And what did my comments have to do with supporting whether someone has a "good reason" for feeling some way?
Ok, let's do a recap and recall how we got here.
The first line of questioning established that you hold two important beliefs: A person has many many many brain states throughout their life and identity does not persist through time.
This raises an obvious question:
If, as you say, "Your consciousness, your sense of self, etc. are simply brain states re your particular brain" and if identity does not persist over time, then how is it that we talk of the the same person having multiple brain states throughout their life, rather than a myriad of people, one for each brain state?
Either we need a more robust theory of identity, or we need a robust conception of some other type of continuity.
It is useful to examine a problem as abstract as this by focusing on a concrete and visceral example: Alex is worried about his future torture because he believes that he (not someone else) will experience that torture.
Here is what I said:
Thus if nervous Alex (brain state 1) is nervous because he is about to be tortured (this will be agonizing brain state 2) (I'm abstracting here! of course there are multiple brain states throughout!) then he is confused. He won't be the one being tortured. There's nothing to worry about.
Is this fair? If not, why not?
Let me break this down. I'm offering a hypothetical example of a man awaiting torture according to the viewpoint of someone who neither believes in the persistence of identity over time nor has supplied an alternative, robust explanation of continuity. I am not insinuating that, based on your own beliefs, you ought to agree with the scenario as I've presented it. I'm offering up something absurd as a foil that will allow you to articulate your own position.
Importantly, this is where the 'good reason' comes into play. "There's nothing to worry about. Is this fair? If not, why not?" is synonymous with 'does he have a good reason to worry [that he, not some different future alex, will suffer?]" It's possible that you may not be familiar with this usage of 'good reason.' It's very common among the english speakers I know, but perhaps it's a regional thing. If so, I apologize for the confusion.
As I'd hoped, you did not simply agree with my scenario (implicitly agreeing that yes, there is something Alex has to worry about) but began tentatively to articulate a corrective:
That something is non-identical through time doesn't imply that there's no connection through time.
Now we're getting somewhere. We seem to both agree that we'd be worried if we were soon to be tortured (while we may not agree about whether we can worry about existing again after death, we understand worrying about things that will happen to us within our own lifetime.) To understand this, we ought look not to identity, but to
connection.
I then asked you to explain what you meant by connection here, since it's doing a lot of work! You gave some reasons and I explained why those reasons, while fine, are not enough to explain why one would be worried about one's future torture.
Note where we are in terms of the argument: We are still trying to understand why the fear of impending torture is different than the fear of existing again after death. This significance of this question is that identity and brain-states alone don't explain why you, I, anyone would worry about our future torture. You have recognized this and offered the additional idea of 'connection'
So you offer a quick sketch of what you mean by connection, I explain why it seems insufficient to address the question at hand.
And that's where everything goes haywire.
You ask me to explain the causual connection of the torturer to the victim. I do. You ask what my point is. I say my point is that causal connection cannot explain why T1 Alex has a good reason to worry about T2 Alex's suffering, as you had implied. Instead of responding to the argument, you say that you never said anything about 'good reasons' (though it's perfectly clear what 'good reason' means in this context) and then to talk about the nature of justification and fact.
What I want to do is to take up where we left off. If there's something particularly irksome about the term 'good reason' to you, I am all too happy to jettison it, because I'm interested in the argument itself.
So to return once more to where this all came from
"[For T1 Alex looking ahead to the torture of T2 alex] There's nothing to worry about. Is this fair? If not, why not?"
Again, I would love nothing more than to continue this conversation in good faith.
So here is where we are: You laid out what you meant by 'connection.' I responded with my doubts. Can you respond to that? You still have not.
