Does ‘remembering that p’ entail ‘knowing that p’? The widely-accepted epistemic theory of memory answers affirmatively. This paper purports to reveal the tension between ETM and the prevailing anti-luck epistemology. Central to my argument is the fact that we often ‘vaguely remember’ a fact, of which one plausible interpretation is that our true memory-based beliefs formed in this way could easily have been false. Drawing on prominent theories of misremembering in philosophy of psychology, I will construct cases where the subject (...) vaguely remembers that p while fails to meet the safety condition, which imply either that ETM is false or that safety is unnecessary for knowledge. The conclusion reached in this paper will be a conditional: if veritic epistemic luck is incompatible with knowledge, then ‘remembering that p’ does not entail ‘knowing that p’. (shrink)

This paper purports to disprove an orthodox view in contemporary epistemology that I call ‘the epistemic conception of memory’, which sees remembering as a kind of epistemic success, in particular, a kind of knowing. This conception is embodied in a cluster of platitudes in epistemology, including ‘remembering entails knowing’, ‘remembering is a way of knowing’, and ‘remembering is sufficiently analogous to knowing’. I will argue that this epistemic conception of memory, as a whole, should be rejected insofar as we take (...) into account some putative necessary conditions for knowledge. It will be illustrated that while many maintain that knowing must be (1) anti-luck and (2) an achievement, the two conditions do not apply to remembering. I will provide cases where the subject successfully remembers that p but lacks knowledge that p for failing to meet the two putative conditions for knowledge. Therefore, remembering is not a kind of knowing but a sui generis cognitive activity. (shrink)

Epistemic absolutism is an orthodox view that propositional knowledge is an ungradable concept. Absolutism is primarily grounded in our ungradable uses of “knows” in ordinary language. This paper advances a thorough objection to the linguistic argument for absolutism. My objection consists of two parts. Firstly, arguments for absolutism provided by Jason Stanley and Julien Dutant will be refuted respectively. After that, two more general refutation-strategies will be proposed: counterevidence against absolutism can be found in both English and non-English languages; the (...) linguistic argument for absolutism is subject to a methodological mistake as the linguistic usages of “knows” cannot accurately reflect its conceptual nature. Therefore, we should give epistemic gradualism, as opposed to absolutism, a more serious consideration. (shrink)

Epistemic absolutism holds that knowledge‐that is ungradable, while epistemic gradualism argues the opposite. This paper purports to remodel the gradualism/absolutism debate. The current model initiated by Stephen Hetherington fails to capture the genuine divergence between the two views, which makes the debate equivocal, and the gradualist side lacks appeal. I propose that the remodeled debate should focus on whether knowledge‐that is a ‘threshold concept’ or a ‘spectrum concept’. That is, whether there is a threshold distinguishing knowledge from non‐knowledge. The reconstructed (...) model enjoys significant advantages as it enables the debate to be more balanced and philosophically interesting. (shrink)

I argue against mnemic reliabilism, an influential view that successful remembering must be produced by a reliable memory process. Drawing on empirical evidence from psychology and neuroscience, I refute mnemic reliabilism by demonstrating that: (1) patients with memory impairments (e.g., Alzheimer’s disease) can also successfully remember the past despite the unreliability of their corresponding memory processes; (2) some reliability-affecting factors (e.g., stress, divided attention, and insufficient encoding time) can render the memory processes of healthy individuals unreliable without preventing them from (...) occasionally resulting in successful remembering. Potential responses available for mnemic reliabilism are also evaluated. I show that those responses are susceptible to a challenge akin to the generality problem for process reliabilism. (shrink)

The core thesis of anti-luck epistemology is the incompatibility thesis, that is, knowledge is incompatible with veritic epistemic luck. Traditionally, anti-luck epistemologists hold that there are two distinct types of veritic epistemic luck, viz, intervening luck and environmental luck. The former occurs when something luckily intervenes between the subject’s belief and the target fact, which renders the subject’s belief luckily true. The latter can be found in cases where the subject’s belief is luckily true when she is in an unfriendly (...) epistemic environment. This paper purports to show that there is another long-neglected type of veritic epistemic luck—I name it ‘interpretative luck’. It refers to the type of luck occurring when the subject accidentally chooses the correct interpretation of evidence and thus her belief is luckily true. I will demonstrate that no proper reasons can support the incompatibility between interpretative luck and knowledge. Instead, the price for insisting this incompatibility would be unacceptably high. Therefore, the existence of interpretative luck falsifies the incompatibility thesis of anti-luck epistemology. (shrink)

The purpose of this paper is to provide a new solution to the radical sceptical paradox. A sceptical paradox purports to indicate the inconsistency within our fundamental epistemological commitments that are all seemingly plausible. Typically, sceptics employ an intuitively appealing epistemic principle (e.g., the closure principle, the underdetermination principle) to derive the sceptical conclusion. This paper will reveal a dilemma intrinsic to the sceptical paradox, which I refer to as the self-hollowing problem of radical scepticism. That is, on the one (...) hand, if the sceptical conclusion turns out to be true, then the epistemic principle employed by sceptics would lose its foundation of plausibility; on the other hand, if the sceptical conclusion does not follow, then the sceptical problem would not arise. In either case, the so-called sceptical paradox cannot be a genuine paradox. This new solution has three theoretical merits: it is undercutting, less theory-laden, and widely applicable. (shrink)

An epistemological orthodox view holds that knowing that p is an absolute ‘yes-or-no’ affair rather than something that comes in degrees. The rising epistemic gradualist theory challenges this orthodoxy by arguing that knowledge-that is a gradable concept. The predominant form of argument for gradualism in the current literature is the argument from component, according to which knowledge is gradable because its various components (e.g., justification, belief, truth) are gradable. I will show that the argument from components involves a non-sequitur: the (...) alleged gradability of knowledge’s components cannot ensure the gradability of knowledge per se. The crux of this logical lacuna lies in that the argument neglects the external gradability of knowledge, viz, there is no clear-cut threshold between knowledge and lack thereof. The lacuna can be mended by seeing knowledge-that as a spectrum concept such that a more complete gradualist picture can be achieved. (shrink)

Recently there has been extensive debate over whether “belief is weak”, viz, whether the epistemic standard for belief is lower than for assertion or knowledge. While most current studies focus on notions such as “ordinary belief” and “outright belief”, this paper purports to advance this debate by investigating a specific type of belief; memory belief. It is argued that (outright) beliefs formed on the basis of episodic memories are “weak” due to two forms of “entitlement inequality”. My key argument is (...) thus twofold. First, by rejecting the epistemic theory of memory, I argue that one can be entitled to belief but not to knowledge. Second, by scrutinising a recent defence of the belief norm of assertion, it will be demonstrated that belief is weaker than assertion, as long as we expect one to match words with deeds. (shrink)

A large portion of our knowledge seems to rest on our memories, while memory scepticism poses challenges to our memory knowledge. This paper will delve into different forms of memory scepticism. The goal of this paper is twofold: First, drawing on Moon (2017) and Frise (2022), I compare and criticize various forms of sceptical arguments provided by them. Meanwhile, the two most threatening arguments are picked out: the Russellian argument and the argument from doubtful reliability. Second, I demonstrate that the (...) two arguments are essentially based on the closure principle and the underdetermination principle, respectively, and hence, Pritchard’s biscopic anti-sceptical proposal is applicable. A Pritchardean solution to the problem of memory scepticism will then be sketched out. (shrink)

It is epistemological orthodoxy that the object of propositional knowledge is the truth of propositions. This traditional view is based on what I call the ‘KT-schema’, viz, ‘S knows that p, iff, S knows that “p” is true’. The purpose of this paper is to reject the KT-schema. By showing the paradoxical upshot of the KT-schema and providing counterexamples to the KT-schema, this paper argues that ‘knowing that p’ is more than ‘knowing that “p” is true’. Consequently, we shall rethink (...) the object problem of propositional knowledge – if knowing that p is not merely knowing that ‘p’ is true, then what is indeed the object of propositional knowledge? I will also attempt to solve this problem by proposing a complementary answer: knowing that p requires at least knowing the truth of p, plus, understanding the content of p. (shrink)

Epistemological disjunctivism argues that one can have perceptual knowledge that p in virtue of being in possession of factive and reflectively accessible rational support, e.g., one’s ‘seeing that p’. A well-known challenge to this view is the so-called basis problem of epistemological disjunctivism, which argues that one’s ‘seeing that p’ cannot constitute the rational support for one’s knowledge that p, as ‘seeing that p’ is just a way of ‘knowing that p’. The basis problem is taken to be based on (...) the entailment thesis, viz, ‘seeing that p’ entails ‘knowing that p’. Mainstream solutions to the basis problem take an approach rejecting the entailment thesis. This paper purports to reveal a common defect of those extant solutions. That is, they all fail to address the basis problem in the central domain of discussion of epistemological disjunctivism, i.e., what Pritchard refers to as ‘paradigmatic cases’. Moreover, even if they succeed in rejecting the entailment thesis in paradigmatic cases, they would also backfire on epistemological disjunctivism. (shrink)

An orthodox sceptical hypothesis claims that one’s belief that “I am not a brain-in-a-vat (BIV)” (or any other ordinary anti-sceptical belief) is insensitive. A form of sensitivity-based scepticism, can thus be constructed by combining this orthodox hypothesis with the sensitivity principle and the closure principle. Unlike traditional solutions to the sensitivity-based sceptical problem, this paper will propose a new solution—one which does not reject either closure or sensitivity. Instead, I argue that sceptics’ assumption that one’s ordinary anti-sceptical beliefs are insensitive (...) will give rise to self-contradiction. The orthodox sceptical hypothesis is thus revealed to be incoherent and arbitrary. Given that there is no coherent reason to presuppose our ordinary anti-sceptical beliefs to be insensitive, the argument for sensitivity-based scepticism can thus be blocked at a lower epistemological cost. (shrink)

An orthodox view in epistemology holds that propositional knowledge is an absolute ‘yes or no’ affair, viz, propositional knowledge is ungradable. Call this view epistemic absolutism. This thesis purports to challenge this absolutist orthodoxy and develop an underexplored position—epistemic gradualism, which was initially proposed by Stephen Hetherington. As opposed to epistemic absolutism, epistemic gradualism argues that propositional knowledge can come in degrees. This thesis will examine motivations for endorsing absolutism and then, drawing on Hetherington’s original objections to absolutism, prove that (...) absolutism is ill-grounded. In particular, I will explain why the primary ground for insisting absolutism, to wit, linguistic evidence from ordinary English language, fails to entail that knowledge-that is an ungradable concept. After that, I will revisit Hetherington’s two versions of gradualist theories—both will be revealed to be defective. Moreover, the current model of the debate between absolutism and gradualism constructed by Hetherington will give rise to an equivocal attitude towards the gradability of knowledge. That is, there is a prevailing equivocal view which agrees that knowledge can be improved by virtue of better justification but denies that knowledge is, by and large, a gradable concept. This thesis proposes to remodel the debate between absolutism and gradualism by basing it on a dispute about whether knowledge has a cut-off point distinguishing knowledge from everything that falls short of knowledge. Succinctly put, whether propositional knowledge has a threshold. It will be argued that gradualism, so interpreted, should deny that knowledge has a threshold, and treat knowledge as a spectrum concept analogous to ‘red’, ‘warm’, and so forth. The theoretical merits of this new model of the debate and the reconstructed gradualism will be shown. With a better-constructed gradualist account of knowledge in play, I will demonstrate how gradualism enjoys advantages over absolutism by illustrating gradualism’s potential applications in solving epistemological issues that absolutism finds difficult to address. For example, issues related to epistemic luck, faultless disagreements, scepticism, and the relationship between different types of knowledge. (shrink)

Relearning and remembering are usually seen as two distinct cognitive processes in contemporary philosophy of memory. In particular, relearning is sometimes regarded as a kind of memory error. This paper aims to address two questions. First, is relearning a kind of memory error? Second, how to draw a distinction (if any) properly between relearning and remembering? My answer to the first question is a conditional ‘yes’—it depends on whether relearning can be falsidical and whether metacognitive monitoring counts as a part (...) of memory process. My answer to the second question appeals to a gradualist account, according to which the distinction between relearning and remembering is not an absolute yes-or-no affair, but a matter of degrees.
