标题Re: [讨论] 关於因果链....

Sorry, my laptop crashed. can't type in chinese at the moment. so please bear
with me.
Seems to me that IsaacStein has made it clear that for Kripke, Aristotle (
the person) could have been given any other name (such as Adam, if you will)
It might righly be wondered that if that's the case, why the name "Aristotle"
refers to Aristotle the person in all possible worlds? Why doesn't it fail to
refer in a world where Aristotle the person is named "Adam"?
Think about the following statement
"Aristotle could have been named Adam".
or "It could have been the case that Aristotle was named Adam"
Kripke's point, I take it, is that in all the counterfactual worlds,
Aristotle must refer rigidly to Aristotle the person. Otherwise, the
counterfactual statement is not really about Aristotle but rather about
someone else. But remember, what we are talking about here in the
counterfactual statement
is that "Aristotle" could have been named Adam. Not anyone else.
So "Aristotle" must refere to Aristotle the person in all counterfactual
worlds (or situations).
So even in a counterfactual world where Aristotle is named Adam, the proper
name "Aristotle" still refers rigidly to Aristotle the person whose name
is Adam in that world.
anyway..just my two cents..

: 我们可以设想这样的状况是可能的:
: 可能,在某命名仪式中,亚理司多德并不被命名叫做「亚理司多德」。

: 当我们在进行双重可能性设想时(即在可能世界里进行可能性设想),
