibility of thinking (...) in language The final three essays investigate the nature of mind, developing further the themes already set out. Reasoning, Meaning, and Mind offers an integrated presentation of this rich and influential body of work. which Harman has developed over thirty years. (shrink)

Williamson’s Knowledge and its Limits is the most important philosophical discussion of knowledge in many years. It sets the agenda for epistemology for the next decade and beyond.

In _Reliable Reasoning_, Gilbert Harman and Sanjeev Kulkarni -- a philosopher and an engineer -- argue that philosophy and cognitive science can benefit from statistical learning theory, the theory that lies behind recent advances in machine learning. The philosophical problem of induction, for example, is in part about the reliability of inductive reasoning, where the reliability of a method is measured by its statistically expected percentage of errors -- a central topic in SLT. After discussing philosophical attempts to (...) evade the problem of induction, Harman and Kulkarni provide an admirably clear account of the basic framework of SLT and its implications for inductive reasoning. They explain the Vapnik-Chervonenkis dimension of a set of hypotheses and distinguish two kinds of inductive reasoning. The authors discuss various topics in machine learning, including nearest-neighbor methods, neural networks, and support vector machines. Finally, they describe transductive reasoning and suggest possible new models of human reasoning suggested by developments in SLT. (shrink)

Explaining Value is a selection of the best of Gilbert Harman's shorter writings in moral philosophy. The thirteen essays are divided into four sections, which focus in turn on moral relativism, values and valuing, character traits and virtue ethics, and ways of explaining aspects of morality. Harman's distinctive approach to moral philosophy has provoked much interest; this volume offers a fascinating conspectus of his most important work in the area.

There has been considerable controversy about whether this last entailment always holds. Ordinary subjects may judge that (4) and (5) are appropriate in cases in which none of (1)-(3) are—cases in which Jack’s breaking the base is a foreseen but undesired consequence of Jack’s intentionally doing something else. It is currently debated what the best explanation of such ordinary reactions might be. It is also debated what to make of the fact that ordinary judgments using the adjective intentional or the (...) adverb intentionally seem influenced by normative considerations. (shrink)

Ordinary moral thought often commits what social psychologists call 'the fundamental attribution error '. This is the error of ignoring situational factors and overconfidently assuming that distinctive behaviour or patterns of behaviour are due to an agent's distinctive character traits. In fact, there is no evidence that people have character traits in the relevant sense. Since attribution of character traits leads to much evil, we should try to educate ourselves and others to stop doing it.

Do moral questions have objective answers? In this great debate, Gilbert Harman explains and argues for relativism, emotivism, and moral scepticism. In his view, moral disagreements are like disagreements about what to pay for a house; there are no correct answers ahead of time, except in relation to one or another moral framework. Independently, Judith Jarvis Thomson examines what she takes to be the case against moral objectivity, and rejects it; she argues that it is possible to find (...) out the correct answers to some moral questions. In her view, some moral disagreements are like disagreements about whether the house has a ghost. Harman and Thomson then reply to each other. This important, lively accessible exchange will be invaluable to all students of moral theory and meta-ethics. (shrink)

What is the real issue at stake in discussions of "moral explanation"? There isn't one; there are many. The standing of purported moral properties and problems about our epistemic or semantic access to them are of concern both from within and without moral practice. An account of their potential contribution to explaining our values, beliefs, conduct, practices, etc. can help in these respects. By examining some claims made about moral explanation in Judith Thompson's and Gilbert Harman's Moral Relativism (...) and Moral Objectivity, I try to suggest a worthwhile account of this potential explanatory contribution.

My thesis is that morality arises when a group of people reach an implicit agreement or come to a tacit understanding about their relations with one another. Part of what I mean by this is that moral judgments - or, rather, an important class of them - make sense only in relation to and with reference to one or another such agreement or understanding. This is vague, and I shall try to make it more precise in what follows. But it (...) should be clear that I intend to argue for a version of what has been called moral relativism. (shrink)
