((This is, I don't know, maybe the third time I've argued with Michael about something and then concluded he was right all along.)) — Srap Tasmaner
In our version, the base rate of heads interviews is 1 in 3. Make it 1 in 1000. (That is, 999 awakenings on tails, not 2.) Isn't it obvious that if I'm a subject in such an experiment, I know it's far more likely I'm being asked for my credence because my coin came up tails? If I'm one of 1200 subjects, I know there are 600,000 interviews, only 600 of which were for heads, while 599,400 were for tails. Equally likely that this interview is for heads as for tails? Not by a long shot. — Srap Tasmaner
Let's say that I wanted to bet on a coin toss. I bet £100 that it will be tails. To increase the odds that it's tails, I ask you to put me to sleep, wake me up, put me back to sleep, wake me up, put me back to sleep, wake me up, and so on. Does that make any sense? — Michael
She can't. — L'éléphant
The probability that the coin will land heads and she will be woken on Monday is 1/2.
The probability that the coin will land tails and she will be woken on Monday is 1/2.
The probability that the coin will land tails and she will be woken on Tuesday is 1/2. — Michael
Bet on heads or tails. If tails, you get to repeat the same bet again, on the same toss — hypericin
This version looks a lot clearer to me, and the question at the end looks like a deception. 2 possible worlds, contain 3 possible identities. So other things (ie coins) being equal, I am more likely to be one of two than one of one. So P. (only child) is 1/3 notwithstanding P. (heads) is 1/2, because tails is twice as fruitful as heads. — unenlightened
since he gains no new relevant evidence if he wakes up during the experiment. — Michael
To emphasize this answer, imagine head: they wake her the once, but tails, they do it 100 times before the experiment ends. The coin flip odds are still 50/50, but the odds that on a random waking she sees tails is overwhelming. — noAxioms
That was my whole argument regarding all those "crowning achievement" superlatives early in the thread. I wasn't putting humans down; merely pointing out that better or worse depend entirely on the criteria of comparison. — Vera Mont
Human beings whilst in one regard are capable of performing completely selfless acts of kindness are equally capable of doing the opposite to such extremes as murder and endless wars. — invicta
The upshot of all this is that it is pretty much impossible to set out the structure of the ontological argument in first-order logic. Or if you prefer, that the argument does not make sense.
Hence it is not valid. — Banno
. But in the non-organic realm, what sense does it make to speak of information at all? — Wayfarer
My guess is that it comes down to the ability to discern between small differences. This is also what instruments do for humans and computers, allow for greater discernablity. — Count Timothy von Icarus
Another fun version I have thought about before:Here is a demonstration — Count Timothy von Icarus
If algorithms are just names, a relatively bare bones symbol shuffling algorithm is almost godlike in it's ability to name almost everything. — Count Timothy von Icarus
It is actually incredibly difficult to define "computer" in such a way that just our digital and mechanical computers, or things like brains, are computers, but the Earth's atmosphere or a quasar is not,without appealing to subjective semantic meaning or arbitrary criteria not grounded in the physics of those systems. — Count Timothy von Icarus
The mistake I mean to point out is that we generally take 10÷2 to be the same thing as 5. Even adamant mathematical Platonists seem to be nominalists about computation. An algorithm that specifies a given object, say a number, "is just a name for that number." — Count Timothy von Icarus
If the state of a computer C2 follows from a prior state C1, what do we call the process by which C1 becomes C2? Computation. Abstractly, this is also what we call the process of turning something like 10 ÷ 2 into 5.
What do we call the phenomena where by a physical system in state S1 becomes S2 due to physical interactions defined by the laws of physics and their entailments? Causation. — Count Timothy von Icarus
In many respects, it is impossible to distinguish communication from computation in contemporary theories. I think they are different and that this shows a weakness in the theories. — Count Timothy von Icarus
That only I can imagine the music in my head. It's not 'an appearance' for anyone, not even me.
'Phenomenon:1. a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question. "glaciers are interesting natural phenomena".' — Wayfarer
My eyes do not point inward so I am unable to verify what goes on behind them. — NOS4A2
No. Phenomena are 'what appears' - sensory input. — Wayfarer
Phenomena' is a hugely overused word nowadays, because it's come to mean, basically, 'everything' - which makes it meaningless, as it doesn't differentiate anything. — Wayfarer
The stream of consciousness is just that, a stream of consciousness. — Wayfarer
I don't think of internal mentation as being phenomenal. — Wayfarer
I'm wondering why you speak in terms of "generating" phenomenal experience. — Janus
Well, first, I'm not at all certain what 'generating your own phenomenal experience' means. Do you mean, hallucinating? — Wayfarer
They don’t have the predicament of selfhood. — Wayfarer
I cannot say I see them. — NOS4A2
t’s direct because there is nothing between perceiver and perceived. The transformation and interpretation of “nervous activity” is indistinguishable from the perceiver and the act of perceiving, so is therefor not in between perceiver and perceived. — NOS4A2
A recent thread has me wondering how far the community here differs from the general community of philosophers. It seems, from the noise, that there are more folk hereabouts who reject realism than in the wider philosophical community. — Banno
you claim to doubt the reality of trees. — Isaac
