Talk often, but never long: in that case, if you do not please, at least you are sure not to tire your hearers.

When we are in the company of sensible men, we ought to be doubly cautious of talking too much, lest we lose two good things, their good opinion and our own improvement; for what we have to say we know, but what they have to say we know not.

When you have nothing to say, say nothing.

We have two ears and one tongue in order that we may hear more and speak less.

... you simply can't imagine what men will say!

Conversation is the laboratory and workshop of the student.

How can I tell what I think till I see what I say?

Education begins a gentleman; conversation completes him.

It is by speech that many of our best gains are made. A large part of the good we receive comes to us in conversation.

The older I grow, the more I listen to people who don't say much.
