He who knows no foreign languages knows nothing of his own.

The highest cannot be spoken; it can only be acted.

We can redeem anyone who strives unceasingly.

The summit charms us, the steps to it do not; with the heights before our eyes, we like to linger in the plain. It is only a part of art that can be taught; but the artist needs the whole. He who is only half instructed speaks much and is always wrong; who knows it wholly is content with acting and speaks seldom or late.

By seeking and blundering we learn.

I will be lord over myself.

To rule is easy, to govern difficult.
