Evidence,experience, and externalism

The Sellarsian dilemma is a famous argument that attempts to show that nondoxastic experiential states cannot confer justification on basic beliefs. The usual conclusion of the Sellarsian dilemma is a coherentist epistemology, and the usual response to the dilemma is to find it quite unconvincing. By distinguishing between two importantly different justification relations (evidential and nonevidential), I hope to show that the Sellarsian dilemma, or something like it, does offer a powerful argument against standard nondoxastic foundationalist theories. But this reconceived version of the argument does not support coherentism. Instead, I use it to argue for a strongly externalist epistemology.     

Internalism,externalism, and transcendental idealism

The analyses of the mind–world relation offered by transcendental idealists such as Husserl have often been dismissed with the argument that they remain committed to an outdated form of internalism. The first move in this paper will be to argue that there is a tight link between Husserl’s transcendental idealism and what has been called phenomenological externalism, and that Husserl’s endorsement of the former commits him to a version of the latter. Secondly, it will be shown that key elements in Husserl’s transcendental idealism, including his rejection of representationalism and metaphysical realism, is shared with a number of prominent contemporary defenders of an externalist view on the mind. Ultimately, however, it will be suggested that the very alternative between internalism and externalism—an alternative based on the division between inner and outer—might be inapplicable when it comes to phenomenological conceptions of the mind–world relation.     

Husserl and externalism

It is argued that Husserl was an “externalist” in at least one sense. For it is argued that Husserl held that genuinely perceptual experiences—that is to say, experiences that are of some real object in the world—differ intrinsically, essentially and as a kind from any hallucinatory experiences. There is, therefore, no neutral “content” that such perceptual experiences share with hallucinations, differing from them only over whether some additional non-psychological condition holds or not. In short, it is argued that Husserl was a “disjunctivist”. In addition, it is argued that Husserl held that the individual object of any experience, perceptual or hallucinatory, is essential to and partly constitutive of that experience. The argument focuses on three aspects of Husserl’s thought: his account of intentional objects, his notion of horizon, and his account of reality.     

Evidential externalism

Consider the Evidence Question: When and under what conditions is proposition P evidence for some agent S? Silins (Philos Perspect 19:375?C404, 2005) has recently offered a partial answer to the Evidence Question. In particular, Silins argues for Evidential Internalism (EI), which holds that necessarily, if A and B are internal twins, then A and B have the same evidence. In this paper I consider Silins??s argument, and offer two response on behalf of Evidential Externalism (EE), which is the denial of Evidential Internalism. The first response claims that the allegedly unattractive consequence for EE is not so unattractive. The second response takes the form of a tu quoque, demonstrating that a structurally similar argument can be constructed against EI. The two responses play off one another: objecting to the first puts pressure on one to accept the other. Taken together, the two responses have important ramifications for how we answer the Evidence Question, and how we think about evidence in general.     

Phenomenal character, phenomenal concepts, and externalism

A celebrated problem for representationalist theories of phenomenal character is that, given externalism about content, these theories lead to externalism about phenomenal character. While externalism about content is widely accepted, externalism about phenomenal character strikes many philosophers as wildly implausible. Even if internally identical individuals could have different thoughts, it is said, if one of them has a headache, or a tingly sensation, so must the other. In this paper, I argue that recent work on phenomenal concepts reveals that, contrary to appearances, this standard conjunction of externalism about content and internalism about phenomenal character is ultimately untenable on other models of phenomenal character as well, including even “qualia realism.” This would be significant for a number of reasons. The first is patent: it would undermine a primary objection to representationalism. The fact that representationalism is incompatible with the conjunction would be no serious problem for representationalism if no other plausible model of phenomenal character is compatible with it. The second is that the many philosophers who embrace the conjunction would be forced to abandon one of the two views; externalism would be true either of both content and phenomenal character, or of neither. Likewise, those philosophers who have taken a stance on only one of the two internalism/externalism debates would have to be seen as thereby committed to a particular stance on the other. The third reason stems from the fact that qualia realism typically goes hand in hand with internalism about phenomenal character. To the extent that it does, my argument would reveal that qualia realism is itself in tension with externalism about content. This would perhaps be the most surprising result of all.     

Putnam,realism and truth

There are several distinct components of the realist anti-realist debate. Since each side in the debate has its disadvantages, it is tempting to try to combine realist theses with anti-realist theses in order to obtain a better, more moderate position. Putnam attempts to hold a realist concept of truth, yet he rejects realist metaphysics and realist semantics. He calls this view internal realism. Truth is realist on this picture for it is objective, rather than merely intersubjective, and eternal. Putnam introduces a concept of epistemic idealization — epistemically ideal conditions, or idealized justification — to try to ground the strong objectivity of truth without sliding into metaphysical realism. I argue that the concept of ideal conditions to which Putnam appeals does not cohere with his (anti-realist) commitment to an assertability conditions account of meaning.     

Phenomenological immanence,normativity, and semantic externalism

This paper argues that transcendental phenomenology (here represented by Edmund Husserl) can accommodate the main thesis of semantic externalism, namely, that intentional content is not simply a matter of what is ‘in the head,’ but depends on how the world is. I first introduce the semantic problem as an issue of how linguistic tokens or mental states can have ‘content’—that is, how they can set up conditions of satisfaction or be responsive to norms such that they can succeed or fail at referring. The standard representationalist view—which thinks of the problem in first-person terms—is contrasted with Brandom’s pragmatic inferentialist approach, which adopts a third-person stance. The rest of the paper defends a phenomenological version of the representationalist position (seeking to preserve its first-person stance) but offers a conception of representation that does not identify it with an entity ‘in the head.’ The standard view of Husserl as a Cartesian internalist is undermined by rejecting its fundamental assumption—that Husserl’s concept of the ‘noema’ is a mental entity—and by defending a concept of ‘phenomenological immanence’ that has a normative, rather than a psychological, structure. Finally, it is argued that phenomenological immanence cannot be identified with ‘consciousness’ in Husserl’s sense, though consciousness is a necessary condition for it.     

Reduction,externalism and immanence in Husserl and Heidegger

This paper argues that the Husserl–Heidegger relationship is systematically misunderstood when framed in terms of a distinction between internalism and externalism. Both philosophers, it is argued, employ the phenomenological reduction to immanence as a fundamental methodological instrument. After first outlining the assumptions regarding inner and outer and the individual and the social from which recent epistemological interpretations of phenomenology begin, I turn to the question of Husserl’s internalism. I argue that Husserl can only be understood as an internalist on the assumption that immanence equates with internal. This, however, is not the case as can be seen once the reduction is understood not as setting aside the existence of the world, but rather a reflection on its meaning. Turning to Heidegger, I argue that his commitment to a form of the phenomenological reduction precludes him from being either a semantic or a social externalist. The place of authenticity and the first person perspective in his work derive from his phenomenological commitments, which can be seen in his accounts of discourse and language and of falling (Verfallen). I then go on to briefly outline a more plausible basis for understanding the difference between Husserl’s and Heidegger’s phenomenologies in terms of their respective emphases on logic and on poetics.     

Privileged access,externalism, and ways of believing

By exploiting a concept called ways of believing, I offer a plausible reformulation of the doctrine of privileged access. This reformulation will provide us with a defense of compatibilism, the view that content externalism and privileged access are compatible.     

Twin-earth externalism and concept possession

It is widely believed that Twin-Earth-style thought experiments show that the contents of a person's thoughts fail to supervene on her intrinsic properties. Several recent philosophers have made the further claim that Twin-Earth-style thought experiments produce metaphysically necessary conditions for the possession of certain concepts. I argue that the latter view is false, and produce counterexamples to several proposed conditions. My thesis is of particular interest because it undermines some attempts to show that externalism is incompatible with privileged access.     

Putnam and Constructibility

I discuss and try to evaluate the argument about constructible sets made by Putnam in ‘ ”Models and Reality”, and some of the counterarguments directed against it in the literature. I shall conclude that Putnam’s argument, while correct in substance, nevertheless has no direct bearing on the philosophical question of unintended models of set theory.
