Just to note, by the way, that this whole thing started because I had said, "That something is non-identical through time doesn't imply that there's no connection through time," and then you asked me to elaborate that, so I did.
Fair enough. One might think that 'personal identity' is a subclass of the much broader class of 'identity' but if there is no identity over time, then personal identity is just a way of talking. The 'identity' part of 'personal identity' is far too loose. Yes? Personal identity literally can have nothing to do with identity if identity doesn't persist across time. Do you agree?
Let's look at each of your connections with reference to this central question: Why should nervous Alex (Alex1) be nervous about becoming tortured Alex (Alex2)?
1. Causal connection. The executioner's feeling of duty is causally connected to Alex's anguish. [in other words the executioner has a 'brain state' that is causally connected to Alex's anguished 'brain state'] Does that mean that the executioner should be nervous about the torture he himself is to soon feel, being causally connected to it? Clearly not. So causal connection does not get at the matter.
2.Contiguity. The executioner's blade is contiguous with alex's flesh, both in space and in time. Does that mean the blade should be nervous about the torture it is to soon feel? Clearly not. So contiguity does not get at the matter.
3. Memory. If nervous Alex is aware he'll be knocked unconscious prior to execution and given a drug that'll prevent recollection, would he be right not to be nervous about the impending torture (since, at that time, he won't remember earlier states?) Clearly not. So memory does not get at the matter.
4. Sense of self. Well what is this? Is the sense of self a physical thing? Is it a brain state? But if it's a brain state the only way it can extend across multiple brain states is to be connected. Through what? Through a sense of self! But what is a sense of self. Is it a brain state? But if it's a brain state...
Ok, let's do a recap and recall how we got here.And what did my comments have to do with supporting whether someone has a "good reason" for feeling some way?
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?
That something is non-identical through time doesn't imply that there's no connection through time.
"[For T1 Alex looking ahead to the torture of T2 alex] There's nothing to worry about. Is this fair? If not, why not?"
You ask me to explain the causal connection of the torturer to the victim. I do. — csalisbury
Terrapin cited causality as one explanatory factor. This is what I was responding to - in terms of the argument, I'm making no commitment to any theory of causality - I'm trying to demonstrate that if one appeals to causality here, it fails on its own terms. — csalisbury
The world of philosophy is huge! But an argument cannot progress if we spend it hunting influences, seeking proper names. If we do this, we become more like birdwatchers than philosophers, seeking examples in the wild by their distinguishing marks. It is far more fruitful to follow the argument itself, and where it leads. — csalisbury
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. — csalisbury
I explained this already. First, I'm talking about identity in the sense of logical identity, not personal identity. Again, these refer to two quite different ideas conventionally. — Terrapin Station
Do you say consciousness reduces to physical stuff or are you eliminative? — Mongrel
I'm not at all an eliminative materialist. I say that consciousness is identical to physical stuff--namely, to particular brain states. If you want to say "reduces to" that's okay, although reductionism is often characterized in a way that I don't agree with, but arguably it's a straw man characterization.
I'm not using logical identity in any sort of novel manner. Just plain old morning star=evening star identity. — Terrapin Station
'I say that consciousness is identical to physical stuff'
But you also say:
' I'm talking about identity in the sense of logical identity, not personal identity. Again, these refer to two quite different ideas conventionally.'
Is what you call 'personal' identity identical to physical stuff? Is 'oneself' wholly and solely physical? If it is, then how is there a difference between 'conventional' and 'personal' identity? If it isn't, what's the difference? — Wayfarer
Personal identity is the concept you develop about yourself that evolves over the course of your life. This may include aspects of your life that you have no control over, such as where you grew up or the color of your skin, as well as choices you make in life, such as how you spend your time and what you believe. You demonstrate portions of your personal identity outwardly through what you wear and how you interact with other people. You may also keep some elements your of personal identity to yourself, even when these parts of yourself are very important.
Personal identity: What is it that makes a person the very person that she is, herself alone and not another, an integrity of identity that persists over time, undergoing changes and yet still continuing to be — until she does not continue any longer, at least not unproblematically?
The problems of personal identity:
* Who am I? (in the above sense)
* Personhood--what is it to be a person?
* Persistence--what does it take for a person to persist from one time to another
* Evidence--how do we find out who is who?
* Population--If the persistence question asks which of the characters introduced at the beginning of a story have survived to become those at the end of it, we may also ask how many are on the stage at any one time.
* What am I? What sort of things, metaphysically speaking, are you and I and other human people?
So, if you don't agree that meaning can be expressed consistently between different people, and that different people all mean different things by words, how is debate possible? — Wayfarer
So you're a physicalist who's maybe a little foggy on how to characterize consciousness. — Mongrel
I think I could point out some ways it looks like you're walking around a philosophical minefield. — Mongrel
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
