Talents are nurtured best in solitude, But character on life's tempestuous seas!

Our foibles are really what make us lovable.

Do thine own task, and be therewith content.

Nature knows no pause in progress and development, and attaches her curse on all inaction.

We know accurately only when we know little, with knowledge doubt increases.

No one can take from us the joy of the first becoming aware of something, the so-called discovery. But if we also demand the honor, it can be utterly spoiled for us, for we are usually not the first. What does discovery mean, and who can say that he has discovered this or that? After all it's pure idiocy to brag about priority; for it's simply unconscious conceit, not to admit frankly that one is a plagiarist.

He is a man whom it is impossible to please, because he is never pleased with himself.
