For those of you familiar with the programming language C, here is 
something I thought of to distinguish intensionality with-an-s from 
intentionality with-a-t. 

Consider the following example using pointers:

int i, j;
int* p1, p2;

i = 2;
j = 2;

p1 = &i; /* &i means the address of i */
p2 = &j; /* &j means the address of j */

So, the evaluation of the statement

p1 == p2

would return false.  For, what is stored in p1 and p2 are the memory 
addresses of i and j.

However, the evaluation of the statement:

*p1 == *p2

would return true since the value pointed to (dereferenced) by p1 and p2 
is the same value.

Thus, p1 and p2 have "something" which are not substitutable for one 
another.  Namely, the memory address assigned to them.  But, by using 
the dereference operator, they refer to the same value.

Thanks Bill.  For more on this topic, take a look at:

"Intensionality vs. Intentionality"
http://www.cse.buffalo.edu/~rapaport/intensional.html

and for a discussion of it in the context of AI and knowledge
representation (including epistemic logic, for those of you who know
what that is):
