Naturalising Epistemology: Quine vs. Crumley
There are two possible replies that Quine may wish to advance in response to the inferential gap question. He may simply, and stubbornly, maintain that such questions are no longer relevant once we dispense with first philosophy. However, it is not immediately clear that giving up the quest for a justification of science means that all normative questions regarding inferences are therefore irrelevant. Quine's second option would be to provide a normative description of what justifies our theoretical inferences, but from a naturalistic perspective.
Which of these options Quine himself would opt for is not clear since on separate occasions he seems to make statements suggestive of both possible replies. However, in what follows I will take the second line of response (if only because doing so would make for a much more interesting post). To wit, I will argue in favour of a normative, and yet naturalistic, description of our inferences from evidence to theory. The starting point for just such a normative description is alluded to by Quine himself: "Again there is the area [called] evolutionary epistemology [that] shows how some structural traits of perception could have been predicted from survival value."[Quine (1994), 30]
Defenders of traditional epistemology emphasise that epistemology is not only concerned with which belief forming mechanisms are truth-conducive, but also with why they are truth-conducive. Hence, an adequate naturalistic account of knowledge should provide no less. The naturalistic response to this challenge is an evolutionary epistemology that explains justified belief in terms of natural selection. On this view, nature has endowed us with cognitive mechanisms and epistemic practices that are biased towards truth. The underlying assumption here is that natural selection isolates and preserves those belief-forming mechanisms that are truth-conducive. Creatures with belief forming mechanisms that are generally not truth-conducive fair very poorly in the evolutionary struggle and eventually go extinct. If nature has constructed us so that we are biased towards truth, then the best means at arriving at truth is to use the very cognitive mechanisms nature has given us. Thus, evolutionary epistemology's investigation into our use of induction and our reliance on our perceptual mechanisms turns out to be not merely a descriptive but also a normative endeavour. In brief, had our belief forming mechanisms not been generally truth-conducive (as the sceptic fears) we would not even be around to talk about them.
Jack Crumley raises two objections to the above evolutionary account of epistemic justification. Crumley notes that the evolutionary argument depends on the assumption that natural selection favours mechanisms that are generally truth conducive. However, he points out that false beliefs may often have survival value. For instance, erring on the side of caution may often prove be of greater survival value than an even-handed assessment. To wit, the individual that ran away every time the bush rustled because she assumed that there was a lion in the bushes may fair better than her pathetic, yet epistemically more praiseworthy, companion who sticks around to investigate. Secondly, Crumley notes that it is questionable that many of our scientific beliefs contribute to our survival. Thus, he remarks poignantly: "Nature seems, at best, indifferent to whether we truly believe that quarks have flavours."[Crumley (1999), 203]
In my next post on this topic I will respond to Crumley’s objections.

Naturalised Epistemology: Quine vs Stroud (Part 2)
Quine maintains that the meaning of words is determined by their usage within a linguistic community. When we say: "there is a spoon," we are simply referring to a certain set of sensory stimulation’s to which our linguistic community has inter-subjectively applied the label "spoon." Ontological worries regarding the nature of what lies behind sensory stimulation is irrelevant to the relationship between language and these sensory stimulations. In short, what science regards as a "real" spoon is just that inter-subjective set of sensory stimuli:
What then does our overall scientific theory really claim regarding the world? Only that it is somehow so structured as to assure the sequences of stimulations that our theory gives us to expect. More concrete demands are indifferent to our scientific theory itself. (Quine [1981], p. 474).
For a detailed and extended discussion of Quinean naturalised epistemology see Ben Bayer's paper, Varieties of Naturalized Epistemology: Criticism and Alternatives.

Naturalised Epistemology: Quine vs. Stroud (Part 1)
Quine believes that traditional epistemology's attempt to find a justification for knowledge outside of or prior to science has either failed or is moribund. Our only remaining hope of finding a validation for science is within science itself. Hence, Quine's now famous (or is that infamous?) declaration:
"Epistemology, or something like it, simply falls into place as a chapter of psychology and hence of natural science. " (Quine [1994] p. 25).By Quine’s lights, epistemology is like the mariner in Neurath's parable that has to rebuild his ship as he is sailing on it. We can no more attain a pre-theoretical understanding of science than we can get off a ship while already out at sea.
Defenders of the traditional view tend to object to Quine's naturalised epistemology on two grounds: (1) because it is circular and therefore incoherent and (2) because it lacks the normativity central to epistemology. Stroud's "Reply to Quine" draws on both of these objections. Like traditional epistemology, naturalised epistemology seeks to uncover the relationship between observation and theory. This means providing an account of the disparity between the "meagre" sensory input and the "torrential" theoretical output. This difference between meagre input and torrential output suggests that most of our theoretical knowledge is posited rather than given. In normal scientific investigation we are able to compare a subject's output to the actual world and thereby ascertain how accurately it represents the world.
However, Stroud notes that when we attempt to engage in such a scientific analysis reflexively we encounter the following two-horned dilemma. First, if we assume the accuracy of the scientific picture of knowledge, we find ourselves confronted with the conclusion that all our theories are merely posits. This would not be as bad as it sounds if it we were somehow possible to verify whether our theories accurately represent the world or not. However, when we realise that all our means of evaluating our theories are themselves merely theoretical constructions, or so the argument goes, we find ourselves in a vicious circle. The second horn of the dilemma would be to assume that our scientific picture is wrong, in which case we would simply be confirming the sceptic’s worse fears. Either horn of the dilemma appears to present Quine with an unfavourable outcome.
In my next post on this topic I will look at Quine’s reply to Stroud.

The 46th International Philosopher's Carnival
A NARROW CROSS-SECTION OF PHILOSOPHY
FROM ACROSS THE WEB
A Philosophy (Pseudo) Conference
Hosted by the Space of Reasons
Monday, April 23rd, 2007
Welcome to the 46th instalment of the Philosopher's Carnival, which takes the form or a philosophy pseudo-conference, showcasing a narrow cross-section of philosophy on the web. A special thank you goes out to Professor Daniel Dennett for his submission, which raises important questions with regards to what constitutes a worthwhile philosophical research program. In the three "presentations" immediately following the "keynote address" (under the heading of METAPHILOSOPHY), two philosophy students and one non-philosopher share their views on the status and role of philosophical theories. We then turn to the heart and soul of the Carnival which features a number of “presentations” that fall under the heading of Language, Epistemology, Metaphysics and Mind (or LEMMINGS). Finally, we top it all off with a sprinkling of ETHICS and a brief IN DISCUSSION section. Enjoy!

"Selling Out" McDowell
The “sell-out” objection derives most of its force from the fact that the label of “J-internalist” is not one that McDowell ever applies to himself. Moreover, I suspect that McDowell would positively object to the application of such a label to his approach, even if compelling theoretical grounds could be presented for doing so. My suspicion is rooted in what I believe to be one of the chief motivations behind McDowell’s decision to use unconventional philosophical terms when articulating his position. After decades, and in some cases centuries, of use in countless debates, much of the traditional language of epistemology has become hopelessly cathected with a host of conflicting (and often unhelpful) philosophical connotations. Admittedly, theoretical distinctions, such as the internalist/externalist distinction in epistemology, were originally intended to clarify points of disagreement between philosophers. However, according to the “sell-out” objection, the traditional terminology now only serves to conceal and confuse, rather than codify and clarify. Moreover, commitment to a particular approach, the philosophical counterpart to political partisanship, has prevented many philosophers from appreciating the valuable insights contained in alternative views, occasionally even blinding them to ways their own position could be enhanced via a melding with that of others. Thus, McDowell’s reluctance to employ the standard nomenclature of the field seems well motivated.
Breaking ranks from the traditional J-internalist/J-externalist distinction seems to gel with McDowell’s attempt to inject a fresh new perspective on these decades-old debates. Moreover, many would argue that by attempting to apply the “J-internalist” label to his approach I’m making my task much more difficult than it needs to be. Why not simply describe McDowell as best you can and then let the J-internalist/J-externalist chips fall where they may? This, after all, is what he himself seems to do. Moreover, the premature application of a label may, at best, only serve to hide the many subtleties of McDowell’s own position and, at worst, reduce him to a mere recapitulation of someone else’s position or a crude caricature of his own.
While I am sympathetic to these sentiments, I still think there is something to be said for the old distinctions. For one thing, McDowell’s use of unconventional terminology can itself hamper comprehension, as evinced by the audible groans and bewildered protests that issue from the average philosophy student when reading Mind and World for the first time. McDowell is often difficult to follow, to say the least. I maintain that this is due, in no small part, to his use of unconventional terminology and metaphors. At best, this makes it difficult for a reader to immediately appreciate what McDowell is attempting to get across, and at worse, it may prompt the reader to stop reading! By recasting McDowell in the standard language of epistemology I hope to make him accessible to a broader audience. By construing McDowell as a J-internalism I hope to situate him in the philosophical literature. Fulfilling both objectives will not only aid readers in seeing where McDowell stands in relation to others, but would better facilitate the assessment of his relative strengths and weaknesses. Perhaps most important of all, this process will help to clarify McDowell’s unique contribution to the ongoing debates. Rather than forcing him into some preset mould, I believe this will actually foster a better appreciation of just how nuanced a thinker he is.
A final collateral benefit of my attempt to characterise McDowell as a J-internalist is the injection of a fresh perspective into the J-internalist/J-externalist debate. By canvassing the claim that McDowell is a J-internalist I will (eo ipso) be articulating what I take to be a robust and philosophically compelling version of J-internalism. Specifically, I believe McDowell provides J-internalism with a powerful new tool (embodied in his conception of object-dependent singular thought) that relatively few J-internalists recognise as available to them. Thus, if successful, my project would also equip J-internalists with added theoretical artillery in the fight against J-externalism. Given all the aforementioned benefits, can I really be blamed for attempting to “sell out” McDowell for my own epistemological gain.
