Johann Georg von Zimmermann

Never lose sight of this important truth, that no one can be truly great until he has gained a knowledge of himself, a knowledge which can only be acquired by occasional retirement.

—Johann Georg von Zimmermann

Open your mouth and purse cautiously, and your stock of wealth and reputation shall, at least in repute, be great.

—Johann Georg von Zimmermann

Be not so bigoted to any custom as to worship it at the expense of truth.
