I have always paid attention to the merits of my enemies, and found it an advantage.
Johann Wolfgang von GoetheDon't give us your doubts, gives us your certainties, for we have doubts enough of our own.
Johann Wolfgang von GoetheNo 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.
Johann Wolfgang von GoetheThe affairs of the world are no more than so much trickery, and a man who toils for money or honour or whatever else in deference to the wishes of others, rather than because his own desire or needs lead him to do so, will always be a fool.
