Sign Languages are not just Languages, they are LANGUAGES

The title of this blog is the answer to a question. What is that question? I'm giving a clue only this time, but I'll return to this thought when I get two minutes to spare.

The clue: The following was the question asked, decades before, in the end-semester exam of a reputed philosophy Course. It goes without saying that the student became a well-known philosopher though he got FR grade only, in the test.

Q: Is this a question?
A: If this is an answer!

[Meanwhile, my dear reader, why don't you post something about sign languages in the comments section? I can put it in the main page. thanx.]
