    In “Armchair Luck” (2007a), Nenad Miščević argues that Duncan Pritchard’s safe-true-belief anti-luck epistemology cannot rule out a priori veritic luck. Since a priori necessary truths are true in all possible worlds, Pritchard’s safety condition is satisfied in clear cases of knowledge-destroying a priori veritic luck. Thus, Pritchard’s modal anti-luck epistemology is mistaken. Nenad’s diagnosis is that Pritchard puts too much focus on the world and not enough focus on the epistemic agent. The …Read more

    Keith Lehrer (2019) identified the significant role played by exemplarization—a distinctive kind of representation of experience—in justification and defense of knowledge claims, including in the process of scientific change. He also highlighted the freedom of choice involved in the use of exemplarization in scientific contexts (Lehrer 2024). In this paper, I build on these insights and consider the roles of exemplarization in two notable tools of scientific research: electron and probe microsco…Read more

    Keith Lehrer has championed two types of reflexive phenomena that are sometimes thought to be problematic or impossible: exemplar representation (which seems to involve representations that represent themselves) and explanatory loops (which involve principles that explain themselves). My aim here is to distinguish several varieties of such phenomena, then determine which of them are present in Lehrer’s philosophy and whether they are possible or not.

    In this paper I take up two points that Keith Lehrer has made about the hard problem of consciousness. First, he argues that the mistaken impression that there is a hard problem results from a faulty metaphysics of properties. If properties are understood as tropes rather than as universals, the alleged hard problem goes away. Second, he argues that the integration of phenomenal properties–understood as tropes rather than as universals–does not pose a particularly difficult problem for the mater…Read more

    Keith Lehrer has had a major influence on contemporary epistemology, and he has played a vital role in renewing interest in the philosophy of Thomas Reid. Not coincidentally, the same type of common sense epistemological orientation as we find in Reid is evident in Lehrer’s epistemological writings, including in his most recent book, Exemplars of Truth. This chapter begins with a brief appreciation of both Lehrer and Reid, indicating some of the distinctive – and, I think, attractive -- features…Read more

    Foundationalism and coherentism are typically seen as competing views. I argue that there is a way of fusing them together. A key principle of coherentism is that there can be no justification without meta-justification. It tells us that, when we form beliefs on the basis of perception, they are unjustified unless we have justification for taking perception to be reliable. This principle seems to make basic beliefs—beliefs whose justification doesn’t come from other beliefs—impossible. I argue t…Read more

    Beyond Coherentism
    In Mylan Engel Jr & Joe Campbell (eds.), The Philosophy of Keith Lehrer: Essays on Knowledge, Consciousness, and Freedom, Springer. pp. 53-62. 2025.
    I argue that Lehrer’s account of personal justification does not match what we normally mean when we say that a person has a justified belief. It’s too subjective. According to Lehrer’s account of justification, a person could be justified in believing in astrology or that the earth was created a thousand years ago. His account of knowledge suffers from a similar defect. According to it, a person could know that someone in his office owns a Ferrari based on misleading evidence offered by another…Read more

    In both editions of his Theory of Knowledge (1990, 169–70 and 2000, 196), Keith Lehrer presents a case of a racist who becomes a racist medical doctor. Lehrer took the case to show (contrary to others’ arguments) that beliefs do not have to be based on the evidence in order to be justified, or count as knowledge. But there has been a mixture of responses to Lehrer’s thought experiment: not everyone who has considered the case has been ready to draw the same conclusions from it as Lehrer did. In …Read more

    In Exemplars of Truth, Keith Lehrer presents an impressive new epistemological theory. He continues to emphasize that knowledge and epistemic justification depend upon the capacity to rely upon a background system of beliefs, preference, and reasoning in a defense against potential objections. New to his theory is an attempt to explain how experience dynamically affects one’s background system by a process of exemplarization and generalization. Lehrer resists characterizing his view as foundatio…Read more

    In this chapter, I explore three ways our epistemic relationships with ourselves can be damaged by epistemic injustice. First, we can be blocked from a proper understanding of ourselves by conflicts between our own experiences and a dominant narrative. Jennifer Lackey has argued that extreme examples of this conflict can violate our “right to be known.” Second, continued denial of one’s own experiences by the larger culture can undermine self-trust. The central importance of self-trust can be ap…Read more

    I begin with appreciation to an editor of the current volume Mylan Engel. Now I have the chance to express gratitude to him for having arranged conferences about my work in progress, that, with any defects remaining, resulted in improving the final version of Ultimate Freedom: Beyond Free Will (2024). I am also grateful to another editor of the current volume Joseph Campbell for encouraging my latest work on freedom by organizing an APA meeting to discuss that work and to develop it within his p…Read more

    In this essay, I argue that Keith Lehrer’s account of freedom of choice, when allied to the Performance/Competence distinction commonly deployed in Cognitive Science helps us distinguish the human capacity for freedom, which looks free and “uncaused”, as Sartre influentially puts it in Being & Nothingness, from the external/performance aspects of freedom. Analytic philosophers have been hitherto preoccupied with the latter, performance aspect of freedom.Attending to the internal aspect, that is,…Read more

    In Ultimate Freedom: Beyond Free Will, Keith Lehrer remarks that he was sceptical of Carl Sagan’s claim that some of our responses are controlled by the reptilian part of the brain (2024, 30). I was equally sceptical of Lehrer’s claim that reason is the hero of free choice (2024, 11). My reaction to reading about power preferences was to think that I rarely have such preferences, and that the contexts in which I do have them comprise a fairly limited and mundane part of my life. Further, I don’t…Read more

    In UltimateFreedom: Beyond Free Will (2024), Keith Lehrer contends that human beings possess a unique metamental capacity for robust freedom of choice—a capacity not possessed by any other animals. Lehrer argues that when a person S has a power preference concerning option A and that power preference is the ultimate explanation of S’s choosing A, then S’s choosing A is free in the sourcehood (“it’s up S”), leeway (“S could have chosen otherwise”), and agency (“agent causation”) senses of freedom…Read more

    In my book An Essay on Free Will I present and defend several versions of the “Consequence Argument” for the incompatibility of free will and determinism. In his recent Ultimate Freedom: Beyond Free Will, Keith Lehrer gives two counter-arguments to the Consequence Argument—that is, arguments for the conclusion that the Consequence Argument is unsound. One of these counter-arguments (“Lehrer’s Principal Argument”) contends that one of the premises of the Consequence Argument—to wit, that no one i…Read more

    In Ultimate Freedom, Keith Lehrer presents his most comprehensive analysis of the nature of free will and its related concepts such as freedom, autonomy, free choice, preferences, and power preferences. It is in significant part a synthesis of his many previously published works on the topic stretching over several decades, though it contains considerable elaboration of his previous thinking. In particular, he both epistemologizes and metamentalizes his analysis of free will to a greater extent …Read more

    In Ultimate Freedom: Beyond Free Will, Keith Lehrer offers a defense of the consistency claim: the compatibility of freedom of choice and scientific laws covering all choice. Ultimate Freedom is also a book about scientific law and explanation, and Lehrer proposes a view in contrast to the covering-law model promoted by Carl Hempel. The covering-law model lends support to the determinism-explanation assumption: given determinism, there is an ultimate explanation of human choice and action in ter…Read more

    In this essay, I set out the main lines of Keith Lehrer’s account of freedom of choice in his latest book, Ultimate Freedom: Beyond Free Will, drawing attention to what I see as its most interesting components. I suggest some extended lines of inquiry worthy of further exploration, including questions concerning manipulation and the notion of ultimate preference.

    In his forthcoming Ultimate Freedom: Beyond Free Will, Keith Lehrer offers an account of freedom which he calls “ultimate freedom.” Since Lehrer’s account offers only sufficient but not necessary conditions for freedom, it remains an open question as to whether actions that are overlooked by his account should also be considered free. In this essay, I will address this question by examining what concepts of freedom we have interests in endorsing for the purpose of practical reasoning. In my theo…Read more

    A stalemate exists between two metaphysical models of freedom. Where sourcehood is a matter of acting in the right sort of way (e.g., autonomously or reasons-responsively) and leeway is a matter of being able to act otherwise in the right sort of way, leeway models hold that we act freely just in case we act with sourcehood and leeway. On the opposing side, source models hold that we act freely just in case we act with sourcehood. Exposing a false choice between these standard models, this essay…Read more

    Introduction
    In Mylan Engel Jr & Joe Campbell (eds.), The Philosophy of Keith Lehrer: Essays on Knowledge, Consciousness, and Freedom, Springer. pp. 1-30. 2025.
    In his sixty-plus years of publishing philosophy, Keith Lehrer has made groundbreaking contributions to epistemology (developing and defending a coherence theory of justification and knowledge), to the free will debate (introducing, critiquing, and defending compatibilism), and to philosophy of mind (defending metamentalism). Those working in these respective fields tend to be quite familiar with Lehrer’s contributions to their own field, but less familiar with his work in these other fields. We…Read more

    Developing an objective measure of knowledge of factory farming
    with Adam Feltz, Jacob N. Caton, Zac Cogley, Silke Feltz, Ramona Ilea, L. Syd M. Johnson, and Tom Offer-Westort
    Philosophical Psychology 37 (2). 2022.
    Knowledge of human uses of animals is an important, but understudied, aspect of how humans treat animals. We developed a measure of one kind of knowledge of human uses of animals – knowledge of factory farming. Studies 1 (N = 270) and 2 (N = 270) tested an initial battery of objective, true or false statements about factory farming using Item Response Theory. Studies 3 (N = 241) and 4 (N = 278) provided evidence that responses to a 10-item Knowledge of Factory Farming Scale predicted a reduction…Read more

    Epistemology and the Ethics of Animal Experimentation
    In Jennifer Lackey (ed.), Applied Epistemology, Oxford University Press. pp. 67-96. 2021.
    In this chapter, Mylan Engel Jr. argues that animal experimentation is neither epistemically nor morally justified and should be abolished. Engel argues that the only serious attempt at justifying animal experimentation is the benefits argument, according to which animal experiments are justified because the benefits that humans receive from the experiments outweigh the costs imposed on the animal subjects. According to Engel, the benefits we allegedly receive from animal-based biomedical resear…Read more

    This book contains eighteen original essays engaging with Keith Lehrer’s contributions to philosophy. The first nine chapters focus on Lehrer’s work in epistemology and philosophy of mind. These chapters examine the role of meta-justification in Lehrer’s (and Thomas Reid’s) epistemology, explore the epistemological significance of self-trust and how to restore self-trust to victims of epistemic injustice, challenge Lehrer’s solution to the hard problem of consciousness, question Lehrer’s account…Read more

    Internalism, the Gettier Problem, and Metaepistemological Skepticism
    Grazer Philosophische Studien 60 (1): 99-117. 2000.
    When it comes to second-order knowledge (i.e. knowing that one knows), internalists typically contend that when we know that p, we can, by reflecting, directly know that we are knowing it. Gettier considerations are employed to challenge this internalistic contention and to make out a prima facie case for internalistic metaepistemological skepticism, the thesis that no one ever intemalistically knows that one internalistically knows that p. In particular, I argue that at the metaepistemological …Read more

    Coarsening Brand on Events, while Proliferating Davidsonian Events
    Grazer Philosophische Studien 47 (1): 155-183. 1994.
    A course-grained theory of event individuation is defended by arguing that events are spatiotemporal particulars with an ontological affinity to coarse-grained physical objects and by demonstrating that the metalinguistic correlate to one set of adequate identity conditions for events is most plausibly iterpreted as coarsely individuating events. Such coarse-grained events, it is argued, do admit of divisibility proliferation, much like the proliferation of physical objects entailed by Goodman's…Read more
