Big monkey, logic book 
Rob Helpy-Chalk runs down the options for open access logic books, including forall x. He concludes, "Heck, the Magnus book looks like just the item. That was quick."

Meme: Passion Quilt (and merch) 
Janet tagged me in another meme.*
THE RULES:
Post a picture or make/take/create your own that captures what YOU are most passionate for students to learn about.

Give your picture a short title.

Title your blog post "Meme: Passion Quilt."

Link back to this blog entry.

Include links to 5 (or more) educators.
I ruminated on this for a while, but all the cleverness has been squeezed out of me by interminable grading. So I drew this:


ARE YOU SURE IT'S A BARN?
(and not a cleverly disguised mule?)



This, of course, is one of the suggested t-shirts from my epistemology class. The rationale for including it in the passion quilt is this:

Philosophy cannot be an entirely abstract discipline. Its principles must apply to some instances, if it is to teach us anything at all. At the same time, philosophical examples can get out of hand. Carried too far, the obsession with examples is a round about way of being inapplicably abstract. As JL Austin once wrote, "over-simplification, schematization, and constant obsessive repetition of the same small range of jejune 'examples' are... far too common to be dismissed as an occasional weakness of philosophers."

I don't think that this is really what I am most passionate about students learning, but it is one lesson that I hope they do learn.

All well and good, but the clever reader will suspect that the drawing is just an excuse to make t-shirts with the clever motto on them. Indeed, I've made a Mule Barn Country t-shirt at Cafe Press; also a polo and a long-sleeved version.

Similarly, I've made the 'Evil Demons' shirt available in white and colour.


* Janet was flexible with the rules and so I will be, too. I won't tag anybody. As chain letters always say, this will probably have dire consequences.

Reid rides again 
My Reid paper has now appeared at Philosopher's Imprint.

It's a publication, which is always a good thing, but I'm especially happy with this one. I pointed to an on-line draft of this paper in my first ever blog post. As I've mentioned before, I have a high regard for the journal.

Brief debriefing 
Yesterday was the last day of class, and so it was time for the usual debriefing. I asked slightly different questions in 17th&18th c. Philosophy than last year, so I can't compare numbers directly. Considering favorite and lease favorite material with respect to philosophical content, the results were these:

yay boo
Descartes 4 5
Locke 5 2
Berkeley 3 10
Hume 7 3
Kant 4 1

Even moreso than last year, even students who find Berkeley engaging and interesting tend to be boo about his philosophy. I am surprised by the dearth of Kant haters, but they appear in a moment.

We also ended up discussing philosophical style, and so I had them indicate which text they found the most enjoyable (least unpleasant) to read and which they found most unpleasant (least enjoyable). Most enjoyable is a tossup between the texts not written by Kant, least enjoyable is a transcendental landslide:

yay boo
Descartes' Meditations 7 -
Locke's Essay (selections) 4 -
Berkeley's Principles 5 1
Hume's Enquiry 6 1
Kant's Critique (abridged) - 23



In my Theory of Knowledge class, I ended with a lightweight question: If you had to summarize the course on a t-shirt, what would it say? Answers tended toward what would make a funny shirt, rather than toward what would convey wisdom. For example:

"I've always had a soft spot in my heart for evil demons."

"ARE YOU SURE IT'S A BARN? (and not a cleverly disguised mule?)"

"You won't know what knowledge is, but you'll know what it's not."

"Knowledge: It's not just for brains-in-vats anymore."

In a similar vein, some students volunteered mottoes for bumper stickers:

"In fake barn country, beliefs in the vehicle are not justified."

"My other car is Nogot's Ford."

Now the only thing between me and a summerful of research is reams of grading.

What I believe about easy knowledge 
I've been thinking about this since the conference a couple of weeks ago.

The problem of easy knowledge is alleged to put the kibosh on reliabilism.* Consider, for example, a situation in which I make a series of perceptual judgments. There are many piles of cardboard tokens on the table and I count the number in each. For the first pile, I form a belief B1 about the number of tokens in it.I can reason
1. B1. (That is, B1 is true.)
2. I believe B1.
3. Therefore, I formed a true belief here.
4. Repeating this process for each pile: I formed a true belief in every case.
5. So the process at work in these instances of chit-counting is reliable.
6. Having a belief formed by a reliable process is sufficient for knowledge. (Reliabilism.)
7. Therefore, I know each of the beliefs.

There is no problem with saying that line 7 is true, because we are setting aside sceptical worries here. Nevertheless, there is something wrong with thinking that I can learn line 7 in this way. I extrapolate knowledge about my knowing from mere belief by a kind of legerdemain.

An epistemic rabbit from a doxastic hat!

Second-order knowledge is not really so easy, so something has gone wrong. If premise 6 is where the absurdum comes in, then this is a reductio of reliabilism.

There are several ways to respond:

First, one might problematize the step from the collection of instances to the claim that they are formed by reliable process (4-5). In his conference paper, Colin Caret argues that this inductive move doesn't come for free. It requires a further premise that all of these instances of pile counting are the result of the same process. That premise, he argues, requires some heavy hitting cognitive science. The easy knowledge is not so easy after all.

Second, one might insist that similar problems arise for non-reliabilist epistemologies. As such, it is everybody's problem and not a reductio of reliabilism. Hilary Kornblith suggested this approach after Colin's talk. It has the same bitter taste that accompanies any tu quoque reply.

Third, one might deny that I am entitled to intermediate conclusion 3. This seems awkward, because 3 is a deductive consequence of 1 and 2. Certainly the inference is unobjectionable in the third-person:
A1. P is true.
A2. Colin believes P.
A3. Therefore, Colin believes something true.

Consider, however, what I need to do in order to assess the soundness of this alternate argument. In order to know A2, I need to learn Colin's doxastic state. In order to know A1, I need to learn about whatever part of the world P is about. This is not trivial, at least not as trivial the easy argument is supposed to be. It won't be a reductio if we change the first-person 'I' to the third-person 'Colin'.

When I ask myself whether Colin believes P, I observe him and infer his doxastic state. (Perhaps I just ask him and accept his answer.) When I ask myself whether I believe P, however, I do not simply introspect and determine my preexisting doxastic state. As Gareth Evans and Richard Moran have noted, my determining whether 'I believe that P' is true typically just becomes my determining whether 'P' is true. Determining whether I believe P requires determining whether P, and I mobilize whatever cognitive resources are relevant to it.

In the argument, I am supposed to learn about my own doxastic state by introspection. My introspection just notices that I've formed a belief in B1 by whatever cognitive process is at work. This is the very same state of affairs recorded in premise 1, when I work through the argument for myself. I am tempted to say that 1 and 2 are not even distinct premises here.**

In any case, I don't see how I can accept premise 1 and premise 2 in the way the easy knowledge argument requires. They only make sense as distinct claims if we treat 2 as a third-person belief ascription, but then it no longer comes along for free. So the problem is not with reliabilism at all.


* Specifically, this is the bootstrapping version of the problem.

** Moran argues that 2 as distinct from 1 is coherent, but that rational agents almost never pose 2 in that way. (He calls it the 'theoretical question.') Ron (in conversation) suggested some cases where one might actually pose it. Perhaps I just need for this context to make it impermissible to pose 2 in its distinct, theoretical sense.***

*** I am treating it here as if it's a semantic point. A parallel point might be made if it's a pragmatic difference. (I just footnoted a footnote. I think that is a blogging first for me.)
