Marie von Ebner-Eschenbach

Imaginary evils are incurable.

Nobody knows enough, but many know too much.

Exceptions are not always the proof of the old rule; they can also be the harbinger of a new one.

So soon as a fashion is universal, it is out of date.

Those who understand only what can be explained understand very little.

We are so vain that we even care for the opinion of those we don't care for.
