KNOWLEDGE EXTERNALISM

Abstract:  A popular counterexample directed against externalist epistemological views is that of an agent (Lehrer's "Truetemp" for example) whose beliefs are clearly neither justified nor known but that were generated in the manner that the externalist requires, thereby demonstrating externalism to be insufficient. In this essay I develop and defend an externalist account of knowledge – essentially an elaboration of Fred Dreske's information-theoretic account – that is not susceptible to those criticisms. I then briefly discuss the relationship between knowledge and justification.     

Coherence Theory of Knowledge: a Gradational Account

A satisfactory theory of knowledge in which the shortcomings of a pure externalist account are avoided and in which the Gettier problem is solved should consist in a combination of externalist and internalist components. The internalist component should guarantee that the epistemic subject has cognitive access to the justifying grounds of her belief. And the externalist component should guarantee that the justification of her belief does not depend on any false statement. Keith Lehrer's coherence theory of knowledge as undefeated justification is an example of such an internalist-externalist analysis of knowledge. But nevertheless, Lehrer's account leads to unintended results. Therefore, it is argued that a satisfactory coherence theory of knowledge must also be based on a gradual notion of systematic coherence.     

Colour Inversion Problems for Representationalism

In this paper I examine whether representationalism can account for various thought experiments about colour inversions. Representationalism is, at minimum, the view that, necessarily, if two experiences have the same representational content then they have the same phenomenal character. I argue that representationalism ought to be rejected if one holds externalist views about experiential content and one holds traditional externalist views about the nature of the content of prepositional attitudes. Thus, colour inversion scenarios are more damaging to externalist representationalist views than have been previously thought. More specifically, I argue that representationalists who endorse externalism about experiential content either have to become internalists about the content of prepositional attitudes or they have to adopt a novel variety of externalism about the content of prepositional attitudes. This novel type of prepositional attitude externalism is investigated. It can be seen that adopting it forces one to reject Putnam's and Burge's externalist considerations about the nature of the prepositional attitudes.     

Split-brain syndrome and extended perceptual consciousness

In this paper I argue that split-brain syndrome is best understood within an extended mind framework and, therefore, that its very existence provides support for an externalist account of conscious perception. I begin by outlining the experimental aberration model of split-brain syndrome and explain both: why this model provides the best account of split-brain syndrome; and, why it is commonly rejected. Then, I summarise Susan Hurley’s argument that split-brain subjects could unify their conscious perceptual field by using external factors to stand-in for the missing corpus callosum. I next provide an argument that split-brain subjects do unify their perceptual fields via external factors. Finally, I explain why my account provides one with an experimental aberration model which avoids the problems typically levelled at such views, and highlight some empirical predictions made by the account. The nature of split-brain syndrome has long been considered mysterious by proponents of internalist accounts of consciousness. However, in this paper I argue that externalist theories can provide a straightforward explanation of the condition. I therefore conclude that the ability of externalist accounts to explain split-brain syndrome gives us strong reason to prefer them over internalist rivals.     

What is What it’s Like? Introducing Perceptual Modes of Presentation

The central claim of this paper is that what it is like to see green or any other perceptible property is just the perceptual mode of presentation of that property. Perceptual modes of presentation are important because they help resolve a tension in current work on consciousness. Philosophers are pulled by three mutually inconsistent theses: representational externalism, representationalism, and phenomenal internalism. I throw my hat in with defenders of the first two: the externalist representationalists. We are faced with the problem of explaining away intuitions that favor phenomenal internalism. Perceptual modes of presentation account for what it is like to see properties in a way that accommodates those intuitions without vindicating phenomenal internalism itself. Perceptual MoPs therefore provide a new way of being an externalist representationalist.     

Some reflections on religious knowledge

The essay that follows considers two topics. After dealing with relevant preliminaries, it asks: (a) what differences are there in what must be done in order to tell whether there is any religious knowledge if an internalist evidentialist account of knowledge is true, from what must be done in order to tell whether there is any religious knowledge if an externalist reliabilist account of knowledge is true; and (b) does the best current externalist reliabilist account of knowledge require (or perhaps already implicitly contain) an internalist evidentialist element? Put in a nutshell, then, a belief has warrant for a person S only if that belief is produced in S by cognitive faculties functioning properly (subject to no dysfunction) in a cognitive environment that is appropriate for S’s kind of cognitive faculties, according to a design plant that is successfully aimed at truth … when a belief meets these conditions and does enjoy warrant, the degree of warrant it enjoys depends on the strength of the belief, the degree of firmness with which S holds it. This is intended as an account of the central core of our concept of warrant … [Warranted Christian Belief, 156; implicit in reference to a design plan here is another feature—that the belief is subject to no undefeated defeaters; such a belief, if true, constitutes knowledge.]     

Felix Culpa: Luck In Ethics And Epistemology

Luck threatens in similar ways our conceptions of both moral and epistemic evaluation. This essay examines the problem of luck as a metaphilosophical problem spanning the division between subfields in philosophy. I first explore the analogies between ethical and epistemic luck by comparing influential attempts to expunge luck from our conceptions of agency in these two subfields. I then focus upon Duncan Pritchard's challenge to the motivations underlying virtue epistemology, based specifically on its handling of the problem of epistemic luck. I argue that (1) consideration of the multifold nature of the problem of epistemic luck to an adequate account of human knowledge drives us to a mixed externalist epistemology; and (2) the virtue‐theoretical approach presents a particularly advantageous way of framing and developing a mixed externalist epistemology.     

A Phenomenal, Dispositional Account of Belief

This paper describes and defends in detail a novel account of belief, an account inspired by Ryle's dispositional characterization of belief, but emphasizing irreducibly phenomenal and cognitive dispositions as well as behavioral dispositions. Potential externalist and functionalist objections are considered, as well as concerns motivated by the inevitably ceteris paribus nature of the relevant dispositional attributions. It is argued that a dispositional account of belief is particularly well-suited to handle what might be called "in-between" cases of believing—cases in which it is neither quite right to describe a person as having a particular belief nor quite right to describe her as lacking it.     

Externalist justification and the role of seemings

It’s not implausible to think that whenever I have a justified noninferential belief that p, it is caused by a seeming that p. It’s also tempting to think that something contributes to the justification of my belief only if I hold my belief because of that thing. Thus, given that many of our noninferential beliefs are justified and that we hold them because of seemings, one might be inclined to hold a view like Phenomenal Conservatism, according to which seemings play a crucial role—perhaps the only crucial role—in the justification of our noninferential beliefs. But Phenomenal Conservatism seems to conflict, in a number of ways, with externalist accounts of justification. As a result, the attractiveness of the intuitions appealed to in support of views like Phenomenal Conservatism present something of a challenge to externalism. The purpose of this paper is to deal with that challenge by developing and defending an externalist-friendly account of the role of seemings in the formation and justification of our noninferential beliefs—an account that incorporates what is attractive in views like Phenomenal Conservatism. Because this externalist-friendly account is compatible with both externalist accounts of justification and the plausible elements of views like Phenomenal Conservatism, the challenge to externalism inspired by such views is thereby undermined.     

XII—Escaping One's Own Notice Knowing: Meno's Paradox Again

The complex way Meno's paradox is presented in the Meno forces reflection on both the external conditions on inquiry—its objects—and its internal conditions—the state of mind of the person who inquires. The theory of recollection does not fully account for the internal conditions—as Plato makes clear in the critique of Meno's puzzle to be found in the Euthydemus. I conclude that in the Euthydemus Plato is inviting us to reject the externalist account of knowledge urged on Socrates by the sophists in favour of a more richly internalist epistemology.     

Extended Sex: An Account of Sex for a More Just Society

We propose an externalist understanding of sex that builds upon extended and distributed approaches to cognition, and contributes to building a more just, diversity‐sensitive society. Current sex categorization practices according to the female/male dichotomy are not only inaccurate and incoherent (attributing nonreproductive properties to differences in vaguely defined reproductive roles), but they also ground moral and political pressures that harm and oppress people. We argue that a new understanding of sex is due, an understanding that would acknowledge the variability and, most important, the flexibility of sex properties, as well as the moral and political meaning of sex categorization. We propose an externalist account of sex, elaborating on extended and distributed approaches to cognition that capitalize on the natural capacity of organisms to couple with environmental resources. We introduce the notion of extended sex, and argue that properties relevant for sex categorization are neither exclusively internal to the individual skin, nor fixed. Finally, we spell out the potential of extended sex to support an active defense of diversity and an intervention against sex‐based discrimination.     

Greco on Reliabilism and Epistemic Luck

I outline Greco’s response to the Pyrrhonian challenge to epistemic externalist theories of knowledge and offer two points of criticism. I also argue, however, that there is an account of epistemic luck available which can cast some light on the dispute that Greco is concerned with, and which could, in principle at least, be regarded as being in the spirit of the proposal that Greco sets out.     

Internalist and externalist aspects of justification in scientific inquiry

While epistemic justification is a central concern for both contemporary epistemology and philosophy of science, debates in contemporary epistemology about the nature of epistemic justification have not been discussed extensively by philosophers of science. As a step toward a coherent account of scientific justification that is informed by, and sheds light on, justificatory practices in the sciences, this paper examines one of these debates—the internalist–externalist debate—from the perspective of objective accounts of scientific evidence. In particular, we focus on Deborah Mayo’s error-statistical theory of evidence because it is a paradigmatically objective theory of evidence that is strongly informed by methodological practice. We contend that from the standpoint of such an objective theory of evidence, justification in science has both externalist and internalist characteristics. In reaching this conclusion, however, we find that the terms of the contemporary debate between internalists and externalists have to be redefined to be applicable to scientific contexts.     

The Humean problem of induction and Carroll’s Paradox

Hume argued that inductive inferences do not have rational justification. My aim is to reject Hume’s argument. The discussion is partly motivated by an analogy with Carroll’s Paradox, which concerns deductive inferences. A first radically externalist reply to Hume (defended by Dauer and Van Cleve) is that justified inductive inferences do not require the subject to know that nature is uniform, though the uniformity of nature is a necessary condition for having the justification. But then the subject does not have reasons for believing what she believes. I defend a moderate externalist account that seeks to partly accommodate that objection to the radical externalist proposal. It is based on an extension of Peacocke’s theory of concepts: possession conditions for predicative concepts standing for natural properties include (fallible) dispositions to project them to new cases in accordance with inductive inferential patterns.

REFRAINING AND THE EXTERNAL

It is usually taken for granted that the necessary and sufficient conditions for refraining are with respect to mental or behavioral states of agents. Let us call such accounts internalist conceptions of refraining. In this paper, I argue that internalist conditions are insufficient for refraining; and so internalist conceptions of refraining are inadequate. I conclude that a proper account of refraining must contain an externalist condition – i.e., a condition that makes reference to an agent's environment.     

Transparency and the KK Principle

An important question in epistemology is whether the KK principle is true, i.e., whether an agent who knows that p is also thereby in a position to know that she knows that p. We explain how a “transparency” account of self‐knowledge, which maintains that we learn about our attitudes towards a proposition by reflecting not on ourselves but rather on that very proposition, supports an affirmative answer. In particular, we show that such an account allows us to reconcile a version of the KK principle with an “externalist” or “reliabilist” conception of knowledge commonly thought to make that principle particularly problematic.     

Some Worries about Normative and Metaethical Sentimentalism

In this response I raise a number of problems for Michael Slote's normative and metaethical sentimentalism. The first is that his agent–based account of rightness needs be qualified in order to be plausible; any such qualification, however, leaves Slote's normative ethics in tension with his metaethical views. The second is that an agent–based ethics of empathic caring will indeed struggle to capture our common–sense understanding of deontological constraints, and that appeal to the notion of causal immediacy will be of little help here. Finally, it seems to me that Slote's metaethical account will turn out to be much less externalist (and hence, by his own lights, much less plausible) than he suspects.     

Reasons and Rational Motivational Access

Practical Internalism holds that an agent's reasons for acting are entirely determined by his rational desires. This account is thought to be preferable to externalism, on the grounds that internalism alone can guarantee that agents have 'rational motivational access' (RMA) to their reasons. Rachel Cohon has recently argued that (i) internalism fails to ensure this, and (ii) an externalist account, akin to relativism, can guarantee RMA. I suggest that both of these claims are mistaken. I argue that relativism is best understood as an internalist theory, and claim that one version of internalism can therefore guarantee RMA.     

Blind Reasoning

The paper asks under what conditions deductive reasoning transmits justification from its premises to its conclusion. It argues that both standard externalist and standard internalist accounts of this phenomenon fail. The nature of this failure is taken to indicate the way forward: basic forms of deductive reasoning must justify by being instances of 'blind but blameless' reasoning. Finally, the paper explores the suggestion that an inferentialist account of the logical constants can help explain how such reasoning is possible.
