To the Editor:

I applaud your article, as it is really important for people to realize that 4,000 is not just a number. Very simply, the best thing that we as a nation can do to honor their memory is to end this war.

To the Editor:

The number 4,000 is no more significant than was No. 1 or 3,999 or any in between. Each one reminds us of our solemn duty to finish what they started, so that their deaths not be in vain.

Note from KBJ: The letter writers appear to be having a disagreement. There are three types of disagreement: factual (about how things are), evaluative (about how things should be), and conceptual (about the nature of a concept). What sort of disagreement are the letter writers having?
