NS,
It's not false because I'm not using it to imply that what Alan states he can do, can be done which is the stretch you've put on it. That's why I added the note.
It’s false because analogies require different objects with the same or sufficiently similar properties such that inferences can reasonably be drawn. AB’s “I can consciously control my thoughts” isn’t the same or sufficiently similar to “I can swim” for obvious reasons, whereas “I can fly unaided” would be.
Here’s Wiki making the same point:
“T
he process of analogical inference involves noting the shared properties of two or more things, and from this basis inferring that they also share some further property.[1][2][3] The structure or form may be generalized like so:[1][2][3]
P and Q are similar in respect to properties a, b, and c.
P has been observed to have further property x.
Therefore, Q probably has property x also.
The argument does not assert that the two things are identical, only that they are similar. The argument may provide us with good evidence for the conclusion, but the conclusion does not follow as a matter of logical necessity.[1][2][3] Determining the strength of the argument requires that we take into consideration more than just the form: the content must also come under scrutiny.”
https://en.wikipedia.org/wiki/AnalogyIf you want to change it to flying, I don't mind but at the same to make sense, then you are going to have to attach a ton weight to him, and it will prove nothing.
No I’m not. Just flying unaided is sufficient for the analogy to work (ie two different claims with the same or sufficiently similar properties of collapsing under rational scrutiny and having no evidence to support them). Adding the ton weight breaks the analogy though because it would create two dissimilar claims for reasonable inference purposes.
The point is that asking someone to do not think of something to show that they can control their thoughts is like attaching the ton weight in either flying or swimming.
No it isn’t – see above. If AB wants to claim to be able to “consciously control” his thoughts, then it should be a cinch for him to consciously control his thoughts such that he chooses not to picture in his mind’s eye the next object that’s written on the screen in front of him. He can’t do that though – hence we have an example of AB not being able to consciously control his thoughts at all.
This should give him pause, even though (predictably) it doesn’t..
Alan's claims fall not becausecof physical impractibility but because of logical incoherence.
Yes, AB’s claims are incoherent. Even if we infer what he’s trying to say though, they also fails because he cannot do the things he think he can do (however incoherently expressed).
Say in an extension of your approach, Alan goes out and turns his head left, and sees a bus careening towards him. He's not able not to think 'bus!!!!!' but he would say he is able to decide to get put the way and in what way. So the specific inability to choose is not indicative of a general ability.
And similarly if he claimed to be able to fly unaided, jumped out of a window and wound up in hospital that wouldn’t necessarily mean that he wouldn’t flutter gracefully to the ground the next time he tried it. Your critique here is a straw man though – inviting him to “consciously control” his thoughts such that he didn’t picture an elephant and a banana wasn’t intended to disprove his general claim of conscious control (other reasoning that he just ignores does that) – rather it was just intended to demonstrate to him that he can’t do the thing he claims to be able to do.
Setting up tests for logically incoherent claims is logically incoherent.
No it isn’t – that’s often how thought experiments work: “Your claim is incoherent. Nonetheless, if we extract from it your general thesis we can still falsify what it would imply if it was coherently expressed”. If you subject “I can control my thoughts” to rational analysis it’s incoherent. It’s also though a sentence that scans as well as “I can fly unaided” scans, so can be tested at that level too.
The claim "god" for example is equally incoherent, but atheists here readily discuss the implications of "god" existing rather than just slam the door on theists with "but that's incoherent so there's nothing to talk about". It's a sort of convenient fiction - "let's both pretend that your claim about that isn't incoherent so we have something to discuss".
