Gettier cites the Theaetetus, Chisholm, and Ayer, for starters. Obviously the stars of Chisholm and Ayer have dimmed somewhat since then. Besides expl...

Well, it was over fifty years ago. A simpler time. Plus, it's a theory with some pedigree. Plus, "justification" is a pretty flexible word. Informally...

All Gettier says is that the Smith has "strong evidence" for the proposition that Jones owns a Ford. Do you recommend holding out for justification th...
September 22, 2017 at 23:42
Sure. Do you draw some conclusion from this? For instance, do you have an answer to the question you posed:
September 22, 2017 at 23:40
If you just mean the usual way, then we choose from among things that already exist, but things we make don't exist until we make them. If this what y...

@"apokrisis" Have you looked at this challenge to Landauer? Odd coming right on the heels of this.
September 22, 2017 at 22:45
Just "because"?

Quick note on the linguistics here: (1) Mary gave me £10 because I won; and (2) Mary didn't give me £10 because I won usually both presuppose that Mar...

? I mean something as simple as this: I think there are 4 beers in the fridge because I think there are 3 Guinness and 1 Bud Light. Sadly, there's 1 G...

Together with abduction, yes. This is how we reason about matters of fact, sure. Which he needn't; he only needs his belief to be justified. As Gettie...
September 21, 2017 at 21:45
No. But for many philosophers the intuition here is that the justified true beliefs in Gettier cases are not knowledge, so it's a problem for such acc...

(Since @"Michael" has made a gambling argument, here's the argument I've put off making on the grounds that it's a lot of trouble for little chance of...

The trouble comes this way: If you have good reason to believe that p, then you have good reason to believe that p v q, and if p v q is true you have ...

I predict great success for the hypothesis that it was either coffee or something else. But the issue is getting past tautology and giving some substa...
September 20, 2017 at 16:58
Sorry, I mean I don't understand what this says:
September 20, 2017 at 02:02
What?
September 20, 2017 at 01:53
Why is that what he has to show?
September 20, 2017 at 01:12
There's coffee. There had been, a long time ago, a study linking coffee consumption to increased risk of cancer. But coffee drinkers are more likely t...
September 20, 2017 at 00:41
That misses the point. Gettier just constructs an artificial example to show how this works. It happens when you think you're testing p but you're act...
September 19, 2017 at 20:19
My version of the story goes like this: Smith puts the odds of Jones owning a Ford at 9-1, and the odds of Brown being in Barcelona at 1-99, so the od...
September 19, 2017 at 16:50
In my last response, I ignored -- God knows why -- that in my model, we've got a probability for q, so some of that was crosstalk. I am actually inter...
September 19, 2017 at 08:22
This is worth quoting again. If someone tells Smith that as a matter of fact Jones does not own a Ford, what happens to my jars? We dump all the reds ...
September 19, 2017 at 02:50
I think I take the ground being wet as evidence that it rained recently because rain makes the ground wet. How do you describe this scenario?
September 19, 2017 at 02:25
Right, I mean exactly that: if you believe that p, there's nothing contradictory about believing that ¬p?q and believing ¬p?¬q. It just means you get ...
September 18, 2017 at 22:25
We can leave out my habitual translation: 9. (¬p?¬q) & (¬p?q) 10. (F?T) & (F?F) 11. T As I said, it's all of those false premises in 10 that are annoy...
September 18, 2017 at 22:19
3. p v ¬q 8. p v q 9. (p v ¬q) & (p v q) 10. (T v T) & (T v F) 11. T 3 and 8 are not contradictory. You have p as a premise, so you can get anything y...
September 18, 2017 at 22:06
Okay. I'll look again, but doesn't that mean your premises must have been inconsistent?
September 18, 2017 at 21:19
Where does 1 come from? Smith does not believe Brown is in Barcelona, but he doesn't believe Brown is not in Barcelona. If he did, the whole exercise ...
September 18, 2017 at 20:40
I think if you believe probably A, then you (should) believe probably what's entailed by A, and that's how Gettier treats justification. Look at the j...
September 18, 2017 at 20:38
And I still find this peculiar. Gettier tells us in so many words that he accepts (g), (h), and (i). The argument has to be that he shouldn't or could...
September 18, 2017 at 19:17
But it gets you "probably p v q" doesn't it? That's all Gettier needs p for.
September 18, 2017 at 18:58
I'd still say this is unclear in Gettier's text, and what's more it's an interesting case, because we often do want to reason from premises we only ho...
September 18, 2017 at 18:57
And I'm not willing yet either to give up using or forbid others from using standard rules of inference. We don't like the result, agreed. So we need ...
September 18, 2017 at 18:44
Don't know anything about relevance logic, but my intuition throughout has been that the justification for believing p turns out to be irrelevant to t...
September 18, 2017 at 18:39
Hmm. Not right. We do want the other principle at work to relate directly to our standards of rationality.
September 18, 2017 at 18:36
But that's just the usual issue with material implication.
September 18, 2017 at 18:34
If you have "probably", you don't need "possibly" to stand in for "improbably": "probably" already covers both. "Possibly" is already in the backgroun...
September 18, 2017 at 18:31
Now this I agree with completely! But this is not an issue with logic per see, but something else. That something else could be Grice's maxims, for in...
September 18, 2017 at 18:21
The whole point of Gettier's Case II is that it's a bizarre coincidence that Smith's belief is true, and true for reasons that have nothing to do with...
September 18, 2017 at 17:33
Isn't this what "probably p" already says? Why do this superposition analysis at all? Do belief and conception vary freely, or is there some relation ...
September 18, 2017 at 17:12
? Are you using "entail" in some special sense?
September 18, 2017 at 16:45
Dang. I knew it was a mistake to speak for someone else.
September 17, 2017 at 22:21
I (and I think @"T Clark") don't see how you and Rich can believe in a life force, and y'all don't see how we can't. If there's some common ground, th...
September 17, 2017 at 21:59
Agreed. People find material implication and inclusive disjunction counterintuitive, and then mistake their objections to them for objections to argum...
September 17, 2017 at 21:54
Because A ? B ?(¬A?B), I guess. That means ?-introduction comes to P?(¬P?Q) for any Q, which, duh.
September 17, 2017 at 21:30
That puts the probability of A ? B at 1. I put it at 0.901. Why would you put it at 1? Suppose you're also pretty confident that Brown is in Barcelona...
September 17, 2017 at 21:21
Gettier nowhere says that Smith believes Jones owns a Ford, only that he has good evidence for this belief. Let's say he thinks it highly probable. We...
September 17, 2017 at 19:26
Well what we'd look for if we did want to head down this road is behavior. For example, there's Ramsey's famous suggestion about how to measure degree...
