Difficulties increase the nearer we get to the goal. - Johann Wolfgang von Goethe

"There are only two lasting bequests we can hope to give our children. One of these is roots, the other, wings."

"If I love you, what business is it of yours?"

"Es ist nicht genug, zu wissen, man muß auch anwenden; es ist nicht genug, zu wollen, man muß auch tun."

"The mediator of the inexpressible is the work of art."

"Man is not born to solve the problem of the universe, but to find out what he has to do; and to restrain himself within the limits of his comprehension."
