I wrote out an example playing of the Monty Hall Problem in Independence Friendly Logic as a game of incomplete information and appended it to my post here.
I also left an extended comment on Dependence Logic vs. Independence Friendly Logic about some of the tribulations encountered as a non-academic trying to get my grubby little hands on obscure logic papers.

Posted in Heidegger, metaphysics, ontology, philosophy at 10:05 am by nogre
In Being and Time Heidegger makes a distinction between death and demise: death is the ending of Da-sein, or Being, and demise is physical perishing. I think this is a good distinction and since I break up ontology into 3 sorts of things – commitments, objects & descriptions – I will have three ways to die:
- Fallen: the perishing of all commitments of a living person.
- Demise: the perishing of physical attributes of a living person (traditional death).
- Annihilation: the perishing of all descriptions that a person has made.
Now Heidegger’s use of death was meant to be a fundamental orientation that Da-sein ‘has’ towards its own end (Those are his quotes around has, not mine- see p. 247 of B&T, p. 229 of Stambaugh) and demise was as above. Hence death and demise are somewhat separate because demise is the physical end and death is the way we are oriented to the end of being.
My view is that demise is one kind, a subset, of overall metaphysical death. I am less concerned here with the existential questions about death (though these are important) and more concerned with the ontological relationship between demise and other sorts of perishing. What follows is the insight separating overall metaphysical death from the three particular ways of perishing.
I’m using fallen in a (only somewhat) technical sense to mean the loss of all commitments. If you lose all capability to have commitments, then you have fallen, almost as in ‘fallen off the map.’ “Gone” is similar- you may not be physically dead, but if you are gone (e.g. to some foreign place never to return) you are dead to those with whom you had made commitments. Comatose, but without physical symptoms, is another example. You’re body may still live and for all anyone knows your mind may be as sharp as ever, but you are incapable of keeping commitments and are therefore ‘dead to the world’.
Demise is death as is traditionally defined: when you have met your demise your body is destroyed. Of course there may be some afterlife in which you may keep your commitments (think Ghost, the movie) or your descriptions of the world may continue (Plato will live forever through his writings – I wonder if someone, somewhere is discussing Plato at every instant of every day), but you’re physically dead as a doorknob after your demise.
Annihilation is the destruction of a person’s descriptions of the world. Describing things is perhaps the most basic of human accomplishments – we reward babies (and philosophers) handsomely for accurate descriptions – and if this is taken away from a person, then that person will not have even achieved the simplest of human accomplishments. Annihilating someone is making the world forget that he or she is a person: it is to become nameless. Perhaps the way to think of it is as in Kafka‘s Metamorphosis: Gregor is changed into a vermin/bug that has a working body and (for a while) can fulfill some commitments, but eventually is unable to communicate how his/its world has changed. At this point any future that Gregor had has been annihilated: the thing he became could continue living, but its life would bear no resemblance to what was formerly Gregor. If all evidence of Gregor’s history was erased, even if the thing he turned into still lived, then Gregor would be completely annihilated.
So to completely metaphysically die, you need to be dead (traditional), gone and forgotten.

The question of what philosophy is always made me squirm. People would ask me what I do, I’d tell them, and then they would ask me what it exactly was that I do. But now I have a answer.
A while back I heard a quote attributed to Russell that went roughly:
Philosophy starts out with propositions that everyone would accept as true, and then ends up with propositions that no one would accept as true.
I thought this made philosophers sound like jerks, but there was something to it: we do end up in weird places for some reason. Here’s why:
Writing philosophy is like writing an instruction manual. You have some act or object or situation that you want to explain because it is hard to use or complicated or dangerous for some reason. So you set out to make a manual for the thing, starting from the most obvious and basic features. Now if you don’t know the thing perfectly, in and out, you end up having bad instructions, regardless of where you started. Then when you try to do something, or understand your object, when you follow the instructions you become hopelessly lost. Both your instructions and whatever the instructions were for are completely inscrutable. But if the instructions are good, then you can do things that were impossible for you to do before hand (program you VCR (or DVR), explain why mathematics is incomplete, that sort of thing). Philosophy is an attempt at writing instruction manuals for confusing things.
This answers the ontological questions of
- Whether or not philosophy is true: it is true if it accurately describes the phenomenon it is attempting to explain. However, since many times we are in the position of not knowing the phenomenon in question, philosophy is often of indeterminate truth.
- Why philosophy is inherently obscure: who ever reads the manual? (I do by the way)
- How best to characterize the strange layouts of philosophical treatises, a la manuals: the beginning is packed with warnings about what is wrong and and dangerous, then basic, most common functions are listed and the interesting and difficult features are buried in jargon somewhere towards the end.
- What are thought experiments: Thought experiments are to philosophy as visual aids/examples are to instruction manuals. They are not needed, but when you can connect the instructions to the actual objects you’re working with, everything becomes easier.
I’m sure this is somewhat silly but when someone presses me on what philosophy is, I’m telling them it’s pretty much writing instruction manuals for confusing stuff.

I found my animal of the month, so it’s time to post some links!
Animal of the Month: Tamandua (30s)
The Killing Machine:
- “Partly inspired by Franz Kafka’s ‘In the Penal Colony’ and partly by the American system of capital punishment as well as the current political situation, the piece is an ironic approach to killing and torture machines. A moving megaphone speaker encircles an electric dental chair. The chair is covered in pink fun fur…” [via]
Kaibo Zonshinzu anatomy scrolls (1819):
- I once worked for a pathology department, and my job required that I go to the morgue on a regular basis (multiple times a day). The human body is completely awesome. These pics are a little gruesome, but then again, so are we.
Speaking of being completely awesome:
- Five-year-old inventor comes up with a better broom. (At 5 I invented the bag-o-bags: a bag that contained other bags, so that you would have lots of bags. It was a homework assignment in kindergarten. I recall being pissed because I didn’t think it was fair that at 5 we should be asked to know enough to solve anything. My parents still tease me about it till this day.)
- Discovery Channel’s new ad: I Love the World (1:01) [via]
Some fun from CScout Japan:
