In this paper, we review KeithLehrer’s account of the basing relation, with particular attention to the two cases he offered in support of his theory, Raco (Lehrer, Theory of knowledge, 1990; Theory of knowledge, (2nd ed.), 2000) and the earlier case of the superstitious lawyer (Lehrer, The Journal of Philosophy, 68, 311–313, 1971). We show that Lehrer’s examples succeed in making his case that beliefs need not be based on the evidence, in order to (...) be justified. These cases show that it is the justification (rather than the belief) that must be based in the evidence. We compare Lehrer’s account of basing with some alternative accounts that have been offered, and show why Lehrer’s own account is more plausible. (shrink)
In this impressive second edition of Theory of Knowledge, KeithLehrer 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.

In this important new text, KeithLehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the accepted 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, externalism and naturalized epistemologies, internalism and modern coherence theories as well as recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes that external factors (...) must be matched by appropriate internal ones to yield knowledge. Readers of Professor Lehrer's earlier book _Knowledge_ will want to know that this text adopts the framework of that classic text. But _Theory of Knowledge_ is a completely rewritten and updated version of that book that has been simplified throughout for student use. (shrink)
The eminent philosopher KeithLehrer 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)
The recently offered, Purported counter-Examples to justified, True belief analyses of knowledge are looked at with some care and all found to be either incoherent or inconclusive. It is argued that justified, True belief analyses are based on sound insight into the concept of knowledge. The distinction between having been justified in claiming to know something and actually having known it is used in an effort to get the discussion of knowledge back on the right track.
A central issue in epistemology concerns the connection between truth and justification. The burden of our paper is to explain this connection. Reliabilism, defended by Goldman, assumes that the connection is one of reliability. We argue that this assumption is too strong. We argue that foundational theories, such as those articulated by Pollock and Chisholm fail to elucidate the connection. We consider the potentiality of coherence theories to explain the truth connection by means of higher level convictions about probabilities, which (...) we call doxastic ascent, and defend such a theory. Our defense appeals to the work of Reid and contemporary cognitive psychology in order to account for the psychological reality of higher level evaluations. (shrink)
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 human mind is essentially a metamind. Autonomy, knowledge, preference, acceptance, consciousness, and the content of thought all incorporate metamental ascent to a higher level beyond first level belief and desire. The primary function or role of metamental ascent is conflict resolution and higher order evaluation. An infinite regress of metamental ascent is avoided by a mental loop of keystone states which refer back to themselves yielding autonomy and knowledge without paradox. The metamental loop is, moreover, compatible with materialism, even (...) eliminative materiahsm. Vector activation in the brain averages neural impulses, and conflict resolution in the brain, like interpersonal conflict resolution, is obtained from weighted averaging. The resolution of the conflict is a fixed point vector of integrative weights which yields itself back forming a neural loop. Thus, neurophysiology recapitulates metamentality. (shrink)

Memory sometimes yields knowledge and sometimes does not. It is, however, natural to suppose that i f a man remembers that p, then he knows that p and formerly knew that p. Remembering something is plausibly construed as a f o rm of knowing something which one has not forgotten and which one knew previously. We argue, to the contrary, that this thesis is false. We present four counterexamples to the thesis that support a different analysis of remembering. We propose (...) that a person remembers that p (at t) if and only if the thought or conviction that p comes from memory (at t) when, in fact, it is true that p. (shrink)
Intentionality is a mark of the mental, as Brentano (1874) noted. Any representation or conception of anything has the feature of intentionality, which informally put, is the feature of being about something that may or may not exist. Visual artworks are about something, whether something literal or abstract. The artwork is a mentalized physical object. Aesthetic experience of the artwork illustrates the nature of intentionality as we focus attention on the phenomenology of the sensory exemplar. This focus of attention on (...) the exemplar in aesthetic experience simultaneously exhibits what the intentional object is like and what our conception of it is like. The exemplar is Janus-faced, looking in one direction outward toward the objects conceived and in the other direction inward toward our conceiving of them. It shows us what intentionality is like and how we know it. (shrink)
Harry G. Frankfurt has presented a case of a counterfactual intervener CI with knowledge and power to control an agent so he will do A. He concludes that if the agent prefers to do A and there is no intervention by CI, the agent has acted of his own free will and is morally responsible for doing A, though he lacked an alternative possibility. I consider the consequences for freedom and moral responsibility of CI having a complete plan P for (...) all actions of an agent, Lucky, who luckily has preferences that accord with P, and I extend the argument to all citizens of a land, Luckyland, who are like Lucky. I argue the citizens of Luckyland have free will but lack moral responsibility because of the connection between moral responsibility, reactive attitudes and future action. Furthermore, the presence of CI and his plan P may allow free will but is incompatible with freedom of preference. Preference concerns alternatives excluded by CI. I argue that a special higher order preference for the preference structure, a power preference, ends the regress of higher order preference and explains the first order preference. Causal determinism is compatible with freedom of preference explained by a power preference when a power preference would also explain an alternative preference. The remoteness argument for incompatibility fails because of a lack of transitivity causal explanation. The power preference is the self-explained source of freedom of preference. That basic freedom may be limited by government knowledge of our preferences, even if, like Lucky, our preferences do not provoke intervention and we conform of our own free will. (shrink)
This paper argues against the deductive reconstruction of scientific prediction, that is, against the view that in prediction the predicted event follows deductively from the laws and initial conditions that are the basis of the prediction. The major argument of the paper is intended to show that the deductive reconstruction is an inaccurate reconstruction of actual scientific procedure. Our reason for maintaining that it is inaccurate is that if the deductive reconstruction were an accurate reconstruction, then scientific prediction would be (...) impossible. (shrink)
Coherence with a background system yields justification which, when undefeated by error, becomes knowledge. Undefeated justification is knowledge. So I have argued. I have, however, changed my conception of the details of the background system, justification in terms of it and undefeated justification even if the intuitions that drive the analysis are the same. The background system, which I call an evaluation system, contains not only acceptances, as I originally proposed, but also preferences concerning acceptance and reasoning based on acceptance. (...) Justification consists of the capacity to meet objections to a target acceptance, including those an externalist might raise, in terms of the evaluation system. Undefeated justification is justification that remains when the evaluation system is cleansed of error. It is, therefore, the result of a systematic match of internal justification and the external truth. (shrink)
Chisholm held that some states of ourselves are self-presenting and provide a stopping place in the quest for justification. The justification we have for accepting that we are in those states is transparent to us in a way that enables us to answer questions about justification. Representation enables us to apprehend such self-presenting states through themselves in a representational loop. It is a loop of exemplarization wherein the state is used as an exemplar to represent the kind of state it (...) is. The result is that the representation of the state provides the subject with a kind of representation that loops back onto itself escaping the bondage of stratified mentality. This form of representation by exemplarization is shown to resolve problems and paradoxes concerning subjectivity, consciousness and the self raised by the writings of Hume, Kierkegaard, Ferrier, Sartre and Frank Jackson.
