Suddenly Susan

First of all: I like Susan Blackmore. In fact, I met her once, at the first proper conference I ever attended (the ”Toward a Science of Consciousness” conference in Tuscon 2004 hosted by David ”madman at the helm” Chalmers). She came and sat next to me during the introductory speech and asked me what had just been said. I said I hadn’t payed that much attention, to be honest, but I seemed to remember a name being uttered. We then proceeded to reconstruct the message and ended up having a short, exciting discussion about sensory memory traces. From now on, I remember thinking (having to dig deeper than just in the sensory memory traces, which will all have evaporated by now), this is what life will be like from now on. It hasn’t, quite.

ANYWAY: So I like Susan Blackmore, but today, I’m using her to set an example.

I recently had occasion to read her very short introduction to consciousness in which she take us through the main issues and peccadilloes in and of consciousness research. One of the sections deals with change blindness and she describes one of the funniest experiments ever devised: The experimenter approach a pedestrian (this is at Cornell, for all of you looking to make a cheap point at a talk) and asks for directions. Then two assistants, dressing the part, walks between the experimenter and the pedestrian carrying a door. The experimenter grabs the back end of the door and wanders off, leaving the pedestrian facing one of the assistants instead. And here’s the thing: only 50% of the subjects notice the switch. The other 50% keeps on giving direction to the freshly arrived person, as if nothing has happened.

This is a wonderful illustration of change blindness, and it’s a great conversation piece. You can go ahead and use it to illustrate almost any point you like, but here comes the problem: there is a tendency to overstate the case, especially among philosophers (I’m very much prone to this sort of misuse myself), due to the fact that we usually don’t know, or don’t care much, about statistics. Blackmore ends the section in the following manner:

When people are asked whether they think they would detect such a change they are convinced that they would – but they are wrong.

We have a surprising effect: people don’t notice a change that should be apparent, and as a result you can catch people having faulty assumptions about their own abilities, and no greater fun is to be had anywhere in life. But Blackmore makes a mistake here: People would not be wrong. Only 50% of them would. It’s not even a case of ”odds are, they are wrong”.

I would use this as an example of some other cognitive bias – something to do with our tendency to remember only the exciting bit of a story and then run with it, perhaps – only I’m afraid of committing the same mistake myself.

(Btw: I also considered naming this post ”so Sue me”)

What did you Quine today?

”Does it contain any experimental reasoning, concerning matter of fact and existence?” – David Hume

In last weeks installment of the notorious radio show that I’ve haunted recently, I spoke to the lovely lady on my left on the picture below about the use of empirical methods in moral philosophy. The ”use of empirical methods” of which I speak so fondly is, on my part, constricted to reading what other people has written, complaining about the experiments that haven’t been done yet, and then to speculate on the result I believe those experiments (not yet designed) would yield.

Anyway: I have a general interest in experimental philosophy, but I haven’t signed anything yet, you know what I mean? That is: I don’t think (what the host of the radio show wanted me to say) that ”pure” armchair philosophy is uninteresting. Indeed, I believe that any self-respecting empirical scientist ought to spend at least some time in the metaphorical armchair, or nothing good, not even data, can come out of the process.

When coming across a philosophically interesting subject matter (and, let’s face it, they’re all philosophically interesting, if you just stare at them long enough. Much of our discipline is like saying the word ”spoon” over and over again until it seems to loose its meaning, only to regain it through strenuous  conceptual work) I often find it relevant to ask ”what happens in the brain”? What are we doing with the concept? It is obviously not all that matters, but it seems to matter a little. Especially when we disagree about how to analyze a concept, there might be something we agree on. Notoriously, with regard to morality, we can disagree as much as we like about the analysis of moral concepts, but agree on what to do, and on what to expect from someone who employs a moral concept, no matter what here meta-ethical stance. Then, surely, we agree on something and armchair reasoning just isn’t the method to coax it out.

I try to be careful to emphasize that empirical science is relevant to value-theory, according to my view, given a certain meta-ethical outlook. Given a particular way to treat concepts. If we treat value as a scientific problem, what can be explained. Since there is no consensus on value, we might as well try this method. Whether we should or not is not something we can assess in advance, before we have seen what explanatory powers the theory comes up with.

Treating ”value” as something to find out about, employing all knowledge we can gather about the processes surrounding evaluation etc. is, in effect, to ”Quine” it. It seems people don’t Quine things anymore, or rather: that people don’t acknowledge that this is what they’re doing. To Quine something is not the same as to operationalize it, i.e. to stipulate a function for the concept under investigation, and to say that from now on, I’m studying this. To Quine it is to take into consideration what functions are being performed, which have some claim to be relevant to the role played by the concept, and to ask what would be lost, or gained, if we were to accept one of these functions as capturing the ”essence” of it. It is to ask a lot of round about questions about how the concept is used, what processes influence that use and so on, and to use this as data to be accounted for by an acceptable theory of it.

Stop reading, start writing

My first all too serious philosophical essay was on Heidegger (well, actually, I did a number on the ”positionality” concept in the work of Sartre earlier still, but it would take an insane amount of scholarly obsession for anyone to ever dig that up). The nicest thing said about was that it is ”not as incomprehensible as these things usually are”. The literature I discussed, I found at the University Library, actually going through a number of philosophy journals. I had a computer at the time, which was just barely hooked up to the internet, but didn’t use it for literature searches, just for writing and the occasional email. I spent a lot of time thinking about the subject of my essay, and used a very limited amount of sources.

A year or so later, while working on a different essay, I discovered JSTOR, and for about a month and a half, the printer didn’t get a rest. It suddenly dawned on me that everything interesting had been written about, at length, from almost every perspective, and the goal to find a theoretical position that was not currently occupied, and then to occupy it, suddenly struck me as much more difficult than I’d imagined. I spent the next few years reading more, too much probably, and thinking and writing less.

I used to do all my best thinking during walks and while running (or derogatorily: ”jogging”). Usually in very dull environments, not to distract from the thinking. Then I got an iPod, and started to listen to lectures, podcasts and audiobooks during those walks and runnings. (iTunes university has some great stuff, the podcasts from Nature, and from TED and the RSA are excellent. BBC 4’s ”thinking allowed” and ”in our time” just have me in stitches). And instead of thinking about what I’ve just heard, I tended to listen to another lecture, podcast or audiobook. Similarly with papers, even books. Before I start working on this chapter, I argued, I just need to read this paper, or that book. One wouldn’t like to be caught out ignorant, now, would one? No, one would not.

The all too great availability of other people’s writing and thinking made me quite heavy on the consumer side of science and philosophy, and much less of a producer. It is, of course, a great thing to learn, and to listen, but in order to become a philosopher, it is necessary to start doing it for yourself. To actually not care, for a bit, whether someone has written that same thing before, and been more well read while doing so.

My dissertation took longer than it should have, and I know people who have been, and still are, in that state where they just can’t seem to finish their texts. Partly, I believe, for this reason. They are excellent, well-read consumers and thoughtful, accomplished critics, but seems almost to have forgotten how to actually do philosophy. (The dominance of ”critical” philosophy among published articles is a testament that this tendency is very common indeed). The kind of second-order thinking were you are constantly reflecting on how what you are writing relates to what other people have written tends to stand in the way of confident, genuinely original and interesting work. At some point, you just have to get out of reading mode, and enter writing mode.

One might, but I wont

I consider banning the phrase ”one might argue that…” from all my future writings. Since these writings have a better than average chance of being writings in philosophy, this ban would be the equivalent of Perec’s ban of the letter ‘e’ from that novel you know you ought to have read already.
You see, it’s such a useful phrase, and it rids you of all responsibility for anything that follows. No referee, however anonymonous, is likely to insert the comment ”no, one might not”. Since philosophy consist to such a large extent of stating propopositions to which one does not assent, dispensing with this trope is perhaps masochistic of me, and might well prove near impossible, but I believe it would be an improving exercise.

Philosophical strategy

When philosophical questions are being asked, my go-to answer is usually ” ‘Yes’, with an ‘if’, or ‘No’ with a ‘but’ .”

Do we have free will? Well, yes, if you’re prepared to accept being within a certain range of mental parameters as having free will. No, if you are looking for something somehow else. Then there is no free will, but there is a pretty good substitute, one that quite closely fits with what we expect from free will, and makes it possible to distinguish between free and unfree acts in a way corresponding to our intentions in using that term. And so on for God, virtues, consciousness, value, causation, etc.

As the discerning reader will no doubt have noticed by now, the ”yes” and ”no” answers can be roughly the same: the qualifications push them into roughly the same position. Which is why one should never rely to much on the fact that one philosopher says ”yes” and the other ”no” to a particular question. Nor, of course, should one rely on the fact (if it ever is one) that two philosophers seem to agree. But mostly, one should take to heart the words of Robert Webb, playing that part of a raging host of the radio show ”Big Talk”:

Guest (being asked whether there is a God): Well, there is no yes or no answer.

Webb: What? I can think of two yes or no answers right of the top of my head!
