Nothing is worth more than this day. - Johann Wolfgang von Goethe

"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."

"Character develops itself in the stream of life."

"Life belongs to the living, and he who lives must be prepared for changes."

"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."

"All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, until they take root in our personal experience."
