In this impressive second edition of Theory of Knowledge, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the traditional definition of knowledge as justified true belief, Lehrer explores the truth, belief, and justification conditions on the way to a thorough examination of foundation theories of knowledge,the work of Platinga, externalism and naturalized epistemologies, internalism and modern coherence theories, contextualism, and recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes that (...) external factors must be matched by appropriate internal factors to yield knowledge. This match of internal and external factors follows from Lehrer’s new coherence theory of undefeated justification. In addition to doing justice to the living epistemological traditions, the text smoothly integrates several new lines that will interest scholars. Also, a feature of special interest is Lehrer’s concept of a justification game.This second edition of Theory of Knowledge is a thoroughly revised and updated version that contains several completely new chapters. Written by a well-known scholar and contributor to modern epistemology, this text is distinguished by clarity of structure, accessible writing, and an elegant mix of traditional material, contemporary ideas, and well-motivated innovation.

Believing that p, assuming that p, and imagining that p involve regarding p as true—or, as we shall call it, accepting p. What distinguishes belief from the other modes of acceptance? We claim that conceiving of an attitude as a belief, rather than an assumption or an instance of imagining, entails conceiving of it as an acceptance that is regulated for truth, while also applying to it the standard of being correct if and only if it is true. We argue (...) that the second half of this claim, according to which the concept of belief includes a standard of correctness, is required to explain the fact that the deliberative question whether to believe that p is transparent to the question whether p. This argument raises various questions. Is there such a thing as deliberating whether to believe? Is the transparency of the deliberative question whether to believe that p the same as the transparency of the factual question whether I do believe that p? We will begin by answering these questions and then turn to a series of possible objections to our argument. (shrink)

I discuss Ruth Marcus' conception of beliefs as dispositional states related to possible states of affaires. While I agree with Marcus that this conception accounts for the necessary distinction between belief and linguistic assent, I argue that the relationship between dispositional beliefs and our assent attitudes is more complex, and should include other mental states, such as acceptances, which, although they contain voluntary elements, are further layers of dispositional doxastic attitudes.

The abstract structure of inquiry - the process of acquiring and changing beliefs about the world - is the focus of this book which takes the position that the "pragmatic" rather than the "linguistic" approach better solves the philosophical problems about the nature of mental representation, and better accounts for the phenomena of thought and speech. It discusses propositions and propositional attitudes (the cluster of activities that constitute inquiry) in general and takes up the way beliefs change in response to (...) potential new information, suggesting that conditional propositions should be understood as projections of epistemic policies onto the world.Robert C.

In this paper we defend the doxastic conception of delusions against the metacognitive account developed by Greg Currie and collaborators. According to the metacognitive model, delusions are imaginings that are misidentified by their subjects as beliefs: the Capgras patient, for instance, does not believe that his wife has been replaced by a robot, instead, he merely imagines that she has, and mistakes this imagining for a belief. We argue that the metacognitive account is untenable, and that the traditional conception of (...) delusions as beliefs should be retained. (shrink)

Chris Frith has argued that a loss of the sense of agency is central to schizophrenia. This suggests a connection between hallucinations and delusions on the one hand, and the misidentification of the subject’s imaginings as perceptions and beliefs on the other. In particular, understanding the mechanisms that underlie imagination may help us to explain the puzzling phenomena of thought insertion and withdrawal. Frith sometimes states his argument in terms of a loss of metarepresentational capacity in schizophrenia. I argue that (...) this formulation is unhelpful. (shrink)

Recreative Minds develops a philosophical theory of imagination that draws upon the latest work in psychology. This theory illuminates the use of imagination in coming to terms with art, its role in enabling us to live as social beings, and the psychological consequences of disordered imagination. The authors offer a lucid exploration of a fascinating subject.

In this incisive new book one of Britain's most eminent philosophers explores the often overlooked tension between voluntariness and involuntariness in human cognition. He seeks to counter the widespread tendency for analytic epistemology to be dominated by the concept of belief. Is scientific knowledge properly conceived as being embodied, at its best, in a passive feeling of belief or in an active policy of acceptance? Should a jury's verdict declare what its members involuntarily believe or what they voluntarily accept? And (...) should statements and assertions be presumed to express what their authors believe or what they accept? Does such a distinction between belief and acceptance help to resolve the paradoxes of self-deception and akrasia? Must people be taken to believe everything entailed by what they believe, or merely to accept everything entailed by what they accept? Through a systematic examination of these problems, the author sheds new light on issues of crucial importance in contemporary epistemology, philosophy of mind, and cognitive science. (shrink)

This collection of 17 essays by the author offers a comprehensive theory of mind, encompassing traditional issues of consciousness and free will.

This book explores the idea that we have two minds - one automatic, unconscious, and fast, the other controlled, conscious, and slow. It brings together leading researchers on dual-process theory to summarize the state of the art highlight key issues, present different perspectives, and provide a stimulus to further work.

In this collection of essays, Lehrer argues that freedom, rationality, consensus, and knowledge depend on "metamental" operations--thoughts about thoughts--and are impossible without them. Metamental operations provide for our optionality, plasticity, and most of all, for the evaluation and control of lower-level information. The human mind, he argues, is essentially a metamind.

The study of the feeling of knowing may have implications for some of the metatheoretical issues concerning consciousness and control. Assuming a distinction between information-based and experience-based metacognitive judgments, it is argued that the sheer phenomenological experience of knowing (''noetic feeling'') occupies a unique role in mediating between implicit-automatic processes, on the one hand, and explicit-controlled processes, on the other. Rather than reflecting direct access to memory traces, noetic feelings are based on inferential heuristics that operate implicitly and unintentionally. Once (...) such heuristics give rise to a conscious feeling that feeling can then affect controlled action. Examination of the cues that affect noetic feelings suggest that not only do these feelings inform controlled action, but they are also informed by feedback from the outcome of that action. (shrink)

I argue that in order to solve the main difficulties confronted by the classical versions of the causal theory of action, it is necessary no just to make room for intentions, considered as irreducible to complexes of beliefs and desires, but also to distinguish among several types of intentions. I present a three-tiered theory of intentions that distinguishes among future-directed intentions, present-directed intentions and motor intentions. I characterize each kind of intention in terms of its functions, its type of content, (...) its dynamics and the rationality and time constraints that bear on it. I then try to show how the difficulties encountered by the causal theory can be solved within this new framework. 1. (shrink)

This paper explores the sense in which belief "aims at the truth". In this course of this exploration, it discusses the difference between belief and make-believe, the nature of psychoanalytic explanation, the supposed "normativity of meaning", and related topics.

Mind and Supermind offers an alternative perspective on the nature of belief and the structure of the human mind. Keith Frankish argues that the folk-psychological term 'belief' refers to two distinct types of mental state, which have different properties and support different kinds of mental explanation. Building on this claim, he develops a picture of the human mind as a two-level structure, consisting of a basic mind and a supermind, and shows how the resulting account sheds light on a number (...) of puzzling phenomena and helps to vindicate folk psychology. Topics discussed include the function of conscious thought, the cognitive role of natural language, the relation between partial and flat-out belief, the possibility of active belief formation, and the nature of akrasia, self-deception and first-person authority. This book will be valuable for philosophers, psychologists and cognitive scientists. (shrink)

The thesis that mental content is normative is ambiguous and has many forms. This article deals only with the thesis that normativity is connected to our mental attitudes rather than with the content of the attitudes, and more specifically with the view that it is connected to belief. A number of writers have proposed various versions of a ‘norm of truth’ attached to belief. I examine various versions of this claim, and defend it against recent criticisms according to which this (...) norm lacks normative force, that it violates the principle that ‘ought implies can,’ and that it is viciously circular. I defend the view that we should distinguish the statement of the objective norm and the way it is regulated, and that this distinction can answer most of the criticisms of the norm of truth for belief.

The eminent philosopher Keith Lehrer offers an original and distinctively personal view of central aspects of the human condition, such as reason, knowledge, wisdom, autonomy, love, consensus, and consciousness. He argues that what is uniquely human is our capacity for evaluating our own mental states (such as beliefs and desires), and suggests that we have a system for such evaluation which allows the resolution of personal and interpersonal conflict. The keystone in this system is self-trust, on which reason, knowledge, and (...) wisdom are grounded. (shrink)

In this paper the problem of the relation between belief and acceptance is discussed in view of recent literature on the topic. Belief and acceptance are characterized in terms of a number of properties, which show both the similarities and the dissimilarities between these notions. In particular it is claimed - contrary to some recently expressed views - that acceptance need not be intentional action and that the differences between belief and acceptance do not boil down to the simple view (...) that acceptance, contrary to belief, is based on the agent's direct exercise of his will. Acceptance which is not based on intentional action is shown in the paper to be especially closely related to belief, especially to linguistic belief. Thus if a person is in a non-intentional-ly acquired and held state of acceptance that something p, he also believes that p. Another general difference is that acceptance is language-dependent while there can be non-linguistic belief. Collective beliefs and acceptances are also briefly discussed in the paper Among other things, it is noted that the notion of wide as contrasted with truth-oriented, narrow acceptance is central in the collective case.

For any proposition P, it may sometimes occur that a person is not quite accurately describable as believing that P, nor quite accurately describable as failing to believe that P. Such a person, I will say, is in an "in-between state of belief." This paper argues for the prevalence of in-between states of believing and asserts the need for an account of belief that allows us intelligibly to talk about in-between believing. It is suggested that Bayesian and representationalist approaches are (...) inadequate to the task and that a Rylean dispositional account of belief might do the trick. (shrink)

It is argued that the intuitively sanctioned distinction between beliefs and non-belief states that play a role in the proximate causal history of beliefs is a distinction worth preserving in cognitive psychology. The intuitive distinction is argued to rest on a pair of features exhibited by beliefs but not by subdoxastic states. These are access to consciousness and inferential integration. Harman's view, which denies the distinction between beliefs and subdoxastic states, is discussed and criticized.

Belief is not a unified phenomenon. In this paper I argue, as a number of other riters argue, that one should distinguish a variety of belief-like attitudes: believing proper - a dispositional state which can have degrees - holding true - which can occur without understanding what one believes - and accepting - a practical and contextual attitude that has a role in deliberation and in practical reasoning. Acceptance itself is not a unified attitude. I explore the various relationships and (...) differences between these doxastic attitudes, and claim that although acceptance is distinct from belief, it rests upon it, and is therefore a species of belief.

This article evaluates the scientific credentials of a distinction that is frequently endorsed by scientists who study human reasoning, between so-called “System 1” and “System 2”. The paper argues that one aspect of what is generally intended by this distinction is real. In particular, there is a real distinction between intuitive and reflective cognitive processes. But this distinction fails to line up with many of the other properties attributed to System 1 and System 2. Accordingly, the paper argues that the (...) latter distinction is not real, and should be abandoned. (shrink)
