Those who know nothing of foreign languages know nothing of their own.

Wir sind gewohnt, daß die Menschen verhöhnen,Was sie nicht verstehn.

No one has ever properly understood me, I have never fully understood anyone; and no one understands anyone else

It is not easy in this world for one person to understand the next one.

So long as you live and work, you will be misunderstood; to that you must resign yourself once and for all. Be silent!

And we went our separate ways without having understood each other. As in this world nobody understands the other easily.

All understanding begins in wonder!

Whatever you cannot understand, you cannot possess.

What one doesn't understand one doesn't possess.
