I understood every word which had up to then been spoken at the meeting, and when I spoke myself I felt that they understood.

That is an experience which every speaker has in a certain way and up to a certain point.

He knows by some kind of instinct if his hearers are with him; if they respond, they must certainly have understood.

Last night this was marked.

I felt it every instant I was talking and when I came to realize that the men were in strict accord with my general views, I took them into confidence with regard to my own personal purpose.
