The Ministry of Enlightenment for this secessionist republic of one is proud to bring you the 24th installment of the Philosophers’ Carnival in the pages of the Rad Geek People’s Daily. The Philosophers’ Carnival has two primary purposes: (1) To provide lesser-known philosophy bloggers with the opportunity to gain some exposure and attract a wider audience, and (2) to showcase the best that a wide range of philosophy blogs have to offer, in one convenient location, for the benefit of philosophically-inclined readers. Some of the past carnivals have had a unifying theme; others have chosen to group related posts together by subject-heading. We here prefer to link each post in a chain by means of thin justifications for the transition, tenuous topical connections, and frequent red herrings. If you’re the type who likes to avoid that sort of thing (you probably hate candy and laughing babies, too), here’s the precis of what’s in the Carnival this time around:

Fun challenge for the reader: try to guess what each post is about, and how I linked each one to the preceding post, before you scroll down and read the abstracts for yourself.
Ready? On, then, with the show:
Philosophers’ Carnival #24
We begin with post that’s been sitting in the queue for a little while: Henry Sidgwick @ Mind (April 1895): The Philosophy of Common Sense, recently brought to us courtesy of the Fair Use Repository. Sidgwick wants the Glasgow Philosophical Society (and, I suppose, us also) to consider how philosophy may be related to common sense, and how we should best understand philosophers such as Thomas Reid, who methodically and emphatically make appeals to the deliverances of common sense in order to do philosophical work. Far from being intellectual laziness in the name of unreflective gut feelings, Sidgwick notes how Reid
refers to Hume’s account of the manner in which, after solitary reflection has environed him with the clouds and darkness of doubt, the genial influence of
dinner, backgammon, and social talkdispels these doubts and restores his belief in the world without and the self within: and Reid takes his stand with those who are
so weak as to imagine that they ought to have the same belief in solitude and in company.His essential demand, therefore, on the philosopher, is not primarily that he should make his beliefs consistent with those of the vulgar, but that he should make them consistent with his own; and the legitimacy of the demand becomes, I think, more apparent, when we regard it as made in the name of Philosophy rather than in the name of Common Sense.
Following on the theme of philosophy and common sense, Jason Stanley @ Leiter Reports (2005-12-03):
HumanistPhilosophy offers a metaphilosophical guest post.
Much of my blogging,he writes,
has been devoted to trying to figure out which distinctions between kinds of philosophical approaches are merely sociological (e.g. reflections of the personal connections and academic credentials of particular philosophers) and which are genuinely substantive. I do think there are rather fundamental distinctions between kinds of philosophers, but (as I’ve been arguing this week) I don’t think they correspond to any kind ofHe thinks that his finger has been moved somewhat closer to the mark, though, by Michael Strevens’ suggestion that the division is centrally concerned with the relationship that the philosopher sees between philosophy and our ordinary, common-sense self-understanding.
division between departmentsor
nexusesthat clearly divide two or three kinds of departments (such nexuses exist, but they are considerably more sociological in character). Nevertheless, I think that Brian Leiter has been on to something by his division of
humanistphilosophy. I just don’t think that this division explains anything about the sociology of department relations. I just haven’t been able to put my finger on what it is.
Fodor,we are told,
is a humanist insofar as his work on the mind is an attempt to vindicate our self-understanding, our human picture of the mind, but
Stich, by contrast, uses the tools of philosophy to undermine our conception of ourselves, to alienate us from our own minds.Stanley goes on to consider some more typical points of contrast (such as the use of technical apparatus in logic or the appeal to the history of philosophy) that simply cut across the humanistic-scientific divide, and considers the points at which this division connects with Strawson’s division between descriptive and revisionary metaphysicians.
Reflections on our ordinary self-understanding, and of alienation from or comfort with that, easily bring us to questions about satisfaction, happiness, and our ordinary understanding of how happy or how satisfied we happen to be (or fail to be). Will Wilkinson @ Happiness and Public Policy (2005-12-30): Is the Flat Trend in Self-reported Happiness a Problem? looks at that, and specifically at studies of
happinessbased on self-reports. Wilkinson challenges a couple of presumptions that seem to be universal in the reports on, and analysis of, this kind of
happiness study:(1) presuming that a flat trend in self-reports of happiness reliably indicates a flat trend in how happy people in fact are, and (2) presuming that a flat trend in how happy people in fact are would constitute some sort of deep problem that demands policy solutions.
we are getting no happierover
we have been, and remain, extremely successful at creating happiness?The main reason why, I take it, is that it’s impossible to use the happiness data to drum up demand for one’s favorite unpopular policies without framing it in a way that makes it look like there’s some kind of problem that needs to be fixed. If you say that data show that we’re just as happy as our grandparents in America’s nuclear family, bowling together, Leave it to Beaver golden age, we’ll never socialize medicine! Anyway, the point is: at the very least, you need to at least try to eliminate the most plausible competing interpretations of the data before you move on to try to use happiness data to mount your favorite policy hobby horse. No. At the very least, you need to acknowledge that there are alternative interpretations. Until they do that, people trying to sell policy on the basis of happiness research don’t deserve to be taken very seriously.
Speaking of happiness, one of the many things — perhaps one of the most important things — that we’re inclined to connect — in some sense or another — with happiness — in some sense or another — is friendship — in some sense or another. But all three of those
in some sense or anothersare tricky philosophical terrain. Roderick Long @ Austro-Athenian Empire (2006-01-06) recently posted an online copy of his essay from a roundtable on friendship, The Value in Friendship, which sets itself to learning how to ask the questions we need to ask about happiness, friendship, and the connection between them.
The purpose of this essay is to ask a question. The question is:As we get closer to the question, we see that there’s quite a bit of explaining that we need to do about what you value inside a friendship once you’ve got it, and what you value outside friendship that leads you to become friends in the first place, and the relation of both of these questions to happiness, to pleasure, and to satisfaction. Along the way, we also see how friendship (in both of the separate questions we’ve just posed) exposes thorny problems for two of the perennial candidates for theoretical understandings of how we should value people: strictly partial concern for yourself (represented by egoism) and strictly impartial universality (represented by utilitarianism, among others).
What is it that we value in friendship?The purpose of this essay is not to answer the question. That’s a more daunting task than I intend to tackle here. Rather, my purpose is simply to ask the question. You may think I’ve already asked the question; so my essay has achieved its purpose and I should stop right now. After all, didn’t I just say that my question was: what do we value in friendship? But I haven’t really succeeded in asking that question yet, because I haven’t yet clarified what question I am asking. That is, I haven’t yet distinguished the question I want to ask from other questions that are easily confused with it. So we’re not yet at the point of being able to ask my question. We need to wander about in the wilderness a little bit—though hopefully not for forty years—before we can get to the promised land of my question.
One of the reasons you might want to know better what it is that we value, in becoming friends and in being friends — or at least to know better how to start asking those questions — is to get a better grasp on the limits of friendship, on what it can (or should) survive, and when it can (or should) end. To take a very public example, Jerry Monaco (2005-12-18): The Break Between Sartre and Camus: Gossip, Invective, and the Meaning of History nicely takes us through the causes, the effects, and the historical and cultural context of the bitter end Albert Camus and Jean-Paul Sartre’s friendship (as it proceeded from Francois Jensen’s fusillade-review on Camus’s The Rebel in Sartre’s journal Les Temps Moderns). Aside from the (very real, and very damaging) effects of an overheated intellectual culture of invenctive and literary celebrity in post-war Paris, Monaco also draws out some underlying differences of deep moral and philosophical principles, which were expressed in the feud and which ultimately made friendly engagement not only difficult but intolerable for Sartre and Camus:
If one remembers that, at this time (1952), France was actively trying to recover its empire in Indochina and Africa, and that Sartre was actively opposing French colonialism, whereas Camus believed that the anti-colonialists had noMonaco argues that there are important senses in which they were both right and both confused; what he suggests is most important is the way in which the end of their friendship and the limitations of each’s thought came from an inability to work out a common understanding of what questions to ask, how to ask them, and thus what the
moral legitimacy, then one can get a sense of what the feud was
reallyabout from Sartre’s point of view. If one remembers that Sartre was trying to
existentializeMarxism and therefore not offering very acute criticism of the
political actsof the Stalinists, then one can get a sense of what the feud was
reallyabout from Camus’ point of view. For both writers the basic principle was
howto oppose oppression. For Camus
collective resistanceto oppression only leads to more oppression. For Sartre Camus’
quietismcould only lead to the triumph of the oppressors. Camus believed that Sartre had become an ideologue giving cover to Stalinist domination, while he, Camus, was the advocate of individual human dignity. Sartre believed, that Camus was an apologist for French Imperialism, while he, Sartre was simply choosing to be

The question of who was
correctin this argument is not the correct question. The question is how can we come to an historical understanding of the moral issues presented by Camus and how can we come to a moral understanding of the historical issues presented by Sartre. In many ways, in 1952, each represented the missing center in each other’s thought.
These considerations on friendship, and how clash of deep philosophical and moral principle shattered the friendship of Sartre and Camus, brings us to the question of friendship, toleration, and the limits of each. We normally think that tolerance, especially amongst your friends and family, is a virtue—but also a virtue with limits, a virtue that must give way to confrontations with the intolerable. But how do we conceive of the virtue, and where do the limits come from? Aspazia @ Mad Melancholic Feminsta (2005-12-29): On Tolerance: Just Be Polite and Pass the Yams asks what we should make of tolerance:
A few years ago I challenged my students to take tolerance seriously as a concept. I was witnessing wacky folks use this concept to push their questionable hypotheses, practices, and policies. In particular, I was concerned with the religious right’s determination to infiltrate school boards in order to bully well-meaning folks to beShe investigates two different (even antagonistic) notions of tolerance — tolerance as respect and tolerance as politeness — and the role that appeals to tolerance played in her students’ linguistic practice:

For them tolerance meant that you sort ofThus, she wonders whether tolerance can be rehabilitated as a virtue, or whether
put upwith someone you didn’t like, you know, like your annoying great-Aunt who spouts utter nonsense and lives with 8 cats. My students taught me that most people understand tolerance to mean being polite. Perhaps, it’s a WASPy sort of relic. Don’t ruffle feathers, just smile and pass the yams.
We might be better served by a more robust notion than tolerance.
Of course, one of the original cases for which the question of tolerance arose was religious toleration within civil society. The Cynic Librarian (2005-12-15): Britian as New Islam Laboratory? takes issue with those
would say that a moderate, modern Islam is a contradiction in terms,but (with the help of an essay by Tahir Abbas) wants to take a hard look at the genuinely hard problems about the relationship between Islam, Muslims and modernity: not only how far modernity can tolerate Islam, but how far Islam can tolerate modernity.
[T]he larger question, as I see it, [is the question] of what will happen to Islam as secularism and consumerist values seep slowly into the bones of the young. They will face the question of either rejecting the faith outright, watering the faith down to a shell of its former self, or reacting in fundamentalist rage at the surrounding profane society.Does the solution lie in politics? In civil society? In religion? Or in rethinking all of the above?
And from the debate over religious faith and modernity, where else could you go but a discussion of natural science and the concept of a miracle? Francois Tremblay @ Goosing the Antithesis (2005-11-14): Miracles and materialism reviews the Humean epistemological argument against believing in miracles, and then offers a metaphysical argument that the concept of a miracle (as something that contravenes materialistic natural causation) entails the non-existence of God, by virtue of the (materialistic) form of causal explanation that theists need to identify with natural law in order to make sense of the concept of a miracle:
For a miracle to be a miracle, it must be miraculous, that is to say, it must break natural law. And natural law is the result of materialist causation. So the definition of a miracle itself implies that materialism is true ! For it includes both material causation and itsAn embarassing predicament for the theist, if the argument works.
breakfor a specific event. If there is no material causation, then the concept of miracle is meaningless.
Meanwhile, Kenny Pearce (2005-12-22): Let’s Make Creation Science Not Suck offers a Christian attack on the notion of contra-causal miracles, drawing on arguments from Leibniz. He argues that both naturalist opposition to Christianity, and Christian opposition to natural science, are the result of bad theology and bad science; specifically the mistaken belief in a conflict between the scientific understanding of the world and the reality of miracles — as embodied in the very concept of a miracle as a contravention of natural law. Thus, with Leibniz, Pearce says,
I continue to hold that it would essentially amount to God making a mistake if he had to break his own physical laws in order to bring about his will miraculously. Rather, the perfect wisdom and infinite power of God should lead us to conclude that he made a world in which his laws hold always, and that he is able to bring about his will, even in those things we consider miraculous, without breaking physical laws. If I am right about this, then the enterprise of science seen as the attempt to explain everything in the physical world by efficient causes is theologically legitimate.If
Creation Scienceis not to suck, Pearce suggests, it has to give up the idea that it is confronting natural science with a conflicting (miraculous, revealed) explanation of worldly happenings, and instead return to a Leibnizian program of
theology of nature, in which
theists should make use of final causes in their investigations of natureas a means both to scientific discovery and a better understanding of the ways of God. As an example of how this might work, he points out Leibniz’s example of Snell (whose development of optics, Leibniz claims, depended in part on reasoning from God’s perfection), and also asks us to lee[ am eye on
the aesthetic criteria which mathematicians and physicists increasingly make heuristic use of.
But even if the use of God-inspired heuristic principles produces good results, does having once made use of them require us to continue to take them seriously in order to avail ourselves of the results? Along these lines, Clayton @ Think Tonk (2005-12-31): Evolutionary naturalism undefeated? closed out the year by trying to kick the ladder out from under Plantinga’s argument that evolutionary naturalism (E&N) is epistemologically self-defeating; his response is to argue that even if Plantinga’s argument initially works, it gives us no lasting reason to insist on the hypothesis of an Intelligent Designer. Once we’ve reasonably determined that having reliable cognitive capacities (R) supervenes on a particular constitution (C), even if we have to begin with the hypothesis that God created us so that R is true in order to reasonably make that discovery, Clayton argues that, since Plantinga
is not claiming that God makes it the case that the conditional probability of R on C is high, [but] that by accepting T, we learn that R on C is high, then
if we take him at his word in this claim, the conditional probability of R on C is high enough that we can rationally believe R and can rationally believe that R would be true so long as C is true even if E&N were true, too. But if that’s so, it seems we’ve climbed the ladder and are ready to kick it away. And once we’ve done that, we have no reason to think E&N cannot be accepted.Thus, it may be Plantinga’s justification for theism, and not naturalism, that contains the seeds of its own destruction.
Questions about self-defeating hypotheses, intelligent design and the chances that our world would turn out to be the way it is tangentially inspired Chris @ The Uncredible Hallq (2006-01-02) in A Gambler’s Epistemology, where he considers how far a common response to radical skepticism can be rationally sustained.
A common response to radically skeptical thesis (we can’t know if the sun will rise tomorrow, we can’t know whether we’re living in a Matrix-type world or not) is,But, Chris worries, discarding a hypothesis just because it defeats our epistemological hopes seems shaky; it seems to rely on a postulate to the effect that a world without undiscoverable secrets are more likely to be the world we live in than a world with undiscoverable secrets. And if ID theorists don’t have a right to the apriori determinations of probabilities that they often lay claim to in order to justify their arguments against naturalism in general or evolution specifically, then it seems that anti-skeptics don’t have a right to apriori determinations of probabilities in order to defeat skepticism, either.
well, true, but if the sun won’t rise tomorrow, there’s nothing we can do about it.[I’ve] toyed with a broader form of that idea in a previous post on proof. The broad form is
reject possibilities that cannot be evaluated on the evidence, because if they’re true, there’s nothing we can do about it.For example, if there’s some evidence that we do in fact live in a Matrix-world, we could consider the evidence, but we must reject the idea of a Matrix-world that is impossible to identify as such.
Meanwhile, Richard Chappell @ Philosophy, et cetera (2006-01-06): Transcendental Arguments also considers a form of argument from self-defeat, which he calls
Transcendental Arguments, or
Practical Arguments.(It’s unclear to me whether what Richard has in mind is identical with what Kant famously had in mind when he talked about
transcendental arguments.I expect that it has a lot to do with how you spell out the details.)
What I have in mind,he says,
are those assumptions that we must make as a precondition to any sort of intellectual progress. Or, more generally, those things that we ought to believe because we’ve got nothing to lose by doing so. If they’re false then we’re screwed anyway, so we might as well just believe them and hope for the best …. it’s not as if the arguments do anything to establish the truth of the belief in question; they merely show that we might as well believe it.As an example, he offers arguments for believing in free will and the laws of thought based on the principle that if we can choose to believe anything, or if we can rationally demonstrate any belief, then there must be free will and the laws of logic must apply; and if we can’t, then we didn’t make the wrong choice or else we couldn’t gain a justified belief by believing otherwise (since without the laws of logic there is no rational justification at all). Wagering against them is in some important respect self-defeating (since at best it is no better justified than the competing view), so go ahead and place your bets on free will and logic. Richard closes by asking whether this sort of reasoning is in fact any good, and where else it might be applied if it is. This may be a good reply to Hallq’s worries as to where the evidential force of the
nothing to losecomes from when we dismiss undiscoverable secrets (including radical skepticism) from consideration in looking for good explanations of the world; or it may be subject to exactly the objection to that strategy that Hallq raises. Beware: dialogue may be close at hand!
On the topic of good explanations and undiscoverable secrets, Doctor Logic (2006-01-03): More on explanation offers an attempt to work out just what explanation is, and how a good explanation might or might not relate to explainers that are beyond our ken. The good Doctor suggests that the essential feature of an explanation is a predictive function from causes to effects; he suggests that as long as the predictive function is there, the cause could be either visible or secret, but that purported
explanationswhere the purported cause
is such that it leaves no evidential trace,then what we have is not even a bad explanation or an unscientific one, but simply fails to give an explanation of the phenomena at all. If this account of explanation works, it would mean (among other things) that radically skeptical
hypothesesfail to even offer an alternative explanation of our experiences for us to consider.
Thinking about explanation and the limits thereof naturally brings us to the explanation of thinking, and whether those limits can encompass explanations of conscious mental states by means of natural facts. Ellis Seagh @ Consciousness and Culture (2005-12-21): Light and darkness: consciousness and reflex takes issue with Chalmers’ claim of an inevitable
explanatory gapbetween natural (neurochemical) properties and first-person phenomenal properties.
Specifically, Seagh argues, there seem to be obvious differences between typical examples of unconscious mental functions and typical examples of conscious mental functions, and these differences seem to have a natural explanation: conscious experience. But if phenomenal properties play an explanatory role in natural processes, then Chalmer’s claim of a systematic explanatory gap seems to be premature.
Why is the performance of these functions [that areChalmers asks, in the paper that re-introduced the idea of an
in the vicinity of experience] accompanied by experience?
explanatory gapin all attempts to construct an explanation of consciousness. A little later he puts the same question a bit differently:

zombiethought-experiment to argue against a materialist, and in favor of a dualist, approach to comprehending consciousness as a phenomenon. My argument here, however, is that he gave up too quickly.
From one sort of explanatory gap to another: we’ve looked at the purported gap between the natural and the phenomenal; now let’s look at the purported gap between the natural and the normative. It’s common enough to note cases in which an is fails to completely account for an ought; but David Shoemaker @ PEA Soup (2006-01-02): Carnivores on the Run looks at a case in which an ought fails to determine an is, even though it seems that it should —
I’m a carnivore. Yes, I said it. But I’m finding there to be less and less of a rational justification for this position. (That’s probably an inaccurate way of putting it, for it may be that there just is no rational justification for it, and never has been, in which case the scalar dimension of this comment refers literally to the degree of scales that have fallen from my eyes, rather than to the degree of justification itself.) Nevertheless, I also find myself utterly unmotivated to change my ways. And I know I’m not alone here (I know for a fact that there’s at least one other PEA brain, for example, who is in the same situation). So what’s going on?David goes on to briefly outline the standard marginal case arguments for ethical vegetarianism, and then asks: if you find the arguments for ethical vegetarianism convincing, but keep on eating meat anyway, what sort of ethical and cognitive position might you be in? Broadly speaking, what do we say about everyday habits that go against the ethical principles we find intellectually convincing?
Marginal cases and meat-eating brings us to a couple of guest posts I recently contributed. There’s Rad Geek @ Philosophy, et cetera (2005-12-05): Freak intelligence, marginal cases, and the argument for ethical vegetarianism and Rad Geek @ Philosophy, et cetera (2005-12-07): The ends in the world as we know it. The first concerns the argument itself:
I think that we have some pretty substantial ethical obligations toward non-human animals (hereafter: “animals”; sorry, taxonomic correctness). In fact, I think those obligations are substantial enough that we’re ethically bound, among other things, to stop slaughtering cattle, pigs, chickens, etc. for food. I can’t say, though, that I’m particularly thrilled with the state of the philosophical debate, and in particular I’m not particularly thrilled with a lot of the arguments that try to defend something like my conclusion. Part of the problem is a problem that’s general in a lot of applied ethics: the desire to make arguments that seem to be compatible with a lot of very different philosophical or meta-ethical views tends to end up with arguments that are actually compatible with only a very narrow view of what the world contains. (That’s because, by design, anything that looks too philosophically murky or controversial is pared away in order to make the argument’s appeal broad enough. But what if the world really does have philosophically murky or controversial features?) As a chief example, take the argument over so-calledI go over marginal case arguments more closely and try to set out a response making use of Michael Thompson’s work in The Representation of Life on
marginal casesand the ethical significance of belonging to a particular species.
aristotelian categoricals(which are explored at greater length in the second guest post) and the natural properties of living creatures; the upshot is that carnivores might be able to defend themselves by an appeal to the natural capacity for rationality (of some kind or other) that humans have. (I don’t think the defense is convincing, but showing why requires detail work on the relation between moral standing and rationality, rather than a schematic marginal cases argument.)
The question of marginal cases and
natural capacitiesbrings us to Patrick @ Tiberius and Gaius Speaking… (2006-01-06): Capability and Potentiality:
The philosophical debates over abortion and the rights of animals are beset by a common question: what characteristic(s), if any, can be listed and described to correctly pick out members of our moral community? In the abortion debates, the worry is that all the arguments that demonstrate the permissibility of abortion also establish the permissibility of infanticide. And since infanticide is pretty roundly condemned, that’s a problem. Similarly, many have argued that no account of what constitutes humanity will include marginal cases like infants or the cognitively disabled but exclude more sophisticated animals.Patrick suggests that a distinction among different kinds of
natural capacity— specifically, between potentiality and capability, and then between physical capability and what he calls actual capability, may make some progress toward a solution. If the moral standing of human beings is connected with rationality (as is often suggested in both abortion and animal rights debates), then you’ll get different rules depending on whether you are citing the actual capability for minimal rationality (which would allow for killing fetuses, infants, adults with severe cognitive disabilities, and beasts), bare potentiality for minimal rationality (which would prohibit killing not only fetuses and infants, but perhaps even sperm, eggs, or skin cells under the right conditions), or physical capability for minimal rationality (which might—pending further results from developmental physiology, anyway—allow for killing beasts and aborting early pregnancies, but draw the line somewhere fairly late in pregnancy). Patrick favors physical capability for minimal rationality as drawing the line in something like the intuitive place.
As always, you really should read the whole thing.
The 25th installment will appear at The Uncredible Hallq, sometime in late January. Keep your eyes peeled!
