"It is a very hard and troublesome..." - Quote by Johann Wolfgang Von Goethe

“Perfection is the measure of heaven, and the wish to be perfect the measure of man.”

“I wish the stage were as narrow as the wire of a tighrope dancer so that no incompetent would dare step upon it.”

“Properly speaking, we learn from those books only that we cannot judge. The author of a book that I am competent to criticise would have to learn from me.”

“It is art, and art only, that reveals us to ourselves.”

“To know that one knows what one knows, and to know that one doesn't know what one doesn't know, there lies true wisdom.”

“Every truth has four corners: as a teacher I give you one corner, and it is for you to find the other three.”

“Men are more apt to be mistaken in their generalizations than in their particular observations.”

“Habit is the nursery of errors.”

“A long habit of not thinking a thing wrong gives it a superficial appearance of being right.”
