He was screaming in agony, and there was nothing we could do.

Listen, someone's screaming in agony - fortunately I speak it fluently

I should say that nothing we do can be an adequate response to the agony we've seen, ... I am grateful to all the folks who have given.

A screaming comes across the sky. It has happened before, but there is nothing to compare it to now.

I used to believe that anything was better than nothing. Now I know that sometimes nothing is better.

The utmost extent of man's knowledge, is to know that he knows nothing.
