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.

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.

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.

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

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)

Prince of Networks is the first treatment of Bruno Latour specifically as a philosopher. It has been eagerly awaited by readers of both Latour and Harman since their public discussion at the London School of Economics in February 2008. Part One covers four key works that display Latour’s underrated contributions to metaphysics: Irreductions, Science in Action, We Have Never Been Modern, and Pandora’s Hope. Harman contends that Latour is one of the central figures of contemporary philosophy, with a highly original (...) ontology centered in four key concepts: actants, irreduction, translation, and alliance. In Part Two, Harman summarizes Latour’s most important philosophical insights, including his status as the first ‘secular occasionalist.’ The problem of translation between entities is no longer solved by the fiat of God (Malebranche) or habit (Hume), but by local mediators. Working from his own ‘object-oriented’ perspective, Harman also criticizes the Latourian focus on the relational character of actors at the expense of their cryptic autonomous reality. This book forms a remarkable interface between Latour’s Actor-Network Theory and the Speculative Realism of Harman and his confederates. It will be of interest to anyone concerned with the emergence of new trends in the humanities following the long postmodernist interval. (shrink)

In this book the metaphysical system of Graham Harman is presented in lucid form, aided by helpful diagrams. In Chapter 1, Harman gives his most forceful critique to date of philosophies that reject objects as a primary reality. All such rejections are tainted by either an undermining or overmining approach to objects. In Chapters 2 and 3, he reviews his concepts of sensual and real objects. In the process, he attacks the prestige normally granted to philosophies of human access, which (...) Harman links for the first time to the already discredited Menos Paradox. In Chapters 4 through 7, Harman brings the reader up to speed on his interpretation of Heidegger, which culminates in a fourfold structure of objects linked by indirect causation. In Chapter 8, he speculates on the implications of this theory for the debate over panpsychism, which Harman both embraces and rejects. In Chapters 9 and 10, he introduces the term ontography as the study of the different possible permutations of objects and qualities, which he simplifies with easily remembered terminology drawn from standard playing cards.

We humans tend to believe that things are only real in as much as we perceive them, an idea reinforced by modern philosophy, which privileges us as special, radically different in kind from all other objects. But as Graham Harman, one of the theory's leading exponents, shows, Object-Oriented Ontology (OOO) rejects the idea of human specialness: the world, he states, is clearly not the world as manifest to humans. "To think a reality beyond our thinking is not nonsense, but obligatory." (...) At OOO's heart is the idea that objects--whether real, fictional, natural, artificial, human, or non-human--are mutually autonomous. This core idea has significance for nearly every field of inquiry which is concerned in some way with the systematic interaction of objects, and the degree to which individual objects resist full participation in such systems. In this brilliant new introduction, Graham Harman lays out OOO's history, ideas, and impact, taking in art and literature, politics and natural science along the way. From Sherlock Holmes, unicorns, and videogames to Dadaism, Voltaire, and string theory, this book will change the way you understand everything. (shrink)

Non-moral ignorance can exculpate: if Anne spoons cyanide into Bill's coffee, but thinks she is spooning sugar, then Anne may be blameless for poisoning Bill. Gideon Rosen argues that moral ignorance can also exculpate: if one does not believe that one's action is wrong, and one has not mismanaged one's beliefs, then one is blameless for acting wrongly. On his view, many apparently blameworthy actions are blameless. I discuss several objections to Rosen. I then propose an alternative view on which (...) many agents who act wrongly are blameworthy despite believing they are acting morally permissibly, and despite not having mismanaged their moral beliefs.1.

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)

I have been supposing that for the theory of reasoning, explicit belief is an all-or-nothing matter, I have assumed that, as far as principles of reasoning are concerned, one either believes something explicitly or one does not; in other words an appropriate "representation" is either in one's "memory" or not. The principles of reasoning are principles for modifying such all-or-nothing representations. This is not to deny that in some ways belief is a matter of degree. For one thing implicit belief (...) is certainly a matter of degree, since it is a matter of how easily and automatically one can infer something from what one believes explicitly. Furthermore, explicit belief is a matter of degree in the sense that one believes some things more strongly than others. Sometimes one is only somewhat inclined to believe something, sometimes one is not sure what to believe, sometimes one is inclined to disbelieve something, sometimes one is quite confident something is not so, and so forth.

Suppose you believe you’re morally required to φ‎ but that it’s not a big deal; and yet you think it might be deeply morally wrong to φ‎. You are in a state of moral uncertainty, holding high credence in one moral view of your situation, while having a small credence in a radically opposing moral view. A natural thought is that in such a case you should not φ‎, because φ‎ing would be too morally risky. The author argues that this (...) natural thought is misguided. If φ‎ing is in fact morally required, then you should φ‎, and this is so even taking into account your moral uncertainty. The author argues that if the natural thought were correct, then being caught in the grip of a false moral view would be exculpatory: people who do morally wrong things thinking they are acting morally rightly would be blameless. But being caught in the grip of a false moral view is not exculpatory. So the natural thought is false. The author develops the claim that you should act as morality actually requires as a candidate answer to the question “how should one act in the face of moral uncertainty?” This answer has been dismissed in discussion up to this point. The author argues that not only is this answer a serious contender; it is the correct answer. (shrink)

What objects exist in the social world and how should we understand them? Is a specific Pizza Hut restaurant as real as the employees, tables, napkins and pizzas of which it is composed, and as real as the Pizza Hut corporation with its headquarters in Wichita, the United States, the planet Earth and the social and economic impact of the restaurant on the lives of its employees and customers? In this book the founder of object-oriented philosophy develops his approach in (...) order to shed light on the nature and status of objects in social life. While it is often assumed that an interest in objects amounts to a form of materialism, Harman rejects this view and develops instead an “immaterialist” method. By examining the work of leading contemporary thinkers such as Bruno Latour and Levi Bryant, he develops a forceful critique of ‘actor-network theory’. In an extended discussion of Leibniz’s famous example of the Dutch East India Company, Harman argues that this company qualifies for objecthood neither through ‘what it is’ or ‘what it does’, but through its irreducibility to either of these forms. The phases of its life, argues Harman, are not demarcated primarily by dramatic incidents but by moments of symbiosis, a term he draws from the biologist Lynn Margulis. This book provides a key counterpoint to the now ubiquitous social theories of constant change, holistic networks, performative identities, and the construction of things by human practice. It will appeal to anyone interested in cutting-edge debates in philosophy and social and cultural theory. (shrink)

The current fashions in both analytic and continental philosophy are staunchly anti-metaphysical. There is supposedly no way to talk about the world itself — the philosopher is confined to antiseptic discussions of language, or of other modes of human access to the world. In this provocative work, Graham Harman expands the discussion from his previous book, Tool-Being, arguing for a theory of "the carpentry of things" — a more accessible way of viewing the world that incorporates ideas from Husserl, Levinas, (...) Lingis, and other philosophers. (shrink)

Martin Heidegger (1889–1976) influenced the work of such diverse thinkers as Sartre and Derrida. In Tool-Being, Graham Harman departs from the prevailing linguistic approach to analytic and continental philosophy in favor of Heideggerian object-oriented research into the secret contours of objects. Written in a colorful style, it will be of interest to anyone open to new trends in present-day philosophy.

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.

Continental philosophy has entered a new period of ferment. The long deconstructionist era was followed with a period dominated by Deleuze, which has in turn evolved into a new situation still difficult to define. However, one common thread running through the new brand of continental positions is a renewed attention to materialist and realist options in philosophy. Among the leaders of the established generation, this new focus takes numerous forms. It might be hard to find many shared positions in the (...) writings of Badiou, DeLanda, Laruelle, Latour, Stengers, and Žižek, but what is missing from their positions is an obsession with the critique of written texts. All of them elaborate a positive ontology, despite the incompatibility of their results. Meanwhile, the new generation of continental thinkers is pushing these trends still further, as seen in currents ranging from transcendental materialism to the London-based speculative realism movement to new revivals of Derrida. As indicated by the title The Speculative Turn, the new currents of continental philosophy depart from the text-centered hermeneutic models of the past and engage in daring speculations about the nature of reality itself. This anthology assembles authors, of several generations and numerous nationalities, who will be at the centre of debate in continental philosophy for decades to come. (shrink)

The non-identity problem concerns actions that affect who exists in the future. If such an action is performed, certain people will exist in the future who would not otherwise have existed: they are not identical to any of the people who would have existed if the action had not been performed. Some of these actions seem to be wrong, and they seem to be wrong in virtue of harming the very future individuals whose existence is dependent on their having been (...) performed. The problem arises when it is argued that the actions do not harm these people—because the actions do not make them worse off than they would otherwise be.1 Consider: Radioactive Waste Policy: We are trying to decide whether to adopt a permissive radioactive waste policy. This policy would be less inconvenient to us than our existing practices. If we enact the newly-proposed policy, then we will cause there to be radioactive pollution that will cause illness and suffering. However, the policy will have such significant effects on public policy and industry functioning, that different people will exist in the future depending on whether we enact the policy. Two things should be emphasized. First, the illness and suffering caused will be very serious: deformed babies, children with burns from acid rain, and adults dying young from cancer. Second, the policy will affect who will exist in the future because our present practices invade people’s everyday lives, for example by affecting recycling practices in the home; these practices will change if the policy is adopted. Furthermore, whether we adopt the policy will determine which plants are built where, what jobs are available, and what trucks are on the road. These effects will create small differences in everyone’s lives which ultimately affect who meets whom and who conceives with whom, or at least when people conceive. This affects who exists in the future. (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.

Quentin Meillassoux has been described as the most rapidly prominent French philosopher in the Anglophone world since Jacques Derrida in the 1960s. With the publication of After Finitude (2006), this daring protege of Alain Badiou became one of the world's most visible younger thinkers. In this book, his fellow Speculative Realist, Graham Harman, assesses Meillassoux's publications in English so far. Also included are an insightful interview with Meillassoux and first-time translations of excerpts from L'Inexistence divine (The Divine Inexistence), his famous (...) but still unpublished major book.

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)

Does it ever happen that there are things we shouldn’t do and the reasons we shouldn’t do them are moral reasons, yet doing them is not morally wrong? Surprisingly, yes. I argue for a category that has not been recognized by moral theorists: morally permissible moral mistakes. Sometimes a supererogatory action is the thing a person should do; in failing to act, one makes a morally permissible moral mistake. Recognizing the category of morally permissible moral mistakes solves a puzzle about (...) supererogation, expands the universe of possible moral views, and shows some apparently inconsistent moral views to be consistent.

Some experiences are transformative in that it is impossible to imagine experiencing them until one experiences them. It has been argued that pregnancy and parenthood are like that, and that therefore one cannot make a rational decision whether to become a mother. I argue that pregnancy and parenthood are not like that; but that if even if they are, a woman can still make a rational decision by relying on testimony about the value of these experiences. I then discuss an (...) objection that such testimony will be unreliable because parents will reflect on their being glad that their children exist, and will not realize that it’s reasonable to be glad their children exist even if the parents’ lives are thereby worse. I argue that despite this possible route to unreliable testimony, in general it is reasonable to rely on others’ testimony about the value of their lives. (shrink)

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)
