Love can do much, but duty more. - Johann Wolfgang von Goethe

"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."

"Knowing is not enough; we must apply. Willing is not enough; we must do."

"Let mental culture go on advancing, let the natural sciences progress in even greater extent and depth, and the human mind widen itself as much as it desires: beyond the elevation and moral culture of Christianity, as it shines forth in the Gospels, it will not go."

"If you treat an individual as he is, he will remain how he is. But if you treat him as if he were what he ought to be and could be, he will become what he ought to be and could be."

"Let mental culture go on advancing, let the natural sciences progress in even greater extent and depth, and the human mind widen itself as much as it desires: beyond the elevation and moral culture of Christianity, as it shines forth in the Gospels, it will not go."
