They don’t need to. Your questions make no sense. It’s the brick hitting the window that breaks the window, not the argument “if the brick hit the win...
Verificationists, as I said. Nothing unknown is true, because to be true is to be verified, but not all propositions have been verified, and so they d...
In the type of arguments we deal with, an argument is valid if the truth of the premises entails the truth of the conclusion, and an argument is sound...
The difference is that normally we use the material implication as an actual implication, as in the truth of the antecedent implies the consequent. Be...
I've said; the premises being true are what make it sound. Nothing. Your argument has no practical use. I have to evaluate the truth of your conclusio...
By proving that the conclusion follows from the premises and that the premises are true. In your case to prove the second premise I must confirm that ...
It's not enough to present a valid argument. You have to show that the argument is sound, i.e. that its premises are also true. My name is Michael If ...
There is no problem of omniscience. Using verificationism as an example, if one is omniscient then for every meaningful proposition p either p or ¬p h...
It isn't. The argument is only a proof if you can prove 1 and 2 to be true. A deductive argument can have false premises after all. How do you prove 2...
I'm not sure there's really a problem then. If premise 1 is true then premise 2 is true only if the cat is on the mat. So the realist can say that the...
You're forced by necessity to work, not by other people. Other people simply give you more opportunities to work. You need food to live, and so some w...
You're equivocating. To say that C is black and circular is to say that C has the colour-property black and the shape-property circle. Colour properti...
And that's precisely why I believe that realism cannot account for token identity in cases like this. Token identity cannot be reduced to the mind-ind...
Everyone who considers the ship of Theseus or grandfather's axe and others like it. It has a long tradition in philosophy, going back to Heraclitus an...
Of course they do. If you and I are at the pub each drinking a pint of beer it matters if I'm drinking from your glass or mine. Whether or not he retu...
The same type, but different tokens. When you and I each drink a glass of water we're not drinking from the same glass of water. Even if the two glass...
You're addressing the discrepancy with natural language? Ordinarily we understand "If X then Y" as asserting that if X is true then Y is true because ...
There is more than one hydrogen atom in the universe. The existence of water depends on it. It's two hydrogen atoms and one oxygen atom. It might not....
Two ships can have the same structure and function, yet they're two ships, not one ship. Again, you're conflating the type-token distinction. The ship...
We can say it's the same ship if we like. If I smash a mirror then the broken pieces are the mirror that I used to use to look at myself. If I smash a...
In the example of them using the replaced pieces to build a second ship there are two ships with a similar structure to the original. Are they both th...
That still doesn't address the question though. Imagine instead of discarding the replaced pieces they are used to build a second, identical ship. Whi...
Philosophers discussing the metaphysics of identity, and whether or not "it's the same ship" is true and if so whether its truth should be understood ...
Of course it matters. Imagine instead of discarding the replaced pieces they are used to build a second, identical boat. Which of the two boats is the...
As I've repeatedly said, two different ships can have the same structure. Why is the ship that returns the same ship and not a copy with the same stru...
Then look to what you first said in this topic: And what you said later: You accept that whether or not there are two ships or is one ship is an issue...
And again I’m not just saying that we use the same name for the ship. In fact we might even use a different name, as a rechristening during the journe...
Which makes the truth a matter of convention, or even personal opinion (as I don’t need other people to agree with me; I can decide for myself whether...
We all agree that the material has changed but the function remains. The disagreement is over whether it's the material or the function or the sense o...
We don't start by defining "ship" according to some strict criteria and then use it in conversation. Rather we talk about a ship leaving, a ship retur...
It's both. Vague propositions often don't have a single truth value, precisely because they're vague. I'm not saying that it can't be determined. I'm ...
It's the difference between there being two ships with the same name and there being one ship (which maintains its name). There are other people named...
It doesn't require a narrative description, but your example of a person being both young and old is a good example. "Young" and "old" don't have a cl...
I think you have a very strange understanding of language if you think that when I say that the ship that returns is the ship that left that I'm not a...
Other possible examples are statements about the future (especially if there is free will or some things are actually random) and counterfactuals, alt...
The ship that leaves is the ship that returns. Although my main support of anti-realism is in the rejection of recognition-transcendent truth conditio...
Anti-realism isn't unrealism. Anti-realism doesn't argue that people aren't real. Anti-realism argues that truth isn't recognition-transcendent and/or...
Two different ships can have the same model, have material bound the same way, function the same way, and yet they are two different ships, not the sa...
