Are we what we do?
 

If we are what we do, but we stop doing it, what becomes of us?

How could you possibly stop doing what you do? What you do is defined by what you do (duh!), and hence the only way to stop doing it, is to drop dead.
As a result, what becomes of us, is that we die.

What was your point? Can you convince me that your question wasn't entirely devoid of meaning?

We are not what we do. We are what we are.
If we are what we do and we don't- we aren't?

My objection still stands.

A question such as this would be more at home in Tilted Nonsense, than Philosophy.

There is nothing profound about being meaningless.

If this sentance was a piece of toast, how would you fly to Japan in it?
