"P is a syntactically correct program in some well-defined 
Turing-complete language. Does P stop when it is applied to this 
data X?" is a meaningful and well-formed question. It's not a 
Carrollian question like Olcott's "what time is it, yes or no?" 
It has a sensible answer. Either P stops for X, or it doesn't.

It's a question that can in many (but not all) cases be answered 
quickly and easily enough (and correctly) by humans, often 
requiring no more than a brief glimpse. (I say 'not all' only 
because it is not beyond the wit of mankind to trump up 
extraordinarily complicated and deliberately obfuscated code that 
might easily defeat a programmer's casual glance.)

Some simple examples in K&R C:

main(){}

main(){for(;;);}

main(){puts("Hello");}

#include <stdio.h>
main(){long c=0;int ch; while((ch = getchar()) != 
EOF)++c;printf("%ld\n", c);} /* input: the complete works of 
Shakespeare */

Any competent C programmer can solve these at a glance - Halts, 
Loops, Halts, Halts, in that order - so why shouldn't a 
programmer be able to?

The Halting Problem asks a more complicated question. ``Is it 
possible to write a program that answers the above question for 
arbitrary P and arbitrary X?"

Again, the question is meaningful and well-formed. It's 
syntactically and grammatically adequate, and anyone claiming not 
to know what it means is laying themselves open to a charge of 
disingenuousness. The only difficult part is the answer, but 
there's nothing self-contradictory or self-referential or 
paradoxical about the question.
