"You now are distinct from the Dave Pizer who existed yesterday. The

for each day/hour/minute/second of your life? In what way does
your brain continue the same?"


Let me repeat my argument.

X is really distinct from Y if and only if X can exist without Y and Y can 
exist without X. 

If you are a continuation and lets call that X, and Y of yesterday WAS you 
then, but it was not distinct  then.  So it was not distinct then.  It was 
not a duplicate then.
And Y does not exist now, so there never is/was a time in your example, that 
I can see, where a self and a duplicate exist at the same time.  So it is not 
a counter-example to my principle, at least not that I can see.


This may have implications to show that either what some people call a 
duplicate is not really a duplicate  - its the same thing at the same time 
and at a different time one of the entities cannot exist so the type of thing 
that you are describing does not meet the definition of  being distinct and 
so that is not an example of a duplicate.    

We need to look for a duplicate that is the same thing at the same time.  
What you were yesterday was what you were yesterday, it IS different from you 
of today, or tomorrow, but at that time one of the entities does not exist so 
there never is a time when a duplicate of you existed under this thought.???

Huh?
